Description

Technical Field

[0001] The invention relates to the technical field of plant planting, and in particular to a jasmine liquid cutting propagation device and a propagation method. Background Art

[0002] The main production areas of jasmine in China are Hengzhou City, Guangxi Zhuang Autonomous Region, Fuzhou City, Fujian Province, Qianwei County, Sichuan Province, and Yuanjiang County, Yunnan Province. Hengzhou City, Guangxi Province is the world's jasmine and jasmine tea production center, with a jasmine planting area of ​​more than 108,000 mu and an annual production of more than 12 million jasmine ornamental potted flowers. The Institute of Flowers of Guangxi Academy of Agricultural Sciences has selected and bred many new and excellent jasmine varieties, such as "Xiangfei No. 2", "Xiangfei No. 3", "Xiangfei No. 4" and "Xiangfei No. 6", which are more valuable than the main variety "Hengxian Double Petal Jasmine" in terms of ornamental potted flower cultivation, scented tea and essential oil processing, with high economic benefits and broad market prospects.

[0003] The traditional propagation method of jasmine is mainly cutting propagation, which is suitable for cutting propagation from April to June each year. Loose, fertile, well-drained fine sand, soil or nutrient soil are selected as cutting substrates. One-year-old mature branches are selected, and the branches are cut into cuttings of about 8-10 cm. The lower leaves are removed, and the base is cut obliquely and soaked in diluted rooting water. After soaking for half an hour, it is taken out and inserted into the sand bed. Rooting and germination take place 2 months after insertion. However, there are some problems in the existing cutting method for propagating jasmine: 1. The cuttings take root slowly and the number of roots is small; cuttings using soil or nutrient soil and other substrates are easy to cause mechanical damage such as root breakage during transplanting, which easily leads to the death of cutting seedlings, and the transplanting survival rate is not high; the seedling acclimatization time is long, the quality of cutting seedlings is low, and the speed of potted formation and listing is slow. 2. The use of substrate or soil for cutting propagation occupies too much space, and the production per unit area is small, which cannot meet the needs of small-scale cutting propagation and is not enough to promote planting among small-scale jasmine growers. 3. When using substrates such as fine sand beds, soil or nutrient soil for cutting, more labor is required during cutting, and manual spraying is often required after cutting to maintain the moisture of the substrate, which wastes labor costs and is high; the use of substrate cutting requires high sterilization of the substrate, and poor disinfection and sterilization can easily cause jasmine cuttings to breed diseases and pests. 4. When using substrates such as fine sand beds, soil or nutrient soil for cutting, when the cuttings are large in size (length ≥ 15 cm), the cutting survival rate is low. Therefore, thinner branches are selected in production, and the cuttings are small in size, resulting in slow formation of cutting seedlings and unsatisfactory formation effects. Meanwhile, the existing cutting method for propagating new and improved varieties of jasmine also has problems such as low rooting rate of cuttings, underdeveloped root system, low survival rate of transplantation, slow formation of cutting seedlings and low quality of seedlings.

[0086] (5) Cuttings: Plant one cutting in each hole. Before cutting, use a wooden stick to make holes in the nutrient soil to a depth of 4-6 cm. Then insert the cuttings into the holes and compact the nutrient soil around the cuttings.

[0087] (6) Management after cutting: Use intermittent spraying to keep the nutrient soil moist in time.

[0088] Comparative Example 2

[0089] The cutting propagation is carried out by the method of cutting in yellow heart soil plug tray, and the cutting method includes:

[0090] (1) Pretreatment of cuttings: Select semi-lignified branches as cuttings, cut the cuttings into a length of 15-22 cm, and leave 2-4 opposite full leaves on the upper part of the cuttings.

[0091] (2) Disinfection of cuttings: Tie the cuttings into bundles and immerse the whole bundle in disinfectant for disinfection. The disinfectant is a mixture of 1.5 g / L potassium permanganate and 1.2 g / L carbendazim wettable powder in a volume ratio of 1:2. Soak the cuttings for 3 minutes, then take out and rinse with clean water for 3 minutes.

[0092] (3) Rooting agent treatment: immerse the base of the cuttings 3-5 cm into rooting water for soaking. The rooting water is 600 mg / L naphthaleneacetic acid and 600 mg / L indole-3-butyric acid, mixed in a volume ratio of 1:1, and soak the cuttings for 3 hours.

[0093] (4) Disinfection of loess soil: Fill the 32-hole seedling tray with loess soil and spray the loess soil with 1.0 g / L of carbendazim wettable powder for sterilization 3 days before cutting. Water the loess soil thoroughly before cutting.

[0094] (5) Cuttings: Plant one cutting in each hole. Before cutting, use a wooden stick to make a hole in the loess soil with a depth of 4-6 cm. Then insert the cutting into the hole and pinch the loess soil around the cutting to make it firm.

[0095] (6) Management after cutting: Use intermittent spraying to keep the soil in the heart of the cuttings moist.

[0098] The methods described in Examples 1-3 were respectively applied in the production of cutting propagation of the main jasmine cultivars (Hengxian double-petal jasmine), with the method of cutting in nutrient soil plug trays as comparative example 1 (CK1), and the method of cutting in yellow heart soil plug trays as comparative example 2 (CK2). That is, the difference between Control 1 and Control 2 lies in the difference in cutting medium and cutting container. 200 jasmine plants were propagated by cutting in each treatment and observed.

[0099] The rooting rate of the main jasmine variety (Hengxian double-petal jasmine) cuttings 40 days after cutting, and the rooting rate, root length and root number of the main jasmine variety (Hengxian double-petal jasmine) cuttings 60 days after cutting were measured. The results are shown in Table 1.

