How to fertilize chives for high yield? Key practical fertilization techniques
Chives are one of the vegetables with relatively high market demand, and their market price is stable. In addition, they are a perennial vegetable that can be harvested several times a year, and growing chives brings farmers substantial economic income. However, if you want chives to grow quickly 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, their demand for and consumption of nutrients is relatively low, and the seedlings are relatively weak, with root growth not yet fully developed, so their nutrient absorption 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 promote rapid growth and accelerate root growth. However, when chives grow to about 20 cm, they can be transplanted. Enough organic fertilizer should be applied in the transplanting field. After spreading the fertilizer into the soil, plow deeply and mix it evenly, then level and make beds before transplanting. After they grow to maturity in the second year, they can be harvested for market. At this time, fertilizer needs to be applied once more so that the chives recover quickly and avoid premature aging caused by nutrient loss after harvesting.
2. Apply top dressing in time
After chives are transplanted, after the hot summer passes and they enter the cool autumn, the temperature at this time is most suitable for chive growth, and it is also the most critical period for fertilizer and water management. Applying fertilizer in time and maintaining nutrient supply is the foundation for whether chives can grow quickly. In addition, whether chives overwinter depends on nutrient accumulation, 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. For top dressing, generally about 15-20 kg of ammonium sulfate per mu is used. 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 harvesting to avoid root rot. Chives are not harvested when overwintering through summer. Summer chives have more fibrous tissue and a poorer taste. At this time, fertilizer also needs to be applied 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 help chives take 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 in greenhouse cultivation, causing losses, while applying plant ash can reduce the incidence of this disease. During top dressing, a large amount of ammonium sulfate is applied. Ammonium sulfate is an acid fertilizer, and long-term application acidifies the soil, which easily leads to yellow leaves and death of chives, while plant ash is an alkaline fertilizer and can regulate the pH of the soil so that chives grow normally.
