Licorice has strong adaptability. What kind of environmental conditions are needed for planting?

Licorice, alias sweet grass root, scent grass, grass. Perennial herb with rhizome and root, diameter 1-3 cm, brown skin and light yellow skin. Delicious. Stems, much branched, 30- 120 cm tall, with defective scales, spiny glands and white or brown villi. Bean plants. Tel into the rhizome and rhizome. It has medicinal value. Licorice grows in the north temperate zone, in the plains, mountains or river valleys with an altitude of 0 to 200 meters. The soil is more sandy. The soil is preferably neutral or microbial. Happy photos, ecological environment with temperature difference between day and night. China is suitable for planting licorice in North China and Northwest China.

To cultivate Glycyrrhiza uralensis Fisch, the groundwater level should be 1.50 m, the drainage condition is good, the soil layer thickness is more than 2 m, there is no flat plate inside, the pH is about 8, and the sandy soil is convenient for irrigation. It's best to turn into autumn blush. If you can't catch up with autumn, spring is fine, but you must make sure that the soil is love and break the land, otherwise it will affect the whole seedling.

Glycyrrhiza uralensis Fisch has strong adaptability and strong resistance, and has certain economic value. Cultivation techniques and excellent varieties of medicinal plant Glycyrrhiza uralensis Fisch are the internal factors for high yield of Glycyrrhiza uralensis Fisch. Using seeds as sowing materials, grind the seeds with an electric mill, or lift the seeds into a ceramic pot and add 30ml concentrated sulfuric acid 1kg seeds. Repeatedly stirring, washing with water at 20℃ for 7 hours in the morning, and the germination rate is over 90%. The sowing distance of the seedlings is 30 cm, and the seedlings are kept at 18.5 cm to 20 cm.

Irrigation of Glycyrrhiza uralensis Fisch usually needs to keep the soil moist before and after seedling, so as to benefit seedlings and seedlings. The specific irrigation should depend on the soil type and salt content: for sandy soil or slightly salty soil, irrigation can be carried out after sowing; Soil adhesion or high salinity is the key to watering. Licorice is planted before sowing. It's a lotus. Generally, plants grow very long.

Licorice can be sown in spring, summer and autumn. Among them, the summer in May is the best, when the temperature is high, the seedlings emerge quickly and the growth time before winter is longer. Before applying 4000 kg of high-quality farm children's fertilizer per mu, the phosphorus consumption per mu was 35 kg. If the spacing between plants planted with seeds is 15 cm, the depth is 2.50-3 cm, and each hole has 3-5 seeds, soil should be paved.

Weeds in China are usually carried out in seedling years, especially at seedling stage. In terms of time, seedlings are usually cultured for 3-4 times, and the amount of medium can be reduced appropriately in the future. From the second year, the roots of Ganer began to grow, and weeds were difficult to compete with them, so it was no longer necessary to reclaim grassland. Fertilization is necessary before sowing. Sowing can be treated with early spring fertilizer, and each mu of organic fertilizer is sealed before winter. The root of Glycyrrhiza uralensis Fisch has nodules, which have the function of nitrogen, usually not nitrogen fertilizer.

Pests and diseases and their prevention and control of powdery mildew and rust in rainy season, red spiders are prone to occur in dry season, and 40% of le cauliflower can be used 1000 times to 1500 times. After being invaded by fungi, yellow-brown blister Petri dishes appeared on the back of leaves, and the strains were concentrated. In the initial spray of 0.3-0.4, is it ruddy or 400 times liquid of 97% enemy steel? After being infected by fungi, the leaves are round and irregular, the center is grayish brown, and the edges are brown. There are grayish-black molds on both sides of the lesion, and the concentration is concentrated. The initial spray is 1: 1: 1? Wear powder 16 o bode solution or 70% methyl oak 1500? Two thousand times

The roots of licorice must be dug deep, not shaken or hurt. After digging, remove the residual stems and soil to avoid water accumulation, take the main roots and lateral roots, take out the dry heads, blow dry the hair until it is tied into small hands, and then blow dry; It can also be excavated in front of licorice stems, but the quality of heat preservation in autumn is better.

If it is cultivated artificially, it should be planted every year, and a big and complete seed can be obtained in the flowering pod. Seeds should be planted in pods, which is the best medium. The seeds are low and simple, and the seeds should not be premature, otherwise it will affect the germination rate of the seeds after sowing and cause the lack of seedlings.
