| Abstract: |
| Seven compound cultivation modes in south of Horqin sandy land are chosen (A1:prunus armeniaca
//peanut / corn / peanut // prunus ameniaca; A2:prunus armeniaca // grain/ corn / grain // prunus ammeniaca; A3:prunus ameniaca// bean/corn/ bean//prunus ameniaca; B 1: prunus armeniaca//corn//prunus ammeniac; B2:prunus armeniaca// peanut// prunus armeniac; B3:prunus armneniaca // grain // prunus armeniac; B4:prunus ar-meniaca// bean //prunus armeniac) to study the variation of soil moiture and soil microbial biomass carbon in the sev-en modes and to evaluate the economic benefit in each mode. The results showed that the average water cotent of corn field throughout the growing season (0~40 cm) in fruit and grain compound cultivation was mode A1> mode A2> mode A3> mode B1, while the ffect on dwarf plants (0~20 cm) on interopping mode is insignificant. Soil microbial biomass carbon was mode A3> mode A1> mode B1> mode A2 on corn field; Soil microbial biomass carbon of intercrop-ping code is larger than that of the inteval-cropping for peanuts and beans on dwarf plant field, so is the intercropping code of corm and bean. Yield per unit area of corns in different compound cultivation modes: mode A1> mode A3>mode A2> mode Bl, production in intercropping corms and dwarf plants (peanut ，grain and bean) decreased by less than 5%，and the difference is insignificant. In terms of the economic benefits, both A1 and B2 exceed others. The conclusion is that A1 and B2 prove to be more productive modes on semiarid sandy and windy areas. |
