- Abstract:
-
With vacancy village reclamation, appropriate materials were used to improve the arability of cultivated land. The soil moisture content and water storage in the winter wheat fields with different added materials before winter were examined in order to choose better water-retaining property materials which can be applied to return to farmland in vacancy village reclamation. Under the four kinds of treatments of no returning material, organic fertilizer (fowl manure), fly ash and organic manure with fly ash, moisture contents were measured within 105 cm of soil profile using drying method during seedling, trefoil and tiller of winter wheat, which was measured in interval of 15 cm soil layer, and soil water storage in each growth period of winter wheat was calculated. The results showed that soil moisture content was different with different returning materials which were applied to vacancy village reclamation. Before overwintering of winter wheat, the average soil water content was 18.69% in each soil layer in 0—105 cm soil profile after the use of organic fertilizer with fly ash returning, which was higher than the single use of organic fertilizer (1.72%), fly ash (1.07%) and no returning material (2.84%), and water storage capacity of soil profile was also the largest that was 239.01 mm because organic fertilizer with fly ash was added to arable land of vacancy village reclamation, which was higher than the separate use of organic fertilizer (18.17 mm), fly ash (18.92 mm), no returning material (26.05 mm). Therefore, when vacancy villages are reclaimed as arable land, returning organic fertilizer with fly ash into the land in vacancy village reclamation is the best among the four kinds of treatments with respect to water use and water-retaining property, and the soil moisture condition.
