Causes and Control Methods of Fruit Cracking of Newest Gonggan
Gonggan seedling emperor orange is a kind of fruit that people like in life. It is planted in many areas of our country. However, fruit cracking occurs in the process of planting Gonggan, which seriously affects the yield and quality of Gonggan and reduces the income. So what is the cause of the orange cracking fruit? How to prevent it? Let's take a look at the detailed introduction.
1. Causes of fruit cracking
Fruit cracking usually occurs in Gonggan, which is mainly related to water content. If the water content is insufficient, the fruit will be less and the fruit drop will occur. If the water content suddenly increases, the fruit cracking phenomenon will easily occur. Fruit cracking generally occurs during the fruit expansion period to the color transformation period, and fruit cracking will occur in case of rain for a long time. In addition, the fruit cracking of Gonggan is also related to calcium deficiency. When the plant is deficient in calcium, calcium deficiency in pericarp will lead to reduced toughness. When the flesh absorbs water and expands, the pericarp growth cannot keep up with the flesh growth, and the flesh will directly burst it.
II. Control methods
1, increase the application of organic fertilizer
In the autumn shoot period, organic fertilizer should be added, combined with quick-acting compound fertilizer, and it should be treated according to the formula balanced fertilization method, which is beneficial to coordinate the supply of nutrients such as organic fertilizer and inorganic fertilizer, promote the balanced growth of pulp and pericarp, make the cell density of pericarp high, enhance toughness and reduce fruit cracking phenomenon.
2, foliar fertilizer
During the fruit expansion period, foliar fertilizers such as calcium and magnesium should be sprayed in due time to effectively supplement the trace elements such as calcium and magnesium that the plants lack. Attention should be paid to the concentration when spraying foliar fertilizers.
3, do a good job of water management
In summer, when it is hot and rainy, the waterlogging in the garden should be removed from drought in time, so as to avoid the phenomenon of suffocation and rotten roots caused by soil oxygen content caused by accumulation of water in the garden, resulting in tree weakness and plant yellowing. In autumn, when the climate is dry, proper watering is needed to keep the soil moist, but it is also necessary to avoid prolonged drought and sudden rain, which causes a large amount of fruit absorption and causes cracking.
The above is an introduction to the causes and prevention methods of citrus fruit cracking. I hope it can help you. If you want to know more about it, please pay attention to us.
