If it is serious, it will be replanted, and if it is not serious, it can be alleviated and improved with fertilizer, and it can be improved with hormone-free rooting agent and microbial agent, and the fungus agent can choose more strains, such as 2 billion, 6 active bacteria, such a fungus agent has high activity, especially the fungus agent with Trichoderma harzianum, the activity will be higher.
When the soil moisture of cabbage fertilization is insufficient, it is necessary to water and create moisture before the land preparation after the application of basal fertilizer, and the main sowing method of Chinese cabbage in autumn is live seeding, and the live broadcast is divided into two ways: strip sowing and hole sowing.
The sowing time of cabbage is generally in August 1-20, you can apply rotting organic fertilizer + microbial agent as base fertilizer, the fungus agent can choose more strains, such as 2 billion, 6 active bacteria, such a fungus agent has high activity, especially the addition of Trichoderma harzianum, the activity will be higher, such manure + 2 billion fungus agent as base fertilizer can be, such as Ribery Yanwo microbial bacteria can.
If the bottom moisture is insufficient, water it in time after sowing to ensure that the seedlings are strong. After thinning seedlings and setting seedlings, water 1 water each. Watering at the beginning of the rosette promotes the growth of the trees. During the balling period, watering should be carried out in combination with top dressing, and the amount of watering should be large and uniform. In the later stage, appropriate water control promotes the core wrapping.

If you find that the urea has burned the ragan, you should immediately flood the vegetable field with large water.
After flooding, urea dissolves in water, and as the water sinks to the ground, it can avoid urea being too concentrated locally, thus burning the roots.

On the one hand, after urea is applied to the soil, the soil should have enough water content (generally about 70%-80%), otherwise it will affect the hydrolysis rate of urea and affect the play of fertilizer efficiency. Therefore, if the soil is relatively dry, the soil should be properly irrigated after the application of urea to facilitate the exertion of fertilizer efficiency. Because the nitrogen in urea is easy to release and volatilize, it is advisable to use urea to ditch and cover the soil after application.
In addition, because urea only contains nitrogen (generally 46% pure nitrogen), it can be appropriately mixed with superphosphate, potassium chloride or potassium sulfate, or well-rotted livestock manure for application. As for the question of whether the roots will be burned after the application of urea. It can be said that any kind of fertilizer may have a negative effect on the root system of the crop, mainly depending on the amount of application.
Too much fertilizer is concentrated in the roots of crops, resulting in a lack of water in the root zone products of crops that come into contact with fertilizers, which will cause adverse effects on the root system of crops.

In particular, it is emphasized that solid particles must not be applied, and they should be poured after being turned into a solution, and the concentration must not be high, the concentration of one thousandth is enough, and then it will be burned to death. To add that for potted flowers, it is actually best not to fertilize.

Hello! Kiss. After inquiry, vegetable urea can be fertilized again a week after burning.
It is recommended that you sprinkle urea on the soil around the vegetables, and then pour an appropriate amount of water, and all the dissolved urea will penetrate into the soil without loss, which can achieve the ideal fertilizer effect. Do not pour too much, it is easy to burn the roots.

Whether urea water can burn leaves in leeks mainly depends on the concentration of urea water.
When the concentration of urea water is too large, urea water will destroy the leaves of leeks, resulting in the symptoms of foliar fertilization, when the concentration of urea water is low, the burning hand will not burn the leek leaves, and it can also play the role of foliar fertilization, so that the foliar surface is thick and green. Foliar sprays are usually used, and urea concentrations can be between.
When irrigating crops, the concentration of urea is generally between 2 8%, pay attention to different crop varieties, the degree of resistance to biuret is different, most crops have poor resistance, and woody plants have greater resistance. >>>More
