It is fairly common in affected regions and often becomes the "cancer" of jujube cultivation. At present there are several treatments

Nine key points to master when planting jujube trees in autumn
Planting jujube trees in autumn brings early sprouting, early flowering and stable fruiting. Moreover, as the temperature gradually drops, wounds on the underground roots heal quickly, evaporation from the above-ground part is small, and the survival rate is high. When planting jujube trees in autumn, pay attention to the following nine points. 1. Planting time. The earlier jujube trees are planted in autumn, the higher the survival rate.

Pruning Jujube Trees in Three Stages Helps Increase Yield
I. Trees in the early fruiting stage. The canopy of the jujube tree has not yet formed, and vegetative growth still predominates, but the yield increases year by year. Pruning at this stage should focus mainly on thinning, renewal pruning, heading back, and training, carried out according to the principle of "four keep, five do not keep." The "four keep" means: keep the outer jujube heads; keep the jujube heads on the scaffold

How to prevent and control infectious gummosis in peach trees
It is a disease caused by a fungus of the Ascomycota subphylum. It mainly harms branches and trunks. When it occurs on 1-year-old young shoots, small protrusions first appear centered on the lenticel layer, later forming tumor-like protrusions 1 to 4 mm in diameter, and no gum flows that year. By early April of the following year, the tumor

Management Measures and Technical Points for Peach Trees After Fruit Harvest
Most peach tree varieties mature early, and there is a long growth period from fruit harvest to leaf fall. This is precisely the critical period for nutrient accumulation and flower bud differentiation in peach trees, and the quality of management will directly affect the peach trees' overwintering and the growth and fruiting of the following year. Therefore, after fruit harvest, peach trees should adopt

What are the key points of summer management techniques for peach trees?
1. Carry out summer pruning well. 1. Arrange the main and secondary branches properly. 2. Remove water sprouts with branches in the inner canopy. 3. Fruit-bearing branches without branches, about 40-50 cm long, can be twisted. 4. Where the inner canopy is relatively empty and there is extension, semi-slanting branches can be cut back to cultivate into branch groups.

How to manage peach trees in summer? Detailed explanation of key points for peach orchard management
Summer is an important period for peach tree shoot growth and fruit enlargement. Strengthening peach orchard management is the key to increasing production in the current year and achieving a bumper harvest next year. 1. Fertilize according to the tree: In late May, apply a topdressing to peach trees that bear more fruit this year and have weaker tree vigor. Conversely, for trees with

Detailed Explanation of Key Technical Points for Spring Management of Peach Trees
Spring management of peach trees mainly refers to the management during the period before bud break, bud break, flowering, fruit set and fruit development. Its main technical points are as follows: 1. Fertilization. Peach tree branches and shoots grow rapidly and the fruit development period is short, so fertilization should be timely and reasonable. Spring fertilization

What are the key points to note in shaping and pruning peach trees
1. The general shaping principle is "shaped but not rigid, unshaped but not chaotic," "large branches bright and open, small branches bustling." Fewer large branches allow more small branches. The general pruning principle is "prefer light over heavy, combine heavy and light." "Small branches bustling" does not mean the more branches the better; generally after pruning the branch spacing is

Key Management Techniques for Greenhouse Peach Trees Before Dormancy
Forced dormancy of greenhouse peach trees by covering with a shed is generally carried out from mid-October to mid-November. The management in the 10 days before covering the shed for forced dormancy is very important; poor management directly affects the increase in fruit set rate, yield and quality. The key management measures for this period are as follows: Foliar fertilizer spraying for strength
