Description

Technical Field

[0001] The present invention relates to an insect-resistant cultivation medium. The present invention also relates to an insect-resistant method. Background Art

[0002] The Atlas of Wild Orchids in Taiwan, China points out that there are about 4,600 species of plants in Taiwan, China, of which more than 400 are orchids, accounting for one-tenth. It can be seen that Taiwan, China has rich orchid diversity. In 2022, the total value of flower exports from Taiwan, China reached US$224 million, of which Phalaenopsis and Oncidium accounted for 77.5% of the total export value. It can be seen that orchids are an important economic crop in Taiwan, China.

[0003] Taiwan, China, has a hot and humid climate. Although it is suitable for the growth of orchids, it is also suitable for the growth and reproduction of various insects. Therefore, during the orchid cultivation process, there is a possibility that the plants are attacked by pests. In addition to reducing the quality and value of the product, it also causes the trouble of upgrading quarantine measures when the plants are exported to other countries, and even direct returns of the entire container, resulting in significant economic losses. Therefore, insect resistance is an important task in orchid cultivation.

[0004] Current anti-insect methods include using 16-mesh or 32-mesh insect-proof nets, installing mollusk anti-climbing devices on the planting bed supports, regularly replacing sticky insect boards, and regularly spraying insect-resistant agents. However, these methods are highly dependent on manpower, so more efficient anti-insect measures remain to be developed. Summary of the invention

[0005] To solve the above problems, the present invention provides an insect-resistant cultivation medium, comprising: a plastic medium body having a plurality of pores interconnected with each other, and an insect-resistant agent uniformly dispersed and fixed in the pores; wherein the plastic medium body comprises at least one cultivation medium solid, the insect-resistant agent has an insect-resistant component, and the insect-resistant agent is a sustained-release formulation.

[0006] The molding medium of the present invention is not only convenient for implanting and supporting plant seedlings, such as orchid seedlings, to facilitate growth, but also has pores that can accommodate and fix evenly dispersed insecticides, and through the slow release of insecticide components, can provide insecticide protection during the growth of plant seedlings for the roots buried in the cultivation medium during the cultivation process, thereby eliminating the problem of traditional insecticides only being provided on the surface of the cultivation medium, resulting in a lack of protection inside the cultivation medium. In addition, the insect-resistant cultivation medium of the present invention has been proven to provide comprehensive insecticide protection for the plant root system for a long time, and can eliminate the labor cost of regularly replenishing insecticides and reduce the amount of insecticides used, so as to further reduce the cultivation cost of the plant, and is also more friendly to the natural environment and the health of the cultivation personnel.

[0057] Figure 1 It is a cross-sectional schematic diagram and a partially enlarged schematic diagram of the insect-resistant cultivation medium of the present invention. DETAILED DESCRIPTION

[0058] Several operation modes are provided below to illustrate the implementation methods of the present invention. Those skilled in the art can easily understand the advantages and effects that can be achieved by the present invention through the contents of this specification, and make various modifications and changes without departing from the spirit of the present invention to implement or apply the contents of the present invention.

[0059] Example 1: Insect-resistant cultivation medium

[0060] like Figure 1 As shown, the insect-resistant cultivation medium of the present invention comprises a plastic medium body 1 having a plurality of pores 10 interconnected with each other, and an insect-resistant agent 20 uniformly dispersed and fixed in these pores 10; wherein the plastic medium body 1 comprises at least one cultivation medium solid 30, the insect-resistant agent 20 has an insect-resistant component, and the insect-resistant agent 20 is a sustained-release formulation.

[0061] Furthermore, the insect-resistant agent 20 is a plurality of insect-resistant particles, and based on the total weight of the insect-resistant cultivation medium, the content of the molding medium body 1 is 85 weight percent to 99.99 weight percent, and the content of these insect-resistant particles is 0.01 weight percent to 15 weight percent.

[0062] In addition, the center of the molding medium body 1 has a receiving space 40, and the receiving space 40 is connected to the top surface 60 of the molding medium body 1 through a connecting channel 50, and the maximum diameter of the receiving space 40 is greater than the maximum diameter of the connecting channel 50. Finally, the top surface 60 of the molding medium body 1 is C-shaped, which is convenient for placing the plant into the receiving space 40 of the molding medium body 1 from the side wall gap of the molding medium body 1 corresponding to the C-shaped gap.

