生物可降解地膜对土壤肥力及马铃薯产量的影响
Influence of Biodegradable Membrane on Soil Fertility and Potato Yield
摘要
Abstract
Experimental was conducted with material of'Zihuabai',five kinds of mulching material cultivation mode were set,including bare land,polyethylene plastic film,biodegradable membrane A,corn stalk and biodegradable membrane B,which was conducted in the seedling stage,tuber initiation stage,tuber expansion period,starch accumulation period and maturation period.In order to explore the effects of different biodegradable films on soil fertility and the potato production,soil simple of 0 ～ 20 cm soil layer were collected at different potato stages to determine the soil fertility,potato tubers were collected at maturation period to measure the potato production.The results indicated that the soil fertility and available nutrient were increased under the treatments of biodegradable A membrane,corn stalk and biodegradable B membrane.The effect of biodegradable membrane B was the best,the available P,available K in soil were increased significandy,the soil organic matter,alkaline hydrolysis nitrogen available P,available K were increased 2.51 g/kg,7.24 mg/kg,16.05 mg/kg and 9.68 mg/kg.Compared with bare land,the tuber yield of polyethylene plastic film,biodegradable A membrane,corn stalk and biodegradable B membrane were increased 6.25 ％,21.18％,17.07％,31.71％.Therefore,the biodegradable membrane mulching could improve soil fertility and the yield of potato production,under different coverage conditions,biodegradable membrane B showed the best effect.关键词
