Description

A kind of agricultural irrigation irrigation system based on deep soil layer irrigation technology
Technical field
The present invention relates to agricultural irrigation technology, specially a kind of agricultural irrigation based on deep soil layer irrigation technology fills Irrigate system.
Background technology
It irrigates, for the technical measures of moisture needed for ground supplement crop.In order to ensure crop normal growth, it is steady to obtain high yield Production, it is necessary to supply crop with sufficient moisture.Under field conditions (factors), often uneven because of precipitation deficit or distribution, it cannot Meet crop to moisture requirement.Therefore, it is necessary to artificially be irrigated, to mend the deficiency of natural rainfall.It irrigates, i.e., is poured with water Ground.Irrigation principle is that irrigation volume, irrigation frequency and time will be according to medicinal plant water-requiring property, growing stage, weather, soil items , in due course, in right amount depending on part, Rational Irrigation.Its type mainly have irrigation before seeding, urge seedling to pour water, growth period pours water and winter It pours water.
Since the founding of People's Republic of China, extensive and long-term irrigation and drainage Capital construction of project is carried out, act is achieved The great achievement that generation is attracted attention provides irreplaceable infrastructure and substance for the sustainable development of China's agricultural and national economy Ensure.To the end of the year 2003, national irrigated area reaches 55,800,000 hectares, and 40% arable land is made to have irrigating facility.It 1949, fills Water consumption is irrigate less than 1000 billion cubic meters, accounts for about the 16.3% of cultivated area at that time.0.03 hectare of per capita irrigated area (0.44 mu).By 2003, reach 3300 billion cubic meters.Although China's Development achieves prodigious achievement, also face Serious challenge, shortage of water resources has become the main restricting factor of Chinese society's sustainable economic development.2002, entirely State's total water consumption is 5497 billion cubic meters, accounts for the 19.5% of current year gross amount of water resources, wherein urban domestic water accounts for 5.8%, rural area Domestic water accounts for 5.4%, and industrial water accounts for 20.8%, and farmland irrigation water accounts for 61.4%, Lin Muyu and accounts for 6.65 with water.Although from now on Total supply can increased, but with industry and the development of urbanization and the raising of living standards of the people, more and more Water is used to meet the needs of industry and resident living, and irrigation water will be more nervous, and agricultural irrigation water shortage is every year up to more than 300 hundred million Cubic meter, but agricultural water waste is serious, and national irrigation water using efficiency only has 40% or so.In the 1970s, national farmland by About 11,000,000 hectares every year on average of non-irrigated area then reaches about 20,000,000 hectares and 2700 every year on average respectively to the eighties and the nineties Ten thousand hectares.In addition, effective control is not yet received in China's water resource pollution.According to water quality assessments in 2002 as a result, being commented in investigation In 12.3 ten thousand kilometers of rivers length of valence, four class water rivers length accounts for 12.2%, and five classes or bad five classes water river length still account for 23.1%.
Field irrigation is to ensure the conventional means of moisture needed for field-crop normal growth, at present when field irrigation, generally By the way of building flume or using water pump, flume, which is built, to be needed, with geographical advantage, ideally to need river Horizontal plane is higher than farmland horizontal plane, and flume is easy to block, and needs frequent troubleshooting, applies limit to very much in this way. When the water in river being pumped into farmland using water pump, pipeline is pumped using bright pipe or by the way of being embedded in underground, underground is embedded in and is not easy The case where determining pipeline location, piping failure is be easy to cause when ploughing bottom occurs, and there is also corrosion when pipeline normal use Breakage, damage location are not easy to determine, repair tired;And existing irrigation method is more single, some uses low latitude trickle irrigation, directly The watering of row root is tapped into, but the cauline leaf of crop can not be carried out directly to spray moisturizing, " washing " of rainwater type is realized to crop, Have plenty of and poured using sprinkling, this spray pattern acts directly on the cauline leaf of crop, and root moisturizing is insufficient so that irrigates effect Fruit is greatly reduced.
