Description

Technical Field

[0001] The invention relates to the technical field of Podocarpus cultivation, and in particular to a composition for inhibiting the growth of Podocarpus fruit and protecting branches and leaves and an application thereof. Background Art

[0002] Podocarpus, also known as Tushan, is an evergreen coniferous tree of the Podocarpaceae family and Podocarpus genus, up to 20 meters tall and with a breast diameter of 60 centimeters; the bark is gray or gray-brown, shallowly cracked longitudinally, and falls off in thin flakes; the branches are spread or obliquely spread, and are dense. The leaves are spirally arranged, linear-lanceolate, and slightly curved. The male cones are spike-shaped and axillary, with several triangular bracts at the base; the female cones are solitary in the leaf axils, with stalks, and a few bracts at the base. The seeds are oval, with rounded tips, and the fleshy aril is purple-black with white powder when ripe. The seed receptacle is fleshy and cylindrical, red or purple-red. The flowering period is April to May, and the seeds mature in August to September. Podocarpus can be potted indoors or used as a flowerbed flower, with extremely high ornamental value.

[0003] However, many female Podocarpus trees have a large number of fruits, which consume nutrients from the tree and affect the growth of the plant. After bearing a lot of fruits, the fruits consume a lot of nutrients after a certain period of growth, which often causes the branches and leaves to turn yellow or even dry up, which is not conducive to the normal growth of the plant and also affects the ornamental effect. Therefore, in many planting nurseries and maintenance, the fruit-bearing Podocarpus will be picked, but there are many negative effects of picking: some Podocarpus trees are tall and large, and manual picking requires a long time of high-altitude work, which poses a great safety risk, and many workers are relatively old, which increases the safety risk; workers are difficult to find, and the cost of manual picking is high; the efficiency of picking is low, and the branches and leaves will be damaged during the picking process, and some tender branches and leaves will be removed, affecting growth. Summary of the invention

[0004] In order to solve the defects in the prior art, the present invention provides a composition and application for inhibiting the growth of Podocarpus carpio and protecting branches and leaves, so as to inhibit the growth of Podocarpus carpio, promote the shedding of Podocarpus carpio, and reduce the number of swollen Podocarpus carpio, thereby achieving the purpose of reducing the nutrient consumption of Podocarpus carpio on the tree body, and can also protect the tender branches and buds of the fruit tree, and solve the cost and safety problems caused by artificial labor.

[0005] To achieve the above object, the present invention adopts the following technical solution:

[0006] In a first aspect, the present invention provides a composition for inhibiting the growth of Podocarpus cones and protecting branches and leaves, comprising the following active ingredients: ethephon, aminoethyl hexanoate, benzylamine·gibberellic acid, amino acid water-soluble fertilizer and macronutrient fertilizer, wherein the mass ratio of the ethephon, aminoethyl hexanoate, benzylamine·gibberellic acid, amino acid water-soluble fertilizer and macronutrient fertilizer is (12-20): (1.2-2): (0.72-0.9): (1.2-1.8): (9-18).

[0007] Preferably, the mass ratio of ethephon, ammonium hexanoate, benzylamine and gibberellic acid, amino acid water-soluble fertilizer and macronutrient fertilizer is 20:2:0.72:1.2:9.

[0008] Preferably, the mass ratio of benzylamine to gibberellic acid in the benzylamine·gibberellic acid is 1:1.

[0009] Preferably, the amino acid water-soluble fertilizer contains amino acids ≥ 100 g / L and Cu+Fe+Zn ≥ 20 g / L.

[0010] Preferably, the macronutrient fertilizer contains a nitrogen source, a phosphorus source and a potassium source. In some embodiments of the present invention, the macronutrient fertilizer is obtained from N-P2O5-K2O (20-20-20) macronutrient water-soluble fertilizer, wherein the mass content of the macronutrient fertilizer is 60%.

[0011] The active ingredients in the composition of the present invention can be purchased through commercial channels for compounding, or the preparation containing the active ingredients can be purchased and directly compounded.

