枇杷之營養管理(I)

Plant Nutrition and Soil Management of Loquat (I)

摘要


經營枇杷園最重要的工作為維持營養生長與生殖生長間之平衡,而控制氮肥可能是調整植株使符合經濟生產的最好方法。氮肥影響及結果枝枝條的長度、葉數等甚為明顯,故其主要角色在引導植株之營養生長;而磷肥對果實有增酸的效果,鉀肥有促進果實肥大的效果,但皆未達顯著水準。為求得適當的葉片採樣時期及訂定各元素在葉片之適宜濃度,藉以實施營養診斷以便進行肥培管理等推荐工作,有必要實施長期密集的每月採樣,同時分析其礦物元素與碳水化合物之含量,並求得其間與果實品質產量之相關研究。

The-most important work in loquat production is to maintain the balance between vegetative and reproductive growth of plants, Nitrogen played significant roles in vegetative growth especially for shoot and leave growth. Phosphorous raised fruit acidity and potash could increase fruit size. For better understanding the most appropriate sampling stage and the optimun range of the nutrients, it is necessary to sample leave and shoot monthly for diagnosis and fertilizer recommandation. It is also important to find the relationships between plant nutrients, carbohydrate content on the fruit yield and quality.
