Some features of the mechanization sowing afforestation in the acid sulphate soil region in the <\/b>Mekong<\/b>River<\/b>Delta.<\/b><\/p>\n
Acid sulphate soil area represents 1\/3 of the total 4 million hectares of land in the Mekong River Delta. Land preparation for afforestation in the acid sulphate soil region has its specific features and is an important step in the establishment of high quality forest plantation. This is a very hard job and is being carried out mainly by hand labour with the exception only in some cases where mechanization is applied. The use of machines in vegetation treatment brings about better results than doing by hand. (quality of the work as well as economic efficiency)In the construction of raised bands for Melaleuca leucadendron<\/i> plating the use of machines is much more effective than hand labour. For step by step implementing the mechanization of site preparation for forest planting to meet the increasing requirement in the sulphate acid soil region in the Mekong river delta, more attention must be paid to selecting the machines that are suitable to soil characteristics in this region at the same time improving tools for land preparation to meet the requirements of the silvicultural techniques and at the same time attain high economic efficiency.<\/p>\n","protected":false},"excerpt":{"rendered":"
