Causes and prevention methods of towel gourd deformity

The most headache in the growth of towel gourd is deformed gourd, which is an important physiological problem in towel gourd production, which leads to many abnormal causes, such as lack of fertilizer and water, high temperature, diseases and insect pests and so on. So how to prevent loofah deformity? Let's take a look at the detailed introduction.

1. Insufficient supply of fertilizer and water

Towel gourd plants lack of drought for a long time, or the root absorption capacity is weak, which can not guarantee the supply of nutrients needed for the normal growth of towel gourd, which will lead to plant malnutrition, plant weakness and poor fruit growth, even abnormal phenomenon.

Prevention and control methods: to ensure the supply of fertilizer and water, timely fertilization to provide soil fertility, improve the absorption capacity of towel gourd roots, timely watering during drought to keep the soil moist, so as not to affect the root absorption capacity of soil drought. Timely root irrigation can trap and kill root diseases and insects, promote root development and provide sufficient nutrients for plants.

2. Lack of light

Towel gourd likes crops with plenty of light, which may cause abnormal symptoms of curved gourd if the fruit development time is insufficient or the continuous low light environment.

Control methods: during fruit development, it is necessary to prune the withered leaves, yellow leaves and dense leaves, so as to increase the ventilation and light transmittance in the field, increase sufficient light for fruit development and reduce the phenomenon of curved melons.

3. Large temperature difference between day and night

During the growth and development of towel gourd, a certain temperature difference between day and night can promote the expansion of the fruit, but if the temperature difference between day and night is too large, the fruit will be deformed. If there is no timely ventilation when planting in the greenhouse, it will also cause deformed fruit if the temperature in the greenhouse is too high.

Prevention and treatment: when planting, we should pay attention to the night temperature, its nutrition will be over-consumed, and there will be deformities due to dysplasia during fruit development. When the temperature in the shed reaches 31-33 degrees, it is necessary to guard against the wind in time, lest the temperature in the shed is too high, and when the outdoor temperature is too low, you should pay attention to opening the tuyere slowly to avoid sudden rise and fall of the temperature in the shed.

4. Improper pollination

During the period of towel gourd pollination, if the external environment is improper, such as high temperature and poor field permeability, it will cause poor pollination. In addition, if the correct measures are not taken during flower lighting, it will also cause insufficient pollination of female flowers and cause fruit deformities.

Control methods: to control plant growth, inhibit main shoot growth, promote flower bud differentiation, make it blossom more, improve pollen treatment, and increase fruit setting rate. Spraying strong melon stalks many times before flowering can promote the growth and development of floral organs, improve the quality of pollination and reduce the incidence of abnormal fruits.

The above is the introduction of the causes and prevention methods of towel gourd deformity. I hope it can help you. If you want to know more about it, please pay attention to us.
