Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sea-buckthorn planting, and particularly relates to a sea-buckthorn planting method for preventing and treating diseases and pests. BACKGROUND

[0002] Sea-buckthorn is a deciduous shrub fruit of Elaeagnaceae. The height of sea-buckthorn is 1-2.5 m, the flowering period is from April to May, and the fruit maturation period is from September to October. Sea-buckthorn has the characteristics of drought tolerance, wind and sand resistance, and can survive in saline-alkali land, so it is widely used for water and soil conservation. The roots, stems, leaves, flowers, fruits and seeds of sea-buckthorn can be used as medicine, especially the fruits contain rich nutrients and bioactive substances, and the vitamin content is high, so it is known as the "king of vitamin C". Modern medical research shows that sea-buckthorn has the effects of relieving fatigue, enhancing memory, anti-aging, enhancing physical fitness, improving immunity, softening heart and cerebral blood vessels, etc.

[0003] The wood borer of sea-buckthorn is a species of the genus Xylosandrus in the family of wood borer of Lepidoptera, the adult body length is 17-19 mm, the wing span is 38-39 mm, the body color is grayish brown with black stripes, the antennae are filamentous compound eyes black; the larvae are small and pink all over; the growth cycle is mostly one generation per 4 years, and the generations overlap. The wood borer of sea-buckthorn belongs to a boring pest, mainly harming the roots and stems of sea-buckthorn with the larvae, the initial larvae often gather in the trunk, and the mature larvae pupate in the soil, thereby affecting the transportation of water and nutrients, causing the tree to weaken or die. Due to the damage of the wood borer of sea-buckthorn, a large area of sea-buckthorn trees weaken or even die, the damage of the wood borer of sea-buckthorn has affected the development of the three benefits of sea-buckthorn forest distribution area and the development of industrial value, and the damage of a single tree is more than 100 individuals, if not controlled in time, it will bring devastating damage to the sea-buckthorn forest.

[0004] At present, the prevention and control methods of the wood borer of sea-buckthorn include physical control, chemical control, biological control, sex pheromone and forest management measures. The physical control refers to using black light lamp to kill the adults in the adult occurrence period; the chemical control can use dry base spraying, root irrigation, excrement hole injection and fumigation; the biological control refers to protecting and utilizing the natural enemy resources such as mites, parasitic wasps and small bees; the sex pheromone lure core is used to kill male adults in the adult period, which can effectively control the damage; the forest management measures adopt the block mixed planting method of sea-buckthorn and local tree species, and breed insect-resistant varieties. However, for sea-buckthorn fruits, they are basically organic products, and are not suitable for chemical control; the existing forest management measures have poor effect, and need to be combined with other control measures to achieve a certain effect; the physical control, biological control and sex pheromone have high labor or price cost. Moreover, the existing technology has very limited control ability on the wood borer of sea-buckthorn, because the wood borer of sea-buckthorn has very strong reproductive capacity after the adult stage, as long as a certain amount of wood borer of sea-buckthorn exists, a large number of wood borers of sea-buckthorn can be reproduced rapidly, which can cause devastating damage to sea-buckthorn. Therefore, it is urgent to develop a method for effectively preventing and controlling the wood borer of sea-buckthorn to improve the survival rate of sea-buckthorn trees. SUMMARY

[0005] In order to solve the above problems, the present application provides a sea-buckthorn planting method for preventing and treating diseases and pests, which can effectively prevent and treat the sea-buckthorn wood borer by mixed planting of sea-buckthorn and lilac and the cooperation of induced hormones, has low comprehensive cost, and has high survival rate, high yield and stable product quality.

[0006] To solve the above technical problems, the technical solution provided by the present application is:

[0007] A sea-buckthorn planting method for preventing and treating diseases and pests, wherein sea-buckthorn trees and lilac trees are planted at intervals, and sex-induced hormones are placed in the planting area from May to July every year to make male and female sea-buckthorn wood borer adults unable to distinguish each other.

