When planting ginger, how many centimeters of soil is best to spread on top of ginger seedlings? Wha

How much temperature is needed inside the greenhouse to cover the shade net.

Before breaking ginger seeds, break the ginger pieces that have been promoted into small seed blocks of 75-100 grams, and keep 1 fat young shoot on each seed block. Combined with the broken ginger seeds, the seed buds should be selected again, and the ginger pieces with blackened base or browned ginger sections should be removed. After the bottom water of the discharged ginger is infiltrated, the ginger seed can be discharged.

There are two types: flat and vertical. When sowing flat, place the seed blocks horizontally in the furrow so that the direction of the young shoots is consistent; When sown vertically, the seed buds are always sown upwards.

Ginger growing conditions.

1. Temperature: Ginger is native to China's tropics and East India, and it likes warmth, and rhizomes (ginger blocks) need a higher temperature to grow. It can germinate above 16 18 degrees Celsius, and at 20 27 degrees Celsius, ginger blocks develop rapidly, and the average monthly temperature is 24 29 degrees Celsius is the most suitable for rhizome meristem, and the growth stops below 15 degrees Celsius, and germination is still unhindered when it reaches 40 degrees Celsius.

But below 10 degrees Celsius, ginger cubes are prone to decay.

2. Light: Ginger is resistant to shade but not strong sunlight, and the requirements for the length of sunshine are not strict. Therefore, when cultivating, shade sheds should be built or appropriate shade should be used to avoid strong sunlight.

Ginger planting time.

3. Moisture: The root system of ginger is underdeveloped, and the drought and waterlogging resistance is poor, so the requirements for water are particularly particular. During the growth period, the soil is too dry or too wet, which is not conducive to the growth and expansion of ginger blocks, and is easy to cause disease and decay.

4. Soil nutrition: ginger likes fertile and loose loam or sandy loam soil, and grows poorly in low-lying land with heavy clay and humidity, and does not grow well in barren land with poor water retention. Ginger has the greatest need for potassium fertilizer, followed by nitrogen fertilizer and phosphorus fertilizer.

If you want to grow better, you need to put it in a more humid abandoned species.

Just fold off the sprouted part and bury it in the soil. The tip of the bud is left on the soil.

Ginger is native to tropical and rainy forest areas, requiring a humid and warm environment, the suitable temperature during the growth period is 22 28, it is not cold-tolerant, and the aboveground part dies in frost. The underground part also cannot tolerate low temperatures of 0. It is also not heat-resistant, such as too high temperature, direct sunlight, and stunted growth, so it should be shaded in summer on cultivation.

The requirements for soil moisture are strict, drought resistance is not strong, such as long-term drought will wilt the stems and leaves, ginger can not expand, but if there is too much rain, poor drainage in the field, it will cause growth and ginger rot.

Ginger's requirements for nitrogen, phosphorus and potassium fertilizers: potassium needs the most, followed by nitrogen, and phosphorus is the least. In addition to the base fertilizer, the required nutrients also need top dressing, the seedling stage is mainly topdressing nitrogen fertilizer, and the rapid expansion of ginger blocks should be supplemented with organic fertilizer or compound fertilizer containing nitrogen, phosphorus and potassium.

Ginger is bogey. It is cultivated in loam or clay loam soil with a lot of humus, and the yield is higher, but the spicy taste is light, and the tissue is more tender, which is suitable for harvesting young ginger for vegetables. If cultivated in sandy loam soil with less humus, the yield is lower, but the pungent flavor is stronger, which is suitable for planting ginger or making ginger powder.

Ginger is suitable for growing in low-temperature sandy soil, take the female ginger in April, and plant it, and in May it will grow seedlings like tender reeds, but the leaves have a pungent taste, and they are long in pairs, much like bamboo leaves, but slightly wider than bamboo leaves. Around the autumn equinox, new sprouts like arranged fingers will grow, and this is the best edible ginger. After the autumn equinox, the longer ones are a little worse, and after frost, they are old and not suitable for consumption.

Well-drained, loose soil, fertile, not too sun-drenched place.

Eat radish in winter and ginger in summer, without a doctor's prescription. This sentence has already told us that the time of planting and lifting is before the beginning of summer. Around April-May, the temperature is required to stabilize above 16 degrees Celsius. Ginger prefers to live in fertile sandy soil.

