The causes of the disease are diverse:
1. Drizzle. Improper use of herbicides, including improper selection of herbicides, excessive use of herbicides, improper use of time and methods, can cause ginger leaf curling.
2. Weather. If the temperature is too high or too low, root development of ginger can be poor. In addition, high temperatures, droughts and other extreme weather will cause root damage and poor development of ginger seedlings. The temperature in the early part of this year was high. Since April, it was in a continuous cold and rainy weather, which caused the ground temperature to not be able to pick up. The emergence of ginger was delayed and the root development was poor.
3. Fat damage. Due to the high yield of ginger, the annual usage of organic fertilizer and compound fertilizer is also high. In addition, the use of single fertilization in the management process has resulted in eutrophication of the soil on the one hand and increased salinization of the soil on the other hand. , resulting in more and more serious physiological diseases of ginger, ginger growth was inhibited.
4. Cultivation management. The thickness of soil layer planted by ginger should be uniform, and the thin and thick soil layer can also cause poor root development, affect the absorption of nutrients and water, and cause curled leaves and no trees. In addition, high alkaline irrigation water and unhealthy ginger seeds can cause ginger curling.
Ginger leaf light affects staged growth, and severely affects annual production. Therefore, the promotion of rooting and rooting of ginger seedlings is the key. The actual application shows that using a single, traditional solution has little effect. The results of application and promotion for many years showed that 0.136% of erythropolis wettable powder 10g + Anrongle 10ml + 100ml of pure natural active organic silicon has significant root-enhancing and root-removing effects per mu. "Zha Xiaoxie" and alleviate the phenomenon of stiff yellow seedlings caused by fertilizer damage and phytotoxicity.
This 50m distance measuring meter is made of two parts: the laser distance outside unit and the sole part laser measure module.