[0008] Compared with the prior art, the sea-buckthorn planting method for preventing and treating diseases and pests provided by the present application takes full advantage of the volatile odor of lilac to interfere with the sea-buckthorn wood borer according to the characteristics that the sea-buckthorn wood borer (which has poor vision) searches by relying on olfaction, so that the sea-buckthorn wood borer cannot accurately find the sea-buckthorn trees, and thus cannot bore into the sea-buckthorn trees, thereby improving the survival rate of sea-buckthorn; the present application takes advantage of the habit that the mature larvae of the sea-buckthorn wood borer crawl out of the boring holes into the soil to pupate in May to June, and the adults emerge and mate to lay eggs in June to July, and places sex-induced hormones in the planting area from May to July every year to make male and female sea-buckthorn wood borer adults unable to distinguish each other, and thus unable to complete mating and egg laying, thereby greatly reducing the reproductive amount of the sea-buckthorn wood borer and achieving the purpose of further preventing and treating the sea-buckthorn wood borer. The present application can effectively prevent and treat the sea-buckthorn wood borer by mixed planting of sea-buckthorn and lilac and the cooperation of induced hormones, and can also avoid the use of chemical agricultural chemicals, reduce pollution, protect the environment, and reduce the comprehensive cost, greatly improve the survival rate of sea-buckthorn, and thus improve the yield and quality of sea-buckthorn fruit, and has high practical value and popularization value.

[0009] The inventor found through a large number of experiments that the sea-buckthorn wood borer has poor vision and mainly relies on olfaction to find the host; among a large number of tree species, only mixed planting of lilac and sea-buckthorn can effectively interfere with the olfaction of the sea-buckthorn wood borer, so that it cannot accurately find the sea-buckthorn trees, and thus cannot parasitize on the sea-buckthorn trees. For a small amount of sea-buckthorn wood borer larvae that have already parasitized in the crevices of the sea-buckthorn bark or the roots, the present application uses sex-induced hormones to make male and female sea-buckthorn wood borer adults in the mating period unable to distinguish each other, so that the purpose of reducing the reproductive amount of the sea-buckthorn wood borer can be achieved without killing the adults, and the efficiency of preventing and treating the sea-buckthorn wood borer is better than that of the prior art (using wood borer sex pheromone lures to kill male adults).

[0010] Preferably, the interval planting mode comprises: dividing the planting area into multiple rows, taking every 2 rows as 1 repetition to form a plurality of planting units; in each planting unit, one row is a sea-buckthorn tree unit, and the other row is an alternating planting unit of a single sea-buckthorn tree and a single lilac tree.

[0011] Further preferably, the distance between two adjacent trees in the row is 1.5-2.5 m, and the row spacing of the row is 3-6 m.

[0012] The present application can ensure the prevention of the wood-boring moth of Hippophae rhamnoides on the basis of not affecting the ventilation and lighting conditions of the Hippophae rhamnoides and Syringa oblata, thereby being beneficial to the growth of the Hippophae rhamnoides and Syringa oblata by controlling the distance between adjacent trees.

[0013] Preferably, the number of the Hippophae rhamnoides and the Syringa oblata in each mu of land is (2-3):1.

[0014] Preferably, the step of planting at intervals comprises seedling raising and transplanting.

[0015] Illustratively, the seedling raising and the transplanting are performed in spring.

[0016] Further preferably, the seedling-raised Hippophae rhamnoides seedlings have a root arm diameter of ≥0.5 cm and a height of 60-85 cm.

[0017] Further preferably, the seedling-raised Syringa oblata seedlings have a height of 35-50 cm.

[0018] Further preferably, the transplanting comprises 1-2 Hippophae rhamnoides seedlings per hole and 2-3 Syringa oblata seedlings per hole.

[0019] It should be noted that the Hippophae rhamnoides seedlings are divided into two types of sowing seedlings and cutting seedlings, and the number of seedlings per hole is 2 when the Hippophae rhamnoides seedlings are sowing seedlings, and the number of seedlings per hole is 1 when the Hippophae rhamnoides seedlings are cutting seedlings.

[0020] Further preferably, the depth of the hole for transplanting is 48-52 cm, and the diameter of the hole for transplanting is 43-47 cm.

[0021] Preferably, the main components of the sex-inducing hormone comprise the following components in parts by weight: cis-7-tetradecenyl alcohol acetate 30-40 parts, trans-7-tetradecenyl alcohol acetate 20-30 parts, cis-9-tetradecenyl alcohol acetate 15-20 parts, trans-5-tetradecenyl alcohol acetate 10-15 parts, cis-5-trans-3-tetradecenyl alcohol acetate 8-12 parts, cis-7-tetradecenyl alcohol 5-10 parts, and trans-3-tetradecenyl alcohol 2-5 parts.

[0022] The preferred sex-inducing hormone of the present application has volatility, and effective action time can reach 2-4 months, can make the female and male Hippopsichia arbutocovora adults in mating period unable to distinguish the opposite party, and the purpose of reducing the reproduction amount of Hippopsichia arbutocovora can be achieved without killing the adults, and the efficiency of preventing and treating Hippopsichia arbutocovora is superior to the prior art (using woodworm sex pheromone lure core to kill male adults). In the prior art, the male adults may have completed the copulation with the female adults before being lured and killed, and in the present application, as long as the female and male adults are within the volatile range of the sex-inducing hormone, they cannot distinguish the female and male adults, and thus cannot complete the copulation and reproduce offspring.

