不同尺寸袋培对黄瓜生长发育和产量的影响

Effect of Different Sizes of Growth Bags with Medium on the Growth and Yield of Cucumber

以聚丙烯编织袋(蛇皮袋)为材料做成6种不同尺寸基质栽培袋,分别为(边长×边长,单位:cm):20×25(T1)、25×30(T2)、30×30(T3)、30×35(T4)、35×35(T5)、35×40(T6),分别装入2.5、4、5、6.5、8.5、10 L体积比为2∶1的草炭和蛭石的混合基质中;以T5为对照,在日光温室内栽培"津春4号"黄瓜,研究了不同尺寸的栽培袋对黄瓜生长发育、产量和品质的影响。结果表明:装入5 L基质的T3处理接近于对照水平,少于5 L的栽培袋产量急剧下降,高于5 L的处理增产幅度变得较小,且差异不显著,在生产中装入5 L基质的栽培袋比较适合单株黄瓜的栽培。

The effect of different sizes of growth bags with medium to the growth and yield of cucumber in greenhouse were studied.Use knitting bag of polypropylene to make growth bags,including 6 treatments（side longth×side longth,unit：cm）：20×25（T1）,25×30（T2）,30×30（T3）,30×35（T4）,35×35（T5,CK）,35×40（T6）.The mixture medium of 2∶1 vermiculite was put into the bags,2.5,4,5,6.5,8.5,10 L respectively.The results showed that the growth and yield of cucumber of T3 was close to the CK and the yield of cucumber that planted in the bags that less than 5 L reduced sharply.The yield inecreasing of the treatment above 5 L was ingnificant.The treatment of putting 5 L（sixe：30×30） was suitable to single cucumber planting
