There are techniques for late sowing wheat to create high yield.

Because of the late sowing time of late sowing wheat (@ # @ 245 wheat sown after the middle of October, generally known as late sowing wheat), it is difficult to achieve complete, strong and uniform seedlings, so it is not easy to get high yield. But if properly managed, high production is also possible.

The main results are as follows: (1) it takes 10 to 15 days for late sowing wheat with sufficient basic fertilizer from sowing to emergence, which shortens the growth time before winter and weakens the growth time of wheat seedlings in the soil. Late sowing wheat must apply sufficient base fertilizer, 3500 kg of high-quality soil fertilizer, 40 kg of ammonium sulfate, 50 kg of superphosphate and 10 kg of potash fertilizer per mu.

(2) to apply wax fertilizer to late sowing wheat to prevent frost injury in winter, 2000-3000 kg of high-quality pigsty fertilizer plus 10-15 kg of urea per mu was evenly applied to the wheat row.

(3) in the period of returning to green, according to the physiological characteristics of late sowing wheat, we should hoe in time according to the soil moisture in order to increase the ground temperature and promote the early development of seedlings. In the period of returning to green, there is no topdressing and watering, so as to ensure the rise of ground temperature, promote root increase and tiller, and cultivate strong seedlings. If the soil fertility is poor, the population is insufficient or the soil moisture is poor, you can open ditches or planing holes in the turning green, apply nest fertilizer or irrigate chemical fertilizer and water to promote wheat growth and alleviate drought.

(4) the wheat at the stage of re-application of fertilizer and water is sensitive to fertilizer and water, which is the key period for the management of late sowing wheat. Sufficient fertilizer and water is beneficial to tillering and increasing the number of grains per spike. At this time to heavy fertilization, generally combined with watering per mu of standard nitrogen fertilizer 20-30 kg. In the land with insufficient phosphate fertilizer, 20 kg of phosphate fertilizer can be applied per mu.

(5) the jointing and booting fertilizer was applied 20 kg urea and 5-10 kg potassium dihydrogen phosphate per mu, and other micro-fertilizers could be combined with the control of aphids and powdery mildew. Late sowing wheat fields with good soil fertility, sufficient base fertilizer and large population should be postponed to topdressing and watering at jointing stage.

(6) the management of single-stalk cultivation in wheat fields with single-stalk cultivation should, according to its technical requirements, strictly control fertilizer and water during turning green and rising stage, and then re-fertilize and water when jointing to the tip of flag leaves.
