为探索粮棉双高产的新途径,我们1975—1979年连续五年进行了小麦麦后直播棉花两熟连作试验。试验结果表明,实行麦棉两熟连作,小麦可增产30％左右,直播棉亩产皮棉多数在130斤左右,高的可达160斤以上;在1978年伏秋特大干旱条件下,平均亩产128.5斤。但与相同条件下的麦林套种棉相比,一般减产15％左右(表1)。
In order to explore a new way to produce high yield of grain and cotton, we conducted two-crop cotton continuous-flow continuous-cropping experiment after wheat and wheat for five consecutive years from 1975 to 1979. The results showed that wheat and cotton two crops continuous cropping, wheat yield increase of about 30%, live cotton yield lint most of the 130 kg, up to 160 pounds or more; in 1978 autumn drought conditions, the average yield per mu 128.5 pounds. However, compared with the same conditions, Meiling cotton, the general reduction of about 15% (Table 1).
