How to deal with the latest stiff grape seedlings

Grape as a very common fruit in our life, its planting area is very large. Although the planting technique of grape is simple, the yield is relatively high. However, when growing grapes, we often encounter a lot of problems, and rigid seedlings are one of them, which will have a great impact on the yield of grapes. So what is the cause of the stiff grape seedlings? How should we deal with it? Let's take a look at it with the editor.

1. Cause of occurrence

There are many reasons for stiff grape seedlings, first of all, it is caused by improper fertilization. In the grape seedling stage, because the root distribution of grape seedlings is shallow, so the demand for fertilizer is relatively low. When fertilizing, if too much fertilizer is applied in the ditch, or if the amount of chemical fertilizer and compound fertilizer is too much, then it is very easy to burn roots and cause stiff seedlings. In addition, when establishing a vineyard, if the vineyard is low-lying and easy to accumulate water, it will have a great impact on the respiration of the roots of grape seedlings, hinder the absorption of fertilizer by the roots, and lead to the phenomenon of stiff seedlings.

In addition, when applying organic fertilizer, if it is not fully mature, it will lead to a large number of diseases and insect pests in the roots. Excessive release of nitrogen in soil inhibits root activity and causes diseases such as root rot. Then when fertilizing in the continuous cropping land, it is generally based on compound fertilizer. After the application of compound fertilizer, if there is no supplement of biological fertilizer or organic fertilizer, it will lead to excessive accumulation of endotoxin in soil and affect the development of root system. Finally, grape seedlings are damaged by root-knot nematodes, and the lack of trace elements can easily cause the phenomenon of grape seedlings.

2. Prevention and control methods

If we want to reduce the phenomenon of stiff grape seedlings, then the first thing we need to do well is to fertilize. For the newly planted grape seedlings, we should pay attention to the appropriate thin application of compound fertilizer, and then the appropriate application of biological fertilizer. When fertilizing, we should also pay attention to keep the distance between the fertilizer and the grape root, at least 20 cm, to avoid fertilizer burning roots. Then maintain the good drainage and irrigation of the vineyard, so that it can be drained in time in the rainy season and too much watering, so as to prevent the roots from being flooded and affect the normal growth of grapes.

When using organic fertilizer and farm manure, it must be fully mature before it can be applied. In the use of hormone fertilizers, to ensure that there is a clear product identification, do not use unqualified fertilizers. Then the content of organic matter and beneficial microorganisms in the soil should be increased to avoid convex window disease and improve the vitality of the root. After transplanting new seedlings, if the speed of slow seedling is slow. Then drip irrigation of appropriate amount of humic acid water-soluble fertilizer into the soil, promote root growth, improve the resistance of grape plants, so as to achieve the purpose of reducing rigid seedlings.

The above is a brief introduction to how to deal with stiff grape seedlings. That's all for today's introduction. This article is for reference only. I hope it can help you all.
