为探究茭白种养模式的施肥策略，设置茭虾共作（ZC）、茭白单作（Z） 2个处理，研究茭虾共作对土壤氮磷含量、茭白产量和茭白干物质积累及氮磷钾吸收分配的影响。2021-2022年的研究结果显示，茭虾共作模式较茭白单作模式采茭期土壤中全氮、全磷、速效磷的含量分别提高了10.85%～38.89%、5.45%～13.79%、6.19%～61.79%，净茭产量提高了5.10%～19.54%，采茭期茭白茎、叶、净茭的干物质积累量分别增加14.41%～16.58%、10.28%～15.15%、10.57%～21.45%。2021年茭虾共作处理较茭白单作处理在采茭期叶的氮含量显著增加了25.74%，但在孕茭期茎中磷含量显著减少了16.76%;2022年氮肥减量、减量投喂下，茭...

Two treatments including co-cropping Zizania latifolia with crayfish(ZC)and Zizania lat-ifolia monoculture(Z)were set up to study the effects of co-cropping Zizania latifolia with crayfish on the content of nitrogen and phosphorus in soil,the accumulation of dry matter and the uptake and distribution of nitrogen,phosphorus,and potassium in Zizania latifolia to explore fertilization strategies for the plant-ing and farming mode of Zizania latifolia.The results of two years showed that ZC increased the content of total nitrogen,total phosphorus,and available phosphorus in the soil during the har...
