How to skillfully manage late-season wheat? These technical points must be mastered

Ensure sufficient soil moisture and base fertilizer. For late-season wheat, never rush to sow by seizing moisture; on the premise of ensuring adequate soil moisture, apply heavy base fertilizer, and where conditions permit, apply 3-5 cubic meters of high-quality farmyard manure per mu; at the same time, according to yield requirements, mix 2/3 of the total nitrogen, phosphorus and potassium chemical fertilizers invested throughout the growth period with farmyard manure, spread them on the surface and plow them into the soil.

Choose the right variety and increase the seeding rate. Late-season wheat is suitable for semi-winter varieties, which can be selected according to local conditions. At the same time, determine the actual number of days of late sowing according to local autumn temperatures. Generally, it is advisable to increase the seeding rate by 0.5 kg for each day of delayed sowing, and never blindly increase the seeding rate, so as to prevent seed waste and also avoid excessive density that leads to lodging and yield reduction later.

Cover with farmyard manure before winter to ensure the wheat seedlings survive the winter. Late-season wheat emerges slowly, the seedlings are weak and have poor resistance, and are prone to freezing damage before overwintering. Where conditions permit, cover with 2-3 cubic meters of crushed farmyard manure per mu to ensure the wheat seedlings overwinter safely. After that, combined with measures such as intertillage and loosening the soil, it can also supplement certain nutrients for @#@245@#@ strong seedlings before winter; at the same time, it also provides effective base fertilizer for the next crop.

Strengthen early spring management. During spring management, increase temperature and preserve soil moisture, and delay watering for greening. Late-season wheat is sown late, and the accumulated temperature before winter is insufficient. The focus of early spring management is to increase temperature and preserve soil moisture, prevent the ground temperature from dropping, and delay watering for greening. The main measures are: combining harrowing and rolling, alternating shallow and deep intertillage, promoting early greening of wheat, preserving pre-winter tillers, striving for early spring tillers, and ensuring the number of ears per mu.
