Method for Propagating Monstera deliciosa by Cutting the Top to Force Buds
Choose a larger Monstera deliciosa that is more than 3 years old, with stem nodes and 10 layers of leaves. Cut off the tender top together with one leaf; the tender top can also be used for cuttings. If it is in its vigorous growth period, it will quickly sprout new tops from the buds in the top two leaf axils of the stem, and generally at least two new buds can emerge each time. At this point, the aerial roots of the new buds will also grow at the same time. When the new buds grow to more than 3 leaves, the long aerial roots will naturally penetrate into the potting soil, and then fibrous roots capable of absorbing nutrients will grow. The two new seedlings are thus naturally formed, except that they are still connected to the mother plant.

Detailed Explanation of Key Points in Artificial Forced Molting Technology for Chickens
1. Chemical method: After chickens ingest an excessive or insufficient amount of chemical substances within a certain period, their metabolism is disturbed and the functions of internal organs are disordered, resulting in the hens stopping laying or molting. After the chemical agent is removed, the hens rest and their physique recovers, and under the condition of being fed normal feed, they again recover a second laying period. At present, the most commonly used chemical method is feeding a high-zinc diet. For example, when feed containing 2% zinc is fed in the diet, after 3 days the laying rate of the chickens drops below 50%, and after 6 to 7 days laying stops completely; after removing zinc,

What to do when large silkworms are forced to mature prematurely by high temperatures? Do a good job of heat prevention and cooling
(1) In hot weather, prevent mulberry leaves from wilting and overheating. When feeding the silkworms, wait until the mulberry leaves have cooled before feeding. When feeding at noon, provide appropriate supplementary water to help cool things down and delay mulberry leaf wilting. This can be combined with supplementary feeding of miecanying or xiaoteling for disinfection. The standard for supplementary feeding of miecanying is 1 milliliter of miecanying agent added to 0.5 kg of water, fed with 4-5 kg of mulberry leaves, mixed evenly and then fed to the silkworms, with supplementary feeding once every 48 hours. The standard for preparing the xiaoteling agent water solution for disease prevention is to add 25 kg of water to each packet of the main agent. First use a small amount of water to

Analysis and Discussion of the Effects of Forced Molting in Chickens
(1) Mortality rate during forced molting. Measures in a forced molting program such as fasting, water withdrawal and reduced lighting are a great stress to chickens, and flock mortality is a response that tests whether the amount of stress is appropriate. Generally, it is suitable to keep mortality during the implementation period of forced molting at no more than 3%, and by the end of the recovery period, to keep mortality within 5%. (2) Body weight loss rate. The decline in hen body weight indirectly reflects the state of fat consumption in the oviduct. Only when the body weight loss rate reaches 25%-30% can the fat deposited in the oviduct be basically exhausted, which is crucial for improving eggshell quality in the second laying period.

Force-feeding methods and technical key points for meat-type squab
Meat-type squab at 18 to 25 days of age can reach a body weight of 350 to 500 g, and depending on the situation can be considered ready for market. However, at this time the squab meat has a relatively high water content and little subcutaneous fat. To improve the quality of the pigeon meat, force-fattening can be carried out for 5 to 7 days before sale. After force-fattening, the squab is crisp-skinned, tender-boned and flavorful after cooking. 1 Squab selection: Squab from 10 to 25 days of age can all be force-fattened. Most often, squab at 15 to 20 days of age with a body weight of 350 to 500 g are used for fattening

Guizhou and Shanghai Join Forces to Farm the Chinese Zebra Loach Artificially, Saving Guizhou's Native Fish
Jinqian Online News: A reporter learned yesterday from the Luodian Fisheries Station that at present, the fisheries departments of Guizhou and Shanghai are jointly conducting experimental research and development on the artificial domestication and breeding of the Chinese zebra loach (Botia zebra), in order to save this rare native aquatic wildlife species of Guizhou in the Pearl River system - the Chinese zebra loach. The "sesame sword" (scientific name: Chinese zebra loach) has no scales and a body shaped like a sharp sword; it gets its name from the sesame-like spots on its body, lives on the bottom of rivers, and feeds on small aquatic animals. It is mainly distributed in the Pearl River and Yuanjiang River systems, and its flesh is tender and delicious, making it an important commercial fish in its producing areas. Together with the sea bass (Japanese sea perch)
