一、秃尖缺粒产生的原因1、品种自身的原因玉米品种之间存在很大差异,一般来说,早熟品种和稳产品种,对光、温、水反应迟钝,籽粒灌浆速率快,结实性好,一般不秃尖缺粒。而晚熟品种,增产潜力也较大,对光、温、水反应敏感,籽粒灌浆速率比较慢,一旦遇到气候不正常年份或栽培管理不当,就会发生秃尖缺粒现象。当然,有一些品种介于二者之间,前期由于营养生长和生殖生长不协调,后期库源关系不协调,不利于籽
First, the reasons for bald spiked particles 1, the reasons for the varieties themselves There is a big difference between maize varieties, in general, precocious varieties and stable varieties, light, warm water, slow response, fast grain filling rate, strong Good sex, generally not bald sharp lack of grain. The late-maturing varieties, yield potential is larger, sensitive to light, temperature, water sensitive, grain filling rate is relatively slow, in case of unfavorable climate or cultivation and management of improper, there will be bald sharp lack of grain phenomenon. Of course, there are some varieties in between the two, the early due to unnatural vegetative and reproductive growth, the late library source relationship is not coordinated, is not conducive to the seeds
