Description

Technical Field

[0001] This invention belongs to the field of floriculture technology, specifically relating to an intelligent irrigation method for a multi-species cultivation model of understory flowers. Background Technology

[0002] Diverse cultivation of flowers under forest canopies not only makes full use of forest space and shaded environments but also beautifies the environment and improves economic benefits. Roses are perennial evergreen or semi-evergreen low shrubs belonging to the genus Rosa in the Rosaceae family. They come in a rich variety of colors and types and can be used as ornamental and medicinal plants. In rose cultivation, the application of different exogenous plant growth regulators or other compounds can promote plant growth and improve the quality and commercial value of cut roses. However, in practical applications, the effects of different exogenous plant growth regulators or other compounds on rose plants vary, sometimes significantly. The inventors discovered through experiments that irrigating the roots of roses with a mixture of fluoxetine-activated ester solution and hydroxyadenine solution can significantly improve the quality of cut roses, thereby increasing their commercial value and economic benefits. Currently, no related reports have been found.

[0003] Professor Yu Heng divided the phenological changes of flowering into 12 stages, including the budding stage, the small bell stage, the large bell stage, the round peach stage, the initial opening stage, the full bloom stage, and the withering stage. Among them, the budding stage is when the flower buds are 5-6 cm higher than the top of the young leaves, and the leaf arrangement on the flower stem is obvious, with the flower buds measuring about 1.8 × 0.8 cm in size; the small bell stage is when the sepals covering the flower buds begin to open outwards, forming a bell shape, with the flower buds measuring about 2 × 1.3 cm in size; the large bell stage is when all the outer sepals of the flower buds are open, and the flower buds enlarge to a round shape, measuring about 2.5 × 1.8 cm in size; the round peach stage is when the flower buds rapidly enlarge, resembling cotton bolls, with a slightly pointed tip, measuring about 3 × 2.8 cm in size.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent irrigation method for a diversified cultivation model of understory flowers, so as to solve the problems existing in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A smart irrigation method for a multi-species cultivation model of understory flowers includes the following steps: irrigating the roots with a growth promoter once a day during the budding stage of the flowers, and keeping the soil moist during the remaining time. The growth promoter is a mixture of fluazole activated ester solution and hydroxyadenine solution.

[0008] Preferably, the mass ratio of the fluazole-activated ester to hydroxyadenine is 1:4-5.

[0009] As a preferred method, the irrigation volume is 10-20 mL.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention relates to the irrigation of a growth promoter composed of a mixture of fluazole-activated ester and hydroxyadenine during the multi-varietal cultivation of flowers under forest cover. Experiments have shown that when the mass ratio of fluazole-activated ester to hydroxyadenine is 1:4-5, the mixture has a significant effect on the EC50 of rose pedicel length. 10 The EC50 concentrations were 0.9835 mg / L and 0.6912 mg / L, respectively, for the diameter of rose buds. 10 The EC50 values ​​were 0.8499 mg / L and 1.0276 mg / L, respectively, both significantly lower than those of fluoxetine activated ester or hydroxyenine adenine alone for the effects on rose pedicel length and bud diameter. 10 Value. This indicates that the growth promoter of the present invention can promote both the elongation of rose flower stalks and the increase in the diameter of rose buds at a low concentration. Compared with single components, it can reduce the amount of agent used, which helps to improve the quality and grade of cut roses and increase economic benefits. Detailed Implementation

[0012] The technical solution of this invention patent will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention.

[0016] 1.2 Test reagents

[0017] 98% fluazole activated ester, 98% hydroxyadenine

[0018] 1.3 Test Site

[0020] 1.4 Test Methods

[0021] The test reagent was dissolved in dimethyl sulfoxide and then diluted with water to 5000 mg / L as the stock solution; multiple ratios were set up, and the stock solution and the ratio mixture were diluted with water respectively to set up 5 mass concentration gradients.

[0022] The rose planting area was randomly divided into multiple plots. During the rosebud formation stage, the roots of each plot were irrigated daily with the aforementioned pesticide solution at a rate of 10 mL per plant. A control group was established by irrigating with an equal amount of water. Ten rose plants were randomly selected from each plot, and two flowers were randomly selected from each plant. These plants were labeled and numbered. Four plots were treated with each solution. The soil was kept moist for the remaining time. At peak bloom (when approximately 50% or more of the flowers are open), the length of the flower stalk (cm) and the diameter of the flower bud (cm) were measured for each treatment. Using the logarithm of the pesticide concentration as x and the probability of promotion rate as y, a regression analysis equation was established to calculate the EC50 for each pesticide. 10 (The probability value corresponding to 10% is 3.7184). The results are shown in Table 1 and Table 2.

[0023]

[0024] Table 1 Effects of the test reagents on pedicel length

[0025]

[0026] Table 1 shows that fluoxetine-activated ester has an effect on the EC50 of rose pedicel length. 10 The EC50 of hydroxyadenine on the length of rose pedicels was 6.3704 mg / L. 10 The concentration was 3.2593 mg / L; when fluoxetine and hydroxyadenine were mixed in a mass ratio of 1:1-7, and when the mass ratio was 1:3-6, the EC50 of the mixed combination on the length of rose pedicels was 3.2593 mg / L. 10 The concentrations ranged from 0.6912 to 2.8172 mg / L, all lower than the EC50 of hydroxyadenine on the effect of hydroxyadenine on the length of rose pedicels. 10 The value, especially when the mass ratio is 1:4-5, is significant for the EC value of rose pedicel length when using mixed combinations. 10 The concentrations of 0.9835 mg / L and 0.6912 mg / L indicate that the promoter of the present invention can promote the elongation of rose stalks at a lower concentration, thus reducing the amount of agent required.

[0027] Table 2 Effects of the tested reagents on flower bud diameter

[0028]

[0029] Table 2 shows that fluoxetine-activated ester has an effect on the EC50 of rose bud diameter. 10 The EC50 of hydroxyadenine on the diameter of rose buds was 9.4571 mg / L. 10 The concentration was 4.1937 mg / L; when fluoxetine-activated ester and hydroxyadenine were mixed in a mass ratio of 1:1-7, and when the mass ratio was 1:3-5, the EC50 of the mixed combination had an effect on the diameter of rose buds. 10 The concentrations ranged from 0.8499 to 1.2825 mg / L, all lower than the EC50 of hydroxyadenine on the diameter of rose buds. 10The value, especially when the mass ratio is 1:4-5, is significant for the EC value of rose bud diameter when using mixed combinations. 10 The concentrations were 0.8499 mg / L and 1.0276 mg / L, indicating that the promoter of the present invention can promote the diameter of rose buds at a low concentration, thus reducing the amount of agent required.

[0030] Based on Tables 1 and 2, when the mass ratio of fluoxetine activator to hydroxyadenine is 1:3-5, it can promote the elongation of rose pedicels and the increase in the diameter of rose buds at lower concentrations. Compared with single components, it can reduce the amount of pesticide used, which helps to improve the quality and grade of cut roses and increase economic benefits.
