Embodiment 1

[0031] A method for breeding vine seedlings with nutrition bags, comprising the steps of:

[0032] Step 1 Establish the seedbed: From March to April 2017, Shuitian Township, Mengzi City, Honghe Prefecture, Yunnan Province, between 21°00′ and 23°59′ north latitude, chooses an altitude of 600-900m, with flat terrain, good drainage and ventilation, Several seedbeds shall be established on plots with sufficient light, convenient irrigation and convenient transportation. The area of ​​the plot shall not be less than 20m×30m.

[0033] Step 2 prepares nutritious soil: nutritious soil is mainly formed by mixing vermiculite, decomposed farmyard manure and loam, and the described nutritious soil is first mixed by vermiculite: decomposed farmyard manure: loam mass ratio is 1: 2: 7, and then by 2% Add high-phosphorus-potassium compound fertilizer I to the nutrient soil to make a soil-fertilizer mixture, and finally use 15-20g / m 3 Mix 10% thiazophosphine granules in the soil fertilizer mi...

Embodiment 2

[0045] Table 1 shows the statistical results on the seedling survival rate of on-demand bags and transplanted bags:

[0046] In Table 1, the rate of seedling storage is the ratio of the number of seedlings stored when the seedlings are transplanted to the number of seedlings that emerge after the middle seedlings in the on-demand bag or the transplanting number of transplanted seedlings in the transplanting bag.

[0047] Table 1 Survival rate of seedlings

[0048]

[0049] Referring to Table 1, the survival rate of the customs-clearing rattan seedlings of the on-demand bag and the transplanting bag are all above 90%.

Embodiment 3

[0051] Referring to Table 2, total biomass and seedling height are investigated and compared within three months of transplanting the seedlings raised in nutrition bags and the seedlings raised by direct seeding, and the results of the test are shown in Table 2:

[0052] According to Table 2, compared with direct-seeding seedlings, after transplanting for 90 days, the seedlings raised in nutrition bags eliminated the slow seedling stage, and the seedling height increased by 71.1%, and the biomass increased by 61%.

[0053] In Table 2, the direct-seeding seedlings of the seeds adopt the conventional seedling raising method to grow seedlings. When transplanting, the healthy seedlings with the seedling height and total biomass similar to the raised seedlings in the embodiment of the present invention are manually selected to mark and track, and the slow seedling stage and 60 days and 90 days are counted respectively. days later data;

[0054] The "transplanting of seedlings raise...

Abstract

The invention discloses a method for cultivating marsdenia tenacissima seedlings in a nutrition bag. The method comprises the steps of selecting a ground bed, preparing nutrient soil, loading the soilin the nutrition bag, placing, conducting seed selection, hill seeding/seedling transplanting, conducting seedbed management, transplanting the marsdenia tenacissima seedlings and the like. By meansof establishment of a number of seedbeds, preparation of the nutrient soil, seed selection, hill seeding/seedling transplanting, seedbed management, transplanting of the marsdenia tenacissima seedlings and other measures, the marsdenia tenacissima seedlings are cultivated. Compared with a traditional conventional seedling transplanting method, the method can significantly improve the seedling survival rate by 90% or above, the seedling transplanting by the method is not limited by weather, the rejuvenation period of the marsdenia tenacissima seedlings can be eliminated, and in the same year ofthe transplanting, the biomass of marsdenia tenacissima is increased by 60% or above.

Description

technical field [0001] The invention relates to the technical field of breeding of traditional Chinese medicinal materials, in particular to a method for breeding seedlings of Tongguan rattan in a nutrition bag. Background technique [0002] Tongguan vine is a perennial vine belonging to the genus Milkweed in the Ascaridaceae family. Its stems, roots, and leaves have anti-inflammatory, heat-clearing and detoxifying effects. In recent years, studies have shown that the chemical components such as C21 steroids of Tengguanteng have anti-tumor effects, so the demand for Tengguanteng has gradually increased. In the past, the supply of medicinal materials mainly came from wild natural breeding, which could not meet the rapidly growing demand for medicinal materials. [0003] It can be reproduced in two ways, sexual seed propagation and asexual cutting propagation. The current cultivation mainly propagates the seedlings by seeds, and then transplants the seedlings and propagates t...
