多年的实践证明,“作物生长发育的化学调控”已在我国农业科学技术中占有一席之地,近10年我国水稻上应用多效唑技术便是一个鲜明的例证。它对促进水稻生产起了有益的作用。 一、多效唑培育水稻壮秧技术 我国长江中下游双季稻种植区,连作晚稻因受茬口限制,秧龄过长,同时又值夏季高温,秧苗生长迅速,移栽时苗体过大,移栽后败苗重,返青慢,
Years of practice have proved that “chemical regulation of crop growth and development” has a place in China’s agricultural science and technology. The application of paclobutrazol to rice in China in the past 10 years is a clear example. It has a beneficial effect on rice production. First, paclobutrazol rice seedling cultivation technology Mid-lower reaches of the Yangtze River in China double cropping rice, continuous cropping due to stubble restrictions, seedling age is too long, while the value of summer high temperature, rapid seedling growth, seedling transplanting too large, after transplanting Defeat seedling weight, turn green slowly,
