杨粮间作效益的研究
- Title:
- Studies on Intercropping Benefit of Poplar and Grain
- Keywords:
- poplar; intercropping; cumulation; benefit
- 分类号:
- F301.24
- 摘要:
- 通过进行相同密度不同林龄间作试验、相同林龄不同间作模式对林木生长的影响试验、杨树轮伐期内不同间作模式经济效益对比、不同间作密度对杨树生长影响试验，分析了杨粮间作的经济效益，得出了杨粮间作对提高林木生长量、提高农业收入具有重要作用，为开展杨粮间作技术推广提供了理论依据。
- Abstract:
- The effects of different intercrop modes and densities of poplar with grain on growth of poplar and net benefit were studied by field experiments and statistical analysis.The results showed that poplar intercropping with grain increase forest growth as well as agriculture income,providing theoretial basis for the technology spreading of intercropping poplar and grain.
