基本情况一九七七年早造我们进行了杂交水稻的高产试验,内容包括高产试验和多因子试验,高产试验采用杂交组合十个,多因子试验设肥料、组合、规格三个因素,试验田面积共16.67亩。试验田前作是冬种大坡油菜。本田施肥前取土样分析,全氮0.1467,全磷0.1510,全钾1.21,有机质0.318,PH值6.6,属土壤养分较丰富的粘壤土肥田。排水状况一般良好。历年高产试验均有较严重的稻纹枯病。冬种油菜于3月17日收获,茎秆不还田。用机干犁后灌水耙沤。基肥于第二次机耙前施放。3月28日插秧,全部采用撬秧带土移栽,拉线浅插。4月5日和4月12 Basic Situation Early in 2007, we made high yield test for hybrid rice, including high yield test and multi factor test, high yield test using hybrid combination of ten, multi factor test set fertilizer, combination, specifications of three factors, the experimental field area A total of 16.67 acres. Before the trial field is a winter species Dapeng rape. Honda soil samples taken before fertilization analysis, total nitrogen 0.1467, total phosphorus 0.1510, total potassium 1.21, organic matter 0.318, PH value 6.6, is a soil nutrient rich clay loam fertilizer field. Drainage condition is generally good. Over the years high yield test have more serious rice sheath blight. Winter rape was harvested on March 17, and stalks were not returned to the field. After the machine dry plow irrigation rake 沤. Base fertilizer is applied before the second rake. March 28 Transplanting, all with prized seedlings with soil transplanting, cable light inserted.
