- Abstract:
-
A technique of fleetly upgrading productivity of serious eroded black farmland was studied in this paper.Contour planting,deep plowing,cattle manure applying and high yield soybean breed sowing were integrated in a slope steepness 4.1° serious eroded black farmland.The results showed that soil erosion was greatly decreased,soybean grain yield increased from 1 335kg/hm2 to 2 518kg/hm2,mean increase rate was 89.7 percent,from 19.7 to 172.4 percent in the whole slope farmland compared with the former farmland which no soil and water conservational managements.The farmland became from low to high yield in one year.The key obstacle factor of low productivity in serious eroded black farmland was soil moisture intimidation.Hence,water conservation was the key measure to upgrade productivity of serious eroded black farmland.Runoff could be greatly reduced by contour planting and deep plowing,which might increase soil moisture and water use efficiency.This technique will be benefit to soil and water conservation and crop yield increase in the black soil area of northeast China.
