Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garden plant cultivation, in particular to a leaf color regulation method of Philodendron plants. BACKGROUND

[0002] Philodendron plants are common indoor ornamental plants, which are characterized by long and thin stems and heart-shaped leaves.

[0003] Philodendron belongs to the Philodendron genus (Hedera genus) and is a semi-shady plant, which is originally from the tropical regions of the Americas. Its morphological characteristics include long air roots, the characteristic of climbing other things, and the diversity of leaf shape and color.

[0004] Specifically, the leaves of Philodendron vary in shape according to different varieties, such as round heart-shaped, long heart-shaped, oval triangular, pinnately lobed leaves, and palmately lobed leaves. The leaf color also varies, such as green, brown red, and golden yellow. Philodendron plants that bloom in adulthood are mainly for leaf observation. Such plants are green and lush in all seasons, have strong shade tolerance, are high-grade indoor plants, and can also root when the stems are inserted into water. The propagation methods include sowing, division, cutting, or high-pressure method, and the suitable period is from spring to summer. When propagating, the bushy and upright Philodendron can be propagated by male plants. The cutting method is the most practical for general propagation. The stem section is cut to 2-4 nodes, the lower leaf of the stem is removed, and then it is obliquely buried in the soil, keeping the humidity. After about 2-3 weeks, roots can be generated. When the lower leaves of the old plant fall off and it is difficult to grow new leaves, the high-pressure method can be used for seedling raising, and then the new plant can be replanted. The growth environment of Philodendron requires humus soil with good ventilation. It needs appropriate diffuse light during growth and cannot be exposed to the sun. If the light is too strong, the leaf surface will easily dry out and the leaf edges and tips will be easily burned. Philodendron grows well in a warm and humid semi-shady environment, and the suitable growth temperature is 16-26℃. It is afraid of severe cold and dislikes strong light.

[0005] The contradiction between the increasing demand for flower varieties and the limited actual varieties is prominent among flower lovers. However, it takes a long time to breed an ornamental variety, and the number of varieties that can meet the market is limited. SUMMARY

[0006] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present application is to provide a leaf color regulation method of Philodendron plants. Through the application of this technology, 3-4 new leaves of each pot of Philodendron plants change color after drug treatment, and the remaining old leaves still maintain the original color. The new leaves are surrounded by the surrounding old leaves, forming a variety with high ornamental value. The tolerance is also good, and the observation period can reach more than 4 months, also having good ornamental value. After years of research and development, good results have been achieved. The selling price of the original Philodendron plants is higher, and the economic benefit is better.

[0007] The purpose of the present application is achieved by the following technical solution: a leaf color regulation method of Philodendron plants, comprising the following steps:

[0008] (S1), taking the control agent A, and growing the Philodendron-like plant to the finished product character;

[0009] (S2), applying the control agent A to the leaves of the Philodendron-like plant growing to the finished product character, and then carrying out the interval dry and interval wet management and maintenance.

[0010] The leaf color control method of the Philodendron-like plant of the present application uses the above control method. First, the original production mode is not changed, and the control agent A is sprayed in the later stage on the basis of the original cultivation, which is easy to operate, low in cost, good in effect, and strong in implementability for the growers. Second, through the control agent A, the color of the middle several leaves can be changed, while the color of the surrounding old leaves is not greatly affected, and the two present a sharp contrast, improving the ornamental value and finally enriching the market and the variety of Philodendron-like plants. Third, through the implementation of the leaf color control method, the selling price of the finished product is increased by 30%-50%, and it is loved by consumers, so the sales volume is increased, the economic value of the Philodendron-like plant is effectively improved, and through the implementation of the leaf color control method, the sales volume and added value of the variety are increased, and the income of the growers is increased. Fourth, the leaf color control method provides a new method to change the variety, which is short in time and low in cost, and can achieve the effect of changing the leaf color without breeding.

[0011] Among them, the control agent A is applied to the Philodendron-like plant growing to the finished product character. If the finished product is too old, the color change effect is poor, and the ornamental value is reduced, and if the control agent A is applied before the finished product character, it is easy to damage the leaves of the plant and difficult to grow to the finished product character.

[0012] Preferably, in the step (S2), if the leaves of the Philodendron-like plant do not change color 5-7 days after the control agent A is applied, the control agent A is applied to the leaves again, and then the interval dry and interval wet management and maintenance are carried out.

[0013] By adopting the above technical solution, the effective color change of several leaves of the Philodendron-like plant is further ensured, and after the control agent A is applied, only the color of the middle several leaves is effectively changed, while the color of the surrounding old leaves is not greatly affected, and the two present a sharp contrast, which is more ornamental.

