What fertilizer is good for vegetable seedlings? How do I fertilize it?

In the process of planting vegetables, it is necessary to pay attention to the seedling stage of crops, which is a very important link. If the crop seedlings can grow well, many pests and diseases can be avoided, and the quality and yield of vegetables can be guaranteed. Vegetables can be used as compound fertilizers at the seedling stage.

To increase the nutrition of seedlings, you need to pay attention to the position in the process of sprinkling chemical fertilizer, and you can't sprinkle it in the heart leaves of seedlings, otherwise it will cause seedling burning. If you want to apply basal fertilizer to seedlings, you need to pay attention to the amount of fertilizer, which must be sufficient.

In the process of top dressing, it can be cultivated in combination with watering, which can make the seedlings get better nutrition. When people choose fertilizer, they can choose commercial organic fertilizer, rice husk manure, compound fertilizer, trace element fertilizer and chicken manure, the more adequate the nutrition of fertilizer, the better the seedlings will grow. When vegetables are in the seedling period, you can use less nitrogen-rich and phosphorus-rich elements.

and potassium.

of fertilizers. When vegetables are planted, the chemical or organic fertilizers are broken down by the soil and the vegetables can get nutrients from the soil.

When the roots of vegetables obtain nutrients, they cannot be fertilized with water, otherwise a large amount of nutrients will accumulate in the roots of vegetables, and they will not be absorbed by the roots, and the roots will flow backwards. If too much nitrogen fertilizer is used during the seedling period, the seedlings may grow too vigorously and the jointing of the plant will be too high. The shallow position of the roots can lead to poor flower bud differentiation, which can have some serious consequences and delay the flowering time.

The growth of vegetables will be affected by weather factors, and when the growth of vegetables is restricted by the environment, suitable fertilizers can be applied to vegetables. The growth of vegetables is inseparable from the help of fertilizers, in which some organic fertilizers and microbial agents can be applied. Microbial agents can increase the permeability of the soil, and at the same time, it can loosen the soil, which can prevent disasters to a certain extent.

Microbial inoculants can reduce harmful bacteria in the soil, increase the number of beneficial bacteria in the soil, increase the resistance of vegetables, and maximize the use of fertilizers.

Compound fertilizer; In the process of fertilization, try to combine fertilizer and water to avoid sprinkling on the leaves, which will cause the phenomenon of burning seedlings.

Be sure to choose well-rotted farmhouse fertilizer or organic fertilizer, such fertility is very good, and it is not easy to produce poison, to grasp the time of fertilization, but also to water in time.

It is best to choose compound fertilizer, so that trace elements can be replenished in time, and also pay attention to the decomposition of microorganisms, which can properly loosen the soil.

Generally, when crops are grown, they are divided into vegetative growth stage and reproductive growth stage. During vegetative growth, it is mainly the growth of roots, stems, and leaves, while the growth of flowers, fruits, and fruits belongs to reproductive growth. In all plants, vegetables will also go through these two periods, in general, vegetables belong to the stage of vegetative growth after seed germination to flowering, so in the early stage of fertilization, mainly nitrogen fertilizer.

In the early stage of vegetables, you can apply some base fertilizer, which is the case of base fertilizer is generally farm fertilizer, organic fertilizer, etc., such as rotten and fermented animal manure and human manure, etc., you can also use artificial mixed fertilizer, but this fertilizer will increase the cost of vegetable farmers to grow vegetables, most people will still use farm fertilizer when applying base fertilizer.

Since the seedlings that grow after the germination of vegetable seeds are very tender and small, it is necessary to pay attention to the amount of top dressing. Avoid too much fertilizer causing seedlings to burn. After the emergence of vegetables, only a relatively small amount of nitrogen fertilizer can be applied within a month, and the concentration can not be too high to prevent the vaccine from burning and dying, and some nitrogen fertilizer with a higher concentration can be applied after 30 days.

When the vegetables are still seedlings, the seedlings are very weak, so it is also very necessary to choose some fungal agents.

