Embodiment Construction

[0029] The present invention will be further described below in conjunction with embodiment.

[0030] Jatropha cutting seedling raising method of the present invention comprises the steps:

[0031] The first step is to cut cuttings suitable for the cutting biological age stage from the female parent plant of Jatropha japonica, cut both ends of the cuttings to obtain cuttings, keep the ambient temperature of the cuttings at a suitable temperature, and the humidity of the incision at the trimmed end of the cuttings to be a suitable humidity. The above-mentioned suitable temperature is usually 16°C-30°C, and the suitable humidity is usually 60%-80%. The suitable incision bevel angle for the upper end of the cuttings is 60°-70°, and the suitable incision bevel angle for the lower end is 40°-50°.

[0032] The second step is to cover the cuttings in a timely manner: prepare 500-1000 times (for example, 600 times, 700 times, 800 times, and 900 times) of film-coating agent dilution w...

Abstract

The invention discloses a method for raising seedlings of jatropha curcas by cutting. The method includes the following steps: scissoring cuttings, keeping the cuttings at appropriate temperature, and keeping cut positions of the cuttings at appropriate humidity; coating the cuttings with a film in time; inserting the cuttings into a seedbed; subjecting the cuttings to moisture spraying and disinfection, keeping the humidity between 75% and 95%, spraying 1:600-1000 water solution of bactericide onto the cuttings once every 6 to 8 days, and stopping spraying after the cuttings root; performing fertilizer and water management of the cuttings, to be specific, spraying liquid manure 0.2%-0.5% in concentration once every 15-30 days after the cuttings root, wherein fertilization and moisture spraying are performed at different time; transplanting seedlings after emergence of the seedlings. The method has the advantages of investment saving, high survival rate, fast rooting, fast seedling emergence, no season limit, high seedling raising coefficient, low production cost, high production efficiency, low implementation threshold, no need of professionals and easiness in large-area popularization.

Description

technical field [0001] The invention relates to a method for raising jatropha seedlings by cutting. Background technique [0002] At present, Jatropha seeds are commonly used for seedling breeding. Jatropha jatropha seedlings are sexually propagated, so there is a large genetic variability of varieties, it is very difficult to breed good varieties, the yield is very low, the quality is not guaranteed, and there is no artificial controllability in the expectation of fruit bearing and high yield. [0003] In order to overcome the defect of Jatropha seed seedling cultivation, people adopt cutting propagation method to carry out Jatropha seedling cultivation, to overcome the above-mentioned defect of Jatropha seedling. But, because the Jatropha plant is a semi-succulent Euphorbiaceae woody plant, its roots, stems, branches, leaves, and buds all contain a large amount of protein-type latex, and the bacteria breed very quickly, so that the in vitro propagation materials of Jatrop...
