Zanthoxylum nitidum container cutting seedling raising method

Abstract

The invention discloses a zanthoxylum nitidum container cutting seedling raising method. The zanthoxylum nitidum container cutting seedling raising method comprises the following steps: S1, selecting a zanthoxylum nitidum plant as a seed tree, cutting off branches with the thickness of 0.6-2cm, and removing lateral branches; S2, dividing cuttings into black, brown and green cuttings according to the color of the epidermis of the branches, bundling 30-50 cuttings with the same color into one bundle, and soaking the cuttings in an indolebutyric acid solution; S3, preparing a seedling culture substrate according to a ratio, disinfecting, airing until the seedling culture substrate is dry, and putting into seedling culture containers; S4, inserting the cuttings into the seedling raising substrate, inserting one cutting into each seedling raising container, wherein the cutting depth is controlled, and it is guaranteed that two or more bud points are all inserted into the substrate for cutting; and S5, spraying water mist, shading, spraying fertilizer water, and outplanting and transplanting after seedlings are grown for 180-210 days. The zanthoxylum nitidum container cutting seedling raising method can effectively shorten the seedling growing period of the radix zanthoxyli, promote rooting of the cuttings, improve the seedling rate and the seedling quality, and has important significance on promoting production and industrial development of radix zanthoxyli medicinal materials.

Description

technical field [0001] The invention relates to the fields of Chinese medicinal material breeding technology and agricultural planting technology. More specifically, the present invention relates to a method for raising seedlings by cutting of double-faced needle container. Background technique [0002] Liangmianzhen is an authentic medicinal material in Guangxi. It is derived from the dried root of Zanthoxyl umnitidum (Roxb.) DC, a plant of the genus Zanthoxyl umnitidum (Roxb.) DC in the Rutaceae family. Falling injury, stomach pain, toothache, rheumatic arthralgia, poisonous snake bite, external treatment of burns and scalds. Guangxi is a province with a large resource, production and sales of liangmianzhen. The liangmianzhen plants are distributed in different climate zones in Guangxi, and the liangmianzhen medicinal material produced in Guangxi has the highest content of chlorinated limpetine. However, for a long time, the medicinal materials of LMZ have been sourced f...

Problems solved by technology

There is a layer of oil on the surface of Liangmianzhen seeds, which is easy to lose oil and is difficult to preserve for a long time, so it can only be harvested and sowed at the same time; at the same time, the seeds are dormant, and there are water absorption obstacles, immature embryos, germination inhibitors, etc., and the germination rate is low and germination It takes a long time, so the seedlings cannot meet the needs of large-scale cultivation

Container cutting seedling raising technology has been successfully applied to a large number of woody plants, such as Chinese pine, masson pine, golden camellia, etc. Container seedlings have a short seedling cycle, can supply seedlings every year, and the quality of seedlings is high, and the process of seedling transportation is not easy to damage the root system. Transplanting has the advantages of easy survival, high production efficiency, and high degree of mechanization. However, it is difficult to form strong seedlings when the conventional container cutting seedling cultivation technology is applied across varieties to L. chinensis. This is because the rooting time of L. a. The number is small, generally there are only 3 to 5 branches per branch, and a large amount of fertilizer is required after rooting, and the growth rate of branches is slow
