Water Requirements of Flowers and Preservation Methods of Edible Fungi

1. Watering - Watering for potted flowers, greenhouse-cultivated flowers and open-field flowers should be carried out according to the flower species, growth stage and soil moisture content. Generally, herbaceous flowers grow best when the soil moisture content is 15%; when it falls below this level, watering should be done. During the seedling stage, flowers grow vigorously and need more water; if not watered in time, they will wilt, which is unfavorable to the growth of young chrysanthemums. During the flowering period, water should be given timely and in appropriate amounts, while during the dormant period and seed-setting period, less water should be given. During transplanting and planting out, if the soil is too dry or too wet, it will affect the growth of young roots and new roots, and further affect the survival rate.

2. Drainage - If the potting soil is too wet, the air in the potting soil will be relatively reduced, thus affecting the respiration of the root system and the absorption of water and nutrients; at the same time, the activity of anaerobic bacteria increases, producing toxic gases that harm the root system. Therefore, whether for potted flowers or open-field cultivated flowers, attention must be paid to drainage. The drainage method for potted flowers is: the bottom hole of the flower pot should be covered with 2 small tile pieces placed overlapping each other in a staggered way, so that there is a relatively large gap at the bottom hole of the pot; then spread a layer of broken bricks and gravel on top (filled about 1 cm thick at the bottom of the pot); finally, when planting the flowers, the culture soil should also contain a certain proportion of sand. In pots laid with a drainage layer, the bottom hole is kept unobstructed, so excess water in the potting soil can be drained away in time.

3. Misting and ventilation - Flowers native to tropical and subtropical rainforests require not only moist soil but also relatively high air humidity. For example, when cultivating foliage flowers such as tropical orchids, water should often be sprayed on the leaves and ground, which can make the surrounding air humidity higher and is beneficial to the growth and development of tropical orchids. However, if the humidity is too high, some flowers are prone to aphids and powdery mildew; at this time, measures should be taken immediately to ventilate and exchange air so as to bring the environmental humidity down.
