日本小青瓜温室无土栽培基质筛选试验

Selection of Medium Formula of Soilless Cultivation for Japan's Small Cucumber in Greenhouse

为获得适宜日本小青瓜温室生产的经济、高效无土栽培基质,以椰糠、木糠、食用菌菇渣、粗河沙、消毒鸡粪为材料,配成6种不同比例的混合基质进行温室无土栽培试验。结果表明,用椰糠∶食用菌菇渣∶粗河沙按体积比2∶1∶1加上鸡粪4 kg/m3的无土基质栽培时,小青瓜营养生长最佳,叶片数最多,生殖生长发育最快,产量最高;其次为椰糠∶食用菌菇渣∶粗河沙为1∶2∶1加鸡粪4kg/m3的无土栽培基质。

In order to obtain economic, efficient and the best soilless medium formula for greenhouse production of Japan＇s small cucumber, we used coconut chaff, sawdust, mushroom residue, coarse river sand and sterilized chicken manure as substrate materials to mix 6 different ration media. The results showed that the best medium formula was V（ceconut chaff ）： V（mushroom residue）： V（coarse river sand） = 2： 1：1, added with sterilized chicken manure 4 kg/m3, For this medium formula, Japan＇s small cucumber showed the best vegetative growth, the largest number of leaves, the fastest reproductive geowth , the highest yield. The suboptimal medium formula was V（ coconut chaff ） ： V （ mushroom residue） ： V（ coarse river sand） = 1： 2：1, with sterilized chicken manure. 4 kg/m3 added .
