- Abstract:
- Takyric solonetz is a kind of alkali soil with a high sodicity and poor structure,widely spreaded in northwest China.Using desulfurized gypsum as a kind of soil amendment on takyric solonetz to develop soil quality is of great importance to elucidate the mechanism of alkali soil recalmation.This study was based on a field experiment lied in Hetao irrigation district in Ningxia,China.The property of soil physics,soil chemistry under different treatments and Lycium chinense charactersitics including survival rate,individual height and yield were investigated to study the effects of adding structure krilium combined with desulfurized gypsum on alkali soil.The results showed that,the addition of desulfurized gypsum and structure krilium greatly increased soil organic carbon,total N,soil porosity and the content of soil water stable aggregate,respectively,while they decreased pH,total salt and volume weight at certain extents respectively.Therefore,the survival rate,individual height and yield of L.chinense were increased,and the improved effect increased with the amount of use increase.According to the degree of the local saline-alkali land and the cost benefit analysis of the L.chinense production process,the addition of T3 (300 kg·hm-2 krilium) was the optimum dosage in practical application.However,further experiment should be conducted to test application effect.The results provided scientific guidance for controlling the process of soil salinization in Hetao irrigation district and realizing the sustainable use of saline alkali soil.
