A kind of compound regulator for promoting root growth of Chinese fir cuttings and seedling cultivation and preparation method thereof

Abstract

The invention relates to the technical field of agriculture cutting seedling, in particular to a cephalotaxus fortune cutting seedling rooting-promoting compound conditioner and preparation method thereof. The cephalotaxus fortune cutting seedling rooting-promoting compound conditioner is composed of the following components in weight: 600-850 mg of rooting conditioner, 10-30 mg of rooting additive, 10-25 mg of nutrient, 2-5 g of bactericide, and the balance of water and ethanol. The preparation method comprises the following steps: dissolving the rooting conditioner and the rooting additive into an I solution by using 95% ethanol, dissolving the nutrient and the bactericide into an II solution by using water; mixing I and II, adding water till a metered volume of 1000mL, uniformly stirring to obtained a finished solution for later use; through reasonable proportion of raw material components, effectively activating cambial cells to form callus at a cutting notch within short time, inducing the morphogenesis of adventives root, and improving the cutting rooting percentage and the cottage survival rate, wherein the average rooting rate of the twig cutting seedling achieves 99%, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural cutting and seedling cultivation, in particular to a compound regulator for promoting root growth and root growth of Chinese fir cutting and seedling cultivation and a preparation method thereof. Background technique [0002] Cephalotaxus fortunei Hook·f belongs to Cephalotaxus fortunei Hook·f, which belongs to Cephalotaxus fortunei Hook·f, and is a unique species in my country; Daozhen Autonomous County, Guizhou Province is the original place of my country Cephalotaxus fortunei Hook·f, and it is also the center distribution place of Cephalotaxus fortunei Hook in the world. The ester alkaloids contained in the harringtonine plants have anti-cancer activity, especially harringtonine and homoharringtonine have significant curative effects on leukemia, melanoma, lung cancer, breast cancer, and brain tumors. However, while developing and utilizing the cloverwood, the natural resources of the clov...

Problems solved by technology

[0003] In the prior art, sexual reproduction and asexual reproduction are adopted for industrialized and large-scale production of cloverleaf plants. However, for the sexual reproduction of cloverleaf plants, the speed of reproduction is relatively slow, and the seeds Therefore, in actual production, most of them adopt asexual reproduction, that is, use the stems of the genus Cedarwood for cutting seedlings and tissue culture. process

For tissue culture technology, its requirements are stricter, the survival rate of seedlings is lower, and the cost of cultivation is higher, which is not conducive to industrialization and large-scale production and cultivation of A. Cutting seedlings, but the traditional cutting seedlings make the rooting time of the branches longer, the rooting rate and survival rate are low, and it is not conducive to the industrial production of Chinese fir. For this reason, it is often necessary to use rooting To adjust the characteristics of the cloverleaf stems, promote the rooting rate of the cloverleaf plants, further improve the survival rate of the cutting seedlings of the cloverleaf plants, and reduce the cost of factory production

[0004] But, by the application of currently commercially available rooting agent, it is found that it has the following disadvantages: 1. the base of the cuttings after the rooting agent is processed is perishable, and the disease resistance and disease prevention ability are poor; Surviving seedlings have a higher mortality rate after transplanting; ③The cost of commercially available rooting agent products is relatively expensive, which in turn leads to higher factory production costs; ④At present, commercially available rooting agents are used for rooting treatment of cloverleaf plants After that, the rooting time is still relatively long, which is not conducive to factory and large-scale rapid production
