1958年江西都昌县农业科学研究站在国营苏山垦殖场第三营第二连,进行了棉花根外追硼的试验,增产效果较为显著,试验处理比对照增产10.6%。试验地是去冬休闲地,面积为1.24亩,沙壤土质,试验分处理和对照,二次重复,四个小区,每小区面积为3分,试验小区按十字排列法排列,供试品种是岱字15号。在试验中,处理小区和对照小区栽培操作完全相同,另外对处理小区进行了三次根外追硼的试验处理,各次的浓度和
In 1958, Jiangxi Duchang County Agricultural Science Research Station in the second phase of the third battalion of the State-owned Su Shan Reclamation Field, carried out a trial of cotton chasing the boron outside the root, yield more significant effect, the experimental treatment yield 10.6% more than the control. The experimental site was a winter recreation area with an area of 1.24 mu. Soil samples of sandy loam soil were processed and controlled in duplicate. Four plots were plotted with an area of 3 plots per plot. The plots were arranged in a crisscross pattern, Word number 15. In the experiment, the cultivation area of the treatment plot and the control plot were exactly the same. In addition, the test treatment of three times of the root-outside-chasing the boron was carried out on the treatment plot. The concentration and