[0023] The inventor finds through a large number of experiments that when the sex-inducing hormone contains the above-mentioned specific proportion of seven C14 straight-chain alkenyl acetates and C14 straight-chain alkenols, the Hippopsichia arbutocovora adults are almost completely unable to distinguish the female and male adults, and the inhibition effect on the mating and reproduction of the female and male adults is the strongest. If any component is removed or the cis-trans structure is replaced, the inhibition effect on the mating and reproduction of the female and male adults will be reduced to different degrees; if the above-mentioned mass proportion is changed, the amount of a certain component is increased or decreased, the inhibition effect on the mating and reproduction of the female and male adults will also be reduced to different degrees.

[0024] It should be noted that the sex-inducing hormone in the present application is in paste form, and contains a certain amount of organic solvents and auxiliaries (such as antioxidants) in addition to the main components. The present application does not require the composition and amount of the organic solvents and auxiliaries, and the existing types of organic solvents and auxiliaries can be used, and the corresponding amount can be adjusted according to actual needs.

[0025] Preferably, the placement mode of the sex-inducing hormone is hanging, and the straight-line distance between the hanging point and the nearest Hippophae rhamnoides root is 5-8 m.

[0026] The present application can ensure that the Hippophae rhamnoides is within the effective volatile range of the sex-inducing hormone while ensuring that the Hippophae rhamnoides is not contaminated by chemical reagents by controlling the distance between the hanging point and the nearest Hippophae rhamnoides root.

[0027] For example, the hanging point is a wood board with a specification of 20 cm*15 cm, and the sex-inducing hormone is coated on the surface of the hanging point.

[0028] Further preferably, the number of the hanging points is 2-3 per mu.

[0029] The attracting distance of the female moth to the male moth can reach 1200 m, and the present application can reduce the amount of the sex-inducing hormone and save costs on the basis of ensuring the function of the sex-inducing hormone by limiting the number of the hanging points.

[0065] Comparative example 6

[0066] The comparative example provides a seabuckthorn planting method for preventing and treating pests and diseases, which is different from example 2 only in that it includes (1) planting seabuckthorn trees and lilac trees in intervals, but does not include (2) hanging sex pheromone.

[0067] Comparative example 7

[0068] The comparative example provides a seabuckthorn planting method for preventing and treating pests and diseases, which is different from example 2 only in that it does not use mixed planting, i.e., only seabuckthorn trees are planted.

[0069] (1) Seabuckthorn tree planting.

[0074] Effect example

[0075] In a certain factory area in Inner Mongolia, a suitable planting area is selected, and the seabuckthorn planting methods of examples 1-3 and comparative examples 1-7 are used for planting. The planting area of each planting method is basically square, and the area of the planting area is 3 mu. The number of seabuckthorn woodborers is detected from June 30, 2023 to July 6, 2023. The monitoring method includes: placing 5 insect sex pheromone traps (purchased from Beijing Jinyirun Technology Co., Ltd.) containing seabuckthorn woodborers in each planting area, each trap can detect 1 mu of land, and 5 traps are respectively located at the northwest corner, northeast corner, southeast corner, southwest corner and central position of the planting area.

[0077]

[0078]

[0079]

[0080] As can be seen from the above table, by using the sandthorn planting method for preventing and treating pests and diseases provided in embodiments 1-3, there are only 2-3 wood borers in a 3-mu planting area, which shows that by mixed planting of sandthorn and lilac and cooperating induction hormone, the wood borer of sandthorn can be effectively prevented and treated. Compared with the embodiments, in comparative examples 1-5, other tree species are mixed with sandthorn, and the number of sandthorn wood borers in a 3-mu planting area is 54-91, which shows that by planting sandthorn trees and lilac trees at intervals, the volatile odor of lilac can be fully utilized to interfere with the sandthorn wood borer, so that it cannot accurately find the sandthorn tree. Compared with the embodiments, in comparative example 6, only sandthorn trees and lilac trees are planted at intervals, and no induction hormone is hung to assist in preventing and treating the sandthorn wood borer, and there are still 38 sandthorn wood borers in a 3-mu planting area, which cannot effectively prevent and treat the sandthorn wood borer. Compared with the embodiments, in comparative example 7, only induction hormone is hung, and the mixed planting method of sandthorn trees and lilac trees is not used, and there are still 103 sandthorn wood borers in a 3-mu planting area, which still cannot effectively prevent and treat the sandthorn wood borer.

[0081] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
