Corn management after autumn
At present, corn is in a small trumpet period, a large trumpet period, and a tasseling period, reminding farmers to strengthen field management according to actual conditions to reduce disasters and ensure production.
1. Grasp the drainage and disperse the Linfen
At present, the crops are in a rainy period, and the drainage and diversification efforts are increased on the depressions to clear the drainage ditch and eliminate the water in the field. Land plots with no clear water should seize the favorable timing of the rainy period, enhance soil permeability and improve the crop rhizosphere environment.
2, timely replenishment of quick-acting fertilizer
Most of the corn is in the period from the big bell to the heading stage. It is the key period for corn growth. The absorption capacity of corn roots is reduced. The quick-acting nitrogen fertilizer such as urea should be properly added to promote the growth and development of corn. The plot of land with a yield of about 500 kg per mu can be applied with 15-20 kg of urea per acre and about 10 kg of potassium sulfate. Fertilization should be carried out by ditching or using mechanical sputum to avoid spreading. It is necessary to prevent premature aging of corn early, and apply about 7.5 kg of urea per mu in the grain filling period. Prevent lodging
3, do a good job of pests and diseases control
Focus on the prevention and control of worms, corn borers, mites and other pests and brown spot, large spot disease, rust and other diseases. The armyworm can be sprayed with 50% phoxim 1000 times solution. Ear worms such as corn borer can be controlled by 90% trichlorfon 800 times droplets. Corn gluten can be sprayed with 50% chlorpyrifos 8-10 grams per acre or 10% imidacloprid 10-15 grams per acre plus 45 kilograms of water spray. Brown spot, large spot disease, Curvularia leaf spot can be sprayed with 50% carbendazim 500 times solution, and rust can be controlled by spraying 20% ​​of rusting emulsifiable concentrate with 75-100 ml per acre.
