Embodiment 1

[0008] Embodiment 1: 10,000 grains (approximately 8.5 grams) of S. tomentosa seeds were first soaked in clear water for 3.5 hours, then soaked with 3.1% KH 2 PO 4 Soak 1 liter of the solution for 6 hours, wash with water and rub to the degree of the waxy layer on the surface of the damaged seeds. After soaking in water for 4 hours, the seeds are ready for use. The treated seeds were evenly sown into the seedbed. After 60 days, there were 9875 seedlings with 2 true leaves, and the seedling rate was 98.7%. After 10 months after transplanting to a nursery using commercially available compound fertilizer as base fertilizer, 1.2 to 1.5 meters of seedlings could be obtained. There are 9697 trees, and the seedling rate is 96.9%.

Embodiment 2

[0009] Embodiment 2: 5000 grains (about 4.1 grams) of Jatropha tomentosa seeds were first soaked in clear water for 1 hour, then soaked with 7% KH 2 PO 4 Soak the seeds in 0.5 liter of solution for 1.5 hours, add water and rub to destroy the waxy layer on the surface of the seeds, and then soak in water for 8 hours. The treated seeds are evenly sown in the seedbed, and after 2 months, 4921 seedlings with more than 2 true leaves are obtained, and the seedling rate is 98.4%. Transplanted to a nursery using commercially available compound fertilizers as base fertilizer, 1.2 to 100 seedlings are obtained after ten months. There are 4831 saplings with a height of 1.5m, and the seedling rate is 96.6%.

Abstract

The invention relates to a pretreating method for seed of Idesia polycarpa seedling, comprising the steps of soaking the seed of Idesia polycarpa in clean water, soaking in 3-7% KH2PO4 solution in 7.5 hours at the temperature more than 25-32 DEG C, adding clean water to knead and wash after soaking, and then soaking the processed seed in clean water for 4-8 hours, sowing the seed in seedbed to cultivate, at last transplanting the seedling in seedling nursery with base fertilizer to cultivate.

Description

technical field [0001] The invention relates to a seed pretreatment method for raising seedlings of Jatropha jatropha. Background technique [0002] Idesia Polycarpa Var. Vestita Diels is a variant of Idesia Polycarpa Var. Vestita Diels. It is a deciduous tree with a height of 10-15 meters. It is a high-quality woody edible oil plant, the content of unsaturated fatty acid in its oil is more than 82%, the content of linoleic acid is more than 68.6%, the content of vitamin E is more than 1‰, and it has no poisonous and harmful ingredients. The oil content of the fruit is more than 38%, which can produce high-quality edible oil, extract linoleic acid and vitamins, and is also a good raw material for preparing biodiesel and high-grade lubricating oil; its root dense layer is 20-60cm below the surface and forms a network shape, the prolific period is more than 50 years, and the fruit yield per mu can reach more than 1500kg. The root system of Jatropha magnolia is well developed...
