Stubble cane pre-emergence fertilizing machine and application thereof

Abstract

The invention belongs to the field of agricultural fertilizing equipment, and particularly provides a stubble cane pre-emergence fertilizing machine and application thereof. The stubble cane pre-emergence fertilizing machine comprises a rack, a round disc knife, a transverse cutting device and a fertilizing device are arranged below the rack in sequence, and the transverse cutting device comprisesa longitudinal cutting board and transverse cutting knives arranged at the two sides of the longitudinal cutting board; the round disc knife is driven by a driving device to backwards rotate. On thepremise of sugarcane leaf land returning, the purpose of disposable ridge breaking, bag loosening and fertilizing can be achieved, and the field work efficiency is improved. Stubble cane post-emergence fertilizing is changed into pre-emergence fertilizing, sugarcane seedlings cannot be injured, soil beside sugarcane bags can be cut and loosened by the transverse cutting knives, air ventilation isfacilitated, and the seedling emergence rate is increased. Fertilizer is deep applied in advance, soil covers the fertilizer, nutrients are spread into soil, uniform absorption of root systems of sugarcanes is facilitated, sugarcane leaves cover the ground surface, water evaporation can be reduced, more rainwater can also be permeate the soil, and water and soil loss is reduced.

Description

technical field [0001] The invention belongs to the field of agricultural fertilization equipment, and specifically provides a perennial cane pre-emergent fertilization machine and its application. Background technique [0002] After the sugarcane was harvested in the previous year, the buds of the cane stalks left in the sugarcane soil germinated and unearthed under suitable environmental conditions (mainly temperature and humidity), and then grew into cane plants, which are called perennial root cane. Traditional ratoon cane management is characterized by burning sugarcane leaves and post-emergence fertilization, including: burning sugarcane leaves after harvesting the sugarcane, then plowing both sides of the cane with oxen, breaking the ridges to loosen the bushes, and fertilizing after the emergence of the ratoon cane. This method has the following disadvantages: three processes of burning sugarcane leaves, breaking ridges, fertilizing and cultivating soil are required,...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: three processes of burning sugarcane leaves, breaking ridges, fertilizing and cultivating soil are required, and the sugarcane leaves must be burned first, which cannot achieve the effect of returning straw to the field and causes air pollution

If only the disc knife is used to loosen the soil, the soil clods on both sides of the disc knife are often larger. After the disc knife cuts, the soil on both sides is difficult to return to the soil, and the exposed fertilizer will affect the effect of fertilization.
