Detailed Explanation of Key Points and Methods of Wheat Planting Technology

Deep Plowing and Fine Turning, Applying Sufficient Base Fertilizer

For a field with an average yield of 400 kg per mu, apply about 10000 jin of farmyard manure, 20-50 kg of ammonium bicarbonate, and about 50 jin of dipotassium phosphate. Experts say: "Do not neglect soil fertilizer in favor of chemical fertilizer, neglect base fertilizer in favor of topdressing, or neglect phosphate fertilizer in favor of nitrogen fertilizer. Phosphate fertilizer can promote early maturity and control ineffective tillering. On the basis of deep plowing and fertilizing, harrow and level the soil; harrowing breaks large clods into smaller ones, and leveling breaks the clods into pieces." In order to eliminate underground pests (white grubs, wireworms, cutworms, etc.), soil disinfection should be carried out together with land preparation, generally using methyl powder at 2-3 jin per mu.

Select Good Varieties, Treat Seeds with Chemicals

Choose wheat varieties suitable for planting in the local area. Before sowing, the seeds should be sun-dried to increase enzyme activity and improve the germination rate. For seeds without coating, chemical seed treatment should be carried out. Generally, for 100 jin of seeds, mix 3 liang of 75% 3911 emulsifiable concentrate or 2 liang of 50% phoxim emulsifiable concentrate with 7-8 jin of water, pile them in the shade for 6 hours, and then sow.

Sow at the Right Time, Plant at Reasonable Density

How can a suitable sowing period be determined? This depends on the variety, the temperature, and the soil fertility. As for the variety, winter varieties come first and spring varieties later, subject to the variety description, with fewer leaves first and more leaves later. As for temperature, for winter varieties an average daily temperature of about 16°C is suitable. As for soil fertility, poor land first and fertile land later. "Sow in high mountains at White Dew, sow on plateaus at Autumn Equinox, and 10 days after Autumn Equinox sow on flat plains." Within the suitable sowing period, seize the time and shorten the sowing period. Reasonable dense planting means controlling a reasonable population structure, properly handling the contradiction between population and individual plants and the contradiction between more ears and larger ears, and making full use of soil fertility and light energy to achieve high and stable yields. The sowing rate should be determined according to the requirements in the wheat variety description and the sowing time and soil fertility conditions.
