Cucumber plug seedling substrate free of watering nutrient solution and preparation method thereof

The invention provides a cucumber plug seedling substrate free of watering a nutrient solution and a preparation method thereof, belonging to the technical field of agricultural seedling cultivation. The preparation method comprises the steps of: mixing chicken manure and cow dung according to a volume ratio of 1: 4-16, and then inoculating earthworm for composting; after foodstuff is completely digested, obtaining loose and porous granulate earthworm cast with abundant nutrient elements and good air permeability, nutrient preserving capability as well as water-retaining property; and then mixing the earthworm cast with vermiculite according to a volume ratio of 2: 1 uniformly so as to obtain the cucumber plug seedling substrate free of watering a nutrient solution. The seedling substrate overcomes the disadvantages of low content of nutrient elements, unbalanced content of nitrogen phosphorus and potassium and insufficient supply of the common earthworm cast in the market. The experiment proves that the root activity, the strong seedling index, the dry and fresh weight of the plant and the output after the field planting of the plant cucumber seedling raised by the seedling substrate are obviously better than the traditional turf and vermiculite compound substrate which is watered with the nutrient solution. While replacing the turf, the seedling substrate realizes resource utilization of the excrement of animals and reduces environment pollution. Therefore, the cucumber plug seedling substrate free of watering nutrient solution has obvious economic benefits, social benefits and ecologic benefits.
