Golden coin turtle: When selecting, hold it in your hand and turn it over; its head will extend very long, with even thickness, and its eyes will move flexibly and look lively. The skin should be glossy, the temperament gentle, the gap between the upper and lower shells at the tail large, and the cloacal opening wide. Turtles aged 6 years or older are required.

How to best select Gastrodia elata tubers for use as seed
Gastrodia elata tubers that are undamaged, free of pests and diseases, and free of deformities are best for cultivation as seed. However, when seed is in short supply, tubers with minor damage can also be treated and used for cultivation as seed. The treatment method is: first cut away the damaged part with a knife or bamboo slice, sun-dry the cut surface until it no longer bleeds sap, then plant, and generally they will grow as normal. When large white Gastrodia tubers are cultivated as seed, after 1 year they can become 1 large arrow Gastrodia tuber. When arrow Gastrodia tubers are cultivated as seed for asexual propagation, the mixed bud at the tip of the arrow tuber that looks like a "parrot's beak" must be pinched off, so that the arrow tuber will not produce an arrow (no longer send up a stem), which is called "extinguishing the arrow."

How to select and store sweet potato seed tubers? These methods you need to master
1. Timely harvest: If sweet potatoes are harvested too early, the yield is lower; if harvested too late, they are prone to frost damage, which affects storage. Therefore, it is generally best to begin harvesting when the temperature is around 18°C, and finish harvesting when the temperature is above 10°C (that is, before the frost-kill period). 2. Carefully select tubers: When harvesting and selecting good sweet potato varieties, you must dig and cut carefully to avoid wounds. In order to produce more sprouts, strong sprouts and lower costs, tubers weighing 150-200 g should be selected as seed. The selected tubers must be disease-free, free from flood damage, and also have the typical characteristics of the variety. At harvest,

Growing Environment and Variety Selection for Mini Sweet Potatoes
1. Environment selection: Select the planting site according to the environmental conditions standard for pollution-free food - vegetable production areas. At the same time, the soil is required to be loose newly opened red or yellow soil or sandy paddy-upland rotation land, with acidic soil. 2. Variety selection 2.1 Jinyu (formerly Zhe 1257). Bred by the Zhejiang Academy of Agricultural Sciences, skin color pink, flesh color pure yellow, tuberous roots short and round, smooth skin, taste mealy, sweet, and glutinous, fine texture, no coarse fiber (strings), rich aroma, drying rate 30%-32%, 5-7 tuberous roots per plant, uniform tuberous root size, good early maturity, can be harvested in about 110 d (days), suitable for planting in different seasons, marketable tuberous root rate can reach 85%, small tubers below 50 g also have distinctive features and are suitable for hotel and restaurant consumption. This variety emerges well, drought tolerance is average, the main disadvantage is susceptibility to vine cutting disease, effective disease avoidance measures are selecting disease-free seed tubers, high vine cutting, and avoiding continuous cropping, paddy-upland rotation has a better control effect. 2.2 Liangyuan (formerly ais). Introduced variety from abroad. Skin color golden yellow, flesh color red, tuberous roots round, skin relatively smooth, taste soft, sweet, and glutinous, excellent quality, rich aroma; drying rate 25%-26%, suitable for steaming or roasting, 5-6 tuberous roots per plant, uniform tuberous root size. Good emergence, medium maturity, growth period about 130 d (days). 2.3 Xinxiang. A new variety bred by the Zhejiang Academy of Agricultural Sciences. Purple-red skin and yellow flesh, tuberous roots oval, skin relatively smooth, taste relatively mealy, fine texture, relatively sweet, drying rate 27%-29%. Underground tuberous roots are shallow and concentrated, suitable for mechanized harvesting, 6-7 tuberous roots per plant, uniform tuberous root size. This variety has good early maturity and high yield, when cultivated with plastic film mulching from late April to early May, it can be harvested in 90 d (days), yield and maturity are comparable to the high-yielding variety Sushu No. 8, and it can be planted for two seasons a year in Zhejiang Province. 2.4 Zheshu 6025. Purple-red skin and orange-red flesh, tuberous roots oval, skin relatively smooth, when just harvested, taste mealy, after storage (November), starch continuously degrades; taste relatively soft, glutinous, and sweet, good flavor, better to supply the market starting in November, a small amount of coarse fiber at both ends, drying rate 28%-32%. 5-7 tuberous roots per plant, good emergence, aboveground part semi-erect, vigorous growth, dark green leaf color, medium vine, medium maturity, growth period more than 120 d (days), better planted in early to mid-June. 2.5 Zheshu 78. Red skin and orange-red flesh, tuberous roots round, skin relatively smooth, taste soft, sweet, and glutinous, a small amount of coarse fiber at both ends, relatively good flavor, drying rate 25%-26%, good early maturity, suitable for early planting and early harvest, quality declines if harvested after October.

How Do You Identify an Excellent Racing Pigeon? Master These Selection Techniques
Selecting excellent racing pigeons is like picking athletes. Internationally, there are two major categories of pigeon racing: one is the "evaluation show," and the other is the speed race, that is, the performance race, which is further divided into short and medium distance, and long distance and ultra-long distance. An excellent racing pigeon must be moderate in size. Balance and coordination are the most critical conditions shown by the appearance of an excellent racing pigeon, and length and weight are closely related to the balance and coordination of the whole body. Among champion pigeons, there may be racing pigeons that are too large or too small in body type, but most champion pigeons are moderate in size.

Key Technical Points for Site Selection and Land Preparation in Honeysuckle Cultivation
(1) For the seedling nursery, it is advisable to choose sandy loam soil close to a water source, convenient for irrigation, loose and fertile, and well-drained. After selecting the site, plow the soil deeper than 30 cm, harrow it fine and level it, and apply 1500-2000 kg of decomposed barnyard manure or compost per 667 sq m as base fertilizer. Then shallow plow and harrow once, and form beds 100-200 cm wide and 20 cm high. Use these as seedbeds for cutting propagation and sowing propagation. (2) For the planting site, use wasteland slopes, field edges, ditch edges, and in front of and behind houses

Detailed Explanation of Key Technical Points for Weaning and Initial Breeding Selection of Foxes, Raccoon Dogs and Minks
1 Key Points of Weaning Before weaning the cubs, first check the cages and boxes to be used once, repair any damage, and then disinfect them all for later use. Then clean and disinfect the required food trays and water boxes, to be used after the cubs are weaned. Fox cubs are generally weaned at 35-60 days of age, raccoon dog cubs generally at 45-60 days of age, and mink cubs generally at 40-45 days of age. Cubs must not be weaned too early; weaning too early weakens their independent living ability, affects their growth and development, and easily causes disease or even death;
