Abstract

The invention discloses a special fertilizer for the integration of water and fertilizer for corn and an application method thereof. The special fertilizer for the integration of water and fertilizer includes a special fertilizer for emergence, a special fertilizer for the ear stage, and a special fertilizer for the flowering and grain stage; the three special fertilizers all include the following components: Urea, diammonium phosphate, potassium chloride, zinc chelate, boric acid, manganese chelate, magnesium chelate, iron chelate, copper chelate. The special fertilizer for the integration of water and fertilizer for corn of the present invention is developed according to the demand law of corn for nutrients, adopts different fertilizer formulas in different growth stages of corn, and has strong pertinence; the ratio of nitrogen, phosphorus and potassium is reasonable, and meets the requirement of large amounts of nutrients in different growth and development stages of corn. At the same time, adding trace elements can play a role in balanced fertilization, higher fertilizer utilization efficiency, and can significantly increase corn yields to achieve the purpose of increasing production and income; all nutrients are quick-acting nutrients, good water solubility, stable properties, and drip irrigation Combined with the method, the dripper will not be blocked during the drip irrigation process, has the advantages of saving fertilizer and water, and is suitable for popularization 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...
