Key Points of Ginger Cultivation Techniques and a Detailed Explanation of Field Management Methods
Ginger is a common seasoning in daily life, and it is grown throughout our country. Besides its role as a seasoning, it is also an effective medicine for treating illness, with effects such as stopping vomiting, dispelling wind-cold, and strengthening the spleen and stomach. Soaking the feet in it can eliminate athlete's foot. As market demand expands, its planting area is also gradually increasing, so how should ginger be grown? Let's take a look at these techniques.
1. Land selection and fertilization
Ginger is a crop that is extremely sensitive to continuous cropping, so reasonable crop rotation should be used when planting. Choose soil with deep, loose, fertile layers and rich organic matter for planting, and the field should be slightly higher in terrain and convenient for irrigation and drainage. It can be rotated with rice, cruciferous crops, and leguminous crops. When preparing the land, apply sufficient base fertilizer to ensure vigorous ginger growth and increase yield. Apply 2500-3000 kg of decomposed organic fertilizer or farmyard manure per mu together with 50 kg of compound fertilizer as base fertilizer, spread it evenly over the soil, and deep plow to mix it thoroughly with the soil.
2. Seed selection and sprouting
Select ginger pieces that are plump and full, good in appearance and color, fresh, firm in texture, disease-free, and with 1-2 strong sprouts as seed. The best weight of a ginger piece is 50-70 grams. Before sowing, disinfection and sprouting treatment should be carried out, as this can improve the germination rate and make the seedlings emerge uniformly. First soak them for disinfection in a 500-fold dilution of 50% carbendazim. After disinfection, place them under sunny weather to dry for 1-2 days. Once the surface becomes shiny, they can be piled up for sprouting. Pile them together and cover them with straw, keeping the temperature between 20-25 degrees, and pay attention to moisture. When the ginger sprouts are about 1 cm long, they can be sown.
3. Sowing
The best sowing time is around Qingming Festival. Use the drill sowing method when sowing, control the plant and row spacing at 40×30 cm, with a furrow depth of 10-20 cm, and generally use 400-500 kg of seed per mu. When sowing, apply an appropriate amount of fertilizer as seed fertilizer so that they sprout quickly, and apply the fertilizer evenly into the furrow and mix it uniformly with the soil. Water once before sowing to keep the soil moist, then place the ginger pieces flat in the furrow with the young sprouts facing upward, press them into the soil, and cover with a 5 cm layer of fine soil. After sowing, rake the soil level.
4. Scientific fertilization and watering
After applying seed fertilizer, no topdressing is needed during the germination period of ginger. When 1-2 branches have sprouted and the seedlings have grown to 20-30 cm, topdressing should be carried out in time; generally, 15-20 kg of ammonium sulfate is applied per mu. The second topdressing is during the tuber expansion period of ginger, when a large amount of nutrients is needed for growth and expansion. At this time, 75 kg of cake fertilizer and 50 kg of compound fertilizer should be applied per mu, which can be combined with earthing up. Watering should adhere to the principle of light and frequent irrigation, keeping soil moisture within 70%. In summer, when temperatures are high and soil moisture evaporates greatly, water in time to maintain moisture. The best watering time is in the morning or evening, avoiding the high-temperature period at noon. In rainy seasons, drainage and waterlogging prevention measures should be taken. In autumn, ginger grows rapidly and needs a large amount of water, so at this time it should generally be watered at least once a week, keeping the soil moisture content at 75%-80%.
