Abstract

The invention discloses a kind of salt-soda soil restorative procedure for being capable of Planting Crops, comprise the following steps：1）Rinse：Chisel one layer depth 1.8 2.9m irrigation canals and ditches are dug around soil to be repaired, one layer of cement plate is inserted on irrigation canals and ditches；Water is extracted using suction pump to be rinsed soil to be repaired, the cycle of flushing rinsed once for 6 10 days, continuous flushing 9 14 times.The present invention, which is realized, is constantly turned over and is sprinkled renovation agent to soil, is enabled to renovation agent and the soil layer in salt-soda soil well mixed, so that renovation agent can enter the bottom of soil layer, is easy to repair the salt-soda soil of ground depths；Simultaneously when the later stage is in Planting Crops, to the continuous measurement salinity in salt-soda soil, it can effectively ensure that crops can be grown in the early stage, will not be not deep because of root system at initial stage, because salt content is too high and be dehydrated and die in soil；So as to effectively ensure that the crops in later stage can improve the salt content in salt-soda soil.

Description

It is capable of the salt-soda soil restorative procedure of Planting Crops

Technical field

The invention belongs to land remediation technical field, more particularly, to a kind of salt-soda soil reparation side for being capable of Planting Crops Method.

Background technology

Salt-soda soil is a species of salt aggregation, refers to that the salinity contained by inside soil has influence on the normal life of crop Long, from soil texture, salt-soda soil is all knotts clay, and gas permeability, the seepage of water of soil are very poor, and salinity is blended in knotts clay In, it is difficult to be separated, cause and precipitate year by year, saliferous more and more higher, but existing salt-soda soil is repaired when repairing Not thoroughly, all it is often the soil property on rehabilitating soil surface；After the time one is grown, the salinity of the soil of bottom will come back to Top layer；All it is directly that but crops are in seedling by proportion of crop planting on salt-soda soil simultaneously in conventional repair process Phase root system is not deep, and survival ability is poor, and the salinity among salt-soda soil is easy for that crops can be allowed to cross higher position dehydration because of salt content Die, often cause proportion of crop planting to fail.

The content of the invention

There is provided a kind of salt for protecting crop growth to be capable of Planting Crops in order to overcome the deficiencies in the prior art by the present invention Alkali ground restorative procedure.

To achieve these goals, the present invention uses following technical scheme：Repair in a kind of salt-soda soil for being capable of Planting Crops Compound method, comprises the following steps：

1）Rinse：One layer depth 1.8-2.9m of chisel irrigation canals and ditches are dug around soil to be repaired, one layer of cement plate is inserted on irrigation canals and ditches； Water is extracted using suction pump to be rinsed soil to be repaired, the cycle of flushing rinsed once for 6-10 days, continuous flushing 9- 14 times；

2）Deep ploughing：Soil memory to be repaired is turned over, the process turned over needs progressively to be turned over to center from periphery；Turning over Plough and soil to be repaired is plowed using ploughing machine after completing；Soil to be repaired is carried out again after completion of plowing Secondary flushing；Rinse complete after using sprinkling renovation agent；

3）The configuration of renovation agent：From 9-14 parts of calcium oxide, 7-19 parts of silica 1,6-10 parts of aluminum oxide, sulfur trioxide 1.3- 1.7 parts, 2-4 parts of iron oxide, 0.6-1.9 parts of magnesia, 0.7-1.6 parts of titanium dioxide, 0.9-2.0 parts of potassium oxide, manganese oxide 50-67 parts of 0.3-0.7 parts, 5-9 parts of sodium oxide molybdena and water are mixed, and then stand three days, then barrelling is stand-by；

4）The reparation in salt-soda soil：By step 3）In renovation agent be spread on salt-soda soil to be repaired, then using ploughing machine to soil Ground is turned over, and causes soil dry in drying in the sun after completion is turned over, the soil dried is turned over again, Turn over the crop for planting Salt And Alkali Tolerance after completing on soil；The initial stage for the crops planted constantly tests containing for salt-soda soil Crops are irrigated by salt amount when salt content is high.

Further, step 4）Described in dry need dry untill soil superficial drying；It is dry to top layer by drying It is dry, also in moisture state below its top layer, therefore it is easy to turning over for later stage, while also ensureing that the renovation agent of underground will not can Saline and alkaline in soil is repaired.

Further, need manually to screen out the organic matter for being difficult corruption during turning over；By manually screening out not The organic matter easily degenerated, can ensure in soil to be not in the material do not degenerated when later stage farming, so that it is guaranteed that planting The plant of plant can be deep into underground and be absorbed to more nutrient, while protecting environment.

In summary, the present invention, which is realized, is constantly turned over and is sprinkled renovation agent to soil, enables to repair The soil layer in agent and salt-soda soil is well mixed, so that renovation agent can enter the bottom of soil layer, is easy to the salt to ground depths Repaired alkali；Simultaneously when the later stage is in Planting Crops, to the continuous measurement salinity in salt-soda soil, can effectively it protect Card crops can be grown in the early stage, will not be not deep because of root system at initial stage, because salt content is too high and be dehydrated and die in soil；So as to The effective crops for ensureing the later stage can improve the salt content in salt-soda soil.
