Planting method of asparagus lettuce for preventing buried decaying

Abstract

The invention provides a planting method of asparagus lettuce for preventing buried decaying. The method mainly comprises eight steps of seed collecting and preparing, seed processing before sowing, turning soil, sowing and seeding, fertilizing and watering, root-protected colonizing, performing field management, controlling diseases and pests, and harvesting. Through interplanting broad beans attwo sides of a crop planting land, a heat insulating effect of the asparagus lettuce can be improved through interplanting, thereby resisting cold storms, improving yield and quality of the asparaguslettuce and preventing asparagus lettuce hollowing caused by low temperature. Furthermore, through planting the asparagus lettuce at the middle part, uniform temperature of the integrally planted asparagus lettuce can be promoted, thereby preventing missing of a high-price period caused by different to-market time points. Furthermore the asparagus lettuce planted according to the planting method has advantages of relatively small size, small number of defects of center hollowing and stalk decaying, and effective market competitiveness improvement.

Description

technical field [0001] The invention mainly relates to the technical field of crop planting, in particular to a planting method for preventing and controlling lettuce buried in the ground and rotting. Background technique [0002] Lettuce, also known as lettuce, is a biennial herb that can form fleshy tender stems. Alias ​​lettuce for stems, lettuce shoots, green shoots, lettuce.

Problems solved by technology

[0003] In the existing crop planting process, due to the influence of the soil quality of the lettuce and the influence of the application of fertilizers, not only will the part of the lettuce buried deep in the ground rot, but at the same time, when the rotten part of the lettuce is not treated for a long time in the ground, it will The breeding of harmful substances not only affects the growth of other crops around, but also affects the land of the entire land, shortening the life of land recycling
