三、谷子成苗的生理生态谷子成苗主要是指形成壮苗,因为壮苗是谷子高产的基础。据试验分析,壮苗指标与穗重之间呈显著的正相关,相关系г=0.8785。实践证明,谷怕三荒(苗荒、草荒、子荒),谷打三壮(壮苗、壮秆、壮穗)。特别是平川地区,常常由于蹲不住苗,荒苗减产十分严重。壮苗的长相,应该
Third, the millet seedlings physiological and ecological millet seedlings mainly refers to the formation of strong seedlings, because strong seedling is the basis of high yield of millet. According to the experimental analysis, there is a significant positive correlation between strong seedling index and panicle weight, the correlation coefficient г = 0.8785. Practice has proved that Valley afraid of three shortage (Miao shortage, grass shortage, child shortage), Valley hit three strong (strong seedlings, strong stalk, strong spike). Especially in Hirakawa area, often due to squatting seedlings, wasteland reduction is very serious. Strong seedling looks, it should be