Here are seven proverbs about planting and lifting, which are summarized through the hands-on experience of the older generation. 1.Eat radish in winter and ginger in summer, and use beautiful ginger to plant ginger.

This is the basic requirement for planting ginger, which is large and high-quality, stout and bright-colored. This is from a biogenetic point of view. All plants must be woody of good quality in order to reproduce offspring.

Generally speaking, it is harmless and disease-free, and a single piece of high-quality ginger weighing 100 grams or 150 grams can be used as a seed player. Female ginger is strong enough to provide adequate nutrients for later growth. Plant ginger in the beginning of summer, and take the mother in the summer solstice.

This phrase speaks of seeding requirements. The best time to sow ginger is the beginning of summer, and it is generally best to wait until it grows to 5-6 true leaves. At this time, the mother ginger can no longer provide nutrients to the ginger, so the mother ginger can be taken out at this time.

It's not that the fertile soil doesn't carry ginger, and it's not that the heroes don't go out of the countryside. This is the soil requirement for ginger. Ginger prefers to grow in moist and fertile soil, high organic matter content, rich in nitrogen, phosphorus and potassium, which is conducive to improving the quality and yield of ginger.

The soil for planting ginger requires deep ploughing of more than 30 cm, application of foot fertilizer, intensive cultivation, sandy soil at the bottom, and good permeability is not easy to rot roots. Top dressing on demand in each growth cycle of ginger, frequent fertilization, and the principle of small amount. Ginger grows in the ground, and the soil should be dry.

Indicates that ginger prefers moist but not waterlogging tolerant plants. Soil drought can affect plant development, slow growth or stagnation. However, excessive water can easily rot the rising and falling roots or cause root rot or other insect pests.

Ginger is a very delicate plant. When sowing, it is necessary to water reasonably according to the moisture level of the soil. If the soil is dry, soak the roots of ginger in water before planting.

Before the rain, the stagnant water should be discharged in time to prevent the appearance of rotten roots and seedlings. <>

Deeply planted onion and shallow ginger, this sentence requires ginger to be shallow planting, and the root system is generally distributed in a cultivated layer of more than 30 cm. With these characteristics of ginger mastered, we can prescribe the right medicine and grow high-quality ginger. <>

The time for planting ginger is generally from March to April every year, when the climate is relatively humid and comfortable, and planting ginger can have a very good emergence rate. Generally, acidic soil or sandy soil is chosen for planting, and the pH of the soil should be kept at about the same level.

Ginger is generally planted in the spring of April to May. Ginger is suitable for planting in loose and fertile fields with thick soil layers and easy irrigation.

Generally, planting is carried out in late April or early May, and it is necessary to choose sandy soil and relatively fertile soil to plant, so as to ensure the yield of ginger.

Ginger is usually planted from late April to early May. Ginger likes warm and humid environmental conditions, is not tolerant to low temperature frost, begins to sprout above 16 degrees Celsius, seedlings grow at a temperature of 20 25 degrees Celsius, stems and leaves grow at a temperature of 25 28 degrees Celsius, and stops growing below 15 degrees Celsius, so the planting time of ginger is generally from late April to early May, and the low-heat valley area is suitable for early and mid-March.

When planting ginger, you can take strip sowing and hole sowing, and try to place the ginger buds facing up when sowing, generally keeping the plant spacing about 30 inside, and the row spacing is about 40 cm. After sowing, cover with soil, and it is good to cover it with a layer of straw to keep warm.

Preferably in April. It is necessary to choose loose and fertile soil, and pay attention to the drainage of the soil, so as to increase the yield of ginger.

Ginger is generally grown from late April to early May, and is suitable for surviving in warm, moist soils.

Ginger has strict requirements for soil, with deep, fertile, loose, well-drained sandy loam soil, and grows well in neutral or slightly acidic soil. The root system of ginger is not very developed, mainly distributed in the tillage layer of 20 cm, and deep ploughing of 20 to 40 cm is extremely beneficial for ginger to form rhizomes. 2000 kg of basal fertilizer, 40 50 kg of plant ash and superphosphate are applied every 667 m2 during land preparation.

