Problems solved by technology

After searching, it is found that there is no report of using pig dung bean as banana green manure, and there are the following problems in planting green manure between banana orchards:
[0006] (3) In terms of returning green manure to the field, there is currently no clear statement on the cutting height of green manure;
[0007] (4) While returning to the field, most studies did not cut off the green manure, resulting in a long time for green manure to decompose, whether it was buried deep or covered and returned to the field, and the release of nutrients was blocked, which failed to achieve the expected effect;
[0009] (6) Most of the interplanting plants in the banana garden are short-term plants, which are only carried out in the new banana garden

Abstract

The invention discloses a method for cultivating and field returning of green manure crotalaria mucronata and application. The method for cultivating and field returning comprises the steps of selection of green manure, planting of the green manure, mowing of the green manure and returning of the green manure to the field. The method has the advantages that it is found that the crotalaria mucronata can be used as the green manure in banana intercropping planting, the number of fusarium oxysporum can be reduced in the growth process of the crotalaria mucronata, and the crotalaria mucronata hasthe prevention and treatment effect on banana wilt. According to the method, fine soil preparation before banana planting is not needed, and manual management is not needed after the crotalaria mucronata is planted, so that time can be saved, and unnecessary investment of manpower and material resources is reduced.

Description

technical field [0001] The invention belongs to the technical field of green manure cultivation, and in particular relates to a cultivation and returning method and application of green manure pig dung bean. Background technique [0002] Bananas are rich in antioxidants (vitamin A, vitamin B 6 , vitamin C, etc.) and minerals (potassium, nitrogen, phosphorus, calcium, magnesium, etc.) nutritious and healthy tropical fruit, one of the most important economic and food crops in tropical regions of the world. Bananas are one of the most nutritious export agricultural products and are widely grown in suitable tropical regions around the world. There are 120 countries in the world that grow bananas, and the planting areas are mainly distributed in tropical and subtropical regions between north and south latitudes of 30°. The annual output of bananas in the world is nearly 100 million tons, and the total output value is only behind rice, wheat, and corn. China is one of the main ...
