Title: Investigation on cropping patterns and their economic results of Shandong Province
Abstract: A detailed investigation on cropping patterns in Shandong province was conducted,the results showed nine kinds of cropping patterns existed in Shandong province,they were grain crop-grain crop,grain crop-economic crop,grain crop-forage crop,economic crop-forage crop and so on.The first three kinds of cropping patterns which had higher annual net income per hectare were grain crop-forage crop rotation mode,and the income of forage crops,the main components of the total income,was more than 4 times of the income of grain crops.In all these rotation modes,the economic benefit of wheat+Sudangrass whose annual income per hectare was 40 725 yuan was the highest,The economic benefit of wheat+ corn was the lowest whose annual income per hectare was 12 486 yuan.The three highest output-input ratio modes were grain crop-forage crop pattern,whose ratio were 2.76-3.03.In all cropping patterns,material cost and labor cost accounted for a large part of total input,30%-46.3% and 20%-53%,respectively;management fee accounted for a minimum part,the proportion is 18%-29%.Above all,in all cropping patterns,grain crop-forage crop pattern had a higher output-input ratio,forage and crop rotation should be extended to increase farmers' income and promote the development of animal husbandry in Shandong province especially in low-middle-yield cropland areas.
