Planting method of ginger
1. If the ginger has sprouted, cut off the sprouting place. If it hasn't germinated yet, put the ginger in the water and wait for the ginger to germinate, or buy the sprouted multi-bud ginger directly.
2. Fill the flowerpot with soil for 9 minutes, plant the sprouted ginger in the flowerpot one by one, and cover more than half of the ginger with soil. Then put soil into the flowerpot and fill the whole flowerpot.
3. Water the flowerpot and put it on the balcony. After waiting for 3 days, the tender little teeth will come out.
4. Look at the late weather. A glass of water a day in hot weather and a glass of water for 3 days in mild weather.
Scientific planting techniques of ginger
1, sowing date: The sowing date of ginger is generally from late April to early May, and it is harvested before frost. Because ginger is warm, not cold-resistant or frost-resistant, it must be planted in sunny and warm weather in a warm and frost-free season.
2. Optimize the planting of ginger: after harvesting, choose ginger blocks with rich fat, full buds, uniform head size, bright color, no pests, no rot, no damage and no freezing as ginger seeds for storage.
3. Disinfect and accelerate germination: soak ginger with 500 times solution of 50% carbendazim before sowing, and then dry in the sun for 2-3 days. When the surface of ginger is shiny, it can be stacked and covered with straw to keep warm and accelerate germination. When the ginger buds grow to 1cm, they can be planted.
4. Adequate base fertilizer: Ginger has a long growth period, so it is necessary to apply sufficient base fertilizer. When preparing soil, 3000 kg of decomposed organic fertilizer and 25 kg of potash fertilizer are used as base fertilizers, and when sowing, 25 kg of urea 15 kg and compound fertilizer are used as seed fertilizers.
5. Sowing date: The sowing date of ginger only depends on the location. Sow in a frightened state with good irrigation conditions and high temperature, and sow before and after Tomb-Sweeping Day or in Grain Rain with no irrigation conditions and low temperature.
6. Sowing density: Generally, the planting density of ginger is about 5,500 plants per mu, and the seed consumption per mu is 800 ~ 1 1,000 kg. The bigger the ginger, the earlier the seedling emergence, the stronger the seedling and the higher the yield, so the seed block should be as big as possible.
Growth 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.
Prevention and control of ginger diseases and insect pests
1, ginger explodes. This is a devastating disease. Comprehensive prevention measures should be taken, specifically, digging drainage ditches to prevent waterlogging, combined with chemical prevention. Chemical control can use 65,438+0,500-2,000 times of liquid medicine, such as Jiangbao powder and green bar to soak the roots. If a diseased plant is found, it should be pulled out in time and treated with the above liquid medicine. After the ginger is harvested, the soil here should be taken away for deep burial.
2. Pests. The main pests of ginger are ginger moth, beet armyworm, ginger thrips and so on. Observe the insect situation and do a good job of prevention and control before Dafa dies. Pesticides such as Kuaishaling and Imidacloprid can be sprayed and controlled every 7- 10 day/time.
