PURPOSE

● Regulating the amount of flowers

In order to overcome the big and small year of Apple Field, in the small year, 0.5% urea water solution was sprayed on the leaves of apple tree 5-6 weeks after flowering (the critical period of flower bud differentiation, the growth of new shoots was slow or stopped, the nitrogen content of leaves was decreasing) , and sprayed twice continuously, it can increase the nitrogen content of leaves, accelerate the growth of new shoots and inhibit the differentiation of flower buds, and make the annual flower amount suitable.

● Thinning flowers and fruits

The flower organs of peach trees are sensitive to urea, but the reaction of Gamian is slow. Therefore, the experiments of flower thinning and fruit thinning of peach and nectarine with urea abroad have been carried out, it needs high concentration (7.4%) to show good effect, the most suitable concentration is 8%-12% , within 1-2 weeks after spraying, it can reach the goal of thinning flowers and fruits. However, in different land conditions, in different periods and different varieties of response still need further testing.

● Rice seed production

In hybrid rice seed production technology, in order to increase the outcrossing rate of parents and increase the seed production of hybrid rice or the number of sterile lines, the female parent is usually sprayed with red toxin in order to reduce the neck of the female parent or make it completely withdrawn, or the parent parent is sprayed, adjust the growth of both, make its Florescence synchronism. Because the Gibberellin price is more expensive, uses its to manufacture the seed cost to be high. The experiments were carried out with urea instead of Gibberellin. 1.5%-2% urea was used at booting stage and heading stage (20%) . The effect of reproduction was similar to Gibberellin, and the plant height was not increased.

Pest control

By mixing urea, washing powder and water 4:1:400 parts, it can prevent aphids, red spiders and Pieris rapae on fruit trees, vegetables and cotton.

Urea iron fertilizer

Urea forms iron chelate with FE 2 + in the form of complex. The organic iron fertilizer has low cost and good effect in preventing and curing iron deficiency and losing green. In addition, 0.3% urea with 0.3% iron(2+) sulfate (anhydrous) spray was better than 0.3% iron(2+) sulfate (anhydrous) spray alone.
