Effects of Combination of Plug and Additive on Nutrient and Microbial Community of Watermelon Plant and Rhizosphere Soil
摘要
Abstract
To investigate the effects of different sizes of plug seedling,water-retaining agent and microbial combination on mineral nutrient ac-cumulation and soil properties of watermelon plants,and to provide theoretical basis for cultivating strong and good quality watermelon seed-lings.Three factors and three levels were used to design the orthogonal test,the hole tray sizes were 21,32,66,the types of water-retaining agents were blank,granule,powder water-retaining agent,the additives were Bacillus amylolique faciens and chitooligosaccharide and lentin-an,fish protein and aminooligosac charide,blank.The effects of different substrates added with water-retaining agent and microbial combina-tion on watermelon plant and growth environment were studied by analyzing plant nutrients,rhizosphere soil nutrients and microbial community during fruit ripening.The results were as follows:the contents of S,Mg and Fe in plant and rhizosphere soil were significantly increased by 21-hole plug seedling;the contents of P,K,Ca and Fe in plant and rhizosphere soil were increased significantly by using granular water retaining agent;the combination of Bacillus amylolique faciens and chitooligosaccharide and lentinan significantly increased the population and species richness of rhizosphere soil,and improved the rhizosphere soil environment.关键词
