  • Key Technical Points for Harvesting and Processing Button Mushrooms

    The right time to harvest mushrooms is when the partial veil has not yet broken, the cap has not yet opened, and they have reached the size required by purchasing specifications. Harvesting too early results in small mushrooms and low yield; harvesting too late inhibits the formation and growth of the next flush, prolongs the growing cycle, and also affects mushroom quality. This is especially true when the temperature is relatively high (around 20°C) and there is a heavy flush, as the mushrooms very easily become thin mushrooms or open-cap mushrooms. For commercial mushrooms intended for canning, they generally must be harvested promptly once the cap diameter reaches 2-4 cm. Normally they are harvested once a day, but during the peak production period they must be harvested twice a day to prevent the caps from opening and

  • Button Mushroom Spawning Methods and Technical Key Points

    (1) Spawning date. In each region, an appropriate spawning period must be chosen according to local climatic conditions. The standard for the optimal spawning period is: during the mycelium-running stage of the compost, the natural temperature should be 24-26°C as far as possible. In the Yangtze River basin area, the spawning period is in early to mid-September; in Shanghai and areas near Shanghai, the optimal spawning period is September 8-12. If spawning is too early, temperatures above 28°C are often encountered after spawning, causing the spawn not to germinate and to die; if spawning is too late, the number of days suitable for fruiting is shortened, making it difficult to obtain high yields.

  • How to cultivate Schisandra chinensis? Detailed explanation of planting methods and technical key points

    Schisandra is divided into southern Schisandra and northern Schisandra, both belonging to the Magnoliaceae family. They are perennial deciduous herbaceous plants, and their roots, bark, and stems can all be used as medicine, with very high economic and medicinal value. The following introduces new techniques for cultivating Schisandra: For seedling raising, first wash the fruit with water and remove the shriveled and thin fruits. In early February, soak the fruits in warm water for 3 days to 5 days, rub off the pulp, select plump seeds, then mix them with three times the amount of wet sand and bury them outdoors. The pit depth is about 0.6 m, and the diameter can be determined according to the amount of seeds. Pile

  • Control Methods and Technical Key Points for Soybean Bacterial Blight

    Soybean bacterial blight is a disease that occurs commonly in soybean-growing regions, reducing the percentage of fully filled seeds, lowering the 100-seed weight, and decreasing both quality and yield. Leaf lesions are initially round, brown to dark brown; as the lesions enlarge, the center turns black, the lesions do not appear raised, and diseased leaves drop easily. Lesions on stems and pods are brown and round, later becoming spindle-shaped. The seed surface is coated with a layer of bacterial slime, often appearing at one end of the seed, and its shape closely resembles a "frog eye." Diseased seeds are shrunken, and the pathogen overwinters on diseased leaves, stems, pods and seeds.

  • Key Technical Points and Management Methods for Winter Soybean Cultivation

    1. Sowing time. The sowing window for winter soybeans is quite flexible; yields do not differ noticeably when sowing from early April to early June. In practice, to ensure winter soybeans obtain a suitable stand of basic seedlings, in addition to correctly determining the number of hills per mu to provide the density basis, sowing should generally be done during the period before the corn canopy closes, so that the soybean seedlings have already formed the necessary vegetative mass before shading intensifies, which helps ensure the basic seedling stand. In strip-planting areas, it is best to sow together with corn or slightly later, that is, in mid-to-late April; in sole-cropping areas after the small spring crop, it is best to sow in early-to-mid May. 2. Planting method. Winter soybean planting method

  • Key Technical Points for Spring Soybean Sowing in a Year of Severe Drought in Northeast China

    Current drought situation in Northeast China and technical guidance for spring soybean sowing: I. Precipitation and temperature conditions last winter and this spring. In the autumn and winter of last year, the drought in Northeast China was severe, precipitation was lower than normal, and soil moisture was insufficient. From January to October 2007, the average precipitation in Heilongjiang Province was 402 mm, 20% less than the same period in previous years. In addition, this year's widespread "dry sealing of the soil" at the onset of winter was not conducive to soil moisture conservation. Since the beginning of winter, precipitation in southern Qiqihar, most of Daqing, the Hegang area, and some counties and cities in Jiamusi has been more than 90% less than the same period in previous years; other areas have had 10% to 90% less. In January 2008, the average precipitation across Heilongjiang Province was only 0.1 mm, 97% less than the same period in previous years, with most of the Songnen Plain and the western Sanjiang Plain receiving no precipitation at all for the entire month. After entering February, precipitation in various places continued to remain low. Snow depth across Heilongjiang Province also dropped significantly. Compared with the same period in previous years, snow depth in most areas of the province was about 25 cm less. In 2008, the area of cultivated land affected by drought before sowing in Heilongjiang Province may reach 50 million mu. In addition, the continuous warm winter was extremely favorable for soybean pathogens and pest eggs to survive the winter safely, and soybean diseases and insect pests may occur more heavily this year. The spring drought situation in Inner Mongolia is similar to that in western Heilongjiang Province.

  • What are the key technical points of pig health inspection?

    At present, pig production in China is still dominated by smallholder backyard farming. However, because most pig raisers lack scientific pig-farming knowledge and concepts, the level of technology in production and management - including pig breeds, feed formulation, feeding management and disease prevention and control - is very low. Pig production has long suffered from problems such as slow weight gain, low feed conversion efficiency, low profitability and even losses. Keepers and veterinary technicians should patrol and observe the health of the herd every day and deal with any problem promptly. To properly check whether a pig herd is healthy, the following technical points generally need to be mastered:

  • Key Technical Points and Detailed Explanation of Epidemic Prevention Methods for Swine Disease Immunization

    Reference Immunization Program 1. Vaccines Recommended for General Inoculation 1.1 Classical Swine Fever Immunization: Newborn piglets receive their first vaccination with the conventional dose of lapinized attenuated classical swine fever virus vaccine at 20 days of age. (It is best to promote zero-time pre-immunization.) Piglets at 50-60 days of age receive the routine second immunization. Selected replacement pigs receive a third immunization before participating in mating. 1.2 Swine Paratyphoid Immunization: The entire herd of adult and replacement pigs are immunized at conventional doses in March of spring and September of autumn.
