Dichondra is creeping on the ground, coupled with its broad leaves, fertilization is more difficult, inappropriate methods are easy to burn seedlings. Let's take a look at the fertilization methods of Dichondra repens.

Introduction of Dichondra repens

Dichondra repens alias small money grass, lotus bract grass, meat wonton grass, gold key, copper money grass, small Dichondra, jaundice grass, is the spiral flower family, horseshoe metal plant. Distributed in the south of the Yangtze River in China (including Taiwan), widely distributed in Guizhou, Guangxi, Fujian, Sichuan, Zhejiang, Hunan and other places, growing in areas ranging from 1300 meters to 1980 meters above sea level, and growing on roadsides, hillside grasslands or ditches. Has been artificially introduced and cultivated. Dichondra repens is a common herbal medicine used by Miao people to treat hepatitis. The name of Miao medicine is "Wobi credit slip". It is a perennial creeping herb, harvested from April to June. Taste bitter, pungent, slightly cold, the host lung meridian and stomach meridian, with heat-clearing and detoxification, diuresis, blood-activating effect, is blindly rich in resources of Miao folk medicine, has a good development and utilization value. Herbal Dichondra, also known as small money grass, indications: heat-clearing; dampness; detoxification. For jaundice; dysentery; sand shower; white turbid; edema; eczema; fall injury; venomous snake bite.

Fertilization method of Dichondra repens

Dichondra likes nitrogen fertilizer, usually can be combined with watering and rain, apply the right amount of nitrogen fertilizer, it is best to apply urea about 3-5 kg per mu and 5-10 kg per mu of diammonium. After general turf cultivation for 3 years, the rhizomes are easy to gather together, which often causes soil consolidation, which is not conducive to air permeability and water seepage. At this time, we can pierce the hole according to the specific situation, or take the method of using a knife to cut off the grass root. In order to improve the looseness of the soil, at the same time apply appropriate amount of nitrogen fertilizer, appropriate amount of watering, so that it can recover as soon as possible.

Matters needing attention in fertilization of Dichondra repens

Usually before applying fertilizer to Dichondra, if you use a fertilizer with high solubility, you need to dissolve the fertilizer first, and then use spray to fertilize it. If you are using fertilizer that cannot be dissolved immediately, after applying it, you need to pour a lot of water and rinse the fertilizer on the leaves into the soil with water to dissolve it as soon as possible to reduce the degree of burns. or after fertilization, gently sweep the fertilizer under the leaves with a broom, and then combine with watering. And avoid fertilizing in hot weather.

Culture methods and matters needing attention of Dichondra repens

Dichondra repens is a perennial creeping herb, is a common folk medicine. Growing on roadsides, hillsides, grasslands or ditches, it has been introduced and cultivated artificially.

Culture methods of Dichondra repens: light and temperature

The growth of Dichondra should maintain enough light and be exposed to more sunlight every day so that it can grow exuberant and green. Dichondra repens has both light-loving and shade-resistant growth habits. It can grow in semi-humid places and does not require high temperature, but it will frostbite when the temperature drops from-6 ℃ to-7 ℃.

Water and fertilizer management

Dichondra repens needs regular irrigation and appropriate fertilization during its growth. The seedlings of Dichondra repens were irrigated once or twice a week after being unearthed, and the times of irrigation should be increased in dry season. After maturity, watering should be controlled in early spring and early winter, and the watering times should be determined according to the soil quality in the Spring Festival growing season.

Dichondra likes nitrogen fertilizer, usually combined with rain and watering, should apply appropriate amount of nitrogen fertilizer, after fertilization to pour a lot of water to reduce the degree of leaf burns. Or fertilize first, then sweep the fertilizer under the leaves, and then combine with watering. At the same time, the high temperature in summer can not be fertilized.

Soil

Dichondra is not very strict on the soil, as long as the drainage conditions are moderate, it can be planted on sandy soil and clay.

Grow in fields or mountains with fertile soil.

