Description

A kind of sulfate type saline-alkaline pond constructing system and ecologic breeding implantation methods
Technical field
The present invention relates to ecologic breeding field, and in particular to is supported to a kind of sulfate type saline-alkaline pond constructing system and ecology Grow implantation methods.
Background technology
Saline-alkali water is the third water resource for being different from seawater, fresh water.The saline and alkaline water resource in China has 6.9 hundred million mu, divides extensively Cloth and rises in 19 provinces, municipalities and autonomous regions in China year by year.China is freshwater resources country in short supply, and multiple arid is given in recent years Agricultural production brings strong influence, therefore Ministry of Water Resources specify that the year two thousand twenty water total amount red line is no more than 670,000,000,000 cubes Rice, the utilization to unconventional water source propose higher demand.
China is large agricultural country, due to industrial development and traditional irrigation farming mode, causes the arable land in China gradually to subtract It is few, wherein because traditional irrigation makes agriculture plantation precarious with 3% speed Secondary Saline, 1,800,000,000 mu of arable land red lines.Although Country spends the rebuilding and improving of substantial amounts of human and material resources progress salt affected soil, but due to that can not solve to wash caused by rebuilding and improving Salt arranges buck, lacks long-term effect, produces little effect.
The fishery of development saline-alkali water is not only that utilization, the alleviation of unconventional water resource provide new approaches with water contradiction, And solve Saline-alkali Field Control transformation produce the desalinization of soil by flooding or leaching row buck problem of outlet, to promote China's Saline-alkali Field Control transform into Journey, promote Ecological Civilization Construction that there is important strategic importance.
At present, carry out plantation in some varieties in saline-alkali areas (such as the Northwest of arid) and cultivation task difficulty is larger.Together When, water channel is usually and directly poured water by breach to rice field at present, in water-pouring process, it has been found that in production period, water level mistake Height, low-lying land can not plant, and can also be easy to float even if rice transplanting rice shoot, root is difficult to be fixed on riverbed.
In addition, for the ecologic breeding of varieties in saline-alkali areas, can be good at will plantation and cultivation for not a kind of mode at present Combine.
The content of the invention
The development planted for the ecologic breeding of varieties in saline-alkali areas, we there is provided herein a kind of sulfate type saline-alkaline pond structure System is built, can be good at combining breeding and planting, concrete scheme is as follows:
A kind of sulfate type saline-alkaline pond constructing system, including
The outer canal of ring-type, one end of the outer canal of the ring-type are provided with the water inlet communicated with external water source, the other end be provided with The discharge outlet that outer row water channel communicates;
Division has a m*n block growing areas in the region that the ring-type irrigation canals and ditches surround, every piece of growing area include rice field and Ridge, circular groove and the Qu Geng being centered around successively from inside to outside outside the rice field, be provided between two pieces of growing areas of arbitrary neighborhood with The interior canal that the outer canal of the ring-type communicates, the ridge and the canal ridge offered sluice mouth;
M and n is the integer more than or equal to 2.
Further, water source is extracted by water pump and canal outside ring-type is delivered to by water inlet;And/or
In physical features higher than water source is provided with canal outside the ring-type, water source is delivered to ring by water inlet under gravity The outer canal of shape.
Further, at least both sides of the outer canal of ring-type are provided with drainage ditch, and outside the ring-type between canal and the drainage ditch Obstructed by road, the outer canal of the ring-type is communicated by being embedded in the hidden pipe below road with outer row water channel.
Further, each growing area connects the ridge of one end of the outer canal of the ring-type and the canal ridge offers Sluice mouth is crossed, and each growing area connects the ridge of one end of the interior canal and the canal ridge offered sluice Mouthful.
Further, each long 180-250m in the rice field, wide 80-120m;
On the basis of rice field, the high 0.2-0.4m of ridge, wide 0.3-0.6m;
Circular groove depth 0.8-1.2m;
The high 0.2-0.4m in the canal ridge, wide 0.8-1.2m;
The outer canal depth 1.8-2.5m of ring-type, wide 12-18m;
Interior width of the channel 6-10m, deep 1.8-2.5m.
Further, the outer canal of the ring-type is the outer canal of back-shaped ring-type.
Further, the outer canal of the ring-type and the interior canal are used to breed fish.
Further, being set up between adjacent two pieces of growing areas has bridge, and between each road and at least one piece of growing area Erection has bridge.
Ecologic breeding kind is carried out using above-mentioned sulfate type saline-alkaline pond constructing system present invention also offers one kind simultaneously Plant method, sulfate type saline-alkaline pond construction method, comprises the following steps:
Before the transplanting date of rice field, external water source conveys canal outside water to ring-type and the water level of canal outside ring-type is covered ridge and rice Field, rice field area is carried out to press the salt desalinization of soil by flooding or leaching, afterwards by below the water level primary emission in growing area to ridge;
During rice transplanting, water level is improved again, the water level of ring-type Wai Qu and interior canal is covered rice field and is not covered ridge, to rice Field carries out rice transplanting;
During paddy field cultivation manages, water level is reduced;
After rice harvesting, harvesting season autumn and winter drains the water of ring-type Wai Qu and interior canal, has drawn in the net fish.
The present invention can be good at carrying out ecologic breeding plantation operation in varieties in saline-alkali areas, while set twice in rice field periphery The ridge, circular groove is provided between the twice ridge, directly affecting for water body between water in a canal and rice field can be alleviated, while can prevent from producing The too high influence to rice field of phase water level, it also avoid fish and enter rice field;The drainage ditch specially set simultaneously, can play paddy field water Enter from external water source, be expelled to drainage ditch, realizing the water in rice field has into having, and prevents that soil is secondary saline and alkaline, so as to protect Protect operation soil.
