Leaf beet plant factory cultivation method

Abstract

The invention discloses a leaf beet plant factory cultivation method which includes the steps of seed treatment, germination accelerating, sowing, cotyledon growth, seedling culture, field planting, harvesting and the like. Weather and light environments are simulated by a plant factory, leaf beet cultivation breaks away from limitation of soil, temperature, regions and seasons, and annual uninterrupted production is realized. Seeds are treated by H2O2 and low temperature, the seed germination rate of leaf beets can be increased from 50-65% to 85% or more, germination potential is improved from 30-50% to 80% or more, and the problem of seed germination irregularity is solved. The yield of the leaf beets can be improved by the aid of staged nutrient solution and illumination regulation, andgrade and flavor are improved. Two commodity types of the leaf beets can be planted, one-time and repeated leaf separation harvesting modes are provided, by the aid of repeated leaf separation harvesting, seed cost can be reduced, harvesting time can be shortened, the yield can be improved, and manpower and material resources are saved.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a plant factory cultivation method of leaf beet. Background technique [0002] Leaf beet (Bata vulgaris L.var.cicla L.) English name is leaf beet, Swisschard, also known as chard, beet, and thick-skinned vegetable. It is a biennial herb of the Chenopodiaceae Beet genus. There are four types of white stalks, green stalks, yellow stalks and red stalks. They are high-quality crops for food, medicine and appreciation. They are sweet in taste and cool in nature. It can help improve appetite, relieve headaches, prevent colds and anemia. It is widely distributed in the Yangtze River, Yellow River Basin and Southwest my country in central China. The edible method is mainly based on small seedlings and large leaves. In recent years, red leaf beet, red stalk beet, whole red beet and yellow stalk beet are popular as special vegetables at home and abroad for their bright...

Problems solved by technology

[0004] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved in the present invention is to provide a plant factory cultivation method of leaf beet, which specifically adopts the plant factory planting mode for cultivation, and utilizes H 2 o 2 And low temperature treatment can solve the problem of low germination rate and irregular germination, increase the germination rate of leaf beet seeds from 50-65% to more than 85%, and increase the germination potential to more than 80%, which greatly reduces the risk of seed and sowing The cost is conducive to the cultivation of strong seedlings, improving the quality and yield of products; the plant factory simulates the climate and light environment, and regulates the nutrient solution in stages, which solves the limitation of soil, season and temperature in the open field cultivation of leaf beet, which is different from timely topdressing cumbersome, no pesticides, no heavy metals, safe, stable, annual planned production, which is conducive to efficient absorption of plants, nutrient enrichment, rapid growth, and cost reduction. The product has excellent appearance and flavor, and meets the market demand for leaf sugar The present invention can also realize the planting of two kinds of commodity types of leaf beets, and can also realize one-time harvesting and multiple leaf-covering harvests of leaf-use beets, one-time harvesting helps to ensure the quality and mouthfeel of leaf beets, and repeatedly Leaf harvesting is beneficial to reduce seed, labor and land costs, shorten harvest time and increase yield
