Detailed Guide to Licorice Planting Methods and Cultivation Experience
1. Site selection and land preparation. Usually choose sandy loam soil that is fertile, loose in texture, well-drained, and low in salinity and alkalinity. Usually when preparing the land, a tractor is used to plow the field, with deep plowing of about 20 cm. At the same time, apply 2000-2500 kg of barnyard manure per 667 sq m as base fertilizer, then level and harrow finely.

Detailed Explanation of Licorice Propagation Methods and Cultivation Techniques
Licorice propagation has three methods: seed propagation, rhizome propagation and division propagation. 1. Site selection and land preparation: Sandy soil and loose red loam soil are suitable; apply 2500 kg of farmyard manure per 667 sq m, deep plow 40-50 cm in autumn, harrow fine and level, and make high ridges 40-50 cm wide with furrows 30-35 cm wide.

Control Methods and Technical Key Points for Apple Little Leaf Disease
Apple little leaf disease occurs mostly in orchards with poor soil and good permeability. Because of low zinc content, soluble zinc salts leach away and the disease becomes severe; frequent watering and rainfall cause large losses of soluble zinc; excessive nitrogen fertilizer use increases the tree's zinc requirement; in saline-alkali soil the pH

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,

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.

Control Methods for Mango Fruit-piercing Moth Pests and Diseases
I. Damage. The more serious pests include the fruit-piercing moth (Oraesia emarginata), the bird-beak fruit-piercing moth, the dead-leaf fruit-piercing moth, and the super-bridge fruit-piercing moth. The adult moths use their sharp mouthparts to pierce into the fruit and suck the juice of the flesh, causing the fruit to drop. Fruit pierced before harvest will rot during storage and transport. II. Morphological characteristics.

Methods for controlling thrips pests and diseases in mango cultivation
Classification: Thysanoptera, family Thripidae. I. Tea yellow thrips Scirtothrips dorsalis Hood 1. Damage: Adults and nymphs damage mango leaves, causing them to appear scalded by hot water and eventually wilt; they damage fruit, causing brown rough spots on the surface. This insect also damages tea plants, bananas

Control methods for the mango shoot borer (Chlumetia transversa) pest and disease
(1) Damage Also called the shoot borer. It occurs commonly in mango-producing areas and is an important pest of mango. The larvae bore into and feed on young shoots and flower spikes; infested young shoots or flower spikes wither or grow weakly. (2) Morphological characteristics Adult body length 11mm, wingspan 23mm. The dorsal side of the body is dark brown, the ventral side grayish white

Control Methods for Mango Sooty Mold and Algal Leaf Spot
(1) Mango sooty mold: 1. Symptoms: This disease mainly occurs on leaves and fruit. A layer of black fuzzy material covers the surface of leaves and fruit, resembling soot, hence the name sooty mold. In severe cases, the entire leaf and fruit are covered by mycelium (soot). This type of

Detailed Explanation of Summer Pruning Methods and Techniques for Jujube Trees
Traditional jujube orchard management is relatively extensive, and summer pruning is generally not carried out, resulting in disordered tree shape and small angles of scaffold branches. Although the tree is tall, ventilation and light penetration are poor, and yield is low. Summer pruning of jujube trees not only facilitates ventilation and light penetration, but also regulates tree nutrition and increases fruit set
