What kind of fertilizer does leek use to grow prosperous? can the leek planted in the first year be cut?

Leek is a very common vegetable, leek has a very high edible value, the market is very popular with consumers. At present, leek has been planted in China for a long time, but at the time of planting, there are still many people on what fertilizer it should be applied, and the specific harvesting method is not clear. Let's take a look at it together.

What kind of fertilizer does leek use to grow?

The main results are as follows: 1. Traditional fertilizer, when leek begins to grow in spring, 15kg compound fertilizer is applied per mu, after each harvest, the surrounding soil is hoed, the wound of leek is healed after 2 to 3 days, and when the new leaves are about to come out, water and topdressing are carried out. Generally, about 20 kg of compound fertilizer is applied per mu.

2. A new type of fertilizer, the balanced formula can be selected when applying water-soluble fertilizer to leek, such as 20-20-20+TE, which not only contains a lot of elements, but also contains medium and trace elements such as iron, manganese, zinc, copper, calcium, boron, molybdenum and so on.

Can you cut the leek planted in the first year?

Leeks planted in the first year can be harvested.

1. New species of leek: it can be harvested timely and appropriately according to plant growth and market situation. The leek in the big arch shed is generally harvested for three crops, the first stubble growth period is 30-40 days, the yield is relatively low, and the subsequent growth period is about 20-25 days.

2. The yield of leek in the second crop is the highest, which can be harvested early before and after the Spring Festival. The best harvest in the morning is to cut to the upper 3-4 cm yellow leaf sheath of the bulb and pack it in time while cutting to keep the leek fresh and prevent water loss from freezing injury.

Fertilization skills of leek

The main results are as follows: 1. Leek fertilization first raises seedlings in the seedling bed or seedling land, and the growth and fertilizer consumption of leek in the seedling stage is small, but because the seedlings are relatively weak, the root system is underdeveloped and the fertilizer absorption is weak, in addition to applying sufficient base fertilizer, quick-acting chemical fertilizer should be applied by stages to promote the growth and make the seedlings grow healthily. In the cool autumn season after planting, the growth rate of leek is accelerated and the growth is increased, so topdressing should be applied in time to promote the production and accumulation of nutrients. Leeks sown in that year are generally not harvested in that year.

2. When the height of leek seedlings reaches 18cm to 20cm, it should be planted. Before planting, 5000 kg of organic fertilizer was applied per mu in the planting land, spread and ploughed into the soil, and after leveling the land, the border or planting ditch was opened according to the cultivation method, and then 2000 kg / mu of high-quality organic fertilizer was applied in the border (ditch). After the fertilizer and soil are evenly mixed, it can be planted.

3. The leek in the second year of sowing has grown strong and mature, and has begun to be harvested and listed on the market. Timely supplement of nutrients taken away by harvest in winter can quickly restore the growth of leek, maintain a strong growth momentum, and prevent premature senescence caused by nutrient loss caused by harvest.

How to water leek

1. Seedling stage. Seed germination requires a large amount of water, and only when the soil water content reaches more than 70% can the water pass through the stratum corneum of the seed coat. The border surface should be kept moist before the seedlings are unearthed to prevent the soil from hardening, making it difficult for the seedlings to be unearthed. After the seedlings are unearthed, the roots are small and shallow, too much watering is easy for the seedlings to grow; too little watering is easy to harden on the ground, and the seedlings are dry. Should be gently watered frequently, always keep the ground moist, in order to promote the growth of seedlings. When the height of the seedling is 12cm to 15cm, squat the seedling under water control. Timely watering according to the wetness of the soil. If the seedlings grow strong, you can avoid topdressing to facilitate squatting and prevent seedlings from overgrowing and lodging. Pay attention to waterlogging and drainage in years with a lot of precipitation.

2. Adult plant. After transplanting, do not water before cutting head knife and leek in spring. After 3 days of harvest, the knife edge healed, waiting for the leek to grow out of the ground before watering, the amount of water was determined according to the soil moisture. The temperature condition after the Beginning of Autumn is just suitable for the growth of leek, which is a favorable time to cultivate root growth and plant sturdiness, but watering must have a good grasp of the quantity. It should be determined according to the magnitude and amount of precipitation in autumn. Because chives are afraid of waterlogging in autumn, do not water them if they are not drought. if there is too much precipitation, we must do a good job of drainage and waterlogging to prevent leeks from retting roots and rotten leaves, resulting in reduced production. Before and after the Beginning of Winter, the aboveground part of the seedling-type leek has withered, pay attention to pouring frozen water. If the autumn rain is heavy and the soil water content is high, winter irrigation is not needed.

After reading some of the introductions about leek fertilization and harvesting above, we must know more about it. The fertilization of leek varies from time to time. You must pay attention to the harvest. You can usually harvest it three times.
