据不完全统计,宁夏引黄灌区亩产千斤以上的水稻只占40%左右,亩产800斤左右的仍占35%,还有25%左右亩产在600斤以下。为此,我们于1982～1983年到青铜峡蒋顶公社银光大队蹲点,从调查水稻低产原因入手,与农户签订技术承包合同,推广增产技术。在示范田上取得显著的效果,并得到迅速推广。 According to incomplete statistics, only about 40% of rice produced in Ningxia Yellow River irrigated area with a yield of more than one kilogram can still account for 35% of the total yield of about 800kg, and about 25% of the total yield is below 600kg. To this end, we went to Qingtongxia Jiang Ding commune Silver Brigade from 1982 to 1983, from the investigation of low-yielding rice causes, and farmers signed a contract of technology to promote production technology. Significant results have been achieved in the demonstration fields and have been rapidly promoted.
