How many days after planting various vegetables can you fertilize?

Leafy vegetables can be fertilized a week after planting, because leafy vegetables have high requirements for soil fast-acting nutrients and are more sensitive, if there is a lack of nutrients, there will be a slowdown in leaf growth, and the leaves will turn yellow, so in the leafy vegetables to be topdressed in time, every 15-30 days you need to apply farmhouse fertilizer.

When nightshade vegetables have grown to 3-4 leaves, they can be fertilized. In the seedling stage, more nitrogen fertilizer is needed, but too much nitrogen fertilizer will cause the plant to grow, so pay attention to the amount of nitrogen fertilizer. After entering the growth period, the demand for phosphate fertilizer of nightshade vegetables increases, so it is necessary to reduce the application of nitrogen fertilizer and focus on increasing the application of phosphorus fertilizer and potassium fertilizer.

When the fruit is done, it needs to be supplemented with fertilizer water after each harvest.

When the root vegetables grow to 4-5 cm, they can be fertilized for the first time. It needs to be fertilized with more nitrogen fertilizer in the early stages of its growth, as this can promote the growth of leaves. Potassium fertilizer needs to be applied in the middle and late stages of growth, and the amount of nitrogen fertilizer needs to be properly controlled at this time, because too much nitrogen fertilizer in the later stage will lead to the growth of vegetables, the yield will decrease, and the quality will deteriorate.

When fertilizing, you need to pay attention to the fertilizer should be far away from the roots, otherwise root burns are likely to occur.

phenomenon. If there are enough nutrients in the soil, you need to reduce the number of fertilizations.

Vegetables can be fertilized 7-10 days after emergence, because the root system is relatively weak, so it is recommended to use some rooting and strong seedlings to fertilize to promote the growth of vegetable roots and improve growth. Fertilizer can be divided into base fertilizer, seed fertilizer and top dressing according to different application periods, application purposes and methods.

Generally, you can fertilize two or three days after planting, because if you plant it, let him sprout first, and the sprout is to absorb its own nutrients, and after the sprout, you can irrigate it through the nutrients in the fertilizer, so that it can also grow.

1. Leafy vegetables: Leafy vegetables mainly include cabbage, greens, spinach, amaranth, etc. Nitrogen fertilizer is the main topdressing of leafy vegetables, but phosphorus and potassium fertilizers need to be applied at the same time as nitrogen fertilizer in the peak growth period.

When the vegetables begin to enter the rosette stage and before the heart, fertilization should be carried out. 2. Fruits and vegetables: fruits and vegetables include melons, eggplant fruits and beans, and generally seedlings need more nitrogen fertilizer, but excessive application of nitrogen fertilizer is easy to cause growth, but prolongs flowering and fruiting, resulting in flower and fruit drop; In the human reproductive growth period, the amount of phosphorus fertilizer required increased sharply, and the amount of nitrogen fertilizer required decreased slightly, so it was necessary to increase the application of phosphorus and potassium fertilizer and control the amount of nitrogen fertilizer.

After the cucumber sits on the melon, it should be refertilized, and water needs to be replenished once for each batch of melons. 3. Root vegetables: root vegetables mainly include radish, carrots, etc., and the edible part is fleshy roots.

In the early stage of root vegetable growth, more nitrogen fertilizer should be applied to promote the formation of hypertrophic green leaves; In the middle and late stages of growth, more potassium fertilizer should be applied, and the amount of nitrogen fertilizer should be properly controlled, so as to promote the transport of assimilated substances from the leaves to the roots, so as to form strong fleshy roots.

Summary. Dear, I'm honored to have your question The information that the teacher found for you here is: How many days can you fertilize all kinds of vegetables after planting?

All kinds of vegetables can be fertilized 7 days after planting. In general, the fertilization management of vegetables at the seedling stage is similar. After 7 days of planting, the seedlings can be fertilized with water.

At this time, it is not allowed to use a large number of elements, under normal circumstances, you can rush amino acids, humic acids, algae extract, microbial agents and other rooting fertilizers to promote root growth. The seedling stage has just slowed down, and the root system is very weak, so using a large number of elements will not only cause loss and waste, but also damage the roots if used excessively. At this time, the root system can not absorb so many nutrients, and the application of a large number of elements is easy to cause vigorous growth in the seedling stage, which is very unfavorable to the later flowering and fruit setting.

