Ginger high yield secrets, ginger high yield cultivation technology??

1. Strict selection of land.

Ginger is suitable for planting in loam or sandy loam soil with deep soil, fertile soil and more organic matter to prevent the occurrence of ginger blast.

Second, it is not suitable for continuous cropping.

Continuous cropping is prone to ginger blast, which is a bacterial soil-borne disease, and the disease is generally more serious during continuous cropping.

3. Disinfection and germination.

1) Choose fully mature, hypertrophied, disease-free, 1-2 strong buds of old ginger as a seed ginger, before sowing need to be disinfected and germinated, there are many ways to disinfection, you can use 1::200 Bordeaux liquid to soak seeds for 20 minutes, so as to kill the germs on the surface of the ginger.

2) After the ginger is sterilized, take it out and dry it for 2-3 days, and then stack it when the ginger is dry, and then cover it with straw or hemp bag for heat preservation and germination, during which the temperature should be kept between 20 -25, and the ginger buds can be sown when they grow to 1cm.

Fourth, sow seeds at the right time.

The sowing period of ginger in South China is from February to March, and the size of ginger should be 70-100 grams at the time of sowing.

Fifth, reasonable dense planting.

The density of ginger should be about 40cm in row spacing and 20-25cm in plant spacing.

Sixth, apply sufficient base fertilizer.

Ginger is more resistant to fertilizer, and the growth period is very long, in the planting to apply sufficient base fertilizer, per mu can be applied pig manure 3000-5000 kg, potassium fertilizer 20-30 kg as base fertilizer.

7. Scientific top dressing.

Top dressing should be a small amount of many times from light to thick, when the seedlings grow to 15cm, apply 1 fertilizer, grow to 30cm and then chase 1 fertilizer, the later stage can be applied every 20 days or so 1 top dressing, the seedling period is mainly applied nitrogen fertilizer, rhizome expansion period should be more potassium fertilizer.

8. Shading and cooling.

Ginger is a negative-tolerant plant, but it is not tolerant to strong light and high temperature, and scattered light is conducive to growth, and is suitable for intercropping with taro.

Extended information: Ginger blast, also known as rot disease or bacterial wilt, mainly harms the roots and ginger blocks, infected ginger pieces are water-stained at the beginning, yellow-brown, and the inside gradually softens and rots, and there is a backlog of dirty white juice and smelly smell.

Prevention and control methods: 1. The implementation of the rotation farming system of water and drought can effectively control the spread of ginger blast in ginger seedlings.

2. If conditions permit, straw or straw can be covered between the rows to prevent the occurrence of ginger blast.

3. Choose some varieties of ginger seedlings with strong disease resistance.

4. After the rain, the field should be drained in time to prevent the ginger from being flooded.

5. Dig up all the seedlings around half a meter around the diseased seedlings. The soil is sprinkled with lime and the burrows are buried with a clean sterile substance.

6. Timely spraying after the ginger blast is found.

First, select excellent varieties, second, choose loose soil, and apply sufficient base fertilizer. Reasonable dense planting and strengthen fertilizer and water management.

Third, it is best to intercrop with high straw crops for proper shading, so as to be conducive to high yield.

Fourth, strengthen the prevention and control of pests and diseases.

The above is the secret of high value.

Hello, the secret of ginger's high yield is to water more and fertilize more, so that the yield will be more, and the management will be good.

I think the secret of ginger's high yield is first to bury a certain amount of bottom fertilizer in the ground, and then to plant it in this sandy soil, such as your soil is too compact, red loam soil is not good, that is, ginger with a particularly large sand content can grow well, and the sun should be sufficient, and the temperature should be appropriate.

Ginger (zingiber officinale roscoe) is the fresh rhizome of a perennial herb (40 100 cm high) of the genus Zingiber in the Zingiber family. The varieties are: Yufeng ginger, Shandong Changyi noodle ginger, Qingzhou bamboo root ginger, Shannong No. 1 ginger, Qingzhou small yellow ginger.

Aliases include ginger root, spicy cloud, hook finger, indica, hot boy, fresh ginger, and honey burnt ginger. The rhizome of ginger (dried ginger), cork (ginger bark), and leaves (ginger leaves) can all be used in medicine.

Chinese name. Ginger.

Foreign name. ginger

Alias. Ginger peel, ginger, ginger root, spicy cloud.

Latin scientific name. zingiber officinale roscoe

Binomial nomenclature. rhizoma zingiberis recens

The average annual temperature in most counties in the main producing areas of Guangxi is 18-19, and the average temperature in July is 39. The average temperature in January is -4 for extreme low temperatures; The frost-free period is more than 330 days a year. The annual rainfall is 900-1300 mm, and the relative humidity of the air is about 80%.

Ginger is native to the forest edge of tropical evergreen rainforests, forming the habit of adapting to a slightly shaded environment, and can grow well in the environment of slightly budding buds in spring and summer. [3]

He likes warm and humid climates, is not cold-tolerant, afraid of humidity, and afraid of direct sunlight. Do not work continuously. It is advisable to choose sloping land and slightly shady plots for cultivation. It is advisable to go to the top layer of deep, loose, fertile and well-drained sandy soil to heavy soil.

