The Study Of Effect On Siraitia Grosvenorii And Desmodium Styracifolium Intercropping

Siraitia grosvenorii industry is one of the mainstay in Guilin,Guangxi Province.tranditional Siraitia grosvenorii cultivation pattern is a serious waste of land resources.Considering to improve land use through the cropping of intercropping and interplanting and so on,and to raise economic benefit.This experiment studied Siraitia grosvenorii intercropping Chinese herbal medicine Desmodium styracifolium,to explore the feasibility of Siraitia grosvenorii intercropping Desmodium styracifolium through analyzing several aspects of farmland small-scale environment,soil environment,physiological index and agronomic traits of Desmodium styracifolium,yield and quality of Siraitia grosvenorii and Desmodium styracifolium of intercropping patterns and two single crops planting,and to find a new Siraitia grosvenorii cultivation pattern.The experiment results are as follows:1、 Before Siraitia grosvenorii overgrowning with awning, the growth of Siraitia grosvenorii and Desmodium styracifolium was not affected by Intercropping.After September,Siraitia grosvenorii overgrowning with awning and overshadowing Desmodium styracifolium, Desmodium styracifolium quality decreased.2、Intercropping caused the content of chlorophyll and chlorophyll b increase,and does not much affect the net photosynthetic rate,soluble protein, SOD activity, POD activity and nutriment of N,P and K.3、Intercropping caused soil actinomyces number falling,anddoes not much affect soil bacteria and soil fungi number;improved the soil catalase activity, reduced the soil urease activity,and had little impact of soil nutrients.4、Fruit numbers, large and mediumsized fruit rates,Substandard fruit rates of Siraitia grosvenorii was lesser and small fruit rates of Siraitia grosvenorii was higher than single planting in Intercropping.Mogroside V and Vitamin C content was lesser than single planting, moisture content and total suger content was more than single planting in Intercropping mode.5、Main stem wsa longer,basal stem was bolder and brunch was lesser in Intercropping mode,and intercropping improved Desmodium styracifolium yield to some extent,but reduced total flavonoids content.6、Siraitia grosvenorii intercropping Desmodium styracifolium can improve the economic benefit of acreage of land.
