Detailed Explanation of Key Corn Planting and Management Techniques
Summary Seedling stage management: From emergence to the jointing stage, it is necessary to check for and fill in missing seedlings in a timely manner, remove weak seedlings and keep strong ones. Field management at the ear stage: From jointing to tasseling, 3 rounds of intertillage can be carried out when the seedlings grow to 4-5 leaves, when the seedlings grow to about 30cm, and before jointing. Large

Timing of foliar fertilizer spraying on corn: is it related to the amount of water?
Abstract When corn suffers from pests and diseases, or when the soil is too acidic, too alkaline, or too high in salinity, and during the full fruit stage, after plants suffer from gas damage, heat damage, and freeze damage, foliar fertilizer can be sprayed. Whether corn foliar fertilizer spraying is related to the amount of water: generally, for root-outer spraying, it is necessary to add

Corn Leaf Spot Disease Pictures and Treatment Methods
Abstract Agricultural control: remove diseased leaves from the lower part of diseased plants, and pay attention to drainage in low-lying plots. Timely fertilization: apply 10-20 kg of chemical fertilizer from the jointing stage to the tasseling stage of corn. Chemical control: use 15 g of 30% hexaconazole suspension concentrate, 30 g of 10% Bacillus subtilis, 50% carbendazim wettable

How to Get the Timing and Chemical Choice Right for Corn Growth Regulation
Abstract: Timing of chemical growth regulation in corn: the growth retardant is applied at the 8-10 leaf stage of corn, that is, the early jointing stage of corn. Common types of chemical growth regulators for corn: corn vigorous-growth agent, ethephon, mepiquat chloride, chlormequat, paclobutrazol, amino acid fresh lipid, etc. Generally, a mixed agent is used to achieve a combination of fast-acting and long-lasting effects, and it is less affected by weather, with outstanding growth control and yield increase, and the chemical regulation time can be moved earlier, with no toxicity and no side effects.
