Detailed Explanation of the Causes of Deformed Pepino Melon Fruit and Control Methods
Pepino melon, also known as pepino or melon pear (Solanum muricatum), originated in South America. Because its skin turns golden yellow when ripe and its shape resembles a human heart, it is called "heart fruit." It is nutritious and a very popular fruit. It is currently cultivated in many places in China, but due to the influence of climate differences, many people encounter many problems when growing it, and deformed fruit is one of them. Let's take a look at the control methods for deformed pepino melon fruit below.
1. Poor flower bud differentiation
During the flower bud differentiation stage of pepino melon, if it is kept under low temperature conditions of 8-10°C for a long time, it will cause poor flower bud differentiation and lead to deformed pepino melon fruit. This generally occurs on the first to second fruit clusters at the lower part of the plant.
Control measures: Strengthen seedling-stage management of pepino melon, prevent the seedbed humidity from being too high or too low, and prevent the day-night temperature difference from being too large. At the same time, strengthen fertilizer and water management, apply organic fertilizer in a timely manner, ensure a comprehensive and balanced supply of all nutrient elements, and prevent pepino melon plants from excessive vegetative growth and from forming aged seedlings.
2. Improper use of hormones
During the growing process, many fruit growers often use fruit-setting hormones to increase the fruit-setting rate. When hormones are used improperly or the hormone concentration is too high, and the supply of fertilizer and water is insufficient, it will cause deformed fruit development.
Control methods: When using fruit-setting hormones, be sure to note that the concentration should not be too high. In addition, the spraying time and method must also be correct.
3. Excessive vegetative growth of plants
When fertilizer and water are sufficient, plants often grow vigorously. This means vegetative growth exceeds reproductive growth, which often inhibits normal flowering and fruiting of the plant. Fruit development and growth do not receive sufficient nutrients, which often induces deformed fruit.
Control methods: Strengthen root management. Applying 800-fold diluted Jiamei Hongli 2-3 times can effectively prevent excessive vegetative growth and premature aging of plants.
