Wheat planting technology

Deep ploughing and fine ploughing and applying sufficient base fertilizer

In general, about 10000 jin of farm manure, 20 kg of ammonium bicarbonate and 50 jin of dipotassium phosphate should be applied to the field with a yield of 400kg per mu. Experts said: "We cannot ignore that soil fertilizer depends on chemical fertilizer, base fertilizer depends on topdressing, and phosphate fertilizer depends on nitrogen fertilizer." Phosphate fertilizer can promote precocious maturity and control ineffective leafing. On the basis of deep ploughing and fertilization, raking is smooth, raking makes the large clods smaller, and ploughing makes the clods broken. " In order to eliminate underground pests (grubs, golden needles, land tigers, etc.) combined with soil preparation to carry out soil disinfection, methyl powder is generally used, 2 kilograms per mu.

Select the improved varieties and mix the seeds with chemicals

To select wheat varieties suitable for planting in this area, the seeds should be exposed to the sun before sowing, so as to increase the activity of enzymes and improve the germination rate. The uncoated seeds should be mixed with chemicals. Generally, 3911 EC or 50% phoxim EC should be added to the seeds without coating, and the seeds should be sown after stacking in the shade for 6 hours.

Sowing at the right time and reasonable close planting

What is the appropriate sowing time? It depends on the variety, the temperature and the soil fertility. Look at the variety, first winter and then spring, according to the variety description, first less leaves and then more leaves. According to the air temperature, the daily average temperature is about 16 ℃ for winter varieties. Look at the soil power, thin land first and then fertile land. "White Dew planted high mountains, the Autumn Equinox planted plateaus, and then planted Pingchuan 10 days after the autumn score." In the appropriate sowing time, we should seize the time and shorten the sowing time. Reasonable close planting is to control the reasonable population structure, deal with the contradiction between population and individual, the contradiction between large ear and large ear, and make full use of soil fertility and light energy to achieve high and stable yield. The sowing rate should be determined according to the requirements of the wheat variety description, sowing time and soil fertility.
