Water-saving irrigation method of integrated water and fertilizer for fruit trees in northern mountainous areas

Abstract

The invention discloses a northern mountainous area fruit tree water and fertilizer integrated water-saving irrigation method which includes the steps: first, collecting rainwater in rainy seasons; second, monitoring water and fertilizers and detecting the water and fertilizers in soil at the position of each fruit tree through a chemical sensor and a soil humidity sensor by an electric control device; third, preparing for drop irrigation; fourth, performing drop irrigation, and continuously running the first step and the second step after stopping drop irrigation. Water with the highest evaporation velocity in an auxiliary water storage tank is conveniently and preferentially used for drop irrigation, water and fertilizer use ratio is high, fruit tree root systems are uniformly watered, the fertilizers are conveniently added into the water, and water and fertilizer overflow of a fertilizer conveying pipe is prevented. Drop irrigation effects are improved, moisture conservation functions are good, the fertilizers and labor are saved, weeds among fruit tree plants do not easily grow, a mobile phone can be used for automatic remote control, water pump gravity irrigation is omitted, fruit tree growth is promoted, yield is improved, water and soil loss and environmental pollution caused by the fertilizers are reduced, ecological benefits are obvious, and energy is saved.

Description

technical field [0001] The invention relates to the technical fields of agriculture and water conservancy, in particular to a method for watering fruit trees in mountainous areas. Background technique [0002] The arid mountainous areas in northern my country lack water resources, poor agricultural production conditions, less rainfall, uneven temporal and spatial distribution of rainfall, and concentrated rainfall periods. 75%-85% of annual precipitation is concentrated in June-September, and spring droughts and droughts often occur. Autumn drought phenomenon. Moreover, the mountainous terrain changes greatly and the terrain is complex, which is not conducive to the construction of long-distance pumping station water delivery projects. [0003] It is difficult to develop groundwater resources in mountainous areas. The depth of wells in most areas is 100-200 meters, and some reach 300-400 meters. It is difficult and expensive to drill wells in arid mountainous areas. When enc...

Moreover, the mountainous terrain changes greatly and the terrain is complex, which is not conducive to the construction of long-distance pumping station water delivery projects

[0003] It is difficult to develop groundwater resources in mountainous areas. The depth of wells in most areas is 100-200 meters, and some reach 300-400 meters. It is difficult and expensive to drill wells in arid mountainous areas. When the geological conditions of rock formations are met, the cost of drilling wells is more than 1 million yuan, which is high.

In addition, the traditional irrigation method is ground flood irrigation, which seriously wastes water resources and increases the contradiction between supply and demand of water resources.

In the irrigation method of ground flooding, the fertilizer contained in the water is wasted along with the waste of water resources, which increases the cost
