一九八三年冬,织金县从云南大理县引进粳型“滇榆一号”良种8000斤,种在海拔1040～1850米地区的稻田,共种240亩。除海拔1040米的地区比当地品种减产外,其它地区均获得增产。特别在海拔1400米以上的地区比种毛毛谷、冷水谷成倍增产。这充分说明了引种是成功的。一、引种的条件和可行性织金县有稻田17万多亩,分布在海拔1040～1850米的地区,水稻常年总产量徘徊在5000万斤左右,平均亩产300斤左右,是我省水稻单产最低的一个县。造成水稻单产低的主要原因,是海拔1400米以上地区的6万多亩稻田,历来种毛毛谷、冷水谷,单产很低,仅200来斤。要提高织金县的水稻产量,必须改变这些地方的
In the winter of 1983, Zhijin County imported 8,000 kg of japonica-type “Dian-yu-1” elm seeds from Dali County, Yunnan Province, and planted 240 hectares of paddy fields in areas of 1,040 to 1,850 meters above sea level. In addition to 1040 meters above sea level than the local varieties of production cuts, the rest of the region have been increased. Especially in the area above 1400 meters above sea level than Mao Mao Valley, cold valley doubled yield. This fully demonstrates the introduction is successful. First, the introduction of the conditions and feasibility of Weaving County has more than 170,000 mu of paddy fields, located in 1040 ~ 1850 meters above sea level, the annual output of rice hovers around 50 million pounds, an average of about 300 kilograms per mu yield, is our province rice The lowest yield of a county. The main reason for the low yield of rice is that more than 60,000 mu of paddy fields are above 1400 meters above sea level. To increase the rice production in Zhijin County, these places must be changed
