国内农业机械化设施存在的四大问题
时间:2012-10-15 来源:本站 作者:管理员

 

1、微耕机的多功能得不到充分的发挥如< ahref="http://www.hthlwgj.com">微耕机功率较小。
 
旋耕、深耕作业在深度和效率上达不到要求;加工工艺粗糙;旋耕刀不耐磨等质量问题。另外,由于微耕机的销售价格偏高,农民难以配齐各种机具,使微耕机的扶垄、覆膜、开沟、喷药、收获等多功能的发挥受到了限制。
 
2、棚机械卷帘机械化程度和技术亟待提高
 
目前全市安装手动卷帘设备的较多台套,而自动卷帘设备较少,已成为实现设施农业机械化的一大障碍。影响大棚机械卷帘设备推广的因素主要有技术问题和份格偏高。
 
3、棚内植保机械需要更新
 
目前用于棚内植保作业的机械仍然是背负式手动喷雾器,劳动强度大,作业效率低,雾化程度差,作业环境恶劣,尤其在病虫害多发年份,往往因工作效率低忙不过来而贻误了防治最佳时期,造成经济损失。微耕机(www.hthlwgj.com)配备药泵后可以进行植保作业,作业效果也比较好。但据了解,购买微耕机的农户很少有配备喷药泵进行植保作业的。
 
4、已有设施农业机械的品种不能满足用户需
 
性能达到农艺要求、适合设施农业栽培和收获等环节的农机具研制,在我国起步晚,有些还是空白。如小型钵苗移栽机械、采摘机械和农产品深加工机械等在我市农业龙头设施企业中有很好的应用前景,但市场上基本无此类产品。国外产品虽然技术成熟,具有性能稳定、功能齐全、便于操作等诸多优点,但一般价格较高,而且配件供应、维修服务等方面由于由经销商负责,无固定的售后服务部门,容易造成售后服务跟不上。既能体现国内产品低价格又能体现国外产品高性能的中间产品不多。
