Requirements for moisture of flowers and preservation methods of edible fungi

1. Irrigation-The watering of potted and greenhouse flowers and open field flowers should be carried out according to the type of flower, growth stage and soil moisture content. Generally herbaceous flowers grow best when the soil moisture content is 15%, and when it is lower than this index, irrigation should be applied. In the flower seedling stage, growth and development exuberant, water demand more, not timely watering will occur wilting, adverse to the growth of young chrysanthemum. The flowering period should be watered properly, while the dormant period and the fruiting period should be watered less. If the soil is too dry or wet during transplantation and planting, it will affect the growth of young roots and new roots, and then affect survival.

2. Drainage-If the pot soil is too wet, the air in the pot soil will be relatively reduced, thus affecting the respiration of the roots and the absorption of water and nutrients. At the same time, the activity of anaerobic bacteria will increase, resulting in toxic gases poisoning the roots. Therefore, both potted flowers and flowers cultivated in the open field should pay attention to drainage. The drainage method of potted flowers is: the bottom hole of the flowerpot should be stacked with 2 small tiles, so that the bottom hole of the flowerpot has a larger pore, and then a layer of broken bricks and stones (filled in the bottom of the flowerpot about 1 cm thick) are scattered on it. Finally, a certain proportion of sand should be put into the culture soil when planting flowers. After the flowerpot laid with drainage layer, the bottom hole is dredged, and excess water in the pot soil can be removed in time.

3. Spray and ventilation-Flowers native to tropical and subtropical rainforests require not only moist soil but also high air humidity. Such as the cultivation of tropical orchids leaf flowers should often spray water to the leaves and the ground, so that the surrounding air humidity can be larger, which is conducive to the growth and development of tropical orchids. However, if the humidity is too large, some flowers are prone to aphids and powdery mildew, and measures should be taken immediately to ventilate and reduce the ambient humidity.
