Detailed explanation of the causes of chive lodging and the control methods
Chives are a vegetable with extremely high nutritional value and are fairly common in daily life, but lodging often occurs during the cultivation of chives. The leaves of lodged chives press together, and over time they rot, bringing considerable losses to growers. So what are the causes of chive lodging? How should it be solved? Let's take a look.
1. Causes of lodging
Chive lodging mostly occurs in summer and autumn, when the climate is hot and humid. With sufficient fertility, the leaves grow rapidly, which makes the false stem slender and weak, or the leaves heavy, causing a top-heavy condition and resulting in lodging. It may also be caused by too high a planting density, so the chives grow tall and thin and are therefore very prone to lodging.
2. Rescue methods
If lodging occurs in spring, half or one third of the upper leaves of the chives can be cut off, which 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 chives over to the other side, so that the roots are exposed to sunlight and the lodged side receives sufficient light. At the same time, strengthen ventilation, and after a few days, turn them back again and dry the other side. After repeating this several times, they can be rescued.
3. How to prevent lodging
When sowing, pay attention to the sowing density. After the seeds germinate, thin and fill in the 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, so as to avoid excessive vegetative growth of the seedlings. For chives from old roots, excessive topdressing and watering are not suitable, so as to avoid excessive vegetative growth. After rain, drain water in time to prevent waterlogging and root rot. Before the rainy season arrives, the leaves that are growing vigorously should be regulated and harvested appropriately, so as to avoid rotting caused by lodging, but leaf harvesting should not be too heavy, so as not to affect the normal growth of the chives. To avoid lodging, supports can be set up in the field, and this is the main measure to prevent chive lodging.
