Description

Technical Field

[0001] The invention belongs to the technical field of edible and medicinal plant planting, and particularly relates to a method for promoting the germination of broom. Background Art

[0002] Cagarana sinica (Buc'hoz) Rehder is a genus of the Leguminosae family, also known as Caragana, a shrub about 2 meters high. It is distributed in Hebei, Shaanxi, Jiangsu, Jiangxi, Zhejiang, Fujian, Henan, Hubei, Hunan, northern Guangxi, Sichuan, Guizhou, and Yunnan in my country. It grows on hillsides and thickets. It is a widely distributed and highly adaptable plant. It has a prominent taproot, a well-developed root system, and a strong root sprouting ability. New plants can sprout wherever the root system reaches. It is often scattered in the forest edge or forest window in the form of sheets or islands. The corolla is yellow and the flowers are dense, which can be used for viewing or as a hedge. The flowers are rich in various nutrients. The crude protein content of fresh flower buds is 3.84%, and the crude fiber content is 1.80%. It contains VB2 and VC; it contains macroelements such as P, S, K, Ca, Mg and Na, and trace elements such as Fe, Zn, Cu and Mn; it contains 16 kinds of amino acids, and the total amino acid content is 3.19%. One kilogram of fresh flowers is sold for 100-300 yuan, which has high edible value and economic value. The root can also be used as medicine. It is a shrub species with high ornamental value and both food and medicine. It shoots out once a year (occasionally twice), with a growth of about 10-30cm, an average of 17cm, and a low annual growth. The amount of flowers of the broom is significantly correlated with the growth of side branches. The more side branches, the more flowers it produces. Therefore, it is necessary to increase the growth of branches and the amount of side branches to increase flower production and increase its economic value. Summary of the invention

[0003] The main purpose of the present invention is to provide a technical solution to the problem of low growth of broom branches. The technical solution of the present invention can promote the germination of the apical buds and lateral buds of the broom, start the second to third sprouting, promote the growth of new shoots, the number of new shoots and the germination of new leaves, thereby increasing the growth of side branches and the flower yield.

[0004] The present invention specifically provides the following technical solutions:

[0005] On the one hand, the present invention provides a germination promoter of broom. The germination promoter is prepared by adding 0.2-0.6g of gibberellin, 2g of potassium dihydrogen phosphate and 5-20ml of light carbon core fertilizer to 1L of water to obtain solution A. 2-5ml of soapberry soaking liquid is added to solution A to obtain the germination promoter. The preparation method of the soapberry soaking liquid is as follows: collecting ripe soapberry fruits, removing seeds, breaking the peels and soaking them in clean water, the solid-liquid ratio of the peels to water is 1:1.5, soaking for 3d, kneading until foam appears, filtering, and obtaining a filtrate, which is the soapberry soaking liquid.

[0006] On the other hand, the present invention provides a lignification promoter for new shoots of gentiana, which contains 3-5g of potassium dihydrogen phosphate, 0.8-1g of paclobutrazol and 2ml of the soapberry soaking solution per liter of the promoter.

[0007] Furthermore, the present invention provides the use of the germination promoter in promoting the sprouting of branches from the terminal buds and lateral buds of Broom.

[0008] Furthermore, the present invention provides the use of the promoter in promoting lignification of new shoots of Broom.

[0009] Furthermore, the present invention provides a method for promoting the sprouting of branches from terminal buds and lateral buds of broom. When the current year branches of broom stop growing and form terminal buds and before the leaves fall off, the sprouting promoter is sprayed three times continuously. The whole plant of broom is sprayed, and each spraying is spaced 6-10 days apart. 40-50 kg is sprayed per mu.

[0010] Furthermore, the present invention provides a method for promoting lignification of new shoots of broom. When the new shoots of broom emerge, the promoter is sprayed three times continuously. The whole plant of broom is sprayed, each spraying is performed at an interval of 7-10 days, and 40-50 kg is sprayed per mu.

[0011] The technical effects achieved by the present invention are:

[0012] By applying the germination promoting agent provided by the present invention to broom, the secondary sprouting and new shoot growth of broom branches can be promoted, and the sprouting growth is changed from one time a year to 2-3 times a year, thereby increasing the amount of lateral branches and growth of broom, and then increasing the amount of flowers and increasing economic benefits.

