Description

Technical Field

[0001] The invention belongs to the technical field of agricultural drugs, and particularly relates to the use of ethionine in preventing and controlling foreign matter in the planting of Epimedium plants. Background Art

[0002] Epimedium brevicornum, also known as Xianlingpi, Sanzhi Jiuyecao, etc., is a plant of the genus Epimedium of the Berberidaceae family. It was first recorded in the "Shennong Bencao Jing" and has a long history of application. Its dried leaves are used as medicine, which has the effects of nourishing kidney yang, strengthening bones and tendons, and removing rheumatism. There are 40 species of Epimedium plants in China, of which 4 species are included in the "Chinese Pharmacopoeia" as Epimedium medicinal materials: Epimedium, Sagittae, Wollose Epimedium, and Korean Epimedium; in addition, Wushan Epimedium is included in the "Chinese Pharmacopoeia" as a single variety, and Qianling Epimedium and Coarse-haired Epimedium are included in the "Guizhou Provincial Traditional Chinese Medicine Standard". Epimedium is also a medicinal plant that can be used in health food approved by the Ministry of Health (now the National Health Commission) (No. 51 in 2002), and is a typical medicinal and edible plant resource. In recent years, innovative Chinese medicines with epimedium as the main raw material have made Epimedium plants highly valued and become one of the medicinal plants with the most development potential in China.

[0003] At present, several varieties such as sagittaria and pubescent epimedium have achieved large-scale seedling cultivation and planting. However, in the production of epimedium seedlings, due to the long-term maintenance of suitable temperature and high humidity, the growth of debris is often induced. The debris is mainly moss plants such as liverworts. Among them, liverworts have fast reproduction speed, fast growth speed, large growth volume, and are very easy to cover the surface of the substrate, causing the substrate to be in a high-humidity state for a long time; the rhizoids of liverworts are attached and inserted into the substrate and compete with epimedium for nutrients with the thallus structure covering the surface of the substrate. If prevention and control are not timely, it will soon break out on a large scale and inhibit the growth of epimedium seedlings, reducing the quality of seedlings. It has been observed that in the seedling tray full of liverworts, epimedium plants are short and have few leaves. Therefore, in the production of epimedium seedlings, a method for efficiently and quickly removing liverworts is urgently needed to improve the quality of seedlings and achieve efficient seedling cultivation. Summary of the invention

[0004] The problems existing in the prior art are: in the prior art, the method for preventing and controlling liverwort during the cultivation of Epimedium plants is usually spraying Bordeaux mixture, but it is time-consuming, requires many sprays, has low prevention effect, and also inhibits the growth of Epimedium seedlings; manually pulling out liverwort is time-consuming and labor-intensive, and difficult to pull out completely.

Figure 2 The middle arrow points to the reproductive structure of the liverwort. The results show that the dead leaves can be easily pulled out after being treated with ethyl allicin solution 1 for 7 days. The dead leaves can be used as nutrients for the epimedium seedlings after being moistened and rotted on the surface of the substrate by watering, and the reproductive structure of the liverwort, namely the male and female receptacles, can be easily pulled out.

[0090] (2) Samples of Marchantia polyphylla were collected from three locations in the seedling trays of the blank control group and the manual removal group 15 days after the application of ethoxylated solution 1 to ethoxylated solution 5, and from three locations in the seedling trays of the blank control group and the manual removal group. All the Marchantia polyphylla in the sampling points were pulled out and their fresh weights were weighed. The fresh weight control rate of Marchantia polyphylla was calculated based on the fresh weights of the Marchantia polyphylla. The calculation formula is shown in Formula 1, and the calculation results are shown in Table 2.

[0091] Fresh weight control rate of Marchantia solani = (fresh weight of Marchantia solani in the manual removal group - fresh weight of Marchantia solani applied with ethyl allicin solution) / fresh weight of Marchantia solani in the manual removal group × 100% Formula 1.

