Embodiment 1

[0022] Sowing and germination: Choose JL003-rubbergrass seeds with full seeds, soak them in 30°C water for 8 hours, and then put them in a 30°C incubator for germination. 1 seed,

[0023] After sowing, the seedling management period is carried out, the EC value of the nutrient solution is 1.0-1.1mS / cm, and the pH value is 6.0-7.0, until 5-6 true leaves are cultivated.

[0024] Cultivation period management: When the rubber grass seedlings grow to 5-6 leaves and 1 heart, the rubber grass seedlings are planted on the hydroponic module cultivation plate, the planting density is 30 plants / ㎡, and the root system is kept at least 70% immersed. In the nutrient solution, the EC value of the nutrient solution is 1.8-2.mS / cm, the pH value is 6.0-7.0, the temperature of the nutrient solution is 18-20 ℃, the ambient temperature conditions are 23 ℃ in the light period, 18 ℃ in the dark period, air Humidity 70-80%, CO 2 The concentration is 1000 ppm. The light source is set with 7 kinds ...

Abstract

The invention relates to the technical field of plant factory planting, in particular to a light environment regulation and control method for regulating and controlling root system growth and development of kok-saghyz, which is characterized in that a light environment is provided for seedling raising and cultivation through an LED lamp, the light quantum proportion range of red light of 600-699 nm and blue light of 400-499 nm is controlled to be 3.32-5.21, and the proportion range of the sum of light quantum of far red light of 700-780 nm and light quantum of green light of 500-599 nm is 13-18% when the sum of light quantum of far red light of 700-780 nm and light quantum of green light of 500-599 nm is 380-780 nm. The kok-saghyz plant factory cultivation is carried out through the full-artificial light, annual production can be achieved, and meanwhile root system expansion of the kok-saghyz can be promoted.

Description

technical field [0001] The invention relates to the technical field of planting in plant factories, in particular to a light environment regulation method for regulating the growth and development of rubber grass roots. Background technique [0002] Natural rubber is an important strategic material and industrial raw material. Rubber grass, also known as Russian dandelion, is a perennial herb of the genus Asteraceae. Its roots contain latex, and the root system contains more than 20% rubber. Rubber can be extracted and used in the manufacture of general rubber products. Guayule is also known as the world's three major rubber-producing plants, and is one of the important rubber-producing crops that has attracted much attention in recent years. [0003] At present, rubber grass is mainly cultivated in the open field, which is easily restricted by the natural environment and cannot achieve annual cultivation and production. At present, there is no report of indoor rubber grass...
