Abstract
Experiments were conducted to research on four cultivation measures of autumn rotary tilling, deep loosening, spring rotary tilling and no tillage as well as the effect of inter- tillage on photosynthetic characteristics, water utilization efficiency and yield of soybean at initial bloom stage in west arid district of Heilongjiang Province. The results showed that no tillage and deep loosening could effectively enhance photosynthetic rate and water utilization efficiency of soybean, delay degradation of chlorophyll and increase the accumulation of dry matter. Inter- tillage could reduce the photosynthetic rates of 0.8 - 1.28 μmol m-2 s-1 and water efficiency reduction was up to 12%, which is harmful to crop drought resistance. Two- year yield data showed that no tillage and deep loosening, not being inter- tillage could significantly improve soybean yield of this area, and the maximum yields reached 18.3% and 32.2%. In arid years, traditional rotary tilling, especially spring rotary tilling and inter- tillage could reduce soybean yield in different extent, which is unsuitable for agricultural cultivation of this area.
