杂交水稻在我县大东公社南严大队已试种了两年.1977年在中心生产队试种90亩,平均亩产1158.7斤,比常规水稻每亩增产308.7斤,其中40亩高产田,亩产达1386.5斤.1978年在不同劳力、茬口、肥力水平的10个生产队试种646亩,平均亩产1081斤,比常规稻每亩增产309—322斤,其中中心生产队166亩杂交稻平均亩产1208斤.两年试种结果表明,在现有条件下,无论早茬晚茬、肥茬薄茬,杂交稻都比常规稻显著增产.现就高产栽培中的几个问题,谈谈自己的看法.
Hybrid rice in the county Dadong commune Nan Yan brigade has been tried for two years in 1977 in the center of the production team test 90 acres, the average yield 1158.7 kg, 308.7 kg more than conventional rice yield per mu, of which 40 acres of high yield fields, Mu yield of 1386.5 kg.In 1978, 10 production teams with different labor, stubble and fertility levels tested 646 mu with an average yield of 1081 kg, an increase of 309-322 kg per acre compared with conventional rice, of which 166 mu The average yield per mu 1208 kg of rice .Two years of planting results show that under the existing conditions, regardless of the early crop stubble, stubble, stubble hybrid rice than conventional rice significantly increased yield .In the high yielding cultivation of several problems, Talk about your own opinion.
