These practical techniques help late-sown wheat achieve high yields
Because late-sown wheat (wheat sown after mid-October, generally called late-sown wheat) is sown late, it is difficult to achieve full, strong and uniform seedlings, and thus difficult to obtain high yields. However, with proper management, a high yield is entirely possible. 1 Apply sufficient base fertilizer. Late-sown wheat needs 10-15 days from sowing to emergence, which shortens the pre-winter growth period and causes the seedlings to grow in the soil for too long and become weak. Late-sown wheat must be given sufficient base fertilizer, with 3500 kg of high-quality farmyard manure, 40-45 kg of ammonium sulfate, 50 kg of superphosphate and 10 kg of potash fertilizer per mu

Yangdao 6: Breeding and Utilization of a New Medium Indica Rice Variety with High Quality, High Yield and Disease Resistance
Yangdao 6 is a new medium indica variety bred by the Institute of Agricultural Sciences of the Lixiahe Region of Jiangsu, using Yangdao 4 as the female parent, crossed with "Yan 3021", with the F1 seeds subjected to 60CO-gamma ray irradiation mutagenesis, and then developed through continuous directional selection. This variety combines high quality, high yield, disease resistance and wide adaptability, and is an ideal seed source for developing high-quality rice; it has already been demonstrated and promoted on a large scale in Jiangsu, Anhui, Hubei, Shanghai and other provinces and municipalities. Yangdao 6 is also a high-quality restorer line for two-line hybrid rice and three-line Honglian-type hybrid rice, and the formulated "Liangyou Peijiu" and "Yueyou 9

Which diseases cause high fever in pigs without purple patches on the skin?
1. Japanese encephalitis: The body temperature of affected pigs is 40-41°C, with teeth grinding, circling, visual impairment, and blind charging. Sows abort, and boars develop orchitis, which gradually atrophies and hardens, causing loss of breeding ability. For treatment and drug prevention, antiviral preparations such as amantadine and ribavirin combined with interferon, along with traditional Chinese medicine preparations for clearing heat and detoxifying, and antipyretic-analgesic preparations, should be used together, which has a certain therapeutic effect. 2. Pseudorabies: It mostly occurs in piglets aged 1-4 weeks, and piglets over 60 days of age show mild symptoms. Body temperature is 41-42°C. In the early stage of the disease, the pigs are restless and excitable

Comprehensive growth regulation technology for high-density cultivation of cotton variety 81-3
The 81-3 variety has the characteristics of a high boll-setting rate per plant, strong boll retention, disease resistance, high yield and good quality, and is currently the main variety planted by our regiment. At the same time, the 81-3 variety also has the characteristics of weak growth vigour at the seedling stage, gradually strengthening growth vigour at the bud stage, strong growth vigour at the flowering stage, no premature senescence in the late stage, and a rather long growth period. To obtain large-area abundant and high yields under high-density cultivation conditions, it is necessary, on the premise of scientifically and rationally managing water and fertiliser, to coordinate the relationship between vegetative growth and reproductive growth of cotton, and to master the comprehensive growth regulation technology for high-density, high-yield cultivation of 81-3.

Red Pearl is a high-yield Schisandra variety
Dai Shuiping of Fengcheng City, Dandong, in October 2000, introduced 150 seedlings from the Chinese Academy of Agricultural Sciences, and cultivated them with exclusive techniques for four years. They fruited in October 2004. From the 150 plants, 20 were selected that produced 5-10 kg of fresh fruit per plant. Among them, tree No. 1 performed especially outstandingly: robust tree body, dark green leaf color, luxuriant branches and leaves, plump fruit juice, large leaves, thick leaves, disease resistance, standard tree shape, good appearance, 302 clusters of fruit per plant, each cluster weighing 33 g, each berry weighing 1.

Construction of High-Yield Schisandra Orchards and Seedling Selection and Breeding Techniques
Terrain conditions: Different terrains have a considerable impact on cultivated Schisandra. Under natural conditions, Schisandra is mainly distributed on shaded forest edges and open woodlands in mountainous areas, growing naturally with extremely low yields. Through artificial cultivation and 5 years of observational practice, it has been proven that more than 10 hours of all-day sunlight, an open field of view, no major obstacles around, good ventilation and light penetration, access to water, drainage capability, and a soil layer of 50 cm constitute the optimal location. Water source conditions: Schisandra is relatively drought-tolerant. To obtain higher yields and ensure good plant growth, strengthen rapid division of growth cells

Red Pearl Schisandra bears many fruits, with a yield twice as high
Recently, the reporter learned during an interview that Dai Ping, a villager from Fenghuangshan Village, Fengshan Economic Management District, Fengcheng City, has grown high-yield Schisandra. For ordinary varieties, the average fresh fruit yield per plant is usually 2.5-3 kg; while the average fresh fruit yield per plant grown by Dai Ping is 7-8 kg, twice as high as ordinary varieties. This high-yield variety is a Schisandra called "Red Pearl" that Dai Ping purchased from the Institute of Special Animal and Plant Sciences of the Chinese Academy of Agricultural Sciences after consulting several experts. According to Dai Ping, to make Schisandra high quality and high yield, the variety

Experience sharing on high-yield artificial cultivation of Schisandra chinensis
In recent years, as wild resources have declined and production has fallen year by year, the price of the Chinese medicinal herb Schisandra chinensis on domestic and international markets has risen for consecutive years, which has inspired people's enthusiasm for cultivating Schisandra chinensis. According to reports, to achieve high yield and high efficiency in artificial cultivation of Schisandra chinensis, three key links must first be handled well: first, variety selection, purification and improvement must be carried out; second, a period of domestication and adaptation is needed; third, pruning must be strengthened to regulate and control tree vigor. The three are mutually reinforcing and none can be omitted. First, carry out variety selection, purification, domestication and improvement of wild Schisandra chinensis

Detailed Explanation of Key Points for High-Yield Pruning Techniques of Schisandra chinensis
I. Row Orientation The best row orientation for Schisandra chinensis cultivation is a north-south direction, which provides good lighting and ventilation, laying the foundation for stable and high yields. II. Trunk Establishment Schisandra chinensis seedlings grow vigorously in the summer of the year they are transplanted. Select and retain 3-4 healthy lateral vines per plant and train them onto poles. One seedling gets two poles, with two main vines climbing each pole. Cut off the original main stem of the seedling. When each main vine reaches 50 cm in length, pinch the growing tip to establish the trunk, encouraging buds below the cut to grow young shoots (i.e., short fruit branches, also called secondary shoots). When the young shoots reach 30 cm in length, select one healthy shoot and do not pinch
