一、发展概况我国南方地区水田多,土质复杂,泥脚深浅不一,差异很大。另外,我国的农业机械化水平不高,下水田耕作的拖拉机数量少,有限的拖拉机大部分用在浅泥脚地区,因长年累月地工作,泥脚有逐年加深的趋势,有些地方拖拉机工作数年后,由于泥脚加深而影响机械耕整。拖拉机在泥脚超过30厘米深的水田无法工作,对于湖田、沤田、冬水田以及烂泥田更
I. Development Overview There are many paddy fields in the southern part of China. The soil is complex and the depth of mud is very different. In addition, the level of agricultural mechanization in our country is not high, and the number of tractors cultivated in the sewage fields is small, and most of the limited tractors are used in shallow muddy areas. Due to long years of work, mud feet have a tendency of deepening year by year. In some places, the tractors work for several years. Due to the deepening of mud feet, mechanical tillage is affected. Tractors cannot work in paddy fields where the mud is more than 30 centimeters deep, and they are more suitable for the fields of Hutian, Putian, winter paddy fields and muddy fields.
