What Causes Cherry Fruit Cracking? Detailed Explanation of Causes and Protective Measures

For many fruits, the most worrying phenomenon during cultivation is fruit cracking, and cherries are no exception. Cherry fruit cracking is a very troublesome matter. Once the fruit cracks, pathogens invade through the split, causing the fruit to rot, and once cracked, the fruit basically cannot be sold on the market, causing great economic losses to fruit growers. So what should be done about cherry fruit cracking? Are there any control measures? Below, Qinnong Net brings you the causes of cherry fruit cracking and control measures.

1. Unsuitable varieties

There are many varieties of cherries, and the characteristics of these varieties are all different, as are their cracking rates. Some varieties have firm flesh and thin skin, so the probability of cracking is relatively high, while some varieties have good flesh elasticity and a low probability of cracking. Some varieties have a high fruit-setting rate, which not only gives high yield, but during the fruit expansion period, because the number of fruits is large, the nutrients transported by the plant are relatively small, so expansion is slower and the cracking rate is low. Varieties with a low fruit-setting rate bear fewer fruits, and the plant transports more nutrients and faster, so they grow rapidly during the expansion period, resulting in a high cracking rate.

Control measures: Choose varieties resistant to fruit cracking for planting, solving this problem from the fundamental source.

2. Imbalance of soil and water

Some fruit growers choose sticky soil with poor drainage for planting, or apply mostly chemical fertilizers when fertilizing and basically do not apply organic fertilizer. This leads to long-term lack of many trace elements in the soil, and eventually the soil becomes hardened into blocks with poor permeability. The growth of the plant's root system is hindered, and the water storage and drainage capacity is poor. In the rainy season, the soil is prone to water accumulation, and during fruit expansion, too much water is absorbed, causing fruit cracking.

Control measures: Choose soil that is loose and well-drained for planting, use organic fertilizer or farmyard manure for fertilization, and try not to apply chemical fertilizers. Carry out intertillage and weeding 2-3 times each year, loosening the soil around the planting area several times to prevent soil hardening. Water promptly during drought and drain promptly during the rainy season.

3. Air humidity

Air humidity is also a major cause of normal cherry fruit cracking. During the fruit expansion period, sudden changes in air humidity can also cause fruit cracking.

Control measures: If planting in a greenhouse, the indoor humidity must be balanced, especially when the fruit is fully ripening; cherries can continue to grow while ripening, so humidity must be balanced. If planting in the open field, rain-shelter protective measures should be set up to reduce the cracking rate and the occurrence of bird damage. In addition, in cold regions, frost damage must also be prevented and controlled.
