About leek fertilization problem, has written a lot before, but at present is the autumn harvest season of leek, here and everyone to talk about leek fertilization problem.

How to fertilize leeks more productively?

First of all, we need to look at the fertilizer requirements of leeks. The growth of leeks is relatively fast, and the number of harvests is relatively frequent, so the fertilizer requirements of leeks are relatively large. At ordinary times, we should pay attention to the fertilization of leeks. The seedling stage of leek needs less fertilizer, but the fertilizer requirement of leek for two or three years is relatively large. At this time, leek is in the vigorous stage of growth, requiring large amount of fertilizer and growing well. The leek that grows for more than 5 years enters the old stage of leek. At this time, the growth trend of leek is not good. If it continues to be planted, it is necessary to increase the application of fertilizer. In addition, leek in the growth process of nitrogen absorption most, but also with the use of phosphorus and potassium.

At present, it is autumn, leek enters the production peak season, this time leek harvest is more, so more attention should be paid to the problem of fertilization. Let me start by talking about how to fertilize leeks in autumn.

Autumn this period of time climate is suitable, pests and diseases reduced, and after a summer root, this period of time the leek growth trend is the most prosperous. However, if the problem of fertilization should also be paid attention to, fertilization must pay attention to grasp the time, fertilization too early, easy to cause leek excessive growth, leading to lodging and disease occurrence probability increased. Fertilization too late is not conducive to the late growth of leek.

In autumn, topdressing is generally required two to three times, and fertilizer is usually applied at an interval of about 20 days from the beginning of September. Generally, about 15 kg of ammonium sulfate is used per mu of leek field. In addition, it is this time to harvest leek shares, harvest after three days or so to apply fertilizer, generally with watering fertilizer.

After autumn fertilization, we will explain the fertilization of leek according to different species. Chives are not only planted in the field, but many friends also like to plant a few pots of chives at home. It is much easier to plant chives in the family than in the field.

Let's start by talking about how to fertilize family leeks.

Family planting leek is also inseparable from fertilizer, first of all is the base fertilizer problem, because the planting place is relatively limited, generally in the bottom of the flowerpot some decomposed chicken manure can be. After transplanting, the leek should be top-dressed. During this time, the fertilizer should not be too thick, but light fertilizer can be applied. It can be applied once every other week, and some decomposed cake fertilizer can be applied. When the leek grows to be harvested, topdressing should be carried out every time the leek is harvested. Topdressing is generally carried out three days after harvesting. Some decomposed organic fertilizer can be applied.

Let's take a look at how the leek planted in the field is fertilized.

First of all, the amount to be said is also the problem of base fertilizer. The base fertilizer of leek is related to the growth of leek in the later stage. Generally, the base fertilizer is mainly organic fertilizer, and about 5000 kg organic fertilizer can be applied per mu. In addition, leek topdressing problem, leek topdressing generally has knife fertilizer said, that is to say every leek harvest after timely topdressing. Topdressing is carried out two or three days after each harvest, and ammonium sulfate is applied about 15 kg each time, and irrigation is carried out.

In addition, summer leek enters dormant period, this time is not suitable for harvesting leek, need leek rest root cultivation. This period of time can be applied to leek about 15 kg of ammonium sulfate per mu, so that leek smooth summer.
