The preparation method of flower culture soil and how to make rotten leaf culture soil

General flowers and plants prefer sandy loam with organic matter and good permeability, and generally require moderate acidity and basicity. This kind of soil does not exist too much in nature, which is difficult to find. Therefore, if you want to raise flowers well, you generally need to artificially prepare the culture soil.

The preparation method of rotten leaf culture soil, rotten leaf culture soil is one of the most commonly used in our country. In autumn, we can use deciduous leaves of broad-leaved trees, stems and leaves of herbaceous plants, sawdust and horse dung to make rotten leaf culture soil. The general proportion is 50% of deciduous leaves of broad-leaved trees, 30% of sawdust, 20% of horse manure, layered accumulation, and then covered with 10 cm thick pastoral soil. To ferment and rot. When piling up, you can press the east-west direction, 1 meter high and 1 meter wide, length according to local conditions, and pour clear water with the pile. If horse dung is not found, you can also use leaves and sawdust in half, but then you need to sprinkle with thin human feces or hogwash. Similarly, you can also dig 1 meter deep fertilizer pool retting system.

In the spring of the following year, turn and smash the rotten leaves, and then according to the volume ratio, use rotten leaves to compost 40% of the soil, 40% of the plain sandy soil, and 20% of the furnace ash soil; mix it evenly, pile it for a period of time, pay attention to keep it moist, and turn it as many times as possible, so that the fertilizer is fully mixed with the soil, and it can be used.

The preparation method of peat culture soil is as follows: peat soil 40%, plain sandy soil 40%, horse dung or rotten leaf compost 20%, mixed and stacked evenly, keep it moist, and can also throw thin human feces and urine when there is no horse dung. It can be used after full fermentation.

The preparation method of natural humus culture soil: according to the content and dispersion degree of humus in mountain humus soil, mixed with roadside accumulation soil or river mud and thin human feces and urine, and then stacked for a period of time, when it is fully fermented and mature, it can be used.

The stacking time of all kinds of culture soil can be used in the same year, while delicate flowers or cutting soil need to be used every other year.

In general, before the use of culture soil, we need to use a sieve to sift into aggregates while wet, and some need to be mixed with an appropriate amount of germicidal pesticides.
