In order to study the changes of cassava yield, quality, photosynthetic performance and soil enzyme activities under cassava intercropping mode of muskmelon, and to provide theoretical basis for improving the cultivation technology of cassava intercropping muskmelon in Changsha, cassava (Nanzhi 199) and muskmelon (Xiangtian thin crisp) were used as the experimental materials, cassava monoculture (CK) was used as the control, and three planting densities (T1, T2, T3, plant spacing of 0.5, 0.7, 0.9 m) of muskmelon in cassava intercropping were used as treatments. Compared with monoculture cassava, the number of tuber per plant, dry matter percentage and starch content of cassava were not significantly changed under intercropping treatment, but the yield per plant, economic yield, soluble protein and vitamin C content of cassava increased under intercropping treatment. The effects of each treatment on cassava yield and quality were in the order of T2>T3>T1>CK. The photosynthetic capacity of cassava leaves in intercropping mode significantly increased, and the net photosynthetic rate (Pn) of cassava leaves in root tuber formation and expansion stage was significantly higher than that of monoculture treatment. The Pn of cassava leaves under T2 treatment was significantly higher than that under other treatments, and the intercropping treatment had significantly higher intercellular CO2 concentration (Ci), stomatal conductance (Gs) and transpiration rate (Tr) than those under monoculture treatment. With the growth of cassava plants, the activity of sucrase in soil showed a trend of decreasing first and then increasing, urease showed a trend of increasing first and then decreasing, while acid phosphatase and catalase showed a trend of decreasing gradually. The activity of sucrase, acid phosphatase and catalase in soil was significantly promoted by intercropping at different stages, but had little effect on urease activity. The activity of sucrase, acid phosphatase and catalase in soil of T2 treatment was significantly higher than those of monoculture treatment at the expansion and maturity stages of cassava roots. In conclusion: Compared with cassava monoculture, cassava intercropping model improved cassava photosynthetic performance and soil fertility level, so as to improve the economic yield and quality of cassava. The optimal cultivation model with two rows of cassava intercropping and one row of melon with a distance of 0.7 m was suitable for the cassava intercropping model in Changsha.

为了研究木薯间作甜瓜模式下木薯产量、品质、光合性能及土壤酶活性的变化,为进一步改进长沙产区木薯间作甜瓜栽培技术提供理论依据。本研究以木薯(南植 199)和甜瓜(湘甜薄脆)为试验材料,设计以木薯单作(CK)为对照,木薯间作甜瓜时,以甜瓜3种种植密度(T1、T2、T3,株距分别为0.5、0.7、0.9 m)为处理,研究木薯间作甜瓜对木薯产量、品质、光合性能及土壤酶活性的影响。结果表明:与木薯单作相比,木薯间作甜瓜处理下,木薯单株结薯数、干物率和淀粉含量无显著性变化,间作提高了木薯单株产量、经济产量、可溶性蛋白和维生素C含量,各处理对木薯产量与品质的影响大小依次为T2>T3>T1>CK。在间作模式下,木薯叶片的光合能力得到显著提升,在块根形成期与膨大期木薯叶片的净光合速率(Pn)显著高于单作处理;在块根成熟期T2处理下,木薯叶片的Pn显著高于其他处理,间作处理下木薯叶片的胞间CO2浓度(Ci)、气孔导度(Gs)和蒸腾速率(Tr)均显著高于单作处理。随着木薯植株的生长,土壤中蔗糖酶活性表现出先降后增的趋势,脲酶表现出先增后降的趋势,而酸性磷酸酶和过氧化氢酶表现出逐渐下降的趋势。不同时期间作对土壤中蔗糖酶、酸性磷酸酶和过氧化氢酶的活力有明显的促进作用,但对脲酶活性的影响较小,其中T2处理在木薯块根膨大期与块根成熟期土壤中蔗糖酶、酸性磷酸酶和过氧化氢酶的活力显著高于单作处理。综上表明,与木薯单作相比,木薯间作甜瓜模式提高了木薯光合性能及土壤肥力水平,从而提高了木薯的经济产量和品质,其中以2行木薯间作1行甜瓜,甜瓜株距为0.7 m的栽培模式最优,为适合长沙产区的木薯间作甜瓜模式。