[0013] After being treated with a sprout promoter, the broom achieves secondary sprouting and growth. When the young shoots grow to a certain extent, lignification needs to be promoted, otherwise it is easy to grow too long, and the terminal buds are difficult to form or form late before winter, which not only affects the differentiation of flower buds, but also makes it difficult for young branches to survive the winter, which will affect the flower yield in the second year. Therefore, the application of a new shoot lignification promoter not only increases the amount of side branches and growth, but also promotes the increased side branches to breed flower buds, thereby truly increasing the flower yield in the second year.

[0034] The present invention further illustrates the implementation effect through the following experiments:

[0035] 1. Prepare corresponding sprout promoters and new shoot lignification promoters according to the examples and comparative examples

[0036] 2. Application of germination promoter

[0037] (1) When the current year's branches of broom stop growing and form terminal buds, apply germination promoters before the leaves fall off. Before spraying, remove weeds and loosen the soil.

[0038] (2) Choose a day without rain, shake the germination promoter and spray it evenly on the plants, including leaves and stems, with a sprayer. After the first spraying, spray the second time after 6 days, and the third time after 10 days, spraying 40-50 kg per mu. Set up 20 plants without spraying germination promoter as a control, and treat 20 plants with different germination promoters. On the 10th day after the third spraying, investigate the number of new shoots sprouted, the number of plants with new shoots sprouted, the number of new leaves sprouted, and the length of new shoots of the control and germination promoter-treated plants, and calculate the germination promotion rate, the average number of new shoots sprouted per plant, the average number of new leaves sprouted per plant, and the average new shoot growth.

[0039] Promotion rate of sprouting % = number of plants with sprouting new shoots / total number of treated plants × 100

[0040] Average number of new shoots per plant = total number of new shoots per treated plant / total number of treated plants

[0041] Average number of newly sprouted leaves per plant = total number of newly sprouted leaves per treated plant / total number of treated plants

[0042] Average new shoot growth = total new shoot length of treated plants / total number of new shoots sprouted

[0043] The data survey and statistical results are shown in Table 1.

[0044] 3. Application of new shoot lignification promoter

[0045] Promote the lignification of new shoots: After the new shoots emerge, reduce the number of watering times for the plants, spray the new shoot lignification promoter, choose a rainy day, shake the promoter evenly and use a sprayer to spray the new shoot lignification promoter evenly on the plants, including the leaves and stems, and spray the whole plant. After the first spraying, spray the second time after an interval of 7 days, and the third time after an interval of 7 days, spraying 40-50kg per mu. 15 days after the end of the application of the promoter, observe the color of the leaves and branches, whether the terminal buds are formed, the color of the cross-section of the branches, and the texture of the leaves to judge the degree of lignification. The higher the degree of lignification of the new shoots of the broom, the more cold-resistant it is, and the stronger its ability to breed flower buds, so it is necessary to promote lignification to increase the yield of flowers. Determination of the degree of lignification: if the terminal bud is formed, the leaves are dark green, the leaves are hard, the branches turn from white to red or gray, and the woody pith accounts for a high proportion in the cross-section of the branches, the degree of lignification is high. On the contrary, if the terminal bud is not formed, the leaves are light green, the texture is soft, the branches are white, and the cross-section of the branches is green for a large proportion, the degree of lignification is low.

[0046] Table 1 Effects of different germination promoters on broom

[0047]

[0048] From Table 1 and Figure 1-4It can be seen that when the germination promoting agent of Examples 1-3 of the present invention is used, the germination promotion rate of the broom is significantly improved compared with that of the comparative example 1-2. In particular, under the conditions of Example 3, the germination rate reaches 100% 10 days after the treatment, the number of new shoots is as high as 46, the number of new leaves is as high as 368, the length of new shoots is as high as 27 cm, the average number of new shoots per broom plant is 14, the average number of new leaves per broom plant is 135, and the average length of new shoots is 8.1 cm, which are all significantly higher than those of the comparative examples 1-2 and CK.

[0049] Methods for promoting new shoot lignification: The lignification experiment set up three treatments and one control. The results are as follows Figure 5-8 As shown, M1 treatment was spraying with potassium dihydrogen phosphate solution + soapberry soaking solution, M2 treatment was spraying with paclobutrazol solution + soapberry soaking solution; M3 treatment was spraying with potassium dihydrogen phosphate solution + paclobutrazol + soapberry soaking solution. After one treatment, spraying had the effect of promoting lignification, and the effect was ranked as M3>M2 and M1>control. After treatment with the accelerator, the leaf color turned dark green, the stem turned from white to dark, the terminal bud was formed, and the proportion of woody pith in the cross section of the branch was high. The branches of the control (without any treatment) were young and tender, with poor lignification, no terminal bud formed, long internodes, and green cross section of the branch.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
