【摘要】 <正> 栽培技术措施受地区条件的严格限制,各地生产条件又千差万别,不提高到规律性认识就不能扩大应用。兹就个人二十几年工作所及,整理分析了东北地区群众栽培技术经验与有关的试验研究资料,提出我国北方春大豆某些技术措施的综合高产技术运用规律。本文远不能概括所有大豆高产技术规律,对于综合规律的研究这仅仅是探索的开始。更多还原

【Abstract】 Our researches have laid down four fundamental rules of high-yielding cultural technique of soybean and their morphological characteristics. According to these rules and morphological characteristics of the soybean,we may greatly raise our activity in culture practice and enhance the repetition of the efficiency of cultural technique.1.The rule of choosing cultural technique according to the temperature and water conditions.2.The rule of choosing suitable ecotype variety according to the temperature, light, water and fertility conditions.3.The relationship of the unity of opposites between technical measurements and varieties and its application.4.The promotion and inhibition relationship betweon various technical measurements and its application,5.According to the three morphological characteristics under high-yield and the two key periods in high-yielding cultivation, we can divde the life cycle of soybean in different periods to adapt the suitable technical measurement.6.The reliability of these four fundamental rules and the three morphological characteristics have got proved in our culture practice.更多还原
