Grape organic cultivating substrate and preparation method thereof

Abstract

The invention discloses a grape organic cultivating substrate. The grape organic cultivating substrate is prepared from the following materials in parts by weight: 15 to 30 parts of tea bran, 15 to 30 parts of peanut bran, 15 to 30 parts of wheat bran, 10 to 15 parts of seaweed meal, 10 to 15 parts of shell powder, 40 to 60 parts of bentonite, 20 to 30 parts of coconut shell, 50 to 100 parts of rotten leaf soil, 250 to 350 parts of yellow soil, 100 to 200 parts of sludge, 50 to 100 parts of banana stalks, 1 to 2 parts of saccharomycetes, 1 to 2 parts of bacillus, 10 to 20 parts of a flocculating agent, 20 to 50 parts of earthworm powder and the like. According to the grape organic cultivating substrate disclosed by the invention, the benonite, the rotten leaf soil, the yellow soil and the sludge are utilized as main substrate sources of the grape organic cultivating substrate, heavy metal elements in the grape organic cultivating substrate can be subjected to peptide chain chelating through an added earthworm powder extracting solution to form macromolecules and then can be removed through the flocculating agent, the content of heavy metal in the grape organic cultivating substrate can be remarkably reduced, and safety of grape planting is increased.

Description

technical field [0001] The invention relates to the field of grape cultivation. More specifically, the present invention relates to a grape organic planting substrate and a preparation method thereof. Background technique [0002] Grapes are not only delicious, but also have high nutritional value. The sugar content in ripe berries is as high as 10-30%, mainly glucose, which can be directly absorbed by the human body. It also contains minerals calcium, potassium, phosphorus, iron, multivitamins and essential amino acids for human body.

Problems solved by technology

The planting substrate plays a key role in the cultivation of grapes. At present, the planting bases of grapes are generally mountainous areas, and the soil in mountainous areas is poor, which is not conducive to the growth of grapes. Fertilization can only be applied later to promote the rapid growth of grapes, resulting in the transformation of organic matter in grape fruits. low rate, low sweetness
