Can urea be used as flower fertilizer sa, can urea be used as flower fertilizer

OK. Fermentation method: You can use a large plastic beverage jar to fill the urine, do not fill it, seal it, let it ferment for three months before use, and use it according to the amount of water (depending on the growth period of the crop, generally 50% is fine).

Note that urine is nitrogen fertilizer, long leaves; Pay attention to environmental sanitation when using it in the city, and do not apply fertilizer during the day.

Human urine is a kind of high-quality compound fertilizer that does not cost money, and every 1000 kg of fresh urine is equivalent to 25 kg of standard nitrogen fertilizer, 9 kg of superphosphate, and 4 kg of potassium sulfate.

The organic matter in the urine is mainly soluble organic matter, in the form of urea.

is the most, and the rest is a small amount of uric acid.

Hippuric acid has the most inorganic components of table salt, followed by phosphate, ammonium and various trace elements.

Wait. It can be seen that urine contains a more comprehensive composition of nitrogen, phosphorus and potassium, which is a good organic fast-acting fertilizer, and is often used as top dressing for flowers and trees.

1. Nitrogen fertilizer (to promote the flourishing of branches and leaves): such as sesame residue paste, residual beans and peanuts, human urine, etc.

2. Phosphate fertilizer (to promote bright flower color and fruit hypertrophy): such as smashed minced meat and bones and minced fish bones, fish bones, fish scales, and rice washing water after smashing and fermenting with water.

Wait. 3. Potassium fertilizer (to promote strong root system): such as plant ash.

Fresh urine is the excrement of the human body, and it cannot be used directly, and it is really good urine for flowers and plants. After natural fermentation, heat will be generated during fermentation, and this heat will burn the root system of the plant, so the manure needs to be fermented before it can be used as fertilizer.

The use of urea as an orchid fertilizer must be noted.

Urea is also known as nitrogen fertilizer.

Nitrogen fertilizer mainly promotes the flourishing of trees, increases chlorophyll and enhances vegetative growth. Too much nitrogen fertilizer will lead to soft tissues, long stems and leaves, susceptibility to pests and diseases, and reduced cold tolerance.

Without nitrogen fertilizer, the plant is thin, the leaves are yellow-green, the growth is slow, and the flower cannot be flowered.

Nitrogen fertilizers include animal nitrogen fertilizers and plant nitrogen fertilizers: human manure, horse, cattle, sheep, pig manure, fish fertilizer, horseshoe and other animal nitrogen fertilizers. Sesame residue, soybean cake, rapeseed cake, cottonseed cake and other plant-based nitrogen fertilizers.

The above two types are organic fertilizers. Mineral nitrogen fertilizer is also known as inorganic fertilizer or weighing. Ammonia sulfate, ammonia nitrate, urea, ammonia, etc., are all fast-acting nitrogen fertilizers, which are usually used as root top dressing, such as often used as root fertilization, which is easy to make the soil compact.

Urea can be used as flower fertilizer, it is a fertilizer with the highest nitrogen element, can maintain foliar luster, can also adjust the amount of flowers, suitable for all crops and soil, can be used as base fertilizer and top dressing, sometimes also used as seed fertilizer. When urea is used as flower fertilizer, it cannot be used as a single fertilizer, and should be used in combination with other organic fertilizers or compound fertilizers, so as to meet the growth needs of flowers and plants.

Urea is used as flower fertilizer.

Urea can be used as flower fertilizer, suitable for all crops and soil, suitable for base fertilizer and top dressing, and sometimes used as seed fertilizer, after use, it can make the branches and leaves grow very luxuriantly.

Urea is directly used as flower fertilizer.

Urea can not be directly used as flower fertilizer, its concentration is too high to easily burn the roots of the plant, dilute it with water before using a good nucleus, the ratio is about 1:5000, urinary lead will make the seeds lose the ability to germinate, and may even harm the seedlings, so do not use urea on seedlings and seeds.

What kind of flowers are urea suitable for.

Urea is now a fertilizer with the highest nitrogen content, which can be applied to most plants, such as pothos, fortune tree, sunflower, etc., can maintain foliar luster, and can also adjust the amount of flowers, such as peony flowers, roses, white palms, etc.

Urea is used as flower fertilizer.

1. To make urea fertilizer, you can use a large beverage plastic tank to seal the urea, let it ferment to three months before you can use it, and use it with water according to the amount of water, generally with 50% of the water friends round digging on it.

2. When urea is used as flower fertilizer, it cannot be used as a single fertilizer, but should be used in conjunction with other organic fertilizers or compound fertilizers, so as to meet the growth needs of flowers and plants.

Urea is used as flower fertilizer.

Urea can be used as flower fertilizer, suitable for all crops and soils, can be used as base fertilizer and top dressing, sometimes can also be used as seed fertilizer, after use, it can quickly accompany the growth of branches and leaves.

Urea is directly used as flower fertilizer.

Urea cannot be used directly as a flower fertilizer. Its high concentration can easily burn the roots of plants. Dilute with water in a ratio of approximately 1:5000 before use. Urea can make the seeds lose their ability to germinate and may even harm the seedlings, so do not use urea on the seedlings and seeds.

