Ginger prevents late growth
In the late growth period of ginger, the growth of stems and leaves on the ground slowed down, and the growth of underground ginger balls dominated. The nutrients produced by photosynthesis were mainly transported underground, making the ginger balls expand rapidly until they were harvested before frost. Ginger growth requires a certain temperature difference between day and night, the appropriate temperature during the day at 25 °C, 17 °C -18 °C at night, conducive to the production and accumulation of nutrients, reducing night respiratory consumption; water demand in the later period than the previous slightly reduced, requiring the soil to always maintain Wet, suitable soil relative humidity is 70% - 85%. Ginger requires a dark and moist environment during the expansion of ginger balls, so the thickness of soil should be suitable. Recently, there are many rainy days, the light illumination is insufficient, and the temperature is relatively low, which is unfavorable for the growth of ginger. In field management, premature aging should be prevented, growth period should be extended as far as possible, and loss should be reduced. Recent field management measures recommended: 1. To ensure a balanced supply of fertilizer and water. Recently, rainy days and more, Jiang Tian soil is too wet, should pay attention to timely drainage, cultivator and ridge soil, keep soil loose, conducive to ginger ball expansion. Nitrogen, phosphorus, and potassium fertilizers should be applied. If phosphorus and potassium are insufficient, it will not be conducive to the enlargement of ginger balls and will affect the yield. 2. Ginger is not frost resistant. Recently, due to the influence of cold air, the cooling rate is relatively large. It is necessary to listen to and watch the weather forecast at any time, and harvest it before it is revealed. The tender ginger should be harvested earlier. At this time, the ginger balls have high water content, less fiber, and less spicy taste, and are suitable for processing into other flavor foods. Ginger is generally harvested together with fresh ginger. Fresh ginger can be harvested after rain, or 2-3 days in advance to make the soil moist and loose. Ginger balls are not easy to damage when collecting ginger, which is conducive to storage. 3. During ginger storage, the suitable microclimate conditions for ginger cellars are as follows: the temperature is between 11°C and 13°C, the temperature is required to be almost constant, the relative humidity of the air is greater than 96%, and it is close to saturation but not too wet to ensure that the ginger block is not bad. Do not do it either. (Shandong Provincial Meteorological Center)
