The cultivation technology of amaranth

1 Variety selection

Early-maturing cultivation is mainly based on dry planting, and it is better to use high-quality, high-yield, disease-resistant and disease-resistant leeks, which have strong resistance to stress, broad adaptability, and good commercial quality. For example, E. sinensis No. 1, Guangdong Daguqing and Hunan white flowers. Wait.

2 Seeding and nursery

Dry-seedlings are mostly seeded or seeded and transplanted, and live broadcasts in Shandong, Henan, and other places are generally conducted around mid-April and can continue until August. If conservation facilities are used, the sowing date can be advanced. Live direct seeding can be drilled or on-demand, spacing 30~35cm, on-demand hole distance 15~20cm, seed 23 seeds per hole, live seed 667m2 about 10kg, when the seedling height 3cm or so will be in batches, finally by 15 ~ 20cm Distance colonization. In early spring, the seedling temperature is low, seedlings are too late, and sowing is required. Seeds are soaked for 12 to 24 hours before sowing, and then germinated at a temperature of 25 to 30°C. Most of the seeds are sown after sowing. After sowing, fine soil 1cm is covered, and the plastic film is covered. Warming and moisturizing, after the emergence of the film withdrawal, seedling height 15 ~ 18cm when planting, set the plant spacing of 15 ~ 20cm, 1 to 2 per hole. Transplanting of nursery seedlings is usually carried out by seedling raising and seeding, and the seedling quantity per 667m2 seedling is about 18kg.

3 Planting and Management

For dry planting, we should choose land plots with high topography and moist and fertile soil. After planting live trees, we should diligently cultivate loose soil and raise the ground temperature. In summer, the temperature rises, the plants grow fast, and the amount of water required for fertilizers is large. It is necessary to diligently water and pour water, and combine topdressing with quick-acting nitrogen fertilizers. The topdressing concentration should not be too high to avoid burning seedlings. Should grasp the principle of first light and heavy. In order to promote the rapid growth of stems and leaves, early picking on the market, 2010-6 gibberellin can be sprayed on the seedlings, spraying 1 water every 7 to 10 days, a total of 2 ~ times. Into the autumn, the weather turns cold and we should timely cultivating weeds and topdressing, and pay attention to the control of red spiders and other pests.

4 Harvesting

Leek harvested many times in his life, timely harvest is an important part of winning high yield, when the seedlings up to about 30cm can be picking up the market. The first pick left 2 knots at the base to promote germination, and the subsequent harvest criteria and stay for the first time. Do not leave too many knots, so as to avoid excessive side branches, nutritional dispersion, affect the quality and yield.

After each harvest, it is also timely to apply topdressing nitrogen fertilizer, with a certain amount of phosphorus and potassium fertilizer, and watering or flushing with water, the harvest period is generally up to 4 to 6 months, and the output is 5000 to 7000kg/667m2.
