The results showed that the annual average natural rubber harvested area in Thailand increased by 1. 21% from 1980 to 1990; the annual natural rubber harvested area increased by 4. 27% from 1991 to 2011; the annual average natural rubber harvested area in 2012-2016 increased by 5. 65% per year; from 1980 to 2004,the per unit area yield of natural rubber in Thailand showed a rising trend,and rubber yield from 2005 to 2016 showed a decline trend; from 1980 to 2016,Thailand's natural rubber yield showed a wave-like rise. In recent years,natural rubber production has changed little. In 2015,the yield fell by 2. 19% compared with 2014,and in 2016 it increased by 0. 22% compared with 2015;from 1981 to 2016,the export volume of natural rubber in Thailand basically showed a trend of rising with large fluctuation. In recent years,the export volume of natural rubber in Thailand accounted for 74%-82% of natural rubber yield in that year. Finally,it is found that the harvested area of natural rubber in Thailand will continue to decline in the next few years,it is difficult to increase the yield,the proportion of natural rubber exports and yield will gradually decline.展开更多

In Malaysia,most rubber gardens are small,and the ratio of small rubber gardens to large rubber plantations is approximately 10∶ 1. In Malaysia,the plating area of rubber trees was only 4 200 ha in 1900,1. 30 million ha in 1961,and 1. 07 million ha in 2014. It was the highest in 1978,up to 1. 89 million ha. It was the lowest in 2010,only 1. 02 million ha. The per unit area yield of rubber in Malaysia was 6 074 hg/ha in 1961 and 6 274 hg/ha in 2014. The maximum 10 285 hg/ha appeared in 1987,while the minimum 5 492 hg/ha appeared in 1999. The per unit area yield of rubber in Malaysia fluctuated greatly. Rubber yield in Malaysia was 790 000 t in 1961,and it was the highest in 1988( 1. 66 million t) and the lowest in 2014( 670 000 t).展开更多

In the 1970 s,it became the world's largest producer and exporter of palm oil. To further explore the development prospects of the oil palm industry in Malaysia,this paper first introduced the development of oil palm in Malaysia,and analyzed the world's share of Malaysian oil palm harvested area,production,yield during 1980 and 2016. The results showed that the oil palm harvested area in Malaysia reached the peak value 5. 23 million ha in 2013; the yield of oil palm fruit reached the peak value98. 34 million t in 2015; the yield of oil palm fruit fluctuated between 14-20 t/ha; the ratio of Malaysian oil palm yield to world oil palm production reached its peak 51. 99% in 1989. Therefore,Malaysia should update the old oil palm plantation. The development of oil palm harvested area and yield has reached the peak value,it is difficult to increase the harvested area. The proportion of Malaysian oil palm industry to the world oil palm industry is constantly declining. In future,the per unit area yield of Malaysian fresh oil palm fruit is expected to reach a new peak,and fresh oil palm fruit will exceed 20 t/ha.展开更多
