Can saccharified boron fertilizer tablets for tobacco leaves be used on cucumbers

This is not allowed by reason, the fertilizer you use for tobacco is her fertilizer, how can it be used on cucumbers? If you use the same fertilizer for pumpkins, it's pretty much the same for cucumbers, and tomatoes, which is about the same fertilizer.

Boron is an essential element unique to higher plants, while animals, fungi and bacteria do not need boron. Boron can bind to sugars in the free state, making sugars easily cross the plasma membrane and facilitating sugar transport. The content of boron between the organs of plants was the highest in flowers, and the stigma and ovary were the highest in flowers.

Boron has an important effect on the reproductive process of plants and is closely related to pollen formation, pollen tube germination and fertilization. In boron deficiency, anthers and filaments atrophy and pollen is stunted. The phenomenon of "flowers but not fruits" in rape and wheat is related to plant boric acid deficiency.

When boron deficiency, the growth points of root tips and shoot tips stop growing, and a large number of lateral roots and lateral buds occur, and the growth points of the lateral roots and lateral buds behind them die, thus forming clusters. Brown rot in sugar beets, leaf curls in potatoes and fruit shrinkage in apples are all caused by boron deficiency.

Imagination! Before selecting the material, you can imagine the effect after putting it down. When I made steamed fish by myself, I felt that it was not enough to use cooking wine and vinegar to remove the fishy smell, so I had a whim to stuff the onion and garlic residue into the belly of the fish, use the taste of onion and garlic residue to wash away the fishy smell, steam for a few minutes and remove all the onions, and then put it down with cucumber slices to steam.

Finally, remove from the pan and drizzle with steamed fish soy sauce and cucumber juice. Sprinkle with chopped green onions. Sure enough, it was the same as I thought!

The fragrance of cucumber is in the flesh of the fish. It's awesome! So if you want to make a creative dish, you must be imaginative.

Only the unthinkable, there is nothing that cannot be done.

Saccharified boron fertilizer tablets can be used on cucumbers, but saccharified boron should be used specially.

First of all, before transplanting cucumber seedlings, kilograms of boron fertilizer are used as base fertilizer per mu, which has a good boron supplementation effect.

Secondly, flower buds begin to appear in cucumber seedlings.

It is recommended to spray foliar borax once every 10-15 days.

solution, and other amino acids can be combined at the same time.

Water-soluble fertilizer mixed spraying has a better effect.

Cucumber planting. Note: When spraying, all the leaves and buds should be evenly sprayed, so that there are water droplets dripping down at the beginning. It is recommended that the spraying time is 8-11 a.m. and 4-6 p.m., when the absorption and utilization rate of sprayed plants is high, and the effect of boron supplementation is also the best.

When applying basal fertilizer, about 1 kg of borax per mu should be applied to the base fertilizer, which can also meet the demand for boron mountain during the whole growth period of cucumbers. When the soil is dry, it is necessary to water in time, but it is necessary to pay attention to the amount, the moisture content of the soil is high, and the boron is easy to be lost, so drainage measures should be taken in the rainy season to avoid a large loss of boron. Fertilization should be carried out according to the fertilizer needs of each growth stage of the plant, and it is not advisable to apply a certain kind of fertilizer in the middle of the block, if there is a lack of boron in the later stage, the borax can be diluted with water and then sprayed with foliar fertilizer, which can quickly supplement boron.

In general, the soil in the eastern and southeastern vegetable areas of China is prone to boron deficiency. There are several reasons for boron deficiency in soils. One is that the boron content of the acidic parent material of the soil in such areas is low, such as red soil, yellow-brown soil, purple soil, etc.

The other is that the boron element in the soil parent material mainly exists in the form of minerals and tourmaline that are difficult to weather, resulting in a small amount of water-soluble boron. In addition, a high soil pH or a high content of organic matter in the soil will lead to a decrease in the amount of available boron in the soil, such as excessive application of lime in acidic soils, which will lead to a decrease in the available boron content of the soil. In general, soil organic matter should be the source of boron supply, but in the case of soil drought or low-lying terrain and poor drainage, the decomposition of organic matter is slow, and the fixed boron cannot be released, which will also lead to boron deficiency in the soil.

There are two main types of boron fertilizer applied in cucumber cultivation: borax (Na2B4O7·10H2O) and boric acid (H3Bo3). Among them, borax is the most used, which is white crystals or powders, soluble in hot water, and is mainly used for soil fertilization; Boric acid is a white powder, soluble in water, and is used as a foliar spray. Now there is also an imported boron fertilizer variety, called "Solubor" (composed of Na2B4O7·5H2O + Na2B10O16·10H2O), which can be well dissolved in cold water, suitable for soil application and foliar spraying, and the effect is good.

Boron fertilizer should be evenly spread and tilled into the soil before planting. Foliar sprays were sprayed at a slightly lower concentration at the seedling stage and slightly higher at the late growth stage. If the symptoms of boron deficiency have appeared in the field, it must be sprayed 2 or 3 times as soon as possible, and the effect is better.

