Licorice seedlings are sown and raised, what is the appropriate temperature?

The temperature between 20 and 25 is the most suitable, and the vitality of licorice seeds is particularly strong, but the seeds should be treated in advance when raising seedlings.

Licorice seedlings are sown, and the temperature is generally around 60 is very suitable.

Generally, it is about 20 degrees, and licorice does not have a particularly high temperature requirement, and it is also very heat-resistant and cold-resistant.

Use two specific methods to plant sprout roots and seedlings cultivation method: first level the land, apply the fertilizer on the soles of the feet, plant and weed, take necessary management measures, make the seedlings grow rapidly, and after entering the autumn, if you need to plant the land, dig out the pre-planted licorice seedlings, and then put them in the ditch. Planted, tilted, upright seedlings had no effect on the emergence and growth of licorice. For the convenience of planting and later growth, it is better to lay them flat, with less hard work and easy to plant.

By digging edges, the saplings that grew in advance or the saplings that were dug up during excavation are dug up and buried in the ground to grow.

The growth after the store is no different from that of special planting, but the employment is far less than that of special cultivation, so licorice can continue to multiply and no longer be specially planted. Deep Morgan is an effective way to grow licorice in desert, reflective membrane areas, making licorice resistant to wind and drought. Moreover, it can improve the quality of medicinal materials.

However, the emergence time is late. The main factor affecting the germination rate is the size of the seedling roots, followed by the irrigation time after planting and the time when the seedling roots are exposed to the air. The root diameter of seedlings had the greatest effect on the emergence rate, and the emergence rate increased with the increase of seedling root diameter.

Epidermal treatment method of licorice seedsLicorice seeds are thick and hard, the seeds are not easy to germinate, and the epidermis is damaged, and the high-speed rolling of the rice mill is used to make the seeds rub against each other and damage the epidermis. Mix evenly and dry before sowing. Cultivation TechniqueLicorice is a leguminous plant.

The main types are licorice light and licorice bulking and licorice. Dried roots and rhizomes are medicines, and crude medicines are called licorice. It has the effect of strengthening the spleen and invigorating qi, relieving cough, dissolving phlegm, relieving fever and relieving pain, and coordinating medicinal properties.

Soil selection: Licorice is a perennial herbaceous plant of the legume family licorice, with developed cavity grinding roots, deep soil, direct drought and salt tolerance, strong amphotetrend, calcium fear, water immersion, and strong vitality.

Put the seeds in the ceramic pot, put each kilogram of seeds, put the seeds into the thick sulfuric acid of the attack, stir repeatedly with a smooth stick, and dry it for later use. Licorice sowing can be sown in the spring, summer, autumn, and third quarters. Germination is fast and there is a long growing period before winter.

After sowing, cover with soil rake sugar, continue picking, and the soil is covered after fertilization. Then appropriately reduce the number of times in Chongqing. Combined cultivation mainly exterminates weeds in the field, such as steamed seeds.

The main pests and diseases of licorice are rust, powdery mildew, red spider and so on. For rust, it can be prevented with a mixture of stone sulfur.

First of all, it is necessary to choose a piece of land with strong sunlight, and to learn some seeds of better varieties of socks, soak them in warm water overnight in advance, and then sow them after drying them. Generally, after sowing, irrigation water once a day, about a week or so can emerge seedlings, when the seedlings can be transplanted, guess Jian Ji to keep a certain distance, not too close, but also diligent weeding and insect control, but also diligent fertilization so that the licorice will grow particularly strong.

When sowing, you must select seeds, remove some bad seeds or seeds with poor performance, and then breed, you can soak them in hot water for a while, break the skin of the seeds, so that the seeds can grow better, and then plant the seeds in the fertile soil of the source state of simple and loose hail pants, and keep the drainage good, the salinity is low, and the temperature and humidity can be maintained, so that the seeds can germinate.

First of all, we must choose the right land for planting, and secondly, we must select seeds for treatment and sow seedlings in advance, so that we can better plant them quickly, and we must manage them in accordance with scientific methods. To remove weeds, and to top dressing on time, pay attention to the control of pests and diseases.

