南充地区丘陵起伏,全区有40多万亩稻田由于位置高、无灌溉条件,成了等雨栽秧的望天田。我区夏旱频率为40％,即五年两旱。夏旱一来,望天田不是迟栽减产,就是等不到雨,栽不成秧而丢一季荒;或者栽一季迟红苕,成了全区水稻生产上的风险田、低产田。如何确保望天田稳产高产?过去我们曾经推行过改走旱路的办法,即将望天田的“麦—稻”两热,改为“麦/玉/苕”三熟,全年亩产虽可 Nanchong region hills and downs, the region has more than 400000 acres of rice due to the high position, no irrigation conditions, became rainy seedling Wang Tiantian. My area summer drought frequency of 40%, that is, five years two drought. In the summer drought, it is not late rice production reduction, that is, can not wait for the rain, can not afford to plant seedlings and throw a monsoon; or planting a late Chihiro, has become the risk of rice production on the field, low yield field. How to ensure a steady and high yield in the hope of Tiantian? In the past, we had once implemented a plan to change the way of removing the dry roads. We would like to see the two hotties of “wheat-rice” in Tian Tian be replaced by the three crops of “wheat / jade / chuan”
