1. Do-it-yourself flowers grow in soil and need a lot of nutrients besides necessary temperature, light, air and water.

2. To master several methods of self-made fertilizer.

3. Put tea leaves, bean shells, melon peels, dregs, tea juice, pig, sheep and horse dung, weed urine, etc. These are readily available in daily life, put them in jars or jars and soak them in water.

4. The cylinder mouth is tightly sealed with plastic film, which is a good nitrogen-based fertilizer after 2-3 months of fermentation and decay.

5. Broken bean cake, rapeseed cake and tea seed cake. There is also stir-frying, which is put into a jar or bottle with deteriorated inedible soybeans and peanuts, soaked in water, sealed and allowed to ferment and rot.

6. Its juice is also a nitrogen-based fertilizer with high phosphorus and potassium content.

7. Pour fish scales, fish viscera, hair, chicken, duck and bird feathers, leftover fish, meat, crab bones and animal carcasses into a jar, add water to seal, ferment and rot, and when the juice turns black, it is a phosphorus-based fertilizer with high fertility.

8. In the process of making the above fertilizer, first, pay attention to the sealing of bottles, tanks and jars to prevent maggots and odor from overflowing.

9. Secondly, it should be noted that it can only be mixed with water after being fully fermented and decomposed into "cooked fertilizer". "Fattening" should not be used to water flowers immediately, especially precious flowers and trees such as camellia and azalea.

10 Third, according to the different growth stages of flowers and trees, the proportion of nitrogen and phosphorus should be properly balanced, especially when using phosphorus-based fertilizer, a certain proportion of nitrogen fertilizer must be added.

1 1. In addition, boiled water for washing fish and shrimp, foam floating on the surface when cooking broth, rice washing water, etc. It can be diluted with water and used as fertilizer for flowerpots.

12, these fertilizers are easily available, convenient and sanitary.

13. According to the types of flowers planted at home, it is more reasonable to use appropriate fertilizers. There are great differences in the amount of fertilizer required for different types of flowering periods, and there are also great differences in the concentration of nutrients in the body: (1) In terms of nitrogen and potassium, the contents of chrysanthemum, poinsettia, carnation, geranium and rose are much higher than those of azalea; The content of calcium is mostly chrysanthemum, carnation and poinsettia, while the content of rose, geranium and rhododendron is low. The content of magnesium in chrysanthemum and poinsettia is higher, but the content of magnesium in carnation, geranium, rhododendron and rose is lower. The boron contents in geranium and chrysanthemum are 0.003%-0.028% and 00025%-0.02% respectively, while those in rose, rhododendron, carnation and poinsettia are 0.003%-0.006%, 0.00 17-0.0 1% and poinsettia respectively.

14, (2) water-soluble flower fertilizer. There is good fertilizer for growing flowers. For example, many large flower planting bases now use some water-soluble fertilizers with high absorption rate and high utilization rate, such as molar water-soluble fertilizers. This is not blindly about absorption, mainly because the nutrients contained in it can supply the nutrients needed for flower growth, and the fertilization interval is only once every half month. Rational fertilization can prolong the flowering time of flowers.

15. In addition, kitchen leftovers, egg shells and fish bones can be directly buried in the pot soil. These things can provide nutrients for flowers. I hope they will help you.

16, the self-made fertilizer can be dug in a proper place, about 80 cm deep, the size should be adapted to local conditions, and the bottom of the pit is best paved with bricks; You can also put a large flowerpot on the balcony with 3 cm of fine sand or furnace ash at the bottom.

17. Crush the eggshells, meat scraps, poultry and fish's five viscera scales when fresh; You can also soak the broken bones of cooked meat in cold water 1 day, then wash, cook and mash them, then mix them with 30% sand or furnace ash, put them in into the pit or flower pots for flattening, cover the surface with a layer of pure land, sprinkle some pesticides, and cover them to keep them moist to promote the decomposition of fertilizers.
