摘要
在种植蔬菜多年的夹沙土上,以进口化学复合肥作为对照的田间试验结果表明,腐植酸复混肥不仅增产增益明显,而且具有改土扩容降低土壤盐分的作用。产量效应,番茄增产6.5%~30.5%,平均增产16.4%;黄瓜增产10.9%。经济效益,番茄平均每公顷比对照增加净收入2.349万元;黄瓜每公顷比对照增加净收入1.98万元。
Using chemical fertilizer as the control, a field experiment was conducted to study the effects of humic acid compound fertilizer on vegetables growth. The results showed that applying humic acid compound fertilizer could shorten the growth time after transplanting seedling, promote the growth speed, bearing fruit, and expanding fruit. Yields of tomato and cucumber were increased by 16.4% and 10.9%, respectively. And the net income of tomato and cucumber were enhanced by 24800 and 23800 yuan per hectare, respectively.
