Precautions when using corn no till seeder
1. Seed selection: tighten the sample of corn and select different varieties according to different soil, fertility and other conditions. The width of the sample is measured with a vernier caliper. The machine is precision sowing, and the sowing number can be adjusted according to needs. Generally, 2-3 seeds per hole are appropriate. Seeds should be selected from good seeds with full particles and high quality, with a germination rate of more than 95%, and the seeds should be coated
2. Fertilizer selection: granular fertilizer (urea, ammonium sulfate, compound fertilizer, etc.) should be selected for this machine. Powdery fertilizer is easy to agglomerate and has poor fluidity, which will affect the fertilization effect. Before sowing, the granular fertilizer should be checked, and the caking should be removed, so as not to block the fertilizer discharge pipe and affect the amount of fertilization. The appropriate amount of fertilization is 5-10kg per mu
3. Seeding operation: This machine can complete stubble breaking, ditching, seeding, fertilization and other operation procedures at one time. During seeding operation, it is advisable to sow seeds 5cm deep into the soil, apply chemical fertilizer 8cm deep into the soil, and apply seed fertilizer not less than 4cm. No missed sowing, no rebroadcast, consistent sowing depth, good soil coverage, and strict suppression
4. Spray chemical herbicides and insecticidal pesticides in a timely and appropriate amount. Spray one-time herbicides within 3 days after sowing, or use biocide herbicides at the 3-leaf stage of weeds. The investment range can be used for weeding (it is fair to affirm that the cost of energy storage projects is very important. Spray again after raining within 12 hours)
