Control Methods for Scab Disease in Mango Cultivation
1. Symptom characteristics: It mainly damages the fruit, and young new shoots and leaves can also be affected. All affected parts show rough, slightly raised scab spots that are lignified. Small dark brown, slightly raised, lignified spots first appear on the fruit surface; later the lesions become densely packed and merge into patches, with a rough surface and a sunken center.

Control Methods for Mango Flatid Planthopper
The mango flatid planthopper, also called the leafhopper, damages flower spikes and young fruit, causing flower and fruit drop, poor harvest or even total crop failure, and induces severe sooty mold. It also damages young buds, tender shoots and leaves, causing bud and leaf deformity. It usually occurs more frequently during the flowering period, and high humidity and a dense canopy make this insect more likely to appear.

How to Overcome Alternate Bearing in Mango? Detailed Explanation of Cultivation Measures
To overcome alternate bearing in mango, the first requirement is to have an appropriate amount of flowers; the second is to have the flowering period avoid low-temperature rainy weather; the third is to find ways to increase the fruit-setting rate. The measures are: 1. Selection of varieties According to the characteristics of Guangxi's early spring, which is mostly low-temperature rainy weather, it is ideal for mango to bloom after early April.

Detailed Guide to the Method of Cultivating Mango Grafting Rootstock Seedlings
In monoembryonic mango varieties, a single seed produces only one seedling, while polyembryonic varieties can germinate and grow into multiple seedlings. A monoembryonic seed has only one embryo (a sexual embryo); the embryo is large, and the single seedling it develops into is vigorous. A polyembryonic seed has multiple embryos; the embryos are smaller, and the multiple seedlings they develop into are weaker

Mango Top Grafting and Replanting: Operation Methods and Key Technical Points
Over the past decade, mangoes have been planted in contiguous orchards on hillsides throughout the south, and production has developed rapidly. However, large trees and new trees that have been planted for many years need top grafting and replanting due to poor quality or mixed varieties and low yields. The methods are: 1. Preparation before grafting. Before replanting, strengthen fertilizer and water management for the trees to be replanted. Prune the aboveground parts appropriately, removing diseased branches, dead branches, shaded branches, overly dense branches, and crossing branches; for perennial large trees, in spring and autumn, saw off the main and lateral branches at 1.2-1.5 m above the ground (saw in spring and graft in autumn, or saw in autumn and graft the following spring), leaving some small branches. After new shoots emerge from the saw cuts, keep only 2-3 evenly distributed new shoots per cut. After the new shoots mature and their diameter reaches 0.5-0.8 cm or more, grafting can be done on the new shoots. Stop fertilizing 15 days before grafting, which can slow sap flow and benefit grafting.

What ecological conditions are needed for mango cultivation
I think everyone is very familiar with mangoes. Many people in daily life like to eat mangoes, but mangoes contain certain components, and some people develop an allergic reaction after eating them. Therefore, although mangoes are delicious and highly nutritious, they are a tropical fruit

What management work needs to be done before planting mangoes in the field?
1. Marking out Marking out and digging holes: The orchard is first plowed twice and harrowed twice, with deep turning and ripening to a depth of 30cm. For orchards on hillsides, planting is done along the contour. First, from top to bottom, establish a vertical baseline, and according to the baseline and the plant spacing, mark out the planting points for two contour planting rows at the middle and foot of the hillside to the left and right. Then, using two points to form a line, mark out the planting points for the other contour planting rows. For flatland orchards, use the main road and branch roads as baselines and mark points according to the specified plant and row spacing, with each planting row parallel or perpendicular to the roads. The planting hole size is 80×70×60cm, and holes should be dug 2-3 months before planting.

How to control the mango tree borer (Chlorophorus annularis)
Distribution and damage: it occurs both at home and abroad, and in China it occurs to varying degrees in Yunnan, Guangdong, Guangxi, Fujian and other places. The larvae bore into and feed on the branches of fruit trees such as mango and cashew, usually entering from young branches and gradually boring downward to large branches and the trunk, seriously affecting

Detailed Explanation of Key Techniques for Mango Cultivation
This variety was introduced from Thailand in 1990, and after several years of selecting the best from a population of asexually propagated superior individual plants, it was developed through selective breeding. After four consecutive years of multi-point planting trials from 1996-1999 in Guangdong, Guangxi, Yunnan and other places, its various superior traits showed stable genetic
