Problems solved by technology

Since most leafy vegetables are nitrate-loving plants, the maximum yield can only be achieved under nitrate nitrogen, coupled with the limitation of weak light environment in facility cultivation, it is more likely to cause nitrate accumulation

Embodiment Construction

[0023] The technical solutions of the present invention will be further described below through specific embodiments. The methods used in the examples are conventional methods unless otherwise specified, and the percentages are volume percentages unless otherwise specified.

[0024] 1. First of all, the non-heading cabbage is treated with LED light source in April slow, the steps are as follows:

[0025] (1) Preparation of seedlings: Soak non-heading Chinese cabbage seeds in clear water for 8 hours, and put them into sponge seedling-raising blocks soaked in clear water to grow seedlings. The environmental conditions are as follows: under natural light conditions, the temperature is 20±2°C, and the photoperiod is 12h. d -1 , the relative humidity is controlled at 80% to 90%; after the two true leaves of the seedlings are fully unfolded, the seedlings are moved into a hydroponic tank filled with Hoagland nutrient solution for hydroponic cultivation, and the hydroponic condition...

Abstract

The invention discloses a cultivation method for using an LED light source to quickly and effectively reduce the nitrate content in Brassicacampestris ssp.chinensis Makino. The method comprises the first step of preparation of seedlings, wherein Brassicacampestris ssp.chinensis Makino seeds are firstly put into clean water to be soaked, then the soaked seeds are put into a sponge seedling raising block which is soaked by water, and after two true leaves of the seedlings totally spread, the seedlings are transplanted into a water planting box to be subjected to water planting; the second step of LED light source treatment, wherein when the Brassicacampestris ssp.chinensis Makino grows to 8-16 true leaves, the Brassicacampestris ssp.chinensis Makino is subjected to treatment for 10-48 hours through continuous illumination under the LED light source, the temperature at day is 22-25 DEG C, the temperature at night is 18-20 DEG C, the light intensity is set to be 100-150 micromole.m<-2>s<-1>, and the relative humidity is controlled to be 60%-80%. According to the cultivation method for using the LED light source to quickly and effectively reduce the nitrate content in the Brassicacampestris ssp.chinensis Makino, the quality of the Brassicacampestris ssp.chinensis Makino is improved, the nitrate content can be quickly and effectively reduced within a short time, the safety quality is improved, the energy is saved, and the environmental protection is achieved.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a cultivation technique for rapidly and effectively reducing the nitrate content of non-heading Chinese cabbage by using an LED light source. Background technique [0002] Vegetables are an indispensable plant food in people's daily life. It provides humans with a variety of essential amino acids and rich vitamins, minerals and cellulose. At the same time, vegetables are also a crop with high nitrate content, which is the main source of nitrate absorbed by humans, especially stem and leaf vegetables. Since most leafy vegetables are nitrate-loving plants, the maximum yield can only be achieved under nitrate nitrogen, and coupled with the limitation of weak light environment in facility cultivation, it is more likely to cause nitrate accumulation. The nitrate content in food has always been a matter of great concern to people, especially vegetables, and the level of nitrate content is r...
