摘要
１９８９～１９９１年小区试验和多点大面积示范推广结果证明：果园化学除草比人工除草提高工效，见效快，节省人工和经费，提高果实产量和质量，实测每亩增产３８０ｋｇ，化学除草区内的果树叶中氮、磷、钾及钙等营养成分含量比人工除草分别增加２．４％，２３．５％，１３．６％，３．５％，果实中柠檬酸和糖分的含量分别增加０．０９％和０．２％，１等果率和着色率分别增加１８．０％和１．９％。
Through plot test and large scale exploitation in 1989￣1991, it has been proved that chemical weeding in orchard is for better than manual weeding in efficiency and result, saving and cost, increasing fruit yield and quality. In the practical measurement,the yield increase was 380kg per mu. the N,P,K, Ca contents in the fruit tree leaves increased by 24%, 23.5%,13.6%, and 3.5% respectively; lomonic acid and sugar contents in the fruit increased by 0.09% and 0.2% respectively; the lst grade fruit rate and colonring rate increasing by 18.2% and 1.9% respectively.
