1. Selection of varieties (1) Jiangxi Reed (2) Thai chives (3) Guangxi white seed 2. Fertilizing the soil The early spring leeks are cultivated in the greenhouse, and they are usually intercropped or intercropped with vegetables such as solanaceous fruits and melons. Apply 5 tons of organic fertilizer per 667 square meters, 20 kilograms of urea, spread it on the soil surface, and turn it over to the ground. It is generally 1.2 meters wide and sorghum, which is easy to cover small arch sheds and other vegetables. 3. Sowing season Early spring sowing can be carried out in the greenhouse after the horror, and late autumn planting will end in mid-October even if it is covered under the greenhouse. 4. Seeding amount The live broadcast amount is 10-12 kilograms per 667 square meters, and the seeding rate per 667 square meters of seedlings is more than 20 kilograms. 5. Seeding method In the early spring, the seeding method is used. Because the seeds are large, they are covered with nails and loose soil after sowing, or covered with thick human and animal excrement, or covered with 1 cm of dried fine soil that has been screened to facilitate emergence. Then cover the mulch film and set up a small arch shed. The mulch film can be removed by sealing until 80% of the seeds are emerged. 6. Field management (1) Disease prevention After uncovering the film, spray with 75% chlorothalonil 500 times, once every 7-10 days, to prevent rickets. (2) Weeding In early spring, because weeds grow faster than leeks, we must weed them in time. (3) Topdressing When 2 leaves are one heart, 10 kg of urea can be applied once per 667 square meters. It can also be used to increase yield and plant power 2003 for leaf surface topdressing to promote its rapid growth. (4) Insulation Low temperature in early spring is the enemy of amaranth production. After the seedlings were uncovered, the first batch of amaranth was harvested. This period was mainly heat preservation. Because the suitable temperature for growth is about 25 °C, the management principle is: when the temperature in the shed is lower than 25 °C, the closed shed is small arch shed; when the temperature is higher than 25 °C, the shed door is opened and the small arch shed is covered; when it exceeds 35 °C, Uncover the film and ventilate, reduce temperature and reduce humidity. It is strictly forbidden to open the north exit of the shed door when there is a north wind. (5) Early harvest According to the market conditions, when the seedlings can basically be listed, they will be in the morning market. 7. Interplanting other vegetable crops at the right time In the greenhouse, the leeks are cultivated in the early spring, and after the leeks are released, the vegetables in the preparation and intercropping can be planted to improve the utilization and efficiency of the greenhouse. 8. Cultivation of chives in late autumn The shed should be buckled in early October to prevent frost. The latest planting period should end in mid-October. Its cultivation techniques are the same as those in early spring. Disclaimer: Some articles on this website are transferred from the Internet.

They are the effective ingredients in the preparations. They are various powders, crystals, extracts, etc., prepared by chemical synthesis, plant extraction or biotechnology, but Substances that the patient cannot take directly. API is intended to be used in any substance or mixture of substances in the manufacture of pharmaceuticals, and when used in pharmaceuticals, it becomes an active ingredient of the pharmaceuticals. Such substances have pharmacological activity or other direct effects in the diagnosis, treatment, symptom relief, treatment or prevention of diseases, or can affect the function or structure of the body. According to its source, active pharmaceutical ingredients are divided into two categories: synthetic chemical active Pharmaceutical ingredients and natural chemical active Pharmaceutical ingredients.
