为培肥地力,实现7 500 kg/hm~2大肥量撒施有机肥,完成京郊2万hm~2基本农田综合治理工程,设计了上置链耙式有机肥撒施机,其特点是施肥量大、链耙上置和动力输出小。样机试验结果证明,基本满足生产需求,并小批量试制20台,较好地完成了基本农田大肥量有机肥施撒作业,为北京基本农田综合治理提供了强有力的装备支撑。
In order to cultivate fertility and achieve 7 500 kg / hm ~ 2 large amount of fertilizer application of organic fertilizer to complete the suburbs of Beijing 20,000 hm ~ 2 basic farmland comprehensive management project, designed on the chain Rake-type organic fertilizer spreader, its characteristics Is a large amount of fertilizer, chain rake on the home and power output small. The prototype test results proved that basically meeting the production needs and small-scale trial production of 20 units, and better completion of the basic farmland fertilizer application of large amounts of organic fertilizer, Beijing comprehensive management of basic farmland provides a powerful equipment support.