The amount of boron fertilizer should not be excessive, more than 3 kg of boron fertilizer per hectare on acidic soil will cause cucumber plant poisoning, in addition, uneven application or sprinkling, local concentration will also cause some plant poisoning. The after-effects of soil boron fertilizer can generally last for 2 to 3 years. Generally, when the water-soluble boron content of the soil is less than milligram kg, the application of boron fertilizer has a good effect.

Boron fertilizer can not be mixed with urea, compound fertilizer and other fertilizers, easy to chemical reaction, boron fertilizer and urea are easy to deliquescent after mixing, and boron fertilizer and compound fertilizer mix not only increase the cost, but also has no fertilizer effect, boron fertilizer is mainly sprayed foliage, and compound fertilizer boron fertilizer and light phosphorus and potassium are best not used at the same time, and calcium fertilizer can, but pay attention to the use method. Boron fertilizer is easily fixed by the soil, while calcium has the property of compacting the soil. Therefore, if it is used at the same time, boron fertilizer needs to be sprayed on the foliar surface, and calcium fertilizer should not be too much, otherwise it will be lost.

Unless you're using a specially produced boron-calcium fertilizer. At present, many manufacturers have introduced advanced chelation technology, which can eliminate the interaction between boron and calcium ions, and specialize in the production of fertilizers that can supplement boron and calcium at the same time. For example, the refined boron calcium of Zhongzhi Company, does it refer to spraying?

It is true that boron fertilizer and calcium fertilizer have a certain antagonistic effect, and it is best not to use them together. If they are used together, they must choose a good level of chelation technology, and they must be diluted twice.

It is generally recommended to use it before flowering, and it can also be used when the fruit is just set, so that it can play a role in preserving flowers and fruits.<> Do not use it in the full flowering period of the plant, because in the full flowering period, the plant will be more sensitive to various fertilizers and sulfur together will make the chemical composition of boron very unstable, on the one hand, boron has an impact on the growth and development of crops, but if it is used with sulfur, it will be very bad for the plant, the growth of the plant has received problems, and it will lead to the phenomenon of fruit cracking.

Wheat post-emergence herbicide weeding method, through weed stems and leaves internal absorption conduction poisoning, inhibition of the top growth point, although the weeds do not die quickly, but also do not affect the efficacy of the drug, gradually will die of leaves, although the wheat field with herbicides is mostly selective, but after all, because of the wheat field spraying herbicides Although the impact on wheat is not too great, but after several years of my experience in spraying herbicides, spraying herbicides to wheat wheat seedlings will not grow in about 15 20 days.

Borax can not be mixed with alkaline fertilizers or pesticides in aqueous solution, nor can it be mixed with calcium fertilizers and magnesium fertilizers. After mixing in this way, an adverse reaction will occur, and borax will combine with calcium and magnesium ions to form a precipitate, which will not have the desired effect. If it must be mixed with compound fertilizer, etc., do a test first to see if there is a precipitate generated, if there is, it cannot be mixed.

Boron fertilizers cannot be applied together with fertilizers such as compound fertilizers and urea, and chemical reactions may occur. If it must be mixed with compound fertilizer, urea, etc., it is necessary to consider whether it will cause the loss of crop nutrients after mixing.

Mixed use, boron physiological weak acidity, in the foliar spraying application, some friends in order to save the labor cost of spraying, like to mix borax with other fertilizers to spray, can play a role in the purpose of "how fast and good to save", if it is not properly mixed, it will not play a good role, for example, borax can not be mixed with aqueous solution alkaline fertilizer or pesticides, and do not mix with calcium fertilizer, magnesium fertilizer. Because after mixing in this way, an adverse reaction will occur, and borax will combine with calcium and magnesium ions to form a precipitate, which will not have the desired effect. If it must be mixed with compound fertilizer, do a test first to see if there is a precipitate generated, if so, borax or boric acid is best sprayed alone, or mixed with potassium dihydrogen phosphate, because potassium dihydrogen phosphate is also weakly acidic, melts quickly in water, no residue, and borax mixed foliar spraying, can improve the utilization rate of fertilizer.

Cucumber is a boron-loving crop, especially in the flowering and fruiting stage. If boron fertilizer is insufficient at this time, it will affect pollination and fertilization, resulting in melon melting and falling melon, and reducing fruit setting rate; The light ones are easy to form deformed melons, such as curved melons, sharp-mouthed melons, pot-bellied melons, etc.; There may also be phenomena such as corked skin, rough and uneven appearance, and hollow inside, which affect the yield and commerciality of cucumbers, so it is necessary to pay attention to supplementing boron fertilizer during the flowering and fruiting period of cucumbers.

When cucumber seedlings are transplanted to 6 8 new leaves and flower buds begin to appear, boron fertilizer should be supplemented in time, and borax aqueous solution or boric acid aqueous solution should be sprayed once every 10 15 days, or 1000 times fluid boron aqueous solution, or 1000 times active boron aqueous solution, etc., mixed with 600 800 times amino acid composite micro-fertilizer aqueous solution and sprayed 3 5 times continuously.

Spray all leaves and buds evenly until water droplets begin to drip down. Boron fertilizer is most easily absorbed when sprayed at 8 11 a.m. and 16 p.m. at 19 p.m.

