Key Technical Points for Pollution-Free Apple Cultivation and Management
We fruit growers must recognize the current and future development direction of producing pollution-free apples. We should focus on applying organic fertilizer. The principles of applying organic fertilizer are: first, to increase the organic matter content of orchard soil; second, to combine organic fertilizer with inorganic fertilizer. We should control nitrogen, stabilize phosphorus, and increase potassium.

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

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.

Detailed Explanation of Key Techniques for Autumn Management of Apple Trees
The peak period of flower bud differentiation in apple trees occurs in autumn. Doing a good job of autumn management of apple trees can lay a solid foundation for high, stable and high-quality yields in the following year. Fertilizer and water management For non-bearing trees, 0.15-0.25 kg of diammonium phosphate can be applied per tree; for large bearing trees, according to the planned yield for the following year, 0.7 kg of pure nitrogen and 0.7 kg of available phosphorus can be applied per 100 kg of fruit. Topdressing for young trees can significantly increase the sprouting rate in the following year. For large trees in full bearing period, applying fertilizer in autumn year after year, under the same amount and types of fertilizer, compared with topdressing in early summer, can increase the yield by about 50 kg per tree.

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,

What are the control methods for apple fruit cracking disease?
In the late stage of apple growth, fruit cracking disease is common and causes relatively serious damage, severely affecting the commercial value of apples and deserving sufficient attention. Apple fruit cracking disease is caused by slow expansion of fruit flesh cells during the early drought period of apple growth, and rapid cell expansion when rain occurs in the middle and late stages of apple growth

How should licorice be grown to achieve high yield?
I. Seedling raising and transplanting 1. Seedling raising The seedling bed should be selected from plots of humus soil or sandy loam soil with deep, fertile and loose soil. Apply 2000 kg of farmyard manure, 25 kg of superphosphate and 10 kg of potassium sulfate per mu as base fertilizer, plow more than 40 cm deep, level and harrow fine, and make 110 cm

Key Field Management Techniques for Licorice Cultivation
1. Licorice begins to emerge about 15 days after planting. After the seedlings are established, apply 15 kg of urea per mu along with irrigation to promote seedling growth. From late May to early June, open furrows and apply 30 kg of diammonium phosphate per mu, then irrigate. During this period, fertilize and irrigate scientifically to ensure vigorous seedling growth

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.
