一、前言“九二○”是一种强烈的植物生长刺激素,在许多作物上应用,已取得了肯定的增产效果。水稻是我们最主要的粮食作物。“九二○”在水稻上的应用经过了一年多来群众性试验研究的结果,出现了不少增产的苗头,并且在大部分试验田中取得了增产的效果。然而,由于农业生产的影响因素极其复杂,因此,“九二○”在水稻上的应用效果表现得不很一致。要使施用“九二○”成为水稻生产上的稳定的增产措施,就必须搞清“九二○”施用后对水
I. Preface “920” is a strong plant growth hormone that has been applied to many crops and has achieved positive yield-increasing effect. Rice is our main food crop. Application of “920” to Rice After more than a year of mass pilot study, a lot of signs of increasing yield have emerged and the effect of increasing yield has been achieved in most experimental fields. However, due to the extremely complicated factors affecting agricultural production, the application effects of the “920” on rice have not been very consistent. In order to make the application of “920” a stable increase in rice production, it is necessary to find out whether water
