Embodiment 1

[0013] Embodiment 1: carry out according to the following steps

[0014] 1. Preparation of Jatropha curcas seedlings: take seeds and reproduce them for 12 months without pests and diseases.

[0015] 2, mycorrhizal agent preparation: with white-flowered clover (Trifolium repens) as host, Glomus (Glomus) and giant cystomyces (Gigaspora) fungus (purchased from Beijing Sensenyuan Biotechnology Co., Ltd. Endophytic mycorrhizal fungus), peat, plant ash or river sand 60-90%, disinfection powder 0.5-2%, phosphate rock powder 6-8%, after mixing evenly, build a heap for 12-20 days, then mix in 1- 1.5% arbuscular mycorrhizal fungi (Arbuscular mycorrhizalfungi) was used as the strain, and then sowed the sterilized clover seeds, and continued to cultivate at 25-28° C. for 8-10 weeks to obtain the mycorrhizal agent.

[0016] 3. Mechanical treatment and disinfection of the roots of the seedlings: Cut off the fibrous roots of the Jatropha curcas seedlings, and perform artificial mechanical d...

Abstract

The invention discloses a leprosy tree bacteria root nursery sock growing method, comprising the procedures of bacteria root agent preparation, seedling process, bacteria root agent inoculation, replanting and vaccination of seedling tubes. The invention is vaccinated with mycorrhizal fungi, which improves stress resistance and adaptability of leprosy trees. And the bacteriorhiza agent vaccination method has the advantages of little energy consumption, convenient employment, excellent production increase and extensive application scope, promotes the growing of leprosy trees and provides large numbers of high grade root bacteria seedlings for industrialized plantation of leprosy trees.

Description

1. Technical field [0001] The invention relates to a method for growing seedlings of Jatropha curcas mycorrhizae, which belongs to the field of modern agricultural technology. . 2. Background technology [0002] Jatropha carcas L. is a drought-tolerant and barren-tolerant multipurpose tree species widely distributed in tropical or subtropical regions. my country is mainly distributed in the vast dry and hot valleys and tropical regions south of the Yangtze River, with the most in Yunnan, followed by Sichuan. Planting Jatropha curcas can not only improve the ecological environment, but also have a wide range of applications in medicine, chemical industry, protein feed, etc. with its seeds and sap, especially in the application of "biodiesel", which has become more and more popular internationally. widespread concern in society. Mycorrhiza is a very common ecological phenomenon in nature. It is a symbiotic combination of fungi and roots formed by the combination of roots of...
