1979年,新疆作物学会和新疆农科院粮作所联合倡导在全疆开展水稻小面积(一亩以上)高产竞赛,竞赛中亩产达1,600斤以上的品种有五个,即78—1、矮丰2号、沙交5号、7303、7511—2—5—2.为了更好地认识这些品种,使其在生产中发挥更大作用,我们于1984年将这些品种在米泉种植并观察.种植土壤为黄胶土,肥力中上,前茬水稻,井水灌溉.供试的五个品种均采用塑料薄膜育秧移栽,4月19日播种,5月28日移栽,小区面积3米~2,顺序排列,不设重复,行长3米,行距6寸,株距3寸,5行区,单本移栽,亩施基肥(大粪干)700斤,6 In 1979, the Xinjiang Crop Institute and the Xinjiang Academy of Agricultural Sciences jointly advocated grain production in Xinjiang to carry out small-scale rice (more than one acre) high yield contest, the race of more than 1,600 pounds per mu varieties of five, namely 78-1, Afefeng 2, Shajiao 5, 7303, 7511-2-5-2. In order to better understand these varieties and make them play a greater role in production, we planted and observed these varieties in Miquan in 1984 The planted soil was yellow plastic soil, middle and upper fertile, pre-stubble rice and well water were irrigated.The tested five varieties were all transplanted by plastic film seedling, sown on April 19, transplanted on May 28, and the plot area 3 Rice ~ 2, arranged in order, without duplication, the governor 3 meters, row spacing 6 inches, spacing 3 inches, 5 rows of areas, single transplanting, mu base fertilizer
