各地早稻高产经验证明,适时早播,培育中苗壮秧是夺取早稻高产的重要措施之一。1980年我县早稻育秧,基本做到了适时早播、适量稀播、适当延长秧龄,以培育中苗壮秧,各批秧播期一般比历年提早5—7天,播量(每亩,下同)减少200—300斤。第一批秧多数在3月16—20日播种,播量一般200—300斤,秧龄30天以上,比历年长5天左右。第二批秧多在3月底以前播完,播量400斤左右。三熟田早稻多在4月5日左右播种,比历年提前3—5天。但有的地方过分强调“早”和“稀”,因此有部分田块在3月10—13日播种,有的田块播量只100斤左 High yield of early rice around the experience that early sowing timely, nurturing seedling strong seedling is one of the important measures to win high yield of early rice. In 1980, early rice planting in our county basically achieved timely sowing, moderate sowing, proper extension of seedling age, in order to cultivate seedling strong seedling, seedling sowing time is generally 5-7 days earlier than the calendar year, sowing rate (per acre, under The same) to reduce 200-300 pounds. Most of the first batch of seedlings planted in March 16-20, the general sowing 200-300 pounds, seedling age more than 30 days, about 5 days older than calendar. The second batch of seedlings and more sowing before the end of March, sowing about 400 pounds. Triad early rice and more sown around April 5, 3-5 days earlier than the calendar year. However, some places overemphasize “early” and “thin”, so some plots were sown on March 10-13, and some plots broadcast only 100 jin left
