在杂交水稻高产栽培中,根据杂交水稻主茎不同叶龄期采取相应的高产栽培措施,对夺取杂交水稻高产具有十分重要的作用。我们根据叶龄模式原理,结合本县杂交水稻高产栽培实践,初步摸索了我县杂交火稻各组合主茎总叶片数及变化规律,探讨了根据杂交水稻叶龄期采取高产栽培措施的方法。1 杂交水稻主茎总叶片数
In hybrid rice high-yielding cultivation, it is very important for high-yielding hybrid rice to take high yielding cultivation according to the different leaf ages of main stem of hybrid rice. Based on the principle of leaf age and the practice of high-yielding cultivation of hybrid rice in this county, we initially explored the total number and variation of main stems of hybrid rice in our county, and discussed the methods of high-yielding cultivation according to the leaf age of hybrid rice. 1 hybrid rice main stem of the total number of leaves
