1991年遇上大旱,大面积晚稻田无法及时下插,其中3565亩改种秋马铃薯,平均亩产鲜薯930公斤,比冬种马铃薯亩增64公斤。实践表明,改种秋马铃薯是抗旱夺粮的新途径之一。其主要栽培技术如下:1.选用良种。马铃薯的块茎具有一定的休眠期,秋季种植,除要重视品种的丰产性、适应性和抗病性外,更为重要的是选用休眠期短的品种。我们选用了近几年引进示范推广的冬种表现前期长势旺、结薯较早、块茎大、抗病力强、适应性广、产量高、休眠期较短的马铃薯良种“克新3号”。据农户苏常立改种的观察,8月24日播种,9月4日出苗,10月15日开始结薯,12月22日收获,鲜薯亩产1388公斤,折原粮亩产277.6公斤,单株最高鲜薯重1.4公斤,最大单薯重0.4公斤。
In 1991, a severe drought hit a large area of late paddy fields which could not be inserted in time. Of these, 3565 mu were planted with autumn potato, with an average yield of 930 kg of fresh potato and 64 kg of winter potato. Practice shows that the transformation of autumn potato is one of the new ways to drought-resistant food. The main cultivation techniques are as follows: 1. Selection of elite. Potato tubers have a certain period of dormancy, autumn planting, in addition to pay attention to the varieties of high yield, adaptability and disease resistance, more importantly, the selection of short dormancy varieties. We selected the introduction of demonstration and promotion in recent years, the early winter species performance of Mongolian, early potato tuber, tuberous, strong resistance, wide adaptability, high yield, short dormant potato varieties “Kexin 3” . According to the farmer Su Changli replant observations, sowing on August 24, September 4 emergence, starting October 15 tubers, December 22 harvest, fresh potato mu produce 1388 kilograms, fold the original grain mu produce 277.6 kilograms, plant The highest fresh potato weight 1.4 kg, the largest single potato weight 0.4 kg.
