Method for high yield, prematurity and dwarfing cultivation of jatropha curcas

Abstract

The invention discloses a biodiesel raw tree, in particular to a method for high yield, prematurity and dwarfing cultivation of jatropha curcas. Plants with excellent biological and economical properties are selected out of numerous wild jatropha curcas or cultivated excellent variant strains; furthermore, by preferential selection, individual system breeding and artificial cultivation, domestication and breeding for many years, the plants are cultivated to excellent tree species; subsequently, by adopting adaptive tests for many years and multi-technologies, the jatropha curcas bears fruits in the transplanting year and can bear fruits more than five times per year; the oil content of the kernel of the jatropha curcas is 58.2-64.4%, the dry seeds per plant is 2-3kg, the yield per Mu in the transplanting year is 200-300kg (equivalent to the output of general wild adult tree after 3-4 years), and the yield per Mu can achieve 600-1000kg after growing up.

Description

technical field [0001] The invention relates to a method for cultivating biodiesel raw material trees, in particular to a method for cultivating jatropha with high yield, early maturity and dwarfing. Background technique [0002] Jatropha curcas L. is often called Jatropha curcas L., also known as hibiscus tree, tung tree, bright tung tree, and stinky tung tree. It is a deciduous shrub or small tree in the family Euphorbiaceae. Among the more than ten kinds of plants currently used to extract biodiesel, the most promising biodiesel energy plant is recognized as a biodiesel tree by the world. [0003] Jatropha wild species are widely distributed in tropical and subtropical regions of the world, such as South America, Africa, India, Indonesia, Laos, Cambodia, Sichuan, Guizhou, Yunnan, Hainan, and Guangxi in my country. The root system of Jatropha Jatropha is strong and developed, and has a strong ability to withstand drought and barrenness. Because the branches, trunks, and r...

Problems solved by technology

[0004] However, the Jatropha species introduced and cultivated by people are relatively chaotic at present, and the yield is uneven. Under the natural state, it takes 3-4 years to bear fruit, only 1-2 times a year, and each branch bears 3-7. more than ten at most

And in the case of forest conventional management and cultivation, there are few branches and low yield. There are only 1-5 branches in the first year of planting, 5-10 branches in the second year, and only 10-20 branches in the 3-4 year. One branch, high tree vigor, it is observed that most of Jatropha jatropha bloom and bear fruit at the top of the branches, with few branches and few fruits, which increases the difficulty of fruit picking. In the natural state, the yield is low, and the yield per plant of 3-4 adult trees is 1-3 kg , 100-330 kg per mu
