How to plant red maple seeds?

Red maple branches and leaves are purplish red, gorgeous, high ornamental value, widely used in garden green space and courtyard to do ornamental trees, mainly solitary planting, scattered planting, should be arranged in the center of the lawn, before and after tall buildings, corners and other places, red leaves and green trees complement each other, can also be potted into root, stone, cliff, withered and other shapes, let's take a look at how red maple seeds are planted!

Seed selection method of Acer truncatum

Red maple seeds should first be selected before sowing. Whether the seeds are good or not is directly related to the success of sowing. It is best to choose the seeds harvested in the same year, because the longer the seeds are preserved, the lower the germination rate. At the same time, we should choose full seeds, no incomplete or abnormal seeds, no diseases and insect pests.

Disinfection and germination of red maple seeds

1. Disinfection: disinfection includes two concepts: one refers to the disinfection of seeds, and the other refers to the disinfection of sowing substrates. Families usually soak seeds in hot water for about 60 ℃ for a quarter of an hour, and then use warm hot water to accelerate germination for 12 hours. The best way to disinfect the substrate used for sowing is to stir-fry it in a pan so that any diseases and insects can be scalded to death.

2. Sprouting: usually knead off the wings of the seed half a month before planting, soak the seed in warm hot water (the temperature is about the same as facial water) for 12 to 24 hours, until the seed absorbs water and expands.

Seed sowing method of Acer truncatum

1. Trench sowing: generally speaking, red maple seeds begin to germinate in 15-20 days, and all seeds can be sown when the germination reaches 20% (or you can pick out germinated seeds first). Sow 3 kg red maple seeds per mu, open a ditch 10 cm deep and 20 cm wide on the ridges that have been made, sow the seeds together with sand into the open ditches, and sow them evenly.

2. Cover soil support shed: cover the seeds with a layer of moist fine soil after sowing. The cover soil should not be too thick, which can affect sprouting. At the same time, support the small plastic shed, then support the sunscreen arch shed on the plastic shed, pay attention to the plastic arch shed at the bottom, the sunscreen arch shed at the top, the distance between the two arch sheds should be greater than 20 cm, in order to maintain the effect of ventilation and cooling.

3. Daily management: one month after sowing is the critical period for red maple sprouting. It is often observed to maintain the temperature and humidity in the arch shed, and the hand is not hot to indicate the temperature. It is found that the temperature is too high and should be ventilated immediately. Spray at both ends of the film arch shed is used to reduce the temperature. When the seedling grows to 5 cm to 10 cm, the film arch shed is removed, and the sunscreen arch shed continues to be retained. After the seedlings grow to 20 to 30 centimeters, the sunscreen will be opened sooner or later, and the sunscreen will be covered at noon. After 2 weeks, all the sunscreen will be removed.

4. Weeding with water and fertilizer: foliar fertilizer or a small amount of urea can be used after the seedlings grow to 10 centimeters. Remember that fertilization should follow the method of a small number of times and should not be excessive at one time to prevent seedling burning. At present, there is no effective herbicide that does not harm red maple seedlings, so the method of manual weeding is generally used.
