Optimized model of agro-animal husbandry for black soil region of Songnen Plain and its implementation effect

Abstract

Abstract: A 5 years study on the optimized model of agro animal husbandry for black soil region of Songnen Plain show that after implementing this model on the same area of farmland and with relatively stable cost, the total biological production (protein) of agriculture and animal husbandry, productivity of energy input, utilization rate of solar energy, and net income are 7.911× 10⁵ kg, 1.43, 0.40% and 3.2568×10⁶ RMB,increased by 68.4, 16.3, 48.2 and 75.5%, respectively.

Key words: Black soil region, Combination of agro-animal husbandry, Optimized model, Songnen Plain, soil nutrient, sand-fixation shrub plantation, soil quality assessment, soil microorganism
