Autumn is a great time for softwood cuttings of roses. At present, cuttings are still the main method of propagating roses. It can not only maintain the characteristics of superior rose varieties, but also has a high propagation coefficient, a short production cycle, low input and quick results, and is still adopted by many flower growers. However, in the process of rose cuttings, "false rooting" often occurs due to lack of experience or improper methods. That is to say, 5-10 days after the rose is cut, the axillary buds on the cutting have already sprouted or produced shoots and leaves, and it looks as if it has taken root, but soon it wilts and dies.

The Effects of Different Temperatures on Pigs and Countermeasures
I. Effects of ambient temperature on pigs. 1. Effects on pig health. In a continuously high-temperature environment, the resistance of pigs is significantly reduced, the body heat balance is disrupted, body temperature rises, coma occurs, heat stroke develops, and in severe cases death results. In a low-temperature environment, in order to conserve heat, pigs constrict their peripheral blood vessels, causing local frostbite. Low temperatures cause respiratory diseases and also often lead to rheumatism, arthritis and other diseases. Low temperatures have a greater impact on piglets; according to statistics, half of the dead piglets were frozen to death or died from cold-related diseases.

What effect does light have on the growth and health of pigs
Lighting in pig houses can be divided into natural lighting and artificial lighting according to the light source. Natural lighting refers to direct sunlight and scattered light entering the pig house through light-transmitting structures such as doors and windows for illumination. In the solar spectrum, visible light accounts for 50%, and most of the remaining 50% is infrared light, with a small amount being ultraviolet light. Natural lighting in a pig house is generally expressed as the ratio of the total light-transmitting area of the pig house to the floor area inside the house, which is called the lighting coefficient. Artificial lighting uses artificial light sources (incandescent lamps or fluorescent lamps, etc.) for illumination. In the spectrum of incandescent lamps, infrared accounts for 60%

Strengthen pig drinking water management to effectively improve pig farming benefits
Strengthen pig drinking water management, supply sufficient drinking water according to the physiological characteristics of pigs, and meet the water needs of growth and development, especially for fattening pigs, water management should be strengthened even more. The specific methods are: 1. Set up drinking troughs. In order to meet the drinking water needs of pigs and avoid all the disadvantages caused by insufficient drinking water, pig farmers should give pigs drinking water at least 4 to 5 times a day. It is best to set up dedicated drinking troughs in the pig house or activity yard so that pigs can drink freely and meet the water needs of pig growth and development. 2.

Several Practical Ways to Improve the Effectiveness of Fish Medications
1. Improve the binder. The binder must be strongly adhesive, otherwise the medication is easily lost in the water. Standard wheat flour is a good binder material. For swallowing fish, it is best to make pellet medicated bait or ball-shaped medicated bait. 2. Add a feeding attractant. Fish have a sensitive sense of smell; even if 1 gram of alanine is dissolved in 1000 tons of water, fish can still detect it. For example, grinding the strongly aromatic Chinese herbs star anise and Angelica dahurica into fine powder as a feeding attractant, mixing it into fish medication at a ratio of 10%-20%, or adding
