How was the disease-resistant, fragrant and soft rice variety Jiuqi Xiang No. 1 bred?
I. Breeding process 1. Parent selection The internationally renowned rice variety Basmati, a superior rare fragrant-soft line obtained by mutation of Basmati original seed through solar radiation at this institute, and Xiangsimiao No. 2 were mixed and used as the male parent, with the conventional short-stalked, high-yielding, good-resistance and widely adaptable Qingzhen No. 8 as the female parent. 2. Progeny selection After a single plant was selected in the late season of 1991, various types of single panicles with medium-short stalks and plant-grain type similar to Xiangsimiao were selected respectively from the segregating materials of the F2 and F3 generations, then multi-generation selection and propagation and single-plant line comparative trials were carried out.

Rice cancer has met its nemesis: breeding of a disease-resistant new variety succeeds
Since the beginning of this century, rice stripe virus disease has continued to break out over large areas, in severe cases even causing rice farmers to lose their entire harvest. Rice stripe virus disease has been regarded as the "cancer" of rice. "Wuyujing 3", long recognized by the market as the main rice variety with the best taste and quality in Jiangsu Province and surrounding areas, has seen its planting area plummet in recent years because it is highly susceptible to rice stripe virus disease. Some stripe virus-resistant varieties either have shortcomings in yield and yield stability, or have not been fully recognized by the market for their rice quality. Rice farmers

Adding rice husk to mushroom casing soil brings better planting benefits
In conventional mushroom cultivation management, casing soil is a technically demanding task. There are special requirements for the casing soil's texture, soil aggregate structure, aeration, and water retention and holding capacity. In particular, when making large, medium, and small casing soil particles, it is both labor- and time-consuming, and the labor intensity is high. To effectively solve these problems, the author has repeatedly reformed mushroom casing soil technology since 1990, and finally determined to use surface humus soil from within forest stands or paddy field plough layer soil (sandy loam or clay loam are both acceptable) mixed with 5% fresh rice husk

How to Select and Prepare Land for Planting Licorice
Usually, sandy soil that is fertile, loose in texture, well-drained and low in salinity and alkalinity is chosen for planting licorice, and it requires a deep soil layer and a low groundwater table. In North China, Northeast China and Northwest China, licorice should be cultivated on sand dune areas or on high-lying alluvial soil on both banks of rivers; this kind of licorice is rich in powder, low in fiber and strong in sweet taste; saline-alkali land should not be chosen, otherwise the cultivated licorice will have short main roots and many branches, with rhizomes growing horizontally on the surface, thin and weak, and the product will be light in weight, low in powder and not strong in sweet taste. Choose sandy loam with a deep soil layer; as long as it is plowed about 30 cm

What to do about pigeon dysentery? It can be treated with the Chinese herb licorice
When a pigeon suffers from dysentery, its droppings are as thin as water, green with a yellow tinge. The sick pigeon huddles in the coop, drinking large amounts of water but not eating, and its condition worsens by the day. Buy licorice, mash it up and administer it to the sick pigeon by mouth, and also soak licorice in water for the sick pigeon to drink. The next day the droppings had already changed from thin to dry. Continue treating with licorice, and in less than a week the sick pigeon can recover. According to "Compendium of Materia Medica" by Li Shizhen, "Licorice, sweet and neutral in nature and flavor, mainly treats cold and heat pathogenic qi of the five zang and six fu organs, and resolves a hundred toxins," and "treats red and white dysentery, and taken it works immediately."

Detailed Explanation of Key Points for Artificial Cultivation Techniques of Chinese Licorice
Licorice, also known as sweet root and dense grass, has 23 varieties worldwide. China is the country with the most licorice distribution, with 12 varieties. Ural licorice (i.e., Chinese licorice) is the most widely distributed, highest-yielding and best-quality licorice species among the six licorice species listed in the pharmacopoeia of China, and has long enjoyed a high reputation in the international market. Licorice is a perennial herbaceous plant of the Fabaceae family, and its roots and rhizomes have the effects in traditional Chinese medicine of harmonizing various medicines and neutralizing a hundred toxins. China has the sayings "nine out of ten prescriptions contain licorice" and "no prescription is complete without licorice," so it is called the king of Chinese herbal medicines. Licorice

Symptoms and Control Methods of Brown Spot Disease in the Medicinal Plant Licorice
Licorice, scientific name Glycyrrhiza uralensis Fisch., also known as meicao and micao, is a perennial herbaceous plant in the Fabaceae family. Its roots and rhizomes are used as medicine. It has the effects of harmonizing the middle and relieving urgency, moistening the lungs and detoxifying, and harmonizing various medicines. It is produced in Inner Mongolia, Gansu, Shanxi, Shaanxi, Liaoning, Jilin, Heilongjiang, Hebei and other provinces. The symptoms mainly damage the leaves. The lesions on the leaves are round or irregular, 1-3 mm in size, with a grayish-brown center and brown edges, and grayish-black mold-like substances, namely the pathogen's conidia, grow on both sides.

Occurrence and Control Methods of Root Rot in the Medicinal Plant Licorice
Symptoms The disease mainly affects the rhizome and roots. After infection, the stems and leaves of the aboveground part gradually turn yellow and wither, and the rhizome becomes yellow-brown to dark brown, sunken and rotten. The pathogen Fusarium sp. is a species of Fusarium, belonging to the Deuteromycotina fungi. For the morphological characteristics of the pathogen, transmission routes, disease conditions, and control methods, see Astragalus Root Rot.

In the field of licorice research and development, our country has become the leader
It was recently learned at the founding conference of the Special Committee on Chinese Materia Medica Pharmaceutics of the World Federation of Chinese Medicine Societies and the International Symposium on Chinese Materia Medica Pharmaceutics that our country has successfully applied chiral catalysis technology to the purification of the active ingredients of licorice, increasing it from 3% to 97%, greatly saving medicinal materials. At the same time, following the recent introduction of the Class I new drug and chiral liver drug "Tianqing Ganmei", this shows that our country has already taken a world-leading position in the research, development and innovation of licorice preparations. Chiral technology works by scientifically adjusting the chemical structure arrangement
