  • 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.

  • Detailed Explanation of Key Technical Points for Environmental Control of Nursery Pigs

    1. Keeping Warm 7-8 kg weaned piglets entering the nursery barn should have their appropriate ambient temperature maintained at 24.5°C; at 20-25 kg, the appropriate ambient temperature is 23.0°C-24.5°C (generally the barn temperature is raised by about 2°C-3°C after weaning). 2. Creating Good Environmental Conditions Nursery pigs are highly susceptible to infection by pathogenic bacteria and becoming ill, so the barn should be kept dry, with a clean and hygienic environment and fresh air. Use wooden boards or electric heating plates as bedding to prevent piglets' abdomens from getting cold and to prevent their feet and knees from being worn sore

  • What is the relationship between diseases of eels raised in earthen ponds and the water environment?

    The water environment is the decisive factor in eel farming. The water environment not only determines whether eels can be farmed, but also directly affects the level of production and ultimately the economic benefits of farming. Therefore, only by improving the water environment can eels be farmed well. The following analysis focuses on the relationship between eel diseases and the water environment from the following aspects. 1. pH level. The pH value in water is an important comprehensive water quality indicator, and it directly affects the physiological condition of eels. When the biological, chemical or physical components in the water body change, they will all be reflected in the pH value. Eels in earthen ponds require the pond water

  • What are the characteristics of the ecological environment in which licorice grows?

    Licorice is widely distributed in the warm temperate and cold temperate continental monsoon climate zones of the arid and semi-arid regions of northern China. The suitable average annual growing temperature is between 3 and 10°C, and the altitude range is 250 to 1400 m. Licorice is an indicator plant of calcareous soils in the dry regions of China. Its requirements for soil are not very strict: it can grow in sandy loam, light loam, heavy loam and clay, and it grows best in sandy-covered loam with a sandy upper layer. Licorice has extremely strong cold resistance and drought tolerance; at an absolute minimum temperature of -47°C it still

  • What kind of growing environment suits licorice?

    The native range of licorice belongs to continental arid and semi-arid desert zones, characterized by drought, low rainfall, strong light and large temperature differences. Growing under these climatic conditions for a long time has given licorice its traits of cold resistance, heat tolerance, drought tolerance, fear of waterlogging and love of light, and it especially favors calcareous soil; it can grow in the arid regions of Northeast China, Northwest China and North China. The seeds exhibit hard-seediness, with a hard seed rate between 70% and 90%; alternating temperatures of -5 to 20°C give good germination, generally above 50%, and the seeds live for 1 to 2 years. Seed

  • How to create the right environmental conditions for growing-finishing pigs (Part 1)

    Intensive pig production is carried out under high-density housed conditions, and the microclimate inside the pig house is the main environmental condition. The microclimate of a pig house includes: temperature, humidity, wind speed, gases, sound, and so on. These environmental factors all directly affect the weight gain rate, feed utilization rate and ultimately the economic benefits of pigs. 1. Suitable temperature and humidity Pigs have a poor ability to regulate their own body temperature; they have only very few sweat glands that can help regulate it in hot weather, and only very little hair coat to resist the cold of winter. Therefore, pig houses must have good heat insulation and warmth retention, and

  • Diagnosis and Treatment of Common Poisonings in Chickens: Feed, Drugs and Environment (Part 1)

    1. Cottonseed cake poisoning. Cottonseed cake contains 36%-42% crude protein and is rich in selenium, phosphorus and B vitamins, making it an economical and effective protein feed. However, cottonseed cake contains toxic substances such as free gossypol and cyclopropene fatty acids. After absorption, free gossypol can accumulate in the body and poison the cells of nerves, blood vessels and organs. Feeding cottonseed cake continuously over a long period will cause poisoning. 1.1 Symptoms. At the beginning of the disease, the flock's appetite decreases, water intake increases, and the chickens are listless

  • What kind of growing environment does oleander like?

    It likes sunny, warm and humid environmental conditions. It is relatively cold-tolerant, slightly shade-tolerant, slightly alkali-tolerant, tolerant of drought and poor soil, and intolerant of waterlogging; it has a certain resistance to toxic gases such as smoke and dust and sulfur dioxide. It is suitable for growing in fertile, loose, well-drained slightly acidic to slightly alkaline soil. Light and temperature: potted oleander needs to be brought indoors to overwinter, with the room temperature kept above 5°C, placed in a spot by a window with full sunlight. Generally it is moved into the greenhouse around October 20 and moved out of the greenhouse around April 20. After being moved out, it should first be placed in a wind-sheltered, sunny spot, then gradually
