What fertilizer is used to grow watermelons with the sweetest watermelon?

Many farmers are very fond of planting watermelons, and if they want watermelons to grow big and sweet, they should also choose the right fertilizer in the planting process. You can choose nitrate nitrogen fertilizer, which can allow watermelons to better absorb nutrients during the growth process, and it is best not to choose ammonium nitrate.

fertilizer, because this fertilizer affects the watermelon, for the element calcium.

and magnesium absorption, excessive use will easily make watermelon stunted. Phosphorus.

It can promote the development of roots, and it can also increase the sugar content of the pulp, which can make the taste of watermelon more crisp and sweet. If the watermelon lacks phosphorus during development, it will bloom very slowly and will fall fruit easily. <>

Nitrogen fertilizer is very necessary, in the process of watermelon growth and development, nitrogen is indispensable, nutrients can make the leaves and stems grow strongly, potassium fertilizer can also be appropriately sprinkled with some can improve the toughness of the vine, but also can increase disease resistance. If the watermelon is deficient in potassium during development.

In the fruiting period, it is easy to affect the transport and synthesis of nutrients. <>

Growing watermelons requires nitrogen, phosphate, potassium, and calcium nitrate, which can ensure the healthy growth of watermelons and sweeten the pulp. In addition to these fertilizers, some trace elements also need to be supplemented.

This is good for the health of the body. You can also provide sufficient nutrition for watermelon with base fertilizer, because the demand for fertilizer for watermelon in the growth cycle is also relatively strong, so you must fertilize it in time, so as to avoid affecting the development of watermelon. <>

In the process of fertilization, it is also necessary to master the time, so as to avoid affecting the quality of watermelon, and you can choose to spray some potassium dihydrogen phosphate appropriately during the ripening period.

When mixed with borax, it can also increase the sugar content of watermelon, and you can choose to spray it once a week. But be sure to avoid potassium chloride.

Fertilizer, which can make watermelon taste worse.

Watermelon likes nitrate nitrogen fertilizers such as calcium nitrate, but try to use less ammonium nitrate, because it has a certain impact on the absorption of calcium and magnesium by plants, and excessive ammonium nitrogen is easy to cause fertilizer damage to plants. Phosphorus can promote the development of watermelon roots, increase the sugar content of watermelon pulp, and make watermelon taste sweeter. If the watermelon plant is deficient in phosphorus, it will delay the flowering of the watermelon and it is easy to drop flowers and fruits.

Potassium fertilizer can promote the strength and toughness of plant vines, improve wind resistance and disease resistance. Potassium deficiency can reduce the stress resistance of plants, especially during the fruiting period of watermelon, which can hinder the synthesis and transport of nutrients, resulting in slow fruit set and small fruits.

You can use peanut bran, which can increase the moisture and sweetness, which is a better way to use, or a good increase in the delicious taste.

I think the watermelon you grow with potassium fertilizer is sweeter because this fertilizer can provide a certain amount of moisture to the soil, which will make the watermelon grow the best.

If you want watermelon to be as sweet as honey, the crown of fertilizer is cake fertilizer" This is the experience summary of many old farmers in the process of planting watermelon. Cake fertilizer is mainly the oil residue of oil crops, common bean cake, sesame cake, rapeseed cake, peanut cake, sunflower cake, etc., cake fertilizer has a higher nitrogen content, but also contains more phosphorus and potassium, and vitamins, because the cake fertilizer nitrogen is mainly in the form of protein, phosphorus is mainly lecithin, phytic acid form, potassium can be dissolved in water, so it can be directly absorbed by crops, the effect is significant. Cake fertilizer is rich in nutrition, fertilizer effect is long-lasting, cake fertilizer can significantly improve the quality of watermelon, make watermelon sweeter, as a base fertilizer application to fully rot, generally 100 kg per mu of watermelon field can be applied.

The application of microbial fertilizer, phosphorus and potassium fertilizer can also increase the sugar content of watermelon. Or spray watermelon in the early flowering stage and sitting stage of watermelon, and spray sweetening solution to the foliar surface of watermelon in the middle and late stages of watermelon growth.

Urea must not be selected for fertilization, and organic fertilizer or compound fertilizer must be chosen when fertilizing, which can play a role in improving yield and can also improve the quality of crops.

When planting watermelon, whether the fertilizer can be applied reasonably will not only have an impact on the yield, but also have a certain impact on the taste of the watermelon. So, what fertilizer is used to grow watermelons that is big and sweet? The details are as follows:

1. What fertilizer is good to apply when planting watermelon if you want to be sweeter.

When planting watermelons, if you want to raise watermelons with a sweeter taste, you should choose the most suitable high-quality varieties according to the local soil and climate, so that the watermelons will taste better.

