When do you plant ginger?
Ginger is usually planted in spring, and the best planting time in North China such as Shandong is from mid-March to mid-April, or before and after Qingming to Grain Rain. In the northern region, due to the low temperature in the Spring Festival, planting can not be done until the end of April to around May.
How to grow ginger?
1, seed selection
Choose healthy ginger, and eliminate diseased, rotten and deteriorated ginger. The size of ginger seeds is preferably about 50 to100g, and it is best to have two ginger buds. If you want ginger to germinate early, you can accelerate the germination properly. First, dry ginger for two days, and then soak it in Bordeaux solution 10 minute or so. Then, the ginger is stacked on the wet sand, covered with plastic film, and the temperature is kept at about 25 degrees, and it can germinate in about a week.
2. Planting
Ginger can be planted by drilling or hole sowing. When sowing, the ginger buds should be facing up, and the spacing between plants should be about 30, and the row spacing should be about 40 cm. After sowing, cover with soil, preferably with a layer of straw, to keep warm.
3. Moisture
Ginger likes humid environment, but it is afraid of both drought and waterlogging, so it is necessary to master the water management skills in ginger planting areas. Generally speaking, it is enough to keep the field moist all the time during the growth period of ginger, and the water content of the soil is kept at about 70-80%. Only when the soil is dry at the seedling stage can you water it, and you should water it with a small amount of water. In the vigorous growth period of ginger, you should generally water it 1 time for about one week. In addition, during the high temperature growth period in summer, you should pay attention to prevent water accumulation and waterlogging in the field after rain.
4. Topdressing
Ginger generally needs topdressing for about 3-4 times during the whole growth period, and the first topdressing should be carried out after the seedlings are in full bloom. At seedling stage, topdressing should be mainly based on light fertilization and light fertilization, and the types of fertilization should be mainly nitrogen fertilizer, and weak urea water or decomposed human excrement can be used to promote seedlings. The second topdressing is usually carried out in the vigorous growth period of newborn ginger in early June and July. At this time, it is recommended to apply 20-25 kg of NPK ternary compound fertilizer +8- 10 kg of urea per mu for topdressing. The third topdressing is usually carried out during the rapid expansion period of ginger pieces from early September to1early October, and about 25- kg of NPK compound fertilizer+10-15 kg of potassium sulfate or potassium chloride can be applied per mu.
5, pest control
Ginger diseases and insect pests focus on the prevention of ginger blast, and often go to the fields to inspect whether there are diseased plants. If diseased plants are found, they should be pulled out and destroyed immediately, and then the diseased points and the surrounding areas of the diseased plants should be watered with quicklime water, and other healthy Jiang Miao should be sprayed with drugs to protect them from the spread of diseases in the fields.
The above is the introduction of the planting time and technology of ginger. Ginger is a common crop, which is simple and easy to take care of. However, in order to effectively ensure the high yield and high quality of ginger planting, it is very important to do the above management points well.
