Description

Method for regulating and controlling plant types of gloriosa lily based on plant growth regulator
Technical Field
The invention belongs to the field of flower cultivation, and particularly relates to a gloriosa lily plant type regulation and control method based on a plant growth regulator.
Background
The gloriosa lily, also known as flame lily, is a perennial climbing herb flower of gloriosa in the family of lily. The lily of the gloriosa has long flowering phase, and the flowers She Ju are beautiful, can be placed indoors for a long time, and have higher ornamental value and market development prospect. At present, in European and American countries, the lily bulb of the gloriosa is commercially produced as a high-grade cut flower and a high-grade potted flower, and in recent years, the lily bulb of the gloriosa is introduced into China as a fresh cut flower.
However, domestic gloriosa is often not good in plant height, internode and leaf number control, so that the internode is long, and production management, harvesting, transportation and bottle insertion are not facilitated. Therefore, the production of the gloriosa lily as a fresh cut peanut must solve the following 2 problems:
(1) Part of varieties of the gloriosa lily plants can reach more than 2 meters, and the gloriosa lily plants are not convenient for gardening operation and harvesting when being planted as fresh cut flowers.
(2) The plant has long internode, resulting in low flower branch hardness, insufficient uprightness, large small flower spacing, inconvenient transportation and bottle insertion, and reduced commodity value.
Therefore, in order to solve the above problems, it is required to control plant height, shorten stem length, facilitate gardening operations, harvest transportation, and improve cut flower quality using a growth regulator. However, the existing methods using growth regulators are less informative and do not form a unified standard. The traditional cultivation method mostly adopts a method of regularly spraying plant growth regulator, judges that the standard of the service time of the growth regulator is plant height, and lacks universality for varieties with different plant heights and flowering node positions according to the standard formulated by one variety.
If operated directly according to the conventional method, part of variety of gloriosa lily may be too early or too late due to the stopping of the spraying of the growth regulator, resulting in lengthening of the plant top internode or affected growth of small flowers, thus resulting in reduced commercial quality. Therefore, the prior method needs to be independently tested and adjusted for the starting treatment time of different varieties, and is inconvenient to manage.
In addition, some variety of the gloriosa lily with low flowering node and short plant height also needs to regulate and control the internode length, but the plant height is further reduced after regulation and control, only 1.2-1.5m can be achieved, only about 5-6 leaves are reserved for 50cm after harvesting, the leaves are less left in the period of growing the bulbs, the new bulbs grow slowly, and the cultivation of high-quality new bulbs is not facilitated.
Disclosure of Invention
In order to solve the technical problems, the invention discloses a gloriosa lily plant type regulation and control method based on a plant growth regulator, which improves the spraying nodes and the judgment standard of the traditional spraying method, can perform unified production management for different varieties, especially early-flowering varieties, and improves the working efficiency, the flower production and the ball production quality.
The technical scheme adopted in the invention is as follows:
a method for regulating and controlling the plant type of gloriosa lily based on a plant growth regulator comprises the following steps:
s1, when 1-2 leaves of the lily of the gloriosa are just spread and the plant height is 20-30cm, spraying a growth regulator for the first time;
s2, when the lily of the gloriosa is about to enter the flowering phase and lateral buds begin to appear on plant growing points, spraying a growth regulator for the second time;
and S3, when petals of the 1 st small bud of the gloriosa lily are about to be unfolded or just start to be unfolded, spraying the growth regulator for the third time.
Preferably, the growth regulator is a growth regulator having a function of inhibiting the elongation of the stalks.
Preferably, the active ingredient of the growth regulator is uniconazole, and the content of the active ingredient is 50-70mg/L.
Preferably, the foliar fertilizer is compounded when the growth regulator is sprayed every time, so as to strengthen the growth vigor and make the plants thicker.
Preferably, the ratio of the foliar fertilizer to water is 1:1000, the growth regulator is adjusted according to the content of the active ingredients and the water quantity.
Preferably, in step S1, the treatment mode of spraying the growth regulator for the first time may be further adjusted to perform root irrigation treatment with the growth regulator before the leaves of the lily bulb of the gloriosa are developed after budding.
Preferably, the amount of growth regulator sprayed per time is 1L/100 strain.
The beneficial effects are that: the invention provides a gloriosa lily plant type regulation and control method based on a plant growth regulator, which has the following advantages compared with the prior art:
(1) According to the invention, the application time of the growth regulator is determined according to the growth stage, and the judgment standard of the spraying time is changed from plant height to plant internode number and growth development stage, so that the regulation and control of the lily plant type of the gloriosa is more accurate, the uniform internode length of the flowering branch part can be ensured, and the method is applicable to varieties with different flowering time or node positions and is convenient for unified management.
(2) The invention shortens the internode at the lower part of the plant by applying the growth regulator in advance, changes the distribution of the stem nodes and the leaves of the plant, changes the concentration of the stem nodes at the upper middle part of the plant into the concentration at the upper part and the lower part of the plant, and ensures that more leafy growing balls can be left on branches with the same length after harvesting without affecting the harvesting quality, so that new seed balls grow faster and larger.
