Embodiment 1

[0006] Embodiment 1: After the seeds were first soaked in clear water for 4.5 hours, soak 20,000 grains (about 17 grams) of Jatropha tomentosa seeds with 1 liter of 6% sodium bicarbonate solution for 3.5 hours, soak at 26°C ± 0.8°C in temperature, then add clear water to rub After rubbing and washing and destroying the waxy layer on the surface, soak it in water for 6.5 hours and sow it in the seedbed. After 40 days, 19895 seedlings with more than 2 true leaves were obtained, and the seedling rate was 99.5%. It can also be transplanted 19,789 seedlings with a height of 1.2 to 1.5 meters can be obtained after 8 months in a nursery using the organic compound fertilizer sold in the market as base fertilizer, and the total seedling rate is 98.9%.

Embodiment 2

[0007] Embodiment 2: Soak 10000 (about 8.6 grams) Jatropha tomentosa seeds with 0.5 liter of 14% sodium bicarbonate solution for 0.1 hour after soaking the seeds in clear water for 2.5 hours, after soaking at a temperature of 30 ± 1°C. Add clear water to rub and wash to destroy the waxy layer on its surface, then soak it in clear water for 10 hours, then sow it in the seedbed. After 40 days, 9887 seedlings with more than 2 true leaves were obtained, and the seedling rate was 98.8%. It can be transplanted to a nursery using the organic compound fertilizer sold in the market as base fertilizer to obtain 9851 seedlings with a height of 1.2 to 1.5 meters after 8 months, and the total seedling rate is 98.5%.

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 for 2-5 hours, then soaking in 5-15% sodium bicarbonate solution in 5 hours, adding clean water to knead and wash until wax coat on the surface of seed of Idesia polycarpa being broken, and then soaking the processed seed in clean water for 6-12 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 tomentosa. Background technique [0002] Idesia Polycarpa Var. Vestita Diels is a variety of Idesia Polycarpa Var. Vestita Diels, which is a deciduous tree. It has the advantages of fast growth, good water and soil function maintenance, large fruit yield, high oil content, good oil quality, and edible. The unsaturated fatty acid content of Jatropha jatropha oil is more than 82%, the content of linoleic acid is more than 68.6%, the content of vitamin E is more than 1‰, it does not contain poisonous jatropha oil, and the erucic acid is less than 0.3%. It can produce high-quality It is also a good raw material for extracting linoleic acid, vitamins, and preparing biodiesel and high-grade lubricating oil. It is a better economic and ecological forest. The tung tree in Maoyeshan is 10-15 meters high and has a large crown. It is a good barrier for low-level vegetation in ...
