Symptoms and prevention methods of low temperature injury of loofah

Let me tell you about the cold damage of loofah:

The main symptoms of low temperature

The symptoms of cold damage are varied, mostly manifested as leaf shrinkage and varying degrees of yellowing. Symptoms begin at the edges of the leaves, and dead edges will form after the cold damage ends.

Causes of low temperature disease in loofah

The poor insulation performance of greenhouses and other seedling facilities means that effective temporary warming measures cannot be implemented in cold weather or cloudy days, resulting in lower temperatures in the air and seedbed (or seedling container), directly harming the leaves. In addition, lower soil temperatures can harm the roots of loofahs and reduce their absorption capacity.

Low temperature prevention and control methods for loofah

(1) Build a high-standard energy-saving solar greenhouse; take effective temporary heating measures during disastrous weather; use electric hotbeds or brewing hotbeds for seedling cultivation.

(2) After the low temperature, water and fertilize the plants, and spray foliar fertilizer to promote the plants to resume normal growth.
