Ram vasectomy surgery and postoperative treatment and care
Ram vasectomy is the ligation or removal of a segment of the vas deferens (removing a segment is best), and ensuring the ram has good libido after surgery so it can be used for teasing.

Schisandra Hybrid Seed Production Method and Key Operating Points
First, select in the mountains trees with good tree shape, large fruit yield, large clusters, large berries, and abundant overall fruiting, uniform; harvest the seeds and sow them directly for seedling raising; when they enter the full fruiting stage, go into the orchard and select by the same standards. Sow directly in spring, select during the full fruiting stage, and from these select 2 trees with outstanding performance; label them respectively as the male parent and the female parent, keep them far from the production orchard, and arrange pollinator trees in a 2:1 ratio; when the fruit ripens, go into the orchard to observe whether the overall fruiting across the whole orchard is consistent, whether the cluster ratio is standard, and whether there is any phenomenon of large and small berries; the yield per plant should be more than 5 kg, meeting the above standards.

New soybean topping technique for higher yields: operate this way to get a bigger harvest
Soybean terminal buds have strong growth vigor and consume a lot of nutrients. Removing the terminal buds of soybean transfers nutrients to the pods, which helps increase yield. This is especially true for soybean with higher soil fertility and vigorous growth; timely removal of the terminal buds makes the yield-increasing effect even more pronounced. The method for removing soybean terminal buds is: at the early flowering stage, the peak of soybean growth, pinch off the 2-3 cm tender tip at the top of the main stem, so that apical growth is inhibited and nutrients are concentrated for reproductive growth, promoting more flowering and more pod setting, and helping to make the plants shorter and sturdier and enhance stress resistance. Soybean topping should follow the “three

Detailed Explanation of Key Technical Points for Cooperative Rearing of Young Silkworms
As the saying goes: "Rearing young silkworms well means 70% of the harvest." For this reason, special attention should be paid to the cooperative rearing of young silkworms. (1) Specific requirements and technical measures for cooperative rearing of young silkworms 1. The cooperative rearing room should use a dedicated young silkworm room. It needs good heat preservation and moisture retention performance, and easy ventilation. Strict disinfection should be carried out before rearing silkworms, implementing "three disinfections and one fumigation." "Three disinfections": the first round uses lime slurry; the second round uses bleaching powder; the third round uses disinfection cleaner; "one fumigation": use toxic powder fumigation smoke. 2. Heating is uniformly provided by heated bed warming. Because heated bed warming makes

A Detailed Explanation of Tuna Fishing Methods and Operational Procedures
There are quite a few methods for catching tuna, and the most popular one today is longline fishing. Longline fisheries are divided into three types: surface longline, bottom longline, and midwater longline. Tuna longline fishing gear is mainly composed of a main line, branch lines, floats, float lines, and hooks, that is, a tool for catching tuna by hanging several hooked branch lines from an extended main line. Several floats are tied to the main line, and the float lines between the main line and the floats as well as the length of the branch lines serve to adjust the fishing depth. The hooks need to be baited. The bait mainly includes frozen saury, squid, sardine

Introduction to the Characteristics of the Potato Variety Cooperative 88
"Cooperative 88" was developed by the Tuber Crops Research Institute of Yunnan Normal University and the Huize County Agricultural Technology Center through single-plant selection in Huize in 1990, using 42 cross combinations provided by the International Potato Center. It passed the provincial regional trial in 1994, was approved at an expert appraisal meeting in 1995, and entered the agricultural extension system of Yunnan Province. In 2001, it passed the approval of the Yunnan Provincial Crop Variety Approval Committee and was named Dian Potato No. 4. Characteristics: "Cooperative 88" has an erect plant type, dark green leaves, green-purple stems, and large compound leaves

Correct methods and operation steps for taking a pig's temperature
A pig's body temperature usually refers to the temperature inside the pig's anus and rectum. The specific procedure is to tie a thin string about 10-15 cm long to the far end of a veterinary thermometer, and tie a small iron clip to the other end of the string for fixing. When taking the temperature, first shake the mercury column of the thermometer down below the 35°C mark with a little force, apply a small amount of lubricating oil to the thermometer, then grasp the pig's tail with one hand, hold the thermometer with the other hand and insert it into the anus slightly toward the dorsal side, and use the small iron clip to clamp and fix it to the hair above the base of the tail. After 2-3 minutes, remove the thermometer and use an alcohol cotton ball

Correct Methods and Detailed Operating Steps for Medicating Fish Fry Baths
Medicating fish before stocking is simple and safe, with ideal results in preventing and treating fish diseases. Here are several good methods for medicating fish fry baths. 1. Potassium permanganate bath method: Bathe in a 10-20 mg/kg potassium permanganate aqueous solution for 10-30 minutes, which can kill bacteria, protozoa, monogeneans, etc. on the body surface and gills. Potassium permanganate should be prepared and used fresh; the water used for the solution should be clean water containing relatively little organic matter, and the bath should be carried out away from light. 2. Bleaching powder bath method: 10-20

Detailed Explanation of Primary Processing Methods and Operating Steps for Gastrodia elata
When Gastrodia elata is sold fresh or delivered for sale, after harvest it should be kept from being bumped, knocked about, or mechanically damaged, then the soil and sand on the tubers should be gently brushed off with a soft brush, and they can be packed into soft-lined wooden boxes or plastic crates. If processing dried Gastrodia elata, it takes longer; generally the boiling method and the steamer method are used for cooking, followed by oven drying or sun drying. In actual production, the steamer method and heated kang drying method are generally used for drying, and the operational process flow is: grading Gastrodia elata -> washing with clean water -> steaming until cooked over high heat -> heated kang drying at 50°C for 60 minutes, at 60°C for 60 minutes, at 70°C for 6

Detailed Explanation of Lily Scale Propagation Methods and Operation Steps
There are four lily propagation methods: scales, bulbs, bulbils, and seeds. Propagation by seeds and bulbils flowers late and is prone to variation. Bulb seedling raising flowers early, but the propagation coefficient is low, the amount of planting material used is large, and the cost is high. Therefore, for large-scale seedling raising, scale propagation is mostly used. 1. Seed selection. For lily scale propagation, select excellent varieties, choose fully mature, pest- and disease-free bulbs with plump scales, and peel off the thick, intact outer scales as seed material. 2. Seedbed preparation. For lily scale seedling raising, the seedbed requires
