微米尺度煤系天然矿物对砂质土壤种植作物的促生效应研究

本研究以拟南芥、小番茄和菠菜为种植作物进行初步种植实验，通过设置不同含量煤系天然矿物以及不同肥力的土壤为实验变量，初步探讨了煤系天然矿物于砂质土壤中对植物促生效应的初步实验研究。接着进一步以菠菜作为种植作物开展连续种植实验，通过对比分析同一处理不同种植轮次、不同处理间菠菜产量、品质和土壤物理、化学、生物特性（pH值、生物酶活性、全氮、碱解氮、速效磷、阳离子交换量）的变化揭示SRM对作物和土壤的持续效应。

In this study, Arabidopsis thaliana, cherry tomato and spinach were used as planting crops for preliminary planting experiments. By setting different amounts of SRM being added into soil as experimental variables, the effect of coal measure natural minerals on plant growth in sandy soil was preliminarily discussed. Then continuous cultivation experiments were conducted to investigated the effects of SRM on the properties of plant (yield and quality) and soil (pH, enzyme activity, total nitrogen, alkali solution nitrogen, available phosphorus, cation exchange capacity, bio-enzyme activities) under continuous cultivation.
