受省科委委托,我们承担了“鄱阳湖区棉花良种区域化及高产优质栽培技术模式应用与示范研究”课题。1989年,在永修县虬津乡虬津村进行了200亩连片高产试验示范,平均亩产皮棉95.5公斤,比前五年(1984～1988)平均产量(79公斤/亩)递增20.8％,增收99.0元/亩;比1988年增产64.2％;比同村非示范片(78.6公斤/亩)增产16.7％,增收50.7元/亩。取得了较好的经济效益和社会效益。现将主要技术经验总结如下。
Commissioned by the Provincial Science and Technology Commission, we assume the “Poyang Lake area of cotton varieties and high-yielding cultivation of high quality cultivation technology model application and demonstration” project. In 1989, a trial of 200 mu of contiguous high-yielding trial was carried out in Xijin Village, Xijin Township, Yongxiu County with an average yield of 95.5 kg of lint, an increase of 20.8% over the previous five years (1984 to 1988) with an average yield of 79 kg / mu 99.0 yuan / mu; an increase of 64.2% over 1988; an increase of 16.7% over the non-demonstration film in the same village (78.6 kg / mu), an increase of 50.7 yuan / mu.
