Embodiment 2

[0017] Step 201: applying calcium sulfate powder to the soil of the saline-alkali land, performing ion exchange reaction with the salt in the saline-alkali land, and performing plowing and stirring to obtain a soft saline-alkali land;

[0018] Concrete, in step 201; Because the surface of saline-alkali land has a lot of saline-alkali separated out in the form of salt, mainly exists in the form of sodium carbonate, therefore, obtain easily soluble in water by reaction of sodium carbonate in calcium sulfate powder and saline-alkali land At the same time, after it is plowed and stirred, the saline-alkali land of soft soil is obtained, and it is applied to subsequent treatment. In the process of adding calcium sulfate, it is optional to add 2-4 tons on the surface of each hectare of saline-alkali land Calcium sulfate.

[0019] Step 202: adding water to the saline-alkali land with soft soil, dissolving the unreacted salt and the neutral salt obtained after the reaction, and perform...

Abstract

The method relates to the field of planting, in particular to a method for planting paddy rice on saline-alkali soil. The method includes: applying calcium sulfate powder to the saline-alkali soil, allowing the calcium sulfate powder to perform ion exchange reaction with salt in the saline-alkali soil, and ploughing to obtain soft saline-alkali soil; adding water to the soft saline-alkali soil to dissolve salt which is not reacted and neutral salt obtained after reaction, and irrigating to obtain slightly alkaline soil; applying base fertilizer produced by aerobic fermentation of composite biological bacteria, plant proteins, starch, trace elements and cow dung to the slightly alkaline soil so as to obtain the soil with the fertilizer; transplanting paddy rice seedlings to the soil with the fertilizer, and regularly spraying plant nutrient solution until the paddy rice is ripe. By the method, nutrient substance for paddy rice growth is provided, and high paddy rice yield is achieved.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a method for planting rice in saline-alkali land. Background technique [0002] In Northeast China, there are a lot of saline-alkali land; the soil in saline-alkali land is poor, and the organic matter and microbial components in the soil under the control of saline-alkali for a long time are low, which is not suitable for directly planting rice. Transformation, common transformation methods include: washing the ground with water, adding plant straw, microorganisms or chemical agents, etc. [0003] At present, the common method of planting rice in saline-alkali land is that the saline-alkali land transformed by the above method can directly plant rice; however, the yield of rice planted by this method is very low. Contents of the invention [0004] The object of the present invention is to provide a kind of method for planting paddy rice in saline-alkali land, to solve above-ment...
