一九八四、八五年,我们进行了免耕机械旱直播栽培配套技术(品种、播期、播量、播种方式和化学除草等)的试验,总结如下。试验田前茬是免耕小麦,品种为“复虹30”、“嘉农14”、“寒丰”、“早单八”等。六月上旬播种,播量每亩12～13斤。先施随籽肥(化肥),后用免耕机条播。播后灌水,田干后喷施“除草醚”,二叶期喷“杀草丹”,追施分蘖肥、长粗肥(饼肥)和穗肥。人工拔草二至三次,其它管理与翻耕移栽稻同。试验结果与分析 (一)产量与效益 1.增产显著:据两年在嘉西、唐行、曹王的五个生产队的试验,共七组29.39亩,结
In 1984 and 1985, we conducted experiments on the techniques of direct-seeded cultivation of no-tillage machinery (variety, sowing date, seeding rate, sowing method and chemical weeding, etc.). Tillage before the experimental field is no-tillage wheat, the varieties of “complex rainbow 30”, “Jiunong 14”, “cold abundance”, “early single eight” and so on. Seeding in early June, sowing 12 ~ 13 pounds per acre. First with the seed fertilizer (fertilizer), after tillage machine with sowing. After sowing, watering, dry field after spraying “weed”, two leaves spray “kill grass Dan”, topdressing tillering, long crude fertilizer (cake fertilizer) and the panicle. Artificial weeding two or three times, other management and tillage transplanting rice with. Test results and analysis (A) yield and benefits A significant yield increase: According to two years in Jiaxi, Tang line, Cao Wang’s five production team test, a total of seven groups of 29.39 acres, knot
