It has good hydrophobic performance, neutral pH value, clean and sterile, nutrient free, low fertilizer and water retention.
Slight acid, clean and sterile, moderate fertilizer and water conservation.
Micro acid, organic matter, fertilizer and water conservation.
The above three planting materials can meet the needs of violet if they are compounded according to a certain proportion. The way of water supply by line suction is used, so the hydrophobicity needs to be especially improved.
Perlite: vermiculite: peat soil (2:1:1). The proportion of vermiculite and peat soil can be increased properly by normal watering. Of course, these proportions are not necessary. Adjust the proportions according to the planting environment and Angshi. If the environment is high humidity or watering frequently, the hydrophobicity will be improved, otherwise the water retention will be improved.
When the pH value is lower than 6.5, it will produce chemical lock effect, which will make the plant unable to absorb the nutrients in the plant, only iron can be absorbed. A single iron element will cause toxicity in the plant, and the plant will die with the accumulation of toxin. Therefore, it is a good choice to change the plant material once a half year or so.
It contains calcium, which can delay the acid change of the plant material and prolong the use time of the plant material.
Regulate humidity, filter impurities, deodorize, decompose harmful chemicals, provide trace elements, and delay the acid change of plant materials.
After adding some auxiliary materials, the soil replacement time can be extended for 2-3 months. It can also be judged whether the plant material is sour by the growth form of the plant. After 6-9 months of using the plant material, there is still no time to change the soil, so it is necessary to apply less fertilizer or even no fertilizer, and wash the plant material with water from time to time, which is also a way to alleviate the acid change of the plant material.
