基质用量对黄瓜生长发育的影响

为研究基质无土栽培中基质的最佳用量,试验研究了每株1￣5L的基质用量对黄瓜生长发育的影响。结果表明,黄瓜生长发育和产量受根际基质用量的影响,在1￣5L的范围内,基质用量增多,黄瓜的生长越好,产量也越高。但每株基质用量在4￣5L时,黄瓜生长及产量差异不显著;但在除去基质成本时,基质用量4L的黄瓜效益比5L的高370元/667m2。因此,为了降低生产成本,提高经济效益,黄瓜采用炭化稻壳和木屑混合基质栽培时,每株基质用量可采用4L,即每667m2的用量为8m3。

The Effect of Substrates Quantity on the Growth and Development of Cucumber

In order to study the best substrate quantity in the eco-organic soilless culture system, substrate quantity ranged 1~5L per plant on cucumber growth and development were studied. The results showed that cucumber growth and output were affected by the substrates quantity, within the substrates range of 1~5L per plant, the more substrate quantity used, the better of cucumber growth and also the higher output. However, there were no significant differences of growth and output of cucumber between 4L and 5L per plant. Considered the substrates cost, the benefit of 4L per plant were higher than 5L per plant with 370 yuan per 667m2. In order to reduce cost and improve benefits, when rice hull ash and sawdust were used as substrates, 4L per plant, i.e. 8m3 per 667m2, should be used.