(3) The invention prolongs the interval between the first spraying and the second spraying of the growth regulator, so that the internode in the middle of the plant is longer, the phenomenon that the harvesting is affected by the too short plant height caused by the early application of the growth regulator is prevented, meanwhile, the plant is thicker by enhancing the growth vigor of the compounded foliar fertilizer, the stem hardness and the verticality of flowers are maintained, and the cut flower quality is ensured.
Detailed Description
In order to better understand the technical solutions in the present application, the following description will clearly and completely describe the technical solutions in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.
Example 1
In the example 1, the sprayed growth regulator is 830 times of 5% uniconazole wettable powder (namely, the content of the effective components is 50-70 mg/L), and the spraying amount of the compound foliar fertilizer (the commercial fertilizer with the content of nitrogen, phosphorus and potassium being 20-20) is 100 plants per 1 liter.
Experiment group 1: planting the gloriosa lily (variety A) in 2023 in 3 months and 20 days, sprouting in 4 months and 4 days, spreading out second leaves in 4 months and 10 days, performing first spraying, performing second spraying when the plant height reaches 70cm in 24 months and the growth point starts to appear in 27 days in 4 months, starting to open the flower bud of the 1 st floret in 5 months and 7 days, performing third spraying, starting to collect in 19 months, collecting the flower petals of the second floret in 5 months, keeping the lower part of the plant to be 50-70cm according to the variety, and collecting the bulbs in 7 months and 10 days.
Control group 1: planting the lily bulb of gloriosa (variety A) in 2023 in 3 months and 20 days, sprouting in 4 months and 4 days, spreading out second leaves in 4 months and 10 days, carrying out first spraying on the lily bulb of gloriosa until the plant height reaches 70cm in 4 months and 20 days, beginning to generate lateral buds at the growing point in 4 months and 27 days, carrying out second spraying on the lily bulb of gloriosa in 5 months and 2 days, beginning to open the flower bud of the gloriosa in 5 months and 7 days, canceling third spraying on the flower bud of gloriosa in 5 months and 12 days, beginning to collect in 5 months and 19 days, wherein the collection standard is that petals of the second gloriosa are flattened, the lower part of the plant is reserved according to the variety, 50-70cm is reserved, and the bulbs are collected in 7 months and 10 days.
Table 1 table of plant growth obtained from two different spray schemes
Note that: after harvesting, the plants in the ball-raising period remain for 50 cm.
From table 1, it can be seen that the thickness of the stalks obtained in the experimental group 1 for performing growth regulation by using the growth regulator spraying scheme of the present application is equivalent to that of the traditional scheme (control group 1), the plant height is slightly low, leaves remain more after harvesting, and new seed balls are larger. In addition, the control group adopting the traditional method has too long top internodes and reduced ornamental flowers due to too early time of last spraying of the growth regulator.
Example 2
In the example 2, the sprayed growth regulator is 830 times of 5% uniconazole wettable powder (namely, the content of the effective component is 70 mg/L), and the spraying amount of the compound foliar fertilizer (the commercial fertilizer with the content of nitrogen, phosphorus and potassium being 20-20) is 100 plants per 1 liter. The fertilizer sprayed in example 2 was the same as in example 1.
Experiment group 2: planting gloriosa lily (variety B) in 2023, 3-month 20-day planting, 4-month 4-day budding, 4-month 10-day spreading a second leaf, performing first spraying, wherein the plant height of 4-month 22 reaches 70cm, the growth point of 4-month 29 begins to generate lateral buds, performing second spraying, the flower bud of 5-month 10-day 1 st floret begins to open, performing third spraying, harvesting in 5-month 21-day, wherein the harvesting standard is that the petals of the second floret are flattened, keeping the lower part of the plant 50-70cm according to the variety, and harvesting balls in 7-month 10.
Control group 2: planting the gloriosa lily (variety B) in 2023 in 3 months and 20 days, sprouting in 4 months and 4 days, spreading out second leaves in 4 months and 10 days, spraying for the first time, spraying lateral buds at the growth point of 4 months and 29 days, spraying for the second time, opening the flower buds of 1 st flower in 5 months and 10 days, spraying for the third time, harvesting in 5 months and 21 days, wherein the harvesting standard is flattening of petals of the second flower, keeping the lower part of the plant 50-70cm according to the variety, and harvesting balls in 7 months and 10 days.
Table 2 table of plant growth obtained from two different spray schemes
Note that: after harvesting, the plants in the ball-raising period remain for 50 cm.
As can be seen from table 2, the plant height and the stem thickness obtained in the experimental group 2 for performing growth regulation by using the growth regulator spraying scheme of the present application are not different from those of the conventional scheme (control group 2), and leaves are more reserved after harvesting, and new seed balls are larger.
In the present invention, the initial unfolding of the small flower buds means that the petals growing together become easily visible 1-2 mm apart.
In the invention, the first spraying of the growth regulator can be changed into root irrigation before leaf expansion after budding, which is beneficial to improving the leaf density. But also consider the effect of root irrigation on root growth.
In the invention, the formula of the growth regulator can be modified and replaced by other growth regulators for inhibiting the elongation of the stems, and the dosage is correspondingly modified by a person skilled in the art according to actual requirements.
The formulated foliar fertilizer of the invention can be modified according to the actual growth conditions by the person skilled in the art, and the compounding proportion is correspondingly modified.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
