Key Technical Points for Winter Management of Persimmon Orchards
In winter, the management work of a persimmon orchard has three key points, namely increasing fertilizer, pruning, and cleaning the orchard. Increasing fertilizer and improving the soil. The persimmon tree is a deep-rooted tree species, and only by expanding the planting holes, improving the soil, and applying more fertilizer can the tree grow vigorously. Bearing persimmon trees should have their holes expanded and soil improved in winter, with holes 1-1.5 m long, 0.4 m wide, and 0.4-0.5 m deep. When backfilling with topsoil, apply 100-150 kg of farmyard manure per tree, or 50 kg of dried pig or cattle manure, or 100-150 kg of mushroom soil, or 1-1.5 kg of calcium magnesium phosphate fertilizer, etc., mix evenly with the topsoil, and fill it into the lower layer. Level the surface of the hole with topsoil from the orchard. Deep digging to improve the soil can also be used, that is, spreading organic fertilizer evenly at the drip line of the canopy, and then deep digging 20 cm at the fibrous root zone.

Management Methods and Technical Key Points After the Persimmon Tree Fruits
Timely fertilization: When the fruit's transverse diameter reaches 4~5 cm and when the fruit size has basically become fixed, apply fruit-swelling fertilizer and pre-harvest fertilizer, mainly with quick-acting, quick-dissolving nitrogen-phosphorus-potassium fertilizer. For fruiting trees over five years old, apply 1.5~2 kg of urea and 0.75~1 kg of monopotassium phosphate per tree, or apply nitrogen-phosphorus-potassium

How to Cultivate Blackberries with High Quality and Scientific Methods? Detailed Explanation of Key Technical Points
1 Site Selection The most suitable soil texture for a blackberry orchard is loam or sandy loam. Soil pH can range from 5.0 to 8.0, but 6.0 to 6.5 is best. Soil salt content should be <0.1%, soil layer thickness should preferably be >50cm, and the groundwater level should be >100cm. For most blackberry varieties, the minimum winter temperature needs to be above -15 degrees Celsius

Key Technical Points for Summer Training and Pruning Management of Pear Trees
The training and pruning of pear trees is an important measure in cultivation management, and also a very meticulous task. Training is based on the pear tree's growth and fruiting habits, growth and development patterns, site conditions, and other cultivation management characteristics. Pruning, on the basis of training, continues

Key Technical Points for High-Quality, High-Yield Cultivation of Sweet Cherry
Sweet cherry, also known as large cherry, was introduced to Yantai from Korea by sea and to Xinjiang from Russia by land between 1880 and 1890, and has a cultivation history of more than one hundred years. In Shandong, sweet cherry is concentrated in Yantai, Qingdao, Weihai, Tai'an and Linyi

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.

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.

Clean the field. After the crop is harvested, weeds and residues should be removed promptly. During the melon growing period, weed promptly, remove diseased leaves, and take weeds, residues, and diseased leaves outside the field to be burned in a centralized manner.</p><p>3. 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
