What is the one-time deep fertilization technology for corn mechanized precision seeding?

Maize mechanized precision seeding One-time deep fertilization technology is an advanced corn planting technique, which uses a 2BQF-2 precision seeder to carry out single-grain corn seeding into the soil according to the position required by agronomy, and The mechanized planting technique of chemical fertilizer is applied in one shot at a time. One-time fertilization means that the fertilizer is applied into the soil at a time according to the agronomic requirements to reach the nutrients of the crop at different stages, satisfying the nutrient requirements of the corn growth and development stage, and the long-acting fertilizer once and for all breaks the traditional farming procedure, and at the same time combines The chemical herbicide is closed, which reduces the number of artificial seedlings and manual weeding, saves too much labor input, improves the utilization rate of fertilizer, and achieves the goal of increasing grain production and increasing farmers' income.

What are the requirements for mechanical precision seeding?

First, the seeding method: using precision seeding machine for precision seeding.

Second, the amount of sowing: the amount of sowing is determined mainly according to seed size, seed viability and planting metrics, can be calculated according to the following formula: hectare planting amount (kg) = number of grains per hole × hectare plant × 1000 grain weight (g)

3. Seeding depth: The sowing depth should be determined according to soil type and temperature, climatic conditions and sowing techniques in the current year. Under normal conditions, the suitable sowing depth of corn is 2.5~4.0 cm (the vertical distance between the surface and the seed after repression). Sandy land, arid areas and dry years should be appropriately deepened to ensure that the seeds are planted on wet soil.

Fourth, line spacing requirements: mechanical sowing lines should be straight, line spacing is consistent. In the range of 50 meters in length, the linear deviation is less than 2 cm, and the difference in the line spacing between the broadcast frames is less than 4 cm.

V. Post-cast suppression: timely suppression after sowing, creating suitable soil compaction for crop growth, enhancing soil conservation capacity, and facilitating seed germination, is one of the important measures to ensure seedlings, seedlings, and seedlings.

What preparations should be made before mechanical precision sowing?

1. Soil tillage and land preparation. The quality of cultivated land is the basis of precision sowing. Through years of experiments, it has been shown that the depth of ploughing should be consistent, no ploughing, no ploughing, and the ground should be neat, the ground should be flat, the soil should be finely shredded, and the weeds should be covered. After the soil is deep ploughed, the land is adjusted in time.

Second, seed selection and seed processing. Mechanical precision seeding requires high quality of seeds, and selects high-yield and high-quality varieties suitable for local natural conditions. The seed purity is 97%, the germination potential is strong, and the germination rate is above 98%. The seed granules should be uniform and without damage, and should be sun-dried, coated, and magnetized before sowing. Seed magnetization is best twice and is sown within 24 hours of treatment.

What are the precautions when using precision seeding in field operations?

First, the machine hand and the farmer's hand must work closely together, and the farmer's hand often observes the seeding and fattening conditions to prevent leakage and leakage.

Second, pay attention to the amount of fertilizer in the seed and fertilizer boxes at any time. Once it is found that it does not meet the schedule and fertilizer amount of one stroke, it should be added in time to avoid wasting time by adding seeds and fertilizer to the middle of the ground.

Third, if sowing with a gas suction planter, the fan speed should not be high or low. 4. During the operation, it is strictly forbidden to reverse the vehicle and turn without lifting the agricultural implement to avoid damage to the machine.
