粳型杂交稻“滇杂25”是云南农大用“滇农1号”作不育系,用“南25(V—4)”作恢复系杂交培育而成的。1981年我县农艺师王柏村同志从云南农大引进,经过3年在海拔1,000米的大阳、石门和600米的鸡鸣、路阳等公社栽培结果,表现良好,1983年全县已种植2,400多亩。通过三年的实践,干群一致认为“滇杂25”具有产量高、生育期短、抗寒、耐旱性强、经济性状好等优点。①产量高。1981年在太阳公社栽培1.1亩,4月27日播种,7月21日齐穗,8月21日成熟,全生育期114天,平均亩产854.5斤,比当地“黄粘”增产36％。1982年在太阳公社栽培51亩,也获得增产。1983在石门公社的柳林、茶元、石门3个大队,31个
Japonica hybrid rice “Dianza 25” is Yunnan Agricultural University with “Diannong 1” as a sterile line, with “South 25 (V-4)” as a restorer line of hybrid breeding. In 1981, County Agronomist Wang Baicun introduced from Yunnan Agricultural University, after 3 years at an altitude of 1,000 meters in the sun, Shimenshan and 600 meters of cock, Luyang and other communes cultivation results, performed well, in 1983 the county has planted 2,400 Mu. Through three years of practice, the cadres and the masses agreed that Dianza 25 possesses the advantages of high yield, short growth period, cold resistance, strong drought tolerance and good economic performance. ① high yield. In 1981, 1.1 hectares were cultivated at Sun Commune, sown on April 27, and spiked on July 21 and mature on August 21. The whole growth period was 114 days, with an average yield of 854.5 kg per mu, an increase of 36% over the local “yellow sticky.” In 1982, 51 acres were cultivated in the Sun Commune and production was also increased. 1983 in Shimen commune Liulin, Chayuan, Shimen three brigades, 31
