Fertilization technology of leek : 1. Base fertilizer. On the basis of the application of organic fertilizer, 25 to 30 kg of phosphate and potassium phosphate fertilizer per acre . 2. Topdressing. In the autumn, the topdressing is generally twice. The first time is to chase the Tianji brand of NPK fertilizer 30 to 35 kg, the second time to chase the Tianji brand of NPK 20 kg, and apply an organic fertilizer before wintering. Spring fertilization should be combined with organic fertilizer to chase the Tianji brand of NPK fertilizer 20 ~ 30 kg, in order to return to green, each harvest, per acre to apply Tianji brand nitrate and potassium fertilizer 30 ~ 35 kg.

Amaranth is a family of Liliaceae, which is widely cultivated all over the country. It is rich in vitamins, minerals, carbohydrates and protein.
Amaranth grows from seed germination to flower bud differentiation, which is the growth period of roots, stems and leaves. It is divided into germination stage, seedling stage, vegetative growth period and wintering dormancy period. From flower bud differentiation to pollination and fertilization, the seed matures and is the reproductive growth stage of amaranth. This period is divided into flower bud differentiation stage, convulsion flowering stage and seed development stage.
The fertilizer requirement of amaranth is: the growth amount and the amount of fertilizer consumed in the seedling stage are small, but the vegetative growth period, especially in the spring and autumn harvest season, the growth amount and the amount of fertilizer required, should be fertilized in large quantities. The 2 to 4 year old leek grows vigorously, has strong tillering ability, high yield, and requires the largest amount of fertilizer, which is the peak of fertilizer demand. Amaranth, which is more than 5 years old, gradually enters the aging stage. In order to prevent premature aging, it is necessary to strengthen fertilization.
