- Abstract:
- In view of the problems of returning corn straw to the field by shallow rotary tilling and plowing under top soil directly, the experiment of corn straw central deep placing by machinery was conducted. In order to approach the soil moisture distribution status in different period, the soil moisture at different layer was monitored by TDR. The results showed that the large pore space have no effect upon corn seedling growth for having a proper distance between straw and seedling. The corn straw is in strongly absorbing water stage in the first year, the soil moisture at the position deep placing corn straw is decreasing with the increase of application dose. In the second year, the corn straw is also in absorbing water stage. The variation trend is similar to the first year, but the extent is less than the first year. The water content is being equilibrium between soil and corn straw by straw decomposition. The function for holding water and supplying water of corn straw in soil has been being appeared gradually. The soil moisture has always been unsaturated, therefore, the corn straw central deep placing by machinery must be on time and based on the moisture status of soil and corn straw, so as to blending through the water between the soil and straw and attaining the goal of holding water and fertilizer.
