小麦秸秆堆肥茶灌根对设施蔬菜苗期生长的影响

Effects of Root Irrigation by Wheat Straw Compost and Tea on Facility Vegetables Seedling Growth

为了更好地利用秸秆堆肥产品,研究堆肥茶的最佳灌根使用量,促进秸秆堆肥化使用,以小麦秸秆添加尿素和腐熟剂混合发酵制作堆肥茶。以番茄和辣椒作为供试材料,全生长期定期采取5种不同灌根方式使用堆肥茶,研究不同处理对辣椒和番茄的生长发育形态及生理指标的影响。结果表明,不同处理堆肥茶的番茄和辣椒的生长及生物量有差别,其中番茄和辣椒的最佳处理均为每穴盘180mL堆肥茶。在该处理下,番茄和辣椒的植株生长形态和生物量的数值均高于其他几种处理,辣椒的株高、叶绿素含量分别比对照组高10.58%、9.5%;番茄的株高、叶绿素含量分别比对照组高9.52%、3.06%。综合比较认为,灌根小麦秸秆制作的堆肥茶每盘灌根180mL,能促进番茄和辣椒的植株形态的建成,提高植株叶片的叶绿素含量,增强光合作用,适宜番茄和辣椒生长。

In order to make better use of straw composting products,study on the best use of compost tea for root irrigation,to promote the utilization of Straw Composting. In this study,compost tea was made by mixing wheat straw with urea and decomposing agent. Tomato and hot pepper as the test materials,all kinds of long term regular 5 different root irrigation methods are used for compost tea,study on the effects of pepper on the growth and development of pepper and tomato The results of the study shows that,different treatments of compost tea had different effects on growth and biomass of tomato and pepper. Each dish of tomato and capsicum is best treated with 180mL composting tea for each tray. Under such treatment,the growth and biomass of tomato and pepper were higher than those of other treatments. Among them,compost tea 180mL for each Capsicum,in plant height and chlorophyll content,were higher than the control group 10.58%,9.5%;180mL per plate of tomato root compost tea,in plant height and chlorophyll content,were higher than the control group 9.52%,3.06%. In a comprehensive comparison,the compost tea made from wheat straw was irrigated with 180mL per dish can promote the plant morphogenesis of tomato and hot pepper, increase the content of chlorophyll in leaves,promote photosynthesis. It is a composting tea suitable for tomatoes and hot pepper.
