摘 要: | 通过5年来对亩产500kg以上(600kg)小麦综合配套技术体系的研究得出:冬小麦亩产600kg的地块较亩产500kg的麦田土壤肥力显著提高,保肥供肥能力明显增强;基本苗多穗型品种以8~12万苗为宜,大穗型品种以14~16万苗为宜;重追拔节肥,补施挑旗肥;全生育期浇3~4次水,后期以延长功能叶片存活时间,提高光合能力,增加粒重为目的采取有利措施,最终可获得亩产600kg产量水平

Integrated Culture Techniques of 9-ton Grain Yield Per Hectare in Winter Wheat |
| |
Abstract: | Five-year studies on culture techniques to get 9 tons of wheat grain per hectare showed that if we intend to get the give yield,we must significantly increase hte fertility of soil,guarantee the essential seedlings at 1,200,000-1,800,000 plants for multispike varieties and at 2,200,000-2,500,000 plants for macrospike varieties per hectare Furthermore,we must pay more attention to fertilization at jointing and flagging stages,and give 3 or 4 irrigations in whole growth and development period |
