Soil preparation includes deep plowing, deep plowing, extermination of plowing, rotary tilling, plowing, and basal fertilization, and the use of multi-functional joint-operated implements in areas where conditions permit. We should vigorously promote and promote conservation tillage techniques and deep-sown operations.
Former treatment. The northern spring corn is mainly corn borer or soybean, wheat, potato, sugar beet and sunflower. The former residue is removed or shredded and returned to field according to specific conditions. Soybeans are soft pods, which can be used to plant corn on the original ridge after locust removal, or to adopt deep sag, hoeing, and fertilization; wheat sorghum can timely replenish eucalyptus after wheat is harvested, or carry out undulation or stir wheat ridges; Ridge or broken ridge compaction; corn borer is the first use of extermination after the deep plowing or plowing soil preparation and straw on-site crushing covering the field no-tillage sowing and other methods.
When the length of the straw covering the ground is too long, it can be crushed with a straw crusher before sowing.
Tillage technology. The spring corn field should be crushed, extirpated, deep plowed or deep-soiled in time after the harvest. If it is necessary to apply farmland fertilizers, it should be spread evenly before loose tillage, and be turned into soil in combination with loose tillage. The depth of deep plowing should be more than 25 cm, and the depth of deep plowing should be 30-35 cm. After loose plowing, we can reach the leveling of the ground, the soil is finely chopped, and the Panasonic is ready. Deep and deep plowing can accelerate soil maturation and increase effective nutrients; deepen the tillage layer to facilitate the development of the root system; improve the ability to penetrate and retain water, which is conducive to drought resistance; and can also eliminate weeds and reduce pests and diseases. The use of high-powered tractors to haul large-scale hoe cultivators for deep-soiling, hoeing, and smashing of soil is completed at one time, realizing the joint land preparation operation of Songliao. The quality is good and the speed is fast, which is the trend of future development. It should be noted that sandy loam soil should not break the bottom layer of the plough in order to prevent leakage of water and fertilizers; it should be prevented from falling over in order to prevent damage to the soil structure.
Mechanized deep loose technology. Refers to the use of mechanical loosening of the soil, breaking the bottom of the plough, and deepening the tillage layer. Deep soiling does not tip the soil, and in the case of maintaining the original soil layer, improve soil permeability, improve soil water storage capacity, and ripen deep soil, which will facilitate the deep rooting of crop roots and increase crop yield.
Fill the bottom with water. In areas with dry soils and heavy sandstorms in spring, wherever there are water conservancy conditions, the bottom of the river should be filled with water to ensure timely sowing of spring corn, seedlings and seedlings. It is best to combine deep plowing before wintering. In winter, when the temperature is low, the soil moisture evaporates slowly. After winter irrigation, as long as the soil is preserved in early spring and early spring, the soil can retain large amounts of water. Winter irrigation can prevent spring irrigation from lowering the ground temperature and affect timely planting. It can also avoid the phenomenon of various species of water scrambling in spring, and it can help reduce pests.
Apply base fertilizer (basic fertilizer). Deep application of base fertilizer has two methods: first spreading fertilizer, ploughing, and ploughing and fertilizing. After the first application of the manure, the requirements for ploughing are: the amount of acre applied is consistent with the agronomic requirements, uniform spreading, minimizing the time for the chemical fertilizer to be exposed on the surface, burying it in time, burying it deeper than 6 cm, and having no visible particles on the surface. Plowing and fertilizing, usually the fertilizer box is fixed on the plough frame, the row of fertilizer pipes is installed behind the ploughshare, and the fertilizer is applied to the furrow along with the plough turning and the mulching is covered. The width of the fertilizer belt is 3-5 cm. Uniform continuous, broken rate
Single Packed Mottled Waxy Corn
Waxy corn comes in a variety of colours. Some people wonder if waxy corn is a genetically modified product. In fact, it is not. Waxy corn originated in China. It is caused by a genetic mutation. Artificial selection gradually led to the emergence of a type of tannin.
Waxy corn, also known as waxy corn, is sticky corn. The grain has coarse, waxy endosperm, similar to shiny, glassy (clear) grains such as hard and dented corn. Its chemical and physical characteristics are controlled by a recessive gene (wx), which is located on chromosome 9. 100% of the starch in the endosperm is straight-chain starch.
Coloured glutinous corn is generally white, yellow, red, purple and black, with white, yellow and purple corn being the basic colours. Purple and white hybrids naturally become purple if the purple gene "beats" the white gene and vice versa, so if the two tie we see white and purple corn. Purple can turn into red and black corn, or as we often say, "red is purple and black is purple". Of these colourful corn, the most common yellow waxy corn is the most nutritious as it is rich in carotenoids...
Currently, the only genetically modified foods sold on the Chinese market are soybean oil and papaya. Waxy maize is a hybrid variety and is not associated with genetic modification. Therefore, it can be concluded that glutinous maize is a hybrid variety and has nothing to do with genetic modification.
Genetic modification is a type of "genetic engineering" in modern science and technology, which makes use of modern molecular biology techniques. Hybridisation is the mating of individuals of different genotypes to produce offspring that are different from the original "pure" breed. In a sense, it belongs to the natural exchange of genes that can occur in nature.
