玉米收获方式及其效益分析
Corn Harvest Methods and Benefit Analysis
摘要
Abstract
In order to provide theoretical basis and data support for further popularization of corn grain harvest technology and improve the mechanization level of corn production, the authors compared the labor use and costs input of different harvest methods, analyzed the benefit of promotion of corn mechanized kernel harvesting. In the form of interview and questionnaire, the authors investigated farmers'harvest methods of corn and the cost of different harvest methods in 4 provinces (regions), 16 cities (counties), 48 villages in the northeast and northwest spring corn area, and Huanghuaihai summer corn region, 465 valid samples were received. The results showed that there existed significant differences among regions in the adoption rate of corn mechanized harvest, the rate was the highest in Heilongjiang and Xinjiang, the adoption rate was above 89.4％, then was Henan of 58.1％and Jilin was the lowest of 21.5％. Comparing the harvesting efficiency and economic benefit of different corn harvest methods, technology of corn mechanized kernel harvesting was the most efficient, and it could save 300-600 yuan/hm2 and 900-1380 yuan/hm2 than that of mechanized ear harvest and artificial harvest respectively, which was a harvest mode that met the need of corn industrialization with less process, labor saving, low cost and high efficiency.关键词
