How to prune fig trees in winter? Detailed explanation of pruning methods
According to the characteristics of figs, which have fewer shoots and strong growth vigor, during the formative pruning period of young trees, in order to rapidly increase the number of branches, expand the canopy, promote flower formation, and bear fruit early, the pruning amount should be appropriately light; later, as the tree age increases, the number of twigs gradually increases, and growth

Reasons for Low Fruit Set in Muskmelon and Methods to Improve It
I. Reasons Why Plants Are Prone to Poor Fruit Set 1. Excessive vegetative growth or weak, spindly plants. During the growing period of muskmelon, applying too much nitrogen fertilizer or cultivating in a protected environment with high temperature and high humidity and poor ventilation prevents vegetative growth and reproductive growth from being coordinated, often resulting in excessive vegetative growth or weak, spindly plants.

What are the causes of melon fruit abortion and the control methods?
1. Causes of fruit abortion 1. Temperature too high or too low. When the temperature is too high, photosynthetic accumulation is low and respiration consumption is high, which easily causes the vines to grow excessively, leading to malnutrition and fruit abortion; when the temperature is too low, the root absorption capacity weakens, affecting photosynthesis and leading to nutrient deficiency and fruit abortion. 2. Soil too dry

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>

Methods for preventing and treating Fusarium wilt in melons, a must-read for growers
Symptoms This disease can occur throughout the entire growth period of melons. When seedlings are infected, the leaves of the diseased seedlings become lighter in color, gradually wilt, and finally die. When the stem is cut open, the vascular bundles can be seen to have discolored. When the disease occurs during the mature plant stage, the leaves of the plant wilt and droop from bottom to top, some leaf edges turn brown or produce brown necrotic

What are the control methods for the tea bagworm on pomegranate trees?
1. Manual control Manually remove the bagworm bags hanging on the branches and destroy them in a centralized manner. It is more convenient to do this during the dormancy period of the fruit tree, but care should be taken to protect natural enemies. This method has a thorough control effect and is safe for pomegranates, but if the orchard area is large, it is time-consuming and labor-intensive. 2. Chemical control

What are the shaping and pruning methods for pomegranate trees?
Strong sprouting ability of latent buds and high tolerance to pruning are the greatest characteristics of pomegranate. This creates favorable conditions for shaping, but the shortcoming is that its branches sprout readily, the tree shape easily becomes messy, and this affects ornamentation. To make pomegranate produce more flowers, more fruit, and beautiful form, it is necessary