[0063] Preparation Example 1: Example 2 to Example 4

[0064] This preparation example includes Example 2 to Example 4. The components of the molding medium in each group are the same, all using Quick Plug peat (fertilizer (auxiliary) No. 0776065, 7-03-organic cultivation medium), but the insecticides used are different, as described below:

[0065] Example 2: The solid matter of the cultivation medium (i.e., broken up Pulage peat), the insecticide (i.e., Gold-Linol, Linong Chemical, Taiwan, China, active ingredient: Peripfen, 11% w / v water-based emulsion, sustained-release formulation) and the organic binder are uniformly mixed for at least 5 minutes until visually uniformly mixed, and then compressed and shaped through a mold to obtain the insect-resistant cultivation medium of Example 2; wherein, the total weight of a single insect-resistant cultivation medium of Example 2 is about 10 grams, and the insecticide content of a single insect-resistant cultivation medium is about 0.5 ml of Gold-Linol, that is, a single insect-resistant cultivation medium contains 0.5×11%=0.055 grams of Peripfen.

[0066] Example 3: The solids of the cultivation medium (i.e., broken up Pulage peat), the insecticide (i.e., Zhulebao insect growth regulator granules, Sumitomo Chemical, Japan, active ingredient and content: pyriproxyfen 0.5% w / w, sustained release formulation) and the organic binder are uniformly mixed for at least 5 minutes until visually uniformly mixed, and then compressed and shaped through a mold to obtain the insect-resistant cultivation medium of Example 3; wherein, the total weight of a single insect-resistant cultivation medium of Example 3 is about 10 grams, and the insecticide content of a single insect-resistant cultivation medium is 1 gram, that is, a single insect-resistant cultivation medium contains 1×0.5 / 100=0.005 grams of pyriproxyfen.

[0067] Example 4: Similar to Example 3, the only difference is that the insect-resistant agent content of a single insect-resistant cultivation medium in Example 4 is 0.06 grams, that is, a single insect-resistant cultivation medium contains 0.06×0.5 / 100=0.0003 grams of belipfen.

[0068] Test 1: Insect repellent test

[0069] This insect-proof test includes Comparative Example 1A, Comparative Example 1B, Example 5, Example 6 and Example 7; wherein each group planted 140 orchid seedlings, the ambient temperature was controlled at 28°C to 30°C, the humidity was controlled at 75% to 90%, and the period was 10 weeks. Each group of orchid seedlings was located in the same space, each group had two blocks, and each block contained 7×10 orchid seedlings. In addition, the orchid seedlings were cultivated at a high density, so each block was adjacent to each other, and each orchid seedling was adjacent to each other, and there was a situation where the leaves were in contact with each other.

[0070] 1. The differences in the test methods of each group are explained as follows:

[0071] (i) Comparative Example 1A and Comparative Example 1B: The insect control methods of Comparative Example 1A and Comparative Example 1B are the same, except that the traditional insect control method is applied to different batches of seedlings, and the time interval between the two batches of seedlings is about 4 days.

[0072] The traditional insect control method is to dilute the insecticide (i.e., Jin-Linolin, 11% water-based emulsion) with water 1500 times to obtain an insecticide dilution, and then regularly water the insecticide dilution at an average interval of 2.5 days, that is, pour about 50 ml of the insecticide dilution into the pot (i.e., in a transparent plastic cup with holes at the bottom), and stop when the water line of the insecticide dilution covers the top surface of the molding medium (i.e., Pulage peat, without insecticide), and the excess insecticide dilution will be gradually discharged from the bottom of the pot (i.e., the holes at the bottom of the transparent plastic cup).

[0073] The weight of the above-mentioned single molding medium is 10 grams, and the water absorption capacity of the single molding medium is about 30 milliliters. Therefore, the single drug absorption amount of the single molding medium is about 30×11%×1 / 1500=0.0022 grams of belipfen, and the total drug absorption amount for 10 weeks is 0.0022×(7×10 / 2.5)=0.062 grams.

[0074] (ii) Examples 5 to 7: The insect-proofing methods of Examples 5 to 7 are similar, the only difference being the insect-resistant cultivation medium used (i.e., Examples 2 to 4, containing insect-resistant agents).

[0075] In Examples 5 to 7, watering was performed regularly at a frequency of 2 to 3 days each time, that is, about 50 ml of water was poured into the pot (i.e., in a transparent plastic cup with holes at the bottom), and the water was stopped after the water line covered the top surface of the insect-resistant cultivation medium (i.e., Examples 2 to 4, containing insecticides). The excess water was gradually discharged from the bottom of the pot (i.e., the holes at the bottom of the transparent plastic cup).

