为了更好地克服草莓连作障碍,在江苏省盐城市田间进行蚯蚓粪用量试验。设置蚯蚓粪用量分别为15、20、25、30和35吨/公顷,以不施用为对照,比较草莓的生长情况和土壤性质的变化。结果表明,蚯蚓粪为20吨千克/公顷时效果最好,土壤pH为6.02,总盐分值为996.71毫克/千克,除硝酸盐以外,各离子含量及养分值均适合草莓的营养需求,草莓长势最佳,产量最高。
In order to better overcome the cropping obstacle in strawberry farming, the amount of vermicompost was tested in the field of Yancheng, Jiangsu Province. The dosage of vermicompost was set at 15, 20, 25, 30 and 35 t / ha, respectively. Compared with the control, the growth of strawberry and soil properties were compared. The results showed that the earthworm excrement was the best when it was 20t kg / ha. The soil pH was 6.02 and the total salinity was 996.71 mg / kg. The contents of ions and nutrients except for nitrate were suitable for the nutritional requirements of strawberry, Strawberries grow best and produce the highest.
