Specially-made fertilizer for culturing dendrobium candidum wall.ex lindl, and preparation method thereof

Abstract

The present invention relates to specially-made fertilizer for culturing dendrobium candidum wall.ex lindl, and a preparation method thereof, and belongs to the technical field of organic fertilizer. According to the present invention, the specially-made cultivation fertilizer suitable for the dendrobium candidum wall.ex lindl growth is developed according to the wild natural environment of the dendrobium candidum wall.ex lindl and the characteristic of endomycorrhiza of the dendrobium candidum wall.ex lindl; the formula of the specially-made fertilizer comprises tea bran, fish meal, bone meal, a small amount of phosphorus fertilizer and 100 parts by weight of water, wherein a ratio of the tea bran to the fish meal to the bone meal is 2-4:4-8:4-8. The preparation method comprises: concurrently pouring various components in a plastic bucket according to the ratio, uniformly mixing, fermenting for 3-6 months, and collecting supernatant after fermenting and ripening to obtain the specially-made fertilizer. With the present invention, the difficulties of low transplant survival rate of the dendrobium candidum wall.ex lindl seedlings, slow growth, not high yield and high cultivation cost are solved, such that the transplant survival rate of the dendrobium candidum wall.ex lindl seedlings is more than 98%, the dendrobium candidum wall.ex lindl flowers or produces stems and leaves 1-3 years in advance, the yield is high (the yield per mu is more than 250 kg), the active ingredient content is high, and the quality is excellent; the technical assurance is provided for rapidly culturing the dendrobium candidum wall.ex lindl; the active promotion effects are provided for development, utilization, and meeting of living requirements of the dendrobium candidum wall.ex lindl; important social benefits and economic benefits are provided.
