(1) organic fertilizer. It is usually divided into animal organic fertilizer and plant organic fertilizer. Animal organic fertilizer includes human excrement and urine, feather, hoof angle and bone powder of livestock, waste of fish, meat and eggs, etc. Plant organic fertilizer includes bean cake and other cake fertilizer, sesame paste residue, weeds, leaves, green manure, Chinese herbal medicine residue, distiller's grains, etc. These two kinds of fertilizers are slow effect fertilizers, with complete nutrients and long fertilizer effect. They can be used only after fermentation and maturity.
(2) inorganic fertilizer. It is a kind of fertilizer rich in mineral nutrients which is made by chemical synthesis or natural ore processing. For example, nitrogen fertilizer includes urea, ammonium sulfate, ammonium chloride, ammonium nitrate, etc. Phosphate fertilizer includes superphosphate, phosphate rock powder, etc. Potassium fertilizer includes potassium chloride, potassium sulfate, etc. Fertilizer is fast in fertilizer efficiency, but simple in fertilizer content; it is violent in nature, but not lasting. Except for phosphorus fertilizer, general fertilizer is used for top dressing.
In daily life, there are many wastes that can be used to make fertilizer:
(1) soak liquid fertilizer. Use small jars (or jars) to put waste vegetable leaves, melon and fruit skins, chickens and fish into the water, fish scales, bones, eggshells and moldy food (peanuts, melon seeds, beans, bean powder *), add water and sprinkle a little trichlorfon on the back cover. After high-temperature fermentation and maturity, it can be used. When using, take the supernatant and dilute it with water before application. The waste can be mixed with some old culture soil, added with some water, put into a large plastic bag, tightly placed for a period of time, and used after fermentation.
(2) waste composting. Dig a soil pit in a proper place with a depth of 60cm-80cm and a layer of 10cm ash. Put the rotten vegetable leaves, internal organs of livestock, fish scales, chicken and duck dung, eggshells, meat wastes and broken bones into the pit, spray some insecticides, cover the pit with a layer of 10cm thick Garden soil, keep the pit moist, so as to promote the maturity of fertilizer. It's best to pile it up in autumn and winter. When it's heated up and ripened in spring and free of odor, it can be mixed into the culture soil as the base fertilizer. It can also be used as the 4mm sieve when it's wet and sieved to form the pellets, the fine as the top fertilizer and the coarse as the base fertilizer.
