Planting method for increasing corn yield

Abstract

The invention discloses a planting method for increasing a corn yield. The planting method is characterized in that base fertilizers applied when seeds are sown are compound biological bacterial fertilizers comprising inorganic compound fertilizers and organic biological bacterial fertilizers which are mixed with one another. The planting method has the advantages that the biological bacterial fertilizers in the applied base fertilizers can continuously release nutrients after being decomposed, so that the photosynthesis of crops can be promoted, a nutrient element utilization rate can be increased, a yield increasing effect is obvious, the planting method is wide in applicability and is non-toxic and harmless, the stress tolerance of the crops can be improved, and environmental pollution can be prevented; soil can be activated by the applied base fertilizers, the structure of the soil can be improved, the water storage and fertilizer conservation ability and the permeability of the soil can be enhanced, the soil fertility is developed and can be durable, and nutrients can be timely supplemented to the soil by the inorganic fertilizers in the base fertilizers.

Description

technical field [0001] The invention relates to a cultivation method of crops, in particular to a cultivation method for increasing corn yield. Background technique [0002] Corn, also known as maize, corn, corn, and cob, is an annual herbaceous plant in the family Gramineae, belonging to the genus Zea in the Poaceae Zea family. It is the largest food crop in China, and its main production area is located in the third largest corn belt in the world - Songliao, China. Plains Corn Belt. The total planting area of ​​corn is about 1249.35 square kilometers. It is an important food crop and an important source of feed, and it is also the food crop with the highest total output in the world. Corn is a staple food material. It is known as a longevity food. It has the effects of weight loss and longevity. It is the category with the highest nutritional value. Its vitamin content is 5-10 times that of rice and wheat. The high-quality cellulose can not only stimulate intestinal peri...

Problems solved by technology

In addition, due to the widest distribution and largest area of ​​corn planting, the physical and chemical properties of the soil are relatively diverse. In addition, the structure of the soil is destroyed due to the perennial planting, and the fertility of the soil alone cannot meet the nutritional needs of the crops. However, the existing application All fertilizers are single compound fertilizers

Inorganic compound fertilizer or organic biological bacterial fertilizer. Inorganic compound fertilizer refers to an inorganic fertilizer made only by chemical methods containing at least two nutrients among nitrogen, phosphorus, and potassium. Organic biological bacterial fertilizer is based on microorganisms. The life activities of the crops cause the crops to obtain a specific fertilizer effect; long-term excessive application of a single type of chemical fertilizer will cause soil compaction, soil acid-base imbalance, crop yield reduction, quality decline, and slow absorption speed, affected by soil physical and chemical properties and temperature, etc. Factors have a high degree of influence, and the effect of increasing production is not significant
