Does the spinach that has just emerged need to be fertilized? What fertilizer is better?

Does the spinach that has just emerged need to be fertilized? What fertilizer is better? Spinach is a vegetable that many friends often grow in the autumn and winter.

It is very resistant to cold and can be overgrown without too complicated management. Farmer Lao Liu also planted some spinach this year, and chose two varieties, one is large-leaf spinach, which was planted relatively early and has just sprouted now, and the other is round-leaf spinach, which is ready for winter planting at low temperatures. The fertilization of spinach also depends on the use of basal fertilizer and the growth of the plant.

Spinach mainly eats stems and leaves, and needs to be fertilized with more nitrogen.

<> spinach grows 2 3 true leaves, roots and leaves are relatively small, has not fully entered the vigorous growth period, this period should be less fertilization, I think it is also recommended to be sufficient, and the seedling growth is better, and the fertilizer effect period is long, there is no need to fertilize, only need to pour a pot of water when the soil is dry, and the manure is continuously released in the soil to provide seedling growth. After a few days, the weather becomes cooler, spinach grows faster, then the need for fertilizer water will increase, you can carry out top dressing during this period, you can use some fast-acting nitrogen fertilizer, commonly used urea, to promote leaf growth. You can also spray some foliar fertilizer, such as sesame cake fertilizer, amino acid liquid, etc.

This is the top use of autumn spinach planting, but the spinach planted in winter, like the round-leaf spinach planted by Lao Liu, cultivates strong seedlings before winter, and after growing three leaves, it is combined with watering and fertilizer to promote the growth of seedlings.

Therefore, the weather environment is different, and the fertilization also changes. There are also some farmers in order to catch up with the sowing period, there is no time to fertilize, before planting crops to apply more fertilizer, spinach can also germinate, after the emergence of seedlings, to apply a seedling fertilizer on it, mainly with chicken manure or fast-acting nitrogen fertilizer. Whether it is chicken manure or manure water, it is best to reuse it after it is fully decomposed.

Although semi-rotted manure can raise the ground temperature in winter, it is also important to avoid burning the roots, which is not good for spinach growth. The high yield of spinach depends on water and fertilizer. Compared to other leafy greens, spinach has a longer growth cycle and requires sufficient nutrients and water throughout the growth process so that small gardens can grow spinach with high yields and tender taste.

Whether the spinach that has just emerged needs to be fertilized, it depends on whether its base fertilizer is sufficient, if it is to be supplemented, it is best to spray some liquid nitrogen fertilizer, which is conducive to the transformation and absorption of spinach seedlings. If the base fertilizer is relatively sufficient, then there is no need for special top dressing, only need to add an appropriate amount of water. 

Spinach is a fast-growing vegetable, fast growth, high yield, so the corresponding need for fertilizer is also larger, spinach to potassium fertilizer demand is the largest, nitrogen fertilizer second, the least demand for phosphorus, so potassium fertilizer is better.

Yes, it is best to choose organic fertilizer, which can promote the growth of spinach, prevent pests and diseases, and make spinach more robust.

Yes. At this time, you need to apply some nitrogen fertilizer, phosphate fertilizer, and potassium fertilizer, of which potassium fertilizer needs a little more, and you can apply a little more appropriately.

Spring spinach is sown early, and it can be sown by thawing about 10 cm on the soil surface. However, spring spinach must be fertilized before the soil is frozen, and then turned deep into furrows for early spring sowing. The spinach I planted has already emerged, because I applied enough fertilizer when I planted the spinach, so I don't need to apply fertilizer after the seedlings appear.

After the seedlings are evenly planted, a small amount of urea is applied once and watered with water. If the bottom fertilizer is less or no bottom fertilizer is applied, urea can be applied once after the emergence of seedlings, and it should also be watered with water. Spinach is cultivated in spring and autumn, and is generally sown in autumn.

The best time to do this is from early August to early September. It can be harvested in batches 30 to 40 days after sowing.

<> spinach takes a long time from sowing to harvesting, so we must apply enough basal fertilizer, i.e. base fertilizer. However, it is also important not to fertilize too much, which will also cause spinach to grow vigorously. Generally, we use well-rotted farmhouse fertilizer and a certain amount of phosphorus and potassium fertilizer mixed fertilization.

It is also necessary to pay attention to the topdressing of spinach seedlings just emerged, and finally chose to be at five or six o'clock in the evening, when the sun went down, the temperature also came down, and the manure was poured into the spinach seedling soil so that it would not be steamed by the sun, and when the spinach seedlings grew two or three leaves, they could be watered with manure and top dressing. Spinach likes nitrogen fertilizer, and when spinach grows four or five leaves, urea can be applied with water.

