Why do crops burn seedlings and reduce yield after irrigation? How to solve it?

Generally speaking, the growth of crops is inseparable from water, and even before the crops are planted, it is necessary to consider whether the soil moisture is suitable for germination and emergence. For example, there are two modes of wheat planting in our local area, one is to increase soil moisture by flood irrigation, and then start rotary tillage sowing after drying for two days and other matters related to agricultural machinery operations, and the other is to sow seeds in time while looking at soil moisture, so that the wheat can be watered immediately after germination, and it can be both solid and watered to meet the needs of wheat growth.

<> if a crop wilts due to drought during the sowing process, the best solution is to irrigate it in time. Timely irrigation of crops is very beneficial to alleviate the drought of crops, not only will there be no problem of dead seedlings, but also can change the growth state of crops in a short period of time, and improve the growth vitality of crop seedlings. But there is a situation where it is a good way to replenish water in time, including fertility, but manure that is not fermented well is a disaster for crops.

First, there are many miscellaneous bacteria in the manure that has not been well fermented, which is easy to cause crop root diseases. In addition, the manure that has not been fermented and matured will be fermented in the soil for a second time, and a large amount of heat will be generated during the fermentation process, causing the crop to burn seedlings, and at the same time, a large amount of ammonia will be produced, causing the crop leaves to turn yellow.

In particular, the recent rain is relatively sufficient, the manure fermentation is more severe, and the corn seedling burning is more serious. Another explanation involves the problem of water potential, where the water potential of plants flows from high to low water potential. When the salinity content in the external environment of the plant is high, the water potential of the external environment will be low and the water potential of the plant will be high.

At this time, the water inside the plant flows to the outside until it reaches equilibrium. Eventually, there is a lack of water inside the plant, and the phenomenon of burning seedlings occurs.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me a lot, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you. That's all for sharing, if you like me, please follow me. If you guys have any ideas, you can let us know in the comments below.

It may be caused by a drought problem. The important thing is to pay attention to irrigation, first flood irrigation to improve moisture, timely sowing, and wait for wheat seedlings to emerge and seedlings to be watered immediately to supplement the water required for wheat growth.

It may be because of too much water, which cannot be absorbed, and the sun's irradiation, which causes the cells to lose water; It is advisable to consult with relevant experienced people to see if there is a remedy.

This is mainly due to the reason of fertilizer, which is prone to this situation if the fertilizer is not used correctly, and it is generally necessary to irrigate more water immediately in this case.

In the process of planting crops, watering should also choose the right time to disturb the ants, if the temperature is too high to water immediately, this kind of messy lead situation will occur. Try to choose watering in the morning or in the evening.

The reason why crops will burn seedlings and reduce yield after irrigation is mainly because of the wrong way of fertilization, so we should pay attention to the method of fertilization in the later stage.

It may be caused by the use of fertilizer, and the use of fertilizer should be reasonable so that problems can be avoided.
