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. It has large panicles and many grains, with an average

How does the Super Dry Rice 1 variety perform?
Super Dry Rice 1 is a new super-high-yield dry rice variety bred by the China National Rice Research Institute. Results from plantings in Hangzhou and Hainan show that this dry rice variety has strong stress resistance, high and stable yield, and above-average grain quality, with broad application prospects, especially when planted as an early crop (dry season) in Hainan and South China, where it has considerable yield-increasing potential and great value for development and promotion. The characteristics and key cultivation techniques of Super Dry Rice 1 are briefly introduced as follows: 1. Characteristics of Super Dry Rice 1. 1. Main agronomic traits. Super Dry Rice 1 demonstrated in the Hainan dry season

Gleditsia triacanthos is a new and superior salt- and alkali-tolerant tree species for the Yangtze River Delta region
Gleditsia triacanthos (honey locust), of the Fabaceae family and the genus Gleditsia. A deciduous tree, its branches often bear thorns, its leaves are bright green and usually bipinnately compound, turning yellow in autumn, and its fruit is a large, often twisted pod. It prefers full sun, grows normally in saline-alkali soil, has strong adaptability to soil, can withstand low temperatures below -30°C, and is very cold-hardy. Its crown is large, making it a good shade tree.

Super-healthy watercress developed through genetic technology
Watercress was originally just an ordinary vegetable in the housewife's shopping basket. British scientists used transgenic technology to make watercress rich in the polyunsaturated fatty acids found in chicken and fish, turning it into a "super-healthy" vegetable. The Omega-3 and Omega-6 polyunsaturated fatty acids contained in this transgenic watercress can regulate blood pressure and immune responses and participate in cell signaling activities. Omega-3 is also believed to promote brain development and reduce the incidence of heart disease and rheumatoid arthritis in adults. Seaweed and mushrooms are rich in natural polyunsaturated fatty acids. British Bristol

Detailed Explanation of Super-High-Yield Cultivation Techniques for Single-Season Rice in Northern China
(1) Use plastic film and special non-woven fabric to cover dry-raised rice seedlings, with the seeding rate controlled within 200 grams per sq m. (2) Transplanting spacing in the paddy field: 30 cm x 16.7 cm to 20.0 cm sparse planting, or (40 cm + 20 cm) x 16.7 cm wide-ridge double-row sparse planting. (3) Apply 60-70 kg of standard nitrogen per mu, 10 kg of diammonium phosphate, and 10 kg of potassium sulfate. (4) Intermittent water-saving irrigation in the paddy field alternating shallow water, wet, and dry conditions. (5

What are the characteristics of superior hybrid varieties of Taxus media?
1. 20,000 3-year-old Taxus media seedlings were introduced from Canada, mainly for large-scale production of the raw material for the anticancer drug paclitaxel. Taxus in China grows slowly and has a relatively low paclitaxel content, and as a rare tree species it is listed as a national first-class protected plant. Taxus media has a paclitaxel content of about 0.02% in its branches and leaves, and 0.03%-0.04% in its bark, which is 2-3 times the bark content of 60-year-old Taxus in China, and its growth rate is 3 times that of Taxus in China, so it can be utilized at 3-6 years of age. It has the characteristics of an indistinct

What varieties are first-grade superior varieties of apricots for kernel use?
1. Longwangmao Among the apricot varieties for kernel use currently mainly cultivated in production in China, only Longwangmao is first-grade, and it is called "Longhuang Big Almond" internationally. The fruit is oblate, with an average single fruit weight of 18 g and a maximum of 24 g; the skin is orange-yellow and the flesh is thin; the stone is free. The kernel rate is 17.5%, and the dry stone weight is 2.3 g. The kernel yield is 37.6%, and the average dry kernel weight is 0.8-0.84 g. The kernel is flat and plump, conical with a flat base; the kernel skin is brownish-yellow, and the kernel flesh is milky white, fragrant and crisp in taste, with a slight bitterness. The average yield per tree at 5-6 years old

How good is the Super Large Grain King rice variety?
Zhezao 15 is a super-high-yield early indica rice new line developed by mutagenesis treatment using the super-high-yield genetic advantage of "Zhe 18500". After multi-point trial planting as early rice by the Zhejiang Academy of Agricultural Sciences, the yield generally reaches more than 600 kg per 667 sq m (1 mu). The characteristics and advantages of Zhezao 15 are introduced as follows: 1. Extremely strong tillering ability, low seed requirement. The effective tillers per plant can reach 12-15, and 1 kg of seed per 667 sq m of field is sufficient. 2. Cold tolerance at the seedling stage, disease resistance at the later stage. Strong cold tolerance at the seedling stage, so sowing can be appropriately advanced

Golden-leaf dawn redwood is a new and superior colored-leaf tree species
Dawn redwood (Metasequoia glyptostroboides) is the only surviving species of the genus Metasequoia in the family Cupressaceae. This species was once thought to be extinct, until it was discovered in 1941 in the Lichuan area of Hubei, China, and afterwards this plant was also found successively in the Wanxian area of Sichuan. In 1947, dawn redwood seeds were introduced to the Arnold Arboretum in the United States, and from there spread to botanical gardens around the world. In 1948, "dawn redwood" and its scientific name were formally named, and since then it has enjoyed great fame in China and even the whole