Before the sowing of spinach, it is necessary to pay attention to the watering work, and when to stop watering management after the young seedlings grow. In the late growth stage, fertilizer will increase, so everyone needs to add a certain amount of fertilizer. Generally speaking, spinach can be grown for three seasons, 1

Turn the land deeply, according to the size of the area, apply a certain amount of rotted farmhouse fertilizer, and apply an appropriate amount of compound fertilizer as base fertilizer. Only when the basic work is done well, spinach absorbs enough nutrients in a nutrient-rich environment, and the growth period of spinach has a process, and the growth period is about one to one and a half months.

At this time it is possible to fertilize. Because the seedlings had just emerged, fertilizing would make the spinach grow faster. is nutritious.

Can be fertilized. Because spinach seedlings at this time need a lot of nutrients. Therefore, it is better to apply some fertilizer to spinach seedlings.

No, because if you fertilize during this time period, it will definitely cause the spinach seedlings to burn to death, so you can water them first.

OK. Because some nutrients are needed at this time, it is very useful to make them grow very quickly.

Yes, this is because fertilization can increase yields and prevent spinach from developing pests during the growth process.

Of course, you can, because the spinach seedlings at this time are very nutritious, and timely supplementation of nutrition will make the spinach seedlings grow stronger.

OK. Because the spinach that has just emerged is the time when it needs nutrients, fertilizing at this time will make the spinach grow faster and will also increase the yield of spinach.

It is best not to fertilize the spinach that has just emerged, at this time it is the stage when the spinach and sweet potato dust long wheel Zen is vigorous, and the hand stove of fertilization can use some insect repellent on it, and other fertilizers are not needed now.

Fertilization can help spinach grow more auspiciously, improve the nutritional value of spinach, make spinach better protected, make the growth of spinach better, and increase the growth rate of spinach. You can choose potassium fertilizer, you can choose nitrogen fertilizer, you can choose compound fertilizer, you can choose farm fertilizer, these fertilizers can help spinach grow better.

In this case, it is generally not fertilized, which is easy to lead to the death of seedlings, and some farmhouse fertilizer can be used, but you must pay attention to the amount.

The time from sowing to maturity of spinach is relatively long, so be sure to apply foot fertilizer when planting winter spinach. Nitrogen fertilizer is the key to ensuring the rapid growth of spinach.

Fertilize according to the growth of plants, you can use some farmhouse fertilizer, be sure to pay attention to the time, how much, and pay attention to the rainy weather.

When we grow vegetables at home, the first thing is to have enough light, and then we need to choose the right vegetables, and the space between the plants should be ventilated.

The main reason is that I want to eat pure natural Xinxiang spinach, so I will not fertilize, although the spinach looks not very good-looking and does not grow big, but it tastes unique, it is also very delicious, I don't want people to plant spinach in the greenhouse, spinach high yield has a lot to do with the selection of varieties, seed treatment will be carried out before sowing, spinach will be soaked for 12 24 hours, and then placed in a cool place for spring sprouts, which is conducive to seed germination rate. When germinating, observe the seeds, keep the seeds moist, and wait for the seeds to germinate before sowing.

The amount of water and fertilizer absorbed is relatively large, at this time it is necessary to carry out top dressing, 15-20 kg of ammonium sulfate can be used per mu as top dressing, it should be noted that the growth cycle of spinach planted in early spring is short, so it is necessary to supplement nitrogen fertilizer to promote the rapid growth of spinach leaves and prolong the sprouting. As a result, the tips and margins of spinach are yellow-brown, the roots are brown, and the growth stops, and even dies. Spinach is a fast-growing green leafy vegetable, which needs more nitrogen fertilizer during the growth process, and if there is too much nitrogen fertilizer, it will lead to poor leaf and cold resistance, so it is appropriate to apply phosphorus fertilizer.

When the spinach sprouts begin to grow, water them once, and the amount of water should not be large. Spinach will soon reach a rapid growth period after returning to green, and should be given enough fertilizer water, watering water should be larger, and fertilizing once with watering. Generally, in the middle and late stages of growth, the amount of fertilizer and water absorbed by spinach begins to increase, and at this time, about 15 to 20 kg of ammonium sulfate can be applied to each acre.

Because the growth cycle of spinach in spring is relatively short, sufficient nitrogen fertilizer can make spinach leaves grow vigorously.

It is mainly high furrow or flat furrow. For wintering spinach, choose soil with sufficient fertility, deep soil layer and good fertilizer and water retention. Compared with other seasons, the amount of basal fertilizer should be appropriately increased, and the soil should be deeply turned so that the soil and fertilizer can be fully mixed to promote the emergence of seedlings.

There is no need for top dressing during the overwintering stop growth period. In early spring, the growth period is 30-40 days, when the spinach leaves turn green and the heart leaves begin to grow, you can water 1 time. After spinach enters the vigorous growth period, it should be topdressed in time, combined with watering, 10-15 kg of ammonium sulfate per 667 square meters.

