Cultivation method for interplanting of sweet corn in mangifera indica L. orchard and crop rotation of sweet corn and sweet and crispy pisum sativum L

Abstract

The invention discloses a cultivation method for interplanting of sweet corn in a mangifera indica L. orchard and crop rotation of the sweet corn and sweet and crispy pisum sativum L. The method comprises the following steps of selection of a planting area, planting of mangifera indica L., interplanting of the sweet corn in the mangifera indica L. orchard and crop rotation and harvesting of the sweet corn and the sweet and crispy pisum sativum L, application of base fertilizer, disease and pest prevention and control and topdressing. According to the method, through interplanting of the sweet corn among the lines in the mangifera indica L. orchard and the crop rotation of the sweet and crispy pisum sativum L from the first year to the third year after field planting of mangifera indica L. seedlings, the utilization rate of the land is significantly increased, the economic income per unit area is increased, the management cost and production cost are reduced, and the cultivation method achieves high efficiency and high yield.

Description

technical field [0001] The invention relates to a cultivation method for interplanting sweet corn in a mango orchard and a crop rotation between sweet corn and sweet snap peas, and belongs to the technical field of ecological agriculture. Background technique [0002] Mango (Mangifera indica L.) is one of the famous tropical fruits. The fruit is rich in sugar, protein, crude fiber, vitamin A, vitamin C, minerals, protein, fat, sugar and so on. It can be made into juice, jam, canned food, mango milk powder, candied fruit, etc. It is a tropical fruit that people like to eat. The tropical and subtropical high-wind climate area in Yunnan has many mountains, obvious three-dimensional climate, sufficient sunlight, high temperature throughout the year, and distinct dry and wet seasons. It is a suitable area for the production of mangoes, soybeans, and chives. However, in the young stage of mango trees (within 1 to 3 years after planting), there is only input for a single mango in ...

Problems solved by technology

[0004] Yunnan mountainous orchards have fragile ecology, soil degradation, and soil nitrogen and phosphorus shortage. In the young fruit tree stage, if the simple application of nitrogen and phosphorus fertilizers is not only ineffective in increasing their growth, but also results in low fertilizer utilization efficiency, increased costs, and land compaction. , the soil environment is getting worse

If the mango orchard is simply interplanted with sweet snap peas, first, the roots of the peas can secrete a large amount of organic acids, which will increase the acidity of the soil, affect the development of pea rhizobia in the next year, and aggravate the occurrence of diseases and insect pests (root rot, powdery mildew, etc.), resulting in The subsequent crop of peas does not grow well or the seedlings are dead. Second, after continuous cropping, the plants absorb more phosphorus and potassium fertilizers, which tends to make the soil barren and affect the normal growth and pod formation of the subsequent crop of sweet snap peas.
