春小麦化控稀植高产技术可行性分析

Feasibility Analysis on Chemical Control and Less Plant Population High - yielding Practices in Spring Wheat

近年来春小麦播种量越来越大,种植成本越来越高,出现了产量高,但经济效益并不明显的现象.通过对春小麦化控稀植技术的分析,证明了运用春小麦化控剂Ⅰ号,可以促进春小麦早分蘖、多分蘖,并能促进足够数量的分蘖成为有效分蘖,达到既可减少播量,又能保证产量并提高经济效益的目的,将是我国东北春小麦种植方式的一场变革.

In order to explore the feasibility of chemical control and less plant population in wheat, several years study in different locations was investigated, and a chemical control agent named Nol CCA was patented, the results show htat No. 1 CCA can stimulate early tillering and form more tillers, and also could enhance the ratio of fertile tillers, combined with other practices, the cultivation technique with less plant density but higher final grain yield could be achieved.
