What are the climate requirements for planting ginger?

Ginger is a perennial herb, and its origin is in the tropical region of Southeast Asia. Therefore, ginger likes to grow in a warm and humid climate. Tanjiao 1.8 ~ 2m deep, with a maximum diameter of about 2m. It is as big as an altar from top to bottom. Generally 1 m3 can store 250kg ~ 300kg of ginger slices. The size of wine cellar is mainly determined by geographical location and ginger storage. Ginger likes warm and humid climate, and can grow under the condition of average temperature 14-30 degrees. It can germinate above 65438 06℃, and the optimum temperature for promoting germination is 22-25℃. Sowing temperature must ensure that the ground temperature is stable above 15 degrees, and the most suitable temperature for plant stem and leaf growth after sowing is 25-28 degrees.

The yield of ginger per mu is about 2500 Jin, which is about 5 times that of local corn. As long as the price is the same as that of corn, the profit is five times that of planting corn, so plant it. When the temperature dropped to about 15℃, Jiang Miao stopped for a long time, and when there was a slight frost, Jiang Miao wilted, so we all harvested ginger before and after the first frost, or protected it with a shed, and then extended it for a while to increase the yield. Requirements of ginger on soil: Ginger does not have high requirements on soil texture, but loam with deep soil layer, loose soil, rich organic matter and good ventilation and drainage is the most suitable for ginger planting. Ginger likes neutral and slightly acidic soil, and the range of pH 5 ~ 7 is good.

During the peak growth period, the water demand should be increased, and the soil layer should be kept moist, with a water holding capacity of 75%. If the water holding capacity of the soil layer is lower than 20%, the growth will be poor, the cellulose will increase and the quality will become worse. The water requirement decreases gradually in the late growth stage, and if the soil moisture is too high, it will easily lead to root rot. ? The root system of Zingiber officinale is underdeveloped and its drought resistance is weak. It is necessary to wet the soil and prevent waterlogging, so as not to cause rot. Ginger needs a lot of light to store and accumulate more photosynthetic products, and the length of sunshine is not strict. Rhizomes can be formed under both long and short sunshine, but the yield of rhizomes is the highest under natural illumination.
