Micro-irrigation system using Yellow River water and other sediment water and plant water-saving cultivation method

Abstract

The invention discloses a micro-irrigation system using Yellow River water and other sediment water and a plant water-saving cultivation method. The micro-irrigation system diverts sediment water from a water source to a plantation to perform micro-irrigation on plants. The micro-irrigation system comprises micro-irrigation hoses which are PE plastic pipes provided with a plurality of overflow micropores along the length directions of the micro irrigation hoses. The micro irrigation hoses are arranged on the ground of the plantation, one ends of the micro irrigation hoses are connected to the water source, and the other ends are sealed. Water from the water source flows in the micro irrigation hoses and overflows from the overflow micropores of the micro irrigation hoses to irrigate the plants. By the aid of the micro irrigation system, the sediment water is free of filtering and precipitation, existing water channels are free of changing, power consumption and pressure applying are omitted, and Yellow River water and other sediment water can be sprayed to roots of the plants for micro irrigation can be implemented by own water pressure of the water channels. In addition, the micro irrigation technology can be combined with the plant root-controlled cultivation technology, and water waste of soil leakage is further reduced.

Description

technical field [0001] The invention relates to the field of water saving, in particular to water saving irrigation. Background technique [0002] As early as 1988, the document of the World Commission on Environment and Development pointed out: "Water resources are replacing oil as the main problem causing crises all over the world". The lack of water resources has become a common concern of today's human society. my country's per capita water resources are 2200m 3 , which is less than 1 / 4 of the world's average level, is a country seriously short of water resources, and with the rapid increase of population and the development of industry, the gap will become larger and larger in the future. [0003] In the Ningxia Plain in western my country, southern Xinjiang, the Hexi Corridor in Gansu, and the Hetao area in Inner Mongolia, precipitation is scarce (15-300mm) and evaporation is huge (above 3000mm), and agricultural production is completely dependent on Yellow River wat...

Problems solved by technology

However, drip irrigation requires clean water, and the Yellow River water containing sediment will block the drippers and drippers, making it difficult to implement

Even if clean water sources such as well water are used, drip irrigation still requires complicated equipment such as filtration and pressurization, and the price of drip irrigation pipes is also high, with high one-time investment and high equipment maintenance costs

Moreover, drip irrigation must be pressurized, consumes electricity, and has high operating costs.
