花卉培养土介质（Flower culture; soil media）
花卉培养土介质（Flower culture; soil media） First, the commonly used soilless media A: the use of bagasse in the tropics, with a high ratio of carbon to nitrogen, nitrogen must be added, to meet the needs of rapid microbial decomposition. Bagasse has very high water holding capacity. It decomposes rapidly in the container, is easy to compact and causes poor ventilation and drainage. Therefore, it is seldom used in potting medium. After composting of bagasse, mixed with field soil, especially for clay, can play a role in the improvement. The bark of pine bark and hardwood bark, has good physical properties, can replace peat as potting medium. The main problem of fresh bark is that carbon and nitrogen are relatively high. Some bark, such as bark, contain toxic components of plants and should be degraded by composting or leaching. The bark must be crushed first, and the diameter of the particles can be as large as 1cm, and the average diameter is 1.5 to 6mm. The particle size is screened, and small particles can be used as soil amendments in the field. Coarse particles are best used as potting media. When the hardwood bark is decomposed, the requirement of nitrogen is between 1.1 and 1.4%, and the requirement of cork bark is between 0.3 and 1.3%. After adding nitrogen and water treatment, at least for more than 2 months, during which there are several times after the pile can be used. Some flowers are planted in 100% pine bark, peat and sand saddle volume ratio of 1:1, peat and perlite (l:1), the effect is the same, and even better with pine bark. Usually used as a potting medium, the amount is 25% to 75% of the total volume, because excessive ventilation is harmful to watering and fertilization. Hardwood bark is reported as a potting medium, It can inhibit the occurrence of plant parasitic nematodes and soil pathogenic bacteria. As a soil amendment, 5cm thick bark is added to 150 kg of nitrogen per hectare, mixed with 15 to 20cm deep layers. The wood sawdust and bark have sim
