| Abstract: |
| An experiment was conducted to study the effect of maize and erect milkvetch interplanting on soil mois-
ture and yield throuth pure maize planting, pure erect milkvetch planting，maize/ erect milkvetch interplanting(2:1),
maize/erect milkvetch interplanting(4:2), and maize/ erect milkvetch interplanting(2:2). The results indicate: The
maize/ erect milkvetch interplanting has certain influence on spatial and temporal changes of soil moisture, and the sea-
sonal change tendency of soil moisture is obvious, from top to bottom, increasing along with the soil layer depth, and the soil moisture content displays a tendency of“increasing first and then decreasing”. The maize/ erect milkvetch interplant-ing dose not have remarkable influence on maize height, but has remarkable influence on the height of erect milkvetch, while the difference of plant height changes the maize’s aeration and photopenetration conditions. The maize/ erect
milkvetch interplanting(4:2) may affect the dry matter accumulation speed of maize and prolong the peak time thus main-tain a longer period of fast growth. For the maize yield characters, the length and diameter of ears, grain number per row and row number are not much different under various treatments, but 100- grain weight is significantly different, and the
yield achieves extremely remarkable difference, of which the greatest is pure maize planting, as much as 15 567. 50
kg/hm2，while that of maize/ erect milkvetch interplanting(2:1) is the lowest, as low as 11 238.33 kg/hm2. As a whole, the patterm of the maize/ erect milkvetch interplanting(4:2) may be extended in west Liaoning area. |
