冬小麦亩产600kg综合配套技术研究

Integrated Culture Techniques of 9-ton Grain Yield Per Hectare in Winter Wheat

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。

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
