Problems solved by technology

The traditional Pseudostellaria Pseudostellaria planting is mainly propagated by root tubers in the field. Because the production areas use root tubers for propagation all the year round, the variety degenerates and the disease is serious. In some areas, the infection rate of viral diseases is as high as 90%, and the yield is reduced by more than 50%.

Embodiment 1

[0044] A method for raising seedlings of heterophylla heterophylla in a plant factory, comprising the steps of:

[0045] 1. Stratification: Mix fresh, mature and plump Pseudostellariae Pseudostellaria seeds evenly into moist perlite, and stratify them in a refrigerator at 0°C for 40-80 days.

[0046] 2. Sowing: Transplant the germinated Pseudostellariae Pseudostellaria seeds into seedling trays, and cultivate them under LED light source for 30 days.

[0047] 3. Cultivation: Put the sown Pseudostellariae Radix in red and blue light with a ratio of 6:1 and light intensity of 200μmo·m -2 ·s -1 , with a photoperiod of 16 hours and a room temperature of 25°C on a three-dimensional cultivation rack in a plant factory, cultivated for 30 days to obtain Pseudostellaria radiata seedlings, wherein the wavelength of red light was 660nm, and the wavelength of blue light was 450nm. During the cultivation process, 1 Secondary nutrient solution, 600ml each time, the formula of the nutrient ...

Embodiment 2

[0049] The operation process of this embodiment is the same as that of Embodiment 1, the difference is that during cultivation, the transplanted Pseudostellariae Radix Radix Radix Radix Radix Radix Radix Radix Radix Radix Radix Radix Radix or Radix Radix or Radix Radix Radix or Radix Radix Radix is ​​placed in red and blue light with a ratio of 8:1.

Embodiment 3

[0051] The operation process of this embodiment is the same as that of Embodiment 1, the difference is that during cultivation, the transplanted Pseudostellariae Radix Pseudostellariae seedlings are exposed to red and blue light with a ratio of 10:1.

Abstract

The invention discloses a seedling raising method of Pseudostellaria heterophylla in a plant factory, which comprises the following steps: step 1, performing low-temperature stratification on Pseudostellaria heterophylla seeds or seed Pseudostellaria heterophylla at 0-15 DEG C for 40-80 days; and step 2, performing illumination culture on the Pseudostellaria heterophylla seeds or seed Pseudostellaria heterophylla subjected to low-temperature stratification in red and blue light for about 30 days to obtain Pseudostellaria heterophylla seedlings, wherein the ratio of the red light to the blue light is (6-10): 1, the illumination intensity is 180-220 [mu] mo.m <-2 >. S <-1 >, and the photoperiod is 12-24 h. The seedling raising method for the Pseudostellaria heterophylla in the plant factory can greatly short en the time for obtaining the Pseudostellaria heterophylla seedlings , is easy to operate, facilitates manual operation, and has high practical application value for Pseudostellaria heterophylla seed seedling raising, seed Pseudostellaria heterophylla breeding and large-scale planting.

Description

technical field [0001] The invention belongs to the technical field of artificial planting of heterophylla, and relates to a method for raising seedlings of heterophylla in a plant factory. Background technique [0002] The plant factory is a high-efficiency plant production system with intelligent control of environmental conditions such as artificial light. It can achieve stable and efficient seedlings throughout the year. It is the most advanced seedling method and the development direction of the seedling industry. At present, seedling plant factories have begun to be applied to crops with high economic conditions such as tomatoes, cucumbers and other vegetables, seedlings, flowers and medicinal plants. [0003] Pseudostellaria heterophylla (Miq.) Pax is the dried root of Pseudostellaria heterophylla (Miq.) Pax. It is rich in polysaccharides, cyclic peptides, proteins, amino acids and other functional components, which can lower blood sugar and blood lipids, regulate im...