1. Apply sufficient base fertilizer. Big-leaf spinach has a short growth period, is a fast-growing vegetable, the whole growth period has high requirements for fertilizer, insufficient fertilizer will cause the leaves to look bad and easy to flower, and the fertilizer effect of organic fertilizer is long, can meet the needs, so the application of sufficient base fertilizer is the key. 2. Apply top dressing in time.

Spring large-leaf spinach in the early stage of growth, generally do not need to apply fertilizer water, in order to absorb nutrients in the soil, but in the middle and late stages of growth, the amount of fertilizer absorbed increases, 15-20 kg of ammonium sulfate can be applied per mu, in addition, due to the short growth period of large-leaf spinach in spring, sufficient nitrogen fertilizer can make the leaves grow vigorously and delay the sprouting period. 3. After the large-leaf spinach seedlings are unearthed in autumn, when 4-5 true leaves grow, 2-3 times of fast-acting nitrogen fertilizer should be applied in stages, and 20-25 kg of ammonium sulfate or 10-12 kg of urea should be applied per mu to promote the thickening of the leaves, increase the yield and improve the quality.

Spinach leaves after watering a manure, top dressing to do the first light and then thick, the early stage should be more farm fertilizer, in the vigorous growth period to top dressing 2 to 3 times, can choose urea per mu about 10 kg.

About two weeks before the spinach harvest, a fast-acting nitrogen fertilizer should be applied, and gibberellin can also be appropriately treated to improve yield and quality.

When fertilizing spinach, it is necessary to pay attention to the application of sufficient basic fertilizer before sowing, keep the soil fertile, nitrogen fertilizer, phosphate fertilizer and potassium fertilizer should be properly matched, and strengthen fertilizer and water management after overwintering and returning to green, and strictly control the top dressing time.

Spinach base fertilizer must choose organic fertilizer, because organic fertilizer is mild, and the dosage is two tons per mu.

First of all, turn over the whole land, then add some basic fertilizer to it, and then take good care of it.

We must strengthen the management of ventilation, and do not apply too much fertilizer when fertilizing, we must keep it even, and we must keep the soil loose and breathable.

Spring spinach sowing early, can be fertilized in the previous year, every 667 square meters of rotting organic fertilizer 4000-5000 kg, deep 20-25 cm, rake flat furrow, when the early spring soil thaw 7-10 cm deep can be sown. It is advisable to choose neutral clay soil, and a mixture of compost and chemical fertilizer can be used as base fertilizer.

Finally, it is put into the environment of 15 degrees to 20 degrees for germination, and generally waits for about three or four days, and the seeds can be sown when they are white. The sowing method is mostly sprinkled, and then sowing is sown with sufficient water, and the dense thickness of sowing should not be too dense. Usually there will be late emergence and low emergence rate, so it is also the key to spinach cultivation when it is necessary to treat the seeds when cultivating spinach in the hot weather of summer.

Spinach is rich in vitamin C, vitamin K, carotene, calcium, iron and other nutrients, which have great benefits for the human body. Spinach also has the ability to nourish blood, stop bleeding, treat blood in the stool, and scurvy can be effective in summer, spinach is very prone to cataplexy and blight at the seedling stage, resulting in the phenomenon of dead seedlings and broken ridges, affecting the yield. Therefore, planting summer spinach should be disinfected in the soil, generally 2 to 3 days before spinach sowing, with 50 seed dressing double powder, or with 50 carbendazim.

When planting spinach in summer, you must avoid using varieties that are early and early to smoke, and choose varieties that are resistant to high temperatures and smoke late, such as round-leaf spinach. The variety of planting determines the level of yield, and it is very important to choose the right variety for planting. Watering:

After the emergence of seedlings, it is best to use sprinkler irrigation method to water, in order to reduce the air temperature and ground temperature, avoid flood irrigation and water formation, when using sprinkler irrigation, need small water to water frequently, water flow should be slow, in the evening is appropriate.

After the emergence of seedlings, it is best to use sprinkler irrigation to water to reduce the temperature and temperature, remember to flood irrigation and stagnant water. When using sprinkler irrigation, you need to water frequently, the water flow should be slow, when watering the winter wheat back to green water and top dressing, spinach will grow very quickly after absorbing sufficient nutrients and water, and every year around mid-April, you can eat the spinach planted in the previous winter in the evening. Buy high-quality spinach seeds 2 choose good soil 3 sprinkle seeds and buckle the film, which can shrink the water, and the small greens grown at home will also have insects without pesticides, but spinach does not grow insects and does not need to be watered, which is more drought-tolerant.

If you want to have a high yield, spinach will grow more vigorously and shrink the nutrients. 4. Water more. 5. Frequent ventilation.
