What fertilizer makes chives grow vigorously, and can chives planted in the first year be cut?
Chives are a very common vegetable, and chives have very high edible value, and are very popular among consumers on the market. At present, chives have been cultivated in China for a very long time, but when planting them, many people are still unclear about what fertilizer is best to apply to them, and the specific harvesting method is not clear either. Let's take a look below!
What fertilizer makes chives grow vigorously
1. Traditional fertilizer: in spring, when chives begin to grow, apply 15-20 kg of compound fertilizer per mu as a top dressing. After entering the harvest period, after each cutting, loosen the surrounding soil with a hoe, and after 2-3 days, once the chive wounds have healed and new leaves are about to emerge, water and apply top dressing, generally applying about 20 kg of compound fertilizer per mu.
2. New-type fertilizer: when applying water-soluble fertilizer to chives, a balanced formula type can be chosen, such as Moore water-soluble fertilizer 20-20-20+TE, which besides containing major elements also contains secondary and trace elements such as iron, manganese, zinc, copper, calcium, boron, molybdenum, and so on.
Can chives planted in the first year be cut
Chives planted in the first year can be harvested.
1. Newly planted chives: they can be harvested at the appropriate time and in the appropriate amount according to plant growth and market conditions. Chives in large arched sheds are generally harvested three times; the first crop has a growth period of 30-40 days and a relatively low yield, after which each crop only needs a growth period of about 20-25 days.
2. The second crop of chives has the highest yield, and when it coincides with around the Spring Festival it can be harvested appropriately earlier. Harvesting in the morning is best, and it is advisable to cut down to the yellow leaf sheath 3-4 cm above the bulb; cut and bundle at the same time, and package promptly to keep the chives fresh and prevent water loss and frost damage.
Fertilization techniques for chives
1. For fertilizing chives, first raise seedlings in a seedbed or seedling nursery. During the seedling stage, chives grow little and consume little fertilizer, but because the seedlings are relatively weak, with underdeveloped root systems and weak fertilizer uptake, in addition to applying enough base fertilizer, quick-acting chemical fertilizer should also be applied as a top dressing in stages to promote growth and make the seedlings grow robustly. After planting, when the cool autumn season arrives, chives grow faster and the amount of growth increases, so top dressing should be applied in time to promote the production and accumulation of nutrients. Chives sown in the current year are generally not harvested in that same year.
2. When chive seedlings have grown to 18-20 cm tall, transplant them. Before transplanting, apply 5,000 kg of organic fertilizer per mu in the transplanting field, broadcast it, plow it into the soil, level the land, and then make beds or open transplanting furrows according to the cultivation method; then apply 2,000 kg/mu of high-quality organic fertilizer in the beds (furrows), and after the fertilizer is mixed evenly with the soil, transplanting can be done.
3. Chives in the second year after sowing have already grown robustly and reached maturity, and begin to be harvested for market. In winter, promptly replenish the nutrients taken away by harvesting, so that chives quickly recover growth, maintain vigorous growth momentum, and prevent premature aging of the plants caused by nutrient loss from harvesting.
How to water chives
1. Seedling stage. Seed germination requires a large amount of water, and only when the soil moisture content reaches above 70% can water pass through the cuticle layer of the seed coat. Before the seedlings emerge, the bed surface should be kept moist to prevent the soil surface from crusting, which would make it difficult for the seedlings to emerge. After the seedlings emerge, the roots are small and shallow; too much watering makes the seedlings prone to excessive vegetative growth, while too little watering makes the ground prone to crusting and the seedlings prone to drying up. Water lightly and frequently, and always keep the ground moist to promote seedling growth. When the seedlings are 12-15 cm tall, control water to harden the seedlings. Water in time according to soil moisture conditions. If the seedlings grow robustly, top dressing may be omitted to facilitate seedling hardening and prevent excessive growth and lodging of the seedlings. In years with heavy rainfall, pay attention to waterlogging prevention and drainage.
2. Adult plants. After transplanting, do not water in spring before cutting the first crop of chives. Three days after harvesting, once the cut has healed, water again after the chives have sprouted above ground; the amount of water depends on soil moisture. The temperature conditions after the Start of Autumn are just right for chive growth, and this is a favorable time for cultivating root growth and making the plants sturdy, but the amount of watering must be well controlled. It should be decided according to the amount and frequency of autumn rainfall. This is because chives are afraid of waterlogging in autumn; do not water unless there is drought, and if there is too much rain, be sure to do a good job of drainage and waterlogging prevention to prevent chive root rot and leaf rot, which would cause reduced yield. Around the Start of Winter, the aboveground part of fall-returning chives has already died; pay attention to watering the frozen-water irrigation. If autumn rain is heavy and soil moisture content is high, winter irrigation may also be omitted.
After reading the above introduction about fertilizing and harvesting chives, everyone must have a deeper understanding of them. When fertilizing chives, it varies depending on the period. When harvesting, be sure to pay attention; generally they can be harvested three times.
