How Beekeepers Observe Bees Outside the Hive to Judge Conditions Inside
Honeybees are social insects that prefer a stable, quiet environment. In artificial beekeeping, opening the hive to inspect the bees is unavoidable due to production needs. But if the hive is opened too often and too frequently, it will inevitably disturb the colony's stability, and may even cause the colony to refuse the "climate" and abscond as a whole. Under normal temperature conditions, several bees stand at the hive entrance, not biting the entrance, not vibrating their wings, not crawling over one another, only paying a little "attention" to bees going in and out, or slightly following them; worker bees enter and exit one after another in succession; returning bees are either big-bellied, or have pollen pellets stuck to two legs.

The layout of a goose farm requires careful consideration; only scientific planning allows for successful goose rearing
1. Site selection. The site should be close to a water source, with the water surface as wide as possible, a water depth of 1-2 m, and good water quality, and a bit far from residential areas; the soil is best if it is sandy loam, with convenient transportation and a south-facing orientation. 2. Scale determination. The production scale is determined by investment capacity, rearing conditions, technical strength, sources of goslings, and product @#@136@#@, etc. Only by achieving batch production can greater rearing benefits be obtained. 3. Overall planning. First, the buildings should be divided into a production area and an administrative area and living area, with the two areas separated by more than 50 m and separated by a wall.

Cotton expansion requires careful consideration, and farmers should make decisions cautiously
1. Cotton fields are growing steadily, and blind expansion is not advisable. In recent years, China's cotton field area has fluctuated greatly, farmers have suffered many losses, and the lessons are very profound. First, price fluctuations are large due to the influence of the international cotton market; second, domestic cotton prices are unstable, making it difficult for farmers to judge; third, the forecasting standards for cotton production area and output are very inconsistent, the reliability of information is poor, and it is difficult for farmers to determine how much cotton is best to plant. In view of past lessons, this year's cotton field area should only see restorative growth, with an increase of 10% being appropriate, and no more than 15% at most. Of course, each region should adapt to local conditions.

What is the box tree pyralid, an insect found beside vegetable fields?
As spring warms and flowers bloom, insects begin to become active. During a recent science-and-technology outreach activity in the countryside, it was found that a pest called the box tree pyralid had begun to occur and cause damage on boxwood along the roadsides of the park. The box tree pyralid is one of the common pests on plants such as boxwood, small-leaved box, large-leaved box, littleleaf box, Chinese box, spoonleaf box, Korean box, and holly, and it occurs in Shanghai and other provinces and cities. In Shanghai it has 3 to 4 generations per year, with severe overlapping of generations. It usually becomes active in March in spring, begins pupating in mid-April, begins emerging in late April, and the first-generation lar

How to control pests on the underside of azalea leaves?
(1) Red spider mite. The individual is extremely small, with a body length generally around 0.3 mm, difficult to see with the naked eye, and observation requires the aid of a magnifying glass. The body is red, and it often gathers on the underside of leaves, mainly sucking the plant's sap and causing grayish-white spots on the leaves. In severe cases, it causes the leaves to turn yellow and drop, new shoots grow poorly, and the tree vigor weakens. Red spider mites produce 10 generations a year, and the damage is especially severe during high temperature and drought from June to August, but the damage is lighter during heavy rain and rainy weather. In winter, dead branches and fallen leaves should be cleared away to eliminate overwintering adults

How can dog management among urban and rural residents be strengthened? These suggestions can serve as a reference
1 Strengthen leadership and raise awareness. Business departments of governments at all levels should vigorously publicize the harm of rabies to people's health and the medical knowledge for preventing and controlling rabies. Mobilize the whole population to jointly control and eliminate rabies. 2 Formulate unified regulations for the prevention and control of rabies as soon as possible. As an animal, dogs should be managed by animal epidemic prevention supervision departments in accordance with the provisions of the Animal Epidemic Prevention Law, and implementation measures should be formulated as soon as possible, the law enforcement body should be clarified, other departments should actively cooperate, and the management of rabies should be brought

What to do when mushrooms grow from the sides of the bag and many are deformed
During sterilization, the bags press against one another, the round bags become deformed, and gaps form between the substrate and the bag, providing air and space for the mycelium to knot together. Add low temperature, light stimulation and mechanical stimulation (such as turning the bags over), and the mycelium on the sides of the bag knots to form primordia, which develop into fruiting bodies. Because of the restriction of the plastic bag, these mushrooms are all deformed. When this happens, pinch and press the mushroom buds promptly to stop their growth, so as to avoid wasting more nutrients. The fruiting bodies are small and the marketable rate is low:

Greenhouse jujube cultivation beautifies the countryside and enriches jujube growers
Greenhouse cultivation of jujube trees can advance the ripening period of fresh jujubes by 40 to 60 days, and with planting in the same year, fruit is produced in the same year, with a yield of over 600 kg of jujubes per mu. By the second year, it can reach over 1500 kg. The jujube tree itself has the characteristic of producing fruit in the same year it is planted. Planting seedlings in a greenhouse raises the soil temperature, allowing roots to heal early, grow quickly, and sprout early. In addition, the suitable temperature and humidity in the greenhouse during the flowering period significantly increase the fruit-setting rate; whereas open-field jujube trees encounter dry weather during the flowering period, resulting in very few first-crop fruits setting, so the fruit weight and yield of greenhouse jujubes are significantly higher than those of open-field jujubes.
