不同农业有机废料发酵基质栽培番茄试验

Study on the Cultivation of Tomatoes with Different Organic Wasted as Eco-organic Soilless Cultivation Substrate

为更有效地克服土壤连作障碍,以宁夏地区主要的农业废弃物玉米秸秆、牛粪、鸡粪、沼渣、菇渣为主要原料进行番茄无土栽培基质发酵筛选试验。结果表明:不同有机发酵基质pH、EC表现为收获后较栽培前有上升的趋势;速效氮、速效磷、速效钾均表现为收获后较栽培前有显著下降的趋势。黄牛粪:玉米秸:鸡粪=2:2:1、黄牛粪:苜蓿=2:1、玉米秸:鸡粪=2:1、菇渣:黄牛粪:鸡粪=1:2:1进行无土栽培番茄生长较为健壮,综合品质较优,产量也显著高于其它处理。

In order to overcome soil obstacles effectively,through fermentation of organic wasted resources to replace nonrenewable matter resource corn stalks,mushroom wasted,chicken manure,clover,cow manure,rice bran were used as the main fermentative resources of eco-organic soilless cultivation substrate.The results indicated that pH and EC all went up after harvest,otherwise available N,available P,available K went down with different fermentation organic cultivation substrate.Among eight of cultivation substrate formula,the tomatoes cultivated with proportion of cow manure∶corn stalks∶chicken manure=2∶2∶1,cow manure∶clover= 2∶1,corn stalks∶chicken manure=2∶1,mushroom wasted∶cow manure∶chicken manure=1∶2∶1 grew more strongly and had better quality,yield of per 667 m2 were also much higher than the other treatments.
