Problems solved by technology

However, in most of the rain-fed agricultural areas in northern my country, affected by the drought, the phenomenon of incomplete seedling emergence, incomplete seedling emergence, and lack of seedlings and broken ridges usually occurs due to poor soil moisture in the plow layer after corn sowing, which seriously affects the establishment of high-yield corn populations and yield formation. , Some plots that cannot be planted in water, due to long-term drought after sowing, the seeds lose water and have no vitality, resulting in powder seeds, resulting in common phenomena of farmers replenishing seedlings and destroying seeds. In the process, too much emphasis is placed on

Abstract

The invention discloses drought-resistant full-nutritional long-acting fertilizer dedicated for corn and a preparation method thereof and belongs to the field of dedicated fertilizers for agricultural crops. The drought-resistant full-nutritional long-acting fertilizer dedicated for corn is made mainly from, by weight, 410-510 parts of urea, 0-250 parts of ammonium sulfate, 150-275 parts of monoammonium phosphate, 100-200 parts of potassium chloride, 5-30 parts of zinc sulfate, 10-50 parts of fulvic acid, 2-15 parts of a polymer water-holding agent, 1-5 parts of a nitrification inhibitor, and 2-10 parts of a fertilizer synergist. The influence of drought on corn planting is decreased, corn emergence rate is increased, rooting is promoted, corn drought resistance is improved, the fertilizer can fix nitrogen and activate phosphorus, nutrition release period is prolonged, zero-topdressing production of corn is achieved, and stable yield, labor saving and synergy are achieved. The drought-resistant full-nutritional long-acting fertilizer dedicated for corn is used mainly as disposable base fertilizer for corn.

Description

technical field [0001] The invention belongs to the field of special fertilizers for agricultural crops, and in particular relates to a special long-acting fertilizer for drought-resistant and full-nutrition corn and a preparation method thereof. Background technique [0002] Corn is the largest food crop in my country and an important source of food and feed. According to the statistics of the National Bureau of Statistics, in 2015 my country's corn planting area reached 381.166 million hectares, with a total output of 224.58 million tons. As the main corn-growing areas in Northeast China and North China, corn planting is the main source of farmers' income. It is of great significance to ensure stable corn production, reduce land investment, and increase farmers' income. However, in most of the rain-fed agricultural areas in northern my country, affected by the drought, the phenomenon of incomplete seedling emergence, incomplete seedling emergence, and lack of seedlings and...
