摘  要：
传统铺膜播种机在地膜上打孔播种容易形成板结,不利于棉花这种破土发芽能力弱的作物生长。为此,通过改进2BP-2型滚筒铺膜播种机,采用内外滚筒组合式排种滚筒加装舀勺式取种器,使之适合棉花膜下半精量播种的要求。同时,参照单粒(精密)播种机试验方法,对棉花进行了正交试验。试验结果表明:播种棉花作业参数的较优组合为取种器个数4,机器前进速度为1.0m/s,充种容积为12.5%,此时可保证穴粒数合格率在9 0%以上,与规定粒距偏差不高于5%,播种平均粒数为4粒。

摘  要：
The traditional plastic film mulch seeder perforates on plastic film,which easily forms harden surface soil layer,it is not good at the growth of crops which have weak break ground ability. The 2BP-2 rolling filming planter was improved based on this,and the scooping metering device was adopted that it could meet requirements of half precision seeding for cotton; the structure parameters of main components are obtained by analysis of performance for the planter. Reference to the relevant national standard,the orthogonal experiments was arranged for cotton seed. Experimental results indicated that it is optimal when device number are 4,machine speed is 1. 0M / s and seed filling volume is 12. 5%,at which the qualified rate of seed number per is above 90%,the deviation of seed spacing is less than 5%,and the average seed number per is 4.
