- 摘要:
- 随着保护地生产年限的增加, 哈尔滨市蔬菜保护地土壤养分发生极大变化, 研究其变化对哈尔滨市保护地番茄生产具有科学的指导意义。经研究, 哈尔滨市蔬菜保护地土壤养分含有较大幅度的提高;新保护地不同层次剖面土壤养分变化较老保护地显著, 老保护地土壤养分在不同剖面层次之间变化则趋于平缓, 说明土壤养分状况向着适于蔬菜生长发育方向发展。施用生物有机无机复混肥可促进番茄的生长发育, 使番茄的产量增加13.8%。
- Abstract:
- With the increasing of using periodof the protected land, the soil nutrient content of vegetable protected land in thecity of Harbin has changed obviously.It is very important to study the changes of the protected land nutrient to increase theproduction of tomato.The study showed that soil nutrient content had improved greatly.The changes of soil nutrient contentof different soil profile layers were significantly different in the recent protected lands, on the other hand, there were no sig-nificant differences among different soil profile layers of the former protected land.The situation of the soil nutrient had a-meliorated and vegetable couldgrow better.Biologic organic fertilizer andinorganic fertilizer couldpromote the growth of to-mato and increased the yield of tomato by 13.8%.
