在印度卡纳塔克邦试验了有或无滴灌施肥条件下腰果接穗产量情况。植株于1991年种植,1994年施肥,通过滴灌施用100％推荐量水溶性NPK(推荐量为500N:125P:125K 克/株·年),分4次等量施用;通过滴灌施用80％推荐量水溶性NPK,分4次等量施用;对照为无滴灌一次性施用100％推荐量NPK。结果表明,滴灌施肥处理的植株接穗产量高得多,1994/95和1995/96年度滴灌施用100％推荐量NPK的植株平均接穗数量为75.93个/株·年;滴灌施用80％推荐量NPK的植株平均接穗
In Karnataka, India, the yield of cashew nuts was tested with and without drip irrigation. The plants were planted in 1991 and fertilized in 1994. The same amount of water-soluble NPK (recommended amount 500N: 125P: 125Kg / plant · year) was applied in four equal doses by drip irrigation; The water-soluble NPK was applied in 4 equal doses. The control was a one-time application of 100% NPK without drip irrigation. The results showed that the yield of scion spiked by drip irrigation was much higher. The average scion number of NPK plants with 100% recommended drip irrigation in 1994/95 and 1995/96 was 75.93 plants / plant year; drip irrigation with 80% NPK Plant average scion
