Multiple cropping mode for improving drought resistance of mangoes in Leizhou region and restoring orchard soil fertility

Abstract

The invention discloses a technical mode for improving the drought resistance of mangoes in the Leizhou region and restoring the orchord soil fertility. The multiple cropping mode of mangoes and leguminous crops comprises the following steps: carrying out farrowing in a passage between mango rows, filling farrows with litchis fallen leaves, applying a liquid fertilizer, spraying a biological decomposition agent, planting the leguminous crops and applying a soil activation water-retaining agent. The technical mode mainly comprises the steps of carrying out furrowing in the middle passage of two rows of mangoes and planting the leguminous crops. According to the technical mode for improving the drought resistance of the mangoes in the Leizhou region and restoring the orchard soil fertility, the fertilizer utilization rate is increased by applying efficient liquid fertilizer; the decomposition of fallen leaves is accelerated by spraying the biological decomposition agent; a biological carbon source and a nitrogen source are jointly supplemented for soil by planting land-nourishing leguminous crops, so that the orchard soil fertility is restored; and by applying the soil activation water-retaining agent, the drought resistance of the mangoes in winter and spring is improved, finally, the yield and quality of the mangoes are improved, sustainable utilization of mango orchard cultivated land is achieved, and social benefits, economic benefits and ecological benefits are synchronously improved.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a multi-cropping mode of mango and bean crops for improving the drought resistance of mangoes and restoring the soil fertility of orchards. Background technique [0002] Introduction and efficacy of mango: Mango is native to southern China and has a history of more than 1,500 years in China. Mango belongs to Rutaceae, a small tree with a height of up to 12 meters. There are usually three kinds of sweet mango, sour mango and bitter mango. It is known as "Chinese famous fruit". Mango is rich in vitamin C, sugar, organic acid and pectin. . Mango roots, stems, leaves and fruits are treasures throughout the body, and different parts can be used as medicines, which have the functions of digestion and phlegm, regulating qi, relieving stagnation and heat, dispelling wind and relieving external appearance, and removing phlegm and promoting qi. Mango likes warm, humid and ...

Problems solved by technology

[0008] The multi-cropping model of mango and leguminous crops is used to solve the seasonal drought in winter and spring in Leizhou area proposed in the above background technology, compaction of rhizosphere soil in mango orchards, year-by-year decline in soil fertility, decline in root fertilizer absorption capacity, low yield and quality, and low profitability. Problems with poor traditional cultivation techniques
