What can be used to increase the sweetness of greenhouse tomatoes?

There are five influencing factors for tomato sweetness and color change.

First, whether the trace elements are comprehensive**. Only ** nitrogen, phosphorus and potassium, lack of boron, calcium, magnesium, zinc, iron and other trace elements is not good.

2. Sufficient amount of sunshine accumulated temperature and a certain temperature difference. Long-term rain and lack of sunlight or the temperature difference between day and night is too small cannot complete the accumulation of sugar.

3. Reasonable leaf-to-fruit ratio. There are many friends who make tomato fruits turn color quickly, and they beat a large number of leaves in the middle and late stages, which is not right. If there are no leaves or too few leaves, photosynthesis will be poor, and the worse the photosynthesis, the worse the nutrient transport and sugar accumulation.

Fourth, appropriate application of nitrogen fertilizer and increase the application of soil miscellaneous fertilizer, organic fertilizer, biological fertilizer. Too much nitrogen fertilizer is not conducive to color change and sweetening, potassium fertilizer is mainly potassium sulfate, and excessive use of potassium nitrate should not be avoided. Increasing soil miscellaneous fertilizer, biological fertilizer and organic fertilizer can not only improve the rhizosphere environment of tomatoes and promote plant health, but also meet the needs of various elements for fruit expansion and sweetening.

Fifth, in the middle and late stages, moderate drought, soil water retention of about 50-60, air humidity of about 50% is conducive to the increase of tomato sugar.

It doesn't matter what kind of fertilizer is used to increase sweetness. Why isn't it sweet, that is, when the tomatoes are about to be sweetened, they are picked and sold for money. Because there are too many fruits.

The lower one is not picked, and the upper one does not grow, which affects the yield. If you want to be delicious and sweet, you must reach ten percent after the mouth. Sweet and sandy.

Then there is less watering when the spot color is sugared. Or no watering. The kind that is naturally red and good.

Sweet and delicious. The biggest block point is that it can't be transported. If it is shipped to the place where it is sold, it will rot.

No one is involved in buying and selling at a loss.

How canopy tomatoes maintain their taste and increase sugar content.

Supplement with trace elements. As we all know, the supplement of potassium fertilizer is very important during the fruiting period of tomatoes, but in addition to potassium fertilizer, trace elements have a greater impact on the taste quality. The addition of trace element fertilizers such as iron, manganese, and zinc is conducive to the synthesis of flavor substances and the improvement of sweetness.

Control the temperature difference between day and night. In spring, the greenhouse is easy to form a good temperature difference between day and night through air control, and the sweetness will increase when the temperature difference between day and night is 10-12 degrees Celsius. However, in winter and summer, it is difficult to maintain such a large temperature difference between day and night due to the external environment, so the sugar content will also be affected.

Control the frequency of watering, the amount of watering. Because tomatoes are continuous fruit setting type, water and fertilizer are needed to supplement each panicle fruit expansion stage, but large irrigation or only irrigation without fertilization will reduce the sweetness of tomatoes. Therefore, it is recommended to integrate water and fertilizer to supplement water and fertilizer.

Replenish nutrients at the same time, and the fertilizer dissolved in water is more easily absorbed by the root system, which improves the use efficiency of water and fertilizer and improves the quality of tomatoes.

Conclusion Controlling the temperature difference, supplementing micro-fertilizer in a timely manner, and integrating water and fertilizer topdressing are all effective measures to improve the sweetness of tomatoes. To supplement the content of organic matter, that is, to use organic fertilizer. If you want to save costs, you can ferment organic fertilizer by yourself.

Use organic fertilizer starter to ferment waste such as manure or straw into organic fertilizer.

Foliar fertilizers such as bika silicon-soluble potassium dihydrogen phosphate, superphosphate, boric acid or borax solution, zinc sulfate can be sprayed 2-3 times in a row, and sprayed once every 7 days or so, which can well improve the sugar content and taste of tomatoes. In particular, calcium and boron nutrition must be supplemented.

Isn't there a sweetener now? Most of them are sprayed with a field exacerbator, which can increase the sweetness. It's because the sunlight is not enough in the greenhouse, or the growth time is relatively short. You can use sweeteners to add some sweetness to him.

The yield of tomatoes planted in the side section of saline-alkali land is relatively high, and the sweetness of the fruit is relatively large. It is a handful of sugar and a round of trembling to transport Layu urea, such a ratio, add water for irrigation.

First of all, you can spray the page by Qingda potassium dihydrogen phosphate, and then spray it 2 or 3 times in a row, and spray it once every 7 days or so, so that you can improve the sweetness and taste of the tomatoes.

First, keep it hydrated.

Second, bee pollination or artificial pollination.

Third, there is plenty of sunlight.

Fourth, do not cut off the first leaves of tomatoes.

Fifth, cut off the buds to grow (there are also those that are not cut).

Sixth, it is mainly suitable for organic fertilizer.

Seventh, try to avoid insect medicine, pesticides, and fertilizers in the branching.

Eighth, add some boiled yellow beans to the roots for fertilizer.

9. Variety selection.

Control nitrogen fertilizer, apply more decomposed organic fertilizer, and pay attention to medium and trace element foliar fertilizer.

Tomatoes need to be supplied with sufficient water after entering the period of continuous fruit setting and fruit expansion.

In the middle and late stages, the old leaves, yellow leaves, diseased leaves, and shading leaves of the middle and lower parts of the plants should be removed in time to improve the ventilation and light transmission environment of tomato fruits and promote the effective accumulation of sugar.