Organic fertilizer can provide crops with the nutrients they need, so this microbial agent can also increase the air permeability of the soil, play a role in loosening the soil, prevent the soil from compacting and clumping, and also prevent the root system of vegetables from developing diseases. However, it must be noted that the farmhouse fertilizer must be prepared sufficiently, because if the farmhouse fertilizer is chosen to be used, it must be fully rotted and fermented, otherwise it will affect the absorption of vegetables into the farmhouse fertilizer. Do not sprinkle fertilizer in the center of the leaf when fertilizing, which will also cause burning seedlings and be sure to water some water to dilute it after fertilization, so that the nutrients of the fertilizer can be gathered in the roots of the vegetables, which will absorb more thoroughly.

Vegetable seedlings can be applied compound fertilizer, the use of attention to pay, can not be sprinkled in the seedlings of the heart of the leaf, to avoid causing burning seedlings, each time top dressing as far as possible combined with watering.

In the process of planting vegetables, the fertilizer applied to different types of vegetables is different, and the seedlings generally use farmhouse fertilizer as much as possible. This is good for growth.

You can add chicken manure, such a fertilizer is particularly delicious and nutritious. It was possible to do it once every two weeks, which was nice.

1. Choose the place and the type of vegetables you will grow.

2. Loosen the soil before sowing.

3. Apply basal fertilizer, which should be put into the soil substrate in advance before vegetable planting.

4. Sprinkle the seeds on top of the soil first, then gently cover with soil.

5. Water vegetables properly.

6. Top dressing, that is, fertilization in the process of vegetable growth, can be fertilized normally when the vegetables are not very big, loosen the soil at the root of the vegetable, sprinkle fertilizer, and then cover the soil.

1. Leafy vegetables: short-term leafy vegetables such as lettuce, cabbage, water spinach, etc., have weak root absorption, and eat fresh and tender stems and leaves, and require more nitrogen. And do not sprinkle chemical fertilizer in the heart leaves, so as not to cause seedlings to burn, it is best to combine watering each top dressing.

These vegetables have more fruits, high yields, longer harvest periods, and larger fertilizer requirements. However, it is also necessary to grasp the principle of thin application and diligent application at the seedling stage, and appropriately increase the amount of top dressing each time to meet the nutrients required in the vigorous fruiting period, so that the plant grows robust and prevents overgrowth. In particular, tomatoes, if there is too much nitrogen fertilizer at the seedling stage, the growth is delicate, and it is easy to be infected with diseases.

In recent years, many farmers will choose to grow their own vegetables to meet the needs of family diet, planting vegetables need to do a good job of management measures, such as fertilization is a very important work, the following is a detailed understanding of leafy vegetables, eggplant vegetables, root vegetables and precautions.

1.Leafy vegetables leafy vegetables can be fertilized a week after planting, because leafy vegetables have high requirements for soil quick-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.

2.Nightshade vegetablesWhen nightshade vegetables grow 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.

3.Root vegetablesWhen the root vegetables grow to 4-5 cm, you can apply fertilizer for the first time. It needs to be fertilized with more nitrogen fertilizer in the early stage of growth, as this can promote the growth of the 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.

4.Precautions When fertilizing, you need to pay attention to the fertilizer should be far away from the roots, otherwise it is easy to cause root burns. If there are enough nutrients in the soil, you need to reduce the number of fertilizations.

For plots with soil pH less than 5 in vegetable plots, 50-100 kg of quicklime or 50-100 kg of soil conditioner should be sprinkled per mu one week before planting to increase soil pH and supplement calcium. When the symptoms of molybdenum deficiency appear in the middle and late stages of vegetable growth, foliar spraying with ammonium molybdate aqueous solution (can also be mixed with pesticides), sprayed once every 5-6 days, sprayed twice.

(1) Uncooked farmhouse fertilizer and cake fertilizer should not be used directly.

Unrotted farm manure and cake manure contain a variety of insect eggs, germs, and will also produce a large amount of carbon dioxide and heat, which will pollute the soil when used directly, accelerate the evaporation of soil moisture, burn the root system of crops, and affect the germination of seeds. The correct way to use it is to fully compost and rot the farm manure and cake manure first, and then use it after high temperature sterilization or chemical treatment.

2) Chlorine-containing fertilizers should not be used in saline-alkali land and chlorine-resistant crops.

Chlorine crops include potatoes, watermelons, etc.

3) Nitrogen fertilizer should not be applied shallowly or before watering.

