木薯//大豆间距对间作作物农艺性状及品质的影响

木薯间作短期作物是常见的栽培模式之一,本文以木薯南植199和大豆华春8号为试验材料,在不同间距处理下,记录和测定作物的农艺性状和品质,试图了解间作距离对其的影响,为两种作物合理配置获得高产高效提供理论和技术依据。结果显示:间距处理对大豆的有效分枝数、主茎节数和木薯的株高具有显著影响,而对两种作物的其它农艺性状无显著影响。当间作间距为D30时,大豆蛋白质、粗脂肪和3种脂肪酸含量显著提高,木薯淀粉含量高于其它处理,但低于单作木薯。此外,间距处理对木薯的单株产量有影响显著,单作和D50间距处理的木薯单株产量高于其它处理,但对大豆的单株产量无显著影响。结果表明D30的间距间作模式下,木薯和大豆的品质性状具有优势,而D50的间距间作模式下,木薯和大豆的产量性状具有优势。

Effects of the Cassava and Soybean Spacing in an Intercropping System on the Agronomic Traits and Crop Quality

The cassava intercropping short-term crop is one of the common cultivation patterns.In this paper,cassava Plantation 199 and soybean Huachun 8 were used as experimental materials.The agronomic traits and quality of the two crops were measured under different spacing treatments.This research was mean to reveal the impact of intercropping distance on the agronomic traits and quality,and to provide theoretical and technical basis of the rational allocation and high yield of the two crops.The results showed that the number of the effective branching,the main stem nodes of soybean and the plant height of cassava were significantly affected by the intercropping,while there was no significant effect on other agronomic traits of the two crops.With intercropping spacing D30 treatment,soybean protein content,fat content and three kind of fatty acid contents were significantly increased,cassava starch content of cassava was lower than mono-cropping treatment,although higher than other spacing treatments.Moreover,intercropping had the more significant effect on the cassava,the cassava yield was higher than other treatments,while there was no significant effect on the yield of soybean.In conclusion,the quality traits of cassava and soybean had an advantage under the D30 intercropping distance,while the yield traits of corp had advantages under the D50 intercropping distrance.