Microscopic features. Trait identification, rhizomes are irregular blocks, slightly flattened, with finger-like branches, 4-18cm long, 1-3cm thick. The surface is yellowish-brown or grayish-brown, with links, and there are stem marks or buds at the tips of the branches.

It is brittle, easy to break, light yellow in section, obvious annular lines in the endothelium, and scattered vascular bundles. It is fragrant and has a peculiar and spicy taste.

The secret of high ginger yield is to boil it in brown sugar ginger water and drink it.

You need a suitable planting environment, a suitable air temperature, and a suitable climate for brushing, which is a great secret to ginger.

Ginger is highly productive and secretive, and there are too many medicines.

1. Land selection, land preparation, and sowing: choose plots with loose, fertile and well-drained soil. Soil preparation and fertilization, selection of excellent varieties, cut into small pieces of planting, planting and applying foot fertilizer, watering thoroughly, after planting underground, and then spraying the new high lipid film soil surface, can protect moisture and waterproof evaporation, sun protection and drought resistance, heat preservation and anti-freezing, soil layer compaction, suffocation and isolation of pests and diseases, improve germination rate.

2. Fertilization, watering, and weeding: ginger requires a large amount of fertilizer, and should be topdressed in time. In order to promote the elongation of young ginger rhizomes and improve the quality, soil cultivation is combined with watering, and it can be kept moist, cultivated and weeded (mainly by manual weeding), spraying new high-fat film greatly fertilizing the active ingredient utilization rate, not afraid of sun exposure and evaporation, can adjust the absorption of fertilizer and water, and prevent drought and rain.

3. Growth period: ginger should achieve high yield and good quality, spray the fruit on the foliar surface to make the underground fruit nutrient transport duct thicker, improve the vitality of the fruit expansion, smooth fruit surface, strong fruit shape, achieve high yield and improve quality.

4. Prevention of diseases and insect pests: insect pests have corn borer, the disease is mainly ginger rot disease, that is, ginger blast, mainly for the damage of leaves and rhizomes, with the most serious disease in the high temperature period, prevention and control methods: the implementation of crop rotation and stubble, the selection of disease-free ginger, the application of potassium fertilizer, maintain a reasonable moisture, timely spraying of targeted drugs before the onset of the disease to prevent and kill, and the application of new high-fat film to consolidate the killing effect.

Ginger is cultivated by traditional methods, with low yield and poor efficiency. If the new technology of "six changes" is adopted, the output of ginger can be doubled, and the specific operation technology is as follows:

1. Change the east-west line to the north-south. First dig the ground, level it, and open the north-south ditch. When the ginger seeds are placed, the original random discharge is changed to the east-west discharge, the ginger buds are concentrated in the center of the inner groove, the fan surface of ginger is stretched from east to west, and the main stem and leaves on the ground are distributed from east to west.

The main stem leaves of ginger can be shaded and shaded for the young shoots of ginger and grandginger that sprout later, which is not only conducive to promoting the normal growth of ginger, but also saves man-hours.

2. Change the single row of large ridges to double rows of flat ridges. Flat ridges are planted in double rows, with a small row spacing of 25 27 cm and a large row spacing of 51 53 cm. When sowing, open a deep furrow first; After sowing, the middle is furrowed and ridged to cover the soil, and the thickness of the soil layer should be reached, so that the ginger does not need to be soiled in the middle of growth.

3. Change the sparse planting to dense planting. Traditionally cultivated, ginger is cultivated at a density of 5,500 to 6,000 plants on 667 square meters. According to the characteristics of ginger shade tolerance, the density can be increased to 10,000 plants of 667 square meters, and the plant spacing is 14 16cm, laying the foundation for high yield.

4. Change the centralized fertilization to the deep ploughing. The traditional fertilization method is to concentrate the fertilizer in the sowing furrow, or place the pig and cow manure that has not been corrupted at high temperature on the ginger, which is easy to cause waste or damage to the sprouts. The new method is to sprinkle the organic fertilizer such as pig and cow manure that has been corrupted into the soil, turn the soil 20 25cm deep, rake the soil finely, then open a ditch and place the seeds, and finally apply a small amount of compound fertilizer.

5. Change the medium-term soil cultivation to no soil. The traditional practice is in the middle of ginger growth, through cultivating and hoeing, deep ditching between rows, and then breaking the ridge and cultivating the soil, so that the original sowing ditch becomes the back of the ridge, and the original ridge back forms a soil cultivation ditch, which often causes ginger to hurt the roots or die seedlings to reduce the yield. The new method of cultivation only needs to open a ditch between the large rows at the time of sowing or within 20 days after sowing, and cover the soil on both sides to ridge, which can avoid soil damage to the roots in the middle of growth.

6. Change the treatment to comprehensive prevention and control. The main pests and diseases of ginger are ginger blast, ginger leaf blight, ape leaf beetle, curved jumping beetle, stripe borer, etc. In the past, pests and diseases were found and then applied**, which was often difficult to ensure the efficacy, so it should be changed to comprehensive control based on prevention and control.

