How to control boxwood pests? These methods are very practical
The larvae damage host plants such as boxwood, small-leaved boxwood (Buxus sinica), big-leaved boxwood (Buxus megistophylla), little-leaved boxwood, Japanese boxwood (Buxus microphylla), spoon-leaved boxwood, Korean boxwood, and holly by spinning silk to tie leaves together into nests. The damaged leaves first show yellow blighted spots, and later the entire leaf falls off. By spinning silk, they bind the leaves and the damaged fallen leaves together, preventing the leaves from spreading out, so growth and development are severely affected, and in severe cases the whole plant dies. In Shanghai, 3 to 4 generations occur per year, with severe overlapping of generations; they become active in March of the following year, begin pupating in mid-April, and begin emerging in late April

How to Store and Preserve Fresh Peaches? Practical Methods Shared
1. Cold storage. Peaches are prone to chilling injury during low-temperature storage, and there is a risk of freezing at -1°C. Therefore, the suitable storage temperature for peaches is 0°C, and the suitable relative humidity is 90%-95%. Under these storage conditions, peaches can be stored for 3-4 weeks or longer. However, when peaches are stored at low temperature for a long time, the flavor gradually becomes bland, and long-term cold storage can cause chilling injury to the peaches, with the flesh turning brown. In particular, when the peaches are moved to a high-temperature environment for ripening, the flesh becomes dry, mealy, and soft, and the flesh around the pit turns noticeably brown. In cold storage, using

How to control onion flies? A detailed guide to practical control methods
The onion fly, also called the onion maggot, is an oligophagous pest that only harms vegetables of the Liliaceae family, especially onions and garlic. Controlling the onion fly should adopt a method combining agricultural control and chemical control. When garlic bulbs are rotting, a topdressing of ammonia water can be applied along with watering, which can significantly reduce the damage. When root maggots are found in the field, watering should be done frequently, and flood irrigation can be used when necessary. Chemical control should combine aboveground and underground control, with adult flies controlled mainly aboveground. In the early stage of adult occurrence, you can use 80% dichlorvos emulsifiable concentrate at 800 times dilution,

How to store lotus root? Four practical methods shared
1. Sand storage method: Choose a spot with high terrain, sheltered from wind and rain, spread a layer of fine sand on the ground. The fine sand should have a moisture level such that it forms a ball when squeezed by hand and crumbles when released. Dig drainage ditches around the perimeter. Place a layer of lotus root, then a layer of fine sand, alternating sand and lotus root in this way, stacking 5~6 layers, and cover the top with wet sand about 10 cm thick. This method generally allows storage for about 60 days. Alternatively, you can build a burial pit indoors enclosed by bricks or wooden boards, spread a 5 cm thick layer of wet sand in the pit, arrange the dug-up lotus roots with mud in order, then stack layer by layer, one layer of lotus root and one layer of wet sand, stacking 5~6 layers, and on top

How to prevent porcine epidemic diarrhea? A detailed guide to practical prevention and control methods
To prevent porcine epidemic diarrhea, vaccinate in advance with the attenuated porcine epidemic diarrhea vaccine or the inactivated vaccine; to prevent transmissible gastroenteritis, inject 1 ml of the attenuated transmissible gastroenteritis vaccine intramuscularly and intranasally in sows 45 days and 15 days before farrowing; there is no vaccine for rotavirus disease, so once sick pigs are found, isolate them early, inject 5%-10% glucose saline intravenously with 3%-5% sodium bicarbonate added, stop suckling the piglets, and prepare a glucose-glycine solution for the piglets to drink, with the formula: glucose 43.2

How to improve sows' summer anestrus? Practical methods shared
Doing a good job in sow breeding is an important part of developing the pig farming industry and pig farming profits. Generally, multiparous sows 28 to 35 days after farrowing will naturally come into estrus and be mated within 3 to 5 days. But in summer and autumn, pigs are not easy to come into estrus. To enable sows to come into estrus and be mated normally after weaning, the following few measures can be taken. Feed lactating sows well. In summer the temperature is high, sows fear heat, their appetite drops obviously, they cannot meet their nutritional needs, and the sows lose weight with poor body condition, which is the main reason sows do not come into estrus. Therefore, it is necessary to adjust as early as possible

Detailed Explanation of the Characteristics and Practical Applications of Euonymus japonicus
Euonymus japonicus, also known as Japanese spindle, is native to Japan. It prefers a warm, humid environment with plenty of sunlight, has strong cold resistance, tolerates shade, and withstands drought and poor soil. It grows best in fertile, loose sandy loam. Propagation is commonly done by cuttings, and rooting is fastest when cuttings are taken during the plum rain season. Select semi-lignified mature branches, 12-15 cm long, and insert them into a seedbed made of half sand and half soil; they root 20-25 days after insertion. Transplanting of seedlings should not be carried out in spring from March to April. Small seedlings can be planted bare-rooted, while large seedlings need a soil ball. Planting

How to Increase Royal Jelly Production? Analysis of Practical Technical Measures
Increasing royal jelly production is an important guarantee for improving the economic benefits of beekeeping. To increase royal jelly production, the following 5 technical measures should be implemented well. 1. Cultivate strong colonies, bringing the bee colony strength to a full colony of 12 frames or more. Among bees, royal jelly is secreted by young bees and is the main food supplied to the queen bee and bee larvae. Therefore, to increase royal jelly production, there must be strong colonies with more young bees, and the royal jelly production colonies must be adjusted in a timely manner. If there are only 6-7 frames of full bees, it will be impossible to achieve high royal jelly production. For this reason, it is necessary to increase young
