Detailed Explanation of Peach Tree Shoot Control and Flower Promotion Methods and Technical Points
Many flower farmers who grow peach blossoms call to ask how to stop the growth of peach blossoms and form more flower buds? The main reason affecting flower bud differentiation is the contradiction between reproductive growth and vegetative growth. When vegetative growth is too vigorous, it will seriously affect reproductive growth, that is, flower bud differentiation. For this reason, during the flower bud differentiation period (late May to before leaf fall), attention must be paid to the balance between the two in order to ensure normal flower bud differentiation. 1. From late May to June, pinch off the tips at the 10-12 leaf position of the autumn shoots to promote flower bud differentiation and promote branching, or spray shoot-control agent. 2.

Detailed Explanation of Black Jujube Processing Methods and Technical Points
Black jujube is also processed from fresh jujubes. The technical points are as follows: 1. Raw material selection: Choose large fruits with small pits, thick and loose flesh, and low juice content, using fresh mature fruits as raw materials, and remove broken and rotten jujubes. 2. Grading: Separate and process according to fruit size, maturity, and variety. 3. Blanching: Put water in a pot and bring to a boil, add fresh jujubes and heat for 5-10 minutes. After boiling until the flesh is slightly soft, take them out to dry, and prepare for smoking. 4. Smoking preparation: Dig a pit underground 180 cm deep,

What are the control methods for jujube fruit shrinkage disease?
1. Symptoms: When jujube fruit shrinkage disease occurs, a pale yellow halo (ring) first appears on the shoulder or waist of the fruit, gradually expanding into irregular sunken lesions; the peel becomes water-soaked and infiltrated, with scattered needle-like round brown dots, and the flesh becomes earthy yellow, soft, spongy and necrotic; the fruit shrivels, tastes bitter, and is unfit to eat. 2. Disease pattern: Preliminary research has determined that jujube fruit shrinkage disease is a bacterial disease, and the pathogen mainly overwinters on fallen diseased fruit. It generally spreads and infects jujube fruit during the fruit coloring and ripening stage; the pathogen enters through fruit wounds via wind and rain or directly penetrates the peel.

Storage and Fresh-keeping Methods and Technical Key Points for Japanese Sansui Pears
Cultivars such as Hosui and Golden Pear have won wide popularity among consumers for their excellent flavor, so in recent years Japanese and Korean superior sand pears have made considerable progress in our country, and fruit output has also risen substantially year by year. However, the flesh of these pears is relatively soft, easily damaged during transport, and because their harvest period is short, their storability is poor, and their sales period is too concentrated, it is difficult to supply the market over the long term. How to store and keep them fresh is therefore particularly important. The author hereby introduces Japan's storage and fresh-keeping methods for Sansui pears to everyone for reference. 1. Harvest maturity and

Detailed Explanation of the Cultivation Methods and Key Techniques for the Dwarf Peach
The dwarf peach (Prunus persica var. densa Makino) is a deciduous small tree in the rose family (Rosaceae), genus Prunus, and a variety of the common peach. The plant is dwarf, with short internodes and dense flower buds. It begins its full blooming period in April, which lasts about half a month. The fruit ripens in September. The dwarf peach likes sunlight and well-drained soil, is drought-tolerant and relatively cold-tolerant, and overwinters at above 1°C. The dwarf peach is naturally vigorous, and it is enough to pay attention to two steps: fertilizing and thinning flowers. Generally, base fertilizer is applied in winter after the leaves fall. Before the flowers and leaves sprout in spring, a comprehensive liquid fertilizer mainly of phosphorus and potassium is applied; after the flowers fade, a phosphorus-potassium fertilizer is applied once, and thereafter a relatively dilute phosphorus-potassium fertilizer solution is applied about once every half a month. Fertilizing is stopped in summer, and after September a comprehensive fertilizer solution is applied twice. After the flowers open, besides keeping some flowers with good growth and good positions, thinning out the useless flowers is the key to the dwarf peach bearing fine fruit.

What are the control methods for the pear bicolor aphid pest?
This insect, commonly known as the pear aphid, is a major pest of pear trees and is found in all pear-growing regions. After pear trees are infested, large numbers of leaves curl up, causing early defoliation, weakening of tree vigor, and impaired fruit development, seriously affecting yield and quality. [Occurrence pattern] About 10 or more generations occur per year. Overwintering eggs generally hatch in March and late March when pear buds swell and open. After the young aphids grow, they continuously give live birth to new young aphids. By late April, winged aphids begin to appear. During May, winged aphids form in large numbers and migrate to weeds to reproduce and cause damage. In October, winged aphids migrate back to pear trees

How to identify and control jujube witches' broom? The methods explained clearly in one article
Jujube witches' broom, commonly known as "male jujube tree", is a devastating disease of jujube trees. In severe cases, it can cause mass death of jujube trees and even destroy the entire orchard. 1. Symptom identification (1) The initial symptoms appear after flowering, manifested as degeneration of floral organs and abnormal sprouting of buds; the leaves that grow out are narrow and small, forming clustered branches and leaves, and the young leaves show vein clearing, yellowing and curling into a spoon shape. (2) The leaves of diseased trees show obvious pathological changes after flowering: first the mesophyll turns yellow, then gradually the entire leaf yellows, the edges curl upward, and later the leaves become hard and brittle, dull and lusterless. (3) On the current-year vegetative shoots of diseased plants, the normal buds and

What methods are there to extend the storage and freshness period of fresh-eating jujubes?
Jujubes contain a variety of trace elements and abundant nutrients, and have unique nutritional and medicinal value. However, after fresh jujubes are harvested and stored under natural conditions, they have only a few days of crisp freshness, and the flesh quickly turns brown and softens. After several years of experimental research, the author believes that to extend the storage and freshness period of fresh-eating jujubes, the following key techniques must be grasped: 1. Select storage-tolerant varieties. Generally speaking, late-maturing varieties are more storage-tolerant than early-maturing varieties, and dual-purpose varieties have better storage tolerance than fresh-eating varieties. At present, the quality and storage tolerance of Dongzao among fresh-eating jujubes

A Detailed Guide to Jujube Fruit Storage Methods: Easily Extend the Fresh-Keeping Period
I. Timely Harvesting Jujube fruit maturity is one of the important factors affecting the fresh-keeping effect of fresh jujube storage. Many studies have shown that jujube fruit maturity is negatively correlated with storage performance: the lower the maturity, the more storage-tolerant it is, and its storage tolerance declines with jujube fruit maturity. White-ripe fruit is better than early-red fruit, early-red fruit is better than half-red fruit, and the storage tolerance of fully red jujube fruit declines noticeably. In 1985, the storage performance at different harvest times at the Fruit Tree Research Institute of the Shanxi Academy of Agricultural Sciences showed that for pointed jujubes picked from the same tree at different maturity stages and stored in a cold store at 0°C±1°C
