How to control potato ring rot? Key points of control techniques in high-altitude cold regions
Potato ring rot is extremely widespread, occurring in almost all areas where potatoes are cultivated, and is especially severe in the Northeast region, where it can reduce potato yields by 20%-30%. It is a very serious bacterial disease that not only affects potato yield but also affects potato quality, with poor edibility, causing serious economic losses to agricultural production. Therefore, management should be strengthened and timely prevention should be carried out. 1 Distribution and harm Potato ring rot occurs in Asia, Europe, North America, South America and other regions, and in China it is found throughout the country

Rice cultivation in cold regions requires water-saving irrigation, selection of improved varieties, making the most of accumulated temperature, and growing strong seedlings
Heilongjiang Province is located in a high-cold region, where heat and water resources are relatively scarce, annual atmospheric precipitation is extremely unevenly distributed, spring is windy with little rain, and drought is quite severe. The author discusses how to achieve water-saving, high-quality, and high-yield rice cultivation in cold regions. 1. Selecting excellent varieties is the prerequisite for ensuring high-quality and high-yield rice. The varieties that rice farmers plant directly affect the quality and yield of rice. Therefore, in production, varieties with a suitable maturity period, excellent quality, stable and high yield, and strong stress resistance should be selected. First, select varieties that have passed national approval, been named, and promoted, which can ensure relatively stable rice traits, steady and rising yields, and safe and reliable use; second, introduce varieties with suitable maturity periods according to different accumulated temperature zones, and never introduce varieties across zones; third, pay attention to seed quality, and select first-grade improved seeds with a purity above 98%, a germination rate above 90%, and a moisture content no higher than 14% for production use; fourth, purchase seeds from nationally certified seed companies, research institutes, and agricultural colleges, and eliminate blind planting; fifth, in actual planting, unify varieties as much as possible, plant in contiguous fields, form scale, and achieve industrialized planting.

Cold Red Pear
Bred by the Jilin Provincial Fruit Tree Research Institute from Nanguo Pear × Jinsu. The fruit is round, with an average single-fruit weight of 170-200 g and a maximum of 450 g; when ripe, the skin is mostly waxy, the background color is bright yellow, and the sun-exposed side is vivid red, giving a beautiful appearance. The flesh is fine, crisp and juicy, with few stone cells and a small to medium-sized core; it has a rich sweet-sour taste and the aroma of Nanguo Pear, contains 14%-16% soluble solids, and is of superior quality; the fruit ripens in late September. It can be stored for more than 5 months in an ordinary fruit cellar, and the flavor is even better after storage; the tree is vigorous and grows strongly, with a high sprouting rate and medium branching ability

How to Tell the Difference Between True Colds and False Colds in Dogs
True colds in dogs are systemic symptoms characterised mainly by inflammation of the mucous membrane of the upper respiratory tract. Colds generally occur most often in early spring, late autumn and when the climate changes abruptly. The cause is mostly sudden exposure to cold stimulation, such as being hit by a draught in winter, sleeping outdoors in the cold season, getting caught in the rain, or not drying a dog's coat promptly after bathing. The main symptoms of a dog with a cold are: the sick dog is depressed, has reduced or no appetite, the conjunctiva is congested and red, and the eyes are photophobic and run with tears. There is coughing, the nasal discharge is purulent, breathing speeds up, body

Comprehensive High-Yield Cultivation Techniques for Soybean in High-Cold Regions
Soybean is the main crop in the Jiamusi region of Heilongjiang Province, with an annual sown area of more than 900,000 mu, accounting for more than 75% of the total sown area. For a long time, due to the cold climate, short frost-free period, insufficient accumulated temperature, and lack of suitable varieties, soybean yields have remained stagnant at only about 150 kg, and in disaster years even less than 100 kg. In view of this, based on the climatic characteristics of Heilongjiang Province, we have developed several techniques suitable for soybean

Detailed Explanation of the Design Method for Phalaenopsis Forcing Cold Rooms
Forcing Requirements The vegetative growth temperature for Phalaenopsis is usually 20°C to 30°C, while the temperature required for forcing varies by strain: for the first strain type, the reproductive growth temperature is the same as the vegetative growth temperature, with daytime temperatures maintained below 30°C and nighttime temperatures lower than daytime temperatures being sufficient to meet the forcing requirements

Qing'an's 700,000 mu of rice adopts cold-region dry seedling cultivation and controlled irrigation technology for water saving and high yield
The controlled irrigation, water-saving and high-yield technology for cold-region dry seedling rice has been successfully tested in Qing'an. This year, 700,000 mu of rice in this county are using this technology. According to expert calculations, it saves about 450 cubic meters of water per mu, saves 11.2 yuan in pumping costs, and increases yield by an average of 22 kg per mu. In recent years, through the trinity approach of "engineering water saving, mechanism water saving, and technical water saving," Qing'an has reduced irrigation water per mu from nearly 1,000 cubic meters to 500 cubic meters. Over 10 years, it has expanded the paddy field area from 640,000 mu to 1.17 million mu, accounting for half of the cultivated land area. Last year

Symptom Identification and Prevention Methods for Potato Cold Injury
During plant growth or during tuber storage, if the air temperature or soil temperature is too low (above freezing), the plant will suffer cold injury. The degree of cold injury varies with the temperature. 1. Leaf symptoms At the seedling stage, after the plant suffers freezing injury, the leaves quickly wilt and collapse. When the temperature becomes warmer, the affected parts become water-soaked and turn brown after dying. However, if the plant suffers only cold injury, the above symptoms will not appear. Cold injury occurs at the seedling stage in early spring. The symptoms appear at the top of the seedlings, showing light yellow to light brown at the base of the young leaves. When
