广西每年7—9月份,甘蔗常受到台风暴雨的袭击,造成倒伏,使甘蔗的产量和含糖量都受到影响。所以,要切实加强防倒伏工作,其措施是:一、追肥。氮肥偏多是引起甘蔗倒伏的主要原因之一,故要氮、磷、钾肥配合施用。甘蔗伸长期,需肥最多,应追肥2次。第1次在甘蔗伸长初期(约6月中下旬)追施,每亩施碳铵20—25公斤或尿素12—15公斤、过磷酸钙15—20公斤、氯化钾 July to September each year in Guangxi, sugar cane is often hit by typhoon torrential rains, resulting in lodging, so that sugar cane production and yield are affected. Therefore, we must effectively strengthen the anti-lodging, the measures are: First, topdressing. Nitrogen is mostly caused by lodging of sugarcane one of the main reasons, it is nitrogen, phosphorus and potassium fertilizer with the application. Sugarcane elongation, the need for up to fat, top dressing should be 2 times. The first in the early elongation of sugarcane (about mid-late 6 months) topdressing, ammonium bicarbonate 20-25 kg per acre or urea 12-15 kg, 15-20 kg of superphosphate, potassium chloride
