Skillful management of wheat in late crop

The soil moisture and fertilizer should be adequate. The late stubble wheat must not rush to sow the soil moisture, under the premise of ensuring the soil moisture, re-apply the base fertilizer, conditional application of high-quality farm manure 3 square per mu; at the same time, according to the yield demand, 2% of the total N, P and K chemical fertilizer invested during the whole growth period and farm manure were mixed and scattered on the surface and into the ground.

Select the right variety and increase the sowing quantity. Late stubble wheat is suitable for semi-winter varieties, which can be selected according to local conditions. At the same time, the actual days of late sowing are determined according to the local autumn temperature. Generally speaking, it is appropriate to increase the sowing amount by 0.5 kg per day, and must not blindly increase the sowing rate, so as not to cause seed waste and lead to lodging and yield reduction in the later stage of excessive density.

Cover farm manure before winter to ensure that wheat seedlings survive the winter. The late stubble wheat emerges slowly, the seedling weak resistance is poor, and it is easy to be damaged by freezing before overwintering. Conditionally cover 2-3 mu of mashed farm manure to ensure that wheat seedlings survive the winter safely. Since then, combined with measures such as ploughing and loosening the soil, it can also supplement certain nutrients for strong seedlings before winter, and at the same time, it can also provide effective base fertilizer for the next crop.

Strengthen the management of early spring. Spring pipe should increase the temperature and preserve soil moisture, and postpone pouring back to green water. The late stubble wheat was sown late, and the accumulated temperature was insufficient before winter. the focus of early spring management was to increase temperature and preserve soil moisture, prevent soil temperature from falling, and postpone pouring back to green water. The main measures are: the combination of rake and rolling, the alternation of shallow and deep ploughing, promoting the early turning green of wheat, keeping the tillers before winter, fighting for early spring tillers, and ensuring the number of ears per mu.
