Compound substrate for hot-pepper plug seedling and preparation method thereof

Abstract

The invention discloses a compound substrate for hot-pepper plug seedling and a preparation method thereof. The basic substrate is prepared from turf, corncobs, fine sand, pond silt, traditional Chinese medicine decoction dregs, edible fungus residues, microbial fermentation bacteria and other substrates through compound fermentation, an appropriate amount of other required nutrient substances is also added in follow-up different growth periods, and high-temperature disinfection and chemical disinfection treatment are performed before usage. Compared with a traditional compound substrate for the hot-pepper plug seedling, the fertility and physicochemical properties of the substrate are remarkably improved, the seed budding time is remarkably shortened, the budding ratio is improved, the emergence rate is remarkably improved, the quality of grown hot-pepper seedlings is high, the annual output of hot peppers is also increased, the seedling quality problem caused by uniform nutrition of the substrate for traditional hot peppers is solved, the existing troubles of hot-pepper plug seedling are decreased, the annual output of the hot peppers and the quality of vegetables are greatly improved, and economic benefits are increased for vegetable growers.

Description

technical field

[0001] The invention relates to vegetable planting technology, in particular to a composite substrate for seedling cultivation in pepper plugs and a preparation method thereof. Background technique

[0002] The existing hot peppers are mostly cultivated by direct seeding in field production. This cultivation method is easily restricted by the natural environment and climate conditions, and cannot be adjusted according to the needs of the growth and development of crop seedlings. The risk of failure is relatively high, especially when the peppers are mature. The planting period is relatively concentrated, the amount of seeds used for sowing is relatively large, and labor procedures such as thinning, replenishing, and setting of seedlings must be performed, so the planting cost of pepper cannot be controlled within a reasonable range.
