1. What is a one-time, deep fertilization technique for corn sowing? A: One-time deep fertilization technology for precision mechanized sowing of corn is an advanced corn planting technology. It uses the 2BQF-2 precision seeder to seed a single-seed corn seed and broadcast it to the soil according to the position of agronomical requirements. , And according to the amount of one-time deep chemical fertilizer planting techniques. One-time fertilization refers to the fact that chemical fertilizers are applied to the soil in depth according to agronomic requirements in order to achieve nutrients at different stages of the crop and meet the nutritional needs of the corn during the growth and development stage. The long-term fertilizer deep application breaks the traditional farming procedures and combines The closure of chemical herbicides reduces the number of artificial seedlings and manual weeding, saves excessive labor input, increases the utilization rate of fertilizers, and achieves the goal of increasing grain production and increasing farmers' income. 2. What preparatory work should be done before mechanical sowing? 3. What are the requirements for mechanical precision seeding? A: First, the sowing method: the use of precision seeder for precision seeding. Second, the amount of sowing: sowing size determined mainly based on seed size, seed viability and the degree of determination of the planting, can be calculated according to the following formula: hectare sowing amount (kg) = per hole grain number of plants per hectare thousand grains weight (g) Third, sowing depth: The sowing depth should be determined according to the soil type and temperature, current climate conditions and sowing techniques. Under normal conditions, the appropriate depth of sowing for the corn is 2.5 to 4.0 centimeters (the vertical distance between the surface and the seed after repression), in sandy lands and arid areas. And the year of drought should be appropriately deepened to ensure that the seeds are sowed on wet soil. Fourth, line spacing requirements: Mechanical sowing line should be straight, consistent line spacing. Within a 50-meter length range, the straight-line deviation is less than 2 cm, and the adjacent row spacing difference between the playing frames is less than 4 cm. 5. Repression after sowing: timely repression after sowing, to create appropriate soil compaction for crop growth, enhance soil conservation capacity, and help seed germination, is one of the important measures to ensure seedlings, Miao Qi, Miao Zhuang. 4. What precautions should be taken when precision seeding field operations? 5. What are the prospects for the promotion of the 2BQF-2 precision seeder? Answer: The application of 2BQF-2 precision seeder can save 2 kilograms of seed per acre without artificial seedlings, saving 0.3 man-days for working hours, realizing deep fertilization, fully increasing the utilization rate of water and fertilizer by 10 to 15 percentage points. With seedlings and seedlings, seedlings can grow 25 kilograms of corn per acre. The use of precision seed drills can also increase work efficiency and increase planting speed. The first-step operation is flexible and reduces labor intensity. It is of great significance to promote the industrialization, scale, serialization, and modernization of agriculture in our city. It is an inevitable trend in the new situation and has a wide range of popularization and application prospects.

A: First, soil tillage operations. Tillage quality is the basis for precise seeding. Through years of tests, it has been shown that the depth of cultivation should be consistent with the same depth, without recultivation and no ploughing, and that the land should be well-ordered, the ground should be level, the soil should be finely crushed, the coverage should be strict, and the weeds should not be exposed. After the soil is ploughed, it will be done in a timely manner. Second, seed selection and seed processing. The mechanical precision sowing has higher requirements on the quality of seeds, and selects high-yield and high-quality varieties suitable for the local natural conditions. Seed purity of 97%, strong germination potential, germination rate of more than 98%. Seed grains should be uniform, no damage, sun drying, coating, magnetizing treatment and so on before sowing. The seeds are best magnetized twice and sown within 24 hours of treatment.
A: First, the hand and the hand of the agricultural implement must closely cooperate. The hand of the farm hand constantly observes the sorting and rowing of the fertilizer to prevent the leakage of the seed and the leakage of the fertilizer. Second, pay attention to the amount of fertilization in the seed and fertilizer tanks. If it is found that the seedlings and fertilizers of a trip are not satisfied, they should be added in time so as not to waste time in the middle. Third, if you use a suction seeder for sowing, the fan speed should not flicker. 4. During the operation, it is forbidden to reverse the vehicle and turn it without lifting the implement so as not to damage the components.
