Planting and cultivation techniques of Ginger

Ginger is referred to as ginger, also known as turmeric, the ancient name ginger; originated in China and Southeast Asia and other tropical regions. Now it has been widely cultivated in subtropics and tropics of the world, mainly in Asia and Africa, and common in Europe. Followed by Jiangxi, Anhui, Sichuan, Hunan, Hubei, etc., with a total planting area of about 20,000 to 30,000 hectares. In the north, Shandong is the main producing area, in addition, Henan, Shaanxi and other places are also more cultivated.

The main results are as follows: 1. Ginger is fond of temperature and shade in the plot, and the soil layer is deep, flat, loose and breathable, fertile and convenient for drainage and irrigation.

2. Applying sufficient basic fertilizer and formula fertilizer before planting ginger, 667m2 applied high quality circle fertilizer 5000kg, furrow applied soybean cake 120kg, ternary compound fertilizer 50kg, potassium sulfate 50kg, boron fertilizer 1kg, zinc fertilizer 2kg. The effect of mixed application of boron and zinc fertilizer is better than that of single application.

3. Select ginger species and cultivate strong buds when drying ginger for the last time at the end of February and the beginning of March, choose healthy ginger pieces with fat, plump, bright skin, fresh meat, no shrinkage, no decay, no freezing, no diseases and insect pests as seeds, soak seeds with 100 times 40% formalin 10min, and promote germination in the adobe Kang. The pool is 60-70cm high, and the length and width depend on the number of ginger seeds. First spread the wheat mash dried by 10cm in and around the pool. The temperature was high before and then low (22 ℃ in the early stage, 25 ℃ in the middle stage, 20 ℃ in the later stage). The buds germinated in about 10-12 days, and then planted after about 10 days when the ginger buds grew to 0.5-1.5cm.

4. Plastic film mulching is suitable for early sowing. Generally, planting begins when the soil temperature is more than 15 ℃, and the implementation of plastic film mulching can be advanced to the first ten days of April. Watering in time when planting, spraying ginger and garlic grass to weed, 667m2 with 100g 45kg mixed with water, then mulching, and pressing a mound every 5m to prevent strong wind, the plastic film was removed at the beginning of July.

5. Planting density Ginger was cultivated with row spacing of 60-65cm and plant spacing of 20cm. 5500 plants were planted in 667m2.

6. Timely shading and soil cultivation ginger is a shade-tolerant crop, the seedling stage is in late spring and early summer, the weather is hot, the sun is strong, and the air is dry. It can grow well only in the condition of flower shade. That is, after planting, 70-80cm high straw or vertical perforated black sunshade omentum was inserted on the south or west side of Jianggou.

7. Rational fertilization, watering and light application of seedling fertilizer, heavy application of branch fertilizer and supplementary application of autumn fertilizer. The ginger seedlings grew to 30cm and had 2-3 branches when combined with watering, the first topdressing was carried out, and urea 25kg was applied to 667m2. In the middle and last ten days of July, complete fertilizer and quick-acting fertilizer with long-lasting effect should be applied, and ternary compound fertilizer 50kg and potassium sulfate 50kg should be applied to 667m2, watering once every 4-5 days.

8. In the later stage, the open field cultivation of ginger was harvested in late October, and the harvest time could be delayed by 20 days in the later stage, with ventilation, 20 ℃-25 ℃ in daytime, no less than 8 ℃ at night, and watering once 2-3 days before harvest to make the soil moist, beneficial to harvest and good color of ginger.

9. The main diseases of pest control are ginger blast, and the pests are ginger borer and beet leaf moth. The pests were sprayed with 2000 times of 25% Kuaishaling EC, the ginger blast should be rotated, the disease-free ginger species should be selected, the diseased plants should be removed, disinfected with lime and the diseased soil should be eliminated.
