冬去春来,麦苗返青,从营养生长逐渐进入生殖生长阶段。这一时期是争穗多、穗大,增加粒数,提高结实率和增加千粒重,夺取丰收的关键阶段。因此,一定要根据年前麦苗长势和春季生育特点,结合土壤、气候等条件,加强管理,争取增产增收。主要管理措施是:一、巧施肥。对群体较大、麦苗健壮的高产田块,应掌握“苗期促、返青控、拔节攻”的施肥原则,少施或不施返青肥。重施拔节孕穗肥,控叶蹲节,防止倒伏。对因缺肥造成的落黄早衰和晚播迟发的弱苗,要巧施返青肥,重施拔节肥,猛攻 Winter to spring, barley green, from vegetative growth gradually into reproductive growth stage. This period is a crucial stage for spawning more spikes, increasing spikes, increasing grain numbers, increasing seed setting rate, increasing grain weight and seizing good harvests. Therefore, we must strengthen the management according to the characteristics of wheat seedlings grown in previous years and the characteristics of spring fertility in combination with the conditions of soils and climates, and strive to increase production and incomes. The main management measures are: First, clever fertilization. For larger groups, high-yielding wheat seedlings plots, should have “promote seedling, green control, jointing attack ” principle of fertilization, with or without application of green manure. Re-apply jointing booting panicle, leaf control squat festival, to prevent lodging. Because of the lack of fertilizer caused by falling yellow premature aging and late broadcast of weak seedlings, to Qiaoxian return green manure, re-apply fertilizer, stormed
