本试验于1980—1982年在本院试验地进行,前2年供试品种是玛娜佩尔、满丝,1982年是满丝、强力米寿、强丰、高秧瓦尔特、早粉2号。照射的剂量分别是930拉特、2,790拉特、2,325拉特。剂量率分别是45拉特/分、30拉特/分,28拉特/分。以不照射的同品种为对照。播种前一天照射干种子,照射后加水湿润,次日播入温室苗床.3—4片真叶时移栽于冷床(阳畦)内,晚霜过后定植于露地。小区面积0.01亩,株距1.5尺,行距1.65尺.顺序对比排列,重复5次。亩施土羊粪6,000斤,过磷酸钙200斤为基肥,无追肥。整枝为单秆整枝,其它管理同一般大田。照射对产量和成熟期的影响主要如下.1.出苗较快 1981年3月18日照射的玛
This experiment was conducted in our hospital from 1980 to 1982, the first two years of test varieties are Manabel, full of silk, full of silk in 1982, strong Mishou, strong abundance, high seedlings Walter, early powder 2 . Radiation doses were 930 lats, 2,790 laces and 2,325 laces. The dose rates are 45 lates / minute, 30 lates / minute and 28 lates / minute, respectively. The same type of non-irradiated control. The day before sowing, the seeds were radiated and the plants were wetted with water after irradiation. The seedlings were sowed in the greenhouse the next day, and 3-4 leaves of true leaves were transplanted into the cold bed (Yangliu) and were planted in the open field after the night frost. Residential area of 0.01 acres, spacing 1.5 feet, row spacing 1.65 feet. The order of comparison, repeated 5 times. Mushi soil sheep manure 6,000 pounds, superphosphate 200 kg base fertilizer, no top dressing. Pruning single stump pruning, other management with the general field. The effects of irradiation on yield and maturity are mainly as follows: 1. Emergence of faster shoots on March 18, 1981
