| Abstract: | The experiment in cotton stalk as manure was made.The result showed that the field fertilized with cotton stalk as manure with a quantity of 4 500 kg/hm~2 could maintain its normal OM level.Cotton stalk manure could decrease the soil bulk density,the soil hardness and the soil water content,and increase the whole porosity of the soil,the gaseous porosity and the effective elements content.Practically,the cotton stalk could be put into the soil with no grinding. |
