不同甘薯品种套作玉米下的群体产量及效益分析
Analysis of Population Yield and Benefit of Different Sweet Potato Varieties Intercropped by Maize
摘要
Abstract
Seven different varieties of sweet potato were used to study their population yield advantage and economic benefit when they intercropped with maize through using randomized block design .The results showed that the yield of sweet potato under this intercropping mode was lower than that under monocropping mode .Under sweet potato-maize intercropping mode , there was a significant difference in the number of tubers per plant , tuber weight per plant , and tuber yield among different varieties of sweet po-tato.The tuber yield and starch yield of sweet potato were higher when maize intercropped with Nanshu 88, Xushu 22 and Yushu 2. When 7 sweet potato varieties intercropped with maize , the land equivalent ratios of complex populations were all more than 1, re-vealing that the intercropping advantage existed .The monocropping or intercropping of special sweet potato varieties ( Ning 4-6, Ji-heishu 1, E08101 and so on) with maize obtained a higher output value .关键词
