The latest seed price and planting method of oleander

Oleander, also known as winter, willow, peach, etc., is an evergreen erect shrub of the oleander family. It has large, gorgeous flowers and long flowering period, and is often used as an ornamental plant. It is widely cultivated in southern China, especially in southern China. Cultivation to the north of the Yangtze River requires overwintering in a greenhouse. Let's take a look at the seed price and planting methods of bamboo peach.

How much is the oleander seed per jin?

The price of oleander seeds is about 6070 yuan per jin, but it varies greatly due to the quality, variety and market of oleander seeds. Oleander propagation with cuttings and striping is easy to survive, but long-term cutting will also lead to variety degradation, so sowing is also a very important propagation method of oleander. Compared with cutting seedlings, bamboo peach seedlings are sturdy, tall and straight, large leaves, beautiful plant shape and long life, few diseases, and sowing is easy to produce variation, so it is an important method for breeding new varieties.

Sowing method of oleander

1. Seed collection: oleander is seldom pollinated naturally, and it is best to pollinate artificially (especially double petal varieties). The fruit is a purplish brown and oblong bony fruit, which ripens and cracks around December, and the seeds will fall automatically when they crack, so they should be collected in time and dried and stored.

2. Sowing method: oleander can be sowed in spring and summer, and the seeds are sown in plain sandy soil in a shallow basin. After a thin layer of soil is covered with a thin layer of soil, it is sprayed once with a fine hole spray pot to keep the soil moist. It germinates in 40 days at 10 ℃ at room temperature, and seedlings emerge in 20 days at 25 ℃.

3. Seedling management: oleander seedlings can be planted in pots when they grow to 3 to 4 true leaves with a height of 3 centimeters. Seeding seedlings grow slowly at seedling stage and then accelerate growth, usually blooming in 16 months. In order to make seedlings grow quickly, they can be moved to the open field for culture, and then put on the pot after cold weather.

Planting method of oleander

1. Watering: oleander likes water but is afraid of waterlogging. In case of continuous rainy days, stagnant water in the basin should be poured in time to prevent rotting roots. Watering should be dry and wet in spring and autumn to keep the basin soil moist. Watering should be done once a day in the morning and evening in summer, and watering should be controlled after entering the house in the middle of October.

2. Lighting: oleander likes sunshine and can adapt to shady environment, but there are few flowers planted in shade, so it should be preserved in a sunny place during the growth period, otherwise it will affect its ornamental value.

3. Temperature: oleander should be planted in leeward and sunny place. In winter, people can prevent freezing indoors, and the room temperature is not lower than O ℃. The temperature is too high and consumes nutrients, which is disadvantageous to the growth and flowering of the second year. In winter, those with high outdoor temperature can cultivate soil to keep out the cold.

4. Fertilization: oleander likes fertilizer. Thin liquid fertilizer can be applied every 20 days or so from outdoor to flower Xie (Frosts Descent). Oleander grows rapidly after autumn, and fertilizer and water can be applied every 15 days or so until entering the room.

5, pruning: oleander is generally trimmed four times, one is after Grain Rain, the second is in July and August, the third is in October, and the fourth is winter shearing. If you need to bloom indoors, you should move it to the indoor sunshine of about 15 ℃, and prune it immediately after flowering, otherwise there are few flowers and small flowers or even no flowering.

6. Diseases: oleander is often damaged by brown spot. At the initial stage of the disease, spraying 1000 times of 50% carbendazim wettable powder or 25% carbendazim wettable powder should strengthen management and increase tree power. 75% chlorothalonil can be sprayed.
