一、试验目的与效果: 为了改变我县两熟连作棉花面积大,产量低的落后状况,我们从78年开始到80年先后三年进行了棉花两熟连作栽培试验与示范工作,取得了较好的效果。尤其是八一、八二年在县科委和省棉所支持下,又将油后连作棉花采用化学化高产栽培新技术,效果更为理想。实现了省工、省肥、省本、高产之目的。八一年试验地亩产皮棉163.8斤,今年三个点亩产分别为183斤、192.2斤、210.3斤。超过一般早播棉花产量,而且早熟优质,每亩可省工4—7个,省肥15％,降低成本10％左右,事实证明采用化学化栽培新技术,是提高棉花单产和劳动生产率的一个简而易行见效快的新途径。
First, the purpose and effect of the experiment: In order to change the two counties in our county with a large area of cotton, low yield and backward conditions, we have from 78 years to 80 years has three consecutive years of cotton two-cropping cultivation experiment and demonstration work, and made more Good results. In particular, August 1, 1982 in the county committee of science and technology and the support of the provincial cotton, cotton and even after the oil as a chemical and high-yield cultivation of new technologies, the effect is even more satisfactory. Achieve the provincial labor, provincial fertilizer, the province, high-yield purposes. In 1981, 163.8 kilograms of lint per mu was produced. Three mu per mu were 183 kilos, 192.2 kilos and 210.3 kilos this year respectively. More than normal early-sowing cotton production, and precocious quality, per acre can save 4-7 months, 15% of fertilizer, reduce the cost of about 10%, it turned out that the use of chemical cultivation of new technologies is to improve cotton yield and labor productivity A quick and easy way to get things done.
