How to fertilize pumpkin to be productive and productive? How to fertilize pumpkin at different grow

Pumpkin is a vine crop with a well-developed root system, deep burial, strong water absorption, strong fertility, drought resistance, and strong fruitlessness. Therefore, the requirements for the soil when planting are not strict, but it is best to plant in sandy clay soils with deep soil layers, good drainage, and fast heating. Pumpkin seedlings require less fertility, but when the fruit swells, the demand for fertility increases dramatically, especially for nitrogen fertilizers, followed by increased uptake of potassium and phosphorus for watering.

What are the soil requirements for pumpkins?

In fact, pumpkins are not strict on the soil, for example, pumpkin seedlings can be seen on rural roads and in front of and behind rural houses. But if you are growing pumpkins as an industry, if you want to get a high yield, stable yield, and high quality, you should choose sandy clay or clay rich in organic matter, and it is better not to grow it in clay and low-lying areas. The best plot to grow pumpkins is to start growing them at the border.

The depth of the ditch and the height of the boundary are conducive to sprinkling and drainage. In general, the width of the border is about 2 meters. <

How do you prune pumpkins?

There are many ways to prune pumpkins. For example, the single-vine pruning method, which leaves only the main vine and melon, is only suitable for early-maturing varieties, which removes all side branches and leaves and is only used to produce melons. Especially pumpkins that are planted closely.

For example, this method is used to frame pumpkins. Medium and late varieties usually receive a lot of pruning, and when the main vine reaches 5-7 knots, it chooses a heart shape, leaving 2-3 side branches to set the melon. This method is often used for pumpkins grown in greenhouses.

Otherwise, the seedlings will stretch around, affecting photosynthesis and field management. <>

What should be paid attention to in the management of pumpkin fertilizer?

Pumpkins have a well-developed root system and a strong ability to absorb fertilizers. It is one of the vegetables that needs fertilizer the most. Fertilization should follow the principle of main fertilizer weight and less fertilizer.

The basal fertilizer is mainly high-quality organic fertilizer, which is rich in nutrients such as nitrogen, phosphorus and potassium, which is necessary for the growth of the whole growth period. After transplanting the slow seedlings, fertilizer can be applied in time according to the growth of the plants. In the early days, organic fertilizer was the main fertilizer.

At the fruiting stage, the fertilizer is corrected with water and attention is paid to the application of phosphorus, potassium and trace element fertilizers. <>

In fact, in order to achieve high yield in the later stage of pumpkin, pumpkin needs scientific and reasonable management throughout the growth period. However, because the pumpkin is very resistant to disease and the plant itself has a strong vitality, it has laid a certain foundation for the variable yield of pumpkin. According to the question asked by the subject, I will talk more about some experience in planting pumpkins in rural areas from the aspect of fertilization.

1. Bottom fertilizer before sowing.

When planting pumpkins in rural areas, the bottom fertilizer is generally well-rotted pen manure, such as pigsty manure, chicken pen manure and so on. One of the characteristics of these manure is that there is more organic matter, which has a very good effect on improving soil porosity. Soil that is applied regularly will become very fertile.

Choose some open space with relatively high terrain, and then hoe to loosen the soil for about 30. It is best to loosen the soil, the frozen soil is the best, and then the well-rotted manure is applied to the bottom 30 of the soil. In addition to the application of manure, some fermented rapeseed cake fertilizer can also be applied.

Second, raise seedling fertilizer.

When the pumpkin vine grows to about 50, you can carry out a topdressing of seedling fertilizer. At this time, the pumpkin root system is not large enough, just dig a small pit 30 meters away from the root system, sprinkle some urea or rotten cake fertilizer, and then cover the soil and water.

3. Puffed fruit fertilizer.

After the application of seedling fertilizer, until the flowering and fruiting period, there is basically no need for top dressing. However, it still depends on whether the pumpkin seedlings grow well or not, if the pumpkin seedlings grow more generally, you can carry out another topdressing in the early stage of vine extension. At this time, top dressing can be mainly nitrogen, phosphorus and potassium compound fertilizer.

Generally, after the pumpkin sits on the melon, we can apply the puffed melon fertilizer. When the first pumpkin sits on the melon, it is the time when the seedlings and young melons grow synchronously, at this time, the top fertilization is mainly based on nitrogen, phosphorus and potassium ternary balance fertilizer, and some calcium and magnesium fertilizer are appropriately supplemented on the foliar surface. Or apply some plant ash and rapeseed cake fertilizer.

Here it is necessary to pay attention to the appropriate supplement of calcium and magnesium fertilizer, and in the middle and late stages of pumpkin fruiting, there is a large demand for calcium fertilizer.

Base fertilizer The base fertilizer is mainly organic fertilizer, with nitrogen, phosphorus and potassium fertilizer, planting pumpkin, the bottom fertilizer, the bottom fertilizer is mainly organic fertilizer, and then some nitrogen, phosphorus and potassium compound fertilizer.

You can add more fertilizer so that it can grow very well. So, in the early stage, you can pay for water, dry fertilizer in the middle stage, and dry fertilizer in the late stage.

