Chives want to grow well, knife topdressing is very important, summer seedlings can not be less.

Leek has always been my favorite vegetable, and my favorite food is dumplings filled with leeks and eggs. Apart from eating leeks, you may not know that leeks have another use, that is, to watch leeks as potted plants. There is a poem saying in the ancients, "gradually feeling the extreme cold of Dongfeng materials, Artemisia annua and yellow leeks try spring dishes." Today I will talk to you about how to fertilize leeks.

Growth habits of Chinese chives

The first step to fertilize leeks is to understand the growth habits of leeks, although it is a clich é, but there are still many friends ignore this point. Leek belongs to perennial root plant, which can be planted in most parts of our country, which is not only cold-resistant but also heat-resistant. If planted in the south, it can be harvested all the year round, while in the north it is evergreen for three seasons. The most suitable growth temperature is about 25 degrees, shade-resistant and moderate light. The soil likes slightly acidic soil with strong fertility.

Fertilization of leek

There are many ways to apply fertilizer, but targeted fertilization should be carried out, taking into account your planting method and the characteristics of the planting environment, so that the leek can grow well enough. Here is divided into many aspects to introduce the main points of leek fertilization.

First of all, let's introduce how to fertilize leek grown at home.

Now many families will choose to grow some vegetables at home, leek is a good choice, the four seasons can eat, but also can eat for many years. The leek planted in the family is not like the leek planted on the ground. The leek planted in the family is generally planted in the flowerpot, so we should pay more attention to the problem of fertilization.

First of all, put enough base fertilizer in the flowerpot before planting, which can choose rotten chicken manure, or rotten soybean meal, egg shell, bone meal and so on. It should be noted that the base fertilizer should be put into the bottom of the flowerpot to prevent root burning.

After the leek survived, topdressing should be carried out, because the leek likes to be fat, so we should pay attention to topdressing in time. Generally every other week can be applied fertilizer, you can apply some mature diluted cake fertilizer, pay attention to be diluted. Wait until the leek enters the normal growth period, every harvest of leek, it is necessary to fertilize in time, especially in the spring and autumn.

In fact, people's urine and dung is the most suitable for leeks, not enough smell is not good. So at ordinary times, you can collect the food waste and mature it as fertilizer. If you can't, you can also buy some special fertilizers in the flower market.

Fertilization for planting leek in the field

Base fertilizer

The fertilization of leek planted in the field is much more troublesome than that of family planting. It is very important for leek to have a high yield. Here are some fertilization techniques to share with you.

First of all, it is the base fertilizer, which must be sufficient. Generally, 5000 kg of organic fertilizer per mu is used for soil preparation before planting. After soil preparation, about 2000 kg of organic fertilizer and soil need to be mixed into the ditch. When the leek planting after the end of the slow seedling stage should be timely topdressing, topdressing is generally the use of urea or diammonium phosphate, the amount is generally about 20 kg per mu. Leek is not harvested in the same year and can only be harvested the next year.

Topdressing

Because leek is often harvested and consumes a lot of nutrients, it is necessary to apply fertilizer in time after each harvest to prevent root damage and premature senescence. Generally, topdressing is carried out about three days after harvest, and be careful not to water it in a hurry, which is prone to root rot. Mainly apply some phosphorus and potassium fertilizer and nitrogen fertilizer to promote root growth. Generally, about 20 kg of ammonium sulfate compound fertilizer is used per mu. You can also use mature diluted human urine manure (about 400 kg per mu) mixed compound fertilizer (about 30 kg) into the leek field.

In addition, pay attention to the summer leek need to stop seedlings, topdressing can be appropriately reduced, generally can be applied ammonium sulfate in rainy days.

The above comes from promoting agriculture through science.
