How to manage cotton during the bud stage? The latest field management key points

Cotton is a major textile crop in our country and is widely used in various textile product industries. It has a very large planting area in our country, and when growing cotton there are many different growth stages. Different growth stages of cotton have different management key points, and management work is especially important during the cotton bud stage. So below, the editor brings you the key points of cotton field management. Let's take a look together!

1. Timely pruning

The branches and leaves of cotton are relatively lush. During the cotton bud stage, if the branches and leaves are too lush and grow excessively, it will cause excessive consumption of nutrients. This makes the cotton field too closed and reduces permeability, affecting cotton growth. So we must do a good job of pruning in time. Generally, when cotton buds appear, the branches, leaves and excess tiller buds below the fruiting branch node should be removed. But on cotton plants in missing-plant areas, we should keep about 3 branches and leaves. Then when they grow about 6 leaf branches, the terminal buds should be removed in time to promote flowering and fruiting and increase yield.

2. Reasonable fertilization

The fertilizer demand of cotton during the bud stage is moderate, but attention should be paid to the nutrient ratio in the fertilizer. Do not apply too much nitrogen fertilizer, because if nitrogen fertilizer is excessive, it can easily cause excessive growth of cotton, consume too many nutrients, and cause undesirable phenomena such as cotton boll shedding. However, a certain amount of nitrogen fertilizer is also needed. If insufficient, cotton plants will not develop enough and yield will decline. Therefore, for some cotton seedlings with sufficient fertility and strong growth, we should apply little or no nitrogen fertilizer. On the contrary, soil with poor fertility needs more nitrogen fertilizer. Fertilization time should be controlled at the full bud stage, avoiding simultaneous water and fertilizer work, which reduces fertilization effect.

3. Intertillage and weeding

Intertillage and weeding are greatly related to cotton growth, yield and so on. Especially during the cotton bud stage, reasonable intertillage work can promote the downward growth of the cotton plant's roots. This is beneficial for cotton's nutrient and water absorption and improves cotton growth ability. Weeding is to prevent weeds from competing for cotton's growth nutrients so that nutrients are concentrated in the cotton plants. After each intertillage, attention should also be paid to earthing up to improve the soil's heat preservation ability, avoid cotton plant lodging, and prevent soil erosion. During the rainy season, intertillage should also be combined with drainage work to prevent waterlogging damage.

4. Pest and disease control

Pests and diseases can threaten various parts of the cotton plant such as branches, leaves and fruits, causing a sharp decline in cotton yield and seriously affecting cotton yield. Therefore, during the bud stage, we should follow prevention and control standards and use pesticides reasonably during the control period. The main targets of pesticide use are mirids, Fusarium wilt and so on. Do the basic work well and strengthen management in all aspects. Observe growth conditions frequently, and when abnormal conditions are found, check in time. Do not use pesticides blindly, to avoid improper pesticide use causing phytotoxicity.

The above is a brief introduction to the key points of field management during the cotton bud stage. No matter which growth stage cotton is in, field management is very important. Because it is directly related to yield and cotton quality, everyone must pay much attention. That is all for today's introduction.
