Abstract:
Test results of 1986-1987 indicated that the long-effect nitrogen fertilizer CDU from Japan had increased the yield of muskmelon significantly. In loam sandy soils, application of CDU convert to pure N 12kg/mu as basic fertilizer increased yield 10-l7% higher than that the equal amount of normal urea, and that the ratio of early maturing melons rose upto 80%, so there was a good economic effect. The results also showed that CDU could retard the growth of fungi, promote the growth of actinomyces, bacteria, azotobactria, and accelerate tne growth of the plant.
Key words:
