为使棉花稳长多结,减少脱落,早熟高产,多收优质花,增加棉农收益,我县从1981年示范应用了缩节安、矮壮素等植物生长调节剂。四年来,先后组织了10个点的联合试验示范和推广,化控效果好,增产较显著,深受棉农欢迎。到1984年全县应用缩节安、矮壮素、棉长素、助壮素的面积达一万亩,占全县棉田面积的40％,一般增产10％以上,全县共增产63万斤。而且好花比例大,售价高于对照棉,获得增产增收的良好效果。无论大面积示范和小区试验比较,以上药剂用后,都能明显地控制株高,缩短棉株主茎和果枝节距,增加茎粗,减少脱落,加
In order to stabilize the cotton knot more, reduce shedding, early maturity and high yield, more quality flowers, increase cotton farmers income, my county from 1981, the application of reduced security, CCC and other plant growth regulators. In the past four years, a total of 10 pilot joint demonstration projects have been organized and promoted. The chemical control effect is good, the output is more significant, and it is welcomed by cotton farmers. By 1984, the county applied Shuan’an, CCC, cotton longan, help Zhuang Su an area of 10,000 mu, accounting for 40% of the county cotton area, the general increase of 10%, the county increased a total of 63 kg . And a good proportion of flowers, the price is higher than the control of cotton, access to a good effect of increasing production and income. Regardless of the large-scale demonstration and plot test, after the above-mentioned medicaments were used, the plant height could be obviously controlled, the pitch of main stems and fruiting branches of cotton plants was shortened, the stem diameter was increased, the shedding was reduced
