A kind of method of fixedly ridge culture, underground drip irrigation cultivation
Technical field
The present invention relates to a kind of method of fixedly ridge culture, underground drip irrigation cultivation, say more specifically a kind of applicable large tracts of land Dry Farmland ridge planting technology, belong to the technical field of agricultural cultivation.
Background technology
Agricultural production is the source of the mankind's basic necessities of life, and existence originally.Throughout history, primitive farming, traditional farming and modern agriculture three phases have successively been experienced in agricultural production.Since modern age, extensive use oil power machinery in agricultural production, a large amount of outside chemical product such as chemical fertilizer, agricultural chemicals that use, add the irrigation and water conservancy progress of perfect, improvement of crop cultivar and culture technique gradually, agricultural productivity improves greatly, grain yield increases considerably, solved to a certain extent the demand that food quantity increases and nutrition improves of bringing because of the population growth, but along with expanding economy, increasing people leaves rural area and migrates city, agriculture arable area is also in continuous minimizing simultaneously, and agricultural is faced with new problem and challenge.With regard to northern China dry land cultivation area, having at present following problem (take Wheat Maize Rotation) is example:
1) be to pursue high yield in agricultural production, drop into a large amount of fertilizer, cause utilization rate of fertilizer low, cause the wasting of resources, and be with environmental pollution.Its reason be mainly the producer in order to save time, reduced fertilizer application frequency, improved fertilizer amount.Be generally that fertilizer spreads fertilizer over the fields or brings into as base fertilizer during mechanical planting when ploughing, due to inconvenient mechanically actuated during plant growth, be difficult to realize ditching-fertilizing, earthing operation, general artificial spreading fertilizer over the fields in earth's surface, impose number of times in the majority with 1 time.
2) water scarcity is obvious gradually on the impact of agricultural production.Current normal nearly 400 billion cubic meters of time water deficit in the whole nation, about 300 billion cubic meters of agriculture lack of water wherein, not only the water yield lacks, and the water pollution situation also is on the rise.Because agricultural is the water rich and influential family, its water consumption accounts for 70% of national water total amount, wherein 90% for plant husbandry, irrigate, but the water waste situation is very serious on agricultural, and national irrigation water availability only has 40% left and right.Along with industry and the development of urbanization and the raising of living standards of the people, increasing water is used to meet the needs of industry and resident living, and irrigation water will be more nervous, and in recent years, national area suffered from drought reaches more than 3,300 ten thousand hectares every year on average.
3) agricultural machinery is universal gradually when crop is cultivated and gather in the crops, but track is fixing while using, and has formed gradually tillage pan, and the formation of tillage pan can affect crop to moisture, nutrien utilization.And, when ploughing every year, due to fixing track not, on the soil that can only travel after ploughing, plough rear soil soft, and while making agricultural machinery travel, resistance is large, and oil consumption is high.On the other hand, due to fixing track not, agricultural mechanical operation is application when plantation and results just, and during plant growth, field management can't be applied easily.
For improving the availability of moisture and fertilizer, water-fertilizer integral becomes important development direction of current agricultural production.This technology is an agrotechnique of water and fertile synchronous supply, the solution that soluble solids or liquid fertilizer are mixed with, by pressure system, together with water, irrigate, evenly, regularly, quantitatively infiltrate crop root development growth zone according to regulation of fertilizer requirement and the characteristics of soil nutrient content and crop species, moisture, nutrient regularly, directly offer crop quantitatively, in proportion, meeting the crop different growing stages needs water, needs fertilizer, thereby reaches the purpose that improves crop quality, increasing both production and income.Drip irrigation is the principal mode of the Integration of Water into Fertilizer, and the position according to hollow billet in drip irrigation project in field is divided on the ground and underground two kinds of situations:
1) hollow billet is arranged in to ground, between Irrigation Period, the not mobile system of hollow billet and irrigator is called the fixed system in ground.These type systematics of the most employing of drip irrigation now.Its advantage is installation, easy to maintenance, the situation of also being convenient to check ground moistening and measuring the water dropper changes in flow rate; Shortcoming is that hollow billet and irrigator are easy to damage and aging, also influential to the field farming.
2) hollow billet and the whole buried systems of irrigator (being mainly water dropper) are called to underground fixed system.This is the updating and improve of drip irrigation technique in recent years, and irrigator just occurs after stopping up and reducing, and the application area enlarges gradually.With the fixed system in ground, compare, its advantage has reduced evaporation from topsoil and salt accumulation, has exempted the work of hollow billet installation and removal before and after crop-planting and results and the failure loss of equipment, has extended the service life of equipment; And there is no pipeline on earth's surface, do not affect the simple and easy farming operation in field, but, in the middle of actual use procedure, it is installed, and process of deployment is comparatively complicated, the water dropper of described embedded underground easily stops up, once damage, its replacement and maintenance cost is larger.
Underground drip irrigation is generally acknowledged it is one of the most rising efficient water-saving irrigation technology by common people, but still is restricted in the large Tanaka's of Farming application, and wherein being embedded in underground pipeline, can to affect the machinery operation of turning over be a more crucial factor.So be generally that pipeline is embedded into below plow layer in prior art, it is 40cm by underground drip irrigation arm buried depth that Chinese patent literature CN202588004U proposes, although can avoid the depth of implements of current rotary plow, but embedding position is excessively dark, operation is taken a lot of work, can cause moisture, nutrient to run off simultaneously downwards, reduce the effect of underground drip irrigation.
Along with the propelling of China's industrialization, urbanization process, the enforcement of land transformation policy, soil will be realized intensive production gradually, the operator can be more and more stronger for the technical need that can realize field production management mechanization, precision, economized.
