Amaranth is one of the favorite vegetables of Xiaobian. The first time people who come into contact with leeks will be scared by the red soup they cook. In fact, leeks are the most common wild vegetables in the countryside. People often cook them long ago. . The nutritional value of leek is also very rich. Now many people in the restaurant will order the delicious taste of amaranth. Today, I will follow a small series of Huinong.com to learn about the cultivation time and cultivation method of amaranth.
First, planting time
Amaranth can be grown in the spring to autumn frost-free period. Open field cultivation is generally available from late March to early August. Covering cultivation in greenhouses or small arch sheds can be planted early for about twenty days, and in late February. Under normal circumstances, it is generally available for about thirty-five days after sowing.
Second, high-yield planting methods
Variety selection
The selection of varieties should be determined according to seasonality and local consumption habits. Generally, in the early spring or winter, the varieties with strong cold resistance and red leeks should be used. In other seasons, all green leeks or red leeks with strong resistance to pests and diseases are generally used. Generally, from late February to late March, it is advisable to use early-maturing and cold-tolerant varieties of sharp-leaved red rice bran and sharp-leaved red glutinous rice. From early April to late May, red sorghum, Dahongpao, white rice bran, willow stalk, etc. should be selected. Varieties, from early June to early August, summer and autumn cultivation should use more heat-resistant white rice bran, willow carp, red glutinous rice and other varieties.
2. Seeding technology
(1) soaking seeds and germination
This method firstly needs to immerse the leek seeds in cold water for about a day. During the soaking process, remember to wash them several times in order to increase the water absorption. Then wrap it in a breathable gauze, cover it with a wet towel, and put it in a fifteen to twenty degrees Celsius environment for germination. When most of the seeds are white, they can be sown. This method is usually early spring or winter, and other seasons can be directly sown.
(2) Soil preparation and fertilization
Amaranth planting should choose loose and fertile soil and better fertilizer and water retention. Amaranth prefers alkaline soil. When fertilizing the site, 5,000 kg of decomposed organic fertilizer and 50 kg of compound fertilizer can be applied per mu, and the width of the crucible is 1 to 1.2 m, the width of the ditch is 0.3 m, and the ditch is 0.15 to 0.2 m.
(3) Seeding method
The seeds of amaranth are small, and sowing with some fine sand or fine soil can make the seeding uniform, and the amount of seed per acre is 0.25-0.5 kg. It can be spread or broadcasted in a flat manner. The four-toothed scorpion can be lightly smashed or not smashed. The stalker can be slightly deeper in spring, shallower in summer, shallowly covered with soil, and then repressed, watering, waiting for emergence. In the winter and early spring, add a thin layer of straw to moisturize, and then cover with a layer of film insulation. Cover the sunscreen in summer.
3. Daejeon management
(1) Temperature management
After the winter and early spring, the leek uncovers the mulch and covering. After watering, a small arch shed is built in the shed to facilitate heat preservation. In the evening, a small layer of straw curtain is placed on the shed in the evening when the outside temperature is low. After the emergence of the summer, cover the sunscreen in time, take the early cover and expose it.
(2) Water management
In the winter and early spring, the leek should always keep the soil moist, and the small water should be poured. Try to choose watering in the sunny morning, and apply a 0.2% urea aqueous solution after the seedlings, and then apply it once every 7 to 10 days to promote growth. Appropriately increase the amount of water in the summer, usually watering in the morning and evening.
(3) Reasonable topdressing
Amaranth should be used for multiple topdressing. Generally, when the seedlings have 2 true leaves, the first fat is chased. After 10 to 12 days, the second fat is chased. After each harvest, the topdressing is performed once. The type of fertilizer is mainly nitrogen fertilizer, and each time per mu, there can be 1500-2000 kg of thin human excrement urine and 5-10 kg of urea.
The above is the technical point of amaranth planting, I hope to help the friends who want to learn, you also want to learn what kind of planting technology, you can leave a message.
