Feed for tuber expansion period of bletilla striata and preparation method of feed

Abstract

The invention relates to feed for a tuber expansion period of bletilla striata and a preparation method of the feed, and relates to the field of fertilizer. The feed for the tuber expansion period of the bletilla striata is prepared by the following method: based on the weight percent of pure nutrients, mixing 16 percent to 18 percent of nitrogen, 16.5 percent to 17.5 percent of phosphorus, 8 percent to 10 percent of potassium, 0.1 percent to 0.3 percent of selenium, 0.5 percent to 2 percent of medium trace element fertilizer and 5 percent to 8 percent of organic fertilizer; granulating, spraying a film coating agent and drying. The feed provided by the invention has balanced nutrients, and aboveground nutrient substances can be effectively conveyed into the ground, so that the tuber expansion of the bletilla striata is effectively promoted, and accumulation of the nutrient substances is carried out, and furthermore, the yield of the bletilla striata is improved. The preparation method of the feed for the tuber expansion period of the bletilla striata comprises the following steps: based on the weight percent of the pure nutrients, mixing the nitrogen, the phosphorus, the potassium, the selenium, the medium trace element fertilizer and the organic fertilizer; granulating, spraying the film coating agent and drying. An operation process is controllable, the utilization rate of the fertilizer is effectively improved, and the fertilizer effect is prolonged.

Description

technical field [0001] The invention relates to the field of fertilizers, and in particular to a fertilizer for Bletilla striata tuber expansion stage and a preparation method thereof. Background technique [0002] Bletilla striata, perennial herb, pseudobulb tuberous, white, thick, with finger-like divergences. It is commonly used for branch propagation and has excellent medicinal value. At present, the gap between the supply and demand of Bletilla striata is too large, resulting in a large amount of collection and consumption of wild plant resources, coupled with the further increase of forest coverage in hilly and mountainous areas in southern provinces, it also exacerbates the annual decline in the production of wild Bletilla striata, when the collection and consumption exceeds the natural When the regenerative ability of resources is reduced, it will inevitably lead to the endangerment or even extinction of species. Simultaneously along with the day by day destruction...

Problems solved by technology

At present, the gap between the supply and demand of Bletilla striata is too large, resulting in a large amount of collection and consumption of wild plant resources, coupled with the further increase of forest coverage in hilly and mountainous areas in southern provinces, it also exacerbates the annual decline in the production of wild Bletilla striata, when the collection and consumption exceeds the natural The regeneration ability of resources will inevitably lead to the endangerment or even extinction of species

At the same time, with the increasing destruction of the natural ecological environment, it has further led to the shortage of medicinal plant resources.

[0003] The main medicinal part of Bletilla striata is the tuber, but there are few Bletilla striata fertilizers on the market for the tuber expansion stage, and most of the compound fertilizer products on the market are general-purpose, that is, 17-17-17, 15-15-15, etc., no Specifically, according to the soil conditions, growth habits and fertilizer requirements of the bletilla striata, a special fertilizer formula for a specific period is launched, which lacks pertinence and cannot meet the nutrient needs of bletilla striata
