Abstract

Based on agricultural biomass resources and utilization in Shaanxi province, this experiment used decomposing mushroom residues, pine needles, and peanut shells compounded with river sand as organic cultivation substrates, compared with garden soil, and carried out pot experiments to study the effect of different soilless cultivation substrates on tomato yield, size and number. The results show that compared with CK1 (garden soil) and CK2 (decomposed fungus residue: river sand = 1:1, volume ratio), the yield of greenhouse tomato of T5 (decomposed fungus residue: pine needles: peanut shells: river sand = 1:1:1:1, volume ratio) can be significantly improved; under the same amount of decomposed fungus residue and river sand, adding peanut shells has a better effect on tomato yield than adding pine needles; different treatments have little effect on the average height of tomato fruit, but have a greater effect on the cross diameter of the fruit.
