摘要
通过在橡胶园开展4种不同化肥减量增效技术试验,研究了不同化肥减量增效技术对土壤理化性状、橡胶树营养状况、橡胶苗增粗和橡胶树增产等方面影响。结果表明:4种措施均能保证橡胶树正常生长;有机肥替代化肥和绿肥(葛藤)覆盖在提高土壤有机质含量和改善土壤理化性状方面效果显著;有机肥替代30%化肥总养分、绿肥(葛藤)覆盖、配方施肥在促进橡胶苗增粗方面效果良好,其中绿肥(葛藤)覆盖、配方施肥试验效果显著;有机肥替代30%化肥总养分、缓控释肥、绿肥(葛藤)覆盖、配方施肥在促进橡胶树增产方面效果良好。
The effects of different chemical fertilizer reduction and efficiency increasing technologies on soil physical and chemical properties, rubber tree nutritional status, rubber seedling thickening and rubber tree yield increase were studied through the experiments of four different chemical fertilizer reduction and efficiency increasing technologies in the rubber plantation. The results showed that four measures could ensure the normal growth of rubber trees. Organic fertilizer instead of chemical fertilizer and green fertilizer(kudzu vine) mulching had significant effects in improving soil organic matter content, soil physical and chemical properties. Organic fertilizer instead of 30% chemical fertilizer nutrients, green fertilizer(kudzu vine) mulching and formula fertilization had a good effect in promoting the thickening of rubber seedlings. Among them, the effects of green fertilizer(kudzu vine) mulching and formula fertilization were remarkable. Organic fertilizer instead of 30% fertilizer nutrients, slow and controlled release fertilizers, green fertilizer(kudzu vine) mulching and formula fertilization had a good effect in promoting the yield of rubber trees.
