在小麦生产中,大量实践证明,低产变高产和中产到高产(亩产800斤)一般都是适当增加每亩成穗数,而高产再高产,多数人认为增加穗重是关键,就目前我市高产麦田种植的郑引一号和郑州761小麦为例,应该主攻成穗数?还是主攻穗粒数或粒重?这是应该深入探讨课题之一,我们采取试验田和大田相结合方法对郑引一号进行了六年、对郑州761进行了四年成产三因素调查,现将结果进行整理分析,供商讨.一、产量构成三因素变化规律
In wheat production, a large number of practices have proved that low yield and high yield and middle class to high yield (800 kg per mu) are generally appropriate to increase the number of spikes per acre, while high yield and then high yield, most people think that increasing panicle weight is the key Cheng high yielding wheat fields planted Zhengzhou No. 1 and Zhengzhou 761 wheat, for example, should be the main number of spikes? Or the main spike grain number or grain weight? This is one of the topics should be discussed in depth, we have to test the field and field combination of Zheng Cited on the 1st for six years, Zhengzhou 761 for four years into the production of three-factor survey, the results will now be analyzed for discussion .A three-factor changes in production patterns
