How is ginger produced with high yield? Ginger is like warm and moist, but afraid of direct glare. If you want to grow ginger with high yield, you can't choose continuous cropping. It is best to choose the soil with loose soil and fertile soil. The detailed content of high-yield ginger is discussed below. explain.
First, ginger varieties
The main varieties are white ginger, purple ginger, green ginger, turmeric and so on.
Second, planting high yield methods
1. Strictly choose the land to avoid continuous cropping
Choosing loose soil and fertile sandy soil requires convenient drainage and drainage, and it is not easy to accumulate water. At the same time, it is not possible to choose continuous cropping fields. It can be used for three to four years of rotation with rice, cruciferous and legume crops.
2, select ginger, promote early hair
Choose ginger, plump, full-bodied, bright-colored, fresh meat, hard texture, broth with 1-2 strong buds for ginger, soaked in 50% carbendazim 500 times before planting, dried for two or three days, etc. When the surface of the ginger is bright, it is covered with straw to carry out heat preservation and germination. The temperature is controlled at 20-25 ° C. When the ginger bud grows to 1 cm, it can be sown.
3, timely sowing, reasonable close planting
Before and after the Qingming or Guyu Festival sowing, seeding was carried out at the time of sowing, the distance was 35~40cm, the distance between plants was 26~30cm, the depth of the ditch was 10-20cm, and 500kg per acre was planted. Use 15 kg of urea and 25 kg of compound fertilizer as seed fertilizer, put the fertilizer into the ditch and mix with the soil, and pour water in one hour after sowing to keep the soil moist.
4, emergence management
As soon as possible after the emergence of the seedlings, the stems and vines are placed on the shelves to allow them to grow along the shelf, and attention is paid to controlling the growth height of the stems, which is also beneficial to weeding and topdressing.
5, topping
When the main stem of the plant grows to 1.4-1.5 m, the main stem and side branches are topped to control the vegetative growth in time; when the bud is blooming, the flower buds are removed every 10 days, which can effectively reduce the nutrients. Consumption, promote the transfer of nutrients to underground rhizomes.
6, apply enough base fertilizer, scientific topdressing
a. Ginger fertilization adheres to the principle of applying enough base fertilizer and multiple topdressing. When the land is being prepared, 3000 kg of decomposed organic fertilizer and 25 kg of potassium fertilizer are applied as base fertilizer per mu.
b. When the seedling height is 30cm, when 1-2 branches are used, 20 kg of urea should be applied once per mu, and the manure can also be poured into the seedlings;
c. Before and after the beginning of autumn, 50 kg of compound fertilizer and 25 kg of potassium sulfate are applied per mu.
d. In the expansion of ginger rhizome, 10-15 kg of urea and 15-20 kg of potassium sulfate are applied per mu.
7, shading and cooling, promote growth
Scaffolding shades, and high-stalk crop corn intercropping to cool down and promote growth.
8, drought prevention and flood control, timely soil
It is advisable to keep the soil moist during the growing period. In the morning or evening of summer, watering and cooling should be done. In the rainy season, measures should be taken to reduce the occurrence of ginger mites. In order to prevent the roots from being exposed, it is necessary to cultivate the soil in time.
9. Pest control
The main diseases of ginger are: rot disease and spot disease; the main pests are ginger carp and ginger carp.
a, disease prevention measures
Rot disease: timely remove the diseased plant, remove the pathogenic bacteria; spray 50% chlorothalonil 800 times solution at the beginning of the spot disease, spray once every 7-10 days.
b, pest control measures
Foliar spray control with trichlorfon or phoxim.
10, harvest
The best harvesting period is from late November to mid-December, that is, underground rhizomes are excavated after the plants are completely withered in autumn and winter.
