What should I do if the small sweet potato rains a lot and the old leaves are yellow?

There is a lot of rain in the small sweet potato, and the old leaves are yellow, there is no way to do this, I can only hope that he will clear it as soon as possible, and by the way, dig more ditches on both sides of the ground to let the water flow away.

Small sweet potatoes have a lot of rain and old leaves are yellow, so you can dig some drainage ditches to drain them.

What should I do if the small incense counts the rain and the old leaves are yellow? It must be raining a lot, you can go to the local crop hospital, you can go to the local dealer hospital and ask what kind of medicine is good?

Small sweet potatoes have a lot of rain and the old leaves are yellow, you can spray him with some pesticides, which are best pesticides with more potassium fertilizer. You can buy the pesticide at the Crop Hospital.

On a sunny day, turn the seedlings more and dry them.

In fact, the on-the-job method you are talking about is not caused by a lack of water, but for his own lack of some nitrogen, phosphorus and potassium, that is to say, you can eat some land when planting, non-plant ash or long-term consumption is OK, and the use of some cockroach potassium to melt and use a sprayer for foliar spraying can also have a good effect, which can increase the growth of Hongshu, and it can also increase yield, the effect is good.

Ditching and draining the water to drain the two waters as soon as possible is equivalent to improving the terrain and avoiding long-term rainwater soaking.

This may be due to too much rain, soaked and rotten roots, apply some potassium fertilizer or plant ash to it.

Many of the leaves of the sweet potatoes turn yellow on rainy days, so you can give them a little fertilizer, potash or something else.

Small sweet potatoes have a lot of rain, and the old leaves are yellow, so it may be a lack of some nutrients, I think you can try some soap, it should be better to use some effects.

If the yellowing of sweet potato leaves is not very serious, you can cut off the yellow leaves one by one to maintain the permeability of the whole plant. If the yellowing is more serious, take maintenance measures in time. Watering regularly, each watering to keep the potting soil moist, receive more sunlight every day, and keep warm in a low temperature environment.

What to do with the yellowed leaves of sweet potatoes.

When the sweet potato leaves appear yellow, if the situation is not very serious, it is a normal growth phenomenon, and only some yellow leaves need to be cut off. If the yellowing is more severe, the cause will be found out and the yellow leaf phenomenon will be effectively solved.

1. The soil is moist.

When sweet potatoes are in drought for a long time, it will lead to leaf yellowing. Therefore, it is necessary to water regularly, and the amount of watering each time to keep the potting soil moist and moist, and there should be no stagnant water. In the rainy season, drainage measures should be taken in time.

2. Plenty of sunshine.

Sweet potato branches and leaves need a certain amount of sunlight to grow, and if the long-term light is insufficient or exposed to the sun, it will cause the leaves to turn yellow. Therefore, in the breeding, it is necessary to receive more sunlight every day, which is conducive to the production of photosynthesis and promotes the growth of branches and leaves.

3. Warm environment.

Sweet potato leaves grow better in warm environments because they are not cold tolerant, and if they are exposed to low temperatures for a long time, they will cause the leaves to turn yellow. Therefore, it is necessary to take measures to keep warm in a low temperature environment to avoid the occurrence of frost damage.

Lack of nitrogen fertilizer: Many plants will have yellowing when there is a lack of nitrogen fertilizer, which is manifested by the transformation of leaves from light green to light yellow and yellow; It is often a gradual yellowing from the bottom up. Usually apply it diligently to Bika water-soluble fertilizer.

Watering too little: Watering too little can also cause the leaves of sweet potatoes to turn yellow, which is known as dehydration yellow. The first manifestation of this is that the old leaves of the plant turn yellow, and the slowly new leaves will also turn yellow, and the edges of many leaves will turn from yellow to dry.

Sunlight burning: Intense direct sunlight can cause the leaves of plants to turn yellow or even dry up, and this yellowing of plants caused by strong light exposure is caused by burns. The first areas to show yellowing are the tips and edges of the leaves.

Soil alkaline: When the soil is compacted, it means that the soil has been alkalized, and the leaves at this time turn yellow to see the phenomenon that the old leaves and leaf veins turn green and yellow.

Sweet potato leaves are yellow, either lack of fertilizer, or lack of water, dry up some fertilizer, water, after a few days to keep the leaves not yellow, grow very good, green.

