Lettuce cultivation method

Abstract

The invention relates to the technical field of agriculture, and especially relates to a lettuce cultivation method. With the method, lettuce plant is robust, and pest and disease resistances are high. The method is suitable for areas with medium or low fertility. The lettuce cultivation method is characterized in comprising the following steps: (1) lettuce seedling-raising and transplanting are carried out; (2) seed low-temperature treatment is carried out, wherein seeds are wrapped with a gauze, and are placed at a shaded place at a water tank; (3) sowing is carried out. For spring lettuce the seedlings of which are raised in a greenhouse, a film on a seedling plot is opened; sufficient bottom water is applied; when water penetrates into soil, the seeds are doped with a small amount of fine sand or fine soil, and the well mixed mixture is sowed in a broadcast way; (4) reasonable close planting is carried out. Lettuce has high fertilizer demand, such that high fertility should be maintained, and loam should be loosened; and (5) fertilizer is applied with water, wherein the fertilizer is dissolved first, and then applied into the field with water.

Description

technical field [0001] The invention belongs to the field of agricultural technology, in particular to a cultivation method of lettuce. Background technique [0002] Lettuce is a kind of lettuce that mainly uses stems and leaves. Its stems are as big as bamboo shoots, so it is called lettuce.

It can enhance gastric juice, stimulate digestion, increase appetite, and has analgesic and hypnotic effects. It is a very common edible vegetable. The content of carbohydrates in lettuce is low, while the content of inorganic salts and vitamins is rela...

Problems solved by technology

[0003] It can be seen that lettuce can not only be used as a food material, but also has medicinal properties. However, the existing lettuce planting methods are not perfect enough. The planting yield of lettuce in high-fertility areas is very high, but the growth of lettuce in low- and medium-fertility areas is not satisfactory. emaciated and have reduced resistance to pests and diseases
