When wheat is sown and emerged at the initial stage, if it is found that crops with insufficient seedlings and insufficient basic seedlings can differentiate seedlings, the following measures should be taken to prevent and control them. First, timely replanting to ensure that the whole seedlings, in the timely detection of seedlings after the emergence of wheat, seedlings are not homogeneous, resulting in serious shortage of broken wheat fields, to grab the early stage of emergence, with the same species of seeds for replanting. Second, replenishing and diluting wheat in the three-leaf period, the whole field is better, only a few places lack of nest, seedlings of the wheat field, can be taken in the Honda within the tightly packed thin strip soil transplant, after transplanting rooting Water method to make up seedlings. When transplanting, it is necessary not to press the heart to expose the white, bury the water after the cover is solid, and make up the appropriate fertilization material to facilitate the seedlings. Third, drought replenishment of seedlings due to drought, watering should promptly remedy, poured once a day, even for 3-5 days, to promote the normal growth of wheat seedlings, seedlings and more. For improper wounding due to pesticide application, water remediation should be given 2-3 times, and water should be used to loosen soil. Fourth, chase fertilizer to promote the emergence of more uniform for each nest, but the lack of basic seedlings of wheat can be grabbed during the period from the emergence of the three-leaf to fast-acting nitrogen fertilizer, Shi Shi Shi applied early Miaofei. It can promote the early delivery of childbirth, sub-distraction, and optimization of individuals, to achieve early winter strong and high yield. 5. If the mulching of the cover soil causes a lack of seedlings due to excessive seeding, some soil cover can be removed, combined with irrigation and cultivator, to improve soil ventilation and promote lateral root development. VI. Prevention and control of pests Wheat pests and diseases that often occur before winter are mainly root diseases and underground pests. Preventive measures should be taken in time to eliminate pests and diseases so that thin wheat seedlings can be turned into strong seedlings as soon as possible. VII. Preventing Salt Loss The wheat fields lacking seedlings caused by salt damage should be ploughed and rigged in time to reduce evaporation on the ground and prevent back-salt. The use of irrigation washing salt or trenching salt method to reduce soil salt content.
