First, the base fertilizer
Firstly, seedlings are raised in seedbeds or nursery fields. The growth of amaranth in seedling stage is small and the amount of fertilizer is small. However, because the seedlings are relatively weak, the roots are underdeveloped and the fertility is weak. In addition to the application of the base fertilizer, the quick-acting fertilizer should be applied in stages to promote growth. To make the seedlings grow strong. After colonization, it enters the autumn cool season, the growth rate of leeks is accelerated, and the growth is increased. It is timely to topdress to promote the manufacture and accumulation of nutrients. The leeks sowed in the same year were generally not harvested that year.
When the amaranth seedlings grow to a height of 18 to 20 cm, they are planted. Before planting, 5000 kg of organic fertilizer will be applied to the acreage in the planting area, and the application will be carried out by cultivating and ploughing into the soil. After leveling the ground, the planting method will be used as a hoe or a planting ditch, and in the sag (in the ditch), 2000 kg of high-quality organic fertilizer will be applied. After the fertilizer is mixed with the soil, it can be planted.
The second year of sowing, the amaranth has grown robustly and matured, and began to harvest. In the winter, the nutrients taken away by the harvest are replenished in time, so that the leek can quickly resume growth, maintain a strong growth momentum, and prevent the plant from premature aging due to nutrient loss caused by harvesting.
The demand for fertilizer in leek is mainly based on nitrogen fertilizer, with appropriate amount of phosphorus and potassium fertilizer. Only the nitrogen fertilizer is sufficient for the leaves to be fat and tender, and the nitrogen uptake is higher than other vegetables, but the excessive nitrogen is likely to cause the leek to fall. The addition of potassium fertilizer can promote cell division and expansion, accelerate the synthesis and operation of sugar; the application of sufficient amount of phosphate fertilizer can promote the absorption of nitrogen fertilizer by plants and improve product quality. In addition, the application of organic fertilizer can improve the soil, improve soil permeability, promote root growth and improve quality.
