我们从1975年开始试验稻田不耕翻,耙茬播种,1977年应用于生产。几年来,耙茬水稻小面积试验由600多斤提高到近千斤,比同等条件的翻耕地增产5.4—13%。大面积生产在600斤以上,不低于翻耕的。耙茬不翻耕的好处(一)田面易平碎,耕层结构好:在头年土地整平的基础上以重耙进行耙茬,可克服犁翻的堑沟和不平,保持田面的原有平度,土壤细碎,形成10厘米左右的疏松耕层,
We started in 1975 to test the rice fields do not plow, rake crop planting, applied to production in 1977. In recent years, the test of small area of harrowed stubble rice has been increased from 600 kilograms to nearly one kilogram, yielding 5.4-13% more than the same conditions of tillage. Large-scale production of more than 600 pounds, not less than plowing. Harrow stubble does not tillage benefits (a) the field of easy to break, tillage structure is good: the first year of land leveling on the basis of heavy rakes for stubble, plow trough can be overcome and uneven, keep the original A flat, soil crushing, the formation of about 10 cm loose plow,
