The formula of raising orchids with pine needles

In the process of raising orchids with pine needles, 5 parts of pine needle soil, 3 parts of yellow sand soil and 2 parts of river sand can be mixed to make culture soil, or it can be made from humus soil, 2 parts of pine needle soil and 2 parts of river sand. It needs to be thoroughly sterilized before going on the basin, or it can be made by mixing humus soil, pine needle, perlite or volcanic stone.

Formula for raising orchids with pine needles

Pine needle soil has good water retention and air permeability, which is more suitable for the growth of orchids. Generally, 5 parts of pine needle soil, 3 parts of yellow sand and 2 parts of river sand can be used to make culture soil, which is more loose, permeable and nutritious. Among them, the river sand has good drainage, which can promote the root growth of orchids.

Some rotten leaf soil can also be added to the pine needle soil. 3 parts of rotten leaf soil, 2 parts of pine needle soil and 2 parts of river sand can be mixed to make culture soil. The rotten leaf soil is mainly made of rotten leaves or mature grass. The soil needs to be thoroughly disinfected before the basin, so that there are germs in the soil, which is disadvantageous to growth.

In addition, the field is also the best mixed plant material, you can add some small stones to the bottom of the basin, cover a layer of field soil, then cover the surface of the basin soil with pine needle soil, and add some mature compost or fermented bean cake, peanut shell and other organic fertilizer. stir and mix evenly before the basin, so that the distribution of nutrients can be more balanced.

When using pine needles to cultivate orchids, do not all use pine needles, which can not guarantee the comprehensiveness of nutrition. You can put some humus soil at the bottom of the basin when you go up the basin, and put an appropriate amount of pine needles and river sand in the upper part. Some volcanic rocks or perlite can also be added appropriately to ensure adequate nutrient demand.
