1997年的小区试验及大田示范结果表明 :简化栽培棉单位面积总成铃数、铃重等与常规栽培棉 (对照 )差异不显著 ,衣分显著低于对照。简化栽培棉皮棉产量为 1463.3kg/hm2 ,比常规栽培棉增产 5.4 % ,差异不显著 ;间作早玉米的简化栽培棉为 1456.7kg/hm2 ,比对照增产 4 .9% ,差异不显著 ,但多收一季玉米。在单株叶枝数 1～ 4个范围内 ,简化栽培棉单株叶枝数与单株成铃数呈显著或极显著正相关关系 ,但以带有 1～ 2个叶枝的棉株为构成产量的主体。简化棉和常规棉的丰产性、早熟性、纤维品质相当。但简化栽培棉省工、节本 ,净增产值达 1777.5元 /hm2 ,间作早玉米后 ,净增产值达 2 4 60元 /hm2 。简化栽培技术体系仍待进一步地配套、完善
The plots in 1997 and demonstration in Daejeon showed that there was no significant difference in boll number, boll weight, etc. between conventional cultivated cotton (control) and simplified cotton cultivars. The lint percentage was significantly lower than that of the control. The yield of simplified cotton lint cotton was 1463.3kg / hm2, which was 5.4% higher than that of conventional cotton cultivars, and the difference was not significant. The simplified cotton cultivation of intercropped early corn was 1456.7kg / hm2, increased by 4.9% compared with the control, but the difference was not significant Receive a quarter of corn. In the range of 1 ~ 4 leaves per plant, there was a significant or very significant positive correlation between the number of leaflets per plant and the number of bolls per plant. However, cotton plants with 1 ~ 2 leaf branches accounted for the highest yield main body. Simplify cotton and conventional cotton's high yield, precocity, and fiber quality. But to simplify the province of cotton cultivation, section, the net increase of 1777.5 yuan / hm2, Intercropping early corn, the net increase of 2,460 yuan / hm2. Simplified cultivation technology system still needs to be further matched and improved
