When it comes to growing vegetables, what is the best time to fertilize?

When planting vegetables, fertilization is the best time to apply fertilizer in spring, and if you apply fertilizer during this period, the climate and temperature conditions are very moderate, and in autumn it will generally grow well.

The fertilization time for planting vegetables depends on the specific crops you plant, for example, Chinese cabbage is planted in early March, you need to use a base fertilizer before planting, and then you need to fertilize once a week; In mid-April, with the use of Bika water-soluble fertilizer, it can be collected and marketed at the end of May.

When planting vegetables, it is the best period for fertilization before the vegetables are about to grow vigorously, and fertilization during this period can effectively promote the rapid growth and development of vegetables and obtain high quality and high yield.

Fertilizer can be divided into base fertilizer, seed fertilizer and top dressing according to different application periods, application purposes and methods.

Basal fertilizer is a fertilizer applied to the soil in combination with soil tillage before sowing or transplanting. Organic fertilizers are usually the main ones. Its role is to fertilize the soil and nutrients throughout the plant's growth period.

In order to give full play to the role of basal fertilizer, different application methods such as sprinkling, strip application, and layered fertilization are often used according to soil characteristics, tillage methods and fertilizer properties.

No matter what vegetables are grown, base fertilizer is indispensable. That is, when cultivating the land, it is necessary to bury the bottom fertilizer in the soil. Only in this way can it be beneficial to the growth of vegetables. In the middle and late stages of vegetable growth, it should be topdressed in time according to the growth situation!

1. Classified fertilization.

In summer, common vegetables are mainly beans that have root nodules themselves, which can fix nitrogen fertilizers, but need to be supplemented with other fertilizers. Legumes need to be supplemented with calcium, and phosphate and rhizomes also need potassium. Plant vegetables vegetables need enough nitrogen fertilizer to ensure that the leaves are soft and green, some potassium fertilizer should be applied, and some phosphate should be employed.

Manure. Root vegetables, mainly grow roots, so there is a lot of potassium fertilizer, and the use of phosphate fertilizer, in the summer rhizomes are growing, it is necessary to apply less. The root of the protein is stronger than that of other vegetables, and the fertilization summer is the main fruiting period, with the application of small phosphate fertilizers, and also the addition of trace element fertilizers.

2. Temperature influence.

When the temperature is low in early summer, the soil temperature is not so high and it is the best time for fertilization. The soil temperature is not that high. Summer temperatures increase fertilization, it is better to use water to dissolve, preferably after the afternoon, do not use fertilizers, and use small amounts.

Do not fertilize for less than three days, it is better not to fertilize at all.

3. Weather influence.

Sunny day.

Do not fertilize on cloudy days.

Fertilization, or after the afternoon, it is very good for fertilization, but it tends to be heavy in the summer, so after the rain, after the rain, the soil will gradually dry after fertilization. If the rain is not fertilized in the rain, the fertilizer will be pulled apart and the roots will not be absorbed. or roots with too much water, fertilizer is useless.

4.Use fertilizers.

Generally, use agricultural fertilizer, livestock fertilizer, straw pile, vegetable leaves, small fertilizer, fertilizer and a small amount of fertilizer, do not use domestic poultry fertilizer, high heat, damage to roots. It is more suitable for fertilizers with low thermal properties that use completely decomposed treatments. The concentration of fertilization does not exceed the concentration of the soil solution, otherwise the fertilizer will not be absorbed.

5. Fertilization period.

Tomatoes are mainly used for fertilization to promote fruiting and ensure the nutrients of the plants during the summer fruiting period.

Beans are mainly found in pods.

period, it is necessary to ensure nutrition and avoid yellow plants. During the flourishing foliage, the leaves are dished to ensure that the fertilizer keeps up. Ice is not too much, and it can break easily.

Vegetable summer fertilization is mainly based on the type of vegetable and environmental impact, and the amount of fertilizer will be determined, and the fat will be applied. Pay attention to the fertilization period and apply fertilizer appropriately.

The fertilization time for planting vegetables depends on the specific crops you plant, for example, Chinese cabbage is planted in early March, you need to use a base fertilizer before planting, and then you need to fertilize once a week; In mid-April, with the use of liquid fertilizer, it can be collected and marketed at the end of May.

The amount and type of fertilizer should be determined according to the growth period of vegetables and soil nutrition. Generally, when the nutrition is insufficient at the seedling stage, a small amount of foliar fertilization can be carried out, and the plantation should be applied with plantar fertilizer, and different fertilizers such as nitrogen, phosphorus, potassium, and trace elements should be applied according to the lack of fertilizer in vegetables during the rapid growth period.

Plant vegetative reproduction and growth at the same stage, the leaves are probably soothing, at this time the vegetables have grown to about 60 percent, the male spike also began to differentiate, this is an important period for the formation of panicle grains, at this time the fertilization is mainly nitrogen fertilizer nitrogen fertilizer 5 10, you can also increase potassium fertilizer, sufficient water and fertilizer can feed vegetables nutrients can be increased, if the water and fertilizer is insufficient, it may lead to only grow plants do not grow vegetables, resulting in reduced yield.

