不同地膜覆盖栽培对花生经济性状及产量的影响与效益分析

花生配色地膜覆盖栽培与普通地膜出苗期相同,黑色地膜出苗晚1d,对花生出苗率无不良影响,单株结果数分别增加1.7个和1.5个,饱果数增加2.4个和1.3个,秕果数减少0.4个和0.7个。667m2平均产量分别为394.5kg和392.5kg,比普通地膜分别增产24.5kg和22.5kg,增产率6.62%和6.08%。与普通地膜单位产量差异均达极显著水平。按照花生5元/kg计算,配色地膜和黑色地膜667m2可增加经济效益102.5元和92.5元,分子地膜效果较差。生产上可大面积推广配色地膜和黑色地膜覆盖栽培。

Effects of Different Film Mulching on the Economic Character and Yield of Peanut and Benefit Analysis

Both black-white mulch film and black mulch film had no adverse effect on the rate of emergence compared with ordinary mulch film.The time of emergence of black-white mulched peanut was the same as that of ordinary film.However,the emergence time of black mulched peanut was one day postponed.The No.of pods per plant was increased by 1.7 and 1.5,the No.of full pods per plant was increased by 2.4 and 1.3,the No.of hollow kernel pods per plant was reduced 0.4 and 0.7,respectively.The yield increased 5 917.5kg/ha and 5 887.5kg/ha with increase rate of 6.62% and 6.08% respectively,reaching the 0.01 significant level.According to a price of 5 yuan/kg,economic benefit can be enhanced by 1 573.5 yuan/ha and 1 387.5 yuan/ha.Molecular film had no significant effect.Thereby black-white film and black film can be applied and popularized in peanuts production.