When doing furrows, it should vary from place to place, such as in areas with abundant rainfall, the size is about 3 meters, about 30 cm wide furrows between furrows, and the depth of the furrows is 15 20 cm in the early stage of growth, and as the plants grow, the soil can be deepened to 30 40 cm, which will be more conducive to drainage in the rainy season. Ginger is not suitable for continuous cropping, the continuous cropping yield is low, the rhizome is thin, the surface of the epilepsy sores, and it is easy to develop root rot. Sichuan and Zhejiang production areas should plant ginger at least every 2 years, and Shandong production areas mostly adopt an 8-year rotation system.

Generally, corn, vegetables, wheat, peanuts, sweet potatoes and other crops are mostly selected as the previous crops.

It has a wide range of soil adaptability, whether it is on sandy, loam or clay, it can grow normally, but it is still better to cultivate soil with deep soil layer, loose soil, rich organic matter, good aeration and drainage. However, different soil qualities have a certain impact on the yield and quality of ginger. Sandy soils tend to have lower yields, but the rhizomes are smooth and beautiful, with less water content and more dry matter.

Ginger prefers slightly acidic soil, and soil pH has a significant effect on the growth of ginger. Zhang Shulan et al. (1986) showed that in the range of pH 5 and 7, the plants grew well, but when the pH was above or below 8 or 5, the plants were short, the leaves were yellow, the growth was not vigorous, and the rhizomes were underdeveloped.

Propagation with rhizomes (ginger), hole planting or strip planting. When harvesting ginger in autumn, choose thick and light yellow color. The rhizomes with shiny and no scars of diseases and insects are used for ginger, which are stored in the cellar or stacked indoors with fine sand for later use.

In the south from January to April, in the north in May, take out the ginger to keep warm and promote germination, and then cut the ginger into small pieces, each piece retains 1-2 strong buds. Hole planting according to the row of plant spacing 40cm 30cm open hole, 13-17cm deep, first water manure water in the hole, after infiltrating the soil, each hole flat put 1 piece of ginger, and finally covered with fine compost and soil.

Strip planting according to the row spacing of 40cm ditch, after the application of base fertilizer, according to the plant spacing of 27cm, the overlying soil and the ground level. Sichuan production area pays attention to the depth of sowing, sowing depth (digging about 30cm), and constantly cultivating soil into a ginger, for ginger**; Sowing shallowly (digging holes 5-10cm) to make medicinal ginger, which is dried ginger**.

Ginger is an underground tuber crop, ginger root is weak and shallowly distributed, within 30 cm of topsoil, it is afraid of drought and waterlogging, likes water, likes fertilizer, is afraid of heavy stubble, and has strict requirements for soil.

Therefore, it is necessary to choose loose, fertile, thick soil layer, convenient drainage and irrigation, rich humus sandy loam or light loamy plot, with neutral or slightly acidic loam is the best. The soil quality is related to the spicy taste of ginger, and the ginger block on the sandy soil has a strong spicy taste and strong aroma, but the yield is low, so it is suitable to be planted ginger or dried ginger; There is a lot of humus or clay ginger cubes with light spicy taste, soft tissue, and more moisture, which is suitable for harvesting fresh tender ginger as vegetables; If the soil is too sticky and too heavy, it will lead to poor growth of ginger, and it is easy to accumulate water and cause ginger rot. Heavy cropping plots are generally rotated for more than three years.

Precautions for cultivating ginger:

It is to fertilize the land and water the ridges. Before arable land, 5000 kg of circle manure and 1000 kg of rotting chicken manure should be applied per mu, and 30-50 kg of potassium sulfate can be added to the plot with poor soil fertility, 20-30 cm deep, leveling and raking fine, and sparse sowing of wide ridges. Single-arch plastic film mulching, ridge spacing 65-68 cm, seeding furrow 25 cm deep and 10 cm wide; Mulching and double-film mulching cultivation is planted with one ridge and two rows, with a belt distance of 115-120 cm, a width of 50 cm in the ridge in the film, a width of 55-60 cm in the ridge outside the film, a ridge height of 20 cm, and a sowing furrow width of 8-10 cm.

After ridge formation, water the bottom according to the moisture. Plots with less than 70% soil relative humidity are watered in the sowing furrow, and the amount of watering is not easy to be too large. The time of watering depends on the texture of the soil, 1-3 days in advance.
