How should fertilizer be applied when growing Chinese chives? Please explain how best to fertilize Chinese chives. Please explain the method.From seed germination to flower bud differentiation, Chinese chives are in the vegetative growth period. During this period, the roots, stems and leaves mainly grow, and it is further divided into the germination period, seedling period, peak vegetative growth period and overwintering dormant period. From the beginning of flower bud differentiation to seed development and maturity after pollination and fertilization, Chinese chives are in the reproductive growth period, which is further divided into the flower bud differentiation period, bolting and flowering period, and seed development and maturity period. Fertilizing Chinese chives can refer to the following methods:
The fertilizer requirements of Chinese chives are as follows: during the seedling period, the amount of growth and fertilizer consumption are relatively small, but during the peak vegetative growth period, especially in the spring and autumn harvest seasons, the amount of growth and fertilizer demand are large, so large amounts of fertilizer should be applied in stages. Chinese chives 2 to 4 years old grow vigorously, have strong tillering ability and high yield, and have the greatest fertilizer demand, making this the peak period of fertilizer need. Chinese chives over 5 years old gradually enter the aging stage. To prevent premature aging, fertilization needs to be strengthened.
Fertilization techniques for Chinese chives:
1. Base fertilizer for Chinese chives: generally, on the basis of applying sufficient organic fertilizer, apply 25 to 30 kg of Tianji brand phosphorus potassium phosphate fertilizer per mu.
2. Topdressing for Chinese chives: Chinese chives are generally topdressed twice in autumn. For the first time, apply 30 to 35 kg of Tianji brand nitrate phosphorus potassium fertilizer per mu; for the second time, apply 20 kg of Tianji brand nitrate phosphorus potassium fertilizer per mu. At the same time, apply sufficient organic fertilizer once more before overwintering. In spring, fertilization should be combined with organic fertilizer, applying 20 to 30 kg of Tianji brand nitrate phosphorus potassium fertilizer per mu to promote greening. After each harvest, apply 30 to 35 kg of Tianji brand nitrate phosphorus potassium fertilizer per mu.