First of all, before planting, organic fertilizer should be used as base fertilizer, and after the emergence of seedlings, it is enough to chase compound fertilizer once a month.

Pure natural green pumpkin seedlings are planted with farm fertilizer to be tender and crisp, and have a unique farm flavor. It is best not to use any chemical fertilizer, generally apply livestock feces and urine mixed with grass and wood ash farmhouse fertilizer, the seedlings are strong and grow quickly, and the taste is returned after eating. If you do not take defensive measures in time for a long time, it will cause a large number of pests and diseases in the field, resulting in a large number of pumpkin growth being affected, so it is necessary to use and spray moisture to be able to play a defensive measure.

Generally, in such a situation, it is better to spray some agents such as chlorothalonil and carbendazim.

First of all, if you dig a hole in it, the depth is about five centimeters. Then put the pumpkin seeds in the pit, and water some water, and after the water completely penetrates into the soil, apply a little compound fertilizer not far from the seeds, so as to ensure that the pumpkin has sufficient fertilizer during the growth process to speed up the growth of the melon seedlings. It is necessary to apply nitrogen fertilizer in time in combination with watering, several times a month, and fill the soil at the base, so that the stems and vines can be in contact with the soil as much as possible, so that the vines can produce adventitious roots at the stem nodes, increase the absorption of water and fertilizer by the vines, let the stems and leaves grow luxuriantly, and increase the growth and yield of pumpkin.

It can't be a pumpkin seedling, how can the pumpkin seedling be small? Pumpkin is not only edible for vines, but also edible for pumpkin flowers. Whether it tastes good or not is different according to personal taste, I don't think it tastes good, but it can be eaten.

If you want the pumpkin vine to grow well and strong, it is easy to apply more urea pumpkin leaves to grow luxuriantly, pour it directly on the roots of the pumpkin seedlings, and water it with alkaline water every other week. When pumpkin seedlings grow relatively long and have many forks, the alkaline water after washing clothes is poured directly on the roots once a week. That's how my family fertilizes pumpkin seedlings, and it's growing very well.

There is a variety of edible part is the side bud out of the tender head, there are also called brain head, delicious, nutritious, very popular, the management is more extensive and simple, the management of seedlings after planting to keep up, do not make the soil around the seedlings compacted fertilization lighter, and so on 5 to 6 leaves on the topping, the growth period is longer, the amount of fertilizer required in the early and late growth period is relatively large, the demand for nutrients gradually increases after the seedlings are slowed down, and the demand for nutrients in the melon setting period and the expansion melon stage is the largest. Therefore, on the basis of applying sufficient basal fertilizer before planting, pumpkin should be topdressed in time during the growth period.

The purpose of pumpkin seedling fertilization is to raise seedlings, strengthen seedlings, and grow trees, and top dressing should be based on compound high nitrogen. Pumpkin seedling growth is small, generally does not need too much watering and fertilization, after transplanting and planting seedlings, if the seedlings are weak, can be slowed down within 7 days, combined with watering seedling water appropriately with 10% of dilute manure urine watering or per mu with water to apply compound high nitrogen for topdressing and seedling growth, good moisture, high soil fertility, vigorous growth of the plot, can be less topdressing or no topdressing, in order to prevent pumpkin seedlings from growing in vain.

When we fertilize the pumpkin, in fact, we have to fertilize it at the right time, so that the pumpkin will grow longer and fatter, longer and more tender, and the soil will be easier to absorb in the weather after the rain.

How to plant pumpkins, pay attention to these cultivation skills, and make pumpkins fragrant and sweet! Pumpkin is planted and cultivated.

Pumpkin likes organic fertilizer, and the amount of fertilizer and nutrient combination should be determined according to plant growth and soil fertility. For example, the growth point of the melon vine is thick and upturned, and the leaf color is dark green, so as to prevent the growth and transformation of the melon; If the leaf color is pale green or yellow, it should be fertilized in time.

In the early stage, nitrogen is the main body, and in the later stage, potassium and phosphorus are the main ones. In the 137 days from planting to seedling pulling, the uptake of nitrogen, phosphorus, potassium, calcium and magnesium increased slowly in the first time, and increased rapidly in the middle time, and the most significant increase was in the last time. Nitrogen fertilizer and potassium fertilizer were the most nutritious, followed by calcium, magnesium and phosphorus the least nutrients.

If you want to grow pumpkin for high yield, it is best to choose farmhouse fertilizer with appropriate calcium substance. Farm manure can choose chicken manure or pig manure. It is suitable for fully decomposed farmhouse fertilizer, not suitable for raw fertilizer

When we grow pumpkins, we should not use chlorine fertilizer, because it will affect the starch glycos, so that the sugar content is reduced, and we should not use cow dung. In short, pumpkin is most suitable for organic fertilizer with nitrogen, phosphorus and potassium compound fertilizer.

It is better to choose well-rotted farmhouse manure. It is best not to use fertilizers that contain chlorine. Scientific fertilization is needed in order to achieve high yields.

