Processing Methods and Technical Points for Mantis Shrimp
Mantis shrimp is also called shrimp crawling child, scientific name Oratosquilla oratoria. The body is flat, the pleopods and tail fan are well developed, the carapace on the front part of the body is very thin, and the rear part is thicker, the rostrum is not prominent, the carapace is wide and round, the first pair of thoracic legs is pincer-like, asymmetrical, with sexual dimorphism, and there are two protrusions on the inner margin. Mantis shrimp is the main bycatch of fixed nets in the Bohai Sea, with the spring fishing season from April to July and the autumn fishing season from October to November. It can be processed into frozen boiled mantis shrimp with shell and frozen boiled headless mantis shrimp. I. Processing of frozen boiled mantis shrimp with head 1. Quality conditions:

Detailed Explanation of Key Technical Points for Lambing Assistance in Spring
Every year in February and March, it is the peak season for ewes giving birth. To assist ewes during lambing, four key points must be mastered: First, pre-lambing preparation. At this time the weather is turning warm but still cold, so a lambing room must be prepared before the ewe gives birth, keeping the temperature above 5°C, and disinfecting with 2%-4% Lysol solution or 15%-20% wood ash water. The floor of the lambing room should be covered with dry grass or sand to keep it dry. At the same time, some disinfectants (such as alcohol, iodine tincture, etc.) and other tools should be properly prepared. Second, normal delivery. When the ewe goes into labor, the lamb first

Detailed Explanation of Key Technical Points for Increasing Spring Tea Yield and Improving Quality
Delaying light pruning: Conventional light pruning of the tea canopy is carried out from December in winter to February of the following year. Practice has shown that doing so has three drawbacks: first, the branches are prone to frost damage after pruning; second, the overwintering buds are cut off, delaying the sprouting time of spring buds; third, the nutrients already accumulated in the branches on the tea canopy surface are cut away, affecting the sprouting vigor of spring buds and the growth of thick strong branches, ultimately affecting spring tea yield and quality. Therefore, the pruning time should be after the frost period, preferably so that the first spring tea can be picked 30 to 40 days after pruning. Advancing topdressing: Conventional topdressing is mostly carried out in early to mid-March, when spring buds

Pruning Methods and Technical Points for Aging Tea Plants
1. Heavy pruning: Heavy pruning is suitable for semi-aged tea plants and for tea plants that decline before their time; their age is not necessarily very great, and most main branches still retain a certain capacity for growth. For such tea plants, heavy pruning can be carried out to renew and rejuvenate them, generally cutting away 1/3 to 1/2 of the canopy. 2. Frame cutting: For very aged tea plants, even increased fertilizer application can hardly raise yields. Such tea plants are better renewed by frame cutting, that is, around Great Cold (Major Cold) sawing (or cutting) off all branches and trunks at a height of about 15 cm above the ground and regrowing the bush. Tea plants subjected to frame cutting or heavy pruning should all be treated on the basis of deep plowing and sufficient basal fertilizer.

Key Technical Points for Pollution-Free Tea Plant Cultivation and Management
I. Cultivation and Management of Tea Gardens in the Young Stage 1. Deep plowing to improve soil. Water is an important component of the tea plant organism. Deep plowing to improve the soil can store water and retain moisture, ensuring good root growth and development of tea plants. During deep plowing, do not mix up the topsoil and subsoil; place them separately in the inner side and outer trench. When backfilling, put the topsoil at the bottom of the trench and spread the subsoil on top. The depth of deep plowing must be more than 50 cm. 2. Transplanting. The transplanting time should be determined according to local conditions and varieties, generally from late February to mid-March in early spring, or from mid-October to early November in late autumn and early winter. It is advisable to choose cloudy days

How to sow Panax notoginseng? Detailed explanation of sowing methods and technical key points
Sowing rate of Panax notoginseng per mu: with a row spacing of 7 cm x 7 cm, about 75,000 to 90,000 seeds; with 10 cm x 7 cm, about 50,000 to 60,000 seeds; with 10 cm x 10 cm, about 33,000 to 40,000 seeds; the land utilization area is 50% to 60%. The sowing period is from early to late November, and no later than January of the following year. Before sowing, first make a hole-punching template from wood, that is, on a wooden board 1.3 to 1.5 m long and about 30 cm wide, fix several round

Harvesting and Processing Methods of Panax notoginseng and Key Technical Points
Harvesting can be done after more than three years of cultivation. Harvesting is divided into two periods: Panax notoginseng harvested in July-August is called "spring notoginseng," and the notoginseng harvested after the flower stalks are removed has the best quality and also high yield; Panax notoginseng harvested from December after the Beginning of Winter to January of the following year is called "winter notoginseng," which has poorer quality and also low yield. After digging out, remove the aboveground stems and wash off the soil. After cutting off the rhizome (sheep intestine head), branch roots, and removing the fibrous roots, it is called "touzi." Repeatedly sun-dry and rub the touzi to make it firm until completely dry, which is "maohuo." Then

Detailed Explanation of the Key Technical Points for Introducing and Cultivating Gynura segetum
Gynura segetum (Lour.) Merr. is a plant in the Asteraceae family, also known as Japanese gynura, white panax notoginseng, blood-dispersing herb, blood-dispersing elixir, blood-breaking elixir, blood peony, etc., and its traditional Chinese medicine name is tu san qi. Its tuberous roots or the whole plant are used medicinally, with effects such as promoting blood circulation, reducing swelling, detoxifying, dispersing blood stasis, and stopping bleeding. It is mainly used for traumatic injuries, carbuncles, sores, and ulcers, venomous snake bites, external bleeding, hematemesis, hematuria, hemafecia, functional uterine bleeding, and other conditions. It is mainly produced in Yunnan, Guizhou, Guangdong, Guangxi, and other places, and is rarely cultivated in the north.

Key Technical Points for Log Cultivation of Reishi Mushroom (Ganoderma lucidum) in Greenhouses
Technical Introduction: Reishi mushroom (Ganoderma lucidum) grows on broadleaf tree stumps or decaying conifer wood, forming fruiting bodies in summer and autumn. Reishi mushroom is both a saprophytic fungus and a facultative parasitic fungus. The optimum temperature for the growth of Reishi mushroom mycelium is 25°C. The optimum temperature for primordium differentiation and fruiting body development is 25-28°C. During the mycelium growth stage and fruiting body development stage of Reishi mushroom, the suitable moisture content of the substrate is 55-60%; the relative humidity of the air needs to reach 90-95%. Reishi mushroom is an aerobic fungus; when the carbon dioxide concentration in the air exceeds 0.1%, the fruiting bodies of Reishi mushroom will become deformed,

How are grafted Schisandra chinensis seedlings cultivated? A detailed explanation of the key technical points
Schisandra chinensis is a wild fruit tree distributed in Northeast China. Its fruit can be used both as medicine and for brewing wine and making juice to produce beverages. It is a multifunctional, multi-purpose wild economic plant with high development and utilization value and very broad application prospects. Since the 1990s, in response to the continuous decline of wild Schisandra chinensis resources and growing market demand, our institute has carried out research on domesticated high-yield techniques and new variety selection and breeding, summarized a complete set of domesticated high-yield cultivation techniques mainly including artificial orchard establishment, shaping and pruning, soil management, and pest and disease control, and bred a new
