秸秆对日光温室连作有机基质的修复效果
Remediation Effect of Crop Straw on Continuous Cultivated Organic Substrate in Solar Greenhouse
摘要
Abstract
The soil fertility of organic substrate is severely declined by continuous cultivation in facilities.In order to maintain the sustainable cultivation and utilization of organic substrate, rotten straw is added to continuous cultivated organic substrate in solar greenhouse.This paper studied the remediation effect of adding straw on continuous cultivated organic substrate.The results show that the bulk density of organic substrate added with composed straw decreased by 25.0%-30.4%,compared to continuous cultivated organic substrate,the total porosity is increased,and the substrate organic matter contents are increased,which will increase along with the increase of straw application quantity.The available N,P,K contents in substrate are all increased by adding straw.The total N,P contents and available N,P of organic substrate∶maize stalk=1V∶2V is the highest.By adding straw the substrate temperature in the morning of spring is 0.80-1.50 ℃ higher than that of continuous cultivated organic substrate.Whereas the oxygen concentration is declined remarkably,and organic substrate∶wheat straw = 1V∶2V is the lowest.By adding straw to continuous cultivated organic substrate,the plant growth,chlorophyll contents and root system vigor of cultivated cucumber are remarkably improved,its yield is increased and fruit quality is also improved.The cucumber yield in the treatment with organic substrate∶wheat straw=1V∶1V is the highest,which is increased by 20.87%than that of the continuous cultivated organic substrate.Therefore,adding straw to continuous cultivated organic substrate can significantly improve the physicochemical characteristics of organic substrate,and increase the yield of cucumber.The comprehensive result of treatment organic substrate∶wheat straw=1V∶1V is the best.关键词
