袋控缓释条件下硝态氮、铵态氮对桃尿素吸收、分配的影响
Effect of NO3- -N and NH4+ -N on Urea Absorption and Distribution in Peach under Coated Controlled Release Conditions
摘要
Abstract
Taking Dahlia pinnata variety Shenmeihong as material, the effects of formulated fertilization with N, P and K on its growth and development and the nutrient contents in leaves and soil were studied through pot experiment with "3414" incomplete regression -orthogonal design. The results indicated that all the fertilization treatments improved the number of total flowers, petals and functional leaves significantly. The effect of N3P2Kj treatment was the best. Different fertilization treatments had different effects on the content of N, P and K in leaves. The single factor analysis indicated that fertilization improved the contents of N, P and K significantly in leaves. Compared with the control, the content of available nutrients in soil increased in different degree.关键词
