不同种养模式对椰园土壤养分的影响
Effects of Different Modes of Planting and Feeding on Soil Nutrients in Coconut Plantations
摘要
Abstract
Through the test of different modes of planting and feeding in coconut-garden fields, the influence of three different modes of planting and feeding, intercroping grass and feeding Wenchang chickens, intercroping grass and feeding goats, feeding chickens and intercroping weeds in natural coconut -garden fields, on soil nutrients were studied. The results showed that: (l)In these three modes of planting and feeding, by comparing the control soil with the sample soil, different modes of planting and feeding had certain influence on the soil pH, the mode of intercroping grass and feeding chicken had significant influence on soil pH, the other two modes had little influence on soil pH. (2)The soil organic matter was higher in the mode of planting and feeding than that of control soil, and the soil organic matter in the mode of intercroping grass and feeding chickens was significantly higher than that of other modes, the soil organic matter in the mode of intercroping weeds and feeding chickens and in the mode of intercroping grass and feeding goats had slight difference with that of the control soil. (3)In different modes of planting and feeding, the content of available N, available P, available K of the top soil from 0 to 20 cm in the different modes of planting and feeding increased significantly compared with that of the contol soil, the nutrients in top soil from 20 -40 cm did not change in all the situations.关键词
