Causes of Chinese Chive Lodging and Detailed Explanation of Prevention and Control Methods
Chinese chive is a vegetable with extremely high nutritional value and is fairly common in daily life, but lodging often occurs during the cultivation of Chinese chive. The leaves of lodged Chinese chive press together, and over time they rot, bringing considerable losses to growers. So what causes Chinese chive lodging? How should it be solved? Let's take a look.
1. Causes of lodging
Chinese chive lodging mostly occurs in summer and autumn, when the climate is hot and humid. When fertility is sufficient, the leaves grow rapidly, which makes the false stem slender and weak, or the leaves become heavy and plump, causing a top-heavy condition and resulting in lodging. It is also possible that the planting density is too high, so the Chinese chive grows tall and thin, making it very prone to lodging.
2. Rescue methods
If lodging occurs in spring, half or one third of the upper leaves of the Chinese chive can be cut off. This can reduce the weight of the upper part, and at the same time improve the light conditions of the plant, prompting its false stem to grow thick and strong and gradually return to normal. If it occurs in autumn, old leaves or part of the leaf tips can be removed, or a wooden stick can be used to turn the lodged Chinese chive over to the other side, so that sunlight can dry the roots and the lodged side can receive sufficient light. At the same time, strengthen ventilation, and after a few days, turn it back again and dry the other side. After repeating this several times, it can be rescued.
3. How to prevent lodging
When sowing, pay attention to the sowing density. After sowing and emergence, thin and fill in seedlings in time to ensure the density between seedlings. After the seedlings emerge, follow the principle of “promote early, control late” to control later growth and prevent the seedlings from growing excessively. For Chinese chive with old roots, excessive topdressing and watering are not suitable, so as to avoid excessive growth. After rain, drain water in time to prevent waterlogging and root rot. Before the rainy season arrives, appropriately harvest the vigorously growing leaves to prevent lodging and the rot it causes, but leaf harvesting should not be too heavy, so as not to affect the normal growth of Chinese chive. To avoid lodging, supports can be built in the field. This is the main measure to prevent Chinese chive lodging.
