Abstract:

In order to select suitable mulching materials for watermelon cultivation, four different materials (white film, mushroom residue, liquid film and black grass control non-woven fabric) were selected for mulching cultivation, and their effects on nitrogen metabolism, yield and quality of watermelon were comprehensively compared. The results showed that: (1) among all the treatments, the mulching effect of black grass control non-woven fabric was the best, the fruit yield, and the content of soluble solid and Vc were significantly higher than those of other treatments; the contents of total nitrogen and soluble protein in leaves were significantly or extremely significantly higher than those of other treatments, so were the activities of nitrate reductase (NR), glutamine synthetase (GS) and glutamate dehydrogenase (GDH); (2) the correlation analysis showed that the yield of watermelon under different mulching treatments was significantly and positively correlated with total nitrogen content and extremely significantly and positively correlated with NR activity; there was a significantly positive correlation between total nitrogen content and NR activity, and an extremely significantly positive correlation between total nitrogen content and GS and GDH activities. The results showed that the black grass control non-woven fabric could be used as a suitable mulching material for watermelon cultivation.
