The market demand for salvia is large, is salvia a good variety?

Salvia is a deep-rooted crop that absorbs water and nutrients from the ground, so the requirements for water and fertilizer in planting management are not strict. As long as the soil is moist, it does not need to be watered in a normal year. As long as fertile farmland is chosen, the base fertilizer should be used for land preparation, and the first planted plot does not need ** fertilizer during the growth period.

Salvia miltiorrhiza is cultivated as a seedling, with nutrients stored in the root system, and there are multiple formed buds in the upper part of the root, so the buds are relatively neat after cultivation, and the seedling stage grows quickly, which can effectively inhibit the growth of weeds.

Geological topography: It is best to choose sandy soil plots with deep soil, loose soil, high terrain and good drainage. Flat land to make drainage ditches.

In the mountains and ridges, the lower slopes of the two places should be selected, and the slope should not be too large, and 10-30 degrees is better. The soil organic matter content should be greater than the value between and . Fertilization:

The single three roots are deep, about 33 cm or more buried in the soil. Therefore, after harvesting, the deep soil is more than 35 cm, combined with the land stop, and 2500-3000 kg of decaying manure or compost and 50 kg of superphosphate are put into each mu as soil and base fertilizer. Grind again before planting, rake the fine rake flat, make a high pit with a width of meters, and open deep drainage openings everywhere to help drain the water.

Selection of seedlings for cultivation: The survival rate of salvia seedlings is relatively high, and it is easy to reach the seedling field, Miao Wang, and Miao Village, with high yield and stability. Spring is planted in April-May, and autumn in late October.

You can't be late or late, you have to transplant early, take root early, and turn green early the next year. If you plant it, dig out 3323 cm of oysters according to the row spacing, the depth of the oysters depends on the length of the roots, add an appropriate amount of manure to the blood lipids to make basic fertilizer, and mix it evenly with the farmland, plant 1 2 seed propagation buds per hole, and the water depth is subject to the natural growth depth of the seed source, and it can be slightly exposed to late nights. If you plant it, you can sprinkle it with water.

Large-scale planting is also semi-mechanized work, which can be ditched, the saplings can be dispersed manually, and the soil can be covered with a machine for suppression.

Loose soil weeding in field management: Salvia miltiorrhiza grows slowly in the early stage, and should be weeded in time, generally before sealing the ridge, combined with autumn rain 1 2 times, after sealing the ridge, to remove weeds in time. Timely top dressing:

In mid-June, 50 kg of sulphur-free ammonium can be harvested. Open a shallow trench on the side of the plant and spray, then cover with soil. Prevention of pests and diseases:

The main pests and diseases of salvia are root rot and ground tiger. After the onset of root rot, the roots turn black and rot, the ground stems and leaves wilt and die, and this disease is prone to occur in the hot season of heavy rain in June and August. Harvest time:

Spring planting is from the late autumn of the year before the freeze, the autumn is the second year of planting in October and early November, the local stems and leaves can be picked after withering, when harvesting, pay attention to dig out the soil around the roots, and then go forward, dig out the roots, do not let the roots remain intact. Large-scale crops can be harvested by machine.

Salvia miltiorrhiza has a very wide role in China, is widely used in various industries, and has a very high market demand. In the past few years, the salvia market has been in short supply, because most people's work and rest time and diet are very irregular. Salvia miltiorrhizae, which is highly susceptible to neurasthenia and cardiovascular diseases, has a role to play in these diseases, and the market demand for salvia miltiorrhiza has increased.

Moreover, the planting cost of salvia is low, the market is high, and it has a very large profit margin. And the state still has a certain policy on the cultivation of medicinal materials, so the planting prospects of salvia are very good.

Salvia miltiorrhiza is a deep-rooted crop that can absorb water and nutrients from the ground, so the requirements for water and fertilizer are not strict in planting management; As long as the soil is moist, it does not need to be watered in a normal year; As long as the fertile farmland is selected and the base fertilizer is applied during land preparation, the first planting plot does not need to be top-fertilized during the growth period. Salvia miltiorrhiza is cultivated with seedlings, there is a root system to store nutrients, and there are already multiple buds formed in the upper part of the root system, so the germination is neater after cultivation, and the growth of seedlings is faster, which can effectively inhibit the growth of weeds, even if there are some fast-growing weeds, spray 1-2 times of salvia special herbicide, and there is basically no weed damage in the early growth stage (before June). When Salvia enters June, it has entered the vigorous growth period, and the lush branches and leaves basically cover the ground, so there is no room for the growth of weeds, as long as the management method is appropriate, the whole growth period of the year will not cause weed damage.

Therefore, the cultivation of salvia miltiorrhiza has not strict requirements for conditions, simple technology, extensive management, and saves trouble and labor, and can be planted on a large scale if there are conditions.

