经多点调查和试验研究证明 ,泡桐与农作物间作能明显地改善农田小气候 ,为农作物生长发育创造良好的生态环境条件 ,促进农作物高产稳产。在每亩平均 4株左右泡桐与烟叶间作情况下 ,较非间作的增值 9.7% ,不仅经济收入提高 ,而且解决木材供需矛盾 ,值得大力提倡。 After many investigations and experimental studies have proved that Paulownia and crop intercropping can significantly improve the farmland microclimate for crop growth and development to create a good ecological environment conditions and promote high and stable crop yield. In an average of 4 plants per acre of paulownia and tobacco intercropping cases, compared with non-inter-value-added 9.7%, not only increased economic income, but also solve the contradiction between supply and demand of timber, it is worth vigorously advocating.