[0014] Preferably, the control agent A is mixed by water and isoxaben herbicide at a volume ratio of 2800-4500:1.

[0015] Further, in the step (S2), the application amount of the control agent A applied to the leaves is 550-1050 plants per liter of Philodendron-like plants.

[0016] The above technical scheme controls the lower concentration and amount of the control agent A, so as to play a role on the new leaves and inhibit the synthesis of chlorophyll of the new leaves, and has little effect on the old leaves, and can avoid the death of the dieffenbachia caused by the control agent A; and the reasonable dilution multiple of the herbicide of the control agent A is beneficial to the color change effect of the leaves, if the dilution multiple is too high, the concentration of the herbicide of the control agent A is too low, the color change effect is not obvious, and even the same leaf appears half color change and half original color, and the ornamental effect is poor; and if the dilution multiple is too low, the concentration of the herbicide of the control agent A is too high, even if the color of the leaves is changed significantly after application, the ornamental period is significantly reduced and even the plant is easily dead, which affects the ornamental value.

[0017] Preferably, in the step (S2), if the leaves of the dieffenbachia are obviously changed in color 5-7 days after the application of the control agent A, the control agent B is taken, the control agent B is applied to the leaves, and then the interval dry and interval wet management and maintenance are performed.

[0018] The above technical scheme is beneficial to further maintain the color change ornamental effect and the ornamental period.

[0019] Preferably, the control agent B is mixed by water and the herbicide of the control agent A at a volume ratio of 7500-8500:1.

[0020] Further, in the step (S2), the application amount of the control agent B applied to the leaves is 550-1050 plants of the dieffenbachia per liter.

[0021] The above technical scheme controls the lower concentration and amount of the control agent B, which is beneficial to maintain the color change ornamental effect and the ornamental period of the dieffenbachia, and avoids the decrease of the tolerance of the plant and the shortening of the ornamental period caused by the death of the plant. Further, the effective component of the herbicide of the control agent A and the control agent B is 40%-50% of the herbicide of the control agent A, for example, the herbicide of the control agent A is selected from the herbicide of the control agent A available on the market.

[0022] Preferably, in the step (S2), at least one liquid fertilizer is applied during the maintenance, and the liquid fertilizer is mixed by phosphorus fertilizer, potassium fertilizer, nitrogen fertilizer and water at a weight ratio of 0.8-1:0.8-1.2:0.2-0.4:1000.

[0023] Further, the application amount of the liquid fertilizer is 500-800 milliliters per plant of the dieffenbachia.

[0024] Compared with the maintenance method before the control, the above technical scheme reduces the use of nitrogen fertilizer and increases the phosphorus and potassium fertilizer, which is beneficial to improve the toughness of the plant, prolong the duration of the color change leaves, and delay the ornamental period.

[0025] Preferably, the begonia plants include, but are not limited to, red diamond begonia, green princess begonia, heart leaf begonia, piano leaf begonia, velvet begonia, golden begonia, feathered begonia or fish leaf begonia.

[0026] More preferably, the begonia plants are red diamond begonia or green princess begonia; the green princess is widely used in the market, and has the advantages of dark green leaf color, thick and leathery leaves, good resistance to display, etc. Through the application of the technology, 3-4 new leaves of each pot of green princess are changed from green to white after drug treatment, and the remaining old leaves remain original green. The white color is surrounded by green, forming a variety with high ornamental value, good resistance to display, and an observation period of more than 4 months. The ordinary red diamond has a large market share, and 3-4 new leaves are changed to pure red after using the technical method, which also has good ornamental value and is deeply loved by flower lovers.

[0027] The begonia plant leaf color regulation method of the present application has the following advantages: 1. The method does not change the original production mode, and is easy to operate, low in cost and good in effect, and is highly implementable for growers based on the original cultivation; 2. The intermediate leaves can be changed in color by the drug A, while the surrounding old leaves are not much affected, which presents a sharp contrast and improves the ornamental value, and finally enriches the begonia plant varieties in the market; 3. The pot planting sales price of the product is increased by 30%-50% through the implementation of the leaf color regulation method, and is loved by consumers, thereby increasing the sales volume and effectively improving the economic value of the begonia plant; 4. The leaf color regulation method provides a new method to change the variety, which is short in time and low in cost, and can achieve the effect of changing the leaf color without breeding.

[0028] The begonia plant leaf color regulation method of the present application is suitable for original begonia pot planting enterprises and farmers, and is suitable for high-end and simple greenhouse planting, and has good cold resistance and wide variety adaptability.

[0029] The begonia plant leaf color regulation method of the present application belongs to the ecological and environmental protection technology, and is low in drug dosage, harmless and low in toxicity, and can reduce the drug dosage and increase the plant stress resistance.
