Synergistic cultivation method for intercropping symbiosis of open-field ginger and high-stalk corn

Abstract

The invention belongs to the technical field of ginger planting, and discloses a synergistic cultivation method for intercropping symbiosis of open-field ginger and high-stalk corn. The method comprises the following steps of applying a base fertilizer, removing impurities in the ginger land to be planted, and spreading a biological organic fertilizer, namely, sheep manure, a vegetable cake fertilizer and a compound fertilizer; carrying out soil tillage, carrying out mechanical tillage on the land applied with the base fertilizer, digging side ditches around the ginger field, carrying out deeptillage, hoeing and ploughing, and carrying out fine tillage on soil for later use; carrying out seed selection and germination acceleration, performing seed selection, seed sectioning, seed airing,disinfection, mesh bag loading and germination acceleration on the ginger seeds prepared in the last year in sunny days; sowing and planting ginger seeds, planting the ginger seeds subjected to germination acceleration in prepared sowing ditches, and covering an agricultural film for heat preservation and moisture preservation; intercropping corn in the ginger field, planting a row of high-stalk corn in the open ginger field, and shielding strong sunlight in summer through corn plants; and carrying out field management. The method can obviously avoid severe burn of ginger plant leaves caused by strong sunlight in midsummer, and obviously improve and optimize soil physicochemical properties and microbial population structure.

Description

technical field [0001] The invention belongs to the technical field of ginger planting, and in particular relates to a synergistic cultivation method for intercropping symbiosis of ginger and high-stalk corn in the open field. Background technique [0002] At present, open-field cultivation of ginger is the most widely planted in our country. Regardless of whether the ginger is planted in the north or the south, the edge and tip of the leaves of the plant will dry up due to the sun's strong light in midsummer. receive. Ginger has the biological characteristics of preferring partial shade and not being able to withstand strong light. Therefore, reasonable intercropping of high-stalk corn crops in the open field in midsummer can block part of the sunlight, which can effectively avoid damage to the leaves of ginger plants caused by strong sunlight in midsummer. , to ensure the normal growth of ginger, and to increase production and efficiency. [0003] Through the above analy...

AI Technical Summary

Problems solved by technology

[0003] Through the above analysis, the problems and defects of the prior art are: the existing ginger planting is severely damaged by the strong light in the midsummer season, which affects the normal growth of the plant and reduces the yield and economic benefits of the ginger.
