倒伏是进一步提高小麦产量的关键限制因素。常言道,“麦倒一把草。”倒伏不仅造成小麦大幅度减产,而且在农业劳动生产率大幅度提高的今天不利于机械套种(玉米)及收获。要想从根本上解决小麦倒伏问题,必须从裁培措施上下功夫。(1)大力推广小麦精播、半精播技术,适当减少播种量(适播小麦,亩基本苗以8—12万为宜)。(2)平衡施肥(重视磷、钾肥的
Lodging is a key limiting factor in further increasing wheat yield. As the saying goes, “wheat pours over the grass.” Lodging not only caused a sharp reduction in wheat production, but also detrimental to mechanical intercropping (maize) and harvesting at a time when agricultural labor productivity increased dramatically. If we want to fundamentally solve the problem of wheat lodging, we must work hard on the measures of reducing cultivation. (1) Promote wheat precision sowing, semi-sowing technology, appropriate reduction of sowing (suitable for sowing wheat, mu basic seed to 8-12 million is appropriate). (2) balance fertilization (emphasis on phosphorus, potassium fertilizer
