It refers to the fertile soil in the vegetable garden or garden which has been improved, fertilized and well cultivated. It is a kind of micro acid soil which has been broken and screened, and has removed the miscellaneous grass roots and broken stones without insect eggs.
It is a rotten leaf soil composed of litter and rotten roots. It has rich humus and good physical properties, is conducive to fertilizer conservation and drainage, and the soil is loose. Acidic. It can also pile up fallen leaves and be fermented and decomposed.
The formation of cultivated land is to pile up a layer of grass, dead leaves, broken branches and a layer of common garden soil, pour in rotten cake fertilizer, let it ferment and ripen, and then break it up and sift.
In ancient times, the plants in the limnetic zone were buried in the ground. Under the conditions of flooding and lack of air, they were decomposed into incomplete special organics. Peat soil is rich in organic matter and difficult to decompose.
It is mainly 2-3 mm diameter sand particles, which are neutral. The coarse sand does not contain any nutrients and has the function of aeration and water permeability.
It is a kind of thick and long plant material with strong tensile resistance, which has the advantages of looseness, permeability and moisture retention.
It is a mica like material formed by heating silicate material at 800-1100 ℃, with good ventilation, large porosity and strong water holding capacity. However, it is easy to be dense after long-term use, which affects the ventilation and drainage effect.
It is a natural Al Si compound, an expansion material formed by heating the crushed magmatic rock to over 1000 ℃, with a closed porous structure. The material is light and the ventilation is good.
General category: fertile garden soil, peat soil, coarse sand, perlite 1.
Raw stone flowers: 1 part of fine garden soil, 1 part of coarse sand, 1 part of coconut bran, a little of rice bran ash.
Fine roots: 6 peat soil, 2 perlite, 2 coarse sand.
Succulent plants with slow growth and fleshy roots: 6 parts of coarse sand, 1 part of vermiculite, 2 parts of granular soil and 1 part of peat soil.
Euphorbiaceae: peat soil 2, vermiculite 1, fertile garden soil 2, fine gravel 3.
Small leaves: 2 parts of rotten leaf soil, 2 parts of coarse sand, 1 part of husk carbon.
Stem dry: 2 parts of rotten leaf soil, 2 parts of coarse sand, 1 part of loam, 1 part of chaff and 1 part of broken brick slag.
Spherical strong spines: mixed soil with fertile garden soil, rotten leaf soil, coarse sand and a small amount of bone meal and dry cow dung.
Epiphytic cactus: mixed soil with rotten leaf soil or peat soil, coarse sand and a small amount of bone powder.
Cactus: a mixture of cultivated soil, coarse sand, and a small amount of bone meal.
Half of the succulent plants like 1:1:1:1 garden soil, peat soil, coarse sand and perlite mixed soil. This kind of mixed soil contains certain humus and has good drainage performance, which is suitable for the growth requirements of most succulent plants.
The slow growing succulent plants with fleshy roots do not have high requirements for humus, but they need good ventilation and drainage. Therefore, the mixture of coarse sand, vermiculite, granular soil and peat soil with a ratio of 6:1:2:1 is the most suitable.
The potted soil of succulent plants is generally required to be loose and permeable, with proper humus content in drainage, and neutral soil is suitable. A small number of succulent plants, such as Huwei orchid, Adenium obesum, Senecio, Aralia and twelve rolls, need slightly alkaline soil, while Armeniaca likes alkaline soil. All cultivated soil should be strictly disinfected before use. When using, spray water on the cultivated soil, mix evenly, adjust the soil humidity and then put it into the basin.
