Method for planting Chinese cabbage in planting factory

Abstract

The invention belongs to the agriculture planting field and relates to a method for planting Chinese cabbage in a planting factory, light emitted by an LED lamp with the proportion of red-blue light being 60%-99% is used for irradiating the Chinese cabbage, the planting method sequentially comprises the following steps of a sowing and germination acceleration stage, a seedling stage, a seedling slowing stage, a rosette stage, an early pacing stage, a middle pacing stage, a later pacing stage and a harvesting stage, illumination is performed alternatively during the seedling stage, the seedlingslowing stage, the rosette stage, the early pacing stage, the middle pacing stage, the later pacing stage and the harvesting stage, and in the harvesting stage, continuous illumination is performed one day before harvesting. The method for planting the Chinese cabbage in the planting factory has the advantages that the planting cost is low, and the maturing time is quick.

Description

technical field [0001] The invention belongs to the field of agricultural planting and relates to a planting method of Chinese cabbage. Background technique [0002] The plant factory is an efficient agricultural system that realizes annual continuous production of crops through high-precision environmental control in the facility. It uses computers to control the temperature, humidity, light, CO 2 The concentration and nutrient solution and other environmental conditions are automatically controlled, so that the plant growth in the facility is not or rarely restricted by natural conditions. Labor-saving production. The plant factory has a high multiple cropping index, can produce all year round, and avoids continuous cropping obstacles. Leafy vegetables are not easy to store, but annual production is required to meet market demand, so plant factories are especially suitable for cultivating leafy vegetables. [0003] In the plant factory, the hydroponic agricultural produc...

Problems solved by technology

[0005] To sum up, the current disadvantages of cabbage planted in plant factories are: 1. High energy consumption and high planting cost; 2. The nutrient solution, light source, temperature and other facilities used in each growth stage of cabbage have the same environment, and the growth cycle 3. The quality of cabbage is low, and nutrient solution is needed during the planting process, so that the nitrite content in mature cabbage is 4.5-5.5mg / kg, which is close to or even higher than the standard of pollution-free vegetables The content of nitrite, cabbage is a calcium-loving plant, in the case of calcium deficiency, it is prone to "dry heartburn", generally between 8-10%