In addition, it is necessary to fertilize the watermelon reasonably, which is more conducive to the accumulation of sugar in the watermelon. When fertilizing watermelon, the base fertilizer should choose to apply more nitrogen fertilizer and potassium fertilizer, less phosphorus fertilizer, nitrogen fertilizer can promote the growth of watermelon, potassium fertilizer can promote watermelon expansion, and increase the sweetness, we can choose to apply potassium dihydrogen phosphate to it.

When the watermelon grows in the later stage, it should also be reasonably topdressed, and when topdressing, it is not only necessary to add elements such as nitrogen, phosphorus and potassium, but also to supplement it with zinc, boron, manganese and other trace elements, which will have a certain impact on the taste of watermelon, and reasonable use will make the taste of watermelon better.

2. Comments: In the process of planting, watermelon should be fertilized according to its growth. If you want to make watermelon sweeter, in addition to choosing the right variety, you should also fertilize it reasonably.

Watermelon has a greater demand for nitrogen, phosphorus and potassium in the early stage of growth, and potassium has a certain effect on increasing sweetness. In the later stage of growth, it should also be reasonably supplemented according to the growth of watermelon.

Organic fertilizer. Watermelon chooses organic fertilizer as the base fertilizer, and the fertilizer effect is long and lasting, so organic fertilizer is definitely indispensable. Generally, the manure organic fertilizer of the farmhouse is a good choice, but it must be rotten, otherwise it is easy to burn the seedlings.

It is also a good choice if you have cake fat, such as soybean meal and peanut cake, of course, the effect will be better if it can be rotted. Organic fertilizer has a long effect and is a good base fertilizer for watermelon.

Use of potash fertilizers.

As a type of crop with high sugar synthesis, watermelon has a very large demand for potassium fertilizer, which is conducive to metabolism, carbohydrate formation and accumulation. Greatly improve the quality of watermelon and increase the sugar content. After watermelon enters the fruit-setting stage, it is mainly reproductive growth, so a large amount of potassium fertilizer should be supplemented.

Even potassium dihydrogen phosphate can be selected as a foliar fertilizer spray. Nitrogen, phosphorus and potassium fertilizers can be used appropriately. Especially for the use of potassium chloride in watermelon, it can be used in the early stage, but it should not be used more, and potassium chloride should not be used in the later stage.

Too much chlorine will affect the accumulation of sugar and affect the quality of watermelon.

Pay attention to boron fertilizers. Boron fertilizer helps watermelon flower and fruit set, and proper application of boron fertilizer can effectively prevent the hollow of watermelon and the problem of excessive watermelon skin. It is very helpful to increase the yield of watermelon and improve the quality of watermelon.

This is especially the case for boron-deficient plots. As a trace element, although the demand is not large, it is also indispensable.

Foliar fertilizer. In the period of watermelon fruit expansion, it is necessary to apply foliar fertilizer, especially pay attention to the use of potassium dihydrogen phosphate, spray once every other week until ripe, and even when spraying, add a little sucrose or glucose to the solution, which will effectively increase the sweetness of watermelon. In addition, spraying borax (concentration) can also increase sweetness.

Select high-quality seeds with high yield and full grains for soaking and germination, and sow them into the soil after most of the seeds are exposed.

It is advisable to choose sandy loam soil with deep soil layer, loose and fertile soil, convenient drainage and irrigation, and cultivate fields that have not been planted with melon crops within 5 years of dry land and paddy fields within 3 years. After selecting the land, turn it deep and apply sufficient base fertilizer, and use high furrow planting, wide furrow rice, and narrow furrow rice. The wide furrow can be planted on both sides of the furrow, the melon vine can be climbed on both sides, and the melon vine can be planted in the middle on both sides, and the narrow furrow can be planted on one side of the melon vine to climb on one side.

The seedlings of early-maturing watermelons are about 1 month old and can be planted after growing 2-3 true leaves. Medium-ripening watermelon seedlings can be planted at an age of 20-25 days and late-ripening watermelons at a seedling age of 7-10 days. 2 rows of wide furrows and 1 row of narrow furrows.

Generally, the three-vine pruning method is adopted. When the main vine is 8-9 leaves, the main vine and two strong side vines are selected, and the rest of the sub-vines and grandchildren are all removed. Pruning should not be carried out on rainy days to prevent the spread of diseases.

When the vine grows to about 50 cm, combine the pruning with soil to press the vine, and then press it again at an interval of 3-4 knots, and press each vine 2-3 times to evenly arrange the melon vine.

If you want watermelon to be big and sweet, you need to think carefully about the use of fertilizer. Calcium and potassium fertilizers are essential for adding flavor to the elements. Rational use of organic fertilizer. Trace element. The variety of watermelon is also important.

This watermelon is generally made of bulking hormone, which can make the watermelon grow very big, but for sweetness, it should be sprayed with cyclamate, so as to make the watermelon sweet.

Apply enough powdered organic fertilizer, about tons per mu, to prevent and control pests and diseases in advance. If the management keeps up, there will be no problem, find an acre of comparative test, from input to output, quality and yield to make a synchronous comparison, the effect is remarkable.