The cultivation of salvia is developing faster and faster, but the promotion of artificial planting technology is not satisfactory. If Danshen is planted on a large scale alone, its yield is unstable and the planting benefit is not obvious. In addition, due to the large use of pesticides and fertilizers in the planting areas, the soil structure has been seriously damaged, and some places have been seriously damaged by pests and diseases, resulting in a great impact on the quality of artificially planted salvia.

And the sales of salvia is also a big risk, so everyone must be prepared when planting to avoid planting failure.

It's not good to plant. Because salvia has high requirements for the growing environment and requires diligent management, salvia is not a very good species.

Salvia miltiorrhiza is a kind of precious Chinese herbal medicine, as a commonly used Chinese herbal medicine, in recent years, the salvia on the market is basically artificially planted, salvia is relatively simple, easy to manage, stable yield, low investment, fast effect in 1 year growth period, stable income.

Soak in water at about 30 degrees for 12 hours, then take it out and let it cool, add a small amount of edible alkali to rub, rinse it with water and then put it into a cloth bag for germination, put it in an environment of 25 degrees of temperature and 95 degrees of humidity to promote germination, pay attention to turning two or three times a day, and after a week or so, it is found that most of the seed germ is exposed and can be sown. If it is the Yellow River Basin, it is generally planted around August, and the North China is generally planted around April, when propagating by cuttings, it is generally appropriate to plant in April and May in the south, and it is appropriate to plant in June and July in the north.

Salvia can be planted in North China from mid to late March to early April in the solar calendar, and can be planted in the Yellow River Basin from June to August in the lunar calendar. Transplanting in the early spring of next year in 3-4 months, first get up and put it together on the top according to the specifications of the row spacing plant spacing depth of 35 cm 25 cm 6 cm, put the roots vertically into the hole, a hole section, the big head is upside down, do not turn upside down, water the soil about 2 cm, and the soil should not be too thick.

The most suitable planting time is from mid to late March to early April, and if it is planted in the Yellow River Basin, the most suitable planting time is around July to September. If cuttings are needed, they are generally carried out in June and July in the north and April and May in the south. In June and July in the north and April and May in the south, the branches of salvia miltiorrhiza with strong growth and disease-free were cut in unison, and cut into small segments 13 16 cm long, and the lower incision should be close to the stem node and be horseshoe-shaped.

Cut off the lower leaves, according to the row plant spacing 20 10 cm, the cuttings are obliquely inserted into the seedbed, the depth is 1 2 2 3 of the cuttings.

To ensure the effect, seedlings are generally raised first. Seedling rearing takes place at the end of June or early July, after the salvia seeds are harvested.

It is more suitable to plant in the spring, because there is more rain in the spring, which is suitable for the growth of this plant.

Generally, it should be planted in spring, because the temperature in spring is relatively high, and salvia is more convenient to plant, and it grows very quickly.

Planting around the Yellow River takes place around July, and the time varies from place to place, with most of the planting taking place in spring.

It is oval in shape and turns grayish-black when ripe. Salvia blooms from May to July every year, and the fruiting period is from June to August. Salvia miltiorrhiza prefers a warm, humid and sunny planting environment, and is more suitable for planting on sandy loam soil with thick soil, good drainage, medium fertility and good aeration.

At the end of March, temple sowing will be chosen. The width of the ditch is meters, the hole is drilled horizontally according to the row spacing of 33 cm, and the depth of the ditch is 1 cm. Since the seeds of salvia are small, they should be mixed with fine sand and sprinkled evenly into the furrows, and the beneficial soil should not be too thick.

After sowing, the seeds are not visible, they are covered with plastic film, and the temperature remains the same.

Soak the seeds in 30 35 warm water for 10 12 h. Then take it out and let it dry for a while. Add a very small amount of edible alkali and rub it.

Then rinse it with clean water and put it in a germination cloth bag or other container, put it in an environment with a temperature of 25 30 and a humidity of more than 95% to promote germination, turn it 2 3 times a day, and after 5 6 days, 40% and 60% of the seeds show radicles and can be sown. Height 30-80 cm.

The whole plant is densely covered with white and pubescence, the roots are slender, reddish, the stems are four-edged and erect, the odd pinnate compound leaves, opposite, the leaflets are usually 5, the apical leaflets are the largest, the petioles are also the longest, and the leaflets are ovate. racemes, apical or axillary, labial corolla, blue-purple.

Generally in mid-March, or early April, the temperature is particularly suitable for planting during this time, and the survival rate of salvia can be guaranteed.

It is best to plant in May. Because in this way, growth can be promoted in time, and it can also meet the conditions for growth and development and the required environment.

It is best to plant in late March or early April every year.

