尿素做小麦口肥引起烧籽烧苗,是小麦生产中急待解决的问题。小麦播种早生育期短,苗期需要充足的速效养份,所以施化肥做口肥,是夺取小麦高产的重要措施之一。尿素是我省的主要氮肥品种,约占全省氮肥总量的百分之七十到八十。所以必然要有相当数量的尿素做小麦口肥施用。近几年来,尿素做小麦口肥产生了严重地烧籽烧苗问题,造成种子的浪费和大幅度减产。因此,有些单位禁止用尿素做口肥,使小麦增产受 Urea fertilizer made of wheat fat burning seedlings, wheat production is an urgent solution to the problem. Wheat sowing early growth period is short, seedling need sufficient available nutrients, so fertilizer to make fat, is one of the important measures to capture high-yield wheat. Urea is the main nitrogenous fertilizer variety in our province, accounting for about 70-80% of the total nitrogen fertilizer in the province. So there must be a considerable amount of urea to do the application of wheat fat. In recent years, urea fertilizer to produce a serious wheat seedlings burning seedlings problem, resulting in a waste of seeds and a substantial cut. Therefore, some units prohibit the use of urea as fertilizer, so that wheat yield by
