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. It is better to choose ginger with 50- 100g and 1-2 strong buds for planting ginger. 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 ginger, it is best to soak the seeds with chemicals to accelerate germination. Methods The planted ginger was aired for 65,438+0-2 days, and then soaked in Bordeaux solution of 65,438+0:1:65,438+020 for 65,438+00 minutes. Then, after the ginger is taken out, it is layered with wet sand layer by layer, covered with a film with a thickness of about 30-40 cm, and the temperature is kept at 20-00. The amount of seeds used per mu is 300-500 kg.
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.
1. Pre-preparation, usually seed selection and soil cultivation. There is a detail in choosing this piece, that is, everyone gives priority to choosing multiple seedlings under the conditions of fat ginger slices, complete appearance and clear division. Many people think that ginger has fewer buds and bigger seeds, so it is easy to feed. In fact, the vitality of Jomally is far less than that of Bud. In the field where soil is raised, many people just clean up the grass and pile up some fertilizer.
In fact, you'd better dry the pulled grass and bury it back in the soil, because the fertility provided by the decay of these grass is the most suitable for this kind of soil. Then arrange the soil in strips, and apply fertilizer about 5 cm below the soil. Sudden sandy soil is the best.
2. Planting and maintaining ginger is a kind of crop that likes warmth and rejects strong light. The soil must be fertile. When the weather is too cold, you can cover it with some straw. Generally, ginger slices are buried 3-4 cm deep, so don't touch fertilizer. The planting amount per mu is about 300 kg, and the plant spacing 15-20 cm. Keep the soil moist all the time, and then pay attention to observation after budding. If the growth is not normal, you need topdressing. In general, topdressing will start at the height of Jiangmiao 10 cm.
3, field management should pay attention to daily temperature control, when the direct sunlight is too strong, it is best to add shelter to the field. In the general production process, topdressing is needed for 4-6 times, depending on the local soil fertility. Secondly, we should pay attention to loosening the soil, generally once every three months in Somatsu, and the loosening distance is about 4 cm. You needn't worry too much about weeds. You just need to clean up some big weeds, especially those that crawl. Other grasses do not threaten the growth of ginger because of their shallow roots.
