How to plant Wisteria sinensis
Today, the editor will explain how to plant Wisteria sinensis and share some experience in green plant maintenance regarding the cutting propagation techniques of Wisteria sinensis. Below, the editor will provide detailed answers for you.
1. Water and fertilizer management
Wisteria sinensis is relatively drought-tolerant, but during the nursery management period and the initial planting period in gardens, watering management should be strengthened. Sufficient water not only improves the survival rate of seedlings but also promotes vigorous growth. After sowing and before seedlings emerge, if the bed soil is dry, it is necessary to water appropriately. It is also important to water promptly after thinning to prevent the roots from becoming exposed to the wind. The bed soil should not be too wet to avoid excessive growth or disease occurrence. In the early growth stage of seedlings, the aboveground part and the root system begin to grow and form roots, but the distribution is relatively shallow. If the bed soil lacks moisture, it can easily cause seedling death. At this time, the surface bed soil should be kept moist, and the amount of watering can be increased appropriately while reducing the frequency of watering. From the rapid growth period to the late rapid growth period, the growth rate of seedlings is fast and the water demand is high. Watering can be less frequent but in larger amounts to fully meet the water needs of rapid seedling growth. In the later growth stage of seedlings, to prevent excessive growth and promote full lignification, watering should be controlled. During the abundant summer rainfall period, accumulated water should be drained promptly after heavy rain. Although Wisteria sinensis can tolerate moisture, it does not like waterlogging. Long-term waterlogging cannot cause its death but can still affect its growth, so it is beneficial to drain accumulated water promptly after heavy rain for seedling growth. For finished seedlings planted in gardens, water immediately after planting, then water again after 5 days, and again after another 10 days. After that, water once a month, and during summer rainy days, the amount of watering should be reduced. Both nursery seedlings and garden seedlings should be watered thoroughly and deeply before winter, and once in early spring to melt the frost.
Although Wisteria sinensis can tolerate poor soil, sufficient fertilizer can promote its vigorous growth. During the early stages of transplantation, decomposed and fermented manure should be used as a base fertilizer, with an application rate of 3000 kilograms per mu, mixed evenly with the planting soil. For seedlings planted in spring, a compound fertilizer with three main nutrients can be applied once in mid-July, and another application of farmyard manure can be made in late autumn combined with frost protection watering.
2. Propagation
Wisteria sinensis can be propagated by播种 (seeding), cutting, and division. Seeding is simple and can produce a large number of seedlings at once, so it is most commonly used.
In September to October, when the fruit is mature, collect the pods on a day with gentle wind and sunlight. After collection, place the pods in a well-lit area to dry, then winnow to remove impurities after a week, and store them in a clean cloth bag in a ventilated and cool place. Soaking the seeds before planting can help with germination.
The seedbed should be set up on flat ground with fertile soil, preferably neutral sandy loam. The seedbed should be fertilized with decomposed and fermented cattle and horse manure as a base fertilizer, at a rate of 2000 kilograms per mu, and the soil should be leveled and watered thoroughly before sowing. Sowing is best done from the end of March to the beginning of April, with a furrow depth of about 5 centimeters and a row spacing of 20 centimeters. After sowing, cover the soil with a thickness of 2 centimeters, with a seeding rate of 3 kilograms per mu. Seedlings can emerge in about a week. After the seedlings are all emerged, thinning can be done in half a month, keeping 5 to 6 seedlings per square meter. During the seedling stage, it is important to remove weeds, water appropriately, and prevent underground pests. Since Wisteria sinensis has a developed root system and grows fast, it can be sold in the nursery after one year, so there is no need for transplanting in nursery management. The survival rate of bare-root seedlings is very high when sold.
3. Pruning and shaping
Pruning and shaping Wisteria sinensis is relatively simple. Generally, it can be sold after one year of cultivation in the nursery, so there is not much pruning work. When used in landscaping, appropriate pruning should be done. If the seedlings are not uniform after planting, hedges can be pruned with a割灌机 (cutting machine) to make the hedge flat. If used for road slope planting, it is best to cut the plants flat after planting, as this improves survival rates and promotes branching, providing good slope protection and ornamental effects. In landscaping, pruning should be done according to its purpose. If used to decorate rockeries, do not let it grow too tall and prune frequently. For mass planting, attention should be paid to thinning to allow for ventilation and sunlight.
Disease and pest control
Pests that harm Wisteria sinensis include golden beetles, Elm long spotted aphids, Locust bean aphids, Chinese jujube autumn wax scale, Green grasshopper beetles, and Chinese bean weevil. If golden beetles occur, the adults can be killed with lights, and their larvae can be killed with a 40% methyl eugenol thiophosphate 200x solution. If Elm long spotted aphids or Locust bean aphids occur, a 3 to 5 degree Bordeaux mixture can be sprayed in winter to kill overwintering eggs. In the early stages of nymphs and adults, spray the back of the leaves with a 10% imidacloprid wettable powder 2000x solution or a 1.2% matrine nicotine oil 1000x solution. If affected by Chinese jujube autumn wax scale, spray with a 15% imidacloprid microcapsule dry suspension 2000x solution or a 95% acaricidal oil 400x solution. If affected by Green grasshopper beetles or Chinese bean weevil, manually catch the adults, and in severe cases, spray a 25% highly penetrable fenvalerate wettable powder 300x solution during the adult stage.
Wisteria sinensis has a strong resistance to diseases and no obvious diseases have been found during cultivation.