Artificial control. Before sowing, the residual leaves left in the soil are dried and burned, which can not only clean the field, but also reduce the number of insects and pathogens. Pharmaceutical prevention and control.

Ginger blast and ginger leaf blight can be controlled with Bordeaux liquid spray. If the condition is severe, it can be poured with 2000 times of 40% antibacterial agent. Use 5% phosphine EC 1000 times liquid spray to control ape leaf insects, curved jumping beetles and other pests.

Ginger is not strict on the soil, regardless of sandy soil, loam, clay can be planted ginger; It can be planted between the soils. Ginger: A cash crop that requires a lot of fertilizer, and the amount of fertilizer required varies from seedling stage, vigorous growth stage (germination stage) and mature stage (rhizome expansion stage).

At the seedling stage, the plants are small and grow slowly, and the amount of fertilizer required only accounts for about 10% of the total fertilizer demand.

During the vigorous growth period (germination stage), the amount of fertilizer required is the largest, accounting for about 80%. Ginger is a potassium-loving crop with a high demand for nitrogen and potassium, while a small demand for phosphorus, only one-tenth of that of nitrogen fertilizer. Therefore, the proportion of nitrogen, phosphorus and potassium uptake during the whole growth period is as follows.

In addition, ginger also has a certain demand for calcium and magnesium, which has a certain effect on the improvement of the yield and quality of ginger. For many trace elements such as silicon, boron, zinc, etc., the demand is less. The growth of ginger requires the application of nitrogen, phosphorus, potassium and other macro-element fertilizers in a reasonable proportion on the basis of sufficient organic fertilizer and microbial fertilizer, and the supplementation of calcium, magnesium, zinc, boron, silicon and other medium and trace elements.

Common symptoms of ginger deficiency and prevention measures.

1. Potassium deficiency: Symptoms: slow growth, short internodes, reduced leaf area, tightly arranged leaflets, forming a small angle with the petiole, rough leaf surface, wrinkled and curled downward.

The early leaves are dark green, later turn yellow, and then turn brown, the leaf color changes from the tip and edge of the leaf to the whole leaf, commonly known as "gold edge", the lower old leaves dry and fall off, and the inside of the tuber is blue.

Control measures: high potassium water-soluble fertilizer and foliar fertilizer and trim potassium dihydrogen phosphate spraying to ensure the ** potassium in the middle and late stages.

2. Calcium deficiency: symptoms: light green stripes appear on the edge of young leaves, and the leaves shrink; In severe cases, the terminal buds die, and the lateral buds grow outwards in clusters. It is easy to form a bunch of small tubers, and calcium deficiency can cause the tubers to split. Control measures: For calcium-deficient soils, foliar calcium sprays.

3. Zinc deficiency: Symptoms: The growth of zinc deficiency in ginger is inhibited, the internodes are short, the plant type is short, the top leaves are erect, the leaves are small, and there are gray to bronze irregular spots on the leaf surface, and the leaf margin is rolled.

In severe cases, brown spots or patches appear on the petioles and stems. Control measures: Foliar zinc can be sprayed during the plant growth period.

Ginger has a long growing season, requires a lot of fertilizer, and requires different nutrients at different times, so it can improve yield and quality by applying fertilizer formulations.

1. Sufficient basal fertilizer: ginger roots are weak and shallowly distributed, and heavy basal fertilizer is the key to high yield. Before land preparation, 2500 5000 kg of high-quality rotted chicken manure was sprinkled per mu, and ploughed after fertilization.

2. Suitable top dressing: Ginger should be fertilized reasonably according to the needs of the plant during the growth period. For the first time, lightly apply "strong seedling fertilizer".

The growth of plants at the seedling stage is small, but the growth period is long, usually in the seedling height of 25 30 cm, with 1 2 branches when the first top dressing, can be carried out with watering, spraying new high fat film on the surface of the plant, can prevent the infection of pathogens, improve the ability to resist natural disasters, improve the intensity of photosynthesis, and protect the seedlings to thrive.

3. Reapply "split fertilizer" (or "branch fertilizer", "turning fertilizer", etc.) for the second time. From late July to early August, around the beginning of autumn, ginger seedlings are in the period of "three strands", and the demand for fertilizer and water increases, so it should be combined with weeding in ginger field for top dressing, and spray Diling to make the underground fruit nutrient transport duct thicker, improve the expansion and vitality of the fruit, smooth fruit surface, and robust fruit shape.

4. Irrigation once every 10 days or so when the weather is dry, and watering should be done in the morning and evening in the high temperature season; Drain immediately after heavy rain to make the ditch unblocked. Ginger likes cool and moist, not resistant to high temperature and strong light, when the weather is hot, it is necessary to build a shed for shade, in the first half of August, the top of the ginger plant should be knocked off, every 7 8 days to hit 1 time, 2 3 times in a row; In late August, the ginger branches and leaves are already flourishing, and the ginger shed can be removed at this time. Water the last water 3 days before harvest so that the ginger can be harvested with moist soil, which is conducive to storage.

It is usually harvested in mid to late October, before the first frost arrives.
