Description

A fertilization device for returning corn stalks to the field

technical field

The utility model relates to the technical field of agricultural machinery devices, in particular to a fertilization device for returning corn stalks to the field.

Background technique

Straw returning is a method of returning corn stalks to the field to apply straws (corn stalks, sorghum stalks, etc.) that are not suitable for direct feed into the soil directly or piled up and decomposed. It can improve soil properties, accelerate soil ripening, and improve soil fertility. When directly plowing the straw, some nitrogen fertilizer should be applied to promote the straw to decompose in the soil and avoid competition between decomposing bacteria and crops for nitrogen.

Straw returning to the field has the advantages of promoting the increase of soil organic matter and nitrogen, phosphorus, potassium and other contents; improving the storage capacity of soil moisture; improving plant properties and crop yield; improving soil properties and increasing aggregate structure. Straw returning to the field has a significant effect on increasing fertilizer and production, and generally can increase production by 5% to 10%, but it is not easy to achieve such an effect. Therefore, only by taking reasonable measures of straw returning to the field can a good effect of returning to the field be achieved.

However, the stalks crushed by the existing device are relatively large, of different lengths, and rot slowly, and cannot be absorbed and utilized by the soil quickly. At the same time, the existing crushing device does not crush the rhizome of corn, which affects the crops to a certain extent. The production of diseased straw will cause the spread of the disease after being mashed and returned to the field, and harmful substances such as insect eggs attached to the straw will also cause harm to the sown crops, causing environmental pollution and property loss.
