Eggplant seedling-raising substrate and preparation method thereof

Abstract

The invention belongs to the technical field of eggplant planting, and specifically provides an eggplant seedling-raising substrate and a preparation method thereof. The preparation method comprises the following steps: with lees of grape wine, Chinese medicine residue, poultry and livestock manure, corn straw powder, humus soil and a potassium-calcium fertilizer as raw materials, mixing the leesof grape wine and the Chinese medicine residue, adjusting an N / P ratio to be (4-6): 1, carrying out fermentation for 5 to 7 d, then adding the poultry and livestock manure and the corn straw powder, carrying out fermentation for 2 to 3 d, adding the potassium-calcium fertilizer, and carrying out fermentation for 7 to 10 d. The substrate provided by the invention can effectively prevent and treat common diseases and pests of eggplant seedlings, improves the survival rate of the eggplant seedlings, shortens the seedling raising period of eggplants, improves the quality of the eggplant seedlings,has low manufacturing cost and easily-available raw materials, and is an ideal eggplant seedling raising substrate.

Problems solved by technology

[0004] At present, there are many studies on eggplant seedling substrates in the prior art, such as a kind of eggplant seedling substrate disclosed in patent CN201510704645.8, using 4-8 parts of a mixture of biogas residue and gravel at 2:1, chicken manure 3- 5 parts, 1-2 parts of decomposed horse manure, 100-150g of nitrogen fertilizer, 200-250g of distiller's grains, 100-150g of potassium fertilizer, 80-150g of cinnamon stick powder, and 100-200g of light powder are added to each cubic meter of the above mixture. Although it effectively shortens the time from planting to harvest, its seedling raising effect is not ideal
