Study on the Adaptability of Corn Machinery and AgronomicRequirements in the Transition to Precision Agriculture

摘要

Corn is one of China's three major food crops, which sowing size and output ranked second in the world. The corn production and the quality requirements further enhance together with utilizing in food and feeding. In this paper, the status is analyzed such as the form of corn sowing, agronomic requirements and classification of corn harvesting machines. It is pointed out that the mechanization level of corn sowing-harvesting is crucial, and it is a very close relationship between sowing and harvesting machinery of corn and agronomic requirements. According to the current production pattern and the characteristic of corn widely distributed, the diversity of sowing-harvesting and the mechanization of our country, the principal contradiction and existing questions between sowing and harvesting machinery of corn and agronomic requirements are analyzed in following aspects. In order to make the corn farm transition to precision agriculture, and a higher-output ratio and the improving of environment, and efficient use of various types of agricultural resources, the achievement to economic and environmental benefits. In here, it is discussed about the lack of co-ordination in machinery and corn agronomic requirements and also it is made a number of views and suggestions in respect of the corn sowing patterns, the choice of maize varieties, and regional areas and large-scale cultivation.
