Causes and control methods of malformed fruits in the latest muskmelon

Melon has delicate flesh and sweet taste. It is a kind of fruit suitable for all ages. It is very popular in the market. However, due to the planting environment and improper management, melon fruit grows abnormally, which seriously affects the commodity rate and reduces the income of fruit growers. So what is the cause of melon malformed fruit? How to prevent it? Let's take a look at the detailed content introduction together.

1, flat fruit

Flat fruit is caused by the failure of young fruit to fully develop longitudinally before growth. The main reason is that the leaves are small due to insufficient nutrition of the plant, and the fruit is stunted due to insufficient nutrition supply. In addition, during the fruiting period, the lower or higher temperature of the planting environment will also cause the appearance of flat fruit; controlling water in the early flowering stage and watering a lot of water in the late stage will also cause the melon to form flat fruit.

Control methods: timely fertilization to provide plant growth needs, so that it has sufficient nutrients to grow and bear fruit normally; improve the temperature of the planting environment, keep the temperature at 23-34 degrees when the fruit just grows and develops, and keep the temperature at 27-30 degrees when it reaches the rapid expansion period; pay attention to watering methods during flowering, and do not excessively control water.

2. Long fruit

Opposite of flat fruit. It is caused by the longitudinal diameter being larger than the transverse diameter when the fruit grows. The leaves are larger, the photosynthesis is strong, and the synthesized nutrients are sufficient, which leads to the rapid growth of the fruit in the early stage. In the late stage, due to the premature senescence of the plant or the withering of the leaves, the nutrients drop sharply and form a long melon.

Control methods: strengthen fertilizer and water management of plants, prevent premature senescence of plants due to lack of nutrients, strengthen leaf management, prevent diseases and insect pests from damaging leaves, strengthen illumination, and make leaves continuously synthesize nutrients.

3, small fruit

Small fruit shape and normal fruit no obvious difference, but the weight is far lighter than normal fruit, generally in the growth of mature, weight more than 200 grams are considered small fruit. The main reason is that the planting growth is weak, and the leaves are few, so they cannot synthesize sufficient nutrients for the growth of plants and fruits; in addition, the number of fruits of plants is too large, and the nutrients are too scattered, which will also form small fruits; the excessive nutrition of plants misses the best fruiting time, resulting in insufficient nutrition of fruits.

Control methods: strengthen fertilizer and water management in early growth, so that plants grow strong, plant growth is too weak, remove some fruits, so that the rest of the fruit has enough nutrients to grow; artificial pollination to promote fruit setting.

4. Fruit cracking

Cracking fruit is melon surface cracks, these cracks are large and deep, when serious, the whole melon can be split into two halves, seriously affecting the quality, the cause is that the fruit epidermis is too hard, in sunny weather after exposure and rainy season irrigation too much, will cause cracking fruit.

Prevention and control methods: select varieties with less cracked fruit, irrigate reasonably, water less or not during fruit expansion period, drain water in time to prevent waterlogging in rainy season, avoid excessive root water, shade and avoid sun in time when sunlight is strong, and prevent direct sunlight from irradiating fruits.

The above is the cause of melon abnormal fruit and prevention methods, I hope to help you, want to know more melon planting knowledge, please pay attention to us.
