[Objective] The effects of solonchak-improved fertilizer on meadow solonchak and economic benefit of sugar beet was researched by applying it in Hexi corridor of Gansu Province

in order to provide technical support for the sustainable development of beet industry in this area.[Methods] The study was conducted on the meadow solonchak in Huajian Town

Suzhou District

Jiuquan City

Gansu Province through field experiment.[Results] The order of raw materials impacting sugar beet yield were solonchak agent

special fertilizer of sugar beet

organic carbon fertilizer. The formula components of solonchak amendment fertilizer were as following

the special fertilizer of sugar beet was 0.0586

solonchak agent was 0.0623

organic carbon fertilizer was 0.8791. The amount of solonchak-improved fertilizer was positively correlated with indices of porosity

aggregate

water holding

organic matter

available nitrogen

phosphorus and potassium

sugar beet agronomic trait

economic trait and yield; and was negatively related with soil bulk density

pH value and total salt content. Statistical regression showed that the optimum application amount for economic benefit was 39.64 t/hm2

at that application level

yield of sugar beet roots would be 96.68 t/hm2. The benefits from solonchak-improved fertilizer got 414.48

946.10 yuan/hm2 increases as compared with the benefits from two traditional ameliorants named Kangyanfeng and Wofenglong.[Conclusion] The application of solonchak-improved fertilizer can improve the physical and chemical properties of the meadow solonchaks and increase the soil enzyme activity and the yield of beet.
