为探讨豫豆8号的需肥特点,于1989年对其植株氮、磷、钾吸收量、吸收速率、转化率及全株氮、磷、钾总量与密度的关系进行了试验研究,以便为大豆高产施肥提供参考依据。材料和方法供试品种:豫豆8号和中豆19。两品种均设每亩1.2、1.5、1.8和2.1万株四个密度,共8个处理。小区面积0.025亩,4次重复,随机排列。试验设在周堂镇民赵村西地,试验地土壤两合土,前茬小麦
In order to discuss the characteristics of fertilizer requirement for Yudou 8, the relationship between N, P, K uptake, absorption rate, transformation rate and the total N, P, K total density of plant was studied in 1989 so that Provide a reference for high yield fertilization of soybean. Materials and methods Varieties tested: Yudou 8 and Zhongdu 19. The two varieties are set at 1.2, 1.5, 1.8 and 21,000 strains per acre four density, a total of eight treatment. Community area of 0.025 acres, 4 times repeated random arrangement. The test is located in the village of Zhao Zhaotang West Zhou, two soil test soil, crop before the wheat
