今年在建点的同时,积极开展了烟草喷灌试验。初步试验表明,喷灌有明显的增产效果,说明预灌完全适用于烟草。试验地土质系中等肥力的中壤土,水源为机井,采用中原12c6型移动式喷灌机,其主要性能:喷头工作压力4公斤/厘米~2,喷水量:24.6米~3/时,射程33米,配带管径64毫米的聚氯乙烯硬塑管100米。田间布置喷点间距为45米。采用喷灌与沟灌对比试验法,喷、沟
At the same time of this year’s construction, we actively carried out the tobacco sprinkler irrigation test. Preliminary tests showed that sprinkler irrigation yield significantly increased, indicating that pre-irrigation is fully applicable to tobacco. Medium soil test soil fertility medium loam, water machine wells, using the Central Plains 12c6 mobile irrigation machine, its main features: nozzle pressure 4 kg / cm ~ 2, the amount of water spray: 24.6 m ~ 3 / h, a range of 33 M, with a diameter of 64 mm PVC rigid plastic pipe 100 meters. Spray point arrangement field spacing of 45 meters. Using sprinkler irrigation and ditch irrigation contrast test, spray, ditch
