不同覆盖绿肥在云南开割胶园的生态适应性研究
Ecological Adaptability of Different Mulch Green Manure in Yunnan Tapped Rubber Plantation
摘要
Abstract
A field experiment was conducted to screen mulch green manure that can effectively conserve soil and water, improve soil fertility and make full use of low-light resources at tapped rubber plantation in Yunnan. The growth, biological characteristics, yield and covering effect of 40 kinds of leguminous green manure and their correlation were measured and evaluated. The results showed that 13 kinds of leguminous green manure had good ecological adaptability in tapped rubber plantation. Those green manure included A mphicarpaea linearis Chun & T. C. Chen, Calopogonium mucunoides Desv., Centrosema pubescens Benth, Chamaecrasta nictilans, Desmodium gangeticum(L)DC, Desmodium he.terocarpon(L.)DC, Desmodium laxiflorum DC, Desmodium ovalifolium, Indigqfera spicata Forsk. Pueraria lobata (Willd.)Ohwi, Pueraria phaseoloides Benth var. Javanica Baker, Shuteria hirsuta Baker, Tephrosia Candida DC. Dry matter accumulation quantity of bush was higher than herbage and vine. Soil and water conservation of herbage and vine were higher than the shrubs and bushes. To achieve the best mulching effect, bush, vine and herbs should be combined when screening mulch green manure. The long-term research should be founded to study ecological adaptability of different mulch green manure in Yunnan tapped rubber plantation in the future.关键词
