Ginger planting technology

[Network] agricultural raw ginger hi warm and humid climate, not cold, wet afraid, afraid of direct sunlight. So, ginger should choose a slightly negative slope and land cultivation. It is advisable for the soil grown by ginger to be deep, loose, fertile and well drained on the soil to heavy soil.

Ginger needs a large amount of fertilizer. In addition to applying the base fertilizer, it should be topdressed in time. In the germination period of ginger, there is no need for top dressing, which can easily lead to burning. The ginger seedlings are 30 cm high, and when they are 1-2 branches, they can catch 1 time. The specific reference standard is: one mu of ammonium sulfate or diammonium phosphate 20 kg, or potassium sulfate type compound fertilizer 30 kg; in the vigorous growth period of ginger, chasing fat, acre of cake fertilizer 75 kg, compound fertilizer 50 kg, combined with topdressing After 1 time of soiling, the second and third times of soiling were carried out in combination with watering.

Ginger cultivation generally requires sandy loam. Planting ginger is labor intensive. Not suitable for people who have lost their labor.

[Ginger planting technology] characteristics of ginger

Ginger roots are underdeveloped and shallow, mainly distributed in the range of about 30 cm. The stem is a fleshy rhizome. The axillary buds can be divided into one, two, and three times. The secondary rhizomes are densely packed into blocks. The more the number of seedlings is, the larger the ginger is, and the higher the yield. The ground stem is a pseudo-stem of the sheath sheath, which is 70-100 cm high and stands upright without ginger branches. Leaves lanceolate. Leaf sheath, green, leaves alternate, arranged in two rows. Ginger can bloom in the tropics, flowers are yellow-green or red, and rarely produce, with rhizomes.

[Ginger planting technology] Environmental requirements for ginger planting

Ginger warm and humid environment conditions, not resistant to low temperature frost, germination begins above 16 °C, seedling growth temperature is 20~25 °C, stem and leaf growth temperature is 25~28 °C, and growth stops below 15 °C. The annual temperature of the village committees such as Mud, Zhuangke and Anaheim is basically above 15 °C. The Z low-calorie valley area is very suitable for the growth of ginger and the yield is relatively high.

Ginger is weak and weak, and under strong light, the leaves are easy to wither. The farmer has "Ginger drying the sword (new leaf) is equal to life." The requirements for the length of sunshine are not strict.

Ginger is fertile and loose, rich in organic matter, and slightly acidic soil for convenient irrigation and drainage. The water requirements are strict, neither drought-tolerant nor wet, and the stems and leaves are withered due to drought, poor growth, high temperature and high humidity, and poor drainage is easy to cause disease. For the requirements of the three elements, potassium Z is more, nitrogen is second, and phosphorus Z is less.

[Ginger planting technology] varieties and types of ginger

According to the skin color of ginger, it is divided into white ginger, purple ginger, green ginger (also known as water ginger), and turmeric. Medium growth, many branches, Longqing turmeric is a dense seedling type turmeric. Ginger roots are dense and dense, with a large number of ginger pieces, arranged in double or multi-layered, with dense round meat, ginger, Yuxi turmeric, and western domain fine ginger.

[Ginger planting technology] land selection

Ginger is not suitable for continuous cropping. It should be rotated for 3-4 years with rice , cruciferous and legume crops. Strictly choose the land to avoid continuous cropping: choose sandy loam soil, loam soil and clay loam with high soil fertility, deep soil layer, good gas permeability, rich organic matter, and strong water retention and fertility. It is required to have a slightly higher topography, convenient drainage and irrigation, and less water accumulation.

[Ginger planting technology] ginger selection

Selected ginger species, promote early hair: choose ginger plump plump, skin color bright, fresh meat, hard texture, with 1-2 strong buds, weight 50-75 grams, disease-free ginger for ginger. The ginger is immersed and disinfected with 50% carbendazim 500 times before sowing. After the ginger is disinfected, it should be dried for 2-3 days. When the surface of the ginger is bright, it can be stacked, covered with straw for heat preservation and germination, and kept moist. The temperature is controlled at 20~25°C, when the ginger bud grows to 1cm. Seeding is available.

[Ginger planting technology] timely sowing, reasonable close planting

Ginger requires good irrigation conditions, high temperature, and does not germination, sowing in convulsions; no irrigation conditions and low temperatures, and need to germination, sowing before and after Qingming or Guyu. Seeding is carried out, the row spacing is 35~40 cm, the plant spacing is 26~30 cm, the ditch depth is 10-20 cm, and the planting is about 500 kg per mu. Use 15 kg of urea and 25 kg of compound fertilizer as seed fertilizer, and put the fertilizer into the ditch and mix with the soil. Drain the bottom water about 1 hour before sowing to make the soil moist. Place the ginger in the ditch, keep the direction of the young shoots consistent, and gently press it into the mud, and cover the wet soil about 5 cm.

