Rice quality amylose tester successfully developed through the 948 Program
To fundamentally improve the current rice quality, namely the amylose content of rice, in 2001 the Ministry of Agriculture included the "Rice Quality Amylose Tester" project in the "948" Program. Organized and implemented by China Agricultural University, the project aimed to develop, through this research, a high-quality paddy quality testing instrument suitable for all stages and all levels. Under the leadership of project leader Professor Jia Guiru, Director of the Department of Applied Physics at China Agricultural University, the project has now been completed and has achieved remarkable results. It is reported that the rice

New cotton variety Suza 3 successfully developed in Jiangsu
The new cotton variety "Suza 3", jointly bred by the Institute of Industrial Crops of the Jiangsu Academy of Agricultural Sciences and other institutions, has been successfully developed and recently passed national new variety approval in Jiangsu Province. It is reported that this is Jiangsu Province's first two-gene transgenic insect-resistant hybrid cotton. Tests show that it has strong resistance to common pests such as the cotton bollworm and the pink bollworm. According to experts, at present the insect-resistant cotton in the cotton region of China's Yangtze River basin generally has only a single insect-resistant gene - the "BT insect-resistant gene", while Suza 3, in addition to containing the above gene, also has the "C

Proper drought and disease prevention management during the garlic scape development period
The garlic scape development period is the reproductive growth stage of garlic, mainly including the flower bud differentiation stage and the scape elongation stage. The differentiation of flower buds and bulbils is a critical period in garlic growth and development, and smooth differentiation helps increase yield. The scape elongation stage refers to the period from when the scape begins to elongate until the scape is harvested after the tail-flicking stage, about 30 days. During the garlic scape development period, flower bud differentiation requires temperatures below 10°C; the scape elongation stage requires an optimal temperature of 12°C-18°C. If the temperature is too low, the scape elongates slowly, affecting yield; if the temperature is too high, the scape elongates quickly, the fiber content increases, and quality deteriorates.

What are the causes of cotton abortive development and the remedial measures
Cotton abortive development occurs every year. So-called abortive development means that cotton has lost its normal reproductive function, that is, it only flowers but does not set bolls, or it flowers heavily but sets few bolls. The causes are first of all climatic factors, secondly the blind and indiscriminate introduction of cotton varieties, and thirdly cultivation methods that are incompatible with climate change. According to records, when the temperature exceeds 35°C, pollen development becomes deformed and normal pollination cannot occur; sustained drought then intensifies the shedding of squares and bolls. In addition, in mid-August some cotton areas experience a continuous week of rainy weather, which also makes it difficult for cotton to flower and pollinate normally.

What conditions do edible fungi need for growth and development?
Understanding the nutritional and environmental requirements for the growth and development of edible fungi, creating suitable environmental conditions during cultivation, and cultivating mushrooms scientifically are the only ways to achieve high yields and increase profits. 1. Nutrients needed for the growth of edible fungi Carbon, nitrogen, mineral elements and auxins are the nutrients essential for the growth of edible fungi; wood, sawdust and the like are rich in cellulose, hemicellulose and lignin, and are the carbon nutrition needed by edible fungi; wheat bran, rice bran, soybean cake meal, cornmeal, urea and the like contain abundant nitrogen and are the nitrogen nutrition needed by edible

What to Do When Cattle and Sheep Develop Acute Bloat? A Detailed Guide to Emergency Measures
When cattle and sheep consume large amounts of peanut vines, pea vines, alfalfa, or other legume stems and leaves, or dew-covered grass, they are prone to developing acute gastrointestinal bloat. For severely affected animals, the first step should be to release gas and reduce pressure. After venting, inject vegetable oil or paraffin oil through the trocar opening: 20-40 ml for cattle and 10-15 ml for sheep; Lysol may also be injected: 15-20 ml for cattle and 5-10 ml for sheep. To stop fermentation of rumen contents, administer orally the clear supernatant of 10% quicklime water: 500-1500 ml for cattle and 100-50 for sheep

Analysis and Reflections on the Disease Development Trends of Laying Hens and Broilers
At present, with the scaling up and intensification of poultry farming, poultry diseases are gradually tending toward younger age of onset and increasing complexity, especially diseases of laying (and meat) chickens, which are becoming more and more complex. Once an outbreak occurs, it is very difficult to eradicate, greatly reducing economic returns. The following is a summary of the new characteristics of disease epidemics in laying (and meat) chickens during production, for the reference of fellow farmers. I. Tendency toward younger age of onset and early disease onset: respiratory symptoms appear as early as 3-5 days of age in meat poultry, manifesting as slight nasal shaking and coughing, especially after the first vaccination with the small triple vaccine, due to immune

A Detailed Explanation of the Origin and Development History of Black Tea ⟧2⟧Black tea originated in the Ming Dynasty in the 16th century. During the tea manufacturing process, it was discovered that sun-drying could replace the fixing (kill-green) step
Black tea originated in the Ming Dynasty in the 16th century. During tea manufacturing, it was discovered that sun-drying could replace fixation (kill-green), and after rolling the leaves turned red, thus producing black tea. The earliest black tea production began with Souchong black tea in Chong'an, Fujian. In the Qing Dynasty, Liu Jing's "Pian Ke Yu Xian Ji" records: "At the ninth bend of the mountain there is Xingcun town, where tea experts gather. Tea produced elsewhere in the province such as Shaowu and Jiangxi Guangxin, with black leaves and red soup, locally called Jiangxi Wu, is all privately sold to the various firms of Xingcun." After the appearance of Xingcun Souchong black tea, Congou black tea gradually evolved. In the 1920s, India crushed tea leaves during processing to make broken black tea, and in the 1950s our country also began trial production of broken black tea.

What are the prospects for snake farming? An introduction to the development prospects of snake farming
Because snakes have significant economic value, many people, directly driven by profit, have taken up professional snake catching as a trade to gain substantial economic benefits. Therefore, it is recommended that the relevant departments strictly crack down on and ban this destructive and predatory illegal behavior, and resolutely stop it. In this way, the sharp decline in the natural population of wild snakes can be reduced, in order to prevent severe damage to the ecological environment and cause even greater losses that harm future generations. Therefore, active and effective protection measures should be taken to promote the recovery and expansion of snake populations as quickly as possible in a short period of time, and restore the ecological balance necessary for humanity.
