Can the branches and leaves of fir trees picked up under the rural fir forest be used as humus soil?

Personally, I don't think so, conifers.

The leaves are not perishable, have low nutritional value, and also contain many toxic secondary metabolites that can make the soil strongly acidic. To make humus, it is advisable to use broad-leaved trees that are easy to decompose, such as oak, sweetgum, and legumes.

Trees, alders. Wait. Lauraceae species such as camphor are also not suitable because they contain a lot of camphor.

and other substances, which also have a certain inhibitory effect on plant growth. The inhibition and acidity of conifers, camphor and other tree species can be neutralized by adding lime during decomposition.

During the vigorous growth period, it is necessary to top pruning fertilizer, generally once, and pay attention to loosening the soil and weeding. Weeding and loosening soil is the removal of weeds and vines.

Loosen the soil, enhance air permeability, improve physical and chemical properties, create a comfortable and good soil environment space, improve the life function of the root system, promote its robust and rapid growth, and lay a solid foundation for the high yield and high efficiency of Metasequoia. Grass is loosened twice a year, and the best tending effect is in May-June and August-September in the early stage of metasequoia growth. Moderate intercropping is to make full use of forest clearing, improve land utilization, improve soil structure, and enhance soil fertility.

Within 1-2 years of afforestation, appropriate interplanting of legume crops or green manure can be carried out. In order not to affect the growth of the sapling, intercropping crops should be kept at a distance of 30-40 cm from the sapling. Depending on where you live, choose to collect different kinds of fallen leaves.

You can collect all kinds of hay, straw or fallen leaves, and you can also prepare some garden soil. If you have a small yard at home, you can directly dig a deep pit, about 1 meter long, and dig the long trench. Then the collected branches are spread at the bottom, spread at the bottom, and then put them in the order of layer by layer of fallen leaves and layer by layer of soil.

The middle spacer can hold some eggshells.

Vegetable leaves or food waste.

After repeated accumulation, water is added appropriately, and finally burial is not managed. After half a year to a year, excellent humus can be obtained. Generally, there are patches of woods around the neighborhood where we live.

Trees shed leaves throughout the year, and after accumulating over a long period of time, they decay under the tree along with the soil, and finally become rotting leaves, which is called humus soil.

The effect of fir leaves as humus soil is not good, one is that fir leaves are not easy to rot, and the other is that the fertilizer is not high.

The leaves of the cedar tree can be used as humus. Usually in the woods or under the haystacks or under the pine trees in the park, there is some brown soil. This soil is actually the best soil for oxidation, and it is a soil rich in organic matter formed by the fermentation of leaves over a long period of time.

I think of course it is, and this kind of soil plant will be very good and will not need to use other fertilizers.

I think of course you can, but you have to expose yourself to the sun or blanch it with hot water to sterilize and kill insects before you can use it for planting.
