Know how to cultivate edible fungi and water flowers skillfully in summer and autumn

Flowers can generally be divided into three categories: first, positive plants, such as jasmine, rose, plum, begonia, pomegranate, etc., which are resistant to drought and sun; second, negative plants, such as orchids, asparagus, evergreen, calamus, four seasons begonia, etc., they are resistant to dampness and shade, afraid of drying. Third, semi-negative plants, such as camellia, rhododendron, Magnolia, Milan and so on, they are resistant to dampness and like the sun. According to its plant characteristics, the important link of watering flowers should be emphasized in summer and autumn.

First, water the flowers in summer.

Summer is the season when most potted flowers grow vigorously, with large evaporation, which should be watered properly. Indoor flowers should be watered once every 3 days, and outdoor plants should be watered once a day. Different varieties of flowers should be treated differently. In general, herbaceous flowers need more water than woody flowers and should be watered more. For positive plants, adequate sunlight should be placed, watering should be sufficient, and there should be no stagnant water in the basin; for semi-negative plants, such as camellias and azaleas, it is better to put them in half-shade and half-sun, and it is better to be ventilated; the foliage plants should be shaded. Into the growth slow period or semi-dormant state of crab claw orchid, four seasons crabapple and other flowers pot soil should be dry, flowering flowers should also be less watered, so as not to knock down buds. Do not apply fertilizer or apply light fertilizer and water in hot summer.

Second, water the flowers in autumn.

For those dormant and semi-dormant flowers in autumn, it is better to control watering and keep the pot soil dry. Flowers that like shade or semi-shade should gradually increase their lighting time as the weather turns cool, and flowers that have already bloomed should be watered in time. Watering should be done twice a day, from 9 am to 10:00 (negative plants are relatively less), and appropriate amount of water should be watered in the evening. If the weather is hot and dry, you can spray foliar fog sooner or later, and water the ground around the flowers at the same time.

Third, matters needing attention.

The quality of ① watering. Potted flowers are best watered with soft water, with Rain Water as the best, followed by river water and well water, and tap water should be hung for a day. ② watering method. Most flowers like spraying, spraying water can lower the temperature, increase environmental humidity, reduce plant evaporation, wash foliar dust, and improve photosynthesis. Often sprayed flowers, clean branches and leaves, can improve the ornamental value of plants, but blooming flowers and hairy flowers should not spray water. The temperature of ③ water. There should be no big difference between the watering temperature and the air temperature at that time. If the water with large temperature difference is suddenly irrigated, the temperature of the root system and soil will suddenly drop or rise, which will hinder the normal physiological activity of the root system, weaken water absorption, and cause physiological drought. Therefore, watering at noon is avoided in summer, and watering in the morning and evening is appropriate. In order to judge the water demand of plants by ④, it is necessary to gradually explore and find out the law in practice, to master the amount of water to be watered, the general potted flowers to "see wet and dry", and woody flowers and cacti to master the principle of "dry and wet". Cold water is not suitable for watering flowers at noon in ⑤ in hot summer. If cold water is poured at this time, the soil temperature will suddenly drop, and the root hair will be stimulated by low temperature, which will immediately hinder the normal absorption of water, thus causing the foliar cells to change from tense to wilting, causing the plant to produce "physiological drought" and scorching the leaves. In severe cases, it will cause death of the whole plant.
