1953年,前华东农业科学研究所特用作物系与农业化学系合作,开始进行棉花生理及生化的研究,主要内容有三个部分:(一)研究早熟早衰生长势弱的棉株与迟熟迟衰生长势旺的棉株的矿物营养及有机营养的分析比较:(二)摘心整枝以及光期长短对于棉株有机营养积累与运转影响;(三)不同棉种及品种类型对有机营养积累的特点。第一部分:研究早熟早衰生长势弱与迟熟迟衰生长势旺的棉株矿物营养与有机营养的比较分析。(1)1953年用岱字棉15号,分别种在两种不同肥力的土地上。瘦地在四月中旬播种,6月上旬现蕾,8月下旬已至吐絮尾期。株高不足二尺,下部结铃率高,中上部早已脱力,结铃低。8月上中旬叶色变黄,下旬已枯落,代表生长势弱的棉株。肥
In 1953, before the East China Institute of Agricultural Sciences special crop and agricultural chemistry department, began to carry out cotton physiological and biochemical research, the main contents of three parts: (a) to study the premature premature aging weak cotton plant late late Analysis of mineral nutrition and organic nutrition of cotton plants with growing vigor: (B) the influence of inpping pruning and the length of light on the accumulation and operation of organic nutrition in cotton plants; (3) the accumulation of organic nutrition in different cotton varieties and varieties Features. Part I: Study on mineral nutrition and organic nutrition of cotton plants with weak growing and late growing and weak growing. (1) In 1953 Dai Dai cotton No. 15, were planted in two different fertile land. Sowing in mid-April sowing, early June bud, late August has been to the end of Tuowei. Plant height of less than two feet, the lower part of the bell rate is high, the upper part of the already off the hook low. Leaf color on the yellow mid-August, the late litter, on behalf of weak growing cotton plant. fat
