宁夏银川灌区在七十年代种稻一般是在4月底5月上旬育秧,由于冷害频繁,造成产量低而不稳。1980年以来,推广4月22日以前育秧,产量增加较快。但此时大渠尚未放水,育秧用水缺乏,限制了产量的进一步提高。为了解决这个问题,我们从1982～1984年连续三年进行了保墒旱育秧试验示范,并获得成功。其技术
Yinchuan Irrigation in Ningxia in the seventies species of rice is generally the end of April early May seedlings, due to chilling injury, resulting in low and unstable output. Since 1980, the promotion of seedling planting before April 22, the output increased rapidly. However, at this time, the drains have not yet been drained, and the lack of water for seedling raising has limited the further improvement of output. In order to solve this problem, from 1982 to 1984 for three consecutive years we conducted drought-tolerant seedling cultivation experiments, and success. Its technology
