川东高温伏旱区再生稻大面积单产不高，年度间收获面积不稳，主要原因是中稻收割前后高温伏旱制约再生芽正常伸长和出苗。1990～1995年我县开展了再生稻抗旱发苗关键技术的探讨，进行了多点试验和大面积示范，取得了显著成绩。1995年全县蓄留再生稻有收面积8．6万亩，平均亩产2 The main reason for the large area yield of ratoon rice in the high temperature and VAS region in eastern Sichuan was not high, and the area harvested during the year was not stable. From 1990 to 1995, the county carried out a discussion on the key technologies of drought resistance and seedling of ratooning rice, carried out multi-point experiments and large area demonstration and achieved remarkable results. In 1995 the county has received regenerative rice harvest area of ​​86000 mu, the average yield 2
