摘要: 为探究不同茄属杂草秸秆对果树生长及养分吸收的影响,通过盆栽试验,研究了4种茄属杂草龙葵(Solanum nigrum)、黄果龙葵(Solanum diphyllum)、红果龙葵(Solanum alatum)和矮株龙葵(Solanum nigrum var. humile)秸秆对树番茄(Cyphomandra betacea)幼苗生长及养分吸收的影响。结果表明,矮株龙葵秸秆和龙葵秸秆处理在一定程度上增加了树番茄幼苗的生物量及光合色素(叶绿素a、叶绿素b、叶绿素总量和类胡萝卜素)含量,其余2种秸秆处理的影响不显著。黄果龙葵秸秆和龙葵秸秆处理提高了树番茄幼苗的超氧化物歧化酶活性,其余2种秸秆处理的影响则起降低的作用。4种茄属杂草秸秆处理对树番茄幼苗的过氧化物酶活性、过氧化氢酶活性和可溶性蛋白含量的影响不显著或起降低的作用。黄果龙葵秸杆处理提高了树番茄幼苗的全氮、全磷和全钾含量,其余3种秸秆处理的影响不显著或在一定程度上起降低的作用。

Abstract: To explore the effects of different Solanum spp. weeds straws on the growth and nutrient absorption of fruit trees, the effects of four Solanum spp. weeds (Solanum nigrum, Solanum diphyllum, Solanum alatum and Solanum nigrum var. humile) straws on the growth and nutrient absorption of Cyphomandra betacea seedlings were studied through a pot experiment. The results showed that the straws of Solanum nigrum var. humile and Solanum nigrum treatments increased the biomass and photosynthetic pigments (chlorophyll a, chlorophyll b, total chlorophyll and carotenoids) contents of Cyphomandra betacea seedlings to a certain extent, and the other two straws treatments had no significant effects. The straws of Solanum diphyllum and Solanum nigrum treatments enhanced the superoxide dismutase activity of Cyphomandra betacea seedlings, and the other two straws treatments had reducing effects. The straws of four Solanum spp. weeds treatments had no significant effects or reducing effects on the peroxidase activity, catalase activity and soluble protein content of Cyphomandra betacea seedlings. The straw of Solanum diphyllum treatment increased the total nitrogen, total phosphorus and total potassium contents in Cyphomandra betacea seedlings, and the other three straws treatments had no significant effect or reducing effects to a certain extent.

Key words: Cyphomandra betacea, Solanum spp. weed straw, growth, nutrient absorption
