What is the effect of sawdust for growing flowers.

Sawdust has comprehensive nutrition, loose texture, water retention and ventilation, cleanliness and hygiene. The methods of sawdust for cultivation of flowers are summarized as follows.

1. Sawdust can be used as a substrate for bandaging high branches of flowers and trees, such as rhododendron, kumquat, camellia, sweet-scented osmanthus and so on. The method is: in the plum rain season, select the vigorous branches of last year, peel them in a ring at 10mur15cm from the top, wrap them in a plastic bag, fill the bags with wet sawdust and mountain mud (mixed with each other), tie them tightly at both ends, and then put the potted flowers in a half-shady and half-sunny place for daily maintenance and management. 2Mel-3 months can take root, and after taking root, it can be cut off from the mother plant to form a new flower seedling.

2. Sawdust can be used as the rooting medium for flower cuttings such as rose, gardenia, pomegranate and so on. The method is as follows: a plastic film with a certain length, which is slightly higher than the height of the cutter, is covered with wet sawdust (hand-pinched without dripping), and then the cutter is covered with wet sawdust at a distance of about 3cm, and then the top of the cutter is covered with wet sawdust. Finally, it is rolled up and fastened, with 20 inserts for every 10mur. each bundle is packed in a large plastic film bag, and the mouth of the bag is slightly fastened to facilitate heat preservation. Because the humidity is easy to control, it takes root faster.

3. Mix sawdust with human feces and urine, pack it in a plastic bag, tighten the mouth of the bag, put it at the temperature of 30 ℃, and ferment and rot in 1 Mel-2 months. Then hang it to semi-dry, mix with the soil, and use it as potted soil to cultivate flowers and trees, which can grow branches, leaves and green, flowers with rich fragrance; using it as a nutritive soil for flower seedlings has the wonderful function of promoting the healthy growth of flowers and seedlings.

4. The sawdust after fermentation rot has comprehensive nutrition, no risk of nitrogen deficiency, phosphorus and potassium deficiency, loose texture, moderate dry and wet, so it is a simple and convenient soilless cultivation material, especially suitable for potted asparagus, orchid and so on. Putting this potted flower indoors, it is not only clean and hygienic, but also elegant and elegant, which is an ideal ornament.

5. After fermentation and disinfection, the sawdust can be used as the substrate for transitional cultivation of test-tube plantlets after adjusting the pH, and its effect is as good as perlite powder.

Sawdust not only has many uses in industrial and agricultural production, but also has many wonderful uses in flower cultivation. I don't know how much you've learned.

Sawdust is a cheap soilless culture substrate. if there is sawdust around the flower planting, sawdust can be turned into a good soilless culture substrate by the following methods.

New sawdust shipped from the factory should first understand the source of sawdust. If it is wood from sea transportation, it may contain excessive sea salt. It is best not to use this sawdust. If necessary, wash the salt with water so that its concentration is below 10mm / L.

To confirm the non-toxic sawdust, it is best to choose sheltered and sunny ground for one year, so that it has enough time to ferment until the sawdust color is lighter and darker. Then turn the sun several times in the hot sun and disinfect it with sunlight exposure. The sterilized sawdust should no longer be caught in the rain or contaminated by dirt and can be used in a basin at any time.

Features:

1: light

Sawdust matrix is very light, which is similar to the bulk density of perlite and vermiculite. Growing flowers as a long-distance transportation or high-rise building is a good substrate.

2: absorb water and breathe

Sawdust has good water absorption and permeability, and it is agreed to meet the proportion of moisture for most plants with strong roots, and for plants with slender roots, in the south or coastal cities with high air humidity, the proportion of moisture in sawdust is also very suitable. In the dry areas of the north, due to the good permeability of sawdust, the root system is easy to dry, resulting in plant death, sawdust is best used in these areas to use peat to form a mixed substrate.

3: the chemical composition of some tree species is harmful

The sawdust of most pine and cypress plants contains harmful substances such as resin and turpentine, and the ratio of carbon to nitrogen is very high, which is disadvantageous to plant growth. But the sawdust of shirt wood is very good, such as spruce and fir.
