TFT, also called Smart-farming, comprises four components, namely 1) soil series identification, 2) N-P-K testing by soil test kit, 3) fertilizer recommendations using decision-aids and a simplified version of a complex model and 4) farmer empowerment. The benefit of TFT at the rice field of the Huay Kamin chairman farmer group was one example, the technology has been disseminated to the 80 members with a total planting area of about 320 ha. The results revealed chemical fertilizer reduction of 69%, and rice yield increased some 10% - 20% with the improved fertilizer application method. The farmers were encouraged to establish “Soil Clinics” in their communities. In a Soil Clinic, designated and trained farmer leaders analyze soil samples for member farmers and provide TFT recommendations while providing access to fertilizer materials available for sale at competitive prices. At present, there are about 70 soil clinics in 20 provinces with the support of many government and private sectors.展开更多
为探讨测土配方施肥技术与常规施肥措施对桉树生长量影响的差异,为今后测土配方施肥技术在桉树种植中提供参考。试验地选取在广西壮族自治区国有博白林场射广分场射广工区4林班4.1小班内进行,用随机区组设计,选择立地条件相一致的地块,...为探讨测土配方施肥技术与常规施肥措施对桉树生长量影响的差异,为今后测土配方施肥技术在桉树种植中提供参考。试验地选取在广西壮族自治区国有博白林场射广分场射广工区4林班4.1小班内进行,用随机区组设计,选择立地条件相一致的地块,根据3种不同的施肥措施进行随机分组,分别为A、B、C组,其中A组采用测土配方施肥措施,B组采用常规施肥措施,C组为空白对照组,不采取任何施肥措施,3个处理,3次重复,并对各试验地桉树进行4次树高、胸径等相关指标调查。结果表明:根据A、B、C三组的平均单株材积换算成每667 m 2蓄积量,其中A组比B组的每667 m 2蓄积量增加12.2%,比不施肥的C组增加39.4%。可见与常规的施肥措施相比,采用测土配方施肥的方式能够有效提高桉树的蓄积量,提高桉树生产产量和经济效益。展开更多
