The planting method of the latest Tianqi
Tianqi is a kind of traditional Chinese medicine used to stop bleeding and tonify blood and enhance immunity. It can be used to make tea or boil soup to make medicinal meals. At the same time, it can also be used as medicine with high use value. Tianqi is planted in many places in our country. Today, we are mainly going to learn how to plant Tianqi well.
1. Soil preparation and fertilization
The planting land of Tianqi is generally selected in a place with a slight slope, which is convenient for drainage and watering, and the water source near the planting site should be more abundant, and the soil had better contain organic humus soil or sand or loam. It is not suitable to grow in heavy clay, so the land is very easy to consolidate and is not suitable for the tuber growth of Tianqi. At the same time, the planting land cannot choose the land where the previous crop is eggplant crops. The planting land should be left vacant for at least a year before planting, and the soil should be deeply ploughed during soil preparation, and the soil needs to be disinfected and sterilized before planting. About 5,000 jin of farm rotten fertilizer per mu should be used as base fertilizer, and the border land should be well ditched.
2. Sowing and raising seedlings
When sowing is carried out in October or November every year, before sowing, the seeds of Tianqi need to be screened and sterilized with a new high-fat membrane, which can improve the germination rate of seeds and isolate the virus. does not affect the germination of seeds, sowing generally according to row spacing of 6 cm, plant spacing of 5 cm or so, and finally need to cover a layer of straw This can maintain the moisture of the soil, but also play a thermal insulation effect.
3. Seedling stage management
The main attention of seedling management is the management of field moisture and weeding. When the weather is relatively dry, watering should be carried out frequently, usually every three to five days or so. Secondly, when there are more Rain Water, the drainage system in the field should be dredged in time for drainage, and then weeding should be carried out regularly, usually by pulling weeds manually. Finally, fertilizer is applied when necessary to maintain the normal growth of Tianqi.
4. Field management
First of all, we need to transplant the seedlings in the field. Generally, we have to go through an one-year seedling raising stage before transplanting. We should be careful when pulling out the seedlings, do not hurt its roots, and pull out the weak and diseased seedlings when selecting the seedlings. Then plant according to the row spacing of 20 cm and the plant spacing of 15 cm. Watering should be carried out in time after planting, which can improve the survival rate of Tianqi, and then build a shade when the sun is strong in summer, so as not to affect the growth of Tianqi. In the growth process of the weather, we need to apply fertilizer according to the principle of a small amount of fertilizer for many times, so that the fruit of Tianqi is full, and in order to prevent unnecessary nutrient consumption, all the flowers can be removed. It is that several kinds of nutrients can be supplied to the underground roots to promote the rapid growth of rhizomes.
5. Pest control
The most common diseases and insect pests of Tianqi are blight, anthrax, root rot, aphids and scale insects. For a series of fungal diseases caused by too much water in the field, coupled with high temperature, we can usually use Bordeaux solution or chlorothalonil or carbendazim for control, while aphids and scale insects can be controlled with dimethoate milk.
