| 摘 要： | 在实验室条件下,将不同比例的蚓粪施用于果园土和菜园土,研究蚓粪对玉米Zea mays生长和土壤肥力特征的影响.结果显示:施用蚓粪能够显著增加玉米株高、地上部和地下部的干质量、叶绿素SPAD值、植株地上部和地下部的全氮和全钾含量(P<0.05);施入10%蚓粪时,2种土壤中的玉米株高均达到最高水平;果园土和菜园土中分别施入5%和10%蚓粪时玉米干物质质量最大.施入20%蚓粪时,2种土壤植株地上部的全氮和全钾含量最多,地下部的全氮含量最多;蚓粪施入能够有效调节土壤pH;随着蚓粪比例的增加,2种土壤的有机质、碱解氮、有效磷以及速效钾的含量明显增高(P<0.05).主成分分析结果显示:2种土壤中,20%蚓粪处理土壤肥力综合特征均显著区别于对照处理(P<0.05).蚓粪可以作为一种环境友好肥料应用于作物生产和土壤培肥,根据不同土壤特征,利用多种农业有机废弃物生产蚓粪,并选择适宜的蚓粪比例进行农业生产,有利于农业的可持续发展.

| Abstract: | Microcosm experiment was conducted to evaluate the effects of vermicompost at different proportions on the growth of Zea mays and soil fertility in orchard and vegetable soil. The results showed that significant increases were observed in the height, the aboveground and underground biomass, chlorophyll SPAD, total N and K uptake in aboveground and underground parts of Z. mays with the addition of vermicompost (P<0.05).The height of Z. mays was at the highest level of 10% vermicompost in these two types soil. The aboveground and underground biomass were the maximum at the level of 5% vermicopmpost in the orchard soil and 10% vermicompost in garden soil, respectively. When the proportion of vermicompost was 20%, total N and K contents uptake in aboveground parts and total N uptake in underground parts of Z. mays were more remarkable than others. In addition, vermicompost adjusted soil pH. Contents of soil organic matter, available N,P and K increased significantly with the increasing ratio of vermicompost in soil (P<0.05). Principal component analysis showed significant differences in soil fertility between 20% vermicompost and control treatments in two types of soil. As a kind of environmental friendly fertilizer,the study confirmed the promise of vermicompost on crop production and soil fertilization. In the future, it is necessary to produce vermicompost by various agricultural organic wastes and perform suitable proposition of vermicompost according to soil properties. |
