The cultivation method of calfgrass

Dichondra repens has green leaves, low plants, dense and beautiful leaves, and is an excellent turf grass and ground cover greening plant. Let's take a look at the planting method of Dichondra repens.

The planting method of Dichondra repens

1. Soil preparation: loosen, rake and refine the ground so that the diameter of soil particles is less than 2cm. Adjust the soil pH to 5.5-7.0. Disinfect the soil with formalin: water = 1:40, the dosage is 1015L per square meter of bed. The soil needs to be dry before disinfection.

2. Trenching and transplanting: make a deep trench of 2~3cm on the prepared turf bed, and the distance between the trench and 3~4cm. Separate the prepared Dichondra plants and place them evenly in the ditch, keep the plant spacing 3~4cm, cover with soil 2cm, water once, cover with sunshade net or grass curtain, and keep the soil moist every day. On the 5th day of planting, the plant grew vigorously, but the stolons did not fully contact the ground and grow new roots; on the 10th day, a large number of stolons in full contact with the ground will grow new roots and buds.

3. Cultivation covered with fine sand: before planting, the prepared turf was watered thoroughly, the turf of Dichondra repens was torn off manually and spread evenly on the bed, and the prepared fine sand was evenly scattered on the top of Dichondra repens. The sand 6~10mm was thick, keeping the fine sand completely moist, and covered with sunshade net to prevent excessive evaporation of water. By the 5th day, a large number of new roots had grown on the stolon nodes of Dichondra repens, and on the 10th day, a large number of new branches had grown in the place where the new roots were born.

4. Fertilization: due to the creeping growth of Dichondra repens on the ground, and the leaves are relatively broad, fertilization is very difficult. 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.

Like nitrogen fertilizer, usually combined with rain and watering, should apply appropriate amount of nitrogen fertilizer, it is best to apply urea 3~5kg/ mu plus diammonium 5~10kg/ mu. After 2 or 3 years of turf cultivation, due to the dense rhizome, it is easy to cause soil consolidation to affect air permeability and water seepage. Piercing can be carried out according to the situation, or a knife can be used to cut off the grass root to improve the looseness of the soil, and nitrogen fertilizer and proper watering should be added at the same time to restore the vitality of the lawn.

5. Weed control: the number of weeds in Dichondra repens lawn is less than that in Dichondra, Manila and tall fescue lawn. This phenomenon is due to the strong creeping nature of Dichondra lawn. On the other hand, it is because of the long green period, anti-green and strong competitiveness of weeds. However, in the newly planted Dichondra lawn, it takes 2-3 months to fully cover the ground, so it is easy to be invaded by weeds before it is fully covered. Artificial extraction can be used when there are few 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.

The Medicinal value of Dichondra repens

The function of Dichondra repens is mainly for jaundice; dysentery; sand gonorrhea; white turbidity; edema; eczema; fall injury; venomous snake bite. Clearing heat and promoting dampness, detoxification and detumescence. For hepatitis, cholecystitis, dysentery, nephritis edema, urinary tract infection, urinary calculi, tonsillitis, fall injury, slightly bitter, sweet, cold. Enter the water, wind tower.

It can protect liver and lower enzyme, analgesia, anti-inflammation, antibacterial, antipyretic and cholagogic, enhance immunity and anticancer effect. As an adjunct to other drugs, Dichondra can treat "cattle", "Mengsha Hei", "answer from ear to ear", "bury people from ear to ear", and "say Feng Linglan" (these are all Miao languages, and the editor really doesn't understand the meaning. I can only ask my friends to search the Internet).

When taking it, you can take it internally, fry soup, take an appropriate amount of tamping and apply it to the affected area.
