水稻螟虫主要是在稻蔸内越冬,而三化螟又以稻兜为唯一的越冬场所,因此 毁灭稻蔸是消灭越冬螟虫的根本办法。毁灭稻根的办法很多,如秋耕秋种、冬耕冬种(秋耕冬耕结合拾毁稻蔸)、春季灌水入田、提早春耕等,实行这些办法都能把潜伏在稻蔸内的越冬螟虫杀死。但这些办法都只能用在秋收後的休閒田,对於种有红花草的晚田,既不能秋耕、冬耕,也不能提早春耕(提早春耕影响红花草的青草产量和肥效),并且红花草不但不能停种,而且隨推行三变还必须日益广大。因此,如何处理红花草田内的稻蔸是一个很重要的问题。 Rice stem borers are mainly wintering in the rice paddies, and the rice stem borer is the only place for overwintering. Therefore, the destruction of paddy rice paddy is the fundamental way to eliminate wintering stem borers. There are many ways to destroy rice roots, such as autumn planting autumn, winter farming winter planting (winter plowing combined with picking up wild rice), spring irrigation into the field, early plowing and so on, the implementation of these methods can be lurking in the rice paddy in the winter Stem borers kill. However, these methods can only be used in the leisure fields after the autumn harvest. For the late field with the red flowers and grass, neither the autumn and winter plowing nor the early spring plowing (early plowing affects the grass yield and fertilizer efficiency of the safflower grass) Red flowers not only can not stop farming, but with the implementation of three changes must also be increasingly widespread. Therefore, how to deal with red rice straw in the field is a very important issue.
