			<p>今天龙钰机械来给大家说下<a href="https://www.llongyu.com/" target="_blank" rel="noopener noreferrer"><strong>拖拉机地膜覆盖机</strong></a>助推西南作区马铃薯生产技术~</p>
<p>1.优选良种。因秋季雨水多，宜选用结薯早、块茎膨大快、抗晚疫病、休眠期短的早熟或中熟品种，以30—50克脱毒小整薯为宜。<br />
2.种薯处理：拖拉机地膜覆盖机播前催芽，确保播种时种薯已发芽。根据当地土传病害情况选择农药拌种或喷洒。<br />
3.整地施肥。优先选择水稻茬或玉米茬。前茬收获后抢晴及时深耕细整地，作业深度以打破犁底层为宜，一般30厘米左右。播种前用机具或畜力浅耙作业。测土配方施肥或有机肥、无机肥结合施用。播种时沟施或穴施，化肥不与种薯直接接触，一般离种薯3—5厘米，然后覆土起垄，垄高15—20厘米。<br />
4.适期播种。<strong>拖拉机地膜覆盖机</strong>云贵较低海拔地区7月中下旬至8月上旬播种，川渝秋作马铃薯8月上旬至9月上旬播种。推荐采用单垄单行方式种植。依据品种特性合理确定种植密度，一般每亩4000—4500株。<br />
5.田间管理。肥水调控：播种时田间应三沟配套防湿害，注意清沟排渍防控涝灾。苗期结合中耕培土，每亩追施尿素5—15公斤。及时除草：一般播后出苗前，选择合适除草剂喷施到土层表面。也可以在马铃薯出苗后（3—5叶期）根据杂草选用除草剂，行间近地面喷施，尽量避开马铃薯植株。病虫防控：封垄后选择多种适宜药剂交替用药，预防和防治晚疫病3—4次。注意药剂防治土传病害。密切关注地下害虫，对地老虎、蛴螬、蝼蛄和金针虫等采用拌毒土或毒饵控制。<br />
6.适期收获。<strong>拖拉机地膜覆盖机</strong>一般在霜冻后或依据市场价格择期收获。选择晴天收获，剔除病、烂、畸形和带青头的薯块。根据市场需求，分级、定额包装或装箱上市。</p>
