There is no need to spend a lot of money on chemical fertilizers when families grow flowers. You can collect and make it yourself in your daily life. 1, nitrogen fertilizer (promoting lush foliage): such as hemp residue sauce, rotten bean curd, human urine, etc. 2. Phosphate fertilizer (promoting bright colors and fat fruits): such as minced meat and bones, fish bones, fish scales and rice washing water after fermentation with water. 3. Potassium fertilizer (promoting strong roots): such as plant ash. Self-made compound fertilizer water containing nitrogen, phosphorus and potassium can be brewed in spring, fully decomposed at high temperature in summer and diluted with clear water before application. The method is as follows: 1, fertilizer and water. Put broken bones, bean powder, rice washing water, hemp residue sauce, rotten vegetable leaves, etc. Put it in a vat filled with water, cover it, and put it in the sun to rot at high temperature. (Suitable for all potted flowers) 2. Alum water. In the above-mentioned soaked fat water, one or two ferrous sulfates are added for every ten catties. Suitable for flowers that like acidic soil, such as camellia, rhododendron, jasmine and gardenia. Note: When the above fertilizers are applied, they must be diluted with water! It is very important to grow flowers in limited pot soil. Nowadays, flowers and trees are fermented, and the fertilizer efficiency is long. Adding 1 to 2 times of water can be used as liquid fertilizer to improve broad bean shells, melon skins and so on. After decomposition, the above liquid was diluted with 9 times of water and used as liquid fertilizer. Suitable for sprouting branches and leaves in spring and peacetime. 2. Phosphate fertilizer: fish intestines, chicken and duck intestines, meat bones (no salt, to be broken), shrimp and crab shells, feathers, eggshells, etc. Adding 2-3 times of water, decomposing and diluting with 12 times of water, and using as liquid fertilizer. Rice washing water contains phosphate fertilizer, and it is best to add water to rice washing water. Suitable for plants before flowering. 3. Potash fertilizer: The above two fertilizers also contain potash fertilizer. If potassium fertilizer needs to be supplemented, 20% plant ash can be added to the pot soil, which can make the plants more robust and the roots more developed. 4. Long-acting full-effect fertilizers: soybeans, bean cakes, bean dregs, peanuts, rapeseed cakes, snails, shellfish, pigeons, chicken and duck manure, etc. Add 2-3 times of water, and then dilute it with 12 times of water as liquid fertilizer. It can also be dried, crushed and stored as base fertilizer. 5. Homemade culture soil: To make full use of the turned-over old soil, it is necessary to kill insects and disinfect. The old method is to bask in the sun for a few days, or spray medicine water. There is little soil in China, so you can put it in plastic bags according to the quantity, put it in the microwave oven, and open it with high-grade products for three to five minutes, so that the soil can be heated up quickly. When making culture soil, first spread a layer of old soil in the jar and put all kinds of food residues, melon and fruit skins, animal intestines and so on. Spread a layer of old soil on it, slightly compact it, pour some rice washing water, then spread it with various scraps, and add a layer of old soil. After three to six months of decomposition, turn it over and stir it evenly, and let it dry slowly. The residue left by liquid fertilizer in the early stage can also be mixed into the culture soil for utilization. The above-mentioned fertilizer will have an odor and easily breed insects such as flies, so it is best to put it in a covered container, cover the big jar with plastic film, then tie it tightly with a rope, and put chopped orange peel into it after decomposition to improve the odor. After years of practice, I have some simple fertilization methods for reference: 1 Usually, don't pour the water from cook the meat, chickens and ducks (without salt) and put it in a beverage bottle. After two months, add three to four times of water as liquid fertilizer, which is the best fertilization for pomegranate. Second, the skin left after eating watermelon in summer can be cut into small squares, directly buried in the soil around the basin (without direct contact with the roots of plants), and watered normally. After five to seven days, it will turn into fertilizer water and penetrate into the soil to see the fertilizer effect, with no odor and no moth. It is most suitable for planting foliage plants, and can be used once every ten days without fertilizer damage. 3. put the orange peel in the refrigerator to remove the odor and make it into dried tangerine peel. When in use, it is divided into small pieces. Dig loose the topsoil around the pot, insert the dried orange peel along the edge of the pot, cover it with soil, water it normally, and gradually rot into a fertilizer without odor and moth. All plants need fertilizer for growth, flowering and fruiting, so they need continuous supply. It is advisable to apply liquid fertilizer once every ten days. In order to prevent fertilizer damage, fertilizer should be decomposed, diluted rather than concentrated, but not applied in full bloom to prevent flowers from falling early. 9. In 10, a long-acting full-effect organic solid fertilizer should be applied to woody potted plants before hibernation in winter, and buried in the topsoil shallowly to lay a good foundation for the growth of the next year. Never pour milk and soybean milk into the pot soil before it decomposes, and don't pour the eggshell upside down on the pot soil, thinking that the leftover liquid can be used as fertilizer, which will produce small black flying insects, which is very unsanitary and unfavorable to the pot flowers.
