How to prevent radish from lodging and not standing upright?

1. Insufficient light.

Radish seedlings need an appropriate amount of light during the growth period, if the long-term light is insufficient, the growth environment is too shady, will cause the seedlings to grow, the stems are slender and thin, so as to lodging, so after the seedlings grow, it is necessary to ensure that there are 4-6 hours of sunlight every day.

2. Overwatering.

If you water too much in the radish seedling stage, the soil moisture is too large, which will cause the seedlings to grow too fast, causing the seedlings to lodging.

3. Influence of germs.

If before sowing radish, the plot has not been treated, the soil will remain overwintering germs, and when the surrounding environment is suitable, the germs will spread through seedbed irrigation, germium manure, agricultural machinery, etc., resulting in the seedling infection caused by lodging, just the initial stage of the disease, the base of the seedling stem is water-stained light brown, and then becomes a thin line.

4. Too much fertilization.

The vitality of radish seedlings is relatively fragile, when just planted, in addition to applying thin basal fertilizer in the soil, there is generally no need to top dressing in the later growth process, if it is frequently fertilized for seedlings, it will lead to high soil temperature, radish roots are burned, and thus lodging.

As the saying goes: "the first radish and the second cabbage", after entering the Futian, it is necessary to prepare to sow radish, but this time period is in the high temperature period, high incidence of pests and diseases, high temperature and drought, continuous rain, storms, hail, floods and other natural disasters will have an impact on radish sowing. Therefore, according to the specific situation, it is necessary to sow radishes in a high yield period as much as possible, and also ensure that the quality can achieve the expected effect, so as to sell at a good price.

1.After the ambush, the weather forecast is continuous rain, so rush to sow seeds immediately. Before the ambush, it is necessary to carefully prepare the land for planting radishes, ridge and apply foot fertilizer, etc., and sow seeds as soon as possible.

At the seedling stage, it is afraid that high temperature, drought and heavy rain will hit the ground, resulting in no seedlings, or choking and dead seedlings after the emergence of seedlings. If there is rain in the forecast, you can rush to sow seeds before the rain and strive to emerge in time after the rain. If it is a continuous hot weather, it is best to choose rainy weather for sowing according to the weather forecast.

2.Late-maturing varieties seize the time to sow seeds, and do everything possible to protect seedlings and sow in shade. Late-maturing varieties have great potential for yield increase, but they need sufficient time for vegetative growth, so sowing seeds should be sown as soon as possible after incubation.

3.Early maturing varieties can be sown later. In many areas, early-maturing varieties are actually sown in the second dog, and these varieties are suitable for dense planting and can also obtain high quality and high yields.

4.The sowing time is selected according to the cultivation purpose. Radishes are not all for pickled radish, pickled radish or sauerkraut, or for storage, and some are also for the market in advance.

In this case, it is possible to sow seeds as early as possible, and to choose early-maturing varieties, but it is still necessary to place the radish expansion period at 20-25 degrees Celsius to produce high-quality radish.

5.According to the local climate, the sowing date can be flexibly controlled in the field. Different regions and the same region have different altitudes, shady slopes and sunny slopes The sowing period is different, generally sowing alpine mountainous areas, northern high latitude areas, paddy fields and shady slopes first, and finally sowing low mountainous areas, low latitude areas, flat land, dry land and sunny slope land.

Of course, the sowing period is only one aspect, good plots, fine management, water and fertilizer conditions and pest management are all indispensable, especially seedling management, how to ensure the emergence rate, how to avoid seedling death, weak seedlings and pests and diseases, etc., are very important. When raising seedlings, shading measures should be taken at the same time to maintain soil moisture, early seedlings and seedlings should be set to prevent water accumulation in the field.

Hello, the following are the reasons for the lodging of carrots, 1. Insufficient light radish seedlings need an appropriate amount of light during the growth period, if the light is insufficient for a long time, the growth environment is too shady, which will cause the seedlings to grow, the stems are slender and thin, so as to lodging, so after the seedlings grow, it is necessary to ensure that there are 4-6 hours of sunlight every day. 2. Too much watering If you water too much in the radish seedling stage, the soil moisture is too large, which will cause the seedlings to grow too fast, causing the seedlings to lodging. 3. The influence of the fungus is that before the sowing of the radish, the plot has not been treated, the soil will remain overwintering bacteria, and when the surrounding environment is suitable, the fungus spreads through the seedbed irrigation, fungus manure, agricultural machinery, etc., which leads to the seedling infection caused by lodging, just at the beginning of the disease, the seedling stem base is water-stained light brown, and then becomes a fine line.

4. Excessive fertilization of radish seedlings vitality is more fragile, just planted, in addition to applying thin basal fertilizer in the soil, the later growth process generally does not need to be topdressed, if the seedlings are frequently fertilized, it will lead to high soil temperature, radish roots are burned, and thus lodging.
