Poplar establishment and cultivation
During the second phase of project from 1998 to 2002, plantation activities with improved afforestation techniques were accelerated. Improved mechanized techniques for poplar included a Medium Depth Planter (MDP) and a Mechanized Auger Planter (MAP). In addition, research also studied various plantations established with different techniques on different sites and with different poplar clones. To help solve the problem of soil degradation caused by unsuitable agricultural practices in sandy lands in spring, the project identified an afforestation model of agro-forestry, characterized by zero tillage, deep planting, narrow tree shelterbelt and a double row of poplar. The project also established 200 ha of experimental and demonstration plots and over 10 000 ha of protective timber forests for various functions.
In 1992, 2 000 ha of P. simonii xiaozhuannica cl. "Baicheng-41" were planted on waste land in Tongyu Branch. Over 10 000 ha of sandy lands have been controlled and converted to farmland. With the protection of these farmland protection interventions, annual grain production surpassed the 4 000 kg/ha level. The local farmers expressed their appreciation of these plantations by calling them Sino-Belgian Protective Forests.
