Key management points for cold-frame peaches in the Beijing-Tianjin region around the Spring Festival
1. Frame-covering period. Because cold-frame peaches have no cold-protection facilities and rely solely on sunlight for warming and the frame film for insulation, the day-night temperature difference is large. The frame-covering period should preferably be around February 20, so that the flowering period is March 25-31 and the peach ripening period is early June, 10-15 days earlier than open-field peaches. For heated cold-frame peach sheds, install 1 heater per 350-450 sq m at the center of the cold frame, burning wood or coal; the gas is discharged outside the frame through the chimney in the middle of the stove, and the air is preheated through the stove's interlayer and then

New Shiitake Mushroom Ground Cultivation Technology Helps Cultivation in High-Altitude Cold Mountain Areas
Shiitake mushroom is a temperature-variable fruiting fungus; when the day-night temperature difference exceeds 10°C, it grows well, yields high, produces large and thick-fleshed mushrooms of good quality. In high-altitude cold regions, the day-night temperature difference in spring and summer is large, often exceeding 10°C, making it suitable for cultivating shiitake mushrooms, with a per-mu yield of 3000-4000 kg. The ground cultivation technology for shiitake mushrooms in high-altitude cold mountain areas is a new cultivation model following ground cultivation and bag cultivation of shiitake mushrooms, and it is also a good project for mountain people to escape poverty and become prosperous. The main cultivation techniques are introduced as follows: Cultivation season and temperature. The general sowing period is from April 20 to May 10 each year

Rearing Methods and Technical Key Points for Ground Beetles (Eupolyphaga)
(1) Rearing equipment can be designed according to the scale and purpose of rearing. Here we only introduce the rearing equipment used to provide a source of medicinal insects. ① Insect sieves: their purpose is to separate nymphs of different instars, adults and oothecae by sieving within a certain period, and then rear them separately and isolate the medicinal insect bodies. The sieve apertures are divided into 5 specifications: 2-mesh sieve: used when separating out adults. 4-mesh sieve: used when separating out 7th-8th instar nymphs. 6-mesh sieve: used when separating out oothecae and insect feces. 12-mesh sieve: used when separating out 1st-2nd instar nymphs. 17-mesh sieve

Detailed explanation of year-round production technology for multiple mushroom species in one greenhouse
In 2001, our county began large-scale promotion of white beech mushroom (Pleurotus nebrodensis) production technology throughout the county. The white beech mushroom belongs to the medium-low temperature type of edible fungi, fruiting within the range of 5-20°C. Before fruiting, the white beech mushroom must undergo a low-temperature stimulation process, which determines that the fruiting period in our county is from late November to late March of the following year, causing the mushroom greenhouse to sit idle from April to November around summer, and the biological conversion rate of the white beech mushroom is also relatively low. Starting from 2002, our county began trial

Haemanthus albiflos stays green through all four seasons and is full of vitality all year round
Haemanthus albiflos (white paintbrush lily) is a perennial evergreen herbaceous plant of the genus Haemanthus in the Amaryllidaceae family, native to southern Africa. The broad-leaved plants grow 20-30 cm tall, with a shortened or flattened-globose rhizome that is jointed. The leaves emerge from the base, are opposite, spreading and broad, usually 4-6 in number and neatly arranged. Haemanthus albiflos likes a sunny, warm, humid and well-ventilated environment. It is fairly drought-tolerant but not cold-tolerant, with an optimum growing temperature of 15-25°C, and requires well-drained, slightly acidic loam. The growing medium for cultivating Haemanthus albiflos can be made by mixing peat, leaf mold and river sand evenly. During the growing season

How to prevent excessive growth in round eggplant? Comprehensive measures are key
Currently, because greenhouses begin closing up at night to retain heat, nighttime temperatures often become too high, causing severe excessive growth of round eggplant in greenhouses. To prevent round eggplant from growing too vigorously and failing to set fruit, the reporter found that vegetable growers commonly adopt the method of controlling water. But in production, relying solely on water control makes it hard to achieve the desired effect, and excessive water control has many drawbacks, such as poor flower bud differentiation and many deformed fruits. The author believes that there are many factors causing vigorous plant growth, so controlling vigorous growth should also adopt comprehensive measures rather than blindly over-controlling water. Temperature controls the plant. The suitable temperature for round eggplant growth is 25 during the day

New technique for semi-underground arched shed cultivation of reishi mushroom
The method of cultivating reishi mushroom by stacking fungus bags into walls and covering with soil in a semi-underground arched shed has many advantages. First, a semi-underground shed costs less to build than a ground-level shed, saving 40% on shed construction costs; second, water management is convenient, as it is only necessary to keep the casing soil layer adequately moist; third, mushrooms emerge from one end, concentrating nutrients, so the reishi mushrooms grown are robust and of good quality; fourth, a semi-underground arched shed is warm in winter and cool in summer. When the outdoor ground temperature is around 40°C in summer, the temperature inside the shed does not exceed 36°C, and in winter it is 3°C--4°C higher than ground level. The skylights on the shed roof can meet the light requirements and provide ventilation. The technique is briefly described as

How to achieve year-round production of anise? Detailed explanation of key technical points
Anise is an annual herbaceous plant of the Apiaceae family, genus Pimpinella. It originated in Eurasia, with Greece and Egypt being particularly abundant. The seeds can be used as a food seasoning and for medicinal purposes; the seedlings can be used as a green vegetable or salad garnish. 1 Botanical characteristics: The plant is 35-40 cm tall, with a slender form, and the whole plant has a very fresh and delicate fragrance, with a spindle-shaped taproot. The stem is relatively thick and cylindrical, with shallow grooves, and the upper part of the stem is much branched. The lower stem leaves are nearly round to kidney-shaped, with blunt notches and long petioles; the upper stem leaves are fully divided, almost

What treatment works well for chickens that crane their heads back to look at the sky and kneel on the ground?
In the process of raising chickens, you will often come across some chickens with strange, bizarre postures: the first is the head tilted backward, with both eyes looking up at the sky. The second is walking while kneeling on the ground. What disease are these two postures in chickens a sign of, and what methods are used to treat them? The first strange posture: head tilted backward, both eyes looking up at the sky. It is a sign that the chicken has VB1 deficiency. VB1, also known as thiamine, is a substance essential for carbohydrate metabolism in the chicken's body. Nervous tissue relies on the oxidation of carbohydrates to supply energy; if VB1 is deficient, then because of insufficient energy supply to its nervous tissue, nutritional disorders of the nerves will appear, leading to functional imbalance, and the sick chicken will show multiple neuritis. VB1 deficiency also slows the chicken's intestinal peristalsis, relaxes the intestinal wall, reduces appetite, and stunts growth. VB1 deficiency can occur in chickens of all ages, but chicks and young chickens are affected more often. Sick chickens have weakness in both legs and an unsteady gait; because of inflammation of the peripheral nerves, the head bends extremely backward, in a shape that looks like gazing at the sky. Prevention and treatment: First, supply enough VB1 in the chicken's diet; adding 0.8 to 0.9 mg per kilogram of feed for young chickens and adult chickens, and 1.5 mg per kilogram of feed for chicks, can prevent the occurrence of this disease; second, for chickens already affected, intramuscular injection of 5 mg of thiamine (the amount for one chicken), once a day, for five to seven consecutive days, gives an extremely good therapeutic effect.
