通过田间试验，研究了麦收后塑料薄膜隔根小麦间作玉米（PW∥C）、尼龙网隔根小麦间作玉米（NW∥C）、不隔根小麦间作玉米（W∥C）与单作玉米（C）的干物质积累与分配及其产量的变化。结果表明，麦收后，间作玉米表现出极强的生长恢复效应，根系分隔弱化了间作玉米恢复效应。小麦收获时，单作地上干物质量较W∥C、PW∥C和NW∥C处理分别显著提高29．88％、62．51％和47．55％，PW∥C、NW∥C处理较W∥C处理分别降低20．07％、11．97％，Pw∥C处理比NW∥C处理降低9．21％；玉米收获时，W∥C、Pw∥C和NW∥C处理地上干物质量较单作分别显著提高25．83％、11．37％和20．80％，PW∥C、NW∥C处理分别较w∥c处理降低11．49％和4．01％，PW∥C处理比NW∥C处理降低7．80％。W∥C、PW∥C和NW∥C处理经济产量较单作显著提高71．97％、59．84％、58．24％，生物产量提高65．78％、58．OO％、58．98％。PW∥C、NW∥C处理经济产量分别较W∥C处理显著降低7．05％、7．98％，生物产量降低4．69％、4．10％。

Abstract： The changes of yield , dry matter and its distribution of intercropped corn after wheat harvesting were determined via a field experiment under the treatments of PW//C, NW//C,W//C and C. The results showed that there was a strong growth recovery effect for intercropped corn after wheat harvesting, whereas the growth recovery effect was weakened by root partition. When wheat was harvested, the drymatter weight of corn under W//C, PW//C and NWffC treatments decreased by 29.88%, 62.51% and 47.55% compared with sole corn, dry matter weight in the treatments of PW//C and NW//C decreased by 20.07% and 11.97% compared with W//C treatment , and dry matter weight in PW//C treatment de- creased by 9.21% compared with NW//C treatment;When corn was harvested, the dry matter weight in W//C, PW//C and NW//C treatments improved by 25.83 %if0, 11.37 % and 20.80 %, respectively, the dry matter weight in PW//C and NW//C treatments decreased by 11.49%ff0 and 4.01% compared with W//C treatment, and the dry matter weight in PW//C treatment decreased by 7.80% compared with NW//C treatment. The economic yields in W//C, PW//C and NW//C treatments increased lay 71. 970/60, 59.84%, and 58. 240/60 while the biomass yields decreased by 65.78%, 58.00%, 58.98%, respectively, compared with sole corn. Compared to W//C, PW//C and NW//C treatments, the economic yields decreased obvi- ously by 7.05% and 7.98%, while the biomass yields decreased by 4.69% and 4.10%, respectively.
