Irrigation device suitable for apple cultivation in arid area in northwest

Abstract

The invention discloses an irrigation device suitable for apple cultivation in an arid area in the northwest. The device comprises a combined shell, the combined shell is provided with a slanting insertion hole, an inclined cavity type water storage device is inserted into the slanting insertion hole, the inclined cavity type water storage device is internally provided with a polymethyl methacrylate block absorbing enough water, the inclined cavity type water storage device is internally provided with pesticide powder, the pesticide powder is placed in a filter net, the combined shell is connected with the inclined cavity type water storage device through a clamping connecting device, the inclined cavity type water storage device is connected with a circular sleeve, the bottom of the circular sleeve is provided with an insertion opening, the circular sleeve is tightly cooperatively in clamped connection with a circular shaft, the circular shaft is connected with a supporting leg, and the supporting leg passes through the insertion opening. The irrigation device suitable for the apple cultivation in the arid area in the northwest has the advantages that the polymethyl methacrylate block absorbing enough water and the pesticide powder are arranged in the inclined cavity type water storage device, so that the requirement of the irrigation water quantity required for newly plantedseedlings is met, and the effect of pesticide applying irrigation is achieved, thereby improving the survival rate of the newly planted seedlings, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to an irrigation device suitable for apple cultivation in the arid area of ​​Northwest China. Background technique [0002] The Longdong apple production area in Gansu Province is rich in light and heat resources, has a high altitude, and a large temperature difference between day and night. It is one of the main apple production areas with advantages. The rainfall in this area is insufficient, about 500-550mm, concentrated from July to September. In addition, the groundwater level is deep, the surface is bare, and the water evapotranspiration is large, so the water regulation effect of deep soil is greatly reduced. It belongs to the typical rain-fed agricultural area of ​​the Northwest Loess Plateau. The life cycle of apples consumes a lot of water, but the orchards in this area are still mainly managed by the clear tillage system. The deterioration of the rhizosphe...

AI Technical Summary

Problems solved by technology

[0003] At present, water-saving planting of fruit trees in arid areas, more promotion of film-mulching cultivation, short-term application of this measure, can slightly increase soil moisture, but in the long run, orchard rhizosphere soil is prone to increase in bulk density, decrease in beneficial microorganisms, surface soil compaction, and slow absorption root growth , affecting the absorption of soil moisture and nutrients by apple trees, which is not conducive to the sustainable and healthy development of apple cultivation
