Control Methods for Penicillium Mold and Green Mold in Pomelo
Symptom characteristics: mainly affects fruit after harvest during storage and transport. The symptoms of the two diseases are similar, mostly starting from the stem end or wounds, initially appearing as light brown water-soaked spots. The lesions expand rapidly, the fruit softens and rots, and a layer of white mold grows on the lesion surface; later the white mold patches turn into green mold patches.

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

What are the improved methods for pear tree cultivation?
For pear trees with poor quality and low yield, the usual method is to cut down the original plants. Planting improved, vigorous seedlings for renewal means it takes five years before they come into production. If the top-grafting and variety-change technique is used, however, the original tree framework can be utilised to rapidly form a canopy, achieving a per-tree yield of

Detailed Explanation of Rapid Propagation Methods for Cherry Seedlings
1. Land preparation and seedbed making In mid-to-late April, select well-drained sandy loam soil, apply 2000-3000 kg of high-quality farmyard manure per 667 sq m (1 mu), deep plow, level and harrow fine. Then make beds, bed width 1 m, length 15-20 m, and use a 200-fold ferrous sulfate solution for soil disinfection

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

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.

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
