Problems solved by technology

In the general production process, people often mix a variety of substrates and then apply appropriate amount of nitrogen and phosphorus fertilizers as plant medium. Although it can provide the nutrients needed by plants, the ratio is rough, the use efficiency is low, the survival rate is low, and the growth is slow. And it is not suitable for the cultivation of most plants. For example, if ordinary substrates are used for cutting cultivation of Podocarpus spikes, it takes up to 90 days for rooting

Abstract

The invention discloses a podocarpus macrophyllus culture medium and a preparation method thereof, and belongs to the technical field of plant tissue culture. The podocarpus macrophyllus culture medium comprises, by weight, 25-40 parts of vermiculite, 30-50 parts of bagasse, 55-75 parts of weathered coal, 20-45 parts of plant ash, 60-80 parts of straw, 2-5 parts of plant growth regulator, 30-50 parts of fermented animal dung, 10-15 parts of calcium superphosphate and 90-100 parts of peat. The preparation method comprises the steps of raw material treatment, mixing, spraying and disinfection. The podocarpus macrophyllus culture medium is reasonable in matching, balanced in nutrition, suitable for growth of podocarpus macrophyllus and capable of promoting growth of podocarpus macrophyllus rapidly. The preparation method is simple, high in feasibility and capable of effectively increasing the survival rate of podocarpus macrophyllus cultivation.

Description

technical field [0001] The invention relates to the technical field of plant tissue culture, in particular to a podocarpus culture medium and a preparation method thereof. Background technique [0002] Podocarpus, also known as Tushan, belongs to Podocarpus family and Podocarpus genus. Podocarpus is an evergreen tree, with spiral-shaped alternate leaves, strip-lanceolate, prominent midribs on both sides, and dioecious plants. Podocarpus is a subtropical tree species native to Yunnan. It likes moist and well-drained sandy loam. Its tree is negative and has weak cold resistance. It has the strongest resistance to harmful gases among pine, cypress and fir. [0003] At present, with the development of society, the human demand for plants is gradually increasing. The main uses of plants can be summarized as wood, medicine, spices, carving crafts, etc., but they are often limited by the external environment, and their growth rate is slow. It is difficult for their growth rate to...
