贵州地形及气候条件下生物降解地膜对白菜产量、土壤环境和经济效益的影响
Effects of biodegradable mulching films on yield,soil environment and economic benefit of Chinese cabbage under terrain and climate conditions in Guizhou province
摘要
Abstract
To explore the application effect on the biodegradable mulch films in vegetable cultivation,the breeding in greenhouse and cultivation in field were carried out by using Chinese cabbage was used as an experimental material.Tak-ing an ordinary PE mulch film as a control,5 different types of biodegradable mulch films with different thickness and dif-ferent landfill materials were measured,and a total of 5 treatments were conducted to investigate the effect of biodegrad-able mulch films on the yield,soil environment,and economic benefits of the cabbage.The results indicated that the soil moisture content,PH value,cation exchange capacity,soil organic matter,soil total phosphorus,available phosphorus and available potassium contents of the degradable film treatment were higher than those of the ordinary one;however,their total salt content and bulk density were lower than those of the ordinary one.In terms of soil effects,the contents of most soil physical and chemical properties under the biodegradable plastic film treatment were higher than those under the ordinary PE plastic film treatment.In terms of the effect on the yield of Chinese cabbage,the biodegradable and ordinary PE films with the same thickness exhibited the same effect on the yield of Chinese cabbage.In terms of the benefits,the ratio of the profit and yield to investment of the cabbage growing under biodegradable mulch films were higher than that of the ordinary one.The promotion of thin-thickness biodegradable films in cabbage planting in Guizhou not only can keep the yield of the cabbage,but also can improve ecological benefits and increase economic benefits.This helps to real-ize the scientific concept that clean waters and green mountains are invaluable assets.关键词
