(续第7期第14页)4.稻田开沟技术传统紫云英开沟是晚稻收获后择晴天,采用人工或牲畜开沟。根据晚稻收获-紫云英稻田开沟一体化新理念,研制出与水稻联合收割机配套的大型稻田绿肥开沟装置,可调节入土角度的开沟犁,效率高,每天可开沟10公顷左右,且对田间水分含量没有要求。5.紫云英种子机械化收获通过改装现有水稻联合收割机,研发出收获紫云英种子的机械,实现了稻田绿肥作物种子收获过程轻简。在大田紫云英有75%~90%的荚角变黑时,田间清沟排水使得田间含水量少于40%。选择全喂入水稻联合收割机,并且将全喂入水稻联合

According to the new concept of integration of late rice harvesting-Ziyunying rice-field ditching, a large-scale open-pit green fertilizer ditching device matched with rice combine harvester is developed, which can adjust the ditching plow with high efficiency and can ditch 10 hectares per day , And no requirement for moisture content in the field. 5. Astragalus seeds mechanized harvest Through the conversion of the existing rice combine harvester, the development of the harvesting of the seeds of Asiatic seed machinery, to achieve a paddy field green manure crop seed harvesting process is simple and light. When 75% ~ 90% of the pods in the field are getting dark, the drainage in the field makes the field less than 40%. Select all-feed rice combine harvesters, and combine all-feed rice