After nitrogen fertilizer is applied to the soil, it is generally converted into ammonium nitrogen, which is easy to volatilize with water loss or light and heat, and loses its fertilizer effect.

4) Ammonium nitrogen fertilizer should not be mixed with alkaline fertilizer such as plant ash.

5) Nitrogen fertilizer should not be applied to leguminous crops.

There are nitrogen-fixing rhizobia in the roots of the leguminous family, and excessive application of nitrogen fertilizer not only causes waste, but also affects the yield due to greedy green and late ripening.

6) Phosphate fertilizer should not be used in a dispersed manner.

The phosphorus element in phosphate fertilizer is easy to be absorbed and fixed by the soil and loses the fertilizer effect, so the phosphate fertilizer should be mixed with the accumulated fertilizer for a period of time, and then applied in furrows or holes near the root system.

7) Fertilizers with high phosphorus content should not be used for vegetables.

Vegetables have a relatively small requirement for phosphorus.

8) Potassium fertilizer should not be used in the late growth stage.

When there are symptoms of potassium deficiency, the growth is almost late, and then topdressing can not play much role, so potassium fertilizer should be applied to the seedling stage in advance, or used as base fertilizer.

9) Rare earth fertilizers should not be applied directly to the soil.

Rare earth fertilizers are used in small amounts, and the correct way to use them is to mix them with seeds or use them for foliar sprays.

10) It is not advisable to apply fertilizer indiscriminately regardless of variety and growth period.

Different types of vegetables with different growth periods have different needs for the variety and quantity of fertilizer, and should be treated differently.

Nutritional characteristics of vegetable crops:

Vegetables are highly intensively cultivated crops. There are many types and varieties of vegetables, the growth and development characteristics and product organs are different, the vegetables need a large amount of fertilizer, the growth period is short, and the nutrients taken away from the soil are more. 1. The root system is shallow, only about 30 cm; 2. The root length density is low, which is one-third of that of gramineous crops; 3. Poor root growth environment

Soil-borne diseases, out-of-season low temperatures, and salt damage are common.

Ensure the continuity of root nutrients at relatively high nutrient concentration levels (5-10 times that of field crops) and relatively high soil moisture (generally 70% of plant available water)**!

1. Characteristics of the nutrient demand of nightshade fruits.

Such vegetables (tomatoes, eggplants, peppers, and bell peppers).

The requirements for soil oxygen content are high, and poor aeration will affect the root pair.

Nutrient absorption. The amount of fertilizer required at the seedling stage is small, but the nutrition is comprehensive, especially.

It is sensitive to nitrogen and phosphorus, and if it is deficient, it will affect flower bud differentiation.

and fruit quality. After planting, the amount of fertilizer required increases until the first ear fruit sits, and after that, the amount of nutrients uptake increases dramatically. Their growth characteristics are:

While flowering, fruiting, large growth, high fertilizer demand, strong fertility tolerance.

Nutrient imbalance can easily cause physiological diseases, such as calcium deficiency in tomatoes.

Cord rot. In production, it is necessary to pay attention to the contradiction between the growth of trees and the fruit.

In fertilization, more organic fertilizer should be applied to improve the soil, and attention should be paid to the application of phosphorus and potassium fertilizers to ensure the nutrients of nitrogen, phosphorus and potassium.

Vegetable fertilization depends on the soil fertility, the varieties of vegetables planted, and the growth of each growth period.

Different vegetable fertilization methods are not exactly the same, what vegetables are you growing?

Vegetable planting dry goods to share:

1. After the base fertilizer is applied, the microbial agent fertilizer is supplemented to improve the decomposition and transformation efficiency of the base fertilizer, promote the soil aggregate structure, reduce harmful bacteria, and create a healthy and ecological environment for the root system.

2. After planting, use liquid water-soluble fertilizer that can supplement organic matter, and choose different amounts of water-soluble fertilizer according to different times, which can make the root system better and better, and can also supplement various nutrients required by plants because of growth needs, reducing soil barrenness and premature plant aging.

3. Foliar supplementation of organic acid boron-calcium foliar fertilizer can solve various problems caused by boron and calcium deficiency, and the effect of calcium and boron supplementation is better.

The above three points are simple and easy to operate, have you learned them? Hope it helps!
