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

Control Methods and Technical Key Points for Mango Powdery Mildew
Mango is prone to powdery mildew during the flowering stage, young fruit stage and tender leaf stage. If not controlled in time, it will cause massive fruit drop and reduce yield. Mango powdery mildew is a fungal disease that mainly affects inflorescences, young fruits and tender leaves. On affected organs, scattered small white moldy patches first appear,

What are the key technical points for spring management of apple orchards?
I. Orchard sanitation: In combination with winter pruning, saw off rotten and diseased dead branches, cut off branches with woolly apple aphid galls, and thoroughly clean the orchard. Clear away fallen leaves, dropped fruit, residual branches and rotting bark, then bury them in pits or burn them to reduce the source of pests and diseases. In late March, when the buds show green, spray to sanitize the orchard.

What are the control methods for apple tree root rot?
Apple trees often suffer from root rot. Because the root system is buried in the soil, when the disease is initially contracted or mild, it is either not discovered or, once discovered, not accurately diagnosed, so the right treatment is not applied. In mild cases this leads to weak tree vigor and reduced yield and quality; in severe cases it causes the death of the plant, or even the loss of the entire orchard.

What are the control methods for apple silver leaf disease?
Apple silver leaf disease is distributed in all apple-producing areas of China, occurring mainly in the apple-producing areas along the old course of the Yellow River in Jiangsu, Anhui and Henan provinces, and rarely seen in other apple-producing areas. It is a devastating disease that, under suitable conditions, can cause the entire apple tree to die. [Identification
