Abstract

The invention discloses a method for interplanting chrome-rich hylocereus undatus and chrome-rich dioscorea esculenta. The method comprises the steps of cultivated land selection, ridging and pillar setting up, planting, management and fertilization, pinching and pollination, harvesting and the like; according to the method for interplanting the hylocereus undatus and dioscorea esculenta, a planting mode of the interplanting of the chrome-rich hylocereus undatus and chrome-rich dioscorea esculenta is adopted, the competition for light, temperature, water and fertilizer between the hylocereus undatus and the dioscorea esculenta is little, the ground coverage is increased after interplanting is performed, weeds can be controlled, the root system of the dioscorea esculenta can also loosen soil, thereby improving the physical and chemical properties of the soil and being conductive to the growth of the hylocereus undatus. The method for interplanting the chrome-rich hylocereus undatus andchrome-rich dioscorea esculenta has the advantages that the average content of total chrome in the chrome-rich hylocereus undatus and chrome-rich dioscorea esculenta reaches the standard of chrome-rich food, and the hylocereus undatus and dioscorea esculenta have a significant economic effect; in addition, the planting density of the dioscorea esculenta and hylocereus undatus can be arranged reasonably, the land is utilized scientifically, the land utilization rate is improved, pesticide and fertilizer are saved, and the method has a positive effect on environmental friendliness, conforms to economic production, is suitable for popularization in agriculture and has a good popularization prospect.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a method for interplanting chromium-rich dragon fruit and chromium-rich sweet potato. Background technique [0002] Chromium is an essential trace element for the human body. Although hexavalent chromium is toxic, trivalent chromium is a component of glucose tolerance factor and one of the trace elements necessary for humans and animals to maintain normal glucose metabolism and lipid metabolism. The main biological functions of trivalent chromium include the following aspects: (1) participate in glucose metabolism; (2) participate in lipid metabolism and maintain blood cholesterol balance; (3) participate in the synthesis of protein and nucleic acid; (4) regulate animal Mineral metabolism in the body. Among trivalent chromium products, organic trivalent chromium chelates have higher biological activity. Organic chromium affects the metabolism of sugar, fat, minerals and pro...
