Treatment method for preventing soil salinization in greenhouse strawberry continuous-cropping land blocks

Abstract

The invention designs a planting management method, and concretely relates to a treatment method for preventing soil salinization in greenhouse strawberry plant continuous-cropping land blocks. In particular, at beginning of April and beginning of September each year, ipomoea aquatica of which the seedling height is 40cm-50cm is transferred out from an original planting environment, cutting is performed for fixing the treated ipomoea aquatica into plug trays, the fixed ipomoea aquatica is transplanted into furrows under ridges, when seedlings of the ipomoea aquatica are grown to a height of 70-80cm, the grown ipomoea aquatica and the plug trays are moved out from places under the ridges, alcohol extraction is performed on the harvested ipomoea aquatica, and an organic alkali component is obtained, after the component is diluted, at middle ten days of December and middle ten days of May each year, the ipomoea aquatica extractive is diluted by a factor of 100-120, and the diluted extractive is sprinkled to strawberry plant root systems. The treatment method for preventing the soil salinization in the greenhouse strawberry plant continuous-cropping land blocks is simple, treatment labor intensity is low, treatment points are arranged under the strawberry planting ridges, thus the method has no influence on growth of strawberry plants on the ridges, after treatment, salinity in greenhouse soil is remarkably reduced, and the method has a remarkable effect on preventing the soil salinization in the strawberry plant continuous-cropping land blocks.

Description

technical field [0001] The invention designs a planting management method, and in particular relates to a treatment method for preventing soil salinization of strawberry continuous cropping plots in greenhouses. Background technique [0002] Strawberries are sensitive to the external environment, especially the salinity of the soil. Therefore, suitable temperature and humidity and a healthy soil environment are the keys to producing high-quality strawberries. A large amount of fertilizer is often applied during the planting period, and most of the unabsorbed part remains in the soil, resulting in nutrient enrichment and excessive soil salinity. The poor soil environment is a great resistance for strawberries to absorb nutrients and water, which is directly manifested in the strawberry planting period. Phenomena such as slow seedlings, easy dead seedlings, short plants, stunted growth, severe withering and death, and decline in yield and quality appear. This phenomenon is par...

[0002] Strawberries are sensitive to the external environment, especially the salinity of the soil. Therefore, suitable temperature and humidity and a healthy soil environment are the keys to producing high-quality strawberries. A large amount of fertilizer is often applied during the planting period, and most of the unabsorbed part remains in the soil, resulting in nutrient enrichment and excessive soil salinity. The poor soil environment is a great resistance for strawberries to absorb nutrients and water, which is directly manifested in the strawberry planting period. Phenomena such as slow seedlings, easy dead seedlings, short plants, stunted growth, severe withering and death, and decline in yield and quality appear. This phenomenon is particularly obvious in strawberry continuous cropping plots. The current solution is mainly after the strawberry fruiting period ends. , remove the strawberry plants and prepare the land, sow other crops, such as corn, to absorb the residual nutrients in the soil. After the adsorption period is over, replant the next crop of strawberries; the disadvantage of this method is that the strawberry plants need to be removed from the field and replanted Planting new crops for adsorption, and re-planting new crops after the adsorption is completed, which is labor-intensive
