The causes and Preventive measures of the latest Citrus seedlings

Citrus is our most common fruit, every autumn and winter season is its listing season, this is the market everywhere its figure, although it delicious, but in the planting process will appear a variety of problems. Zombie seedling is one of them, is a phenomenon that occurs on seedlings, so what is the cause of citrus zombie fruit? How do we solve this? Let's take a look at it together with Xiaobian.

I. Causes of formation

1. Congenital deficiency of seedlings

Citrus seedlings are congenitally deficient, weak in growth and few in root system. When planting citrus, the planting area is large, and not all seedlings can grow into big trees after planting, so many plantations will encounter this situation more or less.

2. Low-lying

Fruit trees planted in low-lying plots and low groundwater levels are easy to cause root water accumulation and waterlogging, which is also easy to cause stiff seedlings.

3. Soil problems

Citrus has strong adaptability to soil, but if the soil is acidic or alkaline and the soil layer is shallow, it will also affect its root growth, resulting in stiff seedlings.

4. Low organic matter content

The organic matter content in the soil is too low, because the plant lacks organic nutrients during the growth process, and cannot provide nutrients to the fruit trees in time, so the phenomenon of stiff seedlings will occur.

II. Preventive measures

1. Select strong seedlings

Be sure to carefully select and select healthy citrus seedlings when purchasing. If you accidentally buy seedlings with weak resistance, it is suggested to concentrate the weak citrus seedlings together for cultivation. When they are cultivated into healthy seedlings, transplant them in the field.

2. Ridging cultivation

If planted in low-lying plots, ridge cultivation can be used to raise the groundwater level and ditch drainage to avoid waterlogging.

3. Soil improvement

For plots with acid or alkaline soil, soil improvement can be carried out, such as quicklime to improve acidic soil, while for areas with severely acid or alkaline soil, soil improvement is difficult, so it is suggested to move citrus to plots with suitable acid and alkali for planting.

4. Fertilization

For plots with low organic matter content, a large amount of organic fertilizer containing humic acid can be applied at this time, which can improve the content of organic matter in the soil and is conducive to the absorption of nutrients by citrus plants.

5. Pruning and root promotion

For so normal seedlings, and in the appropriate plot feeling, but still shows the slow growth of plants, then it is necessary to analyze the reasons in time, because the root system is not developed, the absorption of nutrients is effective, can not meet the normal growth of citrus. At this time, some branches and leaves of the plant can be pruned, and at the same time, fertilization at the roots can be combined to promote more roots and cultivate strong roots.

The above is an introduction to the causes and preventive measures of citrus stiff seedlings. I hope it can help you. If you want to know more about related knowledge, please pay attention to us.
