Abstract: Takyric solonetz land, a typical subclass of alkali soil, is widely distributed in the North of Yinchuan Plain of Ningxia province, West Hetao Plain and north Xinjiang desert steppe in China. Due to the hard texture and poor permeability, it has become the main factor severely affecting the development of local agriculture, and is expected to bring threat to the regional food security in the future. More and more improvement techniques have been developed to achieve a sustainable utilization of saline-alkali waste land, but the effect of leaching, gypsum, furfural residue and their interaction on soil properties and yield of oil sunflower in newly reclaimed crack alkaline land remains unknown. In order to investigate the effect of leaching, gypsum and furfural residue on soil properties and yield of oil sunflower planted in newly reclaimed takyric solonetz land, a comparative field experiment in 2012 was conducted at the farmland of Ningxia Xi Da Tan of China (106°24'209"E, 38°50'289"N). Three leaching amount (3600, 4500 and 4800 m3/hm2) and four application rate of furfural residue (0, 15, 22.5 and 30 t/hm2) were designed. Besides, the desurlphurized gypsum (28 t3/hm2) was applied in combination with furfural residue. Then, measurements were made for soil physical and chemical properties, soil salt ions and yield of oil sunflower of different treatments. The test items were soil pH, total salinity, alkalinity, total alkalinity, salt ions, water holding capacity of soil, water permeability of soil and germination days, germination rate, survival rate, height, stem diameter, head diameter and yield of oil sunflower. The results showed that soil pH, total salinity, alkalinity, total alkalinity and salt ions were significantly reduced in the soil of layer 0-20 cm（P<0.05）under the leaching water volume of 4500 m3/hm2 and furfural residue (22.5 t/hm2). The pH, alkalinity, total alkalinity and salinity of soils were decreased from 9.65，38.4%，0.51cmol/ kg and 5.38 g/kg before experiment to 7.6, 15.3%, 0.31 cmol/kg and 1.66 g/kg after experiment, respectively. They were decreased by 21.2%, 60.2%, 39.2% and 69.1%, respectively in the soil of layer 0-20 cm. These changes facilitated the germination and growth of oil sunflower, thereby increasing yield. Among all the treatments, the combination of leaching water volume of 4500 m3/hm2 and furfural residue 22.5 t/hm2 was best with the highest oil sunflower yield of 3195.8 kg/hm2. In addition, after application of furfural residue and desurlphurized gypsum, the Na+ in 0-20 cm decreased greatly but increased in 40-60 cm. Similarily, Ca2+ also was accumulated in 20-60 cm. Mg2+, K+, Cl-, SO42- were also increased in the soil layer of 0-60, 0-60, 60-80, and 40-60 cm, respectively. It was highly likely due to low water permeability of takyric solonetz land. In order to improve the effect of leaching over a field, the clay layer deep in soil profile should be loosened at lease to 80 cm, which could increase soil water infiltration rate and depth and discharge soil salt ions to avoid salt accumulation in deep soil and then returning to the soil surface by evaporation. The findings of this study will provide technical support for improving the newly reclaimed takyric solonetz farmlands and controlling water and salt, and provide data support for the development of irrigation systems. In sum, it suggests that gypsum (28 t3/hm2) combined with furfural residue (22.5 t/hm2) and leaching (4500 m3/hm2) and soil loosened to 80 cm is the better way to improve newly reclaimed farmland takyric solonetz soil.