[0092] (3) The number of leaves of the Epimedium pubescent seedlings in the seedling trays 15 days after the application of ethoxylated solutions 1-5, as well as in the seedling trays of the blank control group and the manual removal group were counted, and the leaf damage rate of the Epimedium pubescent seedlings was calculated. The calculation formula is shown in Formula 2, and the calculation results are shown in Table 2.

[0093] Leaf damage rate of Epimedium pubescens seedlings = number of leaves damaged by phytosanitizing agents / total number of leaves × 100% Formula 2 Table 2 Results of fresh weight control rate of Marchantia polyphylla and leaf damage rate of Epimedium pubescens seedlings 15 days after application of ethoxylated solution 1-5

[0094]

[0095] Note: Different lowercase letters after the data in the same column indicate significant differences (P<0.05).

[0096] As shown in Table 2, the results showed that after the 15th day of applying ethionin solution 1 to ethionin solution 5, ethionin solution 1 to ethionin solution 5 showed obvious selectivity to liverwort, among which, the fresh weight control rate of liverwort by applying ethionin solution 1, ethionin solution 2, ethionin solution 3 and ethionin solution 4 was above 80% and there was no significant difference. There was no significant difference in the leaf damage rate of Epimedium pubescens seedlings by applying ethionin solution 3, ethionin solution 4 and ethionin solution 5. However, the leaf damage rate of Epimedium seedlings by applying ethionin solution 1 was as high as 32.2%, and the leaf damage rate of Epimedium seedlings by applying ethionin solution 2 was 19.08%. The leaf damage rate of Epimedium seedlings by ethionin solution 1 and ethionin solution 2 was significantly different from that of ethionin solution 3, ethionin solution 4 and ethionin solution 5.

[0097] Example 2

[0098] Example 2.1 provides a method for promoting the growth of Epimedium pubescens seedlings, and the specific steps of the method are as follows:

[0099] (1) Spray the ethoxylated solution 1 on the corresponding seedling trays in the greenhouse to apply the pesticide to the Epimedium pubescens seedlings and Marchantia polyphylla in the seedling trays for 30 days; at the same time, the seedling trays without spraying the ethoxylated solution and without manual removal of Marchantia polyphylla were used as the blank control group; the seedling trays with manual removal of Marchantia polyphylla were used as the manual removal group. Three parallel groups were set up in each group, in which the coverage area and growth of the Epimedium pubescens seedlings and Marchantia polyphylla in the seedling trays were similar. The area of ​​the seedling tray was 27 cm × 53 cm, and the Marchantia polyphylla covered the surface of the seedling tray, that is, at the base of the Epimedium pubescens seedlings. The seedling trays covered with Marchantia polyphylla were selected, that is, the Marchantia polyphylla leaf-like structure covered the surface of the seedling tray, and the Epimedium pubescens seedlings had two true leaves (belonging to the seedling stage).

[0100] The spraying method of the ethionine solution is: spray the ethionine solution on the Marchantia polyphylla in the seedling tray, spray it on the surface of the leaf blades or the roots of the Marchantia polyphylla, until the ethionine solution on the surface of the leaf blades of the Marchantia polyphylla drips down, and the spraying is completed. It is forbidden to spray or water the Epimedium plants within 1 day after application.

[0101] It should be noted that during the application of pesticides, the substrate temperature in the greenhouse was 19-25°C, the substrate relative humidity in the greenhouse was 60%, and there was no strong wind in the greenhouse.

[0102] (2) After the 30th day of applying the ethionine solution 1, the liverwort relapsed after 20 days of continuous observation. Then the ethionine-compound fertilizer solution was applied until the 50th day (i.e., the ethionine-compound fertilizer solution was applied for 20 days).

[0103] The preparation method of the ethionine-compound fertilizer solution is as follows: 2 mL of ethionine emulsifiable concentrate and 998 mL of compound fertilizer solution are mixed to obtain the ethionine-compound fertilizer solution. The preparation method of the compound fertilizer solution is as follows: 3 g of urea, 3 g of potassium dihydrogen phosphate and water are mixed and the volume is adjusted to 1000 mL to obtain the compound fertilizer solution.