There are two reasons for the yellowing of sweet potato leaves, one is lack of water and fertilizer, and the other is that there are diseases and insects.

The yellowing of sweet potato leaves is a sign of lack of nutrients, indicating that the soil of the land is not nutritious, and you can artificially supplement nutrients to achieve this condition for his healthy growth.

For example, you can water some farm manure or chicken manure.

If there is adjustment, you can use some compound fertilizers that we can use in ordinary crops, which contain sufficient nitrogen, phosphorus and potassium, which can be supplemented by plants.

If you are planting sweet potatoes, then it may be caused by lack of fertilizer or lack of water, and another reason is that too much fertilizer is burned to death.

Water with some potassium monobasic phosphate 1:1000.

The yellow leaves of sweet potatoes may be due to insufficient nutrients, insufficient light, and photosynthesis cannot ensure the normal growth of chlorophyll. The nutrients of the mother root are depleted, the function of the primary root declines, and the secondary root does not. Absorption is restricted, nutrient bodies are underdeveloped, leaves are thin, follow-up light is insufficient, and photosynthetic products (organic nutrients) are severely insufficient.

Treatment: Cut off the excess decaying branches, keep a robust branch, and renew the hydroponic nutrient solution. Or transplant it into a pot with flower loam or garden soil.

Supplement with reasonable light time.

Sweet potato leaves turn yellow

There are 2 reasons, one is a watering problem, and the other is a DAO temperature problem.

Sweet potatoes are not back especially water-loving.

A: If you water too much, it will cause yellowing. If the potting soil is too dry, it will lead to a lack of water and early hail drying, and finally it will affect the subsequent germination and growth.

Sweet potatoes are a drought-tolerant crop, but too much water and too little water is not conducive to increasing yields. Sweet potatoes are afraid of flooding, especially after tubing, which has a great impact on yield.

Temperatures that are too low can also cause yellowing. If sweet potato potted plants want to grow well, they must also have a suitable temperature, and at a temperature of more than 20 degrees, sweet potatoes will grow better, so we must pay attention to heat preservation when maintaining them in winter.

Sweet potato leaves are made in an uproar, not yellowing, and can be solved in a few steps by simply messing or closing the brother, delicious and nutritious!

Applying some nitrogen-containing fertilizer will do.

Control measures for yellow leaves of sweet potato (sweet potato).

The phenomenon of yellow seedlings in sweet potato fields can be roughly divided into the following types.

1. Insect pests: (red spiders, thrips) caused by yellow seedlings, mainly related to the climate, after planting Zheng Ye cavity seedlings in spring to mid-July, the overall drought is serious, red spiders and thrips breed a large amount, and the leaves lose green and turn yellow by absorbing the juice of sweet potato leaves.

2. Diseases. The yellowing of leaves caused by SPVD virus disease is mainly distorted, deformed, collapsed and shrunken, and the yellowing caused by soil-borne diseases leads to a large area of yellow seedlings through the spread of B. tabaci and soil-borne diseases. Like black spot disease, it mainly shows that the heart leaves are greenish as a whole, some of the leaves are yellow, some are purple and red, and they do not grow trees, the base of the seedlings is black foot-shaped, and there are round or fusiform patches at the wound, and the base does not take root.

3. Improper use of herbicides and growth control agents.

4. The amount of fertilizer applied to sweet potato is small and nutrients are missing.

Prevention and control measures. 1. Select detoxified sweet potato seedlings.

2. Timely insect control, especially in the case of arid climate, close observation of insect pests such as red spiders, thrips, and whiteflies, and once found in the field and seedbed, spray to prevent the spread.

3. Reasonable crop rotation, timely replacement of land, and selection of disease-free fields for planting.

4. Reasonable fertilization, choose fertilizers that contain nitrogen, phosphorus and potassium in addition to fertilizers, and it is best to contain a variety of trace elements.

5. The use of herbicides, at present, there is no herbicide in the sweet potato field, and it is best to test the application in a large area during use. It is recommended to use the special safety herbicide after seedlings to control sharp-leaved weeds, and the broad-leaved grass is used to use grass ammonium phosphorus to pass the ditch.

6. Strictly follow the instructions for the use of the anti-wang agent.
