不同施肥方式对枣园土壤及叶片养分含量的影响
Effects of Different Fertilization on Soil Nutrient Content and Leaves in Jujube Orchard
摘要
Abstract
[Objective] This paper aims to explore the effects of different methods of fertilization on soil nutrient absorption of jujube and root in order to provide a theoretical reference for the efficient fertilization technology of jujube.[Method]Four different methods of fertilization ( furrow fertilization, hole fertilization, radial fertilization and broadcast fertilization) were used. The content of organic matter, nitrogen, phosphorus and potassium in soil were determined regularly, the content of total nitrogen, total phosphorus and total potas-sium were measured during fruit enlargement period and mature period to analyze the effects of different fertili-zation on absorption and utilization change of soil nutrients in jujube orchard.[Result]Different methods of fertilization could promote the improvement of soil fertility, the influence on the 0-20 cm soil layer was more obvious, and radial fertilization was the most significant. The effect of radial fertilization on the content of or-ganic matter was the most significant, and the furrow fertilization was the second during the whole growth cycle of red jujube. Furrow fertilization, hole fertilization and radial fertilization could significantly improve the soil total nitrogen content, the radial fertilization was the most significant, compared to CK, it increased by 0. 18 g/kg and 12. 66 mg/kg respectively. Furrow fertilization, hole fertilization and radial hole fertilization had sig-nificant effects on soil available phosphorus and available potassium content, the influence of hole fertilization on soil available phosphorus was the most significant, compared with CK, it increased by 26. 38 mg/kg. The effect of radial fertilization on quick effect potassium was the most significant;it increased by 81 mg/kg. The four methods of fertilization had significant effects on the content of phosphorus in leaves. Radial fertilization and hole fertilization had significant effects on contents of nitrogen and potassium in leaves, the effects of radial fertilization on the changes of nitrogen, phosphorus and potassium contents were the most significant.[Conclu-sion]The application of radiation fertilization can effectively increase the soil nutrient content and obviously improve the nutrient absorption effect of the leaves.关键词