Combined with actual sampling observation, the jasmine cuttage base growth state using the method of the present invention is better, and no mold, rot and pests and diseases phenomenon occur. The present application provides new technical support for the space utilization, program simplification, cost saving and yield improvement of jasmine cuttage propagation production.

[0103] Test Example 2

[0104] The methods described in Examples 1-3 were respectively used in the production of cutting propagation of new and excellent varieties of jasmine, with the method of cutting with nutrient soil plug tray as comparative example 1 (CK1), and the method of cutting with yellow heart soil plug tray as comparative example 2 (CK2). That is, the difference between control 1 and control 2 lies in the difference in cutting medium and cutting container. The rooting rate of new and excellent varieties of jasmine cuttings after 40 days of cutting, and the rooting rate, root length and root number of new and excellent varieties of jasmine cuttings after 60 days were measured, and the results are shown in Table 3. The new and excellent varieties of jasmine for testing include "Xiangfei No. 2", "Xiangfei No. 3", "Xiangfei No. 4" and "Xiangfei No. 6" in Table 2. When conducting the cutting propagation test, four new and excellent varieties of jasmine were cut for each treatment method, and 100 plants of each variety of jasmine were planted. For example, the method of Example 1 is used to plant 100 plants of "Xiang Fei No. 2", 100 plants of "Xiang Fei No. 3", 100 plants of "Xiang Fei No. 4" and 100 plants of "Xiang Fei No. 6".

[0109]

[0110]

[0111] As can be seen from Table 3, the new superior varieties of jasmine cuttings using the method of the present invention for cuttings, the rooting rate of cuttings for 40 days, the rooting rate of cuttings for 60 days, the average root length and the number of roots are significantly higher than those of control 1 and control 2, and the rooting rate, the average root length and the number of roots are important indicators for measuring the cutting effect, and the experimental results fully illustrate that compared with the current traditional cutting method, the method of the present invention is used to carry out the new superior varieties of jasmine cuttings, which is conducive to shortening the rooting time, improving the rooting rate and the rooting quality of cuttings of the new superior varieties of jasmine. Combined with actual sampling observation, the jasmine cuttings base growth state using the method of the present invention is better, and there is no mildew, rot and pests and diseases phenomenon. The application provides new technical support for the space utilization, program simplification, cost saving and yield improvement of jasmine cutting propagation production.

[0112] Test Example 3

[0113] The control (CK) was propagated by cuttings in the same manner as in Example 2, except that the control group was not heated but cultured at natural temperature.

[0114] The methods described in Examples 1-3 were respectively used in the production of jasmine cutting propagation, and the liquid cutting method without heating was used as a control (CK). That is, the difference between the controls was that the temperature control at the base of the cuttings was different. 200 jasmine plants were propagated by cuttings in each treatment and observed.

[0115] The rooting rate of the main jasmine variety (Hengxian double-petal jasmine) cuttings 40 days after cutting, and the rooting rate, root length and root number of the main jasmine variety (Hengxian double-petal jasmine) cuttings 60 days after cutting were measured. The results are shown in Table 4.

[0116] Table 4 Effects of different liquid cutting temperatures on rooting rate and growth indexes of cuttings

[0117]

[0118] As can be seen from Table 4, the rooting rate of 40 days after cutting, the rooting rate of 60 days after cutting, the average root length and the number of roots of the jasmine cuttings cut by the method of the present invention are significantly higher than those of the control. The rooting rate, the average root length and the number of roots are important indicators for measuring the cutting effect. The experimental results fully illustrate that in the jasmine liquid cutting, the heating method is adopted in the cutting slot, which is more conducive to shortening the rooting time of the jasmine cuttings, improving the cutting rooting rate and the rooting quality of the cuttings.

[0119] Test Example 4

[0120] In this test example, the cutting propagation method of control 1 (CK1) is different from that of embodiment 2 in that root-promoting nutrient solution is used throughout the cutting process for cutting propagation.

[0121] The cutting propagation method of control 2 (CK2) is different from that of embodiment 2 in that the cutting propagation is carried out entirely using a seedling-strengthening nutrient solution.

[0122] The methods described in Examples 1-3 were respectively used in the production of jasmine cutting propagation, and the methods of using all root-promoting nutrient solution and all seedling-strengthening nutrient solution in the cutting process were respectively used as control 1 (CK1) and control 2 (CK2). That is, the difference between the controls lies in the different nutrient solutions used. 200 jasmine plants were propagated by cuttings for each treatment and observed.

[0123] The rooting rate of the main jasmine variety (Hengxian double-petal jasmine) cuttings 40 days after cutting, and the rooting rate, root length and root number of the main jasmine variety (Hengxian double-petal jasmine) cuttings 60 days after cutting were measured. The results are shown in Table 5.

[0124] Table 5 Effects of different nutrient solution treatments on rooting rate and growth indexes of cuttings

[0125]

[0126] As can be seen from Table 5, the jasmine cuttings cut by the method of the present invention have an average root length and a root number that are significantly higher than those of the control 1, and the rooting rates of the cuttings 45 days and 60 days after cutting are significantly higher than those of the control 2. The rooting rate, the average root length and the root number are important indicators for measuring the cutting effect. The experimental results fully illustrate that the root-promoting nutrient solution and the seedling-strengthening nutrient solution in the present invention are used in stages, which is beneficial to shortening the rooting time of the jasmine cuttings, improving the rooting rate of cuttings and the rooting quality of the cuttings. The rooting nutrient solution can better promote the formation of the root system of the new cuttings, while the seedling-strengthening nutrient solution focuses more on the further growth of the root system after the cuttings take root.
