海绵营养液块对黄瓜育苗效果的影响

Influnence of Nursery Effect of Sponge in Substrate-free Nutrient Solution for Cucumber

以5cm×5cm×5cm的海绵块为试材,以黄瓜为研究对象,以蛭石∶椰糠∶泥炭=1∶1∶1的混合基质并浇灌营养液为对照,研究了1.5、2.5、3.5cm营养液层深度的海绵块,对黄瓜幼苗综合生长指标的影响,以期筛选适合海绵块育苗的营养液深度。结果表明:与CK相比,3种营养液深度海绵块育苗处理黄瓜幼苗的干鲜重、茎粗、株高、壮苗指数、真叶面积、子叶大小均显著优于CK,综合分析T1处理(液深1.5cm)效果最好。

Taking 5 cm× 5 cm×5 cm sponge as test material, cucumber as test object, with vermiculite：coir dust：peat-- 1 ： 1 ： 1 as control, the effect of sponge with 1.5 cm, 2.5 cm and 3.5 cm depth nutrient solution on the growth index of cucumber seedling was studied to select the suitable depth nutrient solution. The results showed that three treatments had significant advantage over control on fresh and dry weight ,stem width and length, seedling index,the cotyledon area and the main leaves area,and T1 （1.5 depth nutrient solution） was the most suitable way for cucumber seedlings.