What kind of flowers are urea suitable for.

Urea is currently the fertilizer with the highest nitrogen content. It is suitable for most plants, such as pothos, rich tree, purple-backed geranium, etc. It can maintain the luster of the leaves and adjust the amount of flowers, such as peonies, roses, white palms, etc.

Urea is used as flower fertilizer.

1.To make urea fertilizer, you can seal the urea in a large plastic beverage tank and let it ferment for three months before it can be used. Add water according to the amount when using, generally 50% water.

2.When urea is used as flower fertilizer, it should not be used as a single fertilizer, but should be used in combination with other organic fertilizers or compound fertilizers to meet the growth needs of flowers.

<> urea can fertilize the flowers. Precautions for the use of urea: If the urea concentration is too high, it is easy to burn the roots of the rotating plant, dilute it with water before use, and the proportion is 1:

around 5000; After pouring urea, the beam bridge cannot be watered directly; Urea can make the seeds lose their ability to germinate, and may even harm the seedlings. Urea cannot be used as a fertilizer alone, but should be used in combination with other organic fertilizers or compound fertilizers.

1. Yes, urea may be used as foliar fertilizer, generally when it is used as root fertilizer, it is best to apply it when it rains or when the snow melts. Urea is a short-term fast-acting fertilizer, and the fertility is not long-lasting.

2. Urea, also known as carbamide, is a white crystal. One of the simplest organic compounds. Diamide of carbonic acid with the molecular formula H2NCONH2 (Co(NH2)2).

The main nitrogenous end product of protein metabolism in mammals and some fish. It is also the nitrogen fertilizer with the highest nitrogen content at present. As a neutral fertilizer, urea is suitable for a wide range of soils and plants.

It is easy to preserve, easy to use, and has little damage to the soil, and is a chemical nitrogen fertilizer that is currently used in large quantities. Ammonia and carbon dioxide are used in industry to synthesize urea under certain conditions.

Put the fertilizer in a water bottle with a little water, melt it and pour it into the pot.

How to fertilize the flowers planted outdoors: sprinkle them on the roots of the flowers and trees and water them.

Do not spray at high concentrations.

Not to be administered alone.

Urea should be applied in combination with organic fertilizers, phosphorus, potassium fertilizers and trace element fertilizers.

The rate of conversion of urea in the soil depends mainly on the soil temperature, and under normal circumstances, all urea applied to the soil will be converted to ammonium nitrogenUses of urea

It can be used in large quantities as a raw material for the production of melamine, urea-formaldehyde resin, hydrazine hydrate, tetracycline, phenobarbital, caffeine, reduced brown BR, phthalocyanine blue B, phthalocyanine blue BX, monosodium glutamate and other products.

1.Adjust the amount of flowers

In order to overcome the size of the apple field, in the small year, 5-6 weeks after flowering (the critical period of apple flower bud differentiation, the growth of new shoots is slow or stopped, and the nitrogen content of leaves is declining), foliar spraying urea aqueous solution, spraying twice in a row, can improve the nitrogen content of leaves, accelerate the growth of new shoots and inhibit the differentiation of flower buds, so that the amount of flowers in the big year is suitable.

.Flowers and fruits are thinned

The flower organ of the peach tree is more sensitive to urea but the response to the surface is more slow, therefore, the foreign urea was used to carry out the flower and fruit thinning test on peach and nectarine, the results show that the flower and fruit thinning of peach and nectarine, need a large concentration (in order to show a good effect, the most suitable concentration is 8%-12%, within 1-2 weeks after spraying, that is, the purpose of thinning flowers and fruits can be achieved. However, under different soil conditions, the response of different periods and different varieties needs to be further tested.

3.Rice seed production

In hybrid rice seed production technology, in order to improve the outcrossing rate of the parent parent and increase the seed yield of hybrid rice or the number of sterile lines, erythoxin is generally sprayed to reduce the degree of neck wrapping of the female parent or to make it completely withdrawn. Or spray the parent to regulate the growth of the two and synchronize the flowering period. Because gibberellin** is more expensive, it is expensive to produce seeds with it. People used urea instead of gibberellin for experiments, and used urea at the peak booting stage and the first panicle stage (20% heading), and its propagation effect was similar to that of gibberellin, and did not increase plant height.

4.Pest control

With urea, laundry detergent, water 4:1:400 parts, stirring and mixing, it can prevent aphids, red spiders, cabbage insects and other pests on fruit trees, vegetables and cotton, and the insecticidal effect is more than 90%.

The method of applying urea to flowers is:

1. Apply 10-20 grains (particle diameter 1mm) each time, and then water once, the amount of water is not large, and the soil can be moistened.

2. The fertilization time is 15-20 days apart.

3. If urea granules with a particle diameter of 2-3mm are applied, the dosage will be halved each time.

Urea fertilizes potted flowers, puts the fertilizer in a water bottle, melts and pours it into the pot. Be careful not to put too much.

Fertilize the ground planted flowers and trees, sprinkle directly to the roots of the flowers and trees, and water them. Fertilize appropriately according to the size of the flowers and trees, and don't put too much. Prevent burning roots!
