How to control subsurface pests in upland rice? A full breakdown of practical techniques
In recent years, with the application and promotion of dry-raised transplanting techniques, upland rice cultivation in Gejiu City has become a new highlight of economic growth in mountainous rural areas. How to do a good job in controlling subsurface pests is an important technical measure for developing upland rice production and ensuring increased yield and income. The common subsurface pests of upland rice mainly include white grubs (the larvae of scarab beetles), wireworms (the larvae of click beetles), mole crickets, and cutworms (cut worms). These pests live in the soil during their damaging period, feeding on seeds, young sprouts, roots and stems, causing missing plants, gaps in rows, or

Qinghai Successfully Introduces a New Fish Species from Russia
The new fish species introduced from Russia for trial breeding - the whitefish (Coregonus peled) - will be promoted on a large scale in Qinghai Province. The introduction of this "foreign fish" has not only broken the previously rather monotonous aquaculture pattern in the province, but also moved Qinghai's fisheries one step closer to the international market. In order to make the whitefish breeding and cultivation technology more mature in the province's aquaculture sector, Qinghai Province recently invited Alexander Ivanovich Litvinenko, president of the Research Academy of the Siberian Fisheries of the Russian Federation and academician of the Russian Academy of Sciences, to visit Qinghai for inspection and technical analysis, and to provide market information.

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

What precautions should be taken when processing snake venom? A full breakdown of the key operational points
1. Pay attention to safety when extracting and processing snake venom. To strictly prevent venomous snakes from injuring people, the movements for releasing the snake during and after venom extraction must be quick. When returning a snake that has been milked to its cage, first place the snake's body inside, and when the snake's head approaches the edge of the container opening, let go quickly. If you cannot withdraw your hand in time when releasing the snake, you can easily be bitten by the snake striking back. 2. Venom extraction equipment must be strictly sterilized. 3. If the venomous snake clamps onto the vessel and will not let go, you may gently swing the snake's trunk; if it still will not release its bite, you may gently twist its neck, or use a small stick or your finger to stimulate the snake's cloaca. Never pull hard

Detailed Explanation of Full-Sun Nursery Technique for Hardwood Cuttings of Dawn Redwood
Dawn redwood (Metasequoia glyptostroboides) cutting propagation mostly uses shading methods. This requires shade netting and daily uncovering and covering of the shade shed. Experimental research on full-sun nursery of dawn redwood hardwood cuttings shows that with appropriate methods, the survival rate generally reaches over 90%. The method is described below: Fine land preparation. The nursery site needs flat terrain, deep soil, and convenient drainage and irrigation. Generally, the land is deep-plowed before winter, and after thawing the soil is broken up fine and leveled flat, with 10 to 15 kg of phosphate fertilizer applied per mu, bed width 1.5 to 1.7 m, bed length depending on the number of cuttings, row spacing 12 to 15

What are the main pests and diseases of dawn redwood (Metasequoia glyptostroboides)? A full analysis of control methods
Damping-off (seedling blight): after leaf fall in autumn, promptly clear away and dispose of fallen leaves, then spray the ground with 3-5Be lime-sulfur mixture. Dawn redwood red blight: immediately after the plum rain season ends, spray the canopy with 1% Bordeaux mixture 4-5 times, once every 10-15 days, to control the occurrence of the disease. Tortricid moths: the best control period is the early stage of damage when the larvae emerge from overwintering (early to mid-April); 50% fenitrothion, 40% dimethoate, 80% dichlorvos and pyrethroid insecticides can be used; in dry seasons (July and August) when outbreaks occur

Rice carefully bred for 6 years finally yields a high-quality new variety
A kilogram of rice sold for a high price of 188 Hong Kong dollars?! A reporter learned yesterday at the provincial agriculture and forestry crop breeding research summary meeting that this was a sales record once set by the Ezhong No. 5 rice bred in our province. Ezhong No. 5 rice is the fruit of 6 years of selective breeding by scientific and technical personnel in our province. According to the introduction, He Shengqiu of the Rural Science and Technology Division of the Provincial Department of Science and Technology found the rice very delicious when visiting abroad in 1998, so he brought back 107 grains of rice and handed them to Chen Yiyi, a researcher at the Provincial Academy of Agricultural Sciences. Chen Yiyi treasured them like a precious treasure,