Pumpkin is not strict on the soil requirements, even relatively barren soil can be cultivated, because of its root system fertilizer absorption, water absorption ability, some difficult to cultivate vegetables can be cultivated on the land, sandy loam and loam soil pumpkin is the most suitable, the soil is fertile and nutritious is conducive to the formation of female flowers. The pH suitable for the growth of pumpkin is, the nitrogen content in the soil should not be too high, if the soil for planting pumpkin is too barren and thin, the lack of fertility will cause flower and fruit drop, and reduce the yield.

Pumpkin is one of the vegetables with the highest absorption of nitrogen, phosphorus, and potassium. The absorption of nutrients during the whole growth period is more potassium and nitrogen, calcium is in the middle, magnesium and phosphorus are less, each pumpkin absorbs nitrogen grams, potassium grams, calcium grams, phosphorus grams, magnesium grams or so, and each 1000 kg of pumpkin needs to absorb about kilograms of nitrogen, phosphorus pentoxide, potassium oxide.

1) Apply plantar fertilizer.

Although pumpkin does not have strict requirements for soil conditions, in order to obtain high quality and high yield, it is also necessary to apply a certain amount of base fertilizer when planting pumpkin, especially when planting pumpkin on barren soil, more organic fertilizer should be applied as base fertilizer. Generally, 4000 5000 kg of high-quality rotted farmhouse fertilizer is applied per mu of pumpkin, and then raked evenly after sprinkling evenly and then made a furrow to seed melon, if the fertilizer source is tight, it can also be fertilized in the furrow first, and 2000 3000 kg of rotted farmhouse fertilizer is applied per mu as the base fertilizer. In the south, 10 15 kg of calcium, magnesium and phosphorus fertilizer can be applied per mu to increase the content of calcium and magnesium.

2) Top dressing should be appropriate.

Pumpkin topdressing should be carried out according to its different growth stages, soil fertility and plant growth, and nitrogen fertilizer should be applied less in the early stage to prevent overgrowth. After the pumpkin seedlings are slowed down, if the seedlings are weak, the leaf color is light and yellow, it can be combined with watering and topdressing 1:3 4 light manure water (that is, 1 part of human manure and urine plus 3 4 parts of water), the amount of 250 300 kg per mu, top application of fertilizer, in the middle of plant growth, when sitting on one or two young melons, top dressing should be reapplied before sealing the ridge to ensure that there are sufficient nutrients.

Generally, 1000 1500 kg of manure water of 1:2 per mu is applied, or a ring ditch is opened around the root, high-quality well-rotted organic fertilizer is applied, and 10 15 kg of ammonium sulfate (or 7 10 kg of urea, or 15 20 kg of ternary compound fertilizer) is applied per mu. After the fruit begins to be harvested, 10 15 kg of ternary compound fertilizer is applied per mu to prevent premature plant senescence and ensure the yield in the later stage.

The intermittent phenomenon of pumpkin fruiting is that when the first fruit on the melon vine develops, the third or fourth melon produced later will stop developing and turn into melons or lose buds, and the female flowers that bloom again must be several days after the first fruit is harvested to bear fruit. The intermittent phenomenon of pumpkin fruiting is caused by the unbalanced nutrient distribution in the plant, and the fundamental reasons are low fertility, insufficient amount of fertilizer, and high-node flowers and fruits due to the lack of nutrients and melons. Secondly, after the pumpkin fruit begins to expand, if it rains continuously or the plant is diseased, a large number of leaves cannot grow normally, and the nutrient area is reduced, and the fruit will stop developing and turn into a melon. The methods of prevention are:

Apply plantar fertilizer, timely top dressing to ensure nutrient supply, spray potassium dihydrogen phosphate and manganese sulfate to improve the photosynthesis of leaves.

1. Apply basal fertilizer.

Because the pumpkin has a well-developed root system and strong ability to absorb fertilizer, it is necessary to turn 30 cm deep before winter and turn two plows in the next spring. 75,000 kg of well-decomposed high-quality organic fertilizer was applied per hectare, and it was sprinkled before turning the second plough or applied intensively in the sowing furrow. After ploughing and leveling, sowing furrows or planting furrows are made, and about 4,500 plants are planted per hectare.

2. Apply fertilizer to the plant.

After the pumpkin is transplanted and the seedlings are slow, if the seedlings are weak and the leaf color is light and yellow, it can be combined with watering and topdressing to apply fertilizer to the plant, and 3750 4500 kg of dilute manure water per hectare.

3. Apply fruit-promoting fertilizer.

When the plant enters the middle stage of growth and sits on 1 2 young melons, it should be reapplied before the closure of the fruit-promoting fertilizer, generally 15000 22500 kg of well-rotted thin manure water or cake fertilizer water per hectare. In case of drought during this period, it can be combined with watering, and 225 300 kg of compound fertilizer can be applied with water.

4. Late topdressing.

After the fruit is harvested, in order to prevent premature plant senescence and increase the yield in the later stage, a small amount of organic fertilizer can also be applied. If you do not harvest tender melons, but prepare to harvest mature melons, you do not need to top dressing in the later stage, only need to water or drain. Potassium dihydrogen phosphate can also be sprayed in the middle and late stages, 7 1 time in 10 days, and 2 3 times in a row.
