近年来,不少棉花高产县反映铃轻籽瘪,对争取棉花高产、稳产、优质、低成本构成很大障碍。这个问题已引起普遍重视。大家正在研究主攻铃重的对策。为了进一步探讨这个问题,下面分别就有关铃重下降引起的后果、产生的原因及其解决途径这三方面,提出一些粗浅的见解。一、铃轻籽瘪派生出一系列问题从大面积考察情况看,大部分棉花高产县,历年棉花统算百铃重的平均数都不足350克,而且波动比较大,这是近年来为什么棉花产量上不去、产量不稳定的症结所在。现以江苏启东和河南新乡这南北
In recent years, many cotton high-yielding counties have shown that bell seed is deflated, posing a big obstacle for securing high yield, stable yield, good quality and low cost of cotton. This issue has caused widespread attention. We are studying the main bell countermeasures. In order to further explore this issue, the following are some of the superficial insights on the consequences caused by the decline in bell weight, the causes and solutions to these three aspects. First, the bell seed light deflated to produce a series of problems From a large area inspection situation, most cotton high yield counties, calendar years, the average number of cotton bolls weigh less than 350 grams, but the volatility is relatively large, which is why in recent years cotton Yield does not increase, the crux of the unstable output lies. Is now Qidong, Jiangsu and Henan Xinxiang this north and south
