In order to improve soil environment in new reclaimed land and seek an appropriate tillage management for spring maize, a field experiment was carried out with four treatments of tillage practices, including the traditional tillage (CK), plastic film mulching (FM), straw burying (BS) and straw burying and plastic film mulching(FM+BS). The effects of different tillage on soil water content and fertility dynamics as well as spring maize yield were studied, the tillage managements were evaluated by gray multidimensional comprehensive feudatory degree evaluation. The results indicated that FM+BS increased soil water content at 0～60 cm and improved moisture distribution of soil profile at critical period for water requirement. The average soil organic matter content at 0～30 cm under BS was significantly improved. The yields under BS, FM and FM+BS were significantly higher than CK. The results of gray multidimensional comprehensive feudatory degree evaluation showed that the grade of CK, BS, FM and FM+BS were poor, general, fair and good. Therefore the FM+BS showed a distinct effect on soil water preservation and fertility promotion, which initially improved the soil environment of new reclaimed land and ensured a higher production of spring maize. The results can provide basis for researching appropriate tillage management for spring maize growth in new reclaimed land.
