Water-saving and efficient cultivation method for drip irrigation of potatoes in cold region

Abstract

The invention relates to a water-saving and efficient cultivation method for drip irrigation of potatoes in a cold region. The potato efficient cultivation method is mainly disclosed according to soilof the cold region and climatic characteristics. A large-ridge double-row and one-pipe double-row drip irrigation cultivation mode serves as the basis, and planting density increase and land utilization rate increase serve as targets. The problems that the soil in the cold region is compact and a traditional drip irrigation mode is small in tuberization are considered, and matched cultivation andridging agricultural measures and a matched cultivator are disclosed; through cultivation and ridging, a drip irrigation belt is shallowly buried, and a shallow-buried underground drip irrigation system is constructed; meanwhile, the problems that a surface drip irrigation belt is likely to move due to the influence of wind in the early stage of planting and weeds are likely to grow are solved. Adrip irrigation system is internally provided with a fertilization and air addition device, a central controller, a soil moisture collector, a valve controller and other wireless automatic control equipment, and automatic precise control over water, fertilizer and air amount in all growth stages of potatoes can be conducted. Automatic control over potato planting is achieved, and production efficiency is improved.

Description

technical field [0001] The invention relates to a high-efficiency drip irrigation and water-saving cultivation method for potatoes in cold regions, in particular to a drip irrigation potato cultivation method combined with automatic control, intertillage covering soil and integrated regulation of water, fertilizer and gas. Background technique [0002] Potato is one of the fourth largest food crops in my country. At present, the potato planting area in my country is more than 5 million hectares, mainly distributed in the southwest, northeast, northwest and other regions, and the area and output account for about 1 / 4 of the world. According to relevant information According to statistics, my country has become the largest potato production and consumption country. Cultivated land in cold regions in my country is the main area for potato planting, and its potato planting area is stable at 420,000 hectares all year round. Seasonal drought and severe shortage of water, soil and ...

AI Technical Summary

Problems solved by technology

Considering the relatively dense soil in cold regions and the small space for tubers in the traditional drip irrigation mode, agronomic measures for cultivating soil and supporting cultivating machines were proposed. Through cultivating and cultivating soil, the drip irrigation belt was shallowly buried to construct a shallow underground drip irrigation system. Solve the problems that the surface drip irrigation belt is easily affected by wind, displacement and weeds in the early stage of planting

[0005] (1) Comprehensively using automatic control technology and crop root zone water, fertilizer and gas regulation technology, combined with intertillage and soil-covering agricultural machinery and agronomic measures, a method of drip irrigation, water-saving and efficient cultivation of potatoes in cold regions was constructed, which solved the poor adaptability of current drip irrigation technology in cold regions problems, providing a solution for the water-saving and efficient cultivation of potatoes in cold regions
