Study on the Cultivation Technique of Lu Ning No.1 of Surpass High-yield Summer Soybean with Country Tries High Grade

Through the cultivation of Lu Ning(JN96-2343),the bean 73,97-1 breed(departments),the high yield kind of quality JN96-2343 which has the potential of increasing production had been selected,and the organism's habits,physiology index and high yield potential had been determined.Through the surpassing high yield and replaying nature cultivation in 2000～2001,per unit area yield respectively 4 684.8 and 4 506.0 kg,was obtained.With the identification of the expert in homeland,the kind of quality had reached "the country 9th Five-Year Plan" key problems index,which was 4 650.0 kg/hm2 per unit area yield.The kind of quality had become the first breed of the replaying nature cultivation of the country high yield material,and was the only breed of surpassing high yield and replaying nature in Huanghe and Huaihe River area.