[0076] 2. The evaluation method of the results of this insect-proof test is described as follows:

[0077] The growth of orchid seedlings in each group was observed at the 6th and 10th weeks, and the insect bite rate and total defect rate were calculated. The results are shown in Table 1 and explained as follows.

[0078] (1) Insect bite rate:

[0079] Calculation formula: Insect bite rate (%) = (Number of pests) / 140 × 100%. During the 6th and 10th weeks, if the insect body can be directly seen, or the orchid seedling has visible wounds, the orchid seedling will be marked as being infested and included in the number of pests, and the number of pests in the 6th week will be accumulated to the number of pests in the 10th week.

[0080] 2. Total defect rate

[0081] Calculation formula: Total defective rate (%) = (number of defective products) / 140 × 100%. Orchid seedlings that are damaged by insects and dead will be marked as defective products, for example: orchid seedlings die due to poor quality, or the cause of death of orchid seedlings cannot be ruled out as death by insect bites, for example: orchid seedlings have newly hatched first-instar larvae that are difficult to see with the naked eye, or the insect bites are not obvious or are covered and cannot be observed, and the number of defective products in the 6th week will be accumulated to the number of defective products in the 10th week.

[0082] Table 1: Total dosage of Belipfen used in ten weeks, insect bite rate and total adverse reaction rate of each group

[0083]

[0084] From the comparison of Comparative Example 1A, Comparative Example 1B and Example 5, it can be seen that although all three use Jin-Linongling (11% water-based emulsion), and the content of peripfen in a single insect-resistant cultivation medium of Example 5 (0.055 g) is slightly lower than 0.062 g of Comparative Example 1A and Comparative Example 1B, the insect bite rate and total defect rate of Comparative Example 1A and Comparative Example 1B in the 6th and 10th weeks are significantly higher than those of Example 5. The reason is that the uniform dispersion effect of peripfen brought into the molding medium body through the insect-resistant diluent is not ideal. Therefore, the present invention can effectively improve the insect-resistant effect by pre-mixing the insect-resistant agent into the molding medium body.

[0085] From the comparison between Example 5 and Example 6, it can be seen that although the content of belipfen in a single insect-resistant cultivation medium of Example 6 is only 0.005 / 0.055×100%=9.09% of that in Example 5, which is about one-tenth of the content of belipfen, the insect bite rate and the total defective rate of the two in the 6th and 10th weeks are similar. It can be seen that the use of Zhulebao insect growth regulating granules, that is, insect-resistant granules, can greatly reduce the dosage of belipfen. The reason is judged to be that the insect-resistant granules have a better fixing effect in the molding medium, which can reduce the risk of loss of insect-resistant granules due to regular watering.

[0086] From the comparison between Example 6 and Example 7, it can be seen that although the insect bite rate and the total defective rate of Example 7 in the 6th and 10th weeks are slightly higher than those of Example 6, the content of belipfen in a single insect-resistant cultivation medium of Example 7 is only 0.0003 / 0.005×100%=6% of that of Example 6. It can be seen that the use of insect-resistant granules in solid dosage form can actually further significantly reduce the dosage of belipfen.

[0087] Finally, it is particularly emphasized that the inventor has regularly provided: Jin-Linongling (11% water-based emulsion) (that is, pouring the diluted solution of Jin-Linongling (11% water-based emulsion) into the commercial molding medium for absorption by the commercial molding medium) and Zhulebao insect growth regulating granules (that is, providing the granules to the surface of the commercial molding medium), and compared the insect-resistant effects of the two under the condition of the same dosage of Belipfen (that is, the content of Belipfen in the absorbed dilution is the same as the content of Belipfen in the granules located on the surface of the commercial molding medium), and found that the insect-resistant effect of the Zhulebao insect growth regulating granules is significantly poor. The reason is judged to be that the Zhulebao insect growth regulating granules are only sprinkled on the top surface of the molding medium, and the uniform dispersion effect of Belipfen into the molding medium by watering is not good. Therefore, this insect-proof test did not set up a control group for comparison with the Zhulebao insect growth regulating granules.

[0088] In summary, the present invention can provide long-term and comprehensive root anti-insect efficacy, and has the advantages of reducing the amount of anti-insect agents and eliminating the need for regular spraying of anti-insect agents.