Tomatoes are sweeter when eaten raw, and when ripe, they become sweet and sour.

Ingredients: tomatoes, eggs, salt, cooking oil, white vinegar.

Method 1Wash the tomatoes first and cut them into cubes.

2.Beat the eggs well, add a pinch of salt, and add two or three drops of white vinegar (so that the scrambled eggs are soft, good shape, and taste great).

3.Heat the oil in a pan, pour the egg mixture along the wall of the pan, wait until it is formed, use a spatula to cut into small pieces, and set aside.

4.Leave a little oil in the pan (try to put a little more oil when scrambling eggs, leaving a small portion of oil for fried tomatoes), pour in the tomatoes and stir-fry.

5.Wait until the juice of the tomatoes comes out, pour in the scrambled eggs and fry them together (the action should not be too large). (If you are afraid of acid, you can add some sugar and then take it out of the pot.) However, I just like this sour taste, super rice).

6.It is not recommended to put chicken essence or monosodium glutamate in this dish, as for why, you will know if you have tasted it.

Tips: Eggs are best not fed to chickens with feed, and eggs born by chickens that eat coarse grains are good in color, nutritious, safe and healthy.

It's very simple, just add a little sugar and you're good to go.

Foliar spraying and topdressing of potassium nitrate were used to reduce the amount of ammonium nitrogen fertilizer.

The role of potassium dihydrogen phosphate is to protect flowers and fruits, and to color and sweeten the puffed fruits, but in the later stage, due to our fertilization and management problems, the simple use of potassium dihydrogen phosphate can not meet the accumulation of plant nutrients.

In response to the above problems, after years of application and research on fruit color and sweetening, the technical teacher of Kaijin Technology has summarized a set of programs with good results, namely: potassium dihydrogen phosphate + calcium boron organic acid foliar fertilizer + glucose, these three together use the effect of fruit color and sweetening is obviously different, let's talk about why this combination:

We will not talk about the role of potassium dihydrogen phosphate for fruit dispansion and color improvement is good, boron participates in the synthesis of carbohydrates, and has a role in improving sugar synthesis and color change, calcium improves the hardness and toughness of the peel, so that the fruit has better stress resistance, and has an auxiliary role in the dispanning fruit coloring.

Glucose belongs to the monosaccharides, which are easier to be absorbed and utilized by plants, so that the sugar accumulation of fruits can be increased through the action of glucose, so that the fruit will be colored and sweetened by the supplement of boron calcium combined with phosphorus and potassium, and the key is that the cost of such a combination is not high, and it is safe and hormone-free.

Have you learned the above methods? Sometimes the problem of fruit color and sweetening is not very difficult to solve, make reasonable use of our commonly used potassium dihydrogen phosphate, and combine the boron-calcium foliar fertilizer that solves the problem of calcium and boron, which is very good for improving our planting effect, I hope it will be useful to everyone.

Flower and fruit protection: early use, can overcome the influence of low temperature, weak light and other environmental conditions, prevent flower and fruit fall, and achieve the purpose of mutual flower and fruit protection.

2. Sweetening and coloring: used in the middle and late stages, it can promote fruit expansion and supplement a variety of trace elements required for fruit growth, prevent fruit cracking, and increase fruit soluble solids by 2%. Improve the sugar content of the fruit, promote the color 10-15 days in advance, the color is deep and uniform, that is, the sweetening of the color is asked, and at the same time can increase the hardness of the fruit and prolong the storage period.

The following methods can be used: 1. Dilute 300 times the liquid for foliar spraying. 2. Dilute 500-1000 times of liquid to irrigate the roots. 3. Dilute 10-20 times to coat the stem.

First of all, starting from the soil adjustment, now the greenhouse planting rotation soil is overtired, has not been well repaired, so before planting must use organic fertilizer, microbial fertilizer such as Ao Nongle to condition the soil, improve the soil and increase soil organic matter.

Disease prevention should also be taken before planting. For example, in the use of microbial agents Diwang, lilac Penicillium, wilt litter to irrigate once, or high concentration spray once, this can reduce the pathogen and root-knot nematode in the soil, if you have had root-knot nematode can increase the concentration of Penicillium lavender, but also improve the soil, increase the beneficial bacteria in the soil, increase soil fertility.

Then the disease is prevented in advance, and the damage can be minimized by treating the disease. It is recommended that you can use Chinese herbal preparations as an annual medication regimen, which can increase the taste of tomatoes, increase yield, and eat tomatoes with the taste of childhood.

1. The slow seedling period after tomato planting in winter is in the cold season, and the greenhouse temperature is mainly suitable. It is conducive to the growth of tomatoes, and pay attention to adjusting the light and humidity in the shed, and spraying the new high-lipid film in time can effectively prevent the water on the ground from evaporating, and the moisture of the seedling body from transpiring, shorten the seedling period, so that the plants can quickly adapt to the new environment and grow healthily. 2. According to the growth needs of tomatoes, reasonable watering, fertilization, weeding, pest and disease control, at the same time, the old leaves and yellow leaves of the lower part of the plant should be removed and brought out of the shed for deep burial, and the new high-fat film is sprayed in the greenhouse to form a protective film to prevent and control the invasion of airborne pathogens.

3. In order to improve the fruit setting rate of tomatoes in greenhouses, it is generally sprayed before flowering, young fruit stage and fruit expansion period to enhance the quality of pollen fertilization, improve the cycle fruit setting rate, promote fruit development, prevent the occurrence of cracked fruit and deformed fruit, improve the quality of tomatoes, and produce bumper yields.
