施肥量对基质培黄瓜生长发育的影响

为降低基质培生产成本,方便生产者取得简单易用的肥料,试验研究了猪粪、磷酸二氢铵和复合肥三种肥料不同使用量对黄瓜生长发育的影响。结果表明,每株黄瓜施干猪粪166.7g 磷酸二氢铵16.7g 复合肥16.7g和猪粪100g 磷酸二氢铵10g 复合肥10g施肥较多的2个处理的黄瓜长势、叶绿素含量、胡萝卜素及净光合速率均较好,果实品质除硝酸盐比其它处理稍高以外,其可溶性蛋白、可溶性总糖、Vc含量均比其它处理有所提高。特别是每株黄瓜施猪粪100g 磷酸二氢铵10g 复合肥10g的处理产量不仅高于营养液滴灌,而且显著高于其它处理。因此,黄瓜有机基质培中,适量施用化肥可以促进黄瓜生长、达到优质高产的目的。

The Effect of Fertilizer Quantity on the Growth and Development of Cucumber in the Eco-organic Soilless Culture System

In order to lower the production cost, and make the fertilizer been convenient for the manufacturer to obtain in brief and easily, experiment was done to study the effect of different quantity of dry swine waste, NH4H2PO4 and composite fertilizer on the growth and development of cucumber in soilless culture. The results showed that the two more fertilizer treatments of dry swine waste 166.7g NH4H2PO4 16.7g composite fertilizer 16.7g per plant and dry swine waste 100g NH4H2PO4 10g composite fertilizer 10g per plant had the higher plant growth, chlorophyll content, carotenoidse content and photosynthesis rate. Except the nitrate content is higher than other treatments, the fruit quality such as soluble protein, total soluble sugar and Vc content is better than other treatments. The output of treatment dry swine waste 100g NH4H2PO4 10g composite fertilizer 10g per plant was not only higher than nutrient solution treatment, but also significant higher than other treatments. As a result, in eco-organic soilless culture system, the proper use of chemical fertilizer can improve plant growth and output of cucumber.
