Experience of returning tissue culture hybrid grass culture

Because tissue culture hybrid many high-grade orchids are getting closer and closer to our real orchid friends, it is no longer an unreachable dream for ordinary orchid friends, and it is very responsible to say that the price of Huilan will certainly follow the old path of Chunlan. There will also be more classic artificial hybrids, more tissue culture varieties, tissue culture technology is not high-tech, do not need a particularly complex laboratory to produce. Since the face of a number of resale grass, tissue culture grass, hybrid grass, we should also improve the breeding technology, to introduce my breeding methods.

1, disinfection and sterilization, after the grass is bought, first wash it with tap water, soak it in chlorothalonil solution for 10 to 15 minutes, and then take it out to dry for more than 10 hours. 2, material ratio, burning soil, plant stone, peat, lotus king fairy soil, rotten chestnut leaves, snake wood, all kinds of material proportion is the same. 3, the grass root is stuffed into the stone, let the root open, planted in the basin, the root water must be fixed. 4, after survival or to bask in the sun, to appropriate shade, basin slow application of 20 grains of fertilizer, away from the root, once every 3 months. Play carbendazim once every 3 months without stagnant water on the leaves. It can also be used intermittently. 6, after rejuvenation, you can use fertilizer with high phosphorus and potassium content to make it blossom.

Properties and uses of charcoal soil Peat is also known as peat and meadow soil. It is a loose accumulation or mineralized rotten plant composed of swamp plant remains, and it contains a lot of organic matter. First, the type of peat. Low peat is a substance formed under the conditions of stagnant water and mineral-rich underground water sources. peat plants are rich in nutrients, and the contents of ash, nutrients and humic acid in peat are also high. It is characterized by high nitrogen nutrients and mineral elements, low acidity, slightly acidic to neutral reaction, and high degree of decomposition. two。 The middle and high peat is in the upper layer of slightly higher topography or low peat protruding, and is composed of marsh plant residues with lower nutritional requirements, such as lotus grass, mosses and so on. It is mainly mineralized by Rain Water with low mineral content as water source. It is characterized by moderate nitrogen nutrients and mineral elements, high acidity and poor decomposition in acidic or strong acid reaction. Peat can be used as soil improver to produce biological fertilizer, organic fertilizer, compound fertilizer and plant hormone. The application of peat in agricultural production can improve soil, increase the content of nitrogen, phosphorus and potassium, increase the total amount of organic matter and humic acid, activate soil fertility, and improve crop quality and yield. 2. It can be used to prepare all kinds of nutritious soil and flower soil. All kinds of nutritious soil and flower soil prepared with peat as the main raw material can be used for the cultivation of industrial vegetables, flowers, high-grade flowers, potted flowers and soilless cultivation. All kinds of nutritious soil and flower soil prepared with peat (peat) as the main raw material can make the fertility sufficient, the fertilizer effect long, reduce the production of diseases and insect pests and peculiar smell, improve the rot resistance and stress resistance of crops, promote plant growth, and make the leaves of flowers dark green, flowers big and colorful, florescence prolonged and so on. 3. The use of peat to build lawn, golf, football field and other places can make the lawn grow strong, conserve water and fertilizer, and prevent dryness.
