After the on-site activities of science and technology to help the farmers in the countryside, the journalists divided the road into the fields and sent agricultural knowledge and cultural programs to the villagers. Among them, reporters from all the way came to Dongwangzhuang Village, Donggu Town, Guanxian County. .
It is understood that Guan County in Liaocheng City is located in the northwest plain of Lu. The existing arable land area is more than 110 million mu. Guan County is a county of grain and high-quality cotton production bases in the country, and it is also one of the top 100 oil-growing counties. Planting garlic, nectarine and other crops are famous.
First, the reporter and Dr. Tan Deshui of the Institute of Agricultural Resources and Environment of the Shandong Academy of Agricultural Sciences visited the nectarine planter Wang Qingfeng's orchard to explain scientific fertigation management techniques.
What kind of fertilizer is required for nectarine? Tan Deshui introduced that the nutrient of fertilizer has a large number of elements and trace elements. A large number of elements are nitrogen, phosphorus and potassium. What is the nitrogen, phosphorus pentoxide and potassium dioxide in the usual fertilizers? This is the main nitrogen, phosphorus and potassium. Nectarine’s demand for these three elements is the largest. Followed by calcium and magnesium, as well as sulfur in the amount of elements, but also more important.
Dr. Tan further explained the amount of fertilizer applied to nectarines: According to the yield, every 100 kg produced requires 0.3-0.6 kg of nitrogen, 0.1-0.2 kg of phosphorus, and the usual potassium oxide, 0.25-0.4 kg. High-yield nectarine fertilizer, generally 25-40 kg of pure nitrogen per acre, according to the soil fertility, nectarine varieties, phosphorus 5-20 kg, potassium oxide is generally applied 15-40 kg. Since nectarine is a kind of fruit tree that prefers nitrogen and potassium, in the fertilizing process, experts recommend that the amount of phosphate fertilizer applied to nectarine should be less than that of nitrogen fertilizer and potassium fertilizer.
In addition, the experts also gave several suggestions for the period of nectarine fertilization. The three periods are more important: When the leaves fall before the winter, it is an important fertilization period. The main application is base fertilizer. The base fertilizer is mainly dominated by organic fertilizer. The organic fertilizer has a long duration of nutrients. It is the differentiation of flower buds in the following year, and it stores large amounts of nutrients. Inside the tree.
In addition to the application of organic fertilizers, chemical fertilizers such as compound fertilizers, urea, and potassium sulfate should also be used. Among them, the application of nitrogen fertilizer accounts for about 40%, and potassium fertilizer accounts for about 50%. Phosphorus fertilizer is used for one-time application.
The second fertilization period is before the nectarine blossoms. Applying a small amount of nitrogenous fertilizer and potash fertilizer, phosphorus fertilizer as a supplement is beneficial to nectarine fruit setting. In the third period of fruit enlargement, a small amount of nitrogen fertilizer and potassium fertilizer can be applied according to the age of the tree, and it can also be sprayed with 0.5% concentration of foliar spray. Urea solution, potassium dihydrogen phosphate solution or potassium sulfate solution.
According to experts, the main fertilization method is ditching. One is to dig a circular groove around peach trees; the other is to dig trenches on both sides of the tree; this year it will be dug on both sides of the east and west, and the next time fertilization can be changed into north and south; and there is a radioactive solar ditch that needs to be half distance from the trunk. Meter distance.
Organic manure is a process of long-term fertility training. Applying chemical fertilizers may be effective in the year, but organic manure is effective all year round. Soil cultivation is good, and it can sustain tree maintenance.

With the development of the times, the purpose of people's work and life is not only to solve the problem of food and clothing, but also pay more attention to health. So now health care products receive more and more consumers. As health food additives, this kind of products play a role in preventing diseases and delaying aging. These products mainly include: bilberry extract, cranberry extract, black elderberry extract, blueberry extract, purple corn extract, acai berry extract. Etc.
