摘要
1986—1987年用长效氮肥CDU对伊利莎白甜瓜进行施肥试验,其增产效果显著,在砂壤质土壤上,一次亩施折合纯氮12公斤的CDU作基肥,比施用等氮量尿素增产10—17%,前期瓜产量提高80%以上,经济效益良好.同时研究确认CDU有抑制土壤真菌,促进放线菌、细菌和自生固氮菌的数量增加,有利于作物的健壮生长.
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-l%higher than that tne equal amount of normal urea, and that the ratio of early maturing melons rose upto80%, 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.
