Fertilizer special for bletilla tissue culture seedling domestication for preventing and controlling underground insect attack, preparation method and application thereof

Abstract

The invention discloses a fertilizer special for bletilla tissue culture seedling domestication for preventing and controlling underground insect attack, a preparation method and an application thereof. The special fertilizer is prepared from the following raw materials in parts by weight: 10-20 parts of radix sophorae flavescentis, 20-30 parts of chinaberry seeds, 5-10 parts of potassium humate, 15-20 parts of oil tea cake, 1-5 parts of plant growth regulator, 80-120 parts of sheep manure, 100-150 parts of silkworm excrement and 5-10 parts of biological fermentation bacteria. According to the invention, the plant source insecticide material with high anti-insect capacity is added into the organic matter and growth promoter, including sheep manure, silkworm excrement and plant growth regulator, so that the quick growth of bletilla tissue culture seedling can be promoted, the domestication time is shortened and the underground insect attack can be effectively prevented and controlled in the bletilla tissue culture seedling domestication process; the base fertilizer is mixed and used with the plant source insecticide component, so that the dual effect of fertilizer and drug is achieved; the raw material source is wide, the preparation cost is low and the preparation method is simple; and after the fertilizer is applied to the bletilla tissue culture seedling domestication, the seedling percent of the bletilla tissue culture seedling domestication is greatly increased and the insect attack phenomenon caused by the bletilla rhizomes gnawed by the underground insects is basically eliminated.

Description

technical field [0001] The invention relates to a special fertilizer for the domestication of bletilla striata tissue culture seedlings for preventing and controlling underground insect pests, a preparation method and application thereof, and belongs to the technical field of bletilla striata fertilizers. Background technique [0002] Bletilla striata is a plant of the genus Bletilla striata in the family Orchidaceae, and its tubers are used as medicine. It has the functions of nourishing the lungs, stopping bleeding, reducing swelling and promoting muscle growth. Bletilla striata is one of the rare traditional Chinese medicinal materials in my country, and has a large market demand. Human over-harvesting and destruction of natural habitats have sharply reduced wild Bletilla striata resources and are on the verge of extinction. In order to protect wild resources and meet market demand, artificial planting of Bletilla striata has gradually emerged, but currently the cultivat...

AI Technical Summary

Problems solved by technology

In order to protect wild resources and meet market demand, the artificial planting of Bletilla striata is gradually rising, but at present, the cultivation of Bletilla striata is mainly based on division propagation, which has a low reproduction coefficient and poor benefits

In recent years, with the maturity of Bletilla striata tissue culture technology, large-scale and efficient planting of Bletilla striata has gradually formed. The characteristic of fertilization requires regular topdressing management. Under the conditions of loose domestication substrate, high humidity and high fertilizer, it is easy to breed underground pests, and it is difficult to detect, causing the rhizomes and young shoots of domesticated Bletilla striata to be gnawed, resulting in the growth of Bletilla striata seedlings. death, loss

[0003] Bletilla striata pests are mainly underground pests. Underground pests are the great enemies of Bletilla striata. They feed on pseudobulbs, young shoots, and rhizomes, causing seedling shortage and dead seedlings. Tigers, etc., because these underground pests harm the underground part of bletilla striata, they hide at daytime and come out at night, causing damage near the soil surface, and are difficult to be detected, so it is difficult to control

[0004] At present, the base fertilizer used for the domestication of Bletilla striata seedlings is mainly slow-release compound fertilizer. The fertilizer is not comprehensive in nutrition, and does not have the effect of preventing insect pests. The comprehensive application effect is not ideal, and there is still a lot of room for improvement.
