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.

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.

How to Achieve Full Seedling Emergence in a Single Sowing of Cotton? Key Technical Points Explained
1. Variety selection: Choose hybrid varieties with high yield, good quality, great potential and strong stress resistance, such as Hanza 429 and Hanza 301; or use conventional varieties such as Ji 228 and Han 7860. 2. Seed treatment: This includes sunning the seeds before sowing and germination testing. Sun the seeds for 3-5 days before sowing to promote after-ripening, so as to improve the seed germination rate and germination vigor. Do not sun the seeds on concrete or asphalt surfaces. Randomly take 100 or 200 seeds and carry out a germination rate test to determine the sowing rate.
