Abstract

In order to investigate the accumulation of dry matter and NPK nutrients in Moringa oleifera, the whole plant mastication method was used to study the dynamic changes in the dry matter and nutrition accumulati0ns of whole plants and organs (root, stem, leaf and fruit pod) at different times after planting of annual saplings. The results showed that the annual dry matter and NPK accumulation of Moringa oleifera saplings were 2.29 kg/plant, 27.05 g/plant, 8.64 g/plant and 60.46 g/plant, respectively, and the nutrient accumulation and nutrient accumulation were: potassium> Nitrogen > phosphorus. The accumulation of Moringa oleifera dry matter and NPK nutrients were divided into the cumulative slow phase before 100 days of colonization, the cumulative acceleration phase from 100 days after planting to pre-flowering and the rapid accumulation stage of flowering to fruit pod maturity. And the dry matter and NPK nutrient accumulations mainly distributed in roots and stems, but leaf dry matter and NPK nutrient accumulation are not high. During the ripening of the fruit pods, the dry matter of the pods and the NPK nutrients accumulate rapidly. Therefore, in the production of Moringa oleifera, the application of nitrogen and potassium fertilizers should deserves attention, and it is necessary to carry out cultivation management according to different needs in order to obtain high-yield fruit pods or leaves.
