Key Technical Points for Summer Training and Pruning of Cherry Trees
Pinching is the most widely used method in summer pruning of cherry trees; it refers to removing the tender shoot tip before the new shoot has become lignified. Pinching young trees encourages more shoots to sprout, lowers the position where shoots emerge, rapidly increases the number of branches and leaves, expands the canopy, reduces ineffective growth, and promotes flower bud formation.

Technical measures to promote fruit set in pomegranate cultivation
The flowers of the pomegranate are bisexual and, depending on the degree of pistil development, are divided into complete flowers and incomplete flowers. Complete flowers are gourd-shaped or tubular flowers, commonly known as "big-bottomed fruit flowers", and are the main part that sets fruit; incomplete flowers have a trumpet-shaped calyx tube and are called "bell-shaped flowers" or "pointed-bottomed false flowers".

Methods and Technical Key Points for Controlling Powdery Mildew in Melons
1. Select disease-resistant varieties. There are obvious differences in disease resistance among different melon varieties, so selecting disease-resistant varieties is the key to controlling the degree of disease occurrence. 2. Clean the field. After the crop is harvested, weeds and residues should be removed promptly. During the melon growing period, weed promptly, remove ⟦4 <p>1. Select disease-resistant varieties.

Scientific management to enhance plant disease resistance. Apply sufficient basal fertilizer, especially heavily apply decomposed organic fertilizer, and plow deeply and harrow finely; prevent excessive vegetative growth and premature senescence of plants, organize branches and vines promptly, and strengthen ventilation and light penetration; during the mid-growth stage, pay attention to topdressing phosphorus and potassium fertilizers, and use foliar fertilizer well to cultivate strong branches and vines and enhance the disease resistance of the population.</p><p>4. Scientific irrigation. Create environmental conditions suitable for melon growth but unfavorable for the occurrence and development of powdery mildew. Irrigation should follow 4 principles: do not water on cloudy days but water on sunny days, do not water in the afternoon but water in the morning, do not water heavily but water lightly, do not water on the surface but water under the surface (that is, subsurface irrigation under film).</p><p>5. Chemical control. Use 15% triadimefon wettable powder at 1000-1500 times dilution, or 40% Daconil suspension concentrate at 800-1000 times dilution, or 40% Fuxing emulsifiable concentrate at 6000 times dilution, or 10% Shigao water-dispersible granules at 2000 times dilution, or 30% Tefuling wettable powder at 5000 times dilution, or 50% thiophanate-methyl wettable powder at 1000 times dilution, etc., alternating sprays for control, spraying once every 7-10 days, for 2-3 consecutive sprays. Medication is prohibited 7 days before melon harvest to allow safe harvesting.</p>

Key Technical Points for Greenhouse Management of Muskmelon After Transplanting
1. Greenhouse temperature regulation After transplanting, in the early stage, in order to raise the greenhouse temperature and promote seedling recovery, the greenhouse film should be fastened tightly, and the straw mats should be uncovered and covered in a timely manner; before flowering and fruit setting, the daytime greenhouse temperature should be maintained at 25-28°C, and at night at 16-18°C. When the greenhouse temperature exceeds 28°C, the greenhouse film should be opened for ventilation. As the plants grow

High-yield Cultivation Measures and Technical Points for Melons
I. Sowing Period For spring protected cultivation, the temperature inside the greenhouse should be stable above 10°C at transplanting time; counting back 30-35 days from this point is the optimal sowing period. II. Raising Strong Seedlings 1. Preparation of nutrient soil: decomposed barnyard manure, horse manure (or chicken manure), and sieved field topsoil, in a ratio of 3:2:

Key Technical Points for the Prevention and Control of Apple Pests and Diseases in the Mid-to-Late Stage
The young fruit stage is the peak infection period of early defoliation disease, the initial stage of branch ring rot, and also the peak damage period of aphids, leaf mites and scale insects. Therefore, doing a good job in the prevention and control of apple pests and diseases during the young fruit stage is crucial for strengthening tree vigor, improving fruit quality and achieving increased

What are the technical measures for flower and fruit retention in mango?
The flowering and fruit-setting period of mango is an extremely critical period in mango production management. The management measures during the flowering and fruit-setting period include the following aspects: 1. Training of flowering shoots. About 2 months before flower bud differentiation, remove overly dense branches, shaded weak branches and diseased and pest-infested branches, leaving only 1-2 shoots per branch, which can increase the light penetration of the canopy, help concentrate nutrients and create good ventilation and light conditions, promote flower bud differentiation and prevent the occurrence of pests and diseases.

Control Methods and Technical Key Points for Mango Shoot Blight and Gummosis
Mango shoot blight and gummosis mainly damages branches and the main trunk, causing dieback, but it can also harm seedlings and fruit. When seedlings are affected, dark brown necrotic spots usually appear from the bud graft point or wounds, rapidly spreading upward and downward, causing the scion to die. When the main trunk or branches are affected, the cortex

Methods for Preventing and Controlling Pests and Diseases of Winter Jujube Trees in Autumn and Winter, and Key Technical Points
After the beginning of autumn, winter jujube trees gradually enter the dormant period, and their tolerance to chemicals is relatively high. As temperatures drop, pests and diseases enter bark cracks, scars, branch forks, fallen leaves, fallen fruit, mummified fruit or the soil, where they lurk to overwinter. Therefore, it is necessary to seize the favorable opportunity for pest and disease control in autumn and winter,
