为了探明棉花简化栽培的效应和技术 ,于1 999年进行了棉花简化栽培的田间试验。结果表明棉花简化栽培不影响生育进程 ,但通过增强棉花的长势和铃数 ,可使皮棉单产不减 ;同时通过减少整枝、中耕等管理环节的用工 ,使植棉的纯收入显著提高。在试验的基础上 ,文中提出了适合鲁西北棉区纯作棉花的简化栽培技术 In order to test the effect and technique of simplified cotton cultivation, a field trial of cotton simplified cultivation was conducted in 1999. The results showed that the simplified cotton cultivation did not affect the reproductive process. However, by increasing cotton growth and boll number, the lint yield could be reduced. At the same time, the net income of cotton planting was significantly increased by reducing the labor costs for the management of pruning and cultivating. On the basis of the experiment, this paper put forward a simplified cultivation technique suitable for cotton pure cotton in the northwestern Shandong Province
