Abstract
The invention relates to a multi-ring salt pressing non-even irrigation device that is provided with a plurality of drip irrigation rings with the trunk as the center, wherein the diameter of the drip irrigation rings increases gradually. Drip holes are distributed at intervals in the drip irrigation rings, the total dripping amount of each drip hole of the drip irrigation rings increases gradually from the inside to the outside, and the drip irrigation rings are arrayed outwards sequentially 6-15cm inwards from the soil wet edge of adjacent inside rings; in lines or rows, all the drip irrigation rings at the same ring position are connected to the same capillary tube, all the capillary tubes at the same ring position are connected to the same branch tube, all the branch tubes are connected with a main tube, and valves are respectively arranged on the branch tubes and the main tube. According to the multi-ring salt pressing non-even irrigation device, on the basis of the principle that salts are accumulated at the wet edge of soil under the drip irrigation condition, a device and a method with the plurality of drip irrigation rings dripping water in a delay way sequentially are adopted to gradually press salts.
Description
Technical field
The invention belongs to agricultural technology field, relate to a kind of device improveing saline land, particularly relate to a kind of many rings and chase after filling device such as pressure non-grade.
Background technology
The salinization of soil is a global problem, nearly 1,000,000,000 hectares of saline land, whole world area, and China has 9,913 ten thousand hectares, is roughly equal to 14.7 hundred million mu, is mainly distributed in these arid and semi-arid lands of North China, northwest and northeast.In addition in cultivation, excessively for a long time use chemical fertilizer, cause soil secondary salinization to be aggravated, make salinization, alkali-affected soil constantly expands.
Conventional saline and alkali land improvement method comprises large hydraulic pressure salt and applying organic manure, but above method still has problems.Large hydraulic pressure salt improvement saline land needs a large amount of water, and the pressure salt water consumption on current secondary salinization ground is at 3000 ~ 4500m
3/ mu is not etc.; Apply fertilizer after large hydraulic pressure salt and also easily cause the accumulation of salt in the surface soil, according to investigation, 29, Kuerle, Xinjiang carries out improveing and planting cotton with large hydraulic pressure salt pair saline land for continuous 8 years, presses salt water consumption to reach 8000 ~ 10000 m in year
3/ mu, average annual fertilizing amount every mu be 100 ~ 120 kg not etc., after fertilising there is total crop failure situation in the accumulation of salt in the surface soil.
Summary of the invention
The object of the invention is to, for the problem that arid, semiarid zone shortage of water resources and the large hydraulic pressure salt water consumptions such as Xinjiang are large, propose a kind of pressure salt water yield, locally many rings of pressure salt saved to chase after and press the filling devices such as non-, and this automation equipment of filling with such as non-, to obtain better alkaline land improving effect.
The object of the present invention is achieved like this: many rings chase after filling device such as pressure non-grade, there are several centered by trunk, diameter drip irrigation ring from small to large, described drip irrigation ring has the drip hole be intervally arranged, in same time, the always amount of dripping of each drip irrigation ring is equal, and each drip irrigation ring is outwards arranged successively with the inside 6 ~ 15cm in ground moistening edge of adjacent inboard ring; To set in units of row or column, the identical all drip irrigation rings in ring position are all connected to same hollow billet, and all hollow billets with ring position are all connected to same arm, and all arms are all connected with main, and described arm and main are equipped with valve.
Further, on described all drip irrigation rings the size of drip hole and quantity all equal.
