Experiment with Fertilization for Promoting Flowering and Fruiting in Pinus tabulaeformis Seed Orchards
摘要
Abstract
In order to provide technical support to the fertilizer program of Pinus tabulaeformis seed orchard,experiment with fertilizer use for Pinus tabulaeformis seed orchard was carried out in Luo-nan seed orchard of Shaanxi.The experiment applied different fertilization treatments for research u-sing orthogonal design L9=34 method.Field experiment was conducted with four factors at 3 levels each.The results showed that N(0.50 kg),P(1.00 kg),K(0.20 kg)and radiative fertilization method combined achieved the best,with the female flowers most in quantity.The key is the choice of fertilizer application method on Pinus tabulaeformis seed orchard.The effect of fertilizer on female flowers followed the order K＞N＞P.关键词