If you want watermelon to be delicious, first of all, before planting melons, first use farmhouse fertilizer to fertilize the field half a year in advance, and then use peanut cake to fertilize sesame oil residue, rapeseed oil residue and the like, on the whole, even if your watermelon is not particularly large, but it is definitely very sweet.

Watermelons need to be reasonably applied with organic fertilizers, chemical fertilizers and other fertilizers to be big and sweet.

It's best to use farmhouse manure,, and cow. ...The fertilizer period is long, and the melons and fruits are good.

The fertilizer used to grow watermelons is basal fertilizer, and before planting, mixed with rotted farmhouse fertilizer in the soil can accelerate germination. During the seedling growth period, fast-acting fertilizer can be applied to the soil, which can accelerate the growth of seedlings. When the watermelon vine grows, urea, calcium fertilizer, etc. need to be applied, and farmhouse fertilizer and compound fertilizer can be applied during the fruit period, which can make the watermelon have sufficient sugar and good taste.

1. Base fertilizer

Watermelon is sweet, juicy and refreshing, and is a common fruit in summer. The germination and growth of watermelon are inseparable from the irrigation of fertilizer, but many people do not know what fertilizer to use to plant watermelon, planting watermelon first needs base fertilizer, mixing rotten farmhouse fertilizer in the soil can effectively promote the growth of watermelon.

2. Promote seedling fertilizer

Seedling fertilizer is the fertilizer applied when the seedlings grow 4 or 5 leaves after watermelon transplanting, and double enhancers can be applied at this time, which can effectively accelerate the growth of seedlings, so that the watermelon has a high sugar value and sufficient water. A small amount of fast-acting fertilizer can also be applied, which can also effectively accelerate the growth of seedlings.

3. Promote vine fertilizer

After the seedlings grow 40 cm, urea, calcium and potassium fertilizers can be applied to the soil, which can effectively promote the rapid growth of seedlings for climbing vines, accelerate leaf growth, accumulate nutrients, and accumulate energy for flowering and fruiting.

4. Puffed melon fertilizer

During the flowering and fruiting period of watermelon, puffed melon fertilizer can be applied, which can make the watermelon large and full, with high sweetness and rich juice. At this time, you can apply compound fertilizer based on farmhouse fertilizer, which contains more organic matter, which can promote the rapid growth of watermelon and increase the yield of watermelon field.

Watermelon planting with organic fertilizer, such as oil residue, can make watermelon sweeter.

On the basis of the application of organic fertilizer, it is better to apply potassium sulfate compound fertilizer and calcium fertilizer. When cultivating, basal fertilizer should be applied, and rotted farmhouse fertilizer should be selected. After the seedlings are planted, they should apply seedling fertilizer, and double additives can be selected, which can promote the growth of seedlings.

When it grows to 40 cm, it is necessary to apply urea, potassium and calcium fertilizers in time to promote the rapid growth of seedlings. When it begins to bloom and bear fruit, it is necessary to apply puffed melon fertilizer, and choose compound fertilizer or farmhouse fertilizer.

Watermelon planting note:

1. Reasonable irrigation.

The watermelon in the puffing period needs enough water to grow, but the irrigation must be appropriate and even, you can irrigate once every 5-7 days, to keep the soil dry and wet, if the soil is dry and then wet, it is easy to crack the melon, so it is important to water with small water to keep the humidity uniform.

2. Reasonable fertilization.

When planting watermelon, the fertilization is too blind, the amount of fertilizer exceeds the standard, and the reasonable fertilization cannot be achieved, usually the potassium fertilizer is not enough, and the nitrogen fertilizer exceeds the standard. In addition, when fertilizing, the quick-acting fertilizer is applied excessively, and the amount of organic fertilizer is insufficient or the organic fertilizer is not used at all, so that after planting for several years, the phosphorus content in the soil exceeds the standard, and the nitrogen and potassium content is insufficient.

3. Pruning and leaving fruits.

Watermelon can be pruned in three or four vines, such as tornadoes can be pruned with three vines, and extra-large Jingfeng Mibao and Jingfeng Mibao No. 2 can be pruned with four vines, leaving 1 standard melon for each plant, preferably about 1m away from the roots.

The distance is close, the melon is small, the yield is low, and the crooked melon and excess melon should be removed. After the fruit grows to a certain size, it is necessary to turn the melon in time, pay attention to the growth direction of the watermelon, and turn one-third of the watermelon every time the melon is turned.

4. Proper ventilation.

It is necessary to grasp the ventilation time during the melon expansion period, and ventilate when the greenhouse temperature is higher than 28, and end the ventilation when the greenhouse temperature is lower than 26. Specifically, according to the growth of watermelon in the greenhouse, as well as the weather conditions outside, when the watermelon grows vigorously, the ventilation time should be extended, which can control the growth, and when the growth is weak, the ventilation time should be appropriately shortened to promote the growth.
