Wheat seedlings need to manage three types of seedlings

Wang Miao management Wang Miao is generally caused by factors such as good soil fertility, adequate fertility, good sensation, early sowing, and high density. For Wang Miao, which is caused by adequate fertilizer and good sensation, deep-medium cultivating methods should be adopted to cut old roots, promote new roots, regulate the absorption of nutrients, reduce spring delivery, prevent leggy, and promote the development of large pods. For Wang Miao, which is caused by excessive density or early sowing, the seedlings should be seeded in a timely manner to establish a suitable population structure so that individuals can fully develop. Where conditions permit, paclobutrazol can be used to control the length of the wheat seedlings. Generally, 15% paclobutrazol wettable powder 50 to 60 grams per mu is sprayed before wintering.
Weak seedling management Weak seedlings are mainly caused by factors such as late sowing, poor soil preparation, low soil fertility, and lack of sensation. For weak seedlings caused by low soil fertility and lack of lye, management should be strengthened to ensure early management and early watering, watering after topdressing, timely cultivating tillage, promoting root growth and tillering, and weakening the weak seedlings. Generally in the wheat 3-leaf stage, 5-7 kg of urea per mu, and 2500-3000 kg of farmyard fertilizer are mixed and applied. For the weak seedlings caused by late seeding, except for the severely defective plots, they are generally not watered, so as to avoid a drop in ground temperature, which is not conducive to the emergence of seedlings. For late-seeding and poorly-graded wheat fields, cultivating soil should be timely and 2,000 to 3,000 kilograms of organic fertilizer should be applied per acre.
Strong seedling management is not enough for the base fertilizer but good seedlings with good seedlings in the wheat fields should be supplemented with fertilizers to avoid the transformation of wheat seedlings into weak seedlings. If there is sufficient base fertilizer but there are serious running problems and there is a lack of strong seedlings in the wheat fields, the cultivator shall loosen the land and protect the earth. In severely-deficit seedlings, wheat fields should be filled with water and irrigated with water after cultivation. At the end of the fertility, good sensation, timely seeding seedlings of wheat, generally do not need to fertilize, as long as the cultivator.
