This year (2012), the returning green period of wheat is delayed by 5 to 7 days from the normal year, which is not conducive to the early growth of wheat, and may delay the wheat heading period and shorten the grouting time. Experts believe that the spring management of wheat should promote the formation of soil capillaries by repression, so that the deep soil moisture rises, nourishing the root growth. At the same time, reducing the evaporation of water through sketching and raising the temperature of the soil will promote the return of green wheat. Where conditions permit, it is strongly recommended that mechanized repression be used to play a comprehensive role in making up for cracks, lifting the soil, increasing temperature and promoting seedling growth. Experts also suggested that localities should be classified and guided according to different seedling conditions. A class of wheat fields with high soil fertility levels should be controlled by seedlings to increase the ratio of tillers and spikes, and promote the development of large spikes and grains. During the jointing stage of wheat, topdressing watering, mu recovery urea 16 to 18 kg. The focus of the management of the second type of seedlings is to consolidate the tillering before winter, properly promote the spring tillering, increase the rate of tillering and tilling, and top-dressing and watering in the initial stage of wheat recovery, and combine 15 to 17 kg of urea with watering. This year, the area of ​​the three types of seedlings in Hebei Province is small, and the spring topdressing of this type of wheat field is carried out in two separate stages. The first time the fertilizer is applied for watering in the returning green stage, 5-7 kg of urea is applied and the appropriate amount of diammonium phosphate is used to consolidate the delivery before winter. Promote spring delivery and increase the number of mu ears; the second time in the middle of the jointing, combined with watering Mushi urea 8 to 10 kg, increase the number of grains per ear. Experts suggest: After the return of green wheat, the ability to resist cold has declined. The most effective measure to prevent cold weather is to water before cold waves arrive. After the occurrence of late spring and winter disasters, we must promptly remediate, seize the time to apply topdressing nitrogen fertilizers, promote early-onset seedling growth, and increase the percentage of spikes for small tillers, which is generally about 10 kilograms per urea. Timely cultivating, raising ground temperature, and promoting root development. China Seed Network The fresh and natural taste is always attractive to people.

To this end, wheat experts put forward:
The author learned from the wheat spring management meeting held in Lucheng on March 17 that the low temperature in early spring this year delayed the return of green crops by five to seven days compared to the normal year, which is not conducive to the early growth of wheat, and thus affected. The time of wheat ear differentiation may delay the heading date of wheat and shorten the grouting time. To this end, wheat experts made recommendations to suppress repression and promote early onset of seedling growth.
