How to harvest torch seeds? What are the methods of raising seedlings?

Torch, also known as antler lacquer, originating from Europe and the United States, is a small deciduous tree of the genus Salina of the family Lacqueraceae. The torch is mainly planted in the south, north and northwest of Northeast China, with beautiful trees, green leaves in spring and summer, red leaves after autumn, large forests such as a sea of fire, with high spectacular landscape value. So how to harvest torch seeds? What are the methods of raising seedlings? Next, let's have a look with the editor.

First, how to harvest torch seeds?

The fruit period of torch tree is usually in early September in autumn. After the fruit is ripe, pick the mother tree that is growing well. The seeds are taken out from the fruit, collected and then air-dried, carefully selected and other operations. Finally, put the dried seeds in a dry and cool place, ventilated and stored to avoid dampness and mildew. Before sowing, it is necessary to avoid diseases and insect pests caused by insects and mice, so as to ensure the quality of the seeds.

The seeds before sowing need a series of fine treatments, because the torch tree seeds are small, there are red needle-like hairs outside the seed coat, and they are hard and waxy, so it is difficult to sprout, which will reduce the germination rate.

Second, what are the methods of raising seedlings with torches?

1. Land preparation

For the nursery suitable for the survival of torch seedlings, soil preparation in the first and middle of March is the most suitable, it is necessary to dig deep and fine rake, hoe weeds and avoid nutrient loss. In order to ensure the fertility of the soil, it is necessary to apply sufficient base fertilizer, about 3t mature organic fertilizer and 30~50kg compound fertilizer during soil preparation.

2. Sowing and raising seedlings

The general torch nursery beds are mainly low beds, under the trail 10~15cm, the north and south dynasties are conducive to daylighting, width 1.2m, length does not make specific provisions, determined by the terrain. From late March to early April, the temperature and humidity are suitable for sowing. Before sowing, the seedbed should be filled with enough bottom water to ensure humidity. When the water seeps into the deep part of the nursery bed, the row spacing of 30cm shall prevail, and the cable shall be trenched. Prepare the seed sand of 6~7kg per mu, stir evenly and spread sparsely, so as to prevent the emergence rate from being reduced due to too high or too small seed density. After sowing, it is necessary to gently fill and press a layer of flat and thin soil of 1.5~2cm and cover it with thin film to keep the seeds warm and humid. In order to prevent the seedling from being waterlogged to death, a drainage ditch must be opened around the seedling bed. In particular, it should be noted that the seed needs enough water before germination, and if it is irrigated again, it will cause the seeds to be waterlogged and moldy. Usually after 2-3 weeks, the seedlings basically come out.

3. Interseedling and fixed seedling

The planting density of torch seedlings should be moderately dense, because the main stem is often tilted to one side, and if there is no corresponding support, it will lead to the death of the seedlings. When the seedlings grow out of 2-3 true leaves, the first seedling is carried out, and when the leaves overlap each other, the seedlings are carried out for the second time, in accordance with the principle of keeping the best and removing the weak, and remove the seedlings that are underdeveloped, suffer from diseases and insect pests, suffer from mechanical damage, and have too high density. Keep good seedlings. According to the 7~8cm distance between seedlings, if the spacing is too large or too small, it is necessary to replant. In order to avoid drought and death of seedlings due to lack of water, it is appropriate to choose cloudy day or evening.

The above is the introduction of the torch. Torch trees are easy to reproduce, and the types of propagation are usually divided into three types: sowing propagation, root tillering propagation and root-burying propagation, in which sowing reproduction is widely used in production because of the low probability of diseases and insect pests. In addition to the ornamental value, torch tree has a wide range of uses in leaves, fruits, bark, seeds and wood.
