Breeding and Application of Tianfengyou 269, a High-Yield, High-Quality, Multi-Resistant Hybrid Indica Rice
1 Breeding Process Tianfengyou 269 (formerly named Yanyou 269) is a new high-yield, high-quality, multi-resistant three-line hybrid indica rice combination bred in 2002 by the Institute of Agricultural Sciences of the Coastal Region of Jiangsu, by crossing Tianfeng A, developed by the Guangdong Academy of Agricultural Sciences, with the restorer line Yanhui 269, which was self-bred by our institute. The self-bred restorer line Yanhui 269 was produced in the summer of 1995 by making a cross with Yanhui 559 as the female parent and Yanhui 469 (an intermediate material of our institute) as the male parent, obtaining 26 hybrid seeds, which were brought to Sanya, Hainan in the winter of the same year for planting

Pinching Technique for Robinia hispida: Promoting Multiple Blooming Cycles
Robinia hispida, also known as Jiangnan locust, under natural growing conditions blooms only once a year. A large amount of nutrients is devoted to shoot growth, and water sprouts can reach over one meter. When summer arrives, strong winds can blow the tender shoots off their growth direction, forming a lopsided crown. This not only reduces the ornamental value of Robinia hispida but also increases the workload of winter pruning. During winter pruning, many branches that have grown rampant for a year are removed or cut back as useless branches, and the cut-back branches will continue to grow rampant the following year. By utilizing the multiple-growth

Detailed introduction to the new multi-resistant cotton variety Duokang Wanza 40
The following variety was developed by Anhui Runhe Cotton Industry Co., Ltd. Duokang Wanza 40: this variety improved the parent lines of Wanza 40 into disease-resistant material through disease-nursery screening, then introduced the BT insect-resistance gene, and was bred into the new combination "Duokang Wanza 40". This combination not only maintains the high and stable yield of Wanza 40, but also has excellent traits such as insect resistance, disease resistance and strong stress resistance. Characteristics: the plant of this variety is tower-shaped, relatively compact, with a plant height of 100 cm. The whole growth period is 128 days, belonging to a medium-maturing variety, with medium-sized leaves, dark green leaf color, and bolls

Cotton shows disease symptoms, integrated control with multiple measures
Symptom identification of cotton Fusarium wilt and Verticillium wilt. Cotton Fusarium wilt can occur throughout the entire growth and development period of cotton, but it occurs more severely at the seedling stage. If favorable conditions occur, it can also break out heavily at the adult plant stage. Sudden wilt type: leaves suddenly lose water, droop and wilt, leaf color is dark green, leaves become soft and thin, the whole plant dries green and dies, but leaves generally do not fall off, and petioles bend. Yellowing type: can occur at both the seedling stage and the adult plant stage. The yellowing type mostly starts from the leaf margins, with part or all of the leaf turning yellow, and finally the leaf dies or falls off, while the petiole

How to Handle Sick Pigs That Do Not Respond to Multiple Drug Injections
In daily veterinary practice, it is common to encounter sick pigs that have been given repeated symptomatic injections of penicillin, streptomycin, analgin and other drugs without any improvement. We suggest the following approach: Basic method: calculated per 30 kg of pig body weight per dose (the same below), dexamethasone sodium phosphate 6 ml, nikethamide 2 ampoules, kanamycin hydrochloride 10 ml, injected intramuscularly separately. For persistent coughing and wheezing, use the basic regimen plus intramuscular injection of 3% ephedrine 2 mg. After 10 minutes, inject sulfadiazine sodium 0.5 mg intramuscularly.

Prevention and Control Methods and Technical Key Points for Common Multiple Diseases in Pigs
The common multiple diseases of pigs mainly include: piglet Escherichia coli disease, transmissible gastroenteritis, epidemic diarrhea, asthma, and piglet hypoglycemia. These five common diseases of pigs seriously affect the normal growth and development of pigs, hinder the development of the pig industry, and often cause massive pig deaths. Therefore, the prevention-oriented policy of prevention and control must be implemented, and careful prevention and treatment must be carried out to take preventive measures, and one must never take it lightly, so as to ensure the smooth development of the pig industry. Piglet Escherichia coli disease Piglet Escherichia coli disease has the following three manifestations: early-onset

Key Technical Points for Diversified Multi-Cropping Three-Dimensional Cultivation of Cotton in the Huaibei Region
Diversified multi-cropping three-dimensional cultivation is a high-yield, high-efficiency agricultural production form and supporting comprehensive technical system that conforms to biological population structure. Developing diversified multi-cropping three-dimensional cultivation can achieve good economic, social and ecological benefits. I. Mechanisms for developing diversified multi-cropping three-dimensional cultivation of cotton in the Huaibei Region. 1. Adapt to local conditions and emphasize efficiency. Three-dimensional cotton cultivation involves multiple crops, multiple factors and multiple disciplines, and is highly time-sensitive, regional, comprehensive and scientific. Therefore, appropriate timing and varieties should be selected for cultivation in combination with the land, climate and other conditions of the Huaibei Region.

Schisandra chinensis has the effect of reversing multidrug resistance in tumors
The crude extract of "Schisandra chinensis" and its active ingredient schisandrin A have a reversing effect on multidrug resistance, and can greatly increase the sensitivity of tumor cells to antitumor drugs. The structure of schisandrin A is different from all known multidrug resistance reversing agents, making it a Chinese herbal medicine with development prospects. This is a "new discovery" disclosed by Liu Gengtao, researcher at the Institute of Materia Medica, Chinese Academy of Medical Sciences, and academician of the Chinese Academy of Engineering, in his academic report at the "Guangzhou Pharmaceutical 2006 Cross-Strait Pharmaceutical (Yangcheng) Forum" held recently.
