How should licorice be grown to achieve high yield?
I. Seedling raising and transplanting 1. Seedling raising The seedling bed should be selected from plots of humus soil or sandy loam soil with deep, fertile and loose soil. Apply 2000 kg of farmyard manure, 25 kg of superphosphate and 10 kg of potassium sulfate per mu as base fertilizer, plow more than 40 cm deep, level and harrow fine, and make 110 cm

Key Field Management Techniques for Licorice Cultivation
1. Licorice begins to emerge about 15 days after planting. After the seedlings are established, apply 15 kg of urea per mu along with irrigation to promote seedling growth. From late May to early June, open furrows and apply 30 kg of diammonium phosphate per mu, then irrigate. During this period, fertilize and irrigate scientifically to ensure vigorous seedling growth

Detailed Guide to Licorice Seedling Cultivation: From Sowing to Seedling-Stage Management
1. The seedling bed should be chosen in a plot of deep, fertile, loose humus soil or sandy loam. Apply 2000 kg of farmyard manure, 25 kg of superphosphate, and 10 kg of potassium sulfate per mu as base fertilizer, plow deeper than 40 cm, level and harrow fine, and make flat beds 100 cm wide for later use.

What issues need attention when growing licorice?
1. Seed treatment. Before sowing, treat the seeds with water at 60-100°C for 30 seconds; then soak them in warm water for 1 day and night, and the germination rate can reach 50%. If treated with concentrated sulfuric acid, remove the seeds immediately once the seed coat turns black and rinse them in clean water, then soak them in warm water, and sow when the seeds swell; the germination rate can reach more than 90%.

Detailed Explanation of Licorice Propagation Methods and Cultivation Techniques
Licorice propagation has three methods: seed propagation, rhizome propagation and division propagation. 1. Site selection and land preparation: Sandy soil and loose red loam soil are suitable; apply 2500 kg of farmyard manure per 667 sq m, deep plow 40-50 cm in autumn, harrow fine and level, and make high ridges 40-50 cm wide with furrows 30-35 cm wide.

What are the disease prevention and control methods for licorice cultivation?
The main diseases of licorice are: rust, brown spot and powdery mildew. The prevention and control methods are as follows: 1. Rust: when infected, yellowish-brown scar-like lesions appear on the underside of the leaves; after the epidermis ruptures, brown powder is released, which is the uredinium of the pathogen; in August-September, dark brown telia

Detailed Guide to Licorice Planting Methods and Cultivation Experience
1. Site selection and land preparation. Usually choose sandy loam soil that is fertile, loose in texture, well-drained, and low in salinity and alkalinity. Usually when preparing the land, a tractor is used to plow the field, with deep plowing of about 20 cm. At the same time, apply 2000-2500 kg of barnyard manure per 667 sq m as base fertilizer, then level and harrow finely.

Technical Specification for Rice Seedling-Throwing Cultivation with Plastic Trays and Dry Raising
Variety selection According to different cropping rotations, variety characteristics and the safe full-heading stage, select high-quality, high-yield, stable-yield varieties with strong tillering ability and good stress resistance that are suitable for local planting, either balanced panicle-grain type or large-panicle type. In the riverside and southern Jiangsu areas, early-maturing late japonica rice varieties are mainly used, supplemented

Three key stages to grasp in rice film seedling raising
Based on many years of practical experience, I believe that three key stages should be noted in the technique of raising rice seedlings under film: the closed stage, the hardening stage and the film-removal stage. The first stage: the closed stage, that is, from sowing to the one-leaf-one-heart stage. During this period the film must be tightly closed to create

Why should rice seeds be sun-dried before sowing?
Sun-drying rice seeds before sowing can effectively improve the germination rate and germination vigor of the seeds. The main reasons are: 1. Sun-drying seeds can promote after-ripening of the seeds and increase enzyme activity. After rice seeds are harvested, although they are sun-dried, winnowed and cleaned before being stored, because maturity and dryness vary, the air humidity and temperature during storage will also change. If the seeds absorb moisture, respiration becomes vigorous, and nutrients inside the seeds are consumed heavily, which often leads to weakened germination ability and reduced germination vigor. Sun-drying the seeds can enhance the permeability of the seed coat, so that they absorb water evenly during soaking and enzyme activity is increased.
