Detailed Explanation of Licorice Planting Methods and Technical Requirements
1. Selection of planting site. Under different climate and soil conditions, the yield and quality of licorice vary considerably. Licorice has strong adaptability to temperature conditions, while moisture conditions play a decisive role in licorice yield. According to the author's research, in regions of China's temperate zone with 300-500mm of precipitation, the rainfall in normal years can basically meet the growth needs of licorice, and it can be cultivated on land without irrigation conditions; however, to obtain high-quality transplant seedlings, the seedling nursery should have irrigation conditions. In areas with annual precipitation below 200mm, to obtain high quality and high yield, when there is no sufficient groundwater directly available for licorice use (groundwater level 2-3m), both the seedling nursery and the transplant site must have irrigation conditions.

How to Choose and Prepare the Site for Licorice Cultivation? Detailed Technical Points
Licorice has a very strong rhizome sprouting ability, extending horizontally beneath the soil surface around the old plant; one licorice plant can produce dozens of new plants within a few years. Under artificial cultivation, 3 years after sowing, new plants can be seen growing 3-4 meters away from the mother plant. Its vertical rhizome can also develop roots. The depth of the root system varies with soil texture and the depth of the groundwater table, generally within the range of 1-2 meters, sometimes reaching more than 10 meters, using the deep root system to absorb groundwater and adapt to arid environmental conditions.

Detailed Explanation of Licorice Cultivation and Grassland Reseeding Techniques
Licorice (Glycyrrhiza) is a wild medicinal and forage plant. Based on its biological and ecological characteristics, adopting agricultural technical measures can break seed dormancy and increase the germination rate; meet the water and nutrient requirements of licorice growth and development, and increase its biomass yield. 1. Licorice cultivation techniques (1) Seed treatment. Use a rice mill to scratch the seed coat, taking care not to crush the seeds; milling twice gives the best results, and the germination rate can be increased from 30% to over 80%. (2) Site selection and pre-sowing land preparation. On sandy land, sand-covered land, and beach land types

Detailed Explanation of Key Licorice Cultivation and Management Techniques
Licorice, also known as sweet grass root, red licorice, and powder grass, is a leguminous plant, with its root and rhizome used as medicine. Licorice is a perennial herbaceous plant, 30-40 cm tall. The root is thick and sturdy, cylindrical, with a sweet taste, and the outer bark is brownish-red. The stem is upright, slightly woody at the lower part. The leaves are alternate, and the flowers are papilionaceous, light purplish-red. The seeds are flat and round. The flowering period is June-July, and the fruiting period is July-September. Licorice is sweet in flavor and neutral in nature, with effects of clearing heat and detoxifying, moistening the lungs and stopping cough, and harmonizing various medicines, and is regarded as the elder of all medicines. Except for waterlogged lowlands and land with a high groundwater table, which are not suitable for planting, other

What are the cultivation methods for licorice? Detailed explanation of the key planting techniques
There are mainly two. (1) Direct seeding, generally done in rows, with a row spacing of 30-50 cm, a furrow depth of 3-4 cm, and 2 cm of covering soil, with a seeding rate of 2-3 kg per mu. Because direct-seeded products develop many branched roots, with the roots thick at the top and thin at the bottom, most fail to meet the quality standard, and because digging them out is laborious and highly labor-intensive, in production generally only seed-production fields use this method. (2) Seedling raising and transplanting, which is mostly used in production because of its high yield, excellent quality, low labor intensity, and high economic benefit. Generally, raising one mu of seedlings requires seeds

Scientific control methods for the first-generation Asiatic rice borer (Chilo suppressalis) in rice
According to surveys conducted across Hubei Province, the overwintering mortality rate of the Asiatic rice borer this year was higher than last year, and the post-winter population base was lower than last year but still relatively high. In addition, suitable climate conditions and the expansion of high-quality rice varieties are both favorable to the occurrence and damage of rice stem borers, and the first-generation Asiatic rice borer will show a major outbreak trend in the rice-growing areas of our province, making the control situation still severe. In response to this severe situation, all localities should strengthen leadership, raise awareness, actively organize control efforts, and quickly launch a campaign to wrest grain from the pests to ensure the safety of grain production. 1. Recognize the situation clearly and strengthen organizational leadership. Last winter, our province suffered freezing ice and

Rice gene design breeding: scientists cultivate new varieties
The aroma of rice is richer, like fruit, with higher iron and zinc content, so there is no need to supplement other nutrients; all of this can be achieved through molecular design of rice genes. Recently, the author learned from the "Crop Molecular Design and Innovation" symposium that China is currently building a large bioinformatics infrastructure platform to ensure that high-quality genes are "hit every time." Zhu Yingguo, an academician of the Chinese Academy of Engineering, said that taking rice as an example, japonica rice with a soft and glutinous texture is more favored, and people also hope that rice aroma will be richer or have special aromas such as "fruity" notes. Moreover,

Four key passes must be secured in controlling rice sheath blight
In recent years, sheath blight has risen to become the most important disease of rice, and it has four major characteristics: First, it occurs over a wide area. Second, there are very few varieties resistant to sheath blight. Third, the degree of damage is increasingly serious, even causing the plants to break through the top and lodge. Fourth, it first develops on the lower part of the rice plants, making it easy to overlook and miss the favorable timing for control. In control strategy, strictly securing the four passes is the key. 1. The pass of salvaging sclerotia - sheath blight mainly overwinters in rice fields in the form of sclerotia, and overwintering sclerotia generally have 60%-70% able to germinate from winter and spring through to early rice transplanting. The vast majority of sclerotia are lighter than water and can float with the water for a long time. After the rice field is irrigated,

How is rice dry-raised? Keep these thirteen points in mind
The trayless seedling-throwing technique for dry-raised rice uses a rice-specific slow-release medicinal-fertilizer super-absorbent seed coating agent called "Dry-Raising Nanny" to coat rice seeds, carry out dry seedling raising, and after pulling the seedlings, directly throw them into the field. It is a light, simplified, and cost-saving rice cultivation technique. Its key cultivation points are as follows: 1. Select the correct model. For application in dry-raised seedling throwing, the seedling-throwing type of "Dry-Raising Nanny" should be chosen. 2. Determine the dosage. Each bag (350 grams) of "Dry-Raising Nanny" super-absorbent seed coating agent coats 1-1.5 kg of rice seed. 3.
