A kind of Prunella vulgaris herb residue floating seedling substrate and preparation method

Abstract

The invention discloses a selfheal dreg floatation seedling substrate and a preparation method thereof. The selfheal dreg floatation seedling substrate comprises 1 part of fermentative selfheal dreg, 0.5-1 part of earthworm excrement, 0-0.5 part of turf and 0.5-1 part of vermiculite. The preparation method is wide in the selection of raw materials, easy and convenient to operate and simple in process; the situation that the selection of the traditional substrate depends on non-renewable resources including perlite, vermiculite and the like is changed; the selected raw material is selfheal dreg abandoned by pharmaceutical factories, the seedling substrate is light in tactile sensation, and the porosity, volume weight and proportion of the substrate approximate to those of the turf, as a result, the pollution of the dreg to the environment can be solved, meanwhile, the waste dreg can be reused, and further the effects on environmental protection, energy economization and improvement of the utilization efficiency of humic acid are realized; the dreg is utilized as the main raw material of the seedling substrate, and the raw material is industrial waste residue, so that the cost is low, the preparation process is simple, and popularization and application are facilitated; the emergence rate of cabbages cultivated by utilizing the substrate can reach over 90 percent, the degree of uniformity of seedlings is high, the index of strong seedlings is also high, the growth is good and the cost is lowered.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to a substrate for floating seedlings of Prunella vulgaris dregs and a preparation method thereof. Background technique [0002] At present, vegetable seedlings generally adopt floating plug seedlings, and the seedling substrates are usually peat, perlite, vermiculite, etc. as the seedling substrates; the disadvantages of the prior art are: 1. Most of the substrates used by current commodities are non-renewable resource peat and the operation process Second, the cost of cultivation is relatively high, and it cannot get rid of the dependence on non-renewable resources; therefore, a new cultivation method is needed to solve the current problems. Contents of the invention [0003] The purpose of the present invention is to provide a substrate for raising seedlings by floating Prunella vulgaris dregs and its preparation method, which solves the problems of high culti...
