Embodiment 1

[0033] Tong one kind of lotus seed germination and seedling methods, wherein the specific process is as follows:

[0034] Seeds Pretreatment S1: lotus Tong trees collected from mature, full, no pest fruit, soaking 5 ‰ seawater salt concentration, 1: 400 dilution ratio applied carbendazim fold, put in the shade conditions (illuminance 5000 ~ 6000lux, 25-28 ℃, natural ventilation) decay accelerating seed coat; seed soaking process, soaking solution replaced once every two days, and gently flip seeds per day, to promote aerobic respiration seeds, thereby accelerating seed germination ; 10 days after the seeds removed, stripped testa, rinsed with water for 30 minutes, and then for the sowing; condition wherein the shading layer is 2 for sun shade net pin 3;

[0035] Sowing S2: mixing matrix seedbed 1 / 3 and 2 / 3 sand consists of clay, sealed disinfection with potassium permanganate (0.05%) before sowing, open to take a day after sowing, sowing methods employed for Bunch, pot seed planti...

Embodiment 2

[0041] Example 2 Screening embodiment seeded matrix

[0042] A method Tong lotus seed germination and seedling method, the specific embodiment of the process steps as in Example 1 S1 and S2, seeding the matrix has been studied using S2, wherein the step, since the longer sides of Lin Ye Tongsheng beach, so conventional breeding methods, commonly used as sand for seedling nursery substrate, but the effect is not satisfactory, and therefore the present embodiment, in testing different nursery substrate.

[0043] Were divided into five groups, were used in which the substrate 1: sand, 2: 1 / 3 + 2 / 3 sand clay, 3: 1 / 2 + 1 / 2 sand clay, 4: 2 / 3 Clay + 1 / 3 sand, 5: clay.

[0044]Each experimental group 3 replicates, repeated a pot, 60 seeds per pot

[0045] Germination: sealed disinfection with potassium permanganate (0.05%) before sowing, open to take a day after sowing, sowing methods employed for Bunch, one seed per hole, casing 0.5-1cm. Day after sowing with a water shower 5 ‰ salt conc...

Embodiment 3

[0048] Example 3 Screening seedling substrate embodiment

[0049] A method Tong lotus seed germination and seedling method, a specific procedure as in Example 1, to explore the impact of substrates for seedling survival of seedlings, of the matrix used in step S3 seedling was investigated.

[0050] Experimental setting process: 1: 1 / 2 + 1 / 2 sand clay; 2: Clay 1 / 3 + 1 / 3 + 1 / 3 sand coconut husk; 3: 1 / 4 +1 / 4 clay sand +1 / 2 coconut husk; 4: full sand.

[0051] Each processing transplanting shoots 30, each treatment was repeated three times, until the seedlings grow from 8 to 10 true leaves, lines up 70 ~ 80cm, pest-free seedlings. Statistical data for each treatment were averaged.

[0052] Cotyledons be unearthed, when the shoots reached 8-10cm height, the seedlings is moved to the seedling substrate after sterilization, disinfection methods with seedbed substrate; with a salt concentration of 4 ~ 6 ‰ shower water every day after transplant seedlings, so that the substrate holder in...

Abstract

The invention discloses a seed germination method and a seedling raising method of the tung tree. The method of seed germination is first soaking the seeds in seawater, then soaking them under shading and ventilation conditions; then sowing them in a specific substrate, and regularly showering them with seawater and fresh water. The method for seed germination of the present invention, by first soaking the seed in salt water, and then soaking with soaking liquid under the condition of shading and ventilation, the germination rate of the seed is increased to 67-68%. The method is not only simple, but compared with the existing method, the germination rate of the seeds has been significantly improved, which is about 2 times that of the prior art; at the same time, the survival rate of the seedlings obtained by it is high, and after the substrate After the screening and shading treatment, the survival rate of the seedlings has also been significantly improved, which is more than 95%. Protection and greening of the beach environment.

Description

Technical field [0001] The present invention relates to the field of plant breeding, more particularly, to a method and a method for breeding Tong lotus seed germination. Background technique [0002] Endangered mangrove lotus Tong (Hernandia nymphaeifolia (c.Presl) Kubitzki), under the hernandiaceae (Hernandiaceae), hernandia (Hernandia L.). Which is distributed in tropical Asia, often growing on the beach, located in Hainan Island in China's east coast and southern Taiwan. According to reports and field investigation, the number of wild lotus Tong Hainan Island, less than 300. In Qionghai, lotus Tong Chang and Casuarina together, to the forefront of sandy coastal shelterbelt of trees Coast. But now, only a handful of several strains of lotus Tong Qionghai area can normally bear fruit, more than the rest of the lotus Tong showed no flowers or fruit without flowering phenomenon. 2014 The project group reported pre-tung lotus seed germination rate is not high (<40%). The result...
