What are the causes of melon fruit abortion and the control methods?
1. Causes of fruit abortion 1. Temperature too high or too low. When the temperature is too high, photosynthetic accumulation is low and respiration consumption is high, which easily causes the vines to grow excessively, leading to malnutrition and fruit abortion; when the temperature is too low, the root absorption capacity weakens, affecting photosynthesis and leading to nutrient deficiency and fruit abortion. 2. Soil too dry

Key Technical Points for Greenhouse Management of Muskmelon After Transplanting
1. Greenhouse temperature regulation After transplanting, in the early stage, in order to raise the greenhouse temperature and promote seedling recovery, the greenhouse film should be fastened tightly, and the straw mats should be uncovered and covered in a timely manner; before flowering and fruit setting, the daytime greenhouse temperature should be maintained at 25-28°C, and at night at 16-18°C. When the greenhouse temperature exceeds 28°C, the greenhouse film should be opened for ventilation. As the plants grow

Methods for preventing and treating Fusarium wilt in melons, a must-read for growers
Symptoms This disease can occur throughout the entire growth period of melons. When seedlings are infected, the leaves of the diseased seedlings become lighter in color, gradually wilt, and finally die. When the stem is cut open, the vascular bundles can be seen to have discolored. When the disease occurs during the mature plant stage, the leaves of the plant wilt and droop from bottom to top, some leaf edges turn brown or produce brown necrotic

How to prevent and control fruit cracking in pomegranates during the ripening period? A detailed guide to practical methods
1. Plant crack-resistant varieties This is the fundamental measure for preventing fruit cracking. Priority should be given to this measure when developing pomegranates. Among the excellent pomegranate varieties, Heyin Tonghongdeng pomegranate, Heyin Yueliangbai pomegranate, Heyin Hongdeng pomegranate, Tunisian soft-seed pomegranate and Chaodazi pomegranate are all

What are the control methods for the tea bagworm on pomegranate trees?
1. Manual control Manually remove the bagworm bags hanging on the branches and destroy them in a centralized manner. It is more convenient to do this during the dormancy period of the fruit tree, but care should be taken to protect natural enemies. This method has a thorough control effect and is safe for pomegranates, but if the orchard area is large, it is time-consuming and labor-intensive. 2. Chemical control

Detailed Explanation of Key Management Techniques for Pomegranate During the Fruit Enlargement Stage
1. Intertillage and weeding. In summer, weeds in the orchard grow severely and compete with the fruit trees for water and nutrients. Intertillage can not only remove weeds (chemical weeding may be used when necessary), but also loosen the soil and prevent soil moisture evaporation. However, during this period the root activity of the fruit trees is vigorous, so to prevent

What are the shaping and pruning methods for pomegranate trees?
Strong sprouting ability of latent buds and high tolerance to pruning are the greatest characteristics of pomegranate. This creates favorable conditions for shaping, but the shortcoming is that its branches sprout readily, the tree shape easily becomes messy, and this affects ornamentation. To make pomegranate produce more flowers, more fruit, and beautiful form, it is necessary

How to prevent twig dieback in young pomegranate trees in severe winter? Detailed explanation of cold protection methods
Twig dieback in young pomegranate trees refers to the phenomenon in which some branches shrink and dry out or die after the tree overwinters. In northern China, winters are cold and dry, early spring has little rain and much wind, and evaporation is high, while young pomegranate trees grow a lot each year and the pith of the branches has poor water retention. Therefore, in a severe winter, twig dieback is likely to occur.

Post-harvest Management Techniques for Pomegranate
In early to mid-September, pomegranates ripen successively and enter the harvest stage. Post-harvest management must be carried out promptly to accelerate tree vigor recovery, strengthen fruiting mother branches, and lay a good foundation for high and stable yields next year. Clear weeds, dead branches, fallen leaves and fallen fruit from the orchard, prune
