Wild amaranth cultivation techniques

Select sandy loamy soil or clay loam with flat terrain, convenient drainage and irrigation, and fertile and loose soil, and prefer alkaline soil. Generally, direct seedling is used, and seedlings are rarely transplanted to harvest seedlings for food. Sowing in early spring from March to March, mostly using greenhouses and small arch shed cultivation; spring planting (from April to May), multiple sets of seeds are planted under melons, eggplants and beans, or mixed with other green leafy vegetables, seeded in stages, successively Harvest. Before planting, turn the vegetable field deep and lime it, 150 kg per 666.7 square meters. When preparing the land, the manure and animal manure are used as the base fertilizer. About 66,500 square meters of spring planters are used for spring sowing, 1,500 kg for summer sowing, and 2,000 kg for autumn sowing. The surface of the concrete surface is thin and flat, and the deep trench should be high, and the width of the concrete should be 1.2-1.5 meters. The seeding amount is 0.5-0.75 kg per 666.7 square meters, the seeding period is too early, and the seeding amount is slightly larger. After sowing, do not cover soil or thin soil, or cover with fine sand or plant ash or human or animal dung. Instead of mulching, town soil can also be used. After sowing, the weather and soil were watered and fertilized after seeding, and emerged in about 10 days. In spring, the temperature is low and there is a lot of water. Generally, watering should be controlled. Watering is often performed only in high temperature or drought. The growth of amaranth is sunny or not, as the saying goes: "a sunny day, rainy day's amaranth" is what this means. From the time of sowing to the growth of 2 true leaves, choose the sunny day for the top dressing; after about 12 days, carry out the second dressing, after the third batch of dressing, perform the third dressing, and then pick up the top dressing every time. once. Topdressing is mainly based on quick-acting nitrogen fertilizer, and about 10 kg of urea or 2-3 per cent of rotten cooked human urine is applied every 666.7 square meters. And timely remove field weeds.

Sowing amaranth in summer and autumn only takes 3-5 days to emerge. After emergence, weeding should be timely, and water and fertilizer management should be strengthened to keep the soil moist. In the mid-summer high temperature period, it is also necessary to cover the shading net to cool and moisturize, so that it can be covered day and night, and create a suitable temperature environment that is conducive to the growth of amaranth, and is conducive to increasing yield and improving quality. Harvest in time when the plant is about 15 cm in height (can be pulled up or harvested at one time). In the first 15 days before harvesting, 2-3% of the manure of rotten mature people can be applied. In the later stage, the top-up fertilizer is mainly available with quick-acting nitrogen fertilizer and watered in time. Otherwise, it blooms quickly and affects quality and yield.

Amaranth stem is the main stalk of amaranth, commonly known as old amaranth. Planting amaranth is to provide raw materials for making mold mustard. In order to obtain a stout main stem, a special green-green amaranth stalk with thick leaves and hairy stalks should be used; the seedlings should be transplanted and planted at a row spacing of 20 × 20 cm. green. As amaranth stalks are sporadically planted in many places, there is no documented data clearly reporting suitable varieties for amaranth stalks.
