不同农业废弃物配比基质对设施薄皮甜瓜生长、品质和产量的影响OA

In order to obtain the optimal substrate formula for the cultivation of oriental melon,the oriental melon Xing-tian No.20 was used as the experimental material,and 9 kinds of substrate formulas were used to explore the physical and chemical properties of substrates with different agricultural waste ratio and their effects on the growth,quality and yield of oriental melon.The results showed that substrate physicochemical properties of total nitrogen,total phosphorus,organ-ic matter and alkali-hydrolyzable nitrogen content were high when the ratio of mushroom residue to cow dung and sheep manure was 2∶1,which promoted the growth of crops.The oriental meloncultivated in 9 different matrix formulas showed good growth vigor with TP7 treatment(the volume ratio of mushroom residue,corn straw,cow dung,sheep ma-nure and furnace ash is 4∶1∶2∶1∶2),and the fruit vertical and horizontal diameter,soluble solids content and yield were the highest,followed by TP5 treatment(the volume ratio of mushroom residue,corn straw,cow dung,sheep manure and furnace ash is 3∶2∶2∶1∶2).The yield of TP7 treatment was 18.90%higher than that of CK,and TP5 treatment was 6.71%higher than that of CK.In summary,the mixed substrates treated with TP7 or TP5 can effectively improve the fruit quality of melon,increase the yield,and realize the recycling of agricultural and animal husbandry waste resources.
