The effect of microbial bacteria on biomass accumulation and physiological characteristics of feed watermelon
By setting the microbial dosage at 5 levels of 0,4,8,16 and 32 g/plant,the effects of different microbial dosage on biomass accumulation,carbon and nitrogen metabolism enzyme activity,quality,and yield indicators of feed watermelon were studied.The aim was to provide theoretical basis for improving the quality and efficiency of watermelon cultivation and providing high-quality raw materials for new feed processing.The results showed that microbial strains could promote the accumulation of biomass in feed watermelon,but the effects of different concentrations of microbial strains on the accumulation of biomass in feed watermelon varied.Microbial bacteria increased the activities of sucrose phosphate synthase,sucrose synthase,glutamine synthase,nitrate reductase,and glutamate dehydrogenase,with the highest activity observed under FM3 treatment,which increased by 13.08%,16.17%,29.38%,28.03%,and 32.11%compared to the control,respectively,with significant differences(P＜0.05).With the increase of microbial dosage,the central soluble solids,vitamin C content,and average single melon quality all showed a single peak curve change pattern of first increasing and then decreasing.Moreover,under MF3 treatment,the above index values were higher,increasing by 17.04%,24.48%,and 22.53%compared to the control,respectively;The organic acid content and skin thickness show a"U"curve pattern of first decreasing and then increasing,with the minimum value under MF3 treatment.The correlation analysis showed that there was a highly significant(P＜0.01)positive correlation between the main stem diameter,main vine length,and leaf area with the central soluble solid content,vitamin C content,and average single melon quality.
