Ginger, also known as white ginger and Sichuan ginger, is a perennial herb of Zingiberaceae. Ginger not only has high nutritional value, but also is a kind of food with homology of medicine and food, which has the effects of appetizing, resolving phlegm and relieving cough, clearing away heat and toxic materials, etc. , so it is deeply loved by consumers. Then do you know what the cultivation conditions and methods of ginger are?

Cultivation conditions of ginger

1. Temperature: Ginger is native to tropical areas of Southeast Asia and likes warm and humid climate. Its cold resistance and drought resistance are weak, and plants can only grow in frost-free period. The optimum temperature for growth is 25 ~ 28℃, and germination is slow when it is lower than 20℃.

2. Illumination: Ginger is resistant to shade but not to strong light, and the requirements for the length of sunshine are not strict. Therefore, a shade shed or intercropping crops should be set up for proper shade during cultivation to avoid strong sunlight.

3. Moisture: The root system of ginger is underdeveloped, and its drought resistance and waterlogging tolerance are poor. Therefore, the requirements for water are particularly particular. During the growing period, the soil is too dry or too wet, which is not conducive to the growth and expansion of ginger and is easy to cause diseases and rot.

4. Soil: Ginger likes fertile and loose loam or sandy loam. Poor growth in low-lying areas with heavy viscosity and high water content, and poor growth in poor soil with poor water retention. It needs potassium fertilizer the most, followed by nitrogen fertilizer and phosphorus fertilizer the least.

Planting method of ginger

1, intertillage weeding: generally, after the emergence of ginger, intertillage with water 1 ~ 2 times to weed in time. In the vigorous growth period, the plants are gradually sealed and the occurrence of weeds is reduced, so manual weeding can be used, and it is best not to use herbicides in the production of pollution-free ginger.

2. Timely watering: Ginger is neither drought-tolerant nor waterlogging-tolerant, and has strict requirements on water content. It is wise to keep the soil moist during the growing period. During the high temperature period in summer, water should be watered in time to cool down, and the accumulated water in the field should be removed in time in rainy days to reduce the occurrence of ginger blast.

3. Rational topdressing: When the height of ginger seedlings is 30 cm, apply 20 kg of urea per mu, or water the seedlings with clear manure. Before and after beginning of autumn, 50 kg of compound fertilizer and 25 kg of potassium sulfate were applied. When the underground rhizome expanded, 65,438+00 ~ 65,438+05 kg of urea and 65,438+05 ~ 20 kg of potassium sulfate were applied per mu.

4. Timely soil cultivation: The rhizome of ginger grows in the soil and needs darkness and humidity, so it needs cultivation. Generally, after beginning of autumn, weeding and fertilization are combined, and the soil is cultivated for 2 ~ 3 times, and the sowing ditch gradually becomes a ridge to prevent the roots from being exposed to the surface.

5. Shading and cooling: Ginger is a shade-loving plant, which is not resistant to high temperature and strong light. It should be shaded in summer to promote growth. There are many ways of shading, which can be shaded by scaffolding or intercropped with corn, a tall stalk crop.

6. Pest control: When ginger rots, pull out the diseased plants, dig out the soil with pathogenic bacteria, sprinkle lime in the diseased holes and fill them with clean sterile soil. Spraying 50% chlorothalonil every 7 ~ 10 days for 800 times 1 time to control ginger moth and ginger maggot with trichlorfon or phoxim.
