Latest Analysis of Common Problems After Cotton Sowing
Cotton is one of the most important raw materials for our country's textile industry, and it is widely planted in our country. Cotton cultivation is mostly done by sowing, so cotton sowing is very important. After cotton sowing, attention must be paid to good management work; otherwise, various problems will appear, affecting seed growth and development and causing germination to be blocked. So what common problems occur after cotton sowing? Below, the editor will introduce them to everyone!
1. Insufficient soil moisture
After cotton is sown, its demand for water is relatively large, so after sowing we must pay attention to the soil's water content. If there is insufficient soil moisture, it will cause great obstacles to cotton seed germination. In mild cases, it delays seed germination time; in severe cases, it can prevent germination altogether. Therefore, after sowing, cotton fields with poor soil moisture and water shortage should be watered in time. Water can be applied by making furrows around the sowing furrow. If the amount of water applied is insufficient, then after watering, the soil also needs to be compacted to improve soil moisture.
2. Rain after sowing
Although cotton seed germination needs sufficient water, water should not be excessive. Especially if it rains after sowing and it is not dealt with in time, it can very easily cause soil crusting, making it difficult for germinated seeds to push through the soil. Therefore, if it rains after sowing, intertillage and loosening of the soil should be carried out in time to break up crusted areas of soil and promote seedlings pushing through the soil and emerging. If the soil covering after sowing is too thick, then we also need to appropriately scrape away some soil to help seedlings emerge. However, seedlings that emerge after scraping away soil must not be exposed to direct sunlight, so when scraping away soil, care should be taken to retain a small amount of moist soil.
3. Uneven emergence
After cotton sowing, management should be strengthened while waiting for seeds to germinate and emerge. When seedlings emerge, the emergence situation should be checked in time. Check whether there are adverse phenomena such as missed sowing, rotten seedlings and dead seedlings. If there are, then work to promote germination and reseed should be carried out in time. For some missing seedling holes, healthy seedlings of the same growth should be supplemented in time. When seedlings grow one true leaf, transplanting work should be done well, and soil should be kept around the roots for transplanting as much as possible. However, it should be noted that when transplanting, pay attention to planting density, ensure sufficient growth space, and control the amount of watering well to avoid an overly long recovery period and the phenomenon of the strong bullying the weak.
4. Unsuitable weather
After cotton seedlings emerge, pay attention to observing weather changes, because weather changes can be very great. If the temperature drops suddenly, it will pose a great threat to cotton growth. Therefore, when the temperature drops, pay attention to hoeing the soil to increase soil temperature. Then evenly sprinkle plant ash along the ridges to increase the temperature around the cotton plants. In addition, under low-temperature conditions, the incidence of disease is relatively high, so we should also appropriately spray agents such as carbendazim to avoid triggering pests and diseases that affect the growth of cotton seedlings.
The above is a brief introduction to common problems after cotton sowing. Management work after cotton sowing is very important and is closely related to flowering and fruiting. Therefore, everyone must pay close attention! That is all for today's introduction. This article is for reference only, and we hope it can be helpful to everyone.