Matters needing attention in the culture of Dichondra repens to remove weeds

Dichondra repens in lawn greening, because it takes a period of time to fully cover, so there will be weeds, less weeds can be used to pull out manually, if more weeds can be used herbicide spray.

Propagation methods of Dichondra repens

Dichondra repens is commonly used to reproduce by sowing and dividing plants.

Pest control of Dichondra repens

Dichondra repens lawn has strong disease resistance, only white silk disease and a small amount of leaf spot mildew occur. Rust will also occur.

Sclerotinia disease.

The larval grubs of beetles, armyworm of night moths and larvae of small land tiger are the main pests of Dichondra lawn. There are other pests such as snails, meadow borer, and pointed locusts.

How to raise the waterfall effect of Dichondra

When raising Dichondra, light is very important. What Dichondra needs is an environment with sufficient light, sufficient light and good ventilation, so that Dichondra can grow well, branches and leaves are luxuriant, and Dichondra cultivated in hanging basins will have the effect of waterfall. When you need to pay attention, Dichondra needs proper shade in summer.

Watering and fertilization of Dichondra repens

Watering is the key to the good growth of Dichondra. Dichondra is a plant with relatively fine root system, which is not very resistant to drought. It is necessary to keep the soil moist when raising Dichondra. In general, when raising Dichondra, it needs reasonable watering and often sprays water on the plants of Dichondra. Be careful not to lack water, which will lead to the loss of leaves and sparse branches and leaves of Dichondra repens, which will affect how to cultivate Dichondra repens to produce waterfalls.

Fertilization is also a very important step. Dichondra prefers nitrogen fertilizer. If there is enough fertilizer, the branches and leaves will grow more luxuriantly, and it is easier to create a hanging basin with waterfall effect.

When raising Dichondra repens, nitrogen fertilizer can be applied in combination with watering, but do not pollute the leaves.

Pruning of Dichondra repens

Hanging basin culture of Dichondra to cultivate the effect of a waterfall, it is also very important to trim Dichondra how to cultivate a waterfall effect flower encyclopedia. The growth rate of Dichondra is still relatively fast, but in breeding, proper pruning can make its branches and leaves many and dense. And pruning can cut off the ornamental leaves in time, and sort out the branches that grow in disorder. In this way, you can create a beautiful waterfall and maintain its good shape.

