“农丰——891”植物促长素(以下简称“891”)主要成分为鳌合钛。近几年来,在全国12个省、市近40万亩农田,多种作物上应用有较明显的增产效果。为了明确“891”植物促长素对培育水稻壮秧、防止水稻烂种烂秧的作用,进一步为生产应用提供理论依据,我们进行了系列试验。目的在于探讨“891”植物促长素对水稻种子生理活性及幼苗生理效应的影响。 “Nongfeng - 891” plant auxin (hereinafter referred to as “891”) main component of chelated titanium. In recent years, nearly 40 million mu of farmland have been cultivated in 12 provinces and cities across the country, and the application of various crops has obvious effects of increasing yield. In order to clarify the role of “891” plant growth auxin in cultivating rice seedlings and preventing the rotten seedlings of rice, and further providing theoretical basis for production and application, we conducted a series of experiments. The purpose is to explore the effects of “891” plant auxin on the physiological activity of rice seeds and their physiological effects.
