摘要：

In order to explore intercropping to the physiological mechanism of continuous cropping obstacles in strawberry plant, by means of gas exchange technique and chlorophyll fluorescence transient technique, the influence of different intercropping on photosynthetic characteristics were studied by intercropping treatments of garlic, green Onions and Chinese chives. The results showed that the strawberry chlorophyll content of intercropping garlic treatment was the highest, and maximum photochemical efficiency (FVFm) and net photosynthetic rate (P-n) were also higher than those of contrast; The relative variable fluorescence (W-k) of acceptor side, relative variable fluorescence (V-i) of donor side of PS II in strawberry leaves were damaged in intercropping scallions, the function of photosynthetic apparatus was affected, and caused low photochemical efficiency. It shows that under high temperature, the promoting effect of intercropping garlic on physiological metabolism of strawberry was obvious. However, intercropping onion treatment was bad for its growth of strawberry.
