Fertilization outside the root of corn during grain filling

During the grain filling stage of corn, whether the organic matter stored in the stem is transferred to the grain is the critical period for determining the number of effective panicles, the number of grains per panicle and the grain type. On the basis of attaching importance to the application of attacking and licking fertilizers, taking the method of root dressing in the filling stage, spraying 1-2 times, will receive twice the result with half the effort. The specific application methods are as follows:

1. 1 kg of urea, 100 g of potassium dihydrogen phosphate, and 60-72 kg of water.

2, using 1 kg of urea, 100 g of potassium dihydrogen phosphate, 100 g of borax to form an aqueous solution, and then spray 60-75 kg of water.

3, 1.5 kg of urea, 100 g of potassium dihydrogen phosphate, 150 g of zinc sulfate, mixed with water 60-75 kg spray.

The above formula, any one, with the use. It is better to spray it before 10 am or after 4 pm on sunny days. If there is heavy rain after spraying, it should be sprayed once after the weather turns fine. Do not spray at high temperatures at noon.