[Ginger planting technology] scientific top dressing

Apply enough base fertilizer, scientific topdressing: Ginger has a long growing period, and should adopt the principle of applying enough base fertilizer and multiple topdressing. When preparing the land, the acre uses 3,000 kg of decomposed organic fertilizer and 25 kg of potassium fertilizer as the base fertilizer. When the seedling height is about 30 cm and 1-2 branches, chasing 1 time fertilizer, applying 20 kg of urea per mu, can also be used to pour the seedlings with clear manure; before and after the autumn, 50 kg of compound fertilizer and 25 kg of potassium sulfate are applied. About 15 cm from the base of the plant, the ditch is applied and covered with soil; when the underground rhizome is inflated, 10-15 kg of urea and 15-20 kg of potassium sulfate are applied.

[Ginger planting technology] Sunlight and moisture requirements.

Shading and cooling, promote growth: Ginger is a plant that is overcast and not resistant to high temperatures and glare, so it should be shaded during summer to promote growth. There are many methods of shading, which can be used to cover the shade, and can also be intercropped with high-stalk corn . Drought prevention and flood control, timely soil cultivation: Ginger is not resistant to drought, and is not resistant to cockroaches. It is advisable to keep the soil moist during the growth period. During the high temperature period in summer, it should be timely watered and cooled. It is better to water the water early and late. The rainwater days should eliminate the water in the field in time to reduce the occurrence of ginger. In order to prevent the roots from being exposed to the ground, the epidermis becomes thicker and the quality is deteriorated. It is necessary to carry out the soil cultivation, and generally combines watering and fertilizing for 2 to 3 times of soil, and each soil is about 3 cm.

[Ginger planting technology] daily growth management

@1, scaffolding promotes the growth of stems. When the stem of turmeric is 30cm long after emergence, it should be framed as soon as possible. The bamboo and wooden sticks with a finger length of 1.5-1.8m in length are inserted into the outer edge of the ditch and the hole. Each of the four upper ends is tied into a bundle, forming an "x" shape, in order to facilitate weeding and topdressing. The height of the strapping is 1.2-1.4m from the ground. The stems are placed on the shelves, allowing them to grow along the shelf, and pay attention to controlling the stems. Growth height.

@2, go to the top to be timely. When the main stem vine grows to a certain height (1.4-1.5m) and reaches the top of the top or side branches up to 20-30cm, it is necessary to top the main stem and side branches in time to control the vegetative growth; The flower buds are removed in time, usually once every 10 days to reduce nutrient consumption and promote the transfer of nutrients to underground rhizomes.

@3, do a good job in the prevention and control of pests in the growth process of ginger. The main diseases are rot and spot disease. The rot disease usually starts in July, and the disease is in the peak period from August to September. It is found that the diseased plant is removed in time, the diseased soil is dug, the lime is applied in the diseased hole, and the soil is cleaned with clean sterile soil. In the early stage of the onset of spot disease, spray 50% chlorothalonil 800 times solution, spray once every 7 to 10 days. The main pests are ginger carp and ginger carp, which are controlled by foliar spray with trichlorfon or phoxim.

@4, the harvest of ginger should not be urgent. The turmeric harvesting generally excavates the underground rhizomes after the plants are completely withered in autumn and winter. The harvesting time is good from late November to mid-December. The rhizome breeding is generally carried out in 2-3 years, and the yield is high. If it is urgently needed, it can be cultivated in the same year.

@5, some things that need to be paid attention to during the ginger planting process. Before planting, you should select the ginger species, and remove the mildew, decay, and dry diseased ginger. Ginger should choose 50~100g of ginger with 1~2 strong buds. Too big ginger can also be sown but it needs a large amount and high cost. It can be cut with a knife or by hand, but the wound Disinfect with grass ash or lime and then re-broadcast. Before planting, Z is soaked with seeds and germinated. The method is to spread the ginger for 1~2 days and then soak it with Bordeaux mixture of 1:1:120 for 10 minutes. Then remove the ginger and then use the tidal sand to pile it up. The code is covered with a film, the thickness is about 30~40 cm, the temperature is kept at 20~30 °C, and the germination can be carried out in 8~10 days, and the seed is sized according to the size and strength of the bud. The amount of seed per acre is 300~500 kg.

Ginger planting techniques are basically summarized here, and it is necessary for growers to report to local plant protection stations to ensure that they do not suffer from planting techniques.
