红富士苹果在中国引种已经10多年了，为促进树体单位干周截面积上形成适当的枝条数量，增加优质果品的生产，合理负载是其优质丰产的一个技术关键。本试验通过对红富士苹果树增施一种新型纯生物有机肥，观察研究树体单位干周截面积上枝条形成的情况和效应。l材料和方法“新农”
Red Fuji apple introduced in China for more than 10 years, in order to promote the formation of appropriate number of branches on dry week cross-sectional area and increase the production of high-quality fruit, reasonable load is a key technology of high yield and good quality. In this study, a new type of pure bio-organic fertilizer was applied to Red Fuji apple trees to observe the situation and effect of shoot formation on the dry-week cross-sectional area of the tree body. l Materials and Methods “New Farmers”
