Comprehensive evaluation of facility melon compound substrate based on membership function method
The research aimed to screen out the substrate formula of facility melon cultivation with agricultural waste as the main raw material,so as to provide reference for the substrate cultivation technology of facility melon.Taking cow dung,sheep dung,mushroom residue,rapeseed oil residue and perlite as raw materials,six treatments were set up accord-ing to different volume ratios.The effects of different matrix formulations on plant height,stem diameter,leaf number,SPAD,fruit morphological index,yield and fruit quality of melon during growth period were studied.The results showed that under T3 treatment(cow dung∶mushroom residue∶rapeseed oil residue∶perlite=4∶3∶0.5∶2),the plant growth and leaf SPAD of melon during the whole growth period were significantly better than those of other treatments,and the increase in seedling stage was the largest.The yield of melon,vitamin C content,soluble sugar content,soluble solids content,solid-acid ratio and sugar-acid ratio were significantly higher than soil cultivation(TR)and commercial substrate(CK,peat∶vermiculite∶perlite=1∶1∶1),and the organic acid and titratable acid content were significantly lower than CK and TR.The average value of membership function was 0.920,which was higher than that of other treatments.In summary,under T3 formula,melon has the best growth status and T3 is more suitable as a cultivation substrate for facility melon.
