Sunlight greenhouse pollution-free seedling growing method for broccoli

Abstract

The invention discloses a sunlight greenhouse pollution-free seedling growing method for broccoli. The sunlight greenhouse pollution-free seedling growing method comprises the following steps: preparing a seedling bed, treating seeds, sowing, performing seedling growing management, managing cultivation soil, planting, performing cultivation management and harvesting. Compared with the prior art, the sunlight greenhouse pollution-free seedling growing method has the advantages that raw materials in a seedling growing medium are all green pollution-free raw materials which are wide in source, nutrient substances can be effectively provided, and meanwhile phenomena that seedlings are burnt because of overnutrition, and the like can be avoided; due to addition of a boric fertilizer, a molybdenum fertilizer, a selenium fertilizer and the like in cultivation management, growth of plants and the quality of broccoli can be improved, the content of nutrient elements in broccoli can be increased, growing conditions of seedling growing and cultivation periods can be strictly controlled, the rate of strong seedlings of broccoli is high, the yield can be increased, the amount of resistance medicines can be reduced, and pollution-free planting can be achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a pollution-free seedling raising method for broccoli in a solar greenhouse. Background technique [0002] Broccoli is rich in nutrients, not only high in content, but also full of nutrients, including protein, carbohydrates, fat, minerals, vitamin C and carotene, etc., which can sterilize and prevent infection, and can also prevent cancer and fight cancer. , With the improvement of people's living standards, they are gradually starting to pay attention to healthy diet. The method of growing broccoli is relatively simple, so it has been planted on a large scale in greenhouses, but the current planting method only focuses on increasing the output of broccoli. Low-cost planting often easily leads to the decline of broccoli nutrition. At the same time, in order to effectively prevent and control diseases and insect pests in the growth process of broccoli, a...

Problems solved by technology

[0002] Broccoli is rich in nutrition, not only high in content, but also comprehensive in nutrition, mainly including protein, carbohydrates, fat, minerals, vitamin C and carotene, etc. It can sterilize and prevent infection, and can also prevent and fight cancer , with the improvement of people's living standards, people are now gradually beginning to pay attention to healthy eating. The cultivation method of broccoli is relatively simple, so large-scale cultivation has been carried out in greenhouses, etc., but the current cultivation method only focuses on increasing the output of broccoli. Low-cost planting often easily leads to the decline of broccoli nutrition. At the same time, in order to effectively control the pests and diseases in the growth process of broccoli, a large amount of resistant drugs are usually used during the cultivation process, which will not only pollute the environment, but also affect the quality of broccoli. not meeting health standards
