Abstract

The invention discloses a seed treatment method for raising seedlings of Idesia polycarpa. The method comprises the following steps: mixing seeds with fluvial sand and adding water to the obtained mixture; autogenously grinding the mixture added with water in an autogenous mill after 8-48h; cleaning the autogenously ground mixture, or kneading and cleaning the mixture added with water after 8-48h; and raising the seedlings with the treated seeds on a seedbed.

Description

technical field [0001] The invention relates to a seed treatment 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. 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 is more than 40 years, and the yield per plant in the rich period 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 straight...
