Abstract

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.

Description

technical field

[0001] The invention relates to a cucumber plug seedling-growing substrate free of pouring nutrient solution and a preparation method thereof, belonging to the technical field of agricultural production. technical background

[0002] With the development of my country's vegetable industry and the advancement of industrialized agriculture, industrialized seedlings have gradually replaced traditional seedlings. At present, peat and peat are mostly used as seedling substrates in the industrial seedling raising process. These seedling substrates are mostly non-renewable resources. After years of mining, their reserves have been decreasing, and the development process has caused huge damage to the environment; peat is mainly produced in Northeast China and Southwest China has certain geographical restrictions, which increase the cost of seedling substrates such as peat and peat. Therefore, people began to look for new materials to replace seedling substrates such ...