[0012] In a second aspect, the present invention provides a use of the above composition in inhibiting the growth of Podocarpus cones and protecting the normal growth of branches and leaves.

[0013] Preferably, the application includes uniformly mixing the components and preparing them into any one of emulsifiable concentrate, microemulsion, water emulsion, suspension, oil suspension, dry suspension, wettable powder or water dispersible granules with adjuvants permitted in pesticides.

[0014] Preferably, the application is to spray the composition on Podocarpus plants, preferably with a small amount of dripping after the whole plant is evenly sprayed, and the spraying amount is 72-120 g / mu of ethephon, 7.2-12 g / mu of ammonium ethyl hexanoate, 4.32-5.4 g / mu of benzylamine and gibberellic acid, 7.2-10.8 g / mu of amino acid water-soluble fertilizer and 54-108 g / mu of macronutrient fertilizer.

[0015] Preferably, the composition is sprayed during the young fruit stage of Podocarpus carpio (approximately from the end of March to the beginning and middle of April each year).

[0016] Preferably, the application is spraying the composition once a year.

[0017] The beneficial effects of the present invention are:

[0018] The invention compounds five active ingredients, namely, ethephon, aminoethyl hexanoate, benzylamine·gibberellic acid, amino acid water-soluble fertilizer and macronutrient fertilizer. The ingredients complement each other and work synergistically to jointly inhibit the growth of Podocarpus caryophyllus fruit, reduce the number of swollen Podocarpus fruit, promote the concentrated shedding of Podocarpus fruit, and reduce the consumption of tree nutrition by Podocarpus fruit, thereby protecting the tender branches and buds of the fruit tree. Among them, ethephon can effectively inhibit the growth of Podocarpus cones and promote the shedding of Podocarpus cones, but it can easily cause stimulation and influence on other organs such as branches and leaves; the addition of aminoethyl hexadecene can reduce the stimulation of ethephon on Podocarpus branches and leaves, reduce the shedding of Podocarpus leaves, and aminoethyl hexadecene itself can increase the content of chlorophyll to accelerate the photosynthesis rate, promote the division and elongation of plant cells, promote the development of root system, regulate the balance of nutrients in the body, enhance the plant's absorption of amino acid water-soluble fertilizer and macronutrient fertilizer, and promote fruit ripening; the addition of benzylamine and gibberellic acid can control vegetative growth, promote early ripening and shedding of fruits, and also reduce the influence of ethephon on leaves, and promote the normal growth of Podocarpus branches and leaves; amino acid water-soluble fertilizer is foliar fertilizer, which can provide plants with trace elements nutrients required for growth while reducing the influence of ethephon on leaves, ensuring the normal growth of branches and leaves; macronutrient fertilizer is foliar fertilizer, which can be quickly dissolved in water, and is more easily absorbed by Podocarpus plants, and its absorption and utilization rate is relatively high, which can provide plants with macronutrient nutrients required for plant growth and reduce the influence of ethephon on branches and leaves.

[0019] The composition of the invention is safe and easy to use during application, and can be directly sprayed to promote fruit shedding and protect tender branches and leaves of Podocarpus, thereby greatly reducing the cost of manual picking and being suitable for industrial production.

[0033]

[0034]

[0035] As can be seen from Table 2, 5 days after spraying the liquid medicine, the number of swollen fruits is still large, and the Podocarpus fruit is still basically growing, and a small amount of leaf falling has occurred at this time; 10-15 days after spraying, the number of fruits decreases, a small amount of fruits fall off, most of the fruits stop growing, the number of swollen fruits is small, and the number of fallen leaves increases to a certain extent; 20 days after spraying, most of the fruits fall off, leaving individual fruits to continue growing, and there are still a small amount of fallen leaves, and the buds have grown and matured at this time; 61 days after spraying, more new buds sprout again, the number of fallen leaves increases slightly, and the fruit drop rate reaches 97%, indicating that the composition of this embodiment can promote the shedding of Podocarpus fruit, inhibit the growth of Podocarpus fruit, reduce the number of swollen fruits of Podocarpus fruit, and protect the tender branches and buds of fruit trees.

