Abstract
An improver for saline-alkali soil is prepared from water depolymerizing maleic acid anhydride and water. Its advantage is low cost.
Description
The present invention relates to a kind of saline-alkali soil conditioner.
Saline-alkali soil is unfavorable for crop growth, causes the soil to fall into disuse or the underproduction.The patent No. is that the Chinese patent of ZL97115221.7 discloses a kind of Reyulation agent for saline-alkali soil, but the cost height, inconvenient operation.
Goal of the invention of the present invention is to overcome the deficiencies in the prior art, provides cost low, easy to operate a kind of saline-alkali soil conditioner.In addition compared with prior art, the present invention is more conducive to environment protection.
The present invention is made up of hydrolytic polymaleic anhydride and water, is 100 in the component gross weight, and the weight percent of hydrolytic polymaleic anhydride and water is: hydrolytic polymaleic anhydride accounts for 5-65%, and surplus is a water.
The preparation method of saline-alkali soil conditioner of the present invention is: hydrolytic polymaleic anhydride and water are mixed in proportion get final product at normal temperatures.
The present invention compared with prior art forms simply, and making method is simple, and cost is low, helps environmental protection.Saline-alkali soil conditioner of the present invention improvement salt affected soil is effective, and the saltings effect of increasing production after the improvement is reached more than 10%, is widely used in agricultural, forestry, afforestation etc.
Further specify the present invention below in conjunction with embodiment:
Example 1: by above-mentioned preparation method, make the saline-alkali soil conditioner of following weight percent: hydrolytic polymaleic anhydride accounts for 30%, and water accounts for 70%.
Example 2: by above-mentioned preparation method, make the saline-alkali soil conditioner of following weight percent: hydrolytic polymaleic anhydride 50%, water accounts for 50%.
Claims (1)
1, a kind of saline-alkali soil conditioner, it is characterized in that the weight percent of its each component is: hydrolytic polymaleic anhydride accounts for 5-65%, and surplus is a water.