When to plant, mainly depends on the region, different regions have different climate and environment, we plant licorice and other Chinese herbal medicine plants, can not be very fixed to tell you which time period is the best planting, but to combine the climate and environment of the planting area to decide.

But it is not without rules to follow, spring comes late in the north, and the suitable time for planting is 3 May, and spring comes early in the south, so the planting time is also advanced, and Jiangsu, Shandong, Henan and other places can be sown in 2 April.

Some licorice planting information and planting techniques on the Internet are credible and not fully credible, and must be adapted to local conditions.

1.Licorice sowing method

Licorice can be sown in spring, summer and autumn, among which the best is sown in May in summer, when the temperature is higher, the seedlings emerge quickly, and there is a long growth period before winter. Before sowing, apply 4000 kg of high-quality farmhouse fertilizer per mu, 35 kg of diammonium phosphate per mu as base fertilizer, if sowing with seeds, the sowing method can be better by strip sowing or hole sowing, the sowing amount is 2 kg per mu, the row spacing is 30 40 cm, the plant spacing is 15 cm, the sowing depth is cm, 3 5 grains per hole, and the soil is covered after sowing and the rake is protected by the rake.

2.For soil selection

The cultivation of licorice should be below the groundwater level, good drainage conditions, soil thickness greater than 2 meters, no cemented layer, pH value of about 8, and the sandy soil with convenient irrigation is better. It is best to turn the ground in autumn, if it is too late to turn in autumn, spring turning can also be, but it is necessary to ensure soil moisture, break up the slump and level the ground, otherwise it will affect the whole seedling and strong seedlings.

3.Variety selection and seed treatment

Good seed is an intrinsic factor in the high yield of licorice. In our county, Ural licorice and glycyrrhiza glabra are generally selected as the dominant varieties. Those who use seeds as sowing materials, the seeds are milled with an electric rice mill before sowing, or the seeds are weighed and reset in the ceramic tank, and 30 ml of 80% concentrated sulfuric acid is mixed according to 1 kg of seeds, stirred repeatedly with smooth wooden sticks, and after 7 hours of stuffing seeds at a temperature of 20, then rinsed with water for many times and dried for later use, the germination rate can reach more than 90%.

4.Licorice growing environment

Licorice prefers dry climates with dark and humid conditions, long sunshine and low temperatures. Licorice grows mostly in arid and semi-arid desert steppes, desert edges, and loess hills. Roots and rhizomes are used for medicinal purposes. The most important thing to sow licorice is to look at the temperature, and the right planting conditions are the key.

Sowing time of licorice: It has been proven by many years of experiments that as long as the moisture conditions are suitable, when the temperature rises to 10, the treated seeds begin to germinate slowly, and germinate quickly and neatly when the temperature rises to 24-35. To ensure successful planting, no seeds are wasted.

Sowing can be done from early May to mid-August, but mid to late May is the best.

Sowing too early, the ground temperature and temperature can not meet the requirements of germination, the seeds can not germinate, and even rot still need to be replanted, although the seedlings are sown too late, because the growth period is too short, it is difficult to overwinter, and the seedlings are too little in the next year, which leads to a decline in yield, and the economic benefits are not high. The suitable sowing period can be determined according to the actual local situation, and the average daily temperature reaches 15; When the ground temperature reaches 20, the seedlings will be sown and the emergence rate will be ideal.

Sowing method of licorice: In areas where there is no irrigation condition only by atmospheric precipitation, the leveled land is ploughed again in the autumn of the first year, and the seeds are sprinkled on the ground according to the amount of gram 2 in the rainy season of the second year, and can be raked or raked. In areas with irrigation conditions, small animal power seeders can be used, and the depth should be mastered at about 2 cm, and the thickness of the covering soil should not exceed 3 cm.

In order to increase soil fertility and allow licorice seedlings to grow quickly, basal fertilizer is applied before sowing and then sown. Diammonium phosphate 15 g m2 and urea 15 g m2 can be applied. The row spacing is not less than 30 cm, watering immediately after sowing, and the surface should be kept moist within 20 days, so as to facilitate the seeds to take root and germinate, grow into plants, and gradually reduce the number of watering times with the growth of plants.