[0104] It should be noted that in step (2), after the 30th day of applying the ethiocarb solution 1, the observation was continued for 20 days. If the recurrence of Marchantia polyphylla was observed, the ethiocarb solution 1 was used again once. The recurrence of Marchantia polyphylla refers to the appearance of new Marchantia polyphylla thallus structures on the surface of the matrix, which is considered to be a recurrence.

[0105] If there is no recurrence of Marchantia odorata, the compound fertilizer solution is applied until the 50th day (i.e., the compound fertilizer solution is applied for 20 days), wherein the preparation method of the compound fertilizer solution is: 3g urea, 3g potassium dihydrogen phosphate and water are mixed and the volume is fixed to 1000mL to obtain the compound fertilizer solution;

[0106] If there is a recurrence of liverwort, apply the ethyl allicin-compound fertilizer solution until the 50th day (i.e. apply the ethyl allicin-compound fertilizer solution for 20 days).

[0107] The spraying method of ethoxylated-compound fertilizer solution or compound fertilizer solution is: spray the surface of the seedling tray until water flows out from the bottom of the substrate of the seedling tray, and the spraying is completed. If water flows out from the bottom of the substrate of the seedling tray, it means that the roots and leaves of Epimedium have been sprayed.

[0108] Example 2.2 provides a method for promoting the growth of Epimedium pubescens seedlings, and the specific steps of the method are as follows: the difference from Example 2.1 is that the ethionine solution 1 is replaced by the ethionine solution 2. Example 2.2 shows the phenomenon of Marchantia polyphylla recurrence.

[0109] Example 2.3 provides a method for promoting the growth of Epimedium pubescens seedlings, and the specific steps of the method are as follows: the difference from Example 2.1 is that the ethionine solution 1 is replaced by the ethionine solution 3. Example 2.3 shows the phenomenon of Marchantia polyphylla recurrence.

[0110] Example 2.4 provides a method for promoting the growth of Epimedium pubescens seedlings, and the specific steps of the method are as follows: the difference from Example 2.1 is that the ethionine solution 1 is replaced by the ethionine solution 4. Example 2.4 shows the phenomenon of Marchantia polyphylla recurrence.

[0111] Example 2.5 provides a method for promoting the growth of Epimedium pubescens seedlings, and the specific steps of the method are as follows: the difference from Example 2.1 is that the ethionine solution 1 is replaced by the ethionine solution 5. Example 2.5 shows the phenomenon of recurrence of Marchantia polyphylla.

[0112] Technical effect evaluation

[0113] (1) After the 15th day of applying the ethionin solution, after the 30th day of applying the ethionin solution, and after the 50th day of applying the compound fertilizer solution or the ethionin-compound fertilizer solution (i.e., 20 days after applying the compound fertilizer solution or the ethionin-compound fertilizer solution), the number of leaves of the Epimedium pubescens seedlings, the maximum leaf length of the Epimedium pubescens seedlings, and the maximum leaf width of the Epimedium pubescens seedlings in Examples 2.1-2.5, the blank control group, and the manual removal group were recorded respectively. Among them, after the 15th day, the 30th day, and the 50th day, the number of leaves of the Epimedium pubescens seedlings, the maximum leaf length of the Epimedium pubescens seedlings, and the maximum leaf width of the Epimedium pubescens seedlings in the manual removal group were as shown in Table 3.

[0114] The leaf number inhibition rate, leaf length inhibition rate and leaf width inhibition rate of the Epimedium pubescentis seedlings in Examples 2.1-2.5 and the blank control group were calculated. The results are as follows: Figure 3 , Figure 4 and Figure 5 shown.

[0115] Growth inhibition rate of the number of leaves of Epimedium pubescens seedlings = (number of leaves of Epimedium pubescens seedlings in the manual removal group - number of leaves of Epimedium pubescens seedlings in the example) / number of leaves of Epimedium pubescens seedlings in the manual removal group × 100%. A growth inhibition rate of less than 10% means no significant phytotoxicity.

