Effect of new humic acid fertilizer on the growth,yield,and quality of melon
To investigate the application effects of four new types of humic acid fertilizers,a field experiment was conducted using the melon variety Nongdatian 8 as the test material to study its effects on the growth,yield,and quality of the melon.The results showed that compared with the clear water control(CK),all new fertilizers increased melon yield to varying degrees.Among them,HK08 fertilizer had the most significant application effect,increasing yield by 22.22%compared with CK.At the same time,this fertilizer can significantly improve the intrinsic nutritional quality of melon and promote the above ground growth of melon.In summary,the application of HK08 fertilizer can effectively promote the improvement of melon quality and income,and it is recommended to carry out large-scale promotion and application.
