Description

technical field [0001] The invention relates to a salt discharge concealed pipe and a preparation method thereof, in particular to a salt discharge concealed pipe containing zinc oxide and a preparation method thereof. Background technique [0002] my country's saline-alkali land has a vast territory, and there are a lot of salt and alkali in the saline-alkali soil. The salinization of the land tortures the hard-working farmers and hinders the development of the economic society of the group farm. Since the treatment of saline-alkali land, we have never stopped exploring the treatment of saline-alkali land, and have explored treatment technologies such as high water pressure alkali, salt washing by planting rice, open ditch for alkali removal, soil replacement for salt removal, and deep loosening blasting. Problems such as high treatment costs, lack of water resources, and low land utilization rate have led to intensified soil salinization, severe secondary salinization of s...
