新型高效肥料对稻虾共作水稻生长和品质影响

Effects of Novel High Efficient Fertilizer on Paddy Growth and Quality of Paddy-Lobster Farm

摘要: 马来西亚低投入可持续发展联盟和湖北长江大学作研究，新型沸石肥料对稻虾养殖对水稻生长、产量、水质和水稻品质的影响。实验结果表明，处理组水稻的叶片SPAD (叶绿素)，分蘖数和LAI (叶面积)都较常规高，且在产量、千粒重、出米率、精米率均较常规肥处理高。在水田水质方面，样品pH变化较小。氨氮含量变化趋势不同肥料处理下基本一致，无显著差异，对水生物污染无重大污染顾虑。本研究成果能响应国家节肥减氮政策，同时适应当地政策，为稻虾互作模式提供新思路。

Abstract: Collaboration among Low Input Sustainable Agriculture Consortium (LISA), Malaysia and Yangtze University, Hubei China has launched novel zeolite fertilizer on paddy-lobster cohabitation field. Effects of the fertilizer on the paddy growth, yield, and water quality were recorded. The results indicated that treatment group performed better on SPAD chlorophyll, tiller number, Leaf Area Index. Performances on yield, thousand-grain weight and rice extractions were also better. pH and ammonia nitrogen of water remained same level as common treatment, which do not cause much pollution to lobster. This study is response to national agricultural policy on fertilizer saving and soil remediation in China and it is a new model for paddy-lobster farming.
