What are the key cultivation techniques for Super Upland Rice 1
1. Intensive and meticulous farming: The quality of plowing and land preparation directly affects the uniform emergence and complete stand of upland rice, as well as the strength of the soil's water-holding capacity. Therefore, a good environment must be created for the growth and development of the underground parts of upland rice. 1.1. Deep plowing: The suitable soil tillage depth for upland rice planting is 18-20 cm, but the plowing depth must also be determined according to soil fertility and thickness. 1.2. Land preparation: The requirements for meticulous land preparation are level soil, with four-side ditches and a middle ditch, capable of both drainage and irrigation. Generally, the ditch depth is 1

Super dryland rice White Pearl No. 1 is suitable for planting in the north
White Pearl No. 1 was introduced from Israel by the Mingfeng Agricultural Science Institute of Harbin City, Heilongjiang Province, and was developed through years of purification, hybridization and selection by the institute. After years of observation, summary and analysis over hundreds of days and nights at nearly a hundred trial sites in Northeast China, Northwest China and North China, each difficulty was overcome one by one, and a new high-yield dryland rice variety suitable for large-scale cultivation in the north was bred, and it is known as the super dryland rice of the north. When planted in Harbin City, Heilongjiang Province, this variety has a whole growth period of 110-125 days, is medium-short-stemmed, with a plant height of 90-95 cm, and does not lodge.

Detailed Explanation of Key Cultivation Techniques for Upland Rice in Spring in Both Northern and Southern Regions
I. Early-Stage Management Techniques for Early Rice Production in the South China Rice Region Currently, it is necessary to focus on drought resistance and protecting spring plowing, and to seize the opportunity for transplanting and planting. In the southern region, early rice should be transplanted around Qingming; in the central region, around Guyu; and in the northern region, before "May Day." The following technical measures should be mainly adopted: 1. Apply sufficient basal fertilizer and transplant sufficient seedlings, and apply tillering fertilizer early and heavily. On the basis of applying good seedling-departure fertilizer to the seedling field, apply 30 kg of ordinary superphosphate, 7.5 kg of potassium chloride, and 25 kg of ammonium bicarbonate per mu as basal fertilizer. Where conditions permit, apply 1000-1500 kg of high-quality farmyard manure per mu. Throw or transplant 21,000-25,000 hills per mu; for hybrid rice, two seedlings per hill (two grains), and for conventional rice, 4-6 seedlings per hill. 5-7 days after throwing or transplanting, apply 5-6 kg of urea per mu as tillering-promoting fertilizer; 12-15 days after throwing or transplanting, apply about 7.5 kg of urea and 7.5-10 kg of potassium chloride per mu, or 12.5-15 kg of compound fertilizer per mu as strong-tillering fertilizer.

Processing Methods and Technical Key Points for Licorice Olive
The raw material used for licorice olive is also olive base, with the same processing technique as chili olive, only the formula is different, and of course the flavor is different too. The processing technique is as follows: 1. Raw material treatment: Desalt the olive base. Since the aim is to highlight the licorice flavor, too much salt should not be left during desalting; generally a slight saltiness is sufficient. After desalting, drain the water or bake until semi-dry for later use. 2. Licorice liquid preparation: Use 5% licorice liquid, that is, for 50 kg of olive base use 2.5 kg of licorice, add 50 kg of clean water, boil down into 20-25 kg of licorice liquid, filter and set aside.

Detailed Explanation of Key Techniques for Artificial Cultivation of Licorice
Licorice, also known as sweet grass, is a perennial herbaceous plant of the Fabaceae family. Its rhizome is used as medicine and has a wide range of applications. In recent years, medical workers in Japan and other countries have discovered that licorice has an inhibition rate of up to 98% against the AIDS virus and has strong immune function. The techniques for artificial cultivation of licorice are introduced below: 1. Cultivation methods. 1. Site selection and land preparation: Licorice mostly grows in dry calcareous soil. It prefers dry conditions and is cold-tolerant, so it is advisable to choose loose sandy soil with a low groundwater table and good drainage for planting. In this kind of land, the main root tends to extend downward, and the roots are straight and rich in powder. After the land is selected,
