4·抓住季节,科学施肥杨梅具有菌根,其根部有放线菌共生形成根瘤,具有固氮能力,对磷肥反应敏感,单独使用磷肥或过量施磷时,极易引起缺硼、缺锌及缺钼症状。故杨梅施肥应注重使用钾、氮和适量的硼、锌、锰等微量元素。应根据梯田或坡地的具体条件,采用在树冠外围直下开环沟、长 4. Grasping the season, scientific fertilization Myrica rubra has mycorrhizal roots with actinomycetes symbiotic formation of nodules, with nitrogen fixation capacity, sensitive to the phosphate fertilizer, phosphate alone or excessive phosphorus, can easily lead to boron deficiency, zinc deficiency and Molybdenum symptoms. Therefore, Yangmei fertilizer should pay attention to the use of potassium, nitrogen and appropriate amount of boron, zinc, manganese and other trace elements. Should be based on the specific conditions of terraces or slopes, the use of open-loop ditch in the crown periphery, long
