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

Embodiment 1

[0038] For 3 consecutive years, several Jatropha wild or artificially cultivated varieties with strong appearance, many branches, high yield, high quality and high oil content were selected from Guangxi, Yunnan, Guizhou, Sichuan and other places as the breeding target. Cutting method, after the seedlings are transplanted and survived, cut them off at a distance of 30-50 cm from the ground, spray a compound amino acid salt growth regulator once, and when the first branch reaches 20-25 cm, cut it 2-5 cm below the top growth point Cut it off to make it branch again, and then spray the compound amino acid salt growth regulator again, and repeat this 2-3 times, so that the number of branches reaches more than 30-50 branches per plant. When the plant blooms and bears fruit, choose Individual plants that show vigorous growth, mainly record plant height, branch length, number of branches, number of flowering, number of fruits, oil content, etc. Individual plants that perform well in al...

Embodiment 2

[0040] The "Preferred No. 3" selected in the previous year was planted into the corresponding strain, and the planting and selection methods were the same as above. In order to improve the genetic stability of the population and expand the population size of the strains, the strains were propagated for another year before entering the strains for propagation. Finally, the superior strain and the variety used in production are obtained as a comparison, and the strain comparison test is carried out, and then enters the prescribed procedure for new variety approval in the later stage, and is planted and bred into a new variety.

Embodiment 3

[0042] After several years of breeding by the inventor, the early-maturing and high-yielding Jatropha varieties have been selected, and the oil content of the seeds is 58.2%-64.4%. Fertilizer, flower bud differentiation, budding, spraying compound amino acid salt regulator at the beginning of flowering, under excellent and scientific management and protection conditions, it can bloom and bear fruit once every 25-30 days, and it can bloom and bear fruit 5-6 times within a year.

[0043] The compound amino acid salt growth regulator is a foliar plant growth retarder such as chlormequat and B9 and a compound amino acid salt prepared by the inventor himself. The compound amino acid salt accounts for 90% of the total dry weight, and the growth regulator accounts for 10%. The compound amino acid is prepared from the hydrolyzate extracted from animal hair, and the production method is as follows: animal hair, including human hair, pig hair, waste wool, rabbit hair, chicken feather, d...

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...
