The Effect Of Earthworm Manure And Straw Biochar To Control Greenhouse Continuous Cropping Cucumber

In recent years,Chinese gardening develops very rapidly,cultivated area increased year by year,the formation of different regional types of facilities,production mode and technology system,but the vegetable production for continuous crop,some of the old areas of continuous cropping obstacle is becoming increasingly serious,restricting the sustainable development of vegetables.In this experiment,the grim situation occurred in continuous cropping obstacle of horticultural crops,the successive planting of cucumber,take "Jinchun 5"cucumber as test materia,set different fertilization,focusing on earthworm manure and straw biochar through two kinds of agricultural organic solid waste treatment on the effect of continuous cropping cucumber,alleviating continuous cropping obstacles through the reasonable fertilization mode in order to achieve high quality,to lay a theoretical foundation for the study of continuous cropping obstacle.The texperiment is divided into two parts:the effect of earthworm manure and straw biochar have the effect of continuous cropping of cucumber,different treatments in different years of continuous cropping cucumber were measured of plant taits,yield traits,fruit quality traits and soil physicochemical properties.The following results were obtained.1.Earthworm manure,straw biochar,common biological organic fertilizer in continuous cropping cucumber vegetative growth is good,and compared between the two difference is small;while other fertilizer treatments were decreased,the inorganic compound fertilizer(CK)decreased the most.2.1n 2016 the yield of continuous cropping cucumber than the 2015 average annual decline in different degrees.Earthworm manure,straw biochar can significantly improve the cucumber yield,VP3,VP2 with higher yield,significantly higher than CK;straw biochar production is relatively high,significantly higher than CK.3.1n 2016 the quality of continuous cropping cucumber than the 2015 average annual decline in different degrees.The earthworm manure can significantly improve cucumber solids content,soluble sugar,soluble protein and vitamin C;straw biochar to improve the quality of the continuous cropping cucumber is not obvious.4.Earthworm manure can significantly improve cucumber soil organic matter,microbial nitrogen content,total phosphorus,slow pH drop and EC rise;straw biochar can significantly improve the ammonia nitrogen,cucumber continuous cropping soil microbial nitrogen content,total phosphorus,slow pH drop and EC rise.
