Detailed Explanation of Key Points of Water-Saving Irrigation Techniques for Citrus Planting
1. Straw mulching Straw mulching is a water-saving technique with abundant resources and obvious benefits, and it also has notable characteristics such as improving the soil and increasing fertility, conserving soil and water, and increasing yield. Cut the weeds in the citrus orchard, use the weed resources on the terrace walls, spread them in the tree, and then cover them with a thin layer of soil

Key Technical Points for Spring Production Management of Citrus
At present, it is the stage when citrus spring shoots are sprouting, which is also a period of the year when pests and diseases occur more frequently. The vigor of tree growth, the degree of pest and disease control, the level of yield, and the quality of fruit are all very directly related to the management during this period. Therefore, in production

Key Technical Points for Managing Young Citrus Trees for High Yield and Tree Shape
The management goal for young citrus trees is to promote multiple flushes of new shoots and the emergence of vigorous branches, accelerate the number of branching orders, form a full canopy as quickly as possible, and establish a strong framework, laying a good foundation for high and stable yields. To achieve this, the management technical measures should include: 1. Timely

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.

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.

A Detailed Explanation of Key Apple Tree Management Techniques in Midsummer
August is the peak period of flower bud differentiation and rapid fruit enlargement in apple trees, and also the peak period for the occurrence and development of pests and diseases; tree management during this period is very important, and the key management points are summer pruning, pest and disease control, topdressing, weeding and drainage.

Key Technical Points for Autumn Management of Young Apple Trees
Young apple trees have relatively strong growth vigor but poor cold resistance. With poor management, they are prone to shoot shriveling after overwintering. In mild cases, growth is poor, the tree shape becomes disordered, and fruiting is delayed. In severe cases, the entire tree dies, causing missing plants and affecting orchard establishment. If autumn field management is strengthened to promote robust tree growth and well-filled, mature branches, overwintering ability can be effectively enhanced and dehydration shriveling can be prevented. The main autumn management measures are introduced below.

Key Technical Points for Pollution-Free Apple Cultivation and Management
We fruit growers must recognize the current and future development direction of producing pollution-free apples. We should focus on applying organic fertilizer. The principles of applying organic fertilizer are: first, to increase the organic matter content of orchard soil; second, to combine organic fertilizer with inorganic fertilizer. We should control nitrogen, stabilize phosphorus, and increase potassium.
