Embodiment 1
[0038] A kind of industrialized seedling raising method of sowing and becoming seedlings of jatropha, comprising the steps of:
[0039] (1) After harvesting and threshing, the seeds (Sichuan jatropha) were refrigerated and stored at 4°C ( Figure 1-4 );
[0040] (2) Before sowing, the seeds were washed with water and soaked overnight (about 10h), then soaked in the treatment solution for 15min, and then treated with 150mg / kg gibberellin GA 3 Soak for 8 hours; the treatment solution is H 2 SO 4 、GA 3 mixed aqueous solution, where H 2 SO 4 15% quality score, GA 3 The concentration is 150mg·kg -1 .
[0041] (3) Sowing in the middle and late February, first mix the seeds and river sand at a weight ratio of 1:2, and then evenly spread them on the seedling tray filled with a 2cm thick substrate, cover the Thick fine sand; spreading density per 1cm 2 seed.
[0042] The matrix is composed of peat soil: perlite (w / w) = 2:1, wherein the peat soil is special peat soil imp...

[0048] A kind of industrialized seedling raising method of sowing and becoming seedlings of jatropha, comprising the steps of:
[0049] (1) After harvesting and threshing, the seeds (Guizhou jatropha) were refrigerated and stored at 4°C;
[0050] (2) Before sowing, the seeds were washed with water and soaked overnight (about 10h), then soaked in the treatment solution for 15min, and then treated with 150mg / kg gibberellin GA 3 Soak for 8 hours; the treatment solution is H 2 SO 4 、GA 3 mixed aqueous solution, where H 2 SO4 15% quality score, GA 3 The concentration is 150mg·kg -1 .
[0051] (3) Sowing in mid-March, first mix the seeds and river sand at a weight ratio of 1:2, then evenly spread them on the seedling tray filled with a 2cm thick substrate, cover Thick fine sand; spreading density per 1cm 2 seed.
[0052] The matrix is composed of peat soil: perlite (w / w) = 10:1, wherein the peat soil is special peat soil imported from Klasmann, Germany, and the perlite...
Embodiment 3
[0058] To verify the effect of different seed treatments on germination:
[0059] Taking the seeds of Jacarina japonica stored in cold storage at 4°C as the research object, a completely randomized experimental design was adopted, and the seeds were washed with water and soaked overnight (about 10 hours), and then the seeds were soaked as follows:
[0060] (1) Seed soaking in distilled water for 15 minutes;
[0061] (2) H with a mass fraction of 5% 2 SO 4 Soak the seeds for 15 minutes;
[0062] (3) H with a mass fraction of 10% 2 SO 4 Soak the seeds for 15 minutes;
[0063] (4) H with a mass fraction of 15% 2 SO 4 Soak the seeds for 15 minutes;
[0064] (5) H with a mass fraction of 5% 2 SO 4 Soak the seeds for 15 minutes;
[0065] (6) 100mg / kg GA 3 Soak for 8 hours;
[0066] (7) 150mg / kg GA 3 Soak for 8 hours;
[0067] (8) 200mg / kg GA 3 Soak for 8 hours;
[0068] (9) 250mg / kg GA 3 Soak for 8 hours;
[0069] (10) 300mg / kgGA 3 Soak for 8 hours;
[0070] Eve...
