The latest culture method of Hongqiancao

Red thousand layers, also known as bottle brush wood, Jinbao tree, etc., are evergreen shrubs or small trees of the myrtle family, with extremely peculiar spikes in shape and bright colors, which can be used as flower arrangements. at the same time, they are also the preferred tree species for courtyard viewing, street landscape and community greening, and can also be used as windbreaks, green forests or potted plants to make high-grade bonsai after pruning and shaping. Let's take a look at the breeding methods of red thousands of layers.

The growth habit of Radix Scutellariae

Red thousand layers like warm and hot climate, can withstand the scorching sun and heat, not very cold-resistant, shade-intolerant, like fertile and moist acid soil, but also can withstand thin and dry soil. Slow growth, strong sprouting, resistance to pruning and wind resistance. In the north, it can only be potted in a high temperature greenhouse. The seedlings can survive the winter in the open field, and can withstand the low temperature of-10 ℃ and the high temperature of 45 ℃. The suitable temperature for growth is about 25 ℃, and the moisture content is not strict, but it grows faster under humid conditions. Because it is extremely resistant to drought and barren, it can also be cultivated in barren hills or forest parks in the suburbs of cities and towns.

The breeding method of Radix Scutellariae

1. Cutting method: cut semi-mature non-flowering lateral branches in March, 10-12 cm long, with 1-year mature branches at the base, cut them in semi-sand and mud, keep the shade in a shed to maintain humidity, root in about 40 days, and put on the basin after the root group grows vigorously.

2. Sowing method: in April, the mature fruit was collected, the seeds were evenly mixed with fine sand, and then sown, slightly covered with fine soil to maintain humidity, and germinated in about 35 days. The seedling height was about 15 cm, that is, the seedling was put on the pot with soil, and a large basin was selected for growth.

The culture method of red thousand layer

1, seedling: red thousand layer culture soil can not be too wet, nor too dry, the size of the soil ball to a diameter of 40cm 50cm, column height of 30cm 40cm, into a cylindrical shape, do not pot bottom shape. Immediately after the seedling is raised, it is wrapped with straw or other materials, loaded and unloaded light to prevent the soil balls from falling and the roots exposed. This is an important part of survival.

2, planting: red thousand layer tree hole with 80x80 cm is appropriate, to apply good base fertilizer, according to soil and miscellaneous fertilizer at 1:1, add pure soil 5 cm thick compaction, to avoid root contact with fertilizer and burn, remove soil ball packaging, put the plant in the hole, the soil sphere and the ground, and then layered fill tamping, so that there is no gap in the bottom, immediately after planting.

3. Pruning: the water balance will not return to normal soon after transplanting, and pruning before seedling is an effective measure to reduce water transpiration. It is helpful to maintain the water balance in the plant, especially in the hot summer, the evaporation is large, and pruning is more important. The branches and leaves cut off account for about 1/3 of the whole plant, mainly the inner chamber branch (shade branch) and the newly extracted twig, which should be transplanted in winter and spring, and the top branch with flower bud should be preserved so that it can blossom in summer after transplantation, and get the greening effect.

4. Watering: once or twice a day after planting, the red layer should be watered through the soil layer, and the branches and leaves should be sprayed at the same time to keep the branches and leaves moist, reduce water transpiration and maintain water balance in the plant. Spraying water on branches and leaves is another important link to survive after planting. Some plants with scattered soil, such as strengthening the spraying of water on branches and leaves, can also survive and be transplanted between June and September, when the weather is hot and the amount of water evaporation is large, so the times of spraying water on branches and leaves should be increased appropriately.

5. Fertilization: fertilization in red layer is very important for the rapid recovery of plant growth. Nitrogen fertilizer can be applied thinly once 15 days after planting and high-quality organic fertilizer once a month later. In the future, high-quality organic fertilizer can be applied twice a year. Pruning and pruning once a year after flowering can control the growth height and maintain the beautiful shape of the tree, which can promote the germination and flowering of more new branches.

6. Diseases and insect pests: stem rot is the main disease of red thousand layer, so it is appropriate to pull out diseased seedlings and spray Bordeaux solution to control. The pests include ground tiger, mole cricket, green weevil and so on, which can be controlled by 1000 times of trichlorfon or 1000 times of dichlorvos.
