Once crops have cracked fruits, it can lead to poor sales, decreased quality, poor taste, many diseased fruits, and pitifully low prices, seriously affecting the profitability of growers.
Is it really impossible to prevent these problems? Of course not!!!
Why is prevention necessary? Based on years of experience, once fruit cracking begins, prevention and control measures are generally ineffective. Therefore, only by recognizing the causes of fruit cracking and doing a good job in daily prevention and control can we not only prevent fruit cracking, but also play an important role in other management. This way, our planting economic benefits will be greatly improved.
Reasons for fruit cracking
The cracking of fruits is caused by a combination of internal and external factors, with the internal factors mainly being genetics and the fruit’s own characteristics, such as size, shape, growth rate, etc; The external factors mainly include growth environment conditions such as temperature, light, precipitation, as well as cultivation and management methods. In the process of fruit tree management, we often adjust the production conditions through agricultural operations to regulate whether the fruit cracks or not. Therefore, it is important to understand the external factors that affect fruit cracking.
Issue with variety
The issue of fruit cracking is closely related to the physiological and genetic characteristics of the variety. The fruit size, peel thickness, fruit moisture content, cell density, sugar and acid content, and peel development quality of a variety can all affect fruit cracking.
Imbalance of nutritional elements
Imbalance of two nutrients can cause fruit cracking, such as the lack of phosphorus, potassium, and calcium during fruit growth, which has a significant impact on fruit cracking. The principle is that when one or more elements are excessive while the content of other elements is low, fruit cracking will increase.
Weather factors
1. Temperature
Continuous high temperatures and sudden drops in temperature can increase the cracking rate of fruits. The reason is that high temperatures can affect the water flow of plants, such as water absorption and transpiration rates;
2. Illumination
Light exposure can cause an increase in surface temperature of the fruit, leading to fruit cracking; Strong light conditions accelerate the accumulation of soluble solids and growth rate in fruits, leading to fruit cracking; Intense light exposure may cause damage to the fruit peel, affecting the integrity and mechanical strength of the peel and cuticle, and increasing the probability of fruit cracking.
3. Rainfall
Large or irregular rainfall can cause fruit cracking, mainly due to the instantaneous absorption of a large amount of water by the plant roots, resulting in changes in fruit moisture content and causing fruit cracking. At the same time, rainwater can also be absorbed into the fruit through the stomata of the skin, causing local skin cells to absorb water and burst, leading to fruit cracking.
4. Deficient element
Neglecting the supplementation of trace elements during the growth process can lead to nutrient deficiency and cause fruit cracking. Calcium is an important component of plant cell walls, and a decrease in calcium content reduces the mechanical properties of fruit peels, leading to fruit cracking. Boron is also crucial for the integrity of cell walls, and its deficiency can increase the likelihood of fruit cracking. At the same time, there is an antagonistic effect between elements, such as calcium and potassium. When the content of either one is higher than the other, the fruit cracking rate will actually increase.
To solve the problem of fruit cracking, in addition to normal fertilizer and water management, we can choose a good crack prevention product to protect crops. I recommend the non-woven cloth bag that everyone is using. The fabric adopts lotus leaf biomimetic technology, which has a rainproof and hydrophobic effect. At the same time, it is also ventilated and fresh to prevent the harm of high temperature heat accumulation and burning of fruits and leaves, ensuring that the fruits are fresh and full!
When it rains, covering the farmer’s first grade plum protection cloth can prevent rainwater from invading and causing the plums to crack, resulting in fruit cracking! When the temperature is high, covering the farmer’s first grade plum protection cloth can block direct sunlight, improve the heat resistance of plum trees, effectively reduce the temperature inside the film, reduce the burning of fruits, and also reduce water evaporation. At the same time, it can make the shed dry and comfortable, with a suitable temperature, which can effectively prevent and reduce the cracking of plums in high temperature weather.
Measures to reduce fruit cracking rate
1. Fruit bagging
Fruit bagging keeps the fruit in a relatively stable environment, avoiding fluctuations in surface temperature and direct contact between the fruit and rainwater during rainfall. This greatly reduces the probability of fruit cracking.
2. Reasonable irrigation
Maintain soil moisture stability, avoid excessive irrigation or drought, ensure the necessary water supply for crop growth, and reduce the likelihood of fruit cracking.
3. Grass proof cloth
The breathable holes of Liansheng’s first grade grass proof cloth are uniform and fine, suitable for the growth of earthworms, microorganisms, etc. in the soil, and increase the nutrient content of the soil. And the fabric surface is evenly permeable, allowing rainwater and liquid fertilizer to penetrate, preventing root rot and avoiding local water accumulation to cope with adverse weather conditions. Such as high temperatures, continuous rainfall weather, etc.
4. Application of rain shelter facilities
The application of rain shelter facilities in production management greatly improves the ability of plants to cope with continuous rainfall weather, thereby greatly reducing the probability of fruit cracking and the occurrence of diseases.
5. Reasonable pruning
Reasonable pruning ensures ventilation and light transmission of fruit trees, ensuring the normal growth of fruits.
6. The use of plant regulators
Plant growth regulators can regulate the growth and development of plants and have a certain impact on fruit cracking. Gibberellin has the ability to delay fruit ripening; Increase skin elasticity; Increasing the plasticity of cell walls and maintaining fruit hardness can reduce the likelihood of fruit cracking.
Dongguan Liansheng Nonwoven Fabric Co., Ltd., a manufacturer of non-woven fabrics and non-woven fabrics, is worthy of your trust!
