According to unreasonable tillage measures and serious soil erosion on sloping land in Yunnan province

a trial of maize intercropping vegetable and grass strip was carried out to reduce the soil and water losses.The result shows: The runoff of maize intercropping potato in August is 37.4% less than maize sole and bare cropping.The sediment of intercropping cabbage in July and August is 46.7% and 58.2% less than maize sole and bare planting.The sediment of intercropping mixed grass strip in July

August

September and October is 68.9%

74.6%

84.5% and 82.1% less than maize bare planting significant(P <0.01).The total sediment of maize intercropping cabbage

potato and green pepper are 47.0%

43.8% and 10.2% less than maize bare planting significant(P <0.01).The total sediment of maize intercropping grass strip are 60.8% and 70.0% less than maize bare planting significant(P <0.01).The total runoff of maize intercropping potato is 21.0% less than maize sole and polythene mulch planting.The average sediment of intercropping is 35.7% less than maize bare planting in low rain rate

61.4% in medium rain rate and 70.0% in high rain rate.So maize intercropping vegetable and grass strip are some good kinds of water and soil conservation tillage measures

especially during high rain rate rainfall.
