Abstract

The invention discloses a water and fertilizer integrated special fertilizer for corn and an application method thereof. The corn special fertilizer comprises seedling emergence special fertilizer, ear period special fertilizer, and flowering period special fertilizer; and the three special fertilizers all comprises the following components: urea, diammonium phosphate, potassium chloride, chelated zinc, boric acid, chelated manganese, chelated magnesium, chelated iron, and chelated copper. The fertilizer is developed on the basis of rules of corn nutrient needs, different fertilizer formulas are adopted in different growth periods, and thus the pertinence is strong. Moreover, the ratio of nitrogen to phosphate to potassium is reasonable, the massive nutrient requirements in different growth period of corn can be met by the fertilizer, at the same time, trace elements are added to balance the nutrients in the fertilizer, the fertilizer utilization rate becomes higher, the corn yield is prominently improved, and the goal of increasing output is achieved. All the nutrients in the fertilizer are quick-acting nutrients, the water solubility of the fertilizer is good, and the fertilizer property is stable, so the fertilizer will not obstruct the nozzle during the drop irrigation process when the fertilizer is used in drop irrigation, the fertilizer and water are saved, and thus the fertilizer is suitable for promotion and application.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, in particular to a special fertilizer for the integration of water and fertilizer for corn, and also relates to a method for applying the special fertilizer for the integration of water and fertilizer for corn. Background technique [0002] my country is a country with a large population and a large agricultural country with shortage of water resources, uneven distribution of water resources in time and space, large consumption of chemical fertilizers, and low utilization rate of agricultural water and fertilizer resources. Under the condition of limited resources, it is of great significance to the agricultural development of our country to make full use of the effect of water and fertilizer to increase the grain yield. Corn is an important food, feed and industrial raw material crop in my country, and plays an important role in ensuring national food security. However, the imp...
