How to cultivate ginger for high yield

Ginger refers to the rhizome of the genus Zingiber. Sexual temperature, its unique "gingerol" can stimulate gastrointestinal mucosa, make gastrointestinal congestion, enhance digestive ability, can effectively treat abdominal distension, abdominal pain, diarrhea, vomiting caused by eating too much cold food. After eating ginger, people will have a feeling of fever, because it can dilate blood vessels, speed up blood circulation and open pores on the body, which can not only take away the excess heat, but also bring out the germs and cold in the body. When the body eats something cold, gets caught in the rain or stays in an air-conditioned room for a long time, eating ginger can eliminate all kinds of discomfort caused by heavy cold in time.

Morphological characteristics of Ginger

Perennial perennial root herbs. The rhizome is fleshy, flattened, fragrant and spicy. Leaves row, thorium-shaped to striate-lanceolate, 15-30 cm long, ca. 2 cm wide, apex acuminate, base attenuate, smooth glabrous, leaf sheath clasping; sessile. Flower stems erect, alienated by imbricate scales; spikes ovate to elliptic, ca. 5 cm long and ca. 2.5 cm wide; bracts ovate, light green; flowers dense, ca. 2.5 cm long, apex acute; calyx shortly cylindric; Corolla 3-lobed, lobes lanceolate, yellow, lip shorter, oblong-Obovate, lavender, with yellow and white spots, lobules on each side of the lower three knives Stamens 1, protruding, ovary inferior; style filiform, lilac, stigma radiate. The capsule is oblong and swollen about 2.5 cm, flowering from June to August.

How can ginger be cultivated to achieve high yield?

L. Strictly select the site to avoid continuous cropping.

Select sandy loam, loam and clay loam with fertile soil, deep soil layer, good air permeability, rich organic matter and strong water and fertility conservation, which requires slightly higher topography, convenient drainage and irrigation, and is not easy to accumulate water. Ginger is not suitable for continuous cropping, but should be rotated for 3-4 years with rice, cruciferous and legume crops.

2. Select ginger varieties to promote early development

Choose ginger with fat and plump pieces, bright skin, fresh meat, hard texture, with two strong buds, weighing 50Mel 75g, disease-free old ginger as ginger. Soak the ginger with 50% carbendazim 500 times solution before sowing. After disinfecting the ginger, the ginger can be stacked when the surface of the ginger block shines for 3 days, covered with straw to keep it moist, and the temperature should be controlled at 20-25 ℃. When the ginger bud grows to 1 cm, it can be sown.

3. Sowing at the right time and reasonable close planting

Good irrigation conditions, high temperature, and no sprouting, sowing in the sting season; no irrigation conditions and low temperature, and the need for sprouting, sowing around the Qingming Festival or Grain Rain festival. Strip sowing is carried out with row spacing of 35 cm to 40 cm, plant spacing of 26 cm to 30 cm, furrow depth of 10 cm to 20 cm, and seed use of about 500 kg per mu. 15kg urea and 25kg compound fertilizer were used as seed fertilizer per mu, and the fertilizer was mixed with the soil in the ditch. Watering the bottom water about an hour before sowing to make the soil moist, put the ginger pieces horizontally in the ditch to keep the direction of the buds consistent, and gently press the hands into the mud to cover about 5 cm of fine soil.

4. Apply sufficient base fertilizer and topdressing scientifically

Ginger has a long growing period, and the principle of applying sufficient base fertilizer and topdressing for many times should be adopted. During soil preparation, 3000 kg of mature organic fertilizer and 25 kg of potash fertilizer are used as base fertilizer per mu. When the height of the seedling is about 30 cm and there are 2 branches in 1 Mu, topdressing fertilizer once and applying 20 kg urea per mu can also be irrigated with clear manure water; before and after the Beginning of Autumn, 50 kg compound fertilizer and 25 kg potassium sulfate are applied per mu, ditching and irrigation are made at about 15 cm from the base of the plant; when the underground rhizome is enlarged, 10 kg urea and 1520 kg potassium sulfate are applied per mu.

5. Shading and cooling to promote growth

Ginger is a shade-loving plant that is not tolerant to high temperature and strong light, so shading should be carried out during summer growth to promote growth. There are many ways to shade, such as setting up a shed to shade, or intercropping with tall stalk crop corn.

6. Prevent drought and waterlogging and cultivate soil in time

Ginger is not resistant to drought or waterlogging, and is strict with moisture. During the growing period, it is appropriate to keep the soil moist, and during the period of high temperature in summer, it is better to water in time, especially early and late. Rain Water should timely eliminate stagnant water in the field in order to reduce the occurrence of ginger plague. In order to prevent the rhizome from exposing the ground, the epidermis becomes thicker and the quality becomes worse, it is necessary to cultivate the soil, generally combined with watering and fertilization for 3 times, about 3 cm each time.

7. do a good job in the control of diseases and insect pests

The main diseases are rot and spot. The rot disease usually begins in July, and the peak period is from August to September. It is found that the diseased plants are pulled out in time, the diseased soil is dug up, lime is applied in the disease hole, and the soil is buried with clean aseptic soil. 50% chlorothalonil 800 times solution was sprayed at the initial stage of the onset of spot disease, once every 7 to 10 days. The main pests are ginger borer and ginger maggot, which are controlled by foliar spraying with trichlorfon or phoxim.
