What are the key points of summer management techniques for jujube trees?
1. Increasing fruit set rate (1) Remove root suckers. Root suckers consume a large amount of nutrients, and any root suckers found should be dug out promptly. (2) Remove buds and pinch off tips. Control the sprouting of jujube heads; all new buds with no space in the inner canopy should be removed, leaving only a few jujube hanging fruiting shoots. (3) Girdling. When 30%-40% of the flowers have opened, trunk girdling can be carried out. The width of the girdle should be 1/10 of the trunk diameter. It should be done without damaging the xylem, and the girdle cut should have no ragged edges. After girdling, apply a 200-fold solution of carbendazim and seal it with clear adhesive tape. (4) After girdling, spray the plant with 2.5-3.5 kg of ice in the morning or afternoon. Alternatively, during the flowering period of jujube trees, spray 5 ppm of 2,4-D or 10 ppm of sodium naphthaleneacetate solution.

Detailed Explanation of Key Points of Wax-Sealing Technology for Jujube Scions
I. Benefits of Wax Sealing 1. Wax-sealing the scion forms a thin wax film on the scion surface, sealing the stomata of the scion epidermis and the cuts at both ends of the scion, reducing water evaporation by more than 90% compared with ordinary scions, thus protecting the scion. 2. The grafting period is long; jujube branch grafting is generally

Key Technical Points for Soil, Fertilizer and Water Management in Jujube Orchards
After jujube trees enter the full fruit-bearing stage, doing a good job of soil, fertilizer and water management and maintaining a good tree vigor are the prerequisites for high yield and quality. The soil, fertilizer and water management of jujube trees in the full fruit-bearing stage can be summarized as two tillages, four fertilizations and three waterings. The two tillages refer to deep plowing and intertillage. Deep plowing can loosen the soil in the jujube orchard,

How to Graft a Jujube Tree? A Detailed Guide to Practical Grafting Techniques
Jujube tree grafting can still be carried out from July to September, and at this time, because the jujube branches grow vigorously and the graft buds develop plumply, the grafting survival rate is relatively high. I. Bark grafting method Collecting scions Select new-growing jujube shoots of excellent varieties suitable for local cultivation that are 1 to 2 years old

Key Technical Points for Planting and Management of Winter Jujube Trees During the Dormant Period
In November, winter jujube trees enter the dormant period, which is a favorable time for planting winter jujube. The main work this month includes applying base fertilizer, protecting the tree body, and building new orchards. 1. Applying base fertilizer: Applying base fertilizer at this time, when ground temperature is high and soil moisture is abundant, allows fertilizer to decompose quickly and facilitates root absorption.

Technical Key Points for Applying Biogas Fertilizer to Apple Trees
In addition to being rich in the major elements nitrogen, phosphorus and potassium, biogas fertilizer also contains trace elements such as boron, copper, iron, manganese, calcium and zinc that play an important role in fruit tree growth, as well as large amounts of organic matter, various amino acids and vitamins. In addition, applying biogas fertilizer can significantly

Detailed Explanation of Key Technical Points for Soil Management in Apple Orchards
I. Ridge raising and mulching. 1. Dig fertilization pits (this can be done together with the application of base fertilizer). On the inner side, 30-40 cm vertically below the extended branches on the outer periphery of the tree canopy, dig 2-4 fertilization pits each 40 cm long and 40 cm wide and 50 cm deep (the depth for topdressing is 20 cm). 2. Dig trenches and raise ridges. Outside the fertilization holes, along the row direction

6 Key Techniques for Apple Seedlings to Survive After Planting
1. Scientific storage, planting at the right time. For seedlings, winter storage (heeled-in) and planting in spring when local apple buds begin to swell are best. For heeling in, choose a shaded spot that does not collect water and dig a trench, maintaining stable and suitable moisture and temperature; when heeling in, make sure the roots are in close contact with moist sand (soil). 2. Do

Detailed Explanation of Fertilization Techniques for Fruiting Mango Trees
Fertilization of fruiting mango trees should follow the principle of reasonably adjusting the contradiction between vegetative growth and reproductive growth. It is necessary both to promote flowering and fruiting in the current year and to control excessive summer shoot growth, and also to promote the sprouting and robust growth of autumn shoots, so as to lay a good foundation for continued bumper harvests in the following year. Fertilization

Detailed Explanation of Flowering Period Regulation Techniques for Mango Cultivation
Mangoes in Guangdong generally bloom around February each year. At this time, they often encounter the influence of cold air from the north moving south, with low temperatures, continuous rain, and high air humidity, causing anthers not to split open, stigma damage, and even flower panicle mildew and death, affecting that year's fruiting. According to expert