Planting vegetables should be diligent in taking care of them, in order to eat fresh vegetables as soon as possible, but when is the best time to fertilize vegetables, we generally use organic fertilizer for vegetables, and from time to time to top dressing vegetables, only diligent people can grow good vegetables. <>

Plant melons and get melons, plant beans and get beans.

The farmers who grow vegetables are very hard, so we can't waste food and have to take action on a disc for three meals a day, planting vegetables also has a certain technical content, not everyone can grow vegetables well, and eat fresh and pollution-free vegetables.

Understand management and take care of it.

First of all, we need to know what kind of fertilizer is suitable for the kind of vegetables planted, generally we will apply phosphorus and potassium fertilizer to the vegetables, and urea can be added whenever the vegetables grow.

Water-soluble fertilizer, and increase the number of fertilizer spraying according to the growth of vegetables.

It is also necessary to pay attention to the insect prevention of vegetables, many vegetables are very provoking insects, we must do a good job of protection, can not work hard to plant good vegetables to let the insects eat, so as not to get a bumper harvest, and the vegetables are very fond of water in the place can not let the vegetables dry water, which will make the vegetables not big enough. In short, no matter what vegetables are planted, they need to be carefully cared for, if you really don't know how to cultivate vegetables can collect relevant vegetable planting information, you can also buy a book about vegetable planting, learn well, and some vegetable fields can not only plant one vegetable every year, we need to plant different vegetables every year, because the soil needs to be replaced every year to plant different vegetables to make the land more fertile, and it is also difficult to weed vegetables, we are spraying herbicides.

When not, be careful not to spray pesticides on the foliage of vegetables, so that we will not eat vegetables with pesticide residues, the diligent older generation will always plant a vegetable field at the door of the house, so that not only can you eat fresh vegetables but also very convenient, and finally I wish you all to plant melons and melons and beans and beans.

It is just when planting, and the fertility of the soil must be guaranteed, so you must apply more base fertilizer, and then you should also choose a mixture of organic fertilizer, phosphorus fertilizer, and nitrogen fertilizer.

Two weeks after planting vegetables is the best time to fertilize the seeds, when the seeds can fully absorb the nutrients.

Base fertilizer is needed before planting, and fertilizer is also needed according to the growth of the plant during the growth period of planting, and top dressing is carried out.

Vegetables need to grow vigorously in order to have a good harvest, so if you want the plant to grow full and strong, you need to give top dressing in time, when it comes to top dressing, there are many types, for example, we can use fermented animal manure as fertilizer, which can make the plant grow quickly and grow very well.

Cabbage grows fast, grows a lot, needs a lot of fertilizer to supplement nutrition, and has a long-lasting fertilizer to lay the foundation, so it is necessary to reapply base fertilizer, mainly organic fertilizer, because organic fertilizer has the effect of promoting root development and improving resistance to Chinese cabbage. Of course, different vegetables should use different fertilizers, organic fertilizer is completely produced in the countryside of natural fertilizer, such as, pigs, cattle, sheep, chickens, ducks, geese and other manure, straw, straw, rapeseed oil residue, etc., chemical fertilizers include phosphate fertilizer, nitrogen fertilizer, compound fertilizer, urea, etc. Their respective uses are slightly different, and organic fertilizers can participate in the whole process of crop growth, which is conducive to good yields.

Vegetables are generally short-term nutritious crops, which can be replanted with multiple crops: many kinds of vegetables such as Chinese cabbage, radish, winter melon, cucumber, etc., often have a yield of more than 5,000 kilograms per mu, so they require a large amount of fertilizer. Some fast-growing vegetables such as cabbage, four seasons radish, coriander, etc., have a short growth period, and the nutrients absorbed are more suitable than urea vegetables with a longer growth period, with fast absorption and concentrated nutrients.

Only a few vegetables that like potassium but not nitrogen have no obvious effect. The application of urea is best carried out after rain, as the weather will burn the vegetables. It is not recommended to apply before heavy rain.

Vegetables require more mineral elements, and if only urea is applied, it cannot ensure high yield of vegetables. Second, the growth period of vegetables is short, generally one or two months can be harvested, and urea is a chemical nitrogen fertilizer after all, which will pollute the environment, and will make vegetables have chemical residues, threatening our health. Leafy vegetables:

The main food organs are stems and leaves, and the demand for nitrogen fertilizer is greater, and the plant grows vigorously and the higher the yield. For example, fast-growing leafy vegetables (bok choy, fast cabbage, rape), as well as cabbage, Chinese cabbage, celery, coriander, etc., all need more nitrogen fertilizer, or just apply pure nitrogen fertilizer.

