Causes and control methods of zucchini tip

Zucchini tip is a common physiological disease in the growth process of zucchini. Once infected with the disease, it is difficult to improve zucchini in the later development. So what is the cause of the zucchini tip? How to prevent and cure it? Let's get to know it with the editor.

1. Leave too many melons

When the weather is fine, zucchini grows relatively late, so many vegetable farmers will follow the method of keeping one melon per leaf, hoping to control the plant with fruit, resulting in too many melon strips and fierce competition for nutrition. as a result, a large number of melon strips become pointed melons because of lack of nutrition.

Prevention and control methods: it is suggested that when retaining melons, melon strips should be taken appropriately according to the growth of the plant, and 4-5 melons should be retained for each plant with relatively strong growth, and one melon per leaf should not be allowed. This will only cause too many melon strips, resulting in insufficient nutrients and the formation of pointed melons.

2. Fertilizer and water are unreasonable.

Many vegetable farmers use less fertilizer, resulting in insufficient nutrition supply of zucchini, resulting in an increase in the number of pointed melons, generally applying 30 kilograms of high-potassium fertilizer per mu, and in addition, during the melon-bearing period of zucchini, they cannot be watered in large quantities, nor can they be dry or wet all of a sudden, so as to avoid damage to the root system after watering, affecting the absorption and utilization of fertilizer by the root system.

Prevention and control methods: strengthen fertilizer and water management and appropriately increase the application of chemical fertilizer, because zucchini is a high-yield crop, and new melon strips are still being bred when the melon strips are enlarged, so in addition to applying sufficient basic fertilizer in the process of cultivation, attention should also be paid to the regular application of fertilizers to replenish nutrients.

3. Temperature and humidity are not suitable.

Zucchini do not like high temperature, especially the high leaf temperature, will lead to enhanced respiration, most of the nutrition is consumed, resulting in insufficient nutrition supply of melon strips, the emergence of melon tip, slow growth phenomenon.

Prevention and control methods: the temperature difference between day and night of zucchini should be large, it is best not to exceed 23 degrees during the day, and the temperature should be controlled at about 13 degrees at night. At the same time, attention should be paid to removing the old leaves in the lower part of the plant in order to strengthen ventilation, remove moisture and avoid drug damage. affect the photosynthetic efficiency, leading to the production of pointed melon.

4. The plant is flourishing.

Zucchini plants flourish, resulting in excessive vegetative growth, thus inhibiting the reproductive growth of plants, affecting the transformation of nutrients to young melons, resulting in the tip of zucchini.

Prevention and control methods: to do a good job of plant growth control measures, when the plant can be sprayed with multi-effect frustration and other growth control agents.
