Problems solved by technology

[0003] Under the cultivation technology at the present stage, lettuce is easily eroded by pests, resulting in low survival rate of lettuce, decline in quality, high maintenance cost, resulting in high investment risk and low economic benefit. Therefore, it is urgent to develop a plant with high survival rate and fast production speed. , planting method with low investment cost

Embodiment 1

[0016] A hydroponic method for lettuce, specifically comprising the following steps:

[0017] (1) Preparation before sowing: choose a loose 3cm-thick sponge, cut it into small cubes of 3cm×3cm, clean the sponge piece with clean water, and lay it flat on a dry and watertight seedling tray;

[0018] (2) Seed treatment: select seeds with high-quality appearance and full grains, wash them, put them in the sun to dry until the surface of the seeds is dry and free of moisture, and then put them in copper sulfate with a mass fraction of 0.2-0.3% at a temperature of 25-28°C Soak in the solution for 3-5 minutes; take it out, wash and drain, and finally soak in warm water at 38-45°C for 12-14 hours;

[0019] (3) Sowing: Spread the soaked seeds directly on the surface of the sponge block, put 2-3 seeds on each block, and then add enough water to the seedling tray until the sponge block is soaked;

[0020] (4) Seedling stage management: put the seedling tray in a cool place after sowing,...

Embodiment 2

[0026] The difference between embodiment 2 and embodiment 1 is that the parts by weight of raw materials in the nutrient solution are different, and the others are the same.

[0027] The nutrient solution is composed of the following raw materials: 0.5 parts of calcium nitrate, 0.2 parts of ammonium nitrate, 3 parts of potassium dihydrogen phosphate, 0.6 parts of magnesium sulfate, 0.15 parts of potassium iodide, 0.5 parts of boric acid, 0.12 parts of manganese sulfate, 0.05 parts of zinc sulfate, 0.12 parts of sodium molybdate, 0.08 parts of copper sulfate, 0.12 parts of cobalt chloride, 0.16 parts of vitamins, and 120 parts of purified water.

Embodiment 3

[0029] The difference between embodiment 3 and embodiment 1 is that the parts by weight of the raw materials in the nutrient solution are different, and the others are the same.

[0030] The nutrient solution is composed of the following raw materials: 0.4 parts of calcium nitrate, 0.2 parts of ammonium nitrate, 3 parts of potassium dihydrogen phosphate, 0.6 parts of magnesium sulfate, 0.15 parts of potassium iodide, 0.5 parts of boric acid, 0.12 parts of manganese sulfate, 0.05 parts of zinc sulfate, 0.12 parts of sodium molybdate, 0.08 parts of copper sulfate, 0.12 parts of cobalt chloride, 0.16 parts of vitamins, and 120 parts of purified water.

Abstract

The invention provides a water lettuce culture method. The water lettuce culture method comprises the specific steps of preparation before sowing, seed treatment, sowing, seedling stage management, planting and water culture management. The water lettuce culture method effectively improves the germination rate and disease resistance of seeds, can make the survival rate of transplanted lettuces above 92% and make the growing lettuces reach a best state by effectively controlling potential of hydrogen, temperature, moisture, lighting, nutrients, air and other conditions in the lettuce growing process, the problems of long lettuce growth time, low survival rate, susceptible plant diseases and insect pests, high production cost and the like are solved, and rapid industrialized planting is achieved.

Description

technical field [0001] The invention relates to the field of planting, in particular to a hydroponic method for lettuce. Background technique [0002] Lettuce (var. ramosa Hort.) Commonly known as lettuce for leaves, also known as goose vegetable, star vegetable, and lettuce, it belongs to the genus Lactuca of Asteraceae. It is an annual or biennial herb crop. The leaves are long obovate and densely formed into cabbage-like leaf balls. It can be eaten raw, crisp, tender and refreshing, and slightly sweet. Lettuce can be divided into green lettuce and purple lettuce according to the color of the leaves; if it is distinguished according to the growth state of the leaves , There are two kinds of loose-leaf lettuce and head lettuce; the former leaf lettuce is made into loose pieces, and the latter leaves are embracing into a ball. If it is further subdivided, there are three types of head lettuce. One is butter lettuce with obovate leaves, smooth leaves, soft texture and slight...
