When choosing cotton varieties, it's essential to select high-quality plots that are free from pests and diseases. Focus on the central Piaotao plants and choose ripe "dried flowers" for better quality. Here are some important considerations:
Avoid hybrid cotton varieties, as current technology makes it difficult to maintain their purity. The F2 generation of hybrids often shows significant genetic instability, which can lead to poor performance in the next growing season.
Do not select cotton plants that are early or late-season peaches with poor growth, low boll weight, or weak seed germination. These plants tend to be less vigorous and may not produce reliable yields.
Avoid using cotton seeds that have been "split" or picked while still wet. Some growers mistakenly harvest immature flowers, which haven't fully developed and lack the necessary post-maturity processes. Such seeds are unlikely to germinate properly.
Cotton is a cross-pollinated crop with an outcrossing rate between 3% and 20%. Over time, if not properly maintained, insect-resistant varieties can become contaminated due to pollination by other cotton types. Therefore, avoid planting seeds from plots with low purity or severe degradation.
Never use cotton plants that are heavily infected with wilt or Verticillium wilt. These diseases are persistent and can spread through seeds, affecting future crops. However, if a plant shows strong resistance despite disease pressure, it may still be worth keeping.
Avoid drying cotton seeds on cement floors, as this can cause them to lose moisture too quickly and reduce their viability. Seeds with high moisture content should be dried properly to ensure good germination.
Also, do not store cotton seeds alongside pesticides or fertilizers. Poor ventilation in storage areas can expose seeds to harmful gases, significantly reducing their germination rate over time. Always keep seeds in clean, dry, and well-ventilated spaces.
Anti-Ulcerative
Ulcers is commonly known as gastric ulcer and duodenal ulcer, the formation of ulcers is closely related with gastric acid or pepsin digestion. Ulcer disease is a chronic disease, its seizures were cyclical, episodes and remission of alternating appear, and the onset of abdominal pain has a certain rule. The main cause of ulcers include: 1. Helicobacter pylori infection 2. Bad diet 3. Mental factors 4. Drug stimulation. Many patients with gastric ulcer who have taken non-steroidal anti-inflammatory drug history, these drugs will stimulate our gastric mucosa, causing damage, then it will cause ulcer disease over time. The current anti-ulcer drug is mainly focused on reducing gastric acid and enhance the protective effect of gastric mucosa. In recent years,the research and development of anti-ulcer drug progress is faster, effective drugs have been listed, sales are also rising.
