摘要
黑龙江省水稻倒伏危害较重,造成倒伏的原因主要是不适合的综合栽培技术导致水稻抗倒伏能力下降所致。黑龙江省水稻倒伏应划分为茎折倒、茎弯倒和浅根倒3种类型。生产中应根据造成这3种类型倒伏的原因,有针对性地采取防御倒伏发生对策。综合防御对策主要有选用抗倒伏性品种、提高整地质量、穗数不能过多、控制水稻长势和预防早衰等。同时提出了需要深入探讨的问题。
Rice lodging is a serious problem in Heilongjiang province, the main cause of rice lodging is that una- daptable comprehensive cultivation technique lead to the anti-lodge ability descent. There are three lodging types in Heilongjiang province,they are stem fold down, stem bend down and shallow roots down. We should take pertinence defensive countermeasure ~ccording to the three types. Choosing lodging resistance variety,im- proving soil preparation quality, controlling spike number, controlling growth vigor and preventing premature senility were the comprehensive defensive countermeasures. And the problems that need to be further discus- sion were put forward.
