铺网和不同栽培基质对草皮质量的影响

摘要

通过田间试验,研究了铺网和不同栽培基质组合对草皮质量的影响,以期为网草皮生产提供依据。结果表明,铺网能显著提高草皮强度,降低草皮破损率,缩短成卷时间。农田土(60%)+羊粪(20%)+河沙(20%)成坪和成卷时间最短,草皮生长速度最快,质地最优,颜色最深,密度和强度最大；农田土(100%)草皮破损率最小；河沙(60%)+农田土(40%)草皮重量最轻。草皮综合质量评价显示,C基质即农田土(60%)+羊粪(20%)+河沙(20%)C+尼龙网是生产草皮的最佳组合。%The effects of net support and different cultivation medium on sod quality were studied.The re-sults showed that the net support could enhance the strength of sod,reduce the damage rate of sod and shorten the establishment time of sod.The cultivation medium with 60% cropland soil,20% sheep manure and 20% riv-er sand had the shortest establishment time,fastest growth rate,best texture,darkest color,highest density and strength.The medium of cropland soil had the lowest damage rate.The medium with 60% river sand and 40%cropland soil had the lightest weight.According to the comprehensive quality evaluation,the optimal cultivation medium of sod production was 60% farmland soil,20% sheep manure,20% river sand based on the nylon net.
