A normal cucumber should be a round stick with even top and bottom, but there will be abnormal phenomena in actual cucumber planting. Deformed cucumber not only affects the yield, but also reduces the quality of cucumber. What is the reason why cucumber has deformed melon? And how to prevent the occurrence of deformed cucumbers. Let's talk about the causes and preventive measures of cucumber deformity.
First, the symptoms of deformed melons.
1. Curved melon: During the development of melon strips, they are not straight, but bent to one side to form a T-shape, an O-shape or a semi-O-shape, which reduces the weight of a single melon and affects the quality.
2, pointed-billed melon: the melon handle near the shoulder is thicker and the front end is thinner, like a carrot.
3. Honeycomb melon: the melon strips develop normally from top to bottom, but slowly in the middle, forming two thick ends and a thin middle. The shape of the melon is similar to that of a slender-waist bee, with a hollow core and crisp melon strips.
4, pot-bellied melon: the handle of the melon is very thin, and the lower part is excessively expanded to form a melon with an uncoordinated proportion.
6. Old melon: Old melon is characterized by short and thick cucumbers on the seedlings, which are yellowish in color and look like melon eggs, commonly known as old melon.

Second, the causes of cucumber deformity.
Deformed melons include big-bellied melons, thin-waisted melons and pointed-billed melons. Their appearance is mainly due to uneven nutrient supply or boron deficiency. Malnutrition, abnormal temperature, insufficient water supply and poor pollination make the accumulation and supply of assimilates in plants unbalanced. Before flowering and sitting, the supply of boron was short, the ovary of female flower was not fully developed, and the young melon began to appear thin waist. The main reason why cucumber has a big belly and a sharp mouth is that the female flower is pollinated too late, and the top expands first after pollination. In the early stage of fruit expansion, due to insufficient nutrition supply or drought, melons with sharp bellies will be formed. Affected by this disease, botrytis cinerea is easy to appear pointed-billed melon, and scab disease is easy to appear deformed melon. In addition, too much phosphorus and potassium fertilizer is applied, and it is prone to short and thick melon strips, which are unhealthy, tender and dull.
