Problems solved by technology

[0006] However, in the actual planting process, it is difficult for the caddis to form seeds and to reproduce asexually with underground tubers
Similar to potatoes, after the virus infects the caddis worm, it can be passed on from generation to generation and spread through the reproductive organs, resulting in the degradation of the caddis worm's reproductive properties, and the decline in yield and quality

Embodiment 1

[0018] Effect of embodiment 1 photoperiod on the growth process of caddis silkworm

[0019] 1 Effects of sunshine duration on the flower bud differentiation of Cadida chrysalis

[0020] Cadida tubers were collected from Liangping Datian colony in Chongqing; two separate photoperiod treatment areas, A and B, were built around the net room with light-shielding materials to block interfering light sources. Area A is the control, with natural sunlight, and the daily light duration is about 8-11 hours; in addition to natural sunlight, area B is supplemented with 2000Lx artificial light sources, and supplemented with 7 hours of sunshine between 15:00 and 24:00 every day, so that the sunshine duration exceeds 14 hours .

[0021] Simultaneously (February 1st) sow seedlings in A and B districts respectively. Before the emergence of first-order branches (on March 20), the caddis seedlings were removed from the main branches and transplanted into potted plants. Fill each pot with 10kg...

Embodiment 2

[0045] The influence of embodiment 2 different methods of chrysalis seedlings on the genetic characteristics of plants

[0046] Collect and adopt the method optimized in embodiment 1 to realize the sexual reproduction of 12 caddis silkworm plant populations (35 caddis silkworm plants in each group), be divided into four groups, and the light intensity of each group is respectively 1000Lx, 1500Lx, 2000Lx and 2500Lx, each group was randomly collected seeds from the corresponding communities under three treatments of 9h light, 10h light and 11h light, and each treatment was planted 30m 2 In the plot, the ambient temperature is controlled at 25±2°C (the temperature condition is controlled by the altitude), and the yield per mu of caddis silkworm is measured after harvest. Comprehensive scoring evaluation criteria:

Abstract

The invention provides a sexual propagation method based on stachys sieboldii photoperiod characteristics for solving the problem that stachys sieboldii is hard to form seed to carry out sexual propagation. The method includes steps of placing a plant in an environment with dark time of 13-16 hours and light time of 8-11 hours every day before the stachys sieboldii is branched for the second time, wherein the illumination intensity is 2000-5000 Lx; inducing the stachys sieboldii to bloom and perform the sexual propagation. The invention solves the technical problem that the stachys sieboldii is hard to carry out sexual propagation; through the sexual propagation, the stachys sieboldii variety is optimized.

Description

technical field [0001] The invention relates to a method for preserving germplasm materials of the caddis silkworm, in particular to a method for sexual reproduction based on the photoperiod characteristics of the caddis silkworm. [0002] technical background [0003] Grass silkworm, which looks like silkworm or silkworm chrysalis, is quite peculiar. It is also known as pagoda vegetable, dikuniu, ground silkworm, silver bar, arhat vegetable, manna seed, soil chrysalis, and soil caterpillar fungus. It got its name, and it is commonly known as diliuer in northern Shaanxi. The tubers contain a lot of starch and sugar, and are a new vegetable that people love. Grassworm is a perennial herbaceous plant of the genus Stachys in the family Lamiaceae. It is erect and has a rhizome with dense fibrous roots. At the top of the stem, there is a bunch of spherical hypertrophic screw-shaped tubers, that is, the edible part. The rhizomes of chrysalis are mostly spindle-shaped, and some are...
