【摘要】 选择缺钙土壤旱沙土进行不同治秕物料防治花生空秕效果的试验,试验采用裂区设计,设2因素,3次重复。结果表明,在旱沙土上种植花生,施用贝壳粉和钙镁硫配方肥,比对照分别增产50.41%、42.15%,增产均达到极显著性水平。施用贝壳粉的干果产量高于钙镁硫配方肥,并达到显著性差异。贝壳粉是较理想的防治花生空秕的钙肥品种,贝壳粉的适宜用量是每公顷1500 kg。更多还原

【Abstract】 Choosed the dry sandy soil lacked of calcium to test the effect on the control of sterile grain of peanut by different materiel.The test used split-plot design for 2 factors and 3 times to repeat.The results showed that the dry sandy soil under peanut cultivation,applied shell powder and formula fertilize fused calcium-magnesium sulfur,than that of the control,increased 50.41% and 42.15% respectively.Nut yield of shell powder application was higher than that of the formula fertilize,and achieved significant difference.Shell powder was the better calcium fertilizer vatiety to control of sterile grain of peanut,and its appropriate dosage was 1500 kg per hectare.更多还原