[0116] The growth inhibition rate of the maximum leaf length of Epimedium pubescens seedlings = (maximum leaf length of Epimedium pubescens seedlings in the manual removal group - maximum leaf length of Epimedium pubescens seedlings in the example) / maximum leaf length of Epimedium pubescens seedlings in the manual removal group × 100%. A growth inhibition rate of less than 10% means no significant phytotoxicity.

[0117] Growth inhibition rate of maximum leaf width of Epimedium pubescens seedlings = (maximum leaf width of Epimedium pubescens seedlings in manual removal group - maximum leaf width of Epimedium pubescens seedlings in Example) / maximum leaf width of Epimedium pubescens seedlings in manual removal group × 100%. When the growth inhibition rate is less than 10%, there is no significant phytotoxicity.

[0118] (2) Taking photos to record the growth status of the Epimedium pubescens seedlings in the seedling tray of the blank control group, as well as the growth status of the Marchantia polymorpha and Epimedium pubescens seedlings in the seedling tray of Example 2.4 after 1 day, 2 days, 5 days, 6 days, 7 days, 15 days, 30 days and 50 days. The results are as follows: Figure 6 Table 3. Number of leaves, maximum leaf length and maximum leaf width of Epimedium pubescens seedlings in the manual removal group after 15 days, 30 days and 50 days

[0119]

[0120] like Figure 3 , Figure 4 and Figure 5 As shown, Figure 3 The changes in the number of leaves of Epimedium pubescens and the growth inhibition rate of the leaves in Examples 2.1-2.5. Figure 4 The maximum leaf length and the growth inhibition rate of the maximum leaf length of Epimedium pubescens in Examples 2.1-2.5 are shown. Figure 5 The maximum leaf width and the growth inhibition rate of the maximum leaf width of Epimedium pubescens in Examples 2.1-2.5 are shown in Figure 2.1-2.5. The results show that the inhibition rate of Examples 2.1-2.5 on Marchantia polyphylla decreases over time, and the growth inhibition rate of the number of leaves and the leaf width is less than 10% at 30 days (it can be considered that there is no inhibitory effect on the growth of Epimedium pubescens seedlings, that is, it is safe for Epimedium pubescens); when the ethyl allicin-compound fertilizer solution is applied to the 50th day, the growth inhibition rates of the number of leaves, the maximum leaf length, and the leaf width of the treatment group are all less than or equal to 0, and it can be considered that this method can promote the growth of Epimedium pubescens. In the blank control group, the inhibition rate of the maximum leaf length and leaf width increased with time, and the inhibition rate of the leaf number was in a trend of first increasing and then decreasing, but the decreasing trend was slow; at 15 days, the blank control group had a significant inhibitory effect on the growth of the number of leaves of the seedlings, and its inhibition rate reached 29.79%, which was greater than that of the treatment group; 30 days after the application of the pesticide, the blank control group had a significant inhibitory effect on the number of leaves, leaf length and leaf width of the seedlings (the growth inhibition rate was greater than 20%). It can be seen that with the growth of the liverwort, the stronger the inhibitory effect of the liverwort on the leaf length and leaf width of the epimedium seedlings, the stronger the inhibitory effect of the liverwort on the leaf length and leaf width of the epimedium seedlings, and the more obvious the inhibitory effect on the growth of the leaf number. After 50 days of this method, the average number of leaves of the seedlings in the treatment group was more than 6, the average maximum leaf length was more than 4.34cm, and the maximum leaf width was more than 3.80cm.

[0121] like Figure 6 As shown, Figure 6 The growth status of the Marchantia polyphylla and Epimedium pubescens seedlings in the seedling tray of Example 2.4, wherein A to I are the growth status of the Marchantia polyphylla and seedlings before application, 1 day, 2 days, 5 days, 6 days, 7 days, 15 days, 30 days and 50 days later. The results showed that spraying the compound fertilizer solution 30 days after applying the ethoxylated solution 4 had a good control effect on the Marchantia polyphylla and promoted the good growth of the Epimedium pubescens seedlings.
