在推广麦、稻、稻三熟的耕作制中,麦后早稻的早熟高产在全年生产中占有十分重要的位置;产量约占全年产量的45％,有时高达50％以上;其成熟时间的早迟,直接关系着晚稻的栽插时间,影响着晚稻的安全齐穗,左右着晚稻产量的高低。在麦后早稻的整个生育期内,具有对高产十分有利的气象和生物因素:前期低温威

In promoting the three-cropping system of wheat, rice and rice, the early maturity and high yield of early wheat after heading wheat occupies a very important position in the annual production; the output accounts for about 45% of the annual output, sometimes up to 50% or more; and the maturity time Sooner or later, is directly related to the planting time of late rice, affecting the safety of late rice at full capacity, affecting the level of late rice production. In the whole growth period of wheat after the early rice, with high yield is very favorable meteorological and biological factors: pre-low-temperature Wei
