Introduction to cultivation techniques and Disease Control of Green Flowers and Parthenocissus

You have seen ivy, ivy is a very common plant, it has other names, such as stone dragon, maple vine, Cordyceps sinensis, red silk grass, ivy and medicinal value, you want to know how to cultivate ivy? This is an editor who introduces ivy cultivation techniques and disease prevention.

Cultivation techniques of Ivy

Ivy can be propagated by sowing, cutting and layering.

Sowing and reproduction

After harvest, peel the seeds from the pericarp. After washing and drying, they can be stored in wet sand for a winter. Heat preservation and moisturizing are beneficial to germination. Next spring, early spring can be planted in mid-March, film cover, May. It can appear in the first ten days and can be produced after 1 to 2 years of culture.

Cutting propagation

In early spring, cut the stem into 20 to 30 centimeters, insert it into an open seedbed, fill it with water, keep it moist, and quickly let the grapevines survive. You can also use twigs with leaves, shade and watering in summer and autumn, and you can pump water quickly. New buds have a high survival rate and are widely used. Insert a hard branch from March to April, cut the branch into 10-15 cm parts and insert it into the soil. The feet are permeable and keep moist. Twigs are inserted into the new year and carried out in the summer.

Stratified propagation

The wave bead method can be used in wet and cloudless weather in rainy season with high survival rate. Transplanting can be separated in autumn and planted next year.

Matters needing attention

Seed sand and germination

When the berries are purple in September, they are immediately removed, washed and dried, and surface sterilized with 0.05% carbendazim solution. After drainage, store the wet sand layer. In early March, a good year, soak the seeds in warm water at 45 °C for two days, change the water twice a day, then mix them with 2:1 wet sand seeds and place them in a shelter from the wind. The sun, cover the straw bag and spray water to keep it moist. . After about 20 days, 20% of the seeds will be sown in white.

Sowing seeds

First of all, the seed bed will be leveled, watered, the seeds and sand will be sown on the bed, the sowing amount is 100 grams per square meter. The forest is covered with 1 centimeter of loose humus soil, covered with a small arch shed and covered with polyethylene plastic film.

Seedling management

After unearthed cotyledons, the film was exposed to sunny and rainy days to increase soil temperature, promote the emergence of neat seedlings, and prevent damage from beetles. In addition, always sprinkle water to keep the soil moist.

Migration and post-management

After three real leaves are unfolded, they are transplanted at a density of 1 × 1 foot on a cloudy day or 3 p.m. Pour feces (1:8) immediately after planting. You shouldn't keep water for too long in the rainy season. After two months, the length of the grapevine is usually more than 60 centimeters.

This is a good time to use topping to prevent the grapevines from twisting each other and to make the vines thicker and stronger. Pick up the heart once a month, plus auxiliary support. With the above measures, in the defoliation stage, the average thickness of seedlings can reach 0.5 cm or more, and can be planted.

Liquid fertilizer can be applied 2 to 3 times during the growing season.

And often remove loose soil to make fences so as not to be submerged by grass to promote its strong growth. Ivy is afraid of waterlogging, so we should pay attention to prevent the soil from accumulating water. Ivy is resistant to pruning. In the process of growth, the branches and doors of doors and windows can be repaired to keep them clean, beautiful and convenient.

It turns out that seed breeding is also a good method, with a seedling emergence rate of 80%, and seedling management is more convenient. Beads can be made in the spring, and old plant branches are bent and buried in the soil to produce roots. In the spring of a good year, my mother was cut off and planted separately. The survival of ivy is very strong, so reproduction is easy to survive. After growing for a year, seedlings can be transplanted and planted. When planting, turn over the soil and apply enough base fertilizer. When the seedlings grow to 1 meter, apply leads and ropes to the climbing object.

Administration and Management

Ivy can be planted in shade and sunlight, while cold areas can be planted in sunny areas. Ivy has strong resistance to chloride and is suitable for industrial and mining areas with serious air pollution. Seedlings can be widely managed after one year of growth and can withstand a low temperature of-20 °C in winter without cold protection.

Transplanting or planting is carried out in the deciduous stage. Before planting, use organic fertilizer as base fertilizer, cut off long stem, pour water, and it is easy to survive.

The height of one-year-old seedlings can reach one meter. The walls of a house, building or courtyard should be planted in the same place. The pit should be 50 cm away from the wall. The distance between plants should be 1.5 mm. The balcony of the building can be potted, the seedling pot is close to the wall, and the branches can quickly absorb the wall.

Disease and insect pest control of ivy disease

Disease prevention

The diseases of ivy are powdery mildew, leaf spot and anthracnose. Common aphid harm.

Because of its strong resistance, ivy has fewer diseases and insect pests, but it also occurs from time to time. Especially in the rainy season, powdery mildew, leaf spot and anthracnose are easy to occur due to high temperature and high humidity. 50% of the bacteria can be used when a disease occurs. Ling, toluene sulfonic acid or chlorothalonil 500 times 800 times liquid control, sprayed every 7 days or so, 2 times 3 times continuously.

Pest control

Insect pests are mainly aphids, which can be controlled by 500-1000 times with indomethacin, chlorpyrifos or cypermethrin.
