How to fertilize chives for high yield? The latest technical tutorial teaches you
Chives are one of the vegetables with relatively large market demand, and the market price is stable. In addition, they are a perennial vegetable that can be harvested several times a year. Growing chives brings farmers considerable economic income. But if you want chives to grow fast and well, fertilization is an extremely important task. Mastering the timing and methods of fertilizing chives is the prerequisite for achieving high yield. So how should you fertilize? Let's take a look together with Qinnong.com.
1. Apply enough base fertilizer
When chives are seedlings, their growth amount is small, and their demand for and consumption of fertility are relatively small. Moreover, the seedlings are relatively weak, the root system has not yet fully developed, and the absorption of fertility is weak. Therefore, at this time, in addition to applying enough base fertilizer, some quick-acting chemical fertilizer should also be applied as a top dressing to make them grow quickly and speed up root growth. However, when chives grow to about 20cm, they can be planted. Enough organic fertilizer should be applied in the planting field. After spreading the fertilizer into the soil, deep plow and mix evenly, then level and make beds before planting. After they grow to maturity in the second year, they can be harvested and sold. At this time, fertilization is needed once more to help the chives recover quickly and avoid premature aging caused by nutrient loss after harvest.

After chives are planted, after the hot summer, they enter the cool autumn. At this time, the temperature is most suitable for the growth of chives, and it is also the most critical period for fertilizer and water management. Timely fertilization and maintaining nutrient supply are the foundation for whether chives can grow quickly. In addition, when chives overwinter, it depends on the accumulation of nutrients, and autumn is sometimes the stage of nutrient accumulation, so fertilizer and water management at this time is particularly important. During this period, top dressing is generally applied 2-3 times, usually once in early September, once in late September, and once in early October. When top dressing, generally about 15-20 kg of ammonium sulfate per mu. Three days after chives are harvested, new leaves begin to grow slowly. At this time, ammonium sulfate should also be applied once together with watering, in the same amount as before. Be sure to water and fertilize 2-3 days after harvest to avoid root rot. Chives are not harvested when overwintering in summer. Summer chives have more fibrous tissue and a poorer taste. At this time, fertilizer is also needed once to help them safely pass the summer, with the same fertilizer and dosage.
3. Skillfully apply plant ash
Skillfully applying some plant ash during planting can play an increasing role. During the growth stage of chives, applying some plant ash, which is a good water-soluble quick-acting potassium fertilizer, can make chives root and tiller as quickly as possible, with an obvious yield-increasing effect. In addition, many chives are now grown in greenhouses, and gray mold is prone to occur during greenhouse cultivation, causing losses. Applying plant ash can reduce the incidence of this disease. When top dressing, a large amount of ammonium sulfate is applied. Ammonium sulfate is an acid fertilizer. Long-term application acidifies the soil and easily causes yellow leaves and death of chives, while plant ash is an alkaline fertilizer and can regulate the pH of the soil, allowing chives to grow normally.
