According to statistics, about 10 million hectares of land worldwide are abandoned due to soil salinization and soil salinization has become a worldwide problem. Heilongjiang Province, about 1.1 million hectares of saline-alkali land in low-yield field, how to effectively curb the process of soil salinity, increase investment in science and technology intelligence, transformation of low-yield saline-alkali land, tap the potential of grain production and continue to improve food production capacity, has become the province’s modernization of large An important proposition for agriculture. Preliminary estimates, such as the existing saline-alkali land transformed into paddy fields, rice can be added each year 50
