Propagation Techniques of Stichopus japonicus Seed 1 Seed Germination Treatment
Seed dormancy of Stichopus japonicus belongs to complex morphological and physiological dormancy types. Seed embryos can germinate after two different stages: morphological post-ripening and physiological post-ripening, and sealed dry storage for a certain period of time is helpful to relieve seed dormancy. In order to release the dormancy of Stichopus japonicus seeds, two rounds of stratification treatment are needed to obtain the ideal germination accelerating effect.
1. 1 first stage lamination treatment
From June 10 in the year of seed collection to May 1, * * * treatment lasted for 7 months. The specific methods are as follows: soak the dried seeds of Stichopus japonicus in tap water for 4 d, disinfect them with 1% CuSO _ 4 for 3 h, mix them with 3 times of fine sand, put them in plastic boxes, cover the holes and ensure ventilation. First, the seeds were treated at 15 ~ 20℃ for 85 d, then at 10 ~ 15℃ for 35 d, and finally at 4℃ for 85 d. During the treatment, the seeds were turned 1 ~ 2 times a day, and a proper amount of water was sprayed for moisture preservation. The treated seeds were placed in the environment of 15 ~ 20℃ and germinated at the high temperature of 15 d, and the germinated seeds were observed every day and picked out for sowing. The seed germination rate is 2.3% ~ 13.4%.
1.2 second lamination treatment
In mid-May, the seeds that did not germinate after the first round of stratification were mixed with sand and put into flowerpots, buried outdoors in the shade, and taken out for sowing in mid-April of the following year. In the meantime, it is necessary to regularly check the humidity of mixed sand and replenish water in time. The germination rate of seeds can reach more than 20%.
Application of 1.3 GA in promoting seed germination
To improve the germination rate of seeds, 100? Soaking seeds with 10-6mg/mL GA3 for 24 h can increase the seed germination rate by more than 1 times.
2 prevention and treatment of seedling damping-off disease
The results of many years' cultivation show that Stichopus japonicus seedlings are prone to damping-off, and the incidence rate is extremely high. If it is not properly controlled, it will lead to seedling decline.
2. 1 soil selection and disinfection
Sowing soil should be humus soil under broad-leaved forest on the mountain, and nutrient soil should be prepared according to 2 parts humus soil+1 part fine sand, which can be disinfected by autoclave to achieve the purpose of insecticidal sterilization. Even if the soil where Stichopus japonicus has been cultured is disinfected, the incidence rate is still high, so it is best not to reuse it.
2.2 Careful use of fungicides
The results showed that the use of fungicides such as carbendazim and zineb could effectively prevent the occurrence of sheath blight, but the seedlings of Stichopus japonicus were very sensitive to fungicides, which would lead to the stagnation of root growth and poor seedling growth. Be careful when using fungicides to control damping-off disease.
3 light adjustment
Stichopus japonicus is a negative plant in Northeast China. When the illumination exceeds 50000 lx, the leaves will burn, so it is necessary to adjust the illumination.
3. 1 light adjustment of seeding in the current year
Shading can be done after emergence in the year of sowing, and the light can be adjusted with a shading net with a light transmittance of 30%; It is necessary to remove the sunshade net on cloudy days to enhance the light intensity. Sowing seedlings in that year needed a small amount of light, but needed a proper amount of direct light. The growth conditions of seedlings under scattered light are poor.
3.2 light regulation of plants over 2 years old
For plants over 2 years old, the light can be adjusted with a shading net with a light transmittance of 30%, or the seedlings can be placed in a greenhouse with only scattered light, which has no obvious effect on their growth.
4 seedlings overwinter
Stichopus japonicus cultivated in greenhouse must overwinter outdoors. Although the plants that overwinter indoors can survive in the next spring, their growth rate is extremely slow. The specific methods are as follows: the container seedlings in the greenhouse are moved to the outdoor forest or under the shade shed at the beginning of September every year, and all the leaves are defoliated at 5438+1early October in June; Before the soil freezes in early June (5438+065438+ 10), dig a hole with a depth of 50 cm in the leeward, put all container seedlings in into the pit and cover them with straw. In the middle of June, when it snowed, in May 438+065438+10, the container seedlings of Stichopus japonicus in the pit were filled with snow and covered with soil again. After the topsoil was thawed in early March of the following year, it was dug out and moved to the greenhouse. After 10 d, it began to germinate and release leaves, and the survival rate was 100%.