It may be possible, but if you want to increase the yield of cucumbers, you can use medium and micro fertilizer seedlings to make money, and the raw materials are selected from large domestic and international import enterprises to supplement the zinc, boron, molybdenum, copper and other trace elements required by cucumbers, promote flowers and fruits, and increase yield.

Description of saccharified boron tablets.

Saccharified boron fertilizer tablets are fertilizers, not pesticides, and cannot play a bactericidal role.

Saccharified boron fertilizer tablets are controlled by slow-release technology to control the slow release of saccharated boron in the tablets into the soil, which is absorbed by the crop roots and transmitted to the leaf cells, activating the expression of disease and insect resistance genes, thereby improving the ability of crops to resist diseases and insects, and can also effectively supplement crop boron, significantly improve the yield and quality of crops, and prevent and control the phenomena caused by boron deficiency, such as "flowers but not fruits", "fruits but not fruits", and "fruit deformities" caused by boron deficiency.

Saccharified boron fertilizer tablets are suitable for greenhouse and open-field vegetables, melons and other crops, such as: watermelon, cucumber, melon, cantaloupe, tomato, bean, eggplant, pepper, zucchini winter melon, strawberry, tobacco, etc.

Boron fertilizer insect tablets are reliable to a certain extent.

Under the condition of reasonable use of boron fertilizer insect control tablets, it will not cause any harm to the human body. When using boron fertilizer, if you are afraid that it will volatilize and affect people's health, you can wear gloves to do a good job of protection, do not touch it directly with your hands. Moreover, if the boron-watered plants are eaten, they should be washed twice before eating, and there will be no serious pesticide residue problems.

The above is the relevant information of boron fertilizer insect control tablets, I hope it will be helpful to you.

Boron is one of the essential nutrients for plant growth and development. According to the survey, 90% of the country's soil is boron deficient, of which more than 70% are seriously boron-deficient.

When boron deficiency is severe, the growth point of the plant stem tip is inhibited, the internodes are short, the growth of the growth point is stagnant, and even die. After the apical bud dies, the axillary buds germinate, and the lateral branches are clustered, forming large clusters of multiple heads. The root system is underdeveloped, the growth of the root tip is stopped, it is brown, the lateral roots are encrypted, and the root is swollen below the root neck, like the radish root.

The old leaves are thickened and brittle, and the leaf color is dark green and dull; The new leaves are shriveled, curled and lose green, and the petioles are shortened and thickened. The stems are shortened, and in severe cases, cracked stems and corks appear.

The flower buds fall off, the flowers are few and small, the seed setting rate is low, the fruit is stunted, often deformed, small and hard. For example, rape "flowers but not fruits", cotton buds but not flowers, peanuts with fruit but no kernels, celery crack stem disease, apple fruit shrinkage disease, etc. are all serious boron deficiency. Generally, a slight boron** deficiency may not show symptoms in the plant body, but there will be a significant yield increase effect after the application of boron fertilizer.

In other words, instead of waiting for crops to show symptoms of boron deficiency, boron fertilizer should be applied in advance.

Generally, when the soil water-soluble boron is less than milligram kg, boron fertilizer application has a good effect. In general, the soil application of borax does not exceed one kilogram per mu. However, basal boron fertilizer can be affected by factors such as soil pH, soil mineral composition, and organic matter content.

Boron availability is best when the pH is at it; When it is greater than 7, the availability of boron is reduced, so boron deficiency mostly occurs in soils with a pH greater than 7. Over-application of lime in acidic soils can also lead to boron deficiency.

Boron-sensitive crops are mainly leguminous and cruciferous crops, followed by sugar beet, tomato, cucumber, cauliflower, celery and other crops, and the effect is better after boron fertilizer application. After boron fertilizer is applied to the soil, the general validity period can be maintained for 2-3 years, and it is not necessary to apply it year after year.

At present, the main types of boron fertilizer are borax, boric acid, solubor, etc., of which borax needs to be dissolved in hot water above 40 degrees Celsius, and then mixed into a dilution of the required concentration. In order to prevent boron poisoning, the concentration of the general use can not exceed the times of the liquid), and the times of the liquid are generally used). Because its solution is an alkaline reaction, if it is mixed with other drugs and fertilizers, it should be tested in advance to avoid adverse reactions.

In the peak flowering period of crops and the high temperature period at noon, boron fertilizer should not be sprayed to avoid fertilizer damage.

Soil application of borax should be mixed with organic fertilizer or dry fine soil and then applied in ditching or holes, but boron fertilizer can not directly contact seeds or seedlings, so as not to affect seed germination and seedling growth. When the dosage per mu exceeds kilograms, the seedling emergence rate will be reduced, resulting in the phenomenon of dead seedlings.

Foliar spraying of borax is generally less than 50 grams per mu. The spray should be uniform, and if it rains within 6 hours, it should be sprayed. Boron deficiency is aggravated under arid conditions, so boron supplementation should also be combined with watering and other measures to ensure effectiveness.

For commercially available boron fertilizer preparations, they should be applied reasonably in accordance with their instructions for use.
