Agrochemical 10 1 High-yield Seed Cultivation Techniques
1 soil preparation
It is required to turn the soil in autumn, and the turning depth should be more than * * * meters. At the same time, combine the deep application of base fertilizer, rake the land accurately, and do not leak tillage, stand, waste or ditch.
2 wide ridge
Make a wide ridge with a width of about 90 cm at the bottom and 65 cm at the top, and merge the original three 60 cm small ridges into two wide ridges. It is beneficial to soil and water conservation to suppress them in time after ridging.
3 fertilization
Apply 2,000-3,000 kg of high-quality agricultural fertilizer per mu as base fertilizer, 20-25 kg of compound fertilizer, 0/~/0.5 kg of zinc fertilizer, 25-30 kg of topdressing urea per mu in late June, or about 50 kg of special corn fertilizer before sowing.
4 Selection of improved varieties
The germination rate of the selected seeds should be kept above 94%, the purity and purity should be above * * *, and the water content should not exceed * * *.
5 seed coating
Select 35% Duokefu suspension seed coating agent and 20% Foucault suspension seed coating agent, and mix them evenly according to the drug-seed ratio of 1: 50, and dry the coated corn seeds in the shade before sowing. Before coating, germination and sowing should be carried out, and the dosage of coating agent should be strictly controlled to prevent phytotoxicity. Corn growers can directly select materials at the planting site, and according to the number of corn seeds to be planted, the corn seeds can be coated by the currently recognized simple method of "plastic bag roll". In the specific operation, it is necessary to mix corn seeds reasonably according to the corresponding proportion, pour the mixed corn seeds into plastic bags and sprinkle the seed coating agent at the same time. The next step needs two people to complete. Tie the mouth of the bag tightly with a rope or rubber band. Everyone grabs one end of the plastic bag and jumps up and down just a few times. The coated seeds after shaking should be stored in nylon textile bags and placed in the shade for sowing.
6 matters needing attention in sowing period
When the soil depth is 5 ~ 10 cm and the temperature is 8℃ ~ 10℃, the sowing date can be selected from the end of April to the beginning of May. In the way of sowing, mechanical equipment such as seeder should be used to assist sowing. It should be noted that plots with poor soil moisture can not be directly sown, and corn seeds need to be covered with soil for about 4 cm and suppressed to ensure soil moisture.
7 planting density
The high-yield cultivation of maize needs to be established in a ventilated and light-transmitting environment, which is determined by the high photosynthetic efficiency of maize. Light intensity not only affects the photosynthetic intensity of maize, but also affects the transportation of photosynthetic products. Because of the large row spacing of corn in planting area and the small paddling resistance of farmland, air plays an invisible role in regulating the climate of corn field during the flow. In this planting environment, the temperature difference between day and night in corn field increases, and the respiration of plants is effectively reduced, which makes the organic matter accumulate in the field and promotes the growth of corn.
Double row planting in maize planting can effectively protect the field ecology, which is one of the widely used technologies at present. Its principle of action is to synthesize two ridges of fields in traditional planting together, and then plant two rows of corn on this basis. Pay attention to the adjustment of row spacing when planting, which can be kept at about 0.4 meters and the ridge spacing is about 0.9 meters. This double-ridge planting technology can make corn grow reasonably, and the fertilizer in the field is not easy to lose. Under this planting mode, the number of corn plants can be increased on the original basis to achieve the goal of high yield.
During the spring ploughing period, relevant technicians need to strengthen the guidance of planting techniques for corn growers, including ridging strategy in the field, fertilization concentration and time of corn seeds, coating method of corn seeds, matters needing attention during sowing and daily management after sowing. Conduct in-depth and meticulous training and guidance in these aspects to ensure high-yield cultivation of corn.
The above is a detailed introduction to the high-yield cultivation techniques of agrochemical 10 1 corn seeds, hoping to help friends who plant agrochemical10/corn seeds. Agrochemical 10 1 corn seeds participated in the regional test of spring corn varieties in East China and North China in 2008-2009, with an average yield of 775.5 kg per mu in two years. In the production test in 2009, the average yield per mu was 780.6 kg, which was * * * times higher than that of the control Zheng Dan 958. In 2008-2009, he participated in the regional test of summer maize varieties in Huanghuaihai, with an average yield of 652.8 kg per mu in two years, which was * * * higher than that of the control Zheng Dan 958; In the production test in 2009, the average yield per mu was 6 1 1.0 kg, which was * * * percentage points higher than the control Zheng Dan 958. So you can safely plant it.
