A Preliminary Study On The Construction Of Artificial Grassland Under Photovoltaic Frame

In view of the "central energy industrial park" photovoltaic abandoned under the rational use of cultivated land,Using the Medicago varia L.cv.CaoyuanNo.3?Medicago varia L.cv.Caoyuan No.2?Agropyron cristatum×A.desertorum cv.Mengnong?Bromus inermis Leyss.as materials.Applying fertilizer "water soluble fertilizer" and "beneficial microbial fertilizer",Using unicast and legume mixed treatment,determination of production performance of 4 forage PV frame,analysis of the re lationship between forage yield of 4 forage photosynthetic performance and different forage planting ways,screening in the environment suitable for planting grass,planting and fertilizer,provide the basis for the establishment of artificial grassland in photo voltaic frame under the.The results are as follows:1.Four grasses of light saturation point is greater than the pv under the frame of effective illumination intensity,but effective illumination time is only 4h-8h,Applying microbial fertilizer can improve the yield of forage,Under the condition of fertilization,the forage yield of 4-5h was higher than that of light irradiation time of 6h and 7h,Fertilization can compensate for the decline of forage yield caused by insufficient light.2.The beneficial microbial fertilizer is better than water soluble fertilizer,the application of microbial fertilizer could significantly increase 4 forage yield and seed yield of forage,and can significantly improve the plant structur.3.Under the special environment of the photovoltaic shelf shading and scattered light,Bromus Inermis Leyss.and Agropyron cristatum×A.desertorum cv.Mengnong of the 4 grasses.Than Medicago varia L.cv.Caoyuan No.2 and Medicago varia L.cv.Caoyuan No.3 can adapt to light environment under the frame of photovoltaic.The mixed sowing of leguminous forage grass and forage grass is better than unicast,The application of artificial grassland in the photovoltaic system use Bromus inermis Leyss.and Medicago varia L.cv.Caoyuan No.3 mixed sowing;Applying microbial fertilizer recommended when Medicago varia L.cv.Caoyuan No.2 and Bromus inermis Leyss.mixed sowing grassland or Medicago varia L.cv.Caoyuan No.3 of monoculture.
