Urea fertilizer benefits
Wholesale urea fertilizer is a high-concentration nitrogen fertilizer, a neutral quick-acting fertilizer, and can also be used to produce a variety of compound fertilizers. no harmful substances remain in the soil, and long-term application has no adverse effects. animal husbandry can be used as feed for ruminants. However, if the temperature is too high in granulation, a small amount of biuret, also known as biuret, will be produced, which has an inhibitory effect on crops.
Urea fertilizer is an organic nitrogen fertilizer, which can be absorbed and utilized by crops after being hydrolyzed into ammonium carbonate or ammonium bicarbonate by the action of urease in the soil.therefore, urea should be applied 4 to 8 days before the fertilizer-requiring period of crops.
Urea fertilizer uses
Adjust the amount of flowers
In order to overcome the age of apples, in the case of small years, 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 shows a downward trend) foliar spray with 0.5% urea aqueous solution , Continuous spraying 2 times can increase the nitrogen content of the 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.
Flower thinning and fruit thinning
The flower organ of peach tree is more sensitive to urea, but the reaction of the surface is relatively slow. Therefore, foreign urea has been used on peaches and nectarines to conduct flower thinning and fruit thinning experiments. (7.4%) can show good effect, the most suitable concentration is 8%-12%, within 1-2 weeks after spraying, the purpose of thinning flowers and fruits can be achieved. However, under different land conditions, the response of different periods and different varieties needs further experiments.
Rice seed production
In the hybrid rice seed production technology, in order to increase the outcrossing rate of the parental parent, to increase the amount of hybrid rice seed production or the breeding volume of sterile lines, gitoxin is generally used to spray the female parent to reduce the degree of cervical encroachment of the female parent or to make It can be completely extracted; or spray the parent parent to adjust the growth of the two to synchronize the flowering period. Because gibberellin is more expensive, the cost of seed production is high. People use urea instead of gibberellin for experiments, and use 1.5%-2% urea at the peak booting stage and the beginning of the ear (20% heading), the breeding effect is similar to that of gibberellin, and the plant height will not increase.
Pest control
Using urea, washing powder, and water in 4:1:400 parts, after stirring and mixing, can prevent pests such as aphids, red spiders, cabbage worms on fruit trees, vegetables, and cotton, and the insecticidal effect is more than 90%.
Urea iron fertilizer
Urea forms chelated iron with Fe2+ in the form of a complex.this organic iron fertilizer is low in cost and has a good effect on preventing iron deficiency and chlorosis. In addition, 0.3% urea was added when 0.3% ferrous sulfate was sprayed on the foliage, and the effect of preventing chlorosis was better than that of single spraying 0.3% ferrous sulfate.
