摘要
为探索“玉米田养鹅”生产模式对系统碳截获量的影响,通过对比试验方法进行田间试验,结果表明:玉米田养鹅处理对玉米干物质积累和碳同化能力无明显影响;常规处理中除草剂降低了杂草的拮抗作用,其系统总干物质积累和碳同化量均较高;在生殖生长阶段,由于杂草对资源的竞争使对照下玉米的干物质积累和碳同化量显著低于常规处理。总的来看,玉米田养鹅处理对杂草群落控制效果显著,鹅采食杂草后所转化的粪肥是间接的同化碳投入,潜在增加了系统碳同化量。
In order to explore the impact of the “raising geese in cornfield” production model on the system carbon interception, the field experiment was carried out by comparative test method. The results showed that the corn field goose treatment had no significant effect on the dry matter accumulation and carbon assimilation ability of maize, and herbicide reduced the antagonism of weeds, and the total dry matter accumulation and carbon assimilation of the system were higher. In the reproductive growth stage, the dry matter accumulation and carbon assimilation of corn under control were significantly lower due to the competition of weeds on resources for routine processing. In general, the corn field goose treatment had a significant effect on the weed community control. The manure that was converted after the geese feed the weeds was an indirect assimilation carbon input, potentially increasing the system carbon assimilation.
