Insect-resistant cotton is the key to high yield to prevent premature aging

In recent years, the widespread adoption of insect-resistant cotton has led to a growing issue: premature aging. Compared to non-insect-resistant varieties, insect-resistant cotton is more prone to early senescence. This phenomenon can be attributed to several factors. First, while insect-resistant cotton effectively controls bollworm infestations, it reduces the loss of buds and bolls, leading to vigorous reproductive growth. This results in an earlier and higher number of bolls, which consumes a significant amount of nutrients from the plant, increasing the risk of premature aging. Second, the introduction of insect-resistant genes may weaken the plant’s natural resistance to other diseases, further contributing to early decline. Soil fertility and fertilization also play a crucial role in this issue. Insect-resistant cotton requires richer soil and more balanced fertilization to maintain its health. To prevent premature aging, farmers must address these underlying causes through targeted management strategies. One effective approach is crop rotation, which helps improve soil structure, enhance fertility, and reduce disease pressure. Incorporating organic fertilizers and returning straw to the field can further boost soil quality, helping the plants better withstand environmental stress. Another important practice is early bud removal. By removing 4–8 early buds from the lower branches in mid-June, farmers can balance vegetative and reproductive growth, reducing the risk of premature aging. Field trials in Weifang over four years showed that this technique significantly reduced buds and deadlocks, improved fiber quality, and increased yield and income. Proper irrigation is also essential. During the bud stage, timely watering ensures adequate nutrient uptake, especially for nitrogen. Farmers often say that “cotton watered before and after wheat harvest will never be worse than others.” Keeping the soil moist during critical growth stages helps prevent stress-related aging. During the flowering and bolling phase, maintaining proper moisture and applying compound fertilizer at 15–20 kg per acre supports the plant’s high demand for nutrients. Foliar sprays of NPK solution 2–3 times between late July and early August can further enhance yield and delay aging. Water management is equally important. During dry spells, timely irrigation is necessary, while during rainy periods, drainage should be ensured to prevent root asphyxiation from waterlogging. Protecting the roots and leaves is another key strategy. Once the plant enters the mid-fruiting stage, careful handling is needed to avoid damaging the roots. Avoiding deep cultivation after flowering helps maintain leaf function and prevents early decline. Finally, using pesticides wisely is crucial. Diseases like red spider mites and stem blight often occur later in the season. Overuse of chemicals can harm leaves and accelerate aging. Instead, farmers should prioritize natural pest control, use low-toxicity pesticides, and avoid high concentrations to protect leaf health and extend the functional life of the plant. By implementing these practices, farmers can effectively manage the challenges of insect-resistant cotton and ensure a successful harvest.