There is really no problem in the spring, and it will be better to plant before the Qingming Festival. If you can't plant before the Qingming Festival, then you can choose to transplant it in the summer, for example, in September and October. It is better to choose in spring and summer, not in winter, winter, in general, it stops growing, which is not conducive to the survival of plants, so it is really important to choose a suitable time, which cannot be ignored.

Although the market demand is large, it is still necessary to master certain essentials of planting. In the spring, we must choose some varieties well, good varieties can get a good harvest, when planting, if you can carry out natural propagation, and can leave some good seedlings is the best. Because only when the seedlings are good, the growth will be robust and there will be good income.

In fact, spring planting must do a good job of insect control and weeding. Wildfires can't be burned, and the spring breeze blows and grows, which is a very classic verse, and also describes that weeds can grow wildly. In the spring, the rhizomes will grow faster, and the weeds are the same, so be sure to deal with the weeds before planting.

If the weeds are not treated in time, then the nutrients will be absorbed by these weeds, which will naturally affect the crops we make.

Fertilization is also a more important spring, if you can't fertilize in time after sowing, it will affect the growth and development of this root system. <>

After hibernation, many animal pests and other pests will become active, so it is also necessary to do a good job of preventing pests and diseases during this period. Pests and diseases need to be sprayed with pesticides in advance, which can prevent some pests and diseases, and can also prevent many insects from entering the area where they are planted. After spraying pesticides, pesticide spraying prevention should be carried out every week or so, mainly to avoid some fish that have slipped through the net and continue to have scourges.

The Yellow River Basin: They know that the best time to plant salvia is from June to August of the lunar calendar, when the rain is relatively sufficient, the corn seedlings are also sealed to the ground, and fresh salvia seeds are sown in the corn fields.

Can be planted in the spring. First of all, it can meet the temperature requirements, and planting in the spring is also advantageous, and it can also promote the increase of yield.

Salvia can be planted in spring, the weather in spring is relatively warm, it is very suitable for planting, and it is also necessary to pay attention to watering and fertilization after planting.

Salvia miltiorrhiza is a typical perennial herb with a height of 35-80 cm. Its roots are elongated, cylindrical, thick and fleshy. Its appearance is brick-red, its stem is erect and square, it has 4 small nuts, and its shape is oval.

When the fruit is ripe, it turns grayish-black. Salvia blooms from May to July every year, and bears fruit from June to August. Salvia prefers a warm, moist, sunny growing environment, and is more suitable for growing in sandy loam soils with deep soil, good drainage, medium fertility, and good ventilation.

When planting salvia, it is generally necessary to choose an area with sufficient sunlight, deep soil and good drainage as the planting area, and try to choose sandy soil. If the soil viscosity is too high, it will affect drainage, which in turn will affect root respiration, causing root rot. After cultivation, the soil should be solid above and below, and it should be smooth and trouble-free.

Tall plots are faster and less time-saving, but the yield is not as good as that of ridge plots.

After transplanting, we must keep the soil moist enough to ensure the survival of the plants. Generally, it is not watered after survival, and it is timely furrowed or watered in time when it is dry. In the rainy season, water should be drained in time to prevent root rot, and watering should be done after top dressing.

Salvia miltiorrhiza continues to sprout and bloom from late April to May every year, in order to ensure that nutrients are concentrated in the root system to grow, in addition to leaving seeds, flower buds should be removed at any time. Select high-efficiency, low-toxicity, low-residue pesticides, strengthen pest and disease monitoring, optimize pesticide formulations, safely, accurately, alternately use pesticides, fully reduce the frequency and quantity of pesticides, and prohibit the use of pesticides during safety intervals. At the beginning of the disease, the leaves of the plant will produce small brown spots, the spots will expand to a gray-brown color, the leaves will be burned, and the plant will die.

Severe disease can affect salvia production.

When the soil is too sticky, with poor ventilation and moisture, it often causes root rot and wilts the whole plant, and the root system has strong germination ability and can reproduce by splitting the roots. The middle and upper segments of the root strip germinate and take root faster than the lower segment. When phosphorus is deficient, the leaves are green, sometimes reddish-brown, with obvious brown spots on the leaves in the early stage, enlarged spots in the later stage, dry and scorched, sometimes the leaves are twisted, and the heart leaves grow slowly.

In potassium deficiency, the leaves are green to dark green, the leaves are broad, the petioles are slender and weak, and they appear to be overgrown. There are sometimes large brown spots on the margins of the old leaves, the veins are dark green, and the other parts are pale green, and obvious spots can be seen. Salvia miltiorrhiza is the most to avoid stagnant water, and the ditch should be cleared and drained in time in the rainy season; When the weather is dry, ditch irrigation or watering should be carried out in time, and excess stagnant water should be removed in time to avoid water accumulation.