Generally, when planting vegetables, a certain amount of organic fertilizer and a small amount of compound fertilizer will be added when using base fertilizer. For planting with over-used base fertilizer, it is generally best to start using a large number of elements after flowering and fruit set. If you do not use base fertilizer for planting, you can apply a small amount of balanced macro-element water-soluble fertilizer before flowering, 3-5 kg per acre, which can provide sufficient nutrients for the flowering period.

Summary. Hello dear, vegetables can be eaten 1-2 days after fertilization, vegetable products fertilization should choose the right fertilizer, in different stages of production to apply different fertilizers, vegetable fertilizer in the early stage of two kinds, one is base fertilizer, the other is top dressing, vegetable seedling base fertilizer. When vegetables are sown, the general base fertilizer is suitable for using farmhouse organic fertilizer.

Vegetables can be eaten after fertilizing for a few days.

Extended information: Vegetables have high nutritional value, generally rich in crude fiber, vitamins, minerals and other nutrients, vegetables can supplement the nutrients needed by the body, and can maintain the normal life activities of the human body to a certain extent. Since vegetables contain more crude fiber, moderate consumption of vegetables can promote intestinal peristalsis, and have a certain effect on improving indigestion and constipation.

Vegetable fertilization is usually applied once a week with liquid fertilizer and more than half a month with manure. The frequency of fertilization should not be too frequent, which can easily lead to excess nutrients. Fertilization also needs to be decided according to the variety of vegetables grown.

Different varieties have different types of fertilization and methods. It is also necessary to adjust the frequency of fertilization according to the growth of vegetables, and keep the fertilizer away from the roots when applying fertilizer to prevent burns.

If you want to grow vegetables at home, it is best to figure it out first when you grow vegetables for a few days and fertilize them. In most cases, liquid manure can be applied once a week, and then manure can be applied every six months to a month or so. Try to stay away from the roots when fertilizing, otherwise it is easy to burn.

If there are enough nutrients in the soil, the frequency of fertilization needs to be reduced.

Planting vegetables and fertilizing also depends on the variety of vegetables, if it is similar to cabbage, greens, lettuce and other leafy vegetables. Generally, nitrogen fertilizer is mainly applied during the peak growth period, not too frequently, and a small amount of potassium fertilizer and phosphate fertilizer are added at the same time. Replenish adequate nutrients.

When planting fruits and vegetables, including beans, melons and fruits, etc., the general edible part is the fruit of vegetables, so it is necessary to apply enough nitrogen fertilizer at the seedling stage, and the amount can not be too much, which can easily lead to growth delay. Causes flower buds to fall.

When planting root vegetables such as radish vegetables, the edible part is grown in the soil, so more nitrogen fertilizer needs to be applied in the early stage of growth to promote the growth of leaves; In the middle and late stages, the amount of nitrogen fertilizer can be reduced and potassium fertilizer can be increased, so that the roots can absorb enough nutrients.

Many people will grow some vegetables for their own family to eat, and if you want the vegetables to grow delicious, fertilization is very important. Many people don't know how long to fertilize, so how many days to fertilize vegetables?

Depending on the fertilizer used, the time between planting and fertilizing varies greatly. If it is liquid fertilizer applied, then it can be done once a week; If it is the manure of livestock at home, it can be fertilized every 20 days or half a month or so. At the same time, it is necessary to fertilize according to the growth of vegetables, if the growth state is better, it means that there are still certain nutrients in the soil, and you don't need to fertilize it first.

When applying fertilizer, it should be applied in small amounts, and not excessive fertilizer. In fact, the range of fertilizers used in vegetables is very wide, in fact, the soil itself contains many kinds of fertilizers, just like people need to supplement protein, vegetables need to supplement basic elements such as nitrogen, phosphorus, potassium and so on.

The number of days of fertilization depends mainly on the fertilizer used, and the interval between different fertilizers varies greatly, generally every 20 days or about half a month, and it is best to apply it reasonably.
