一、壮秧的意义 我省水稻尤其是双季稻,秧田期占全生育期的1/4～1/3,占营养生长期的一半左右。所以,秧苗素质对插秧后的生长发育和产量影响极大。壮秧是丰产的基础,培育壮秧是夺取水稻高产的重要措施之一。 二、壮秧的的生育效应 壮秧的标准是什么,很难作出简单的回答。因为秧苗可分为小苗、中苗和大苗,还有嫩秧、嫩壮秧、壮秧、老壮秧等。不同类型的秧苗对壮秧的具体要求不尽相
First, the significance of strong seedlings Provincial rice, especially double cropping rice, seedling period accounting for the whole growth period of 1/4 to 1/3, accounting for about half of vegetative growth period. Therefore, the quality of seedlings after transplanting growth and yield significantly affected. Strong seedling is the basis of high yield, seedling cultivation is one of the important measures to capture high yield of rice. Second, the strong effect of seedling seedling seedling what is the standard, it is difficult to make a simple answer. Because seedlings can be divided into small seedlings, seedlings and seedlings, as well as tender seedlings, tender strong seedlings, strong seedlings, seedlings and other old strong. Different types of seedlings on the specific requirements of strong seedlings not phase
