Emergency treatment for cattle bloating, farmers must master it in time
Causes of bloating There are three main causes of bloating in cattle: 1. Eating green plants containing too much water and soluble protein. 2. Overeating grain feed and forage, which accelerates the decomposition of fatty acids, lowers the alkalinity in the rumen, and leads to acid accumulation. 3. Mechanical obstruction of the esophagus, which hinders belching. Bloating in farm cattle is generally not difficult to diagnose; the difficulty lies in how sudden the onset is, and often there is no time to find a veterinarian for diagnosis and treatment before death occurs in 1 to 2 hours.

How to control cotton mirid bugs? These methods must be mastered
The occurrence of mirid bugs is very sensitive to the ecological environment. Mirid bugs prefer temperatures of 25°C~30°C and a relative humidity of 80%~90%. The recent humid weather with little sunshine is very favorable for the occurrence of mirid bugs. Intercropping in cotton fields is also conducive to the parasitism and transfer damage of mirid bugs. Now, soybeans, broad beans and other vegetables are intercropped in cotton fields everywhere, which is conducive to their reproduction. Therefore, some cotton farmers in cotton areas of counties and cities such as Hanchuan and Yunmeng in Hubei Province have recently reported that the occurrence and damage of mirid bugs have already emerged

How to carry out field management of licorice? Four key points to master
Cultivation: Licorice seedlings grow slowly, and weeds have a relatively large impact on them. Cultivation should be combined with timely removal of weeds, with weeding 2-3 times in the same year. After the plants grow larger, weeds become fewer. Pay attention to pulling out weeds, and avoid hoeing the soil, so as not to damage new shoots sprouting from the rhizome. Topdressing: Licorice belongs to the legume family, and its root nodules have nitrogen-fixing ability, so nitrogen fertilizer is generally not applied, and phosphate fertilizer is mainly used for topdressing. After the aboveground parts of licorice wither in late autumn, 2000 kg of decomposed farmyard manure can be applied per mu to cover the ground, so as to increase ground temperature and soil fertility. Thinning: For direct-seeded seedlings of the same year, when they have 2-3 true

How to control licorice aphids? Master these methods
They damage tender leaves, tender shoots, flowers and fruits. Adults and nymphs suck plant sap; in severe cases they can cause leaves to turn yellow and drop, affecting seed set and marketable yield.

How to control black locust aphids? Master these methods for good results
Control methods for black locust aphids: 1. Protect natural enemies such as ladybugs, hoverflies, green lacewings and aphid parasitoid wasps. 2. Strengthen pest monitoring and forecasting. When the number of winged aphids suddenly increases and the rate of aphid-infested plants reaches 20% to 30%, spray pesticide promptly. If the ratio of ladybugs to aphids reaches 1 to 100, and the aphid population shows a declining trend, stop spraying pesticide for control and protect natural enemies. 3. During the peak outbreak period, spray 50% pirimicarb wettable powder at 1500 times dilution, 10% imidacloprid wettable powder at 1500 times dilution, or spray EB-82 aphid-killing fungus at 300 times dilution
