1. The role and efficacy of Urea Fertilizer

Urea is a type of nitrogen fertilizer. It is a typical amide nitrogen fertilizer with a nitrogen content of 46%. It is also the highest nitrogen -containing nitrogen fertilizer. It is suitable for various soils and crops. It has a wide range of applications. So what are the effects and effects of Urea?

1. Promote crop growth

Nitrogen in Urea is one of the nutritional elements necessary for crop growth and development.And if the crops are deficient in nitrogen fertilizer, the plants will be lighter and the old leaves become yellow;fruit trees are small, less fruit, thick peel, hard Skin, hard and hard.

2. Promote the development of crops in the growth period of growth

During the growth stage of crops, Urea on crops can promote the development of crop (especially fruit trees).The use of Urea for crops can promote the nitrogen content of crop blades, speed up the growth of new shoots and inhibit flower buds.

3. Killing pests

Urea is used as leaf Fertilizer, while killing the crop, it can kill pests.After dissolving Urea and laundry powder with water, the crop surface is sprayed on the crop. It can quickly supplement the crop to supplement Fertilizer and effectively kill some pests.The killing performance of software pests such as green insects, aphids, and red spiders has reached more than 90%.As a neutral Fertilizer, Urea is easily absorbed by the leaves, and the damage to the crop is very small.

2. What are the uses of agricultural Urea

In terms of agriculture, Urea is used as a Fertilizer, and there are many uses. The main uses are the following:

1. Fertilization

(1) Urea is a neutral speed -effective nitrogen fertilizer, which can be used as base Fertilizer, topdressing, and leaf surface Fertilizer. The main function is to promote cell division and growth, and promote the leaves of the plant.

(2) If Urea wants to be used for Fertilizer, the seeds and Urea should be kept a certain distance to avoid direct contact.

2. Adjust the amount of flowers

Apple small years, about 5-6 weeks after the apple tree blooms, 0.5%Urea solution is applied to the leaf surface, spraying twice continuously, which can increase the nitrogen content of the leaves, accelerate the growth of new shoots, and inhibit the differentiation of flower bud.

3. Sparse flowers and fruit

Peach trees are more sensitive to Urea. After spraying 8-12%Urea solution, within 7-14 days, sparse flowers can be achieved.

4. Prevention and treatment pests

According to the proportion of Urea: washing powder: clear water = 4: 1: 400, mixes evenly, spray the leaf surface, and can prevent and treat pests such as aphids, red spiders, vegetables and other pests on crops such as fruit trees, vegetables, cotton.

5. Do feed additives

For cows above June, sheeps over March can be added to daily feed.Under normal circumstances, the amount of Urea should not exceed 1%of the dietary and dry substances, and it can also be used by adding 15-20g Urea per 100kg weight.

6. rice species

During the spikes and beginning of the rice, 1.5-2%Urea solution is used to spray the parent or mother, which improves the bisection rate of the parents.

Is the fermented fruit Skin the nitrogen fertilizer?

In fact, after the vast majority of fruit Skin is fermented, it can make nitrogen fertilizer.For example, after the banana peel is fermented, it can be made into nitrogen fertilizer. Both orange peel and apple Skin can be made into nitrogen fertilizer.

How to make fruit Skin production methods

1 You can chop the fruit Skin, and then put it in the sealing of the utensils prepared by everyone. It needs to be poured into the water and placed in the place where the sun can illuminate. 15 arrive 60 God, it can ferment very well.But everyone must pay attention, the utensils must be left 20% The upper and lower parts can prevent the gas from rising under the condition of fermentation, and then the utensils explode.

2 Or prepare a potted Flower pot in advance, put some soil layers in the potted Flower pot, and then spread the peel on the soil layer. In the second floor, a layer of peel should be paved.In addition, in this kind of push, that is so thin 5cm Green plants can be planted in the case of up and down.

What flowers are suitable for fermented fruit Skin

1. Apple Skin

1 As well as Apple fermented water is acidic and can be used to pour acid -like flowers. Most southern flowers are acidic, such as Milan, gardenia, azalea, Clivia, Jasmine, Fairy Classes, Cylinder, Smile flowers, Tong Tong, Golden Flower Tea, Costume, Red Palm, etc.Essence

2 As well as Watering apples of these flowers can not only improve the acid and alkali of the soil, provide a more suitable environment for flowers.

2. Orange peel

1 , Orange Skin water is slightly acidic Fertilizer, suitable for like acidic plants, such as rhododendrons, laughing, Bailan, jasmine, gardenia, osmanthus, bacheme, ivory red and so on.

2 , Orange Skin is rich in vitamins and sperm oil. Under the dissolution of water, the nutrients in it will be acidic in the soil, which can well change the acid and alkali of the soil.If it becomes fade, it will provide the nutrients required for the root system, which is more beneficial to the growth of flowers.
