Condition in the Greenhouse Based on the Entropy Evaluation Method

Abstract

Xunbo Zhou*

When developing an appropriate agricultural water conservation project, numerous plant-soil system indicators should be considered. The entropy evaluation method has great potential for improving agricultural management strategies. The tomato was used as the plant material to investigate the effect of different buried depths of subsurface drainage pipes (30, 45, 60, 75, 90, and 105 cm) on greenhouse plant-soil systems. The tomato's marketable yield, fruit sugar to acid ratio, soil electrical conductivity, nitrogen loss rate, and crop water and fertilizer use efficiency were all observed. The entropy evaluation method was used to choose the best buried depth for subsurface drainage pipes based on these indicators. Tomato yield and soil electrical conductivity had comprehensive weights of 0.43 and 0.34, respectively, in both the objective and subjective weights calculations, indicating that they were more important than other indices.
