不同类型地膜覆盖对滴灌马铃薯产量和经济效益的影响
Effects of Different Types of Plastic Film Mulching on the Yield and Economic Benefit of Drip-irrigated Potatoes
摘要
Abstract
This study investigated the effects of plastic film mulching with different colors and thicknesses on potato growth and economic benefit,aiming to provide a theoretical basis for efficient drip-irrigated potato production in Yongchang County.With no mulching as the control,treatments of black and white polyethylene(PE)films with thicknesses of 0.010,0.012,0.015,0.018,and 0.020 mm were applied.Indicators such as potato growth period,yield components,commercial rate,yield,and economic benefit were measured to determine the optimal film color and thickness.Results showed that film mulching promoted potato growth and development,advanced tuber initiation,and extended tuber growth duration.Under black film mulching,the number of tubers per plant,number and weight of medium-large tubers,and commercial rate were higher with 0.010 and 0.012 mm treatments.Under white film mulching,the number of tubers per plant,fresh tuber weight per plant,number and weight of medium-large tubers,and commercial rate were higher with 0.012 and 0.015 mm treatments.Compared with the control,the above indications in the 0.012 mm treatment increased by 46.9%,115.0%,84.6%,24.9%and 76.0%,respectively,while those in the 0.015 mm treatment increased by 51.0%,112.2%,100.0%,36.1%and 79.7%,respectively.Potato yield and economic benefit under white film mulching were overall higher than under black film mulching,with the 0.015 mm white film showing the best yield-enhancing effect.The two-year average potato yield reached 37 390.6 kg/ha,59.3%higher than the control,while net income reached 49 043.4 Yuan/ha,31 792.2 Yuan/ha higher than the control,with an increase of 184.3%.In conclusion,the 0.015 mm white film mulching achieved the highest yield and economic benefit and can be recommended as the main planting model for drip-irrigated potato production with film mulching in Yongchang County.关键词
