Introduction and cultivation method of high oil content jatropha curcas

Abstract

The utility model discloses an introduction and cultivation method of Jatropha curcas with high oil content, which comprises seed selecting and sterilization treatment, nutrition bags seedling, as well as transplanting, fix planting and other steps. The invention is on the basis of the optimal selection implemented to the seeds of origin. Through the physical and chemical treatment to the seeds, the germination rate of fine varieties seeds of Jatropha curcas with high oil content can be more than 97%. With the nutrition bags seedling technology, not only the premium germchits can be effectively provided based on the needs of germchit quantity and season, but also the technical support can be provided for the farmers and companies engaged in the Jatropha curcas planting. A relaible basis can also be established for the full utilization of land resources and the realization of scale planting. Meanwhile the site condition impacts to the yield formation and quality assurance of Jatropha curcas are fully considered, and the high-yielding, stable, high quality seeds with high oil content are cultivated. Through the detection to the fruits or seeds, the physicochemical property and the fatty acid composition are found to be in few discrepancies with those of the origin, and the good economic characters of the origin are basically maintained.

Description

technical field

[0001] The invention relates to the field of introduction and cultivation of woody energy plants, in particular to a technique for the introduction and cultivation of Jatropha curcas with high oil content. Background technique

[0002] Jatropha curcas L., a plant of the genus Jatropha in the family Euphorbiaceae, is a semi-succulent small tree or shrub. There are about 200 species in the world. They are distributed in tropical or subtropical regions. in tropical America and Africa. There are 4 species in my country, mainly distributed in Guangdong, Guangxi, Yunnan, Sichuan, Guizhou, Taiwan, Fujian, Hainan and other provinces. As a perennial woody oil tree species, the oil content of Jatropha curcas seed kernels is about 50%, the highest can reach 60%, and the oil content exceeds common herbaceous crops such as rape and soybean. It can be used as an ideal biodiesel raw material, thus becoming the world's A recognized bioenergy tree. Jatropha curcas is a mul...
