What is the correct way to apply boron? The correct way to use boron fertilizer

Foliar spraying at the late seedling stage (before and after flower bud differentiation) and the budding stage (15 to 30 cm in height) are the key periods for boron spraying, and boron fertilizer aqueous solution should be sprayed once. If borax is used, dissolve it in 40 warm water and then dilute it with water.

There are two ways to use boron fertilizer correctly: soil application and foliar spray.

1. Soil application: For reasonable soils with low boron content, you can choose to apply a soil hood to use slow-setting particulate matter boron fertilizer, such as Hefeng particulate boron 200-400 grams mu or more abundant particulate matter boron 800-1000 grams to increase soil fertilizer time. When planting grain crops, stir with organic fertilizer, organic fertilizer or an appropriate amount of dry fine soil sufficiently for bottom fertilizer hole application or strip application, and minimize contact with seeds.

2. Foliar spraying: Foliar spraying boron fertilizer can be flexible and moderately filled according to the development status of crops, and has the advantages of saving fertilizer, reducing environmental pollution, and fast absorption by plants, which is a common boron application method. It can be sprayed from both sides of the foliage, but because the vent is on the back of the foliage, the effect of backside spraying is obvious.

Foliar boron sprays should be applied moderately and appropriately according to the reproductive growth or reproductive growth characteristics of crops.

Precautions for the use of boron fertilizer

Boron fertilizer is directly related to the growth and development of crop reproduction and leakage organs, and should be used as soon as possible in the spraying stage. At the same time, it is highly recommended to spray new boron fertilizers with high efficiency and high absorption capacity by integrating various factors such as agricultural product quality, safety, ecological environmental protection and energy conservation.

Boron has poor ability to operate in the body of green plants, so it is advisable to spray it several times. If the crop is out of balance and is deficient in boron deficiency symptoms, boron fertilizer can be used in combination with watering, boron fertilizer can also be dissolved in human feces and urine, or it can be mixed with chemical fertilizer and diluted or applied with water, generally choose liquid boron fertilizer, the amount of use per mu is 150 grams. It can be used as a base fertilizer or as a top dressing in the early and middle stages of crop growth.

Hello, dear. The acidic red soil in the south is a boron deficiency area, including red soil, brick red soil, red soil, yellow soil, purple soil and calcareous soil. The area of boron deficiency in the soil developed in the northern loess region is also large.

Calcareous soils containing free calcium carbonate and poorly drained meadow soils are also susceptible to boron deficiency. The cut-off value for available boron deficiency in the soil is less than milligram kg. Boron-sensitive crops are mainly leguminous and cruciferous crops (e.g. oilseed rape, peanuts, soybeans, etc.), followed by sugar beet, fruit trees, sugar cane, vegetables and cotton.

Cereal crops such as rice, wheat, and corn are less sensitive to boron. The application of boron fertilizer has a significant effect on the prevention and control of the symptoms of "buds but not flowers" of cotton, "flowers but not fruits" of rapeseed, and "falling flowers and fruits" of fruit trees. Boron fertilizer has the effect on crop flowering and fruiting, accelerating carbohydrate transport in the body, enhancing photosynthesis, and forming nodules of leguminous crops, which can improve the drought and cold resistance of crops, and is conducive to preventing physiological diseases of crops.

Borax varieties include borax and boric acid, and borax is commonly used. The fertilization method is mainly foliar spray. The borax or boric acid solution used is sprayed about 50 kg per mu, sprayed 2 3 times, and rape is sprayed in the late seedling stage, the sprouting stage, and the early flowering stage.

Fruit trees are sprayed at the budding stage, flowering stage, and young fruit stage. It should be noted that crops need an appropriate amount of boron and an excess, the scope of poisoning is very narrow, and the boron effect has an after-effect, the dosage should be strictly controlled, evenly applied, and the fertilizer effect can last for 3 5 years at a time, so as to prevent excessive application of poison.

Summary. Hello, choose instant boron fertilizer to improve utilization rate and avoid toxicity. It can be used as a base fertilizer, which can be mixed with farm fertilizer and chemical fertilizer, or it can be used alone.

When sowing, boron fertilizer solution is poured in the sowing furrow or planting hole, and watered with water or top dressing with water during the growth period. s2

If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress. Finally, I wish you good health and a good mood!

Summary. Dear, it depends on how you use it, if it is foliar spray wet, for rape, cotton rice and the like, generally, one kilogram mixed with water 500 700kg, and then evenly sprayed. If it is soil bottom fertilizer, generally use 8 kg per mu to fully stir with the soil. . .

If you spray foliar fertilizer for fruit trees, how much boron fertilizer should be used for a bucket of water, what season to spray, and how many times to spray. If you apply how much boron fertilizer is used for a fruit tree, what is the appropriate time to apply it, and how many times a year?

You can squirt at a scale of 1:1000.

Scale 1:1000.

That is to say, one gram of boron fertilizer, add 1000ml of water, or 800ml of water, and spray its pages.

Use 1 2 times a year, you can spray before flowering and once before the fruit swells.

The sprayer is loaded with 30 pounds of water, how much boron fertilizer is used?

15,000 grams of water, then you use 15 to 20 grams of boron fertilizer.

If you apply basal fertilizer to each fruit tree, how much boron fertilizer to use, and when to apply it.

Large trees are about 100 g, about 50 cm from the roots, and about 60 g from small trees, before flowering in spring, and before fruiting.

Unused, is it a liquid or a powder?

Can be used granules.

What about spraying? In the case of spraying, it is sprayed on the foliage, which can be diluted at a ratio of 1:800.

In the plots with boron deficiency soil, the application of boron fertilizer has a more obvious effect on increasing yield. There are several main reasons for the lack of fertilizer in the soil, one is that soil acidification, or the use of lime is large, which will lead to soil fertilizer deficiency. Second, with heavy cropping, boron in the soil gradually decreases.

Third, when the soil is dry or humid, the use of chemical fertilizers all year round will lead to low boron utilization rate. Spraying boron fertilizer during the flowering period, such as planting beans, when boron deficiency falls flowers and pods, if boron fertilizer is sprayed during the flowering period, it will not achieve the effect and will affect pollination.
