What are the technical measures for high-yield corn cultivation?
Summary Selection of plot: choose a plot with flat terrain, deep soil layer and loose texture. Seed selection: do not use seeds from the previous year. Base fertilizer: apply farmyard manure, calcium superphosphate, urea, potassium fertilizer and zinc fertilizer in a single banded application into the field. Sowing: carry out in February-March, with a sowing density of

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

When to plant waxy corn? Detailed planting techniques and timing
Summary Variety selection: Choose varieties with a short growth period, wide adaptability and strong disease resistance. Planting density: row spacing of about 1 m, hill spacing of 0.33-0.38 m, two plants per hill. Sowing time: spring waxy corn is sown at the end of February or in early March, autumn waxy corn is sown in late July.

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.

When is the best time to apply corn growth regulator?
Abstract: You can choose to spray the growth regulator when the corn has 6-12 leaves. You can spray the upper leaves of the plant, but do not spray the whole plant. This can effectively promote full corn kernels and increase the number and weight of kernels. Growth regulator is one of the methods for high corn yield, and it is convenient and effective.

A Detailed Explanation of Corn Seedling Raising Methods and Key Technical Points
Summary Seedbed seedling raising: spread nutrient soil into a seedbed surface, then scatter the seeds on the seedbed surface and cover with soil; when transplanting, lift the seedlings together with the soil. Nutrient cup seedling raising: use cup-shaped containers or a pot-making machine to make the nutrient soil used for raising seedlings into nutrient cups, then sow and raise seedlings in the nutrient cups; after the seedlings are grown, transplant them together with the cups. Soilless seedling raising: use wooden boards or other containers to make seedling trays, and raise seedlings in the trays by hydroponics.

When is the best and safest time to apply post-emergence herbicide to corn seedlings?
Abstract: The suitable time to apply herbicide is after 6 PM in the evening. Because the temperature is lower and the humidity is higher at this time, the liquid will remain on the weed leaves for a longer period, allowing the weeds to fully absorb the herbicide components, which helps improve the weeding effect and also improves

How to master corn watering timing more scientifically
Summary Watering at sowing: soil moisture is 65-75% of field capacity. Watering at jointing stage: soil moisture is 60-65% of field capacity. Watering at tasseling stage: soil moisture is 70-80% of field capacity. Watering at grain filling stage: soil moisture is 70-75% of field capacity.
