目前新疆自治区的农场所用的地膜覆盖机械大多是用24行播种机改装的。它不破坏原机结构,增加的铺膜部件均固定在一个附加梁上,可一次完成播种、铺膜两项作业。这种铺膜机具,由于采用先播后铺的工艺流程,出苗后,按株距在膜上打孔,把棉苗从膜里放出来,然后覆土密封。这种工序,要人工进行,劳动强度大,用工多,若放苗不及时,容易造成棉苗灼伤乃至烫死。下面介绍两种机器放苗的改装方法,供参考。 1.将先播后铺的工艺改为先铺后播、同时把条播改为穴播(图1)。即用原24行播种机完成施肥、整形、铺膜,其后面拖一组鸭嘴滚筒和覆土装置,完成打孔穴播和膜边及苗带的覆土。
At present, most of the plastic film mulching machines used in the Xinjiang Autonomous Region farms are converted by a 24-row seeder. It does not destroy the original machine structure, the additional membrane components are fixed on an additional beam, can be completed once sowing, filming two operations. This filming equipment, as a result of the first broadcast after the shop process, after emergence, according to plant spacing in the membrane perforation, the cotton seedlings released from the membrane, and then cover soil seal. This process, to be carried out manually, labor-intensive, labor and more, if the Fangmiao not in time, likely to cause cotton burns and even burned. The following describes the modification of two machines Fangmiao method for reference. 1. The first sowing shop process after the first shop after the broadcast, at the same time to broadcast broadcasts (Figure 1). That is to use the original 24 rows of planters to complete the fertilization, plastic surgery, film, followed by a group of duckbill drag and trowel device to complete the hole-punching and filming and seedling cover the soil.