Disease control of Dichondra repens

The disease control ability of Dichondra repens lawn is strong, only white silk disease and a small amount of leaf spot mildew occur. Most of the above diseases occurred in the high temperature and high humidity season from July to August. Spraying chlorothalonil and carbendazim once every 7 to 10 days can effectively control the occurrence and development of diseases. The main symptom of rust is to produce reddish-brown powdery sores or stripes on stems and leaves, and then turn dark brown. Generally, the spores of rust began to spread in April, first appeared on the leaves, and expanded to the whole plant in summer. In severe cases, the lawn withered and a large area died. The first control method is to avoid the application of nitrogen fertilizer in summer, and the second is to use chemical methods to control it. You can use 20% triadimefon EC, 30 to 40 milliliters per mu, or 40% carbendazim gel suspension, 75 to 100 milliliters per mu. The main symptoms of the damaged plants of Sclerotinia sclerotiorum are round brown or light brown spots, which become large disease spots with the deepening of the disease, especially the high temperature and humidity in summer, or improper application of nitrogen fertilizer, will aggravate the disease and cause large areas of alopecia areata on the lawn. First of all, when the disease occurs, the plants in the affected area are dug up and treated centrally with 5 cm soil layer, and 40% pentachloronitrobenzene powder is used to disinfect and sterilize the soil according to 2 grams per square meter. Secondly, pay attention to rainy season drainage, when the disease is serious, you can use 75% chlorothalonil wettable powder, the dosage is 100 to 125 grams per mu. The leaves, stems and roots of Baijuan disease can be damaged. The damaged leaves showed irregular yellow spots, and in severe cases, the whole leaves withered and wilted. The white silky mycelium and sclerotia with a diameter of about 1 mm could be seen at the base of the seriously damaged stem and near the soil surface. the sclerotia was white at first and then turned yellow and brown. The damaged yellow Dichondra lawn initially showed a circle of tens of centimeters in diameter, and with the development of the disease, it could be expanded into irregular hay circles of several meters. Sclerotia is the main source of primary infection of this disease. Sclerotinia sclerotiorum is a kind of soil resident bacteria, and the hyphae can spread widely in the soil and become the source of secondary infection. The disease was caused by high temperature (25 ℃-35 ℃) and high humidity. In addition, the rich organic matter in the soil was also beneficial to the occurrence of the disease. The medicament control can choose 1000 times solution of 1% chlorhexidine or 2000-2500 times liquid spray of 25% imipramine. The main pests of Dichondra lawn are the larvae of beetles, grubs, armyworm of night moths, and larvae of small land tiger. The leaves of Dichondra repens are relatively tender, the juice content is high, and they are seriously damaged by armyworm. In the emergence period of adults, the phototaxis and chemotaxis of adults were used to trap and kill with black light, poison bait and poisonous weeds to reduce their fecundity. The grub was sprayed with 1000 times of phoxim in the evening, and the larvae of armyworm and small land tiger were sprayed with 1000 times of omethoate, especially again the next day after spraying. The effect is the best, and insecticides such as phoxim and Lesbon can also be considered. There is also a kind of creature that harms Dichondra is a snail, which can be used alternately with Mida, Mihanluo and so on. The meadow borer does serious damage to the lawn. It eats the root and stem of the grass, interrupts the water supply of the plant, yellowes the stem and leaves until it dies. The prevention and control methods can be killed by black light, trapped by sugar and vinegar, and sprayed with 1000 times of Lesbon. The chewing leaves and tender stems of the pointed negative locust were eaten when they were serious, and the damage was the most serious from June to August. The method of control is to spray 0.5 kg of trichlorfon or dichlorvos with 500 kg of water per mu, or you can concentrate manpower to kill it in the morning. The small land tiger specializes in eating young stems and leaves, so that the lawn can not grow normally, and in serious cases, it can cause plant death. The control method uses 50% Dianong EC, 50 to 100 milliliters per mu, or 25% carbaryl wettable powder, 200 to 250 grams per mu.

The key point for the conservation of ground cover plant Dichondra repens Dichondra repens Forst, alias small money grass, lotus bract, meat wonton grass, gold key, copper money grass, small calla, jaundice grass, is the spiral flower family, horseshoe metal plant. The blade looks like a horseshoe, so it's easy to remember it. Most of them are planted under sparse forests, by the side of the road or by the pool, and can also be watched in pots. Habits: like warm, humid climate, not only strong adaptability, competitiveness and invasiveness, exuberant vitality, but also has a certain ability to withstand tread. Dichondra has the growth habit of both light and shade resistance, and has strong disease resistance and anti-pollution ability. Key points of conservation: as Dichondra creeping on the ground, and the leaves are relatively broad, it is difficult to apply fertilizer. If we do not strictly grasp the fertilization technology, it will cause serious seedling burning. Generally speaking, if you use fertilizers with high solubility, it is best to dissolve them first and then spray them with a sprayer; if you use fertilizers that cannot be dissolved immediately, you should pour a lot of water after fertilizing, flushing the fertilizers that fall on the leaves into the soil and dissolving them as soon as possible, so as to reduce the degree of burns; or apply fertilizer first, then sweep the fertilizer under the leaves with a broom, and then combine with watering. At the same time, high temperature fertilization should be avoided. Weeding: artificial weeding can be used when there are fewer weeds, and herbicides can be used if there are more weeds. Spraying green bacteria SL- 2 compound 525-675g/hm2 at one time could control the harm of most weeds and lasted for 80-90 days, and it was safe to Dichondra repens lawn. It is worth noting that herbicides are best used in weed seedling stage.
