The Distribution And Resource Evaluation of Typical Energy Plants (Jatropha curcas L.) in Guangxi, China

Jatropha curcas L. is an important resource for bioenergy. There are many kinds of energy plants in the world, but they are not utilized sufficiently. Because of the lack of knowledge on resource numbers and distribution of energy plant limited their development. In this paper, we discussed the natural distribution of Jatropha curcas L. in Guangxi province. At the same time, we carried out assessment on the energy plant resource numbers of Jatropha curcas L. in Guangxi. At last, we provided some suggestions for developing of Jatropha curcas L. in China.

The world is facing energy crisis and the search for renewable bio-energy is currently one of the most important issues. Energy plant as a kind of bio-energy feedstock has attracted more and more attention, especially its planting issue. Short rotation coppice (SRC) is used as a proxy for other energy plants. This paper investigates farmers’ planting decisions of SRC under the threat of regulatory taking which is rarely mentioned in the previous relevant literatures. We use real options approach and especially take the risk of regulatory taking into account to analyze whether or not to grow SRC instead of traditional crops on farmland. It turned out that the threat of regulatory taking reduces the investment threshold and stimulates farmers to grow SRC. In other words, the threat has potential to improve the development of bio-energy.

Jatropha Curcas L

Indonesia memiliki banyak tanah masam, tetapi penggunaan masih sangat sedikit karena kandungan nutrisi tanah masam rendah. Sementara itu, jarak pagar merupakan tanaman yang dapat tumbuh di berbagai jenis tanah (termasuk lahan marjinal) dan penggunaannya sebagai bahan baku biodiesel. Oleh karena itu, perlunya penelitian mengenai pertumbuhan jarak pagar pada tanah masam sebagai upaya untuk mengembangkan jarak pagar dan penggunaannya di Indonesia.Untuk memulai upaya, penelitian tentang berbagai genotipe jarak pagar di tanah masam telah dilakukan. Tujuan dari penelitian ini yaitu mempelajari genotipe jarak pagar yang berpotensi untuk tanah masam. Penelitian ini dilakukan di UPTD Pengembangan Teknologi Lahan Kering Singabraja, Kecamatan Tenjo, Bogor, Jawa Barat, dari November 2010-Agustus 201. Penelitian ini menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) dengan satu faktor yaitu genotipe. Hasil penelitian menunjukkan berbagai perbedaan pada pertumbuhan diantara genotipe-genotipe jarak pagar. Secara umum, ada lima genotipe jarak pagar yang terbaik di tanah masam (pH 5.0) yaitu Medan I-5-1, Dompu, IP-2P-3-4-1, Sulawesi, dan Bima M.
