Method for water and fertilizer integrated automatic fertigation for sugarcane

Abstract

Provided is a method for water and fertilizer integrated automatic fertigation for sugarcane. The method comprises the steps that a water and nutrient solution mixing storage tank is rationally set and established in a sugarcane planting area, and nutrients required for the sugarcane at each growth stage are first mixed well in the storage tank and then supplied to sugarcane plants to be absorbed; a fertigation pipeline and a drip irrigation pipeline are laid in a sugarcane planting area, the fertigation pipeline is connected with a water pump, the water pump is started during the fertigation of water and nutrient solution, and the water and the nutrient solution are sprayed out through dripping holes formed in the fertigation pipeline and the drip irrigation pipeline to be absorbed by the sugarcane plants planted beside the dripping holes; the water pump is controlled through a microcomputer time controller, and accordingly the automatic fertigation of the water and the nutrient solution during the sugarcane cultivation is achieved. The method has the obvious advantages that the method is small in investment and low in cost, saves labor and fertilizer and is easy to operate and the sugarcane is high in yield and quality.

Description

technical field [0001] The invention belongs to the technical field of facility agriculture, and in particular relates to a method for automatic irrigation of sugarcane with water and fertilizer integration. technical background [0002] Sugarcane is an economic crop with a long growth period and a large demand for water and fertilizer. Traditional field irrigation and fertilization methods not only have low water and fertilizer use efficiency, but also require a large amount of labor for field fertilization and irrigation. In recent years, with the development of light and simple agricultural water-saving facilities and materials, a new water-saving technology, sugarcane drip irrigation technology, has been developed in sugarcane production management. gratifying sight, unaffected by drought. Its working principle is to pump water up, pass through filters and fertilization pools, and then transport "rain and dew" to the roots of each sugarcane through nearly a hundred bra...
