Dry and thin wheat fields are often unable to be topdressed due to the inability to water, and the wheat field consumes some nutrients during the winter wheat field, which often leads to the inhibition of growth in the middle and late stages of wheat due to malnutrition, resulting in small ear, small grain and low grain weight. Therefore, we should skillfully use the local natural conditions and timely fill the fertilizer to achieve the purpose of increasing wheat yield. The specific method of its topdressing skills is:
Borrowing with snow. When the winter snow falls below 10 cm, a non-volatile, fast-dissolving nitrogen fertilizer can be used. Such as urea, the amount of 7.5 kg to 10 kg per mu, spread evenly on the snow, so that it melts into the ground together with the snow.
Top Ling topdressing. When the early spring has not completely thawed, it will return to the slurry after application. At this time, the upper layer soil can be fertilized by slurry because of the high humidity. Fertilization should be carried out at about 2 pm, deep application (mixing of nitrogen and phosphorus fertilizers is good), and the application is tight.
Fertilize by the rain. In the case of rain or heavy rain as follows, it can be applied with the rain, or it can be applied after the rain.
Foliar application. If there is no snow and no rain, it can be sprayed on the foliar surface. Spray fertilizer can not only increase the nutrition of wheat but also improve the drought resistance of wheat. Mu 2% urea solution or 0.3% potassium dihydrogen phosphate solution 50 kg ~ 75 kg, the two can also be mixed spray. Spray 2 times to 3 times in the up, boot, and filling stages of wheat. It can also be applied in combination with an agent for controlling pests and diseases of wheat, and such an operation can achieve a multiplier effect.
