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.

Detailed Explanation of Key Cultivation Techniques for Newly Established Citrus Orchards
1. Orchard establishment should be of high quality and started early. The key points are digging the trenches well and applying sufficient basal fertilizer, passing the first hurdle of orchard establishment well. Dig continuous trenches 1 m wide and 0.6 m deep along the contour lines, fill each mu with 2500--30000 kg of green manure, and apply an appropriate amount of nitrogen and phosphorus fertilizer; next: for low-lying land and paddy fields, drainage ditches should be dug well, with the main drainage ditch more than 0.80 m deep, to reduce field humidity and lessen pest and disease damage. Orchard establishment should begin promptly after the autumn harvest to ensure enough time for the green manure and soil to decompose fully; field-grown seedlings are best planted before late October (mid-March in spring), while container seedlings should be planted earlier, before October (after March in spring); planting time should be early rather than late.

What are the key points of autumn management techniques for plum orchards?
Autumn is an important period for plum trees to restore tree vigor and accumulate nutrients in the tree body. Applying scientific management measures can increase the reserve of tree nutrients, promote further differentiation of flower buds, and lay a good foundation for high yield and high quality in the following year. Through many years of practice, whenever the management techniques of this period

How to apply sufficient base fertilizer when planting plum trees
Currently most plum orchards have less than 1% organic matter, and some plum orchards are even below 0.5%, far below the requirements of high-quality, high-yield orchards, so the amount of base fertilizer must be increased. If the dual needs of tree growth and soil improvement are taken into account at the same time, the application rate of organic fertilizer

Key Technical Points for Soil Management in Schisandra (Five-Flavor Berry) Orchards
In nature, soil is the foundation for plant growth and fruiting, and the source of water and nutrient supply. When the soil is deep, loose in texture, and well aerated, soil microorganisms are active and can improve soil fertility, which in turn favors root growth and enhances metabolism,

Detailed Explanation of Key Points of Autumn Fertilization Techniques in Apple Orchards
1. Fertilization principles: On the premise of increasing the application of organic fertilizer and building up soil fertility, emphasize potassium, increase nitrogen, stabilize phosphorus, and supplement micronutrients, and vigorously promote soil-testing-based formula fertilization. 2. Fertilization types: (1) Organic fertilizers mainly include: manure and urine, barnyard manure, compost, cake fertilizer, straw,

Detailed Explanation of Key Technical Points for Soil, Fertilizer and Water Management in Apple Orchards
1. Soil management For the soil management of mature fruit tree orchards, the clear-root method or tree-disk mulching method should be adopted. From spring to before the rainy season each year, after combining fertilization and irrigation, carry out intertillage and loosening of the soil. Weed 1-2 times to keep the soil loose and free of weed growth. In the rainy season, cut grass and cover the tree disk 1-2 times. In autumn, after the fruit trees shed their leaves, carry out autumn plowing. Use an iron shovel to deep-turn the tree disk to 15-20 cm, then apply additional organic fertilizer. Apply topdressing three times, respectively before and after sprouting, after flower drop, and during the fruit enlargement stage, using nitrogen, phosphorus and potassium elements in combination. The ratio is 1:0.6:1.5.

How can fertilizer use efficiency in apple orchards be improved?
1. Increase soil organic matter content. Soil organic matter content is an important indicator for measuring the soil fertility of an orchard, and it is also a basic condition for producing pollution-free fruit. Soil organic matter can promote the formation of soil aggregate structure, increase soil aeration, and improve the soil's

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.
