Frequently Asked Questions after Cotton Sowing
Cotton is one of the most important raw materials in China's textile industry, and it has a wide planting area in our country. Cotton planting is mainly sowing, so cotton sowing is very important. Attention should be paid to the management after cotton sowing, otherwise all kinds of problems will appear, which will affect the growth and development of seeds and hinder germination. So what are the common problems after cotton is sown? The following editor will introduce it to you.
1. Lack of soil moisture
Cotton has a great demand for water after sowing, so we must pay attention to the water content of the soil after sowing. If there is a lack of soil moisture, it will cause great hindrance to the germination of cotton seeds. If the seed is light, it will delay the germination time, and if it is heavy, it will not germinate at all. Therefore, after sowing, the cotton fields with poor soil moisture and lack of water should be watered in time, and ditches can be opened around the sowing ditch. If the amount of water is insufficient, then it is necessary to suppress the soil after watering to improve the soil moisture.
2. Rain after sowing
Although sufficient water is needed for cotton seed germination, it should not be too much. Especially when it rains after sowing, if it is not dealt with in time, it can easily lead to soil consolidation and difficulty in topping soil after seed germination. Therefore, if it rains after sowing, it should be ploughed in time to loosen the soil, break the soil consolidation part, and promote the emergence of the top soil of the seedlings. If the soil covered after sowing is too thick, then we also need to remove the soil properly to help the seedlings unearthed. However, seedlings emerging from the soil should not be exposed to direct sunlight, so we should pay attention to keeping a small amount of wet soil when picking the soil.
3. Uneven emergence of seedlings
After cotton sowing, the management should be strengthened to wait for the seeds to germinate, and when the seedlings are unearthed, the appearance of the seedlings should be checked in time. Check whether after missing sowing, rotten seedlings and dead seedlings and other bad phenomena, if any, then it is necessary to promote budding and replanting work in time. For some seedling deficiency holes, healthy seedlings with the same growth need to be made up in time. When the seedling grows a true leaf, it is necessary to do a good job of transplanting seedlings and transplant them with soil as far as possible. However, it should be noted that when transplanting, pay attention to the planting density, ensure that there is sufficient growth space, control the amount of water, avoid slow seedling time is too long, the phenomenon of strong bullying.
4. The weather is uncomfortable
After the cotton seedlings are unearthed, we should pay attention to observe the weather change, because the weather change is very great. If the temperature drops suddenly, it will pose a great threat to the growth of cotton. Therefore, when the temperature drops, we should pay attention to hoe the soil and increase the soil temperature. Then sprinkle plant ash evenly along the ridge to increase the temperature around the cotton plant. And under the condition of low temperature, the incidence of disease is relatively high, so we should properly spray carbendazim and other agents to avoid causing diseases and insect pests to affect the growth of cotton seedlings.
The above is a brief introduction to the common problems after cotton sowing. The management of cotton after sowing is very important and is closely related to its flowering and fruiting. So we must pay more attention to it! That's all for today's introduction. This article is for reference only. I hope it can be helpful to all of you.
