目前双季晚稻由于底肥不足,加上前期气温高,肥料分解快,在进入幼穗分化后,明显缺肥,结果穗小粒少,产量不高,1975年我们在三江公社彭鲁大队五小队大田中进行了施用穗肥试验。结果施穗肥的田比对照增产18.6%。试验田前作为早稻品种繁殖田,早稻7月26白收割。二晚插前每亩施枯蚕豆梗500斤(折纯 N8.0斤),过磷酸钙50斤,碳酸氢铵10斤作耖口肥(折纯 N1.7斤)。试验田未翻耕,只用手扶拖拉机横直扎一遍后平田插秧。双晚品种为鄂晚三号,6月16日播种,7月29日插秧,8月3日每亩追尿素20斤,8月
At present, the double-season late rice due to lack of base fertilizer, coupled with high pre-temperature, fast decomposition of fertilizers, after entering the spike differentiation, obviously lack of fertilizer, the results of spikelets less, the yield is not high, in 1975 we Sanli commune Pengru brigade five squad Tanaka conducted a panicle test. Results Shizhuofu yield 18.6% more than the control. Field trials as early rice breed fields, early rice July 26 white harvest. Two nights before the insertion of mutton per kilogram bean 500 kg (pure N8.0 kg), 50 kg of superphosphate, ammonium bicarbonate 10 kg for fat mouth (pure N1.7 kg). Experimental field is not plowing, only tractor crossbar bar straight after planting Hirata transplanting. Double night for the E night on the 3rd, sowing June 16, July 29 transplanting, August 3, 20 acres of urea recovery per acre, August
