How to Handle Stunted Grape Seedlings? A Detailed Guide to the Latest Solutions
Grapes, as a very common fruit in our daily lives, are planted over a very large area. And although grape growing techniques are simple and yields are relatively high, many problems are often encountered when growing grapes, and stunted seedlings are one of them, and stunted seedlings can have a major impact on grape yields. So what causes stunted grape seedlings? And how should they be handled? Let's take a look together with the editor below!
1. Causes
There are many causes of stunted grape seedlings, and the first is improper fertilization. During the grape seedling stage, because the seedling root system is distributed relatively shallowly, the demand for fertilizer is relatively low. When fertilizing, if too much fertilizer is applied in furrows, or if too much chemical fertilizer or compound fertilizer is used, it can very easily burn the roots and cause stunted seedlings. In addition, when establishing a vineyard, if the vineyard is in a low-lying area prone to water accumulation, it will have a major impact on the respiration of the grape seedling roots, hinder the root system's absorption of fertilizer, and also lead to stunted seedlings.
In addition, when applying organic fertilizer, if it is not fully decomposed, it will cause a large number of pests and diseases at the roots. Too much nitrogen released in the soil inhibits root activity and triggers diseases such as root rot. Then, when fertilizing in continuous cropping land, compound fertilizer is generally the main choice. After applying compound fertilizer, if biological bacterial fertilizer or organic fertilizer is not supplemented, excessive toxins will accumulate in the soil, affecting root development. Finally, damage to grape seedlings by root-knot nematodes and a lack of trace elements can also very easily cause stunted grape seedlings.
2. Prevention and Control Methods
If we want to reduce the occurrence of stunted grape seedlings, the first thing we must do well is fertilization. For newly planted grape seedlings, be careful to apply compound fertilizer lightly and appropriately, then appropriately increase the application of biological bacterial fertilizer. When fertilizing, also be careful to keep a distance between the fertilizer and the grape root system, keeping it at least about 20 cm, to avoid fertilizer burning the roots. Then maintain good drainage and irrigation in the vineyard, so that during the rainy season or when too much water is applied, water can be drained promptly, preventing the roots from being submerged by too much water and affecting the normal growth of the grapes.
When using organic fertilizer or farmyard manure, it must be fully decomposed before it can be applied. When using hormone fertilizers, ensure there is a clear product label, and do not use substandard fertilizers. Then increase the content of organic matter and beneficial microorganisms in the soil, avoid pest and disease damage, and improve root vitality. After newly transplanting seedlings, if the recovery rate is slow, then an appropriate amount of humic acid water-soluble fertilizer can be drip-irrigated into the soil to promote root growth, improve the resistance of the grape plants, and thereby achieve the goal of reducing stunted seedlings.
The above is a brief introduction to how to handle stunted grape seedlings. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
