我场地处哀牢山下红河西岸低热河谷,全场种植双季稻1,500亩,单产连续三年过“吨粮”。1976年。试种麦—稻—稻、豆—稻—稻、肥—稻—稻,初步获得成功,其中221亩麦稻三熟田,小麦亩产444斤,早稻亩产1,110斤,晚稻亩产926斤,实现了三熟亩产过“三纲”。还有9亩高产试验田。小麦亩产721斤,加上早稻亩产1,081斤、晚稻亩产900斤,创造了三熟亩产2,702斤的高产纪录。双季稻地区两热变三热,是栽培制度上的一项重大改革,涉及问题较多,其中尤以三熟作物品种的合理搭配最为重要。据我们试验,小麦品种中“墨波”早熟,全生育期仅118—120天,但产量较低,增产潜力有限,且易感白粉病;“墨巴65”虽比“墨波”迟熟10—12天,但比“墨波”增产近二成,且增产潜力大。水稻品种中“0—8”、“通红矮”、“广白矮”早熟,高
My site is located in Ailaohe River Ailaohejihehe valley, the audience planted 1,500 acres of double cropping rice, yield for three consecutive years over the “tons of grain.” 1976. Among them, 221 mu of wheat and three paddy fields, 444 kg of wheat per mu, 1,110 kg of early rice per mu and 926 kg of late rice per mu, were successfully planted for wheat, rice, rice, beans, rice, rice and fertilizer, Realization of three acres of mu production over the “three programs.” There are 9 acres of high yield test field. 721 pounds of wheat per mu, plus 1,081 pounds of early rice per mu, 900 tons of late rice per mu, creating a yield of 2,702 cats per mu. Double cropping two hot areas into three heat, is a major reform of the cultivation system, involving more problems, especially the three varieties of crops with the most reasonable match. According to our experiments, the “Mo Bo” wheat variety is premature, with a full-term growth period of only 118-120 days, but the yield is low and the yield potential is limited and susceptible powdery mildew; 10-12 days, but more than “Mo Bo” yield nearly 20%, and yield potential. Rice varieties “0-8”, “reddish”, “Guangbai short” premature, high
