摘要
由于油棕种植园的空果束倾倒面积有限,需要寻找一种环境可持续的空果束利用途径。据估计,100吨新鲜水果串(FFB)产生的EFB产量约为20%,相当于20吨。2015年,一项研究在Ladang Rakyat Trengganu Sdn拥有的一个有8年历史的油棕庄园进行。有限公司(LRTSB),位于登嘉楼的Cheneh。据估计,LRTSB棕榈油厂的年产量约为24万至25万吨乙醛,将生产约48万至5万吨乙醛。本研究在2015-2019年以60 t/ha (T1)、80 t/ha (T2)和0 t/ha (T3)的不同施用速率进行了EFB的施用。沿前堆(交替行)施用EFB,每年一次。收集的数据包括油棕产量、土壤化学性质和成本效益分析。结果表明,施用6年后,油棕产量较未施用油棕地有所提高。此外,EFB还有助于增加土壤养分含量、水分和减少土壤压实。总之,施用EFB提高了土壤肥力,提高了油棕产量。
Effects of Empty Fruit Bunch (EFB) Application on Oil Palm Yield, Soil Properties and Cost-Benefits Analysis
Due to limited area for dumping empty fruit bunch (EFB), an environmentally sustainable approach of EFB utilization is needed in oil palm plantations. The estimated production of EFB generated from 100 tons of fresh fruit bunches (FFB) is about 20%, which is equivalent to 20 tons. A study was conducted in 2015 at an 8-year-old oil palm estate owned by Ladang Rakyat Trengganu Sdn. Bhd. (LRTSB), located in Cheneh, Terengganu. It is estimated that the LRTSB palm oil mill’s annual production is about 240 000 – 250 000 tons of FFB that will produce about 48 000 – 50 000 tons of EFB. In this research, the application of EFB at different rates of 60 t/ha (T1), 80 t/ha (T2) and 0 t/ha (T3) were conducted from 2015-2019. The EFB was applied along the frond heap (alternate row), once a year. The data collected consisted of oil palm yield, soil chemical properties and cost benefit analysis. Results showed that after 6 years of EFB application, the oil palm yield increased when compared to the plot without EFB application. In addition, the EFB helped in increasing soil nutrient content, moisture and reduced soil compaction. In short, application of EFB increased soil fertility and improved oil palm yield.
