| Abstract: | In order to eliminate soil salinity and improve the quality of severe salinized tide flat soil in short term, the integrated measures of farmyard manure and mulching, which are helpful for the soil water conservation, salinity elimination and crop growth, are introduced to regulate the dynamics of soil water and salinity. The results showed that farmyard manure plus polythene film mulch (FYM PM) and farmyard manure plus straw mulch (FYM SM) maintain soil water, restrain salt accumulation and promote crop growth effectively. However, the effects of the measures on soil pH are weak. The salt content is 2.88, 2.87 g kg-1 under FYM PM, FYM SM with a decreasing percent of 59.23 %, 59.40 % respectively and the moderate salinity degree, which has a positive role on the improvement of soil ecosystem. Compare to the control treatment, barley yield increased significantly with a percent of 55.95 %, 82.62 %, and the maize yield are 1916.59, 2484.13 kg hm-2 of FYM PM, FYM SM, with on yield in control treatment. It indicated that FYM PM and FYM SM increased the land productivity effectively, as both the yield of FYM PM and FYM SM are higher than the conventional cultivation of mild and moderate salinized soil. Besides, FYM SM is helpful for the sustainable use of farmyard manure and crop straw and relieves the environment problem of straw burning in the study area. In conclusion, it is significant to apply the integrated measures of farmyard manure and straw mulching in tidal flat area of north Jiangsu province. |
