High quality and high yield cultivation techniques of amaranth
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 is 10-12 kilograms per 667 square meters, and the seeding rate per 667 square meters 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 manure and urine, or covered with 1 cm of dried fine soil. Then cover the mulch film and set up a small arch shed. The membrane 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 solution, 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 covered with a 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 entrance of the shed door when there is a north wind. (5) Early harvesting 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. After the leeks are released from the leeks, 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.
