Since the high frequency of droughts and serious windy soil erosion in the aeolian sandy soil area of Western Heilongjiang Province

the conservation tillage measures of stubble-cutting

rotary tillage and notillage were employed.The effects of different tillage measures on maize growth and yields were studied comparing with the local traditional tillage.The results indicated that

tillage measures exerted more influence on maize growth in the late period of growth than the early period.The rotary tillage kept the soil with adequate water for the late period of maize growth and had the maximum production of maize

which is 31.2%higher than the traditional measures while the yield of taking stubble-cutting increased by 13% and that of no-tillage decreased by 20.4%.
