In the past, in order to ensure supply, the amount of chemical fertilizer was indeed too much, which not only brought about an increase in costs, but also brought some influence to the ecological environment. The current reduction in fertilizers, including the replacement of chemical fertilizers with organic fertilizers, is not about chemical fertilizers, but rather the need to reduce unreasonable use in the past and reduce the momentum of overuse. It is now necessary to promote green development of agriculture, and the replacement of chemical fertilizer by organic fertilizer is a major measure.
Saving costs and increasing efficiency China is a big country producing fruits, vegetables and tea, but its comprehensive benefits are far lower than those of developed countries in Europe and America. An important reason is that the amount of chemical fertilizer is too high. The average fertilizer consumption of fruit trees is 37.4 kilograms, which is more than twice that of Japan, six times that of the United States, and seven times that of the European Union. The average amount of vegetables per mu is 47.6 kilograms. This amount is 12.8 kilograms higher than Japan and nearly 30 kilograms higher than the United States. It is more than 30 kilograms higher than the EU. Now only the use of organic fertilizer can reduce the amount of fertilizer and the production cost can be reduced.
Quality and efficiency increase Now consumers feel that the taste of fruits and vegetables is not as good as it used to be. This is related to the excessive use of chemical fertilizers. Experiments have shown that the orchard with organic fertilizer has obvious improvement in the appearance and intrinsic quality of the fruit. The taste is good, the value of the commodity is high, and the two indicators that may be of concern to everyone, the anthocyanins of the peel, will increase the content by 20% to 30% as long as the organic fertilizer is applied.
To improve environmental agricultural production, on the one hand, soil acidification and eutrophication of water bodies caused by excessive use of chemical fertilizers, and pollution caused by the inefficient use of livestock and manure accumulation, and the problem is solved by replacing fertilizer with organic fertilizer. By replacing the chemical fertilizer with organic fertilizers, the combination of agriculture and animal husbandry is closer, and the use of livestock and poultry manure is also used, which also improves the quality of agricultural products, which is a good thing in one fell swoop.
Why is it that organic fertilizer replaces fertilizer?
At present, the proportion of chemical fertilizers in horticultural crops such as fruits, vegetables and tea in China has reached 40% of the total dosage. Reducing the amount of fertilizer is the focus of future agricultural development. This year, the Ministry of Agriculture issued the “Action Plan for the Organic Fertilizer Substituting Fertilizer for Fruit and Vegetable Teaâ€, which triggered the vibration of the fertilizer industry. Many experts believe that the organic fertilizer industry will usher in the golden period of development.
Jiang Zhiyang, a researcher at the Institute of Applied Ecology of the Chinese Academy of Sciences, believes that the use of bio-organic and inorganic fertilizers can improve the quality of agricultural products, improve the safety of agricultural products, enhance the resistance of crops, and reduce the use of pesticides. It is an effective way to develop modern ecological agriculture and develop vigorously. Promote and use, can effectively solve the pollution caused by agricultural non-point source pollutants such as straw, livestock and poultry manure. “The use of organic fertilizers can increase the amount of organic matter and humic acid in the soil. Organic fertilizers are the best soil remediation agents.â€
Wu Yuguang, former deputy director of the Institute of Plant Nutrition and Resources, Beijing Academy of Agricultural and Forestry Sciences, said that the traditional composting method is used to accumulate contaminated soil, mix pollutants with organic straw, manure, etc., and rely on the action of microorganisms in the composting process to degrade the soil. Refractory organic pollutants.
In view of the problems of small scale production and unstable production in the organic fertilizer industry, Li Ji, a professor at the College of Resources and Environment of China Agricultural University, said that the current organic fertilizer industry is backward in technology, inferior in product quality, and lack of market demand. It is still in the primary stage of development, but the prospects are Very broad.
Regarding the future prospects of organic fertilizers, Li Ji said: “Whether it is an orchard, tea garden or vegetable greenhouse, the promotion of organic fertilizers instead of chemical fertilizers has commonalities. In particular, vegetable production has greater demand for fertilizers and nutrients because of vegetables. The production frequency is high, and the requirements for nutrient concentration and plant absorption efficiency are higher. The pursuit of high quality and high efficiency, the application of fertilizer is indispensable. Therefore, the mode of organic-inorganic mixed fertilization may be more ideal. Applying water-soluble fertilizer through spray drip irrigation The application of organic fertilizer in ditch and hole can effectively improve soil conditions and improve the comprehensive utilization rate of fertilizer."
In the view of Professor Cai Kunzheng from South China Agricultural University, the implementation of organic fertilizer instead of chemical fertilizer needs to be built through a recycling system, establish a stable source of organic fertilizer, and explore a set of alternative models and technical solutions. The technical key to the program is the balance between supply and demand of nutrients in total and time allocation. He believes that the promotion of fertilizer reduction and organic fertilizer replacement requires a clear reward and punishment system. The key to the promotion of the fruit and vegetable tea ecological recycling system is to establish an easy-to-verify government incentive mechanism to promote differentiated market positioning of products.