[0036] Example 3

[0037] The active ingredients of the composition of this embodiment are: ethephon, ammonium hexanoate, benzylamine·gibberellic acid, amino acid water-soluble fertilizer and macronutrient fertilizer in a mass ratio of 16:1.6:0.81:1.5:13.5.

[0038] Preparation method: Mix 40g of ethephon with a mass concentration of 40%, 20g of aminoethyl hexanoate with a mass concentration of 8%, 22.5g of benzylamine·gibberellic acid with a mass concentration of 3.6%, 12.5ml of 120g / L amino acid water-soluble fertilizer, and 22.5g of N-P2O5-K2O (20-20-20) macro-element water-soluble fertilizer (the content of macro-element fertilizer is 60%), and add water to 15L, wherein the mass ratio of benzylamine to gibberellic acid in benzylamine·gibberellic acid is 1:1.

[0040] Table 3 Fruit and foliage conditions at different times after spraying the composition of Example 3

[0041]

[0042]

[0043] As can be seen from Table 3, 5 days after spraying the liquid medicine, the number of swollen fruits is still large, and the Podocarpus fruit is still basically growing, and a small amount of leaf falling has occurred at this time; 10-15 days after spraying, the number of fruits decreases, a small amount of fruits fall off, most of the fruits stop growing, the number of swollen fruits is small, and the number of fallen leaves increases to a certain extent; 20 days after spraying, most of the fruits fall off, leaving individual fruits to continue growing, and there are still a small amount of fallen leaves, and the buds have grown and matured at this time; 61 days after spraying, more new buds sprout again, the number of fallen leaves increases slightly, and the fruit drop rate is 95%, indicating that the composition of this embodiment can promote the shedding of Podocarpus fruit, inhibit the growth of Podocarpus fruit, reduce the number of swollen fruits of Podocarpus fruit, and protect the tender branches and buds of fruit trees.

[0044] Comparative Example 1

[0045] Same as Example 1, except that there is no ethephon in the composition.

[0046] The results of spraying the composition are shown in Table 4.

[0047] Table 4 Fruit and branch conditions at different times after spraying the composition of Comparative Example 1

[0048]

[0049]

[0050] As can be seen from Table 4, the treatment was during the germination and fruiting period of Podocarpus, during which the number of fruits increased slightly. However, if there was no ethephon in the composition, the fruit drop effect could not be achieved, a small amount of leaves fell, and it was difficult to germinate 61 days after spraying.

[0051] Comparative Example 2

[0052] The same as Example 1, except that the composition does not contain aminoethyl hexanoate and benzylamino gibberellic acid.

[0053] The results of spraying the composition are shown in Table 5.

[0054] Table 5 Fruit and branch conditions at different times after spraying the composition of Comparative Example 2

[0055]

[0056]

[0057] As can be seen from Table 5, if there is no aminoethyl ester and benzylamine·gibberellic acid in the composition, although the fruit drop rate is high after spraying, the number of fallen leaves is large and the number of late buds is small. That is, although the composition of Comparative Example 2 can promote the shedding of Podocarpus to a certain extent, it cannot protect the branches and leaves of the fruit trees.

[0058] Comparative Example 3

[0059] The same as Example 1, except that the composition does not contain amino acid water-soluble fertilizer and N-P2O5-K2O (20-20-20) macro-element water-soluble fertilizer.

[0060] The results of spraying the composition are shown in Table 6.

[0061] Table 6 Fruit and branch conditions at different times after spraying the composition of comparative example 3

[0062]

[0063]

[0064] It can be seen from Table 6 that if there is no amino acid water-soluble fertilizer and macronutrient fertilizer in the composition, although the fruit drop rate is high after spraying, the number of fallen leaves is large and the number of late buds is small. That is, although the composition of Comparative Example 3 can promote the shedding of Podocarpus to a certain extent, it cannot protect the branches and leaves of the fruit trees.

[0065] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention, and the protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
