Embodiment 1

[0007] Embodiment 1: After washing 3000 Jatropha tomentosa fresh seeds with special detergent for fruits and vegetables, enter the germination bed to germinate. The thickness of the plastic foam in the lower part of the germination bed is 1 cm, and the thickness of the seed layer is 0.2 cm. During the germination period, the temperature of the germination bed is controlled at 5°C to 15°C. After 33 days, most of the seeds germinate, and they are sown in the seedbed. After 40 days, 4 pieces of true There were 2,958 seedlings above the leaves, with a seedling rate of 98.6%. After transplanting to the nursery for 7 months, 2,916 seedlings with a height of 1.2 to 1.5 meters were obtained, with an overall seedling rate of 97.2%.

Embodiment 2

[0008] Embodiment 2: After washing 50,000 Jatropha tomentosa fresh seeds with special detergent for fruits and vegetables, enter the germination bed to germinate. The thickness of the river sand in the lower part of the germination bed is 5 cm, and the thickness of the seed layer is 2 cm. During the germination period, the temperature of the germination bed is controlled at 15°C to 25°C. After 21 days, most of the seeds germinate, and they are sown in the seedbed. After 40 days, 4 true leaves are obtained The above 49,450 seedlings have a seedling rate of 98.9%. After transplanting to the nursery for 7 months, 48,850 seedlings with a height of 1.2 to 1.5 meters were obtained, and the total seedling rate was 97.7%.

Abstract

The invention discloses a seed germination method for idesia polycarpa seedling culture, which comprises the steps of cleaning oil stains on the surfaces of fresh seeds by use of a special detergent for fruits and vegetables; germinating the cleaned seeds in a germination bed.

Description

technical field [0001] The invention relates to a seed germination method for cultivating Jatropha tomentosa seedlings. Background technique [0002] Idesia Polycarpa Var. Vestita Diels (Idesia Polycarpa Var. Vestita Diels) is a variant of the genus Vestita Diels, a deciduous tree. The unsaturated fatty acid content of Jatropha jatropha oil is more than 80%, the linoleic acid content is more than 70%, the vitamin E content is more than 1‰, and it does not contain toxic and harmful ingredients. It is not only a high-quality edible oil, but also the extraction of linoleic acid and vitamin E. Excellent raw material for biodiesel and high-grade lubricating oil. The rich production period of Jatropha Maoye lasts for more than 40 years, and the yield per plant can reach 200kg (dried fruit), and the oil content of dried fruit is 38-42%. The root system of Jatropha magnolia is well developed, and the function of water and soil conservation is strong. The trunk of Tongzi Maoye is ...
