Abstract:
The determination results of soil available phosphorus at different temperatures are greatly affected, in order to study the correlation between temperature and soil available phosphorus and the correlation coefficient. In this experiment, according to the determination method of available phosphorus in neutral and calcareous soil, the effect of different color rendering temperature on available phosphorus content in alkaline soil in northern China was studied. The results show that when the available P is measured, the suitable color temperature is 25∼30°C; At 25°C as the standard, the soil available P values reached a very significant positive correlation at different temperatures, and the correlation coefficients were 0.983 ** , 0.991 ** , 0.996 ** and 0.988 ** , respectively.
