After the beginning of heat, it is considered the hottest stage of summer. Most areas will experience a period of high temperatures. In the management of jujube trees after the beginning of heat, the following points need attention:
-
Scientific Pruning
Jujube trees are plants that thrive in sunlight. Poor sunlight can lead to excessive elongation of the tree, increased fruit drop, and a higher incidence of pests and diseases. In mid-August, it is important to timely thin out crowded branches, excessive elongated branches, diseased and pest-infested branches, and weak branches. Except for the main branches responsible for expanding the canopy, appropriate topping should be carried out to improve the sunlight conditions and nutrient distribution of the tree, promoting accelerated fruit growth. Wounds caused by pruning should be promptly coated with wound healing and antiseptic film to protect against infection by pathogens.
-
Proper Fertilization
In early August, nitrogen fertilizer should not be applied to jujube trees with normal growth and fruiting. Phosphorus and potassium fertilizers should be applied appropriately. Jujube trees with abundant fruiting but weak growth can be fertilized more. Meanwhile, spraying with "Zhuangguo Dilin" can activate the ecological growth energy of plants, broaden the plant vascular pathways, enhance the plant's water and nutrient absorption capabilities, increase fruit yield and quality, reduce fruit drop rate, and decrease the occurrence of fruit cracking, fruit hardening, and deformed fruits.
-
Pest and Disease Prevention
Spraying "Xin Gao Zhi Mo" 600 times solution on the leaf surface in the morning or afternoon can automatically form an invisible high-molecular-weight protective film, optimizing the quality of plant water absorption, air permeability, and light transmission. It blocks pest feeding signals and weakens transmission media, resisting and defending against natural environmental disasters.
-
Drainage and Drought Prevention
For mountain orchards, it is important to repair fish scale pits, reservoirs, and other water collection facilities to accumulate rainwater and prevent autumn drought. For plain areas, drainage ditches in jujube orchards should be cleared. In the event of continuous rainfall, stagnant water should be promptly removed to prevent waterlogging.
Jujubes are not only delicious but also have various health benefits. Currently, they have a promising market prospect. The dog days of this year are approaching, so everyone should prepare measures promptly.
