Potato breeder's seed seedling-raising substrate and preparation method thereof

Abstract

The invention discloses a potato breeder's seed seedling-raising substrate and a preparation method thereof, and belongs to the field of potato breeding and planting. The substrate comprises 20-40 parts of loam compound, 5 parts of potash fertilizer and 65-85 parts of specially-made organic fertilizer, wherein the loam compound comprises loam and a recycled substrate, the specially-made organic fertilizer is prepared by fermenting fallen leaves, manure, potato stems and leaves, coal ash powder and rice bran through microorganisms, and the fallen leaves include 60-80% of pine needles. The substrate mainly comprises the loam, the recycle substrate and the specially-made organism fertilizer. The specially-made organic fertilizer mainly comprises the fallen leaf pine needles, the manure and the potato stems and leaves free of diseased plants. The loam and the recycled substrate are exposed in sun and dried at high temperature, and the specially-made organic fertilizer is fermented at high temperature, so most bacteria, insect eggs and seeds can be killed, and convenient, clean and fertile substrate soil is provided for potato breeder's seed seedling-raising. The component raw materials of the substrate are wide in source, waste is reused due to the recycled substrate and the potato stems and leaves produced in seedling raising, and the substrate is quite suitable for being used and popularized in potato seedling raising bases in suburbs and countries.

Description

technical field [0001] The invention relates to the field of potato breeding, in particular to a seedling-raising matrix of original potato seedlings and a preparation method thereof. Background technique [0002] Potatoes are perennial herbaceous crops that can be cultivated as annuals or twice a year. Potatoes have high nutritional and medicinal value. Planting potatoes has good economic benefits and market demand, and can be processed into starch, lactic acid, snack food, super absorbent resin, modified starch, bio-glue, etc. It can be widely used in various industries such as medicine, textile, casting, dyestuff, etc. [0003] The original potato seed is the seed potato originally produced by transplanting or cutting the virus-free test-tube seedling of the potato seed. Seed potatoes are small, and the standard requirements for the original seed are very high. (1) Can not carry any virus or viroid, (2) Can not be infected by fungal and bacterial diseases, (3) Mixing p...

AI Technical Summary

Problems solved by technology

[0004] Original potato seedling breeding is generally carried out in potato seed production bases. Greenhouse seedlings are used for seedling cultivation. Seedling cultivation substrates include soilless cultivation such as vermiculite and direct use of land soil for seedling cultivation. The high cost of the former substrate is not conducive to large-scale promotion, and the latter has soil viruses. Disadvantages of not being suitable for killing and insufficient fertility
