First of all, prepare a few pots with a diameter of one and a half to two feet (depending on the amount required), cut a piece of gauze that is not used at home and put it in the flower pot, this function is because there will be a hole at the bottom of the flower pot, in order to prevent the soil from leaking out, put a piece of gauze first; Next, spread a layer of soil about 1 inch thick on the bottom; The third step is to cut the leaves and peels, put them in the pot and cover them with a layer of soil, and repeat this step until the whole pot is full; The last step is to sprinkle some water on the top soil, the water must be taken appropriately, not too much or too little, if the peel is more watery, such as: watermelon, put less water.
After three months, the finished soil is stirred to create a pot of new soil full of nutrients. It should be emphasized that in addition to cutting the leaves or peels that you want to put into the culture soil, you must wait until they are collected enough to cover the layer before putting them in the pot, and the peels that are put into the first layer should be covered with another layer of soil, which is to avoid mosquitoes, insects or bad smells.
soil disinfection
Whether disinfection is required
Generally, the culture soil of potted plants does not need special disinfection, as long as it is exposed to sunlight. This is because, on the one hand, flowers themselves have a certain resistance; On the other hand, the soil contains a large number of microorganisms, and their activities successively decompose many nutrients to maintain soil fertility and facilitate the growth of flowers and trees. It can also be disinfected with high temperature or chemicals, but the microorganisms are killed, and the organic matter in the soil cannot be decomposed, which is not conducive to the absorption of flowers and trees. The culture soil used for cuttings and sowing should be strictly disinfected, because the germs are easy to invade the body of flowers and trees from the cuttings wound, causing rot and affecting survival.
Commonly used disinfection methods
Commonly used soil disinfection method: The cooking disinfection method is to put the prepared culture soil into an appropriate container and cook and disinfect for 30 minutes. The pharmaceutical disinfection method is mainly disinfected with formalin. Sprinkle 40% formalin solution evenly with 4 ml to 5 ml per liter of culture soil and seal it so that it does not leak. Leave for 2 days before opening.
PH
Effect of soil pH on flowers
Soil pH is expressed as pH. pH value < 5.0 is strongly acidic, pH value 5.0~6.5 is acidic, pH value 6.5~7.5 is neutral, pH value 7.5~8.5 is alkaline, pH value >8.5 is strongly alkaline. If the soil pH is not suitable, it will hinder the absorption of nutrients by plants, because the pH is related to the solubility of mineral salts. The availability of nitrogen, phosphorus, potassium, sulfur, calcium, magnesium, iron, manganese, molybdenum, boron, copper, zinc, etc. in mineral nutrients varies with the acidity and alkalinity of soil solution.
Determination of soil pH: take a small amount of culture soil, put it in a glass, add water according to the ratio of soil: water = 1 : 2, stir fully, dip litmus test paper or extensive pH test paper into the clarification solution, and know its pH according to the change of the color of the test paper.
Adjustment of soil pH: When the acid is too high, some lime powder can be mixed into the culture soil or the proportion of plant ash (chaff ash can also be increased). When the alkalinity is too high, an appropriate amount of aluminum sulfate (alum), ferrous sulfate (alum) or sulfur powder can be added. The use of ammonium sulfate when applying nitrogen fertilizer can also reduce soil alkalinity and increase acidity. The alkaline potting soil can also be neutralized with the peel of the fruit, and the apple peel and apple core can be soaked in cold water, and the alkalinity of the potting soil can be gradually reduced by watering with this water.
