So what is the reason for its orchids? Let's take a look at the pro-farm network.

1. Causes of rotten flowers

Towel gourd flowers are large but thin, often due to some small collisions in planting will lead to flowers wounds, especially during the dipping period, thus infected with bacteria, resulting in rotten flowers. Lack of calcium and boron elements will also lead to rotten flowers, some farmers in order to increase yield, often apply a large amount of potassium fertilizer, resulting in the absorption of calcium and boron fertilizer, reduce the hardness of the cell wall, resulting in dry rot. In addition, the improper management of orchids is caused by improper ventilation when planting, and the speed of ventilation is fast, which makes the cold air blow in very quickly, causing the flowers to dry and rot.

2. Preventive measures

Strengthen cultivation management, spray foliar fertilizer to increase plant nutrition, do not cause damage to flowers, be careful when dipping in flowers, slowly and slowly to prevent cold air from blowing in in an instant. Some farmers habitually water after dipping flowers to speed up the expansion of fruits, which is actually a wrong method. Watering immediately after dipping flowers will make the stems and leaves grow, seize the nutrients of the fruits, and affect the growth of fruits and melons. On the other hand, it will also cause high air humidity, making flowers more likely to be infected with pathogens, counterproductive, resulting in a large number of flowers and orchids, so it is not suitable to water immediately after dipping flowers. The transition period should be maintained for at least three days. When dipping flowers, choose at noon, because at least the temperature is high, the air humidity is low, the flowers are more resistant after dipping flowers.

3. Prevention and control methods

If it is the rotten flower caused by the disease, identify the disease in time, prescribe the right medicine to avoid the spread of rotten flower, if it is impossible to distinguish that kind of disease at the moment, spray carbendazim 800 times liquid + difenoconazole 800 times solution + chlorothalonil 500 times liquid spray control, the effect is remarkable, can control most fungal and bacterial diseases. In the case of dried and rotten flowers, timely spraying foliar fertilizer or fertilizing the soil, because dry rotten flowers are mainly caused by lack of nutrition.
