| 摘 要： | 为研究间作条件下威芋3号的氮肥营养效应,采用田间试验方法,研究了薯玉传统间作模武、威芋3号与芸豆新间作模式(薯豆间作)下氮素水平对威芋3号产量、品质的影响.结果表明:薯豆间作显著提高威芋3号产量,比单作和薯玉间作分别增产18.9%和7.8%,并显著提高薯块粗蛋白含量,但使淀粉含量降低.在3种施氮水平中(N0,N12.8,N16),薯块粗蛋白含量随施氮量的增加而提高.氮素水平与间作模式对威芋3号产量、粗蛋白、还原糖和Vc含量均有显著的交互效应.

| Abstract: | Effects of cropping pattern and nitrogen level on yield and quality of the potato cultivar Weiyu 3 were studied by field experiment to know the nutritional effect of nitrogen on Weiyu 3 under intercropping condition.The results showed that yield of Weiyu 3 intercropped with kidney bean was significantly increased and was 18.9 % and 7.8 % higher than that of monoculture and intercropping with corn respectively.The crude protein content of potato was significantly increased while the starch content decreased.... |
