设置肥料试验和种植牧草绿肥试验.结果表明,施用有机肥料和适量化肥可使复垦地迅速形成生产能力;种植红豆草或紫花苜蓿对提高土壤养分肥力水平和改善表层土物理性状的作用十分明显.在短期内,以上两大项措施相当于当地一般耕种措施下复垦地十年以上的培肥功能.而任其自然的撩荒方式并不可取.
Fertilizer experiment and forage green manure experiment were set up.The results showed that the application of organic fertilizers and appropriate amount of fertilizers could rapidly form the productive capacity of reclamation land.The effect of planting sainfoin or alfalfa on increasing soil fertility and improving physical properties of topsoil was obvious In the short term, the above two measures are equivalent to the cultivation of more than a decade of land under reclamation land under the general cultivation measures in the region, and it is not advisable to let it be a natural approach to abandoning cultivation.
