When is the planting time of ginger?
Planting time of ginger
The sowing period of ginger is generally from late April to early May.
Before sowing, carefully select ginger seeds and remove moldy, rotten and withered ginger slices. Choose 50 for planting ginger? 1 00g Yes1? Two pieces of ginger with strong buds are better. Large Jiang Ye can be planted, but the amount of seeds is large and the cost is high. It can be cut with a knife or opened by hand, but the wound should be disinfected with plant ash or lime before sowing.
Before sowing, it is best to soak ginger seeds with chemicals to accelerate germination. Methods The planted ginger was spread out and dried. Two days later, soak the seeds in 1:l: 120 bordeaux solution for 10 minute, then take out the ginger, layer by layer with wet sand, and cover it with a film with a thickness of about 30? 40 cm, keep the temperature at 20? 30℃,8? /kloc-can germinate in 0/0 day, and sow according to the size and strength of the bud. 300 grains per mu? 500 kilograms.
Planting conditions of ginger
1, Temperature: Ginger is native to tropical China and East Indies, and likes to be warm, so the growth of rhizome (ginger block) needs higher temperature. It can germinate above 16 ~ 18℃, and ginger grows rapidly at 20 ~ 27℃, with an average monthly temperature of 24 ~ 29℃, which is most suitable for rhizome meristem growth. When the temperature is lower than 15℃, the growth will stop, and when it reaches 40℃, the germination will not be hindered. But below 10℃, ginger is easy to rot.
2, light: ginger is resistant to shade but not to strong sunshine, and the requirements for the length of sunshine are not strict. Therefore, when planting, we should build a shade shed or use intercropping crops for proper shade to avoid strong sunlight.
3. Moisture: The root system of ginger is underdeveloped, and its drought resistance and waterlogging tolerance are poor, so the requirements for moisture are particularly particular. Too dry or too wet soil during the growing period is not conducive to the growth and expansion of ginger slices, and it is easy to cause diseases and rot.
4. Soil nutrition: Ginger likes fertile and loose loam or sandy loam, and it does not grow well in low-lying areas with heavy viscosity and high water content, and does not grow well in poor land with poor water retention. Ginger needs potassium fertilizer the most, followed by nitrogen fertilizer and phosphorus fertilizer the least.
Planting techniques of ginger
Preparation before planting
1, fine soil preparation, base fertilizer. Select plots with fertile soil and good irrigation conditions, and carry out fine land preparation in early April. Combined with soil preparation, apply high-quality decomposed chicken manure or high-quality ring fertilizer 10000 kg as base fertilizer. High-fat water plot, according to 60? Sowing with 65 cm row spacing, using bean cake 100 kg, ternary compound fertilizer 50 kg, potassium sulfate 50 kg, zinc fertilizer 2 kg and boron fertilizer 1 kg as seed fertilizer.
2. Select ginger seeds and cultivate strong buds. About 30 days before sowing, take out the ginger seeds, remove the soil from the ginger slices, and choose healthy ginger slices with rich fat, full flesh, bright color, no shrinkage, no rot, no cold and no pests and diseases as seeds. It is required that the weight of ginger per plant should be more than 60 grams, and 500 kilograms of ginger should be used per mu.
3, dried ginger trapped ginger. Choose a sunny day in early March, at 8: 00 or 9: 00 noon, dry the selected ginger seeds on the sunny ground, and put them indoors at night, and cover them with straw curtains to promote the decomposition of ginger nutrients. Sun Jiang 3? 4 days, 10 days, keep the temperature at 13? 15℃ promoted nutrient decomposition and bud differentiation.
4, soaking seeds to accelerate germination. Picked and dried ginger is soaked in 200 times of pesticides such as Jiangwen powder, Jiangshengbao and Lvba for 10 minute, which can play a role in sterilization and disinfection. After soaking, the seeds are dried to accelerate germination. Put the ginger slices into a basket and germinate in the shed or in the sunny place, and keep the air humidity at 75? 85%, temperature 25℃, 20 days later, when the ginger buds grow to 0.5 cm, sow them in batches according to the size of the ginger buds.
Sowing and seedling management
1, plastic film mulching, early sowing. Sowing in April 15. Before film mulching, use 150g special herbicide per mu to spray water to remove weeds under the film. The film thickness can be 0.005? The width is 0.006 mm and 120 mm.
2, sparse planting, increase ginger slices. The suitable planting density of high-yield plots is 7000 plants/mu, the row spacing is 50-55 cm, and the plant spacing is 25 cm. The dosage of seeds is generally about 500 kilograms per mu.
3. Shade and promote growth. The emergence rate of ginger is over 50%, so the ginger field should be shaded in time to promote the healthy growth of Jiang Miao. The specific method is as follows: make the sunshade net into a banner and pull it between the ginger rows, and fix both ends with bamboo poles, with a width of 60? 65 cm, you can choose a shading net with a shading rate of 40%.
Fertilizer and water management in growing period
On the basis of careful soil preparation, proper basal fertilizer application, careful seed selection and scientific sowing, ginger must also be managed in the middle and late stages to obtain high yield. The main technical points are as follows:
1, lightly apply seedling fertilizer, and then apply branch fertilizer. Combined with watering in the first half of June, urea 25? 30 Jin promotes the growth of Jomally. In the first half of July, remove the plastic film, 50? Apply ternary compound fertilizer per mu. 60 kilograms. Before August 20, apply 35 kg of potassium sulfate per mu, and water it in time after topdressing. In mid-September, according to the growth of Jiang Miao, appropriate amount of potassium fertilizer or nitrogen fertilizer can be topdressing the aboveground parts, and potassium dihydrogen phosphate can be sprayed once every 7 days for 3? Four times.
2. Use water scientifically. Because ginger likes wet environment, there must be enough water in the ground. In order to ensure the smooth emergence of ginger, don't water ginger before sowing, wait until 70% of the ginger temple is unearthed. According to the weather, soil quality and soil moisture, we should master it flexibly. If the first watering is late, Jomally will be dry and the buds will dry up easily. Because plastic film has a good function of moisture conservation, it is not advisable to water too many times at seedling stage, and it is advisable to water a small amount under the film. It is best to water in the morning and evening in summer, not at noon. At the same time, pay attention to timely drainage after rain. Before and after beginning of autumn, ginger entered the vigorous growth period, and the water demand increased, which was generally 4? Water every five days to keep the soil moist. In order to ensure that ginger is not so sticky and easy to store after harvest, it can be watered for the last time five days before harvest. After applying branch fertilizer, according to the growth of ginger, soil should be cultivated twice in time. Three times, ensure that ginger is not exposed to the ground and promote the rapid growth of ginger pieces.
Prevention and control of ginger diseases and insect pests
1, ginger explodes. This is a devastating disease. Priority should be given to comprehensive prevention and control measures, specifically, digging drainage ditches to prevent waterlogging, combined with chemical prevention and control. Chemical control can be used in 1500? Soak the roots with 2000 times of liquid medicine. If the diseased plants are found, they should be pulled out in time, treated with the above liquid medicine, and some acupoints should be marked. After the ginger is harvested, the soil here should be taken away and buried deeply.
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 sumeruling and imidacloprid can be sprayed every 7? 10 day, 1 time.