How to choose the right organic fertilizer for the efficacy and function of organic fertilizer
In recent years, the amount of organic fertilizer in China has increased with the development of agriculture and animal husbandry. Among the nutrients of various organic fertilizers, livestock and manure account for the largest proportion. According to statistics, at the end of 1995, there were 4.1 billion livestock, such as pigs, cattle, horses and sheep, and their excreta accounted for about 60% of China's total agricultural organic fertilizer. However, the current utilization rate is less than 1/3. These organic fertilizers are important nutrients. Resources, if not used, will not only cause waste of resources, but also bring various pollution to the environment.
Under today's market economy conditions, there are still many confusions about the large-scale rational use of organic fertilizers, such as the comprehensive understanding and evaluation of organic fertilizers, the industrialization of organic fertilizers, the modern production technology of organic fertilizers and supporting application technologies. None of them have been properly resolved. Poor management and disposal of livestock and poultry can become an important source of environmental pollution, but it can be a valuable resource after being harmlessly treated and rationally utilized. The following small series will share with you the advantages and effects of organic fertilizer.
Organic fertilizer advantage
1 Compared with fertilizer:
(1) Bio-organic fertilizers have complete nutrient elements; there are only one or several nutrient elements in fertilizers.
(2) Bio-organic fertilizers can improve soils; frequent use of fertilizers can cause soil compaction.
(3) Bio-organic fertilizer can improve product quality; excessive application of chemical fertilizer leads to poor product quality.
(4) Bio-organic fertilizer can improve the rhizosphere microflora of crops and improve the resistance of plants to pests and diseases; chemical fertilizers are single crop microbial populations, prone to pests and diseases.
(5) Bio-organic fertilizer can promote the utilization of chemical fertilizers and improve the utilization rate of chemical fertilizers; the use of chemical fertilizers alone can easily cause the fixation and loss of nutrients.
2 Compared with refined organic fertilizer:
Refined organic fertilizer is a commercial organic fertilizer that is packaged and sold after drying and smashing livestock manure.
(1) The bio-organic fertilizer is completely decomposed, does not burn roots, and does not rotten seedlings; the refined organic fertilizer is not decomposed, and is directly decomposed in the soil after use, which may cause burning phenomenon.
(2) Bio-organic fertilizer is decomposed by high temperature, killing most pathogens and eggs, reducing the occurrence of pests and diseases; refined organic fertilizer is not decomposed, and will cause underground pests when it is decomposed in the soil.
(3) Beneficial bacteria are added to the bio-organic fertilizer, which reduces the occurrence of diseases due to the occupancy effect of the flora; the refined organic fertilizer kills all the microorganisms inside due to high-temperature drying.
(4) The bio-organic fertilizer has a high nutrient content; the refined organic fertilizer causes nutrient loss due to high temperature treatment.
(5) The bio-organic fertilizer is deodorized, light in smell and almost odorless; the refined organic fertilizer is not deodorized, and the stench is formed when the moisture is returned.
3 Differences from farmyard manure:
(1) The bio-organic fertilizer is completely decomposed, and the mortality rate of the eggs is over 95%; the farmer's fertilizer is simple to pile up, and the mortality rate of the eggs is low.
(2) The bio-organic fertilizer is odorless; the farmer's fertilizer has a foul smell.
(3) The application of bio-organic fertilizer is convenient and uniform; the application of farmyard manure is inconvenient and the application of fertilizer is not uniform.
4 Differences with biological bacterial fertilizer:
(1) The price of bio-organic fertilizer is about 800 yuan per ton; the price of biological bacterial fertilizer is expensive, and it is 10,000 yuan per ton.
(2) Bio-organic fertilizers contain functional bacteria and organic matter, which can improve the soil to promote the release of soil-fixed nutrients; biological bacterial fertilizers only contain functional bacteria, and promote the use of soil-fixed fertilizers through functional bacteria.
(3) The organic matter of bio-organic fertilizer itself is the environment in which the functional bacteria live. It is easy to survive after being applied to the soil; and the functional bacteria of the bio-fertilizer may not be suitable for the soil environment.
Organic fertilizer efficacy
Organic fertilizer, commonly known as farmyard manure, refers to slow-acting fertilizers that contain large amounts of biological materials, animal and plant residues, excreta, and biological waste. Organic fertilizer contains not only a large number of elements and trace elements necessary for plants, but also rich organic nutrients. Organic fertilizer is the most comprehensive fertilizer. The role of organic fertilizers in agricultural production is mainly reflected in the following aspects:
1. Improve soil and fertility. After the organic fertilizer is applied to the soil, the organic matter can effectively improve the physical and chemical properties and biological characteristics of the soil, mature the soil, enhance the fertility and buffer capacity of the soil, and create good soil conditions for the growth of the crop.
2. Increase production and improve quality. Organic fertilizers are rich in organic matter and various nutrients to provide nutrients for crops. After the organic fertilizer is decomposed, it provides energy and nutrients for soil microbial activities, promotes microbial activities, accelerates the decomposition of organic matter, and produces active substances that promote crop growth and improve the quality of agricultural products.
3. Improve the utilization rate of fertilizers. Organic fertilizers contain many nutrients but relatively low levels and slow release. Fertilizers have high nutrient content, low composition and fast release. The two are rationally combined and applied, complement each other, and the organic acid produced by the decomposition of organic matter can also promote the dissolution of mineral nutrients in soil and fertilizer. Organic fertilizer and chemical fertilizer promote each other, which is conducive to crop absorption and improve fertilizer utilization.
