明确和掌握水稻高产预测预控技术是许多水稻研究工作者致力奋斗的目标.一九七八年,我们以同安县委在新民公社祥桥大队组织的杂交水稻丰产片为基地,从水稻田间生育关键时期的生态诊断出发,预测和控制水稻群体向高产目标发展,取得了肯定的效果.试验以杂交水稻“四优二号”为供试品种,早季试区面积78.38亩,平均亩产1025斤;晚季连试159.60亩,平均亩产1112斤.其中,核心试验田7.70亩,早季平均亩产1210斤,晚季平均亩产1408斤,两季合计亩产2618斤,过了三个《纲要》.实践证明,水稻高产的生态表征既然
It is the goal of many rice researchers to work hard to clear and master the technology of predicting and controlling the yield of high-yield rice.In 1978, based on the high-yielding hybrid rice crop that was organized by Tong’an County Committee in Xiang-brigade of Xinmin commune, Period ecological diagnosis to predict, and control the development of high-yielding rice population to achieve a certain effect.Experimental hybrid rice “Siyou 2” as the test varieties, the early season test area of 78.38 acres, the average yield of 1025 pounds ; Late season even test 159.60 acres, an average of 1112 kg per mu, of which 7.70 acres of core experimental field, the average yield of early morning 1210 kg, the average yield of late 1408 pounds, two seasons a total of 2618 pounds per mu, after three “ Outline. ”Practice has proved that since the ecological character of rice high yield
