New cultivation technology of amaranth in greenhouses
In winter greenhouse cultivation, you should choose color loquats with good palatability, high yield, strong stress resistance, and cold tolerance. Choose flat land with rich soil, convenient drainage and irrigation, and low weeds. Deep tillage of 15-20 cm in early November, combined with deep tillage After fertilization, the seeds can be sown in mid-to-late November. After dressing with a new high-fat film, mix the seed with an appropriate amount of fine sand and spread it evenly on the noodle surface. Press down with your feet or cover a layer of dung, and then cover the film. Then use a 2 meter long bamboo strip to support a small arch shed 70-80 cm high and cover it with a film. On the basis of watering the bottom of the water, no watering is required before emergence, and 5-7 days can emerge. After the cotyledons were unearthed, the mulching film was removed and the field weeding seedlings were taken * times. When two true leaves are grown, the second weeding and seedlings will be carried out, and the top fertilizer and water will be used. After each harvest, the water will be topdressed once and sprayed with the vegetables. This will make the amaranth seedlings flourish. The stems are thick, the leaves are thick, and the yield is high. At the end of March of the following year, when the temperature rises, the small arch shed can be removed, and a new high-fat film can be sprayed to prevent high-temperature burning seedlings and prevent white rust of amaranth.
