Introduction to Boston Ivy Cultivation Techniques and Disease Prevention and Control Methods
You have seen ivy. Ivy is a very common plant. It has other names, such as Shilong, maple vine, small insect grass, red silk grass, etc. Ivy also has medicinal value. Do you want to know how to cultivate ivy? This is a small introduction to ivy cultivation techniques and disease prevention.
Ivy Cultivation Techniques
Ivy can be propagated by sowing, cutting, and layering methods.
Sowing and Propagation
After harvest, peel the seeds from the fruit skin. After washing and drying, they can be stored in moist sand for one winter. Heat preservation and moisture retention are beneficial for germination. Next spring, early spring can be planted in mid-March, with film covering, in May. They can emerge in the first ten days, and can be produced after 1 to 2 years of cultivation.
Cutting Propagation
In early spring, cut the stems into 20 to 30 cm sections, insert them into an open seedbed, fill with water, keep moist, and the vines will quickly survive. You can also use tender branches with leaves in summer and autumn, with shading and watering, and they can quickly take root. New shoots have a high survival rate and are widely used. Insert hard branches from March to April, cut the hard branches into 10-15 cm sections and insert them into the soil, keep the foot permeable and maintain moisture. Softwood cuttings are inserted in the new year and carried out in summer.
Layering Propagation
The wave bead method can be used in the rainy season during humid and cloudless weather, with a high survival rate. Transplanting can be separated in autumn and planted the next year.
Precautions
Seed Sand Storage and Germination
When the berries mature to purple in September, take them out immediately, wash and dry them, and sterilize the surface with a 0.05% carbendazim solution. After draining, store in a wet sand layer. In early March of the following year, soak the seeds in 45°C warm water for two days, changing the water twice a day, then mix the seeds with wet sand at a 2:1 ratio, place them in a windproof place away from the sun, cover with a grass bag, and spray water to keep them moist. After about 20 days, 20% of the seeds will be white and can be sown.
Sowing
First, level the seedbed, water it, and sow the seeds and sand on the bed, with a sowing rate of 100 grams per square meter. Cover with 1 cm thick loose humus soil under the forest, cover with a small arched shed, and cover with polyethylene plastic film.
Seedling Management
After the cotyledons emerge, expose the film on sunny days and cover it on rainy days to increase soil temperature, promote uniform seedling emergence, and prevent damage by scarab beetles. In addition, always sprinkle water to keep the soil moist.
Transplanting and Later Management
After three true leaves have unfolded, choose a cloudy day or after 3 p.m. and transplant them at a density of 1 x 1 foot. Immediately after planting, pour manure (1:8) once. In the rainy season, you should not let water stand for too long. After two months, the vine length usually exceeds 60 cm, and at this point they can enter
This is the first time topping is used to prevent the vines from twisting around each other and to make the vines thicker and stronger. Pinch the growing tips once a month, and add auxiliary support. With the above measures, during the leaf-fall period, the average thickness of the seedlings can reach 0.5 cm or more, and they can be planted.
During the growing season, liquid fertilizer can be applied 2 to 3 times.
And frequently remove loose soil to make a fence, so as not to be overwhelmed by grass, to promote strong growth. Ivy is afraid of waterlogging, so attention should be paid to preventing soil water accumulation. Ivy is resistant to pruning. During growth, branches at doors and windows and gates can be trimmed to keep it clean, beautiful, and convenient.
It turns out that seed breeding is also a good method, with an emergence rate of up to 80%, and seedling management is also more convenient. Beading can be carried out in spring, bending old plant branches and burying them in soil to produce roots. In the following spring, cut off the mother plant and plant them separately. Ivy's survival is very strong, so propagation easily survives. After one year of growth, seedlings can be transplanted and planted. When planting, turn over the soil and apply sufficient base fertilizer. When the seedlings grow to 1 m, apply wires and ropes to the climbing object.
Management
Ivy can be planted in shade and in sunlight; in cold areas, plant it 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 low temperatures of -20°C in winter without cold protection.
Transplanting or planting is carried out during the leaf-fall period. Before planting, apply organic fertilizer as base fertilizer, cut off long stems, pour water, and it is easy to survive.
Annual seedlings can reach a height of one meter. Walls of houses, buildings, or courtyard walls should be planted in the same place. The pit should be 50 cm away from the wall. The spacing between plants should be 1.5 mm. Balconies of buildings can be potted; place the seedling pot close to the wall, and the branches will quickly attach to the wall.
Pest and Disease Prevention and Control of Ivy
Disease Prevention
Ivy diseases are powdery mildew, leaf spot, and anthracnose. Common aphid damage.
Because of its strong resistance, ivy has fewer pests and diseases, but they also occur from time to time. Especially in the rainy season, due to high temperature and high humidity, powdery mildew, leaf spot, and anthracnose are prone to occur. When disease occurs, 50% Junling, thiophanate-methyl, or chlorothalonil 500-800 times liquid can be used for control, spraying once every 7 days or so, for 2-3 consecutive times.
Pest Control
Insect pests are mainly aphids, which can be controlled with indoxacarb, chlorpyrifos, or beta-cypermethrin at 500-1000 times.
