Seeds should be dried for 1~2 days before sowing. It is good for water absorption after sowing, enhance seed coat permeability and seed enzyme activity. Seed dressing with new high-fat film before sowing can keep warm, moisturize and swell. Improve seed germination rate and make seedlings strong. Repel underground pests and isolate viral infections. It can also be mixed with a seed coating.
Sowing at the right time When 5 cm of ground temperature is stable at 10 °C ~ 12 °C, sowing, the depth is consistent, to ensure that the whole seedling is broadcast. If the planting is too early, the ground temperature is low, the germination of the corn is slow, and the seed rot is easy to occur, and the seedling cannot be produced normally; if the planting is too late, the maturity period will be postponed and the yield will be affected.
Scientific management intensive cultivation, leveling the land, deep ploughing the land before sowing, flattening and tidying, uniform ridges and appropriate suppression. Sowing should be done in depth and consistency to ensure that the seedlings are fully seeded. The soil sowed strictly adheres to the six-character standard of “墒, å¹³,é½,æ¾,碎,净â€, and deep application of base fertilizer, mastered at 15 cm, the mouth fertilizer should be separated from the seed, and applied to the seed 3 to 5 cm below. Avoid burning and burning due to shallow fertilization.
After pests and seedlings are released from the soil, they are easily damaged by pests. In areas with heavy pests, soil treatment should be carried out. Spraying and controlling should be carried out with highly targeted agents in combination with new high-fat membranes. Poisoning of highly toxic pesticides can be carried out. Poisoning pesticides are Low toxicity, low toxicity pesticides are slightly toxic. Control the volatile and volatile pesticides, prevent the rainwater from scouring, reduce the dosage per acre by half, and improve the control effect by multiple times.
The application amount and concentration of the herbicide herbicide used safely must be applied strictly in accordance with the instructions for use to avoid phytotoxicity due to large application rate and high concentration.
