日光温室蔬菜栽培废弃基质露地还田对土壤理化性质及辣椒生理特性和产量的影响
Effects of Returning Different Amount of Waste Substrate to Field on the Physicochemical Properties of Soil and the Physiological Characteristics and Yield of Pepper
摘要
Abstract
Planted pepper after returning waste substrate which cultivated vegetables in greenhouse continuously for 6 years to open field to explore the effect of soil and pepper growth from returning substrate to field.Set four returning amount:0,45,90,135 m3/ha,and measured physicochemical properties of soil and the physiological characteristics and yield of pepper.The results showed that returning waste substrate to field could reduce the degree of soil acidification and bulk density of soil,slightly increasing soil porosity,maintain soil void ratio,improved the physical and chemical properties of soil.Promoted the growth of pepper plants and the accumulation of dry matter,meanwhile T2 was the best on plant height,stem diameter and matter accumulation.Enhanced the performance of photosynthetic fluorescence of pepper leaves,T2 had the highest value of Pn,Tr,Gs,Fv/Fm and ΦPSⅡ,and T1 of qP,T3 was the minimum on NPQ.Raised the fruit quality and yield of pepper,maximum yield was found in T2 treatment,67.04 t/ha;The highest content of soluble sugar was T2,2.21%,the highest content of Vc was T3,1.97 mg/g,T1 had the highest content of soluble protein and lowest of nitrate,2.07,204.93 mg/kg.But at the same time,large returning amount(135 m3/ha) brought some continuous cropping poison in the early stage of pepper growth,this phenomenon disappeared in the late growth period,at last,the indexes were still all better than no returning treatment.Returning waste substrate to field was a practical and effective reusing way,and 90 m3/ha could be recommended as the amount of returning (in the case of the same crop planting).关键词
