研究和揭发播种密度与大豆品种特性及其他增产措施之间的关系,才能更好地贯彻执行“合理密植”。在生产中确定大豆播种密度时,必须考虑大豆的品种特性,栽培条件等因素,因为播种密度并不是孤立的、而是与栽培技术措施的各个方面都存在着内在的联系。因此,合理密植的幅度是依其他农业技术措施的改变为转移的。我们先后用“东农1号”和“东农4号”两个大豆品种进行了播种密度试验。这两个品种中“东农1号”大豆属于无限结荚类型的品种,分枝多,荚果分布在全株上;“东
To study and expose the relationship between planting density and characteristics of soybean varieties and other stimulation measures can we better implement “reasonable and close planting.” When determining the planting density of soybeans in production, the characteristics of cultivars and cultivation conditions of soybean must be considered, because planting density is not isolated, but is intrinsically linked with all aspects of cultivation techniques and measures. Therefore, the rationale for close planting is shifted by changes in other agricultural technologies. We have used “Dong Nong 1” and “Dong Nong 4” two soybean varieties were planted density test. The two varieties of “Dongnong 1” soybean belongs to the unlimited pod type varieties, many branches, pod distribution in the whole plant; "East