Fertilization can be done after germination, and phosphorus, nitrogen and potassium fertilizers should also be chosen, and they should also be watered in a timely manner, and they should also be planted in sunny places.

It is most appropriate to fertilize the vegetable when it is first planted, and then fertilize it when it grows seedlings, so that the yield of planting is particularly high.

When the green leafy vegetables have not yet grown, it is the most suitable for fertilization, and after fertilization, it absorbs nutrients and can grow well.

It is good to fertilize when planting vegetables and sitting behind the fruits.

The top dressing of vegetables is really important, and the vegetables grow well or not, and the results are directly related to fertilization. When to top dressing vegetables is also important, master the top dressing time of vegetables, in order to ensure that vegetables have enough nutrients in the rapid growth period, so as to grow well, bear more fruits, and have high yields.

There are dozens of kinds of vegetables we often plant, and the fertilization of different vegetables is very different, how can we better grasp the fertilization methods of these common vegetables. In fact, the way we plant vegetables is mainly determined by the way it bears fruit, and the number of fertilization times for continuous fruiting vegetables and one-time harvested vegetables is definitely different.

Knowledge of growing vegetables

Most of the vegetables are annual: spinach and other leafy vegetables, tomatoes, peppers, melons, beans, you have to understand the climate of the place where you live. Leafy vegetables are less afraid of cold and can be grown when the land is warm.

However, tomatoes, peppers, melons, beans, and eggplants are all very resistant to frost, so you must wait until there is no danger of frost damage before planting.

In cold areas, the summer is very short, and if you wait until the frost-free period to plant again, there is a possibility that the summer will not be harvested, so you need to buy seedlings at the gardening store and plant them, so that you can grab two months. If you must plant your own seeds, you must first sow them indoors in mid-March, so that they are just right for the end of May and early June.

We should spread fertilizer on the ground, and we should also water it frequently, treat weeds, and prune branches and leaves, so that it is the most scientific and the yield is very high.

1. Ground sprinkling.

After watering vegetables or when it rains, sprinkle chemical fertilizer on the furrow surface or between the rows of plants. This method is relatively simple, time-saving and labor-saving, but the utilization rate of fertilizer is low, and volatilization will lose part of the fertilizer. In particular, ammonium bicarbonate is extremely volatile, and scattering is not recommended; Urea, ammonium sulfate and potassium sulfate can be sprinkled in the field when the operation is inconvenient and the vegetables are in urgent need of fertilizer.

Do not sprinkle on the leaves when spreading to avoid burning the leaves.

2. Apply with water.

Before watering vegetables, the fertilizer is sprinkled in the ditch so that the fertilizer dissolves into the soil with the watering. This fertilization method, on the one hand, there will be some volatilization loss, on the other hand, there will be part of the water seepage to the deep soil layer, because the vegetable root system can not reach and can not be absorbed and utilized. Its advantages are that the method is simple and the amount of labor is small.

In the case of severe lack of fertilizer in large areas of vegetables and inconvenient burial, it can be used as the preferred topdressing method. It is best to dissolve the fertilizer before flushing and then rinse it with water.

Leafy vegetables need more water and fertilizer in the whole growth period, in addition to the application of foot fertilizer, should be carried out at the seedling stage, in the middle and late stages of 1 2% urea spraying can accelerate the leaf extraction and rapid growth, and can save costs and improve nitrogen fertilizer use efficiency, rhizome vegetables need more phosphorus and potassium fertilizer than nitrogen fertilizer during their whole growth period, especially in the middle and late stages of potassium fertilizer need more sensitive and more.

First, the base fertilizer.

The role of basal fertilizer is twofold, on the one hand, it can improve the soil and fertilize the soil; On the other hand, nutrients can be continuously added throughout the growth period of vegetables. Therefore, the amount of basal fertilizer is larger, accounting for more than half of the total amount of fertilizer. The base fertilizer is mainly organic fertilizer, and chemical fertilizer is appropriately applied.

Combined with deep ploughing and raking. It is better to apply the base fertilizer deeply.

Second, plant fertilizer. The role of seed fertilizer is to supplement the deficiency of base fertilizer, on the one hand, to supply nutrients in the early growth stage of vegetable crops; On the other hand, it promotes seed germination and ensures the optimal nutrient quality of nutrients in the critical period of nutrition. Seed fertilizer is generally used with well-rotted organic fertilizer or fast-acting fertilizer, and the application amount should be small. All kinds of fast-acting chemical fertilizers, completely decomposed organic fertilizers (such as cake fertilizer, poultry manure, etc.), biological fertilizers, trace element fertilizers, etc. can be applied as seed fertilizers.

The fertilizer efficiency of seed fertilizer is determined by factors such as soil, fertilization technology and cultivation management measures. Because the fertilizer and the seeds are in close proximity. Therefore, the quality and dosage of fertilizer are particularly strict, otherwise it is easy to cause seed burning and seedling burning, resulting in lack of seedlings and broken ridges.