为了研究木薯间作甜瓜模式下木薯产量、品质、光合性能及土壤酶活性的变化,为进一步改进长沙产区木薯间作甜瓜栽培技术提供理论依据。本研究以木薯(南植 199)和甜瓜(湘甜薄脆)为试验材料,设计以木薯单作(CK)为对照,木薯间作甜瓜时,以甜瓜3种种植密度(T1、T2、T3,株距分别为0.5、0.7、0.9 m)为处理,研究木薯间作甜瓜对木薯产量、品质、光合性能及土壤酶活性的影响。结果表明:与木薯单作相比,木薯间作甜瓜处理下,木薯单株结薯数、干物率和淀粉含量无显著性变化,间作提高了木薯单株产量、经济产量、可溶性蛋白和维生素C含量,各处理对木薯产量与品质的影响大小依次为T2>T3>T1>CK。在间作模式下,木薯叶片的光合能力得到显著提升,在块根形成期与膨大期木薯叶片的净光合速率(Pn)显著高于单作处理;在块根成熟期T2处理下,木薯叶片的Pn显著高于其他处理,间作处理下木薯叶片的胞间CO2浓度(Ci)、气孔导度(Gs)和蒸腾速率(Tr)均显著高于单作处理。随着木薯植株的生长,土壤中蔗糖酶活性表现出先降后增的趋势,脲酶表现出先增后降的趋势,而酸性磷酸酶和过氧化氢酶表现出逐渐下降的趋势。不同时期间作对土壤中蔗糖酶、酸性磷酸酶和过氧化氢酶的活力有明显的促进作用,但对脲酶活性的影响较小,其中T2处理在木薯块根膨大期与块根成熟期土壤中蔗糖酶、酸性磷酸酶和过氧化氢酶的活力显著高于单作处理。综上表明,与木薯单作相比,木薯间作甜瓜模式提高了木薯光合性能及土壤肥力水平,从而提高了木薯的经济产量和品质,其中以2行木薯间作1行甜瓜,甜瓜株距为0.7 m的栽培模式最优,为适合长沙产区的木薯间作甜瓜模式。

In order to study the changes of cassava yield, quality, photosynthetic performance and soil enzyme activities under cassava intercropping mode of muskmelon, and to provide theoretical basis for improving the cultivation technology of cassava intercropping muskmelon in Changsha, cassava (Nanzhi 199) and muskmelon (Xiangtian thin crisp) were used as the experimental materials, cassava monoculture (CK) was used as the control, and three planting densities (T1, T2, T3, plant spacing of 0.5, 0.7, 0.9 m) of muskmelon in cassava intercropping were used as treatments. Compared with monoculture cassava, the number of tuber per plant, dry matter percentage and starch content of cassava were not significantly changed under intercropping treatment, but the yield per plant, economic yield, soluble protein and vitamin C content of cassava increased under intercropping treatment. The effects of each treatment on cassava yield and quality were in the order of T2>T3>T1>CK. The photosynthetic capacity of cassava leaves in intercropping mode significantly increased, and the net photosynthetic rate (Pn) of cassava leaves in root tuber formation and expansion stage was significantly higher than that of monoculture treatment. The Pn of cassava leaves under T2 treatment was significantly higher than that under other treatments, and the intercropping treatment had significantly higher intercellular CO2 concentration (Ci), stomatal conductance (Gs) and transpiration rate (Tr) than those under monoculture treatment. With the growth of cassava plants, the activity of sucrase in soil showed a trend of decreasing first and then increasing, urease showed a trend of increasing first and then decreasing, while acid phosphatase and catalase showed a trend of decreasing gradually. The activity of sucrase, acid phosphatase and catalase in soil was significantly promoted by intercropping at different stages, but had little effect on urease activity. The activity of sucrase, acid phosphatase and catalase in soil of T2 treatment was significantly higher than those of monoculture treatment at the expansion and maturity stages of cassava roots. In conclusion: Compared with cassava monoculture, cassava intercropping model improved cassava photosynthetic performance and soil fertility level, so as to improve the economic yield and quality of cassava. The optimal cultivation model with two rows of cassava intercropping and one row of melon with a distance of 0.7 m was suitable for the cassava intercropping model in Changsha.
