求翻译：所以我们选取了1个点进行原生盐碱地微生物群落多样性研究，3个点进行次生盐碱地微生物群落多样性研究，Plot 5.为农田土，作为土壤对照。是什么意思？

Therefore, we selected a point of saline-alkali soil microbial community diversity in native and three points in the secondary saline-alkali soil microbial community diversity, plot 5. Farmland soil as a soil control.

Therefore, we selected a 1-point saline microbiological communities native biodiversity research, 3 points for microbiological communities nocturnal saline Plot diversity studies, 5, and to field as soil.

Therefore we selected 1 spot to conduct the primary saline and alkali land microflora multiplicity research, 3 spots conducted the secondary saline and alkali land microflora multiplicity research, Plot 5. are the farmland earth, took the soil comparison.

So we select one primary research on saline-alkali soil microbial community diversity, 3 points for secondary saline soil microbial community diversity, Plot 5. farmland soils, soil control.
