How to care for a cow with a fever? These four measures you need to master
Drink more water After a sick cow develops a fever, its body consumes a lot of nutrients, its mouth is dry, and its appetite decreases, leading to anorexia. Therefore, the water supply should be met, otherwise the condition will worsen. It should drink more water to replenish body fluids and promote the excretion of intestinal toxins; adding an appropriate amount of sugar and salt to the drinking water is even better. Rest more The cowshed should be kept clean, hygienic and quiet, and the sick cow should be allowed to rest more to reduce the sick cow's muscle activity, thereby lowering physical consumption and heat production. Do not disturb the sick cow while it is sleeping; better deep sleep can significantly enhance the cow's immunity and improve resistance

What are the three key factors for turtle egg incubation? Master the key points to improve the hatch rate
The key to turtle breeding is doing a good job of turtle egg incubation. No matter which incubation method is used, the three key factors of incubation temperature, humidity and ventilation must be well controlled. According to our farm's incubation experiments in recent years on the eggs of different turtle species such as the three-striped box turtle, alligator snapping turtle, yellow pond turtle and hawk turtle, as long as temperature, humidity and ventilation reach the optimal state, the hatch rate of turtle eggs can reach 93%-98%. 1. Incubation temperature The suitable temperature for turtle egg incubation should be controlled at 28°C-35°C, with about 30°C being best. It must not be too high or too

How is upland rice cultivated? These technical points need to be mastered
Upland rice cultivation should master the following points: (1) Select a suitable sowing period according to variety characteristics. Generally the same as the local early and middle rice. (2) Choose plots with deep soil plough layers and good water retention. Mountainous land with steep slopes, shallow plough layers and high coarse sand content is not suitable for planting upland rice. (3) Deep ploughing and fine preparation, with sufficient base fertilizer. Plough layer over 15cm, bed width about 1 m. Apply base fertilizer per mu by banding or hole application: phosphate fertilizer 50 kg, potassium fertilizer 10 kg, farmyard manure 500 kg. (4) Direct seeding or seedling raising and transplanting. Direct seeding can be drilled

Repotting rhododendrons after flowering has its particularities; only by mastering the method can they survive well
When choosing a pot, select a suitable pot according to the size of the plant, with clay pots being best; generally the pot diameter (inner diameter) should not exceed half the crown diameter. Rhododendrons prefer acidic soil, requiring a pH of 4.25-5.5; without maintaining this acidity, potted rhododendrons are very difficult to keep alive, and the potting soil must be loose, well-draining and rich in humus; never use heavy clay soil. When using soil, it is best to prepare it according to the original root-ball soil of the rhododendron; plants previously grown in pine-needle soil should still use pine-needle soil, which can be mixed with a small amount of decomposed horse manure and bone meal, and

How to prevent and treat root rot in rhododendrons? These methods you need to master
Root rot is a serious threat to rhododendrons. Although its incidence rate is not high, the mortality rate after infection is very high, so the prevention and treatment of root rot must be taken seriously in the cultivation and management of rhododendrons. Root rot is a soil-borne disease caused by Fusarium fungi, mostly occurring at the root and stem parts of rhododendrons, because these parts are often moist with insufficient sunlight, and the Deuteromycetes Fusarium fungi are highly active there. Once they invade the cortex, rot soon follows, with water-soaked brown spots and soft rot appearing on the roots, followed by decay and peeling of the bark, the xylem turning dark brown

Detailed explanation of Chinese honeylocust seedling cultivation techniques, master the key propagation points
Chinese honeylocust (Gleditsia sinensis), also called "zaojiao", is a deciduous tree of the Fabaceae family, reaching up to 30 m tall. Its wood is solid and is used for making furniture, vehicles, farm tools, etc.; the pods are rich in saponin, and using them to wash silk and valuable furniture does not damage the luster; in traditional Chinese medicine, the pods, thorns, seeds and deformed pods are used as medicine. The pods are warm in nature, pungent in taste, and slightly toxic; their functions are to dispel phlegm and open the orifices, and they are mainly used to treat profuse phlegm with cough and asthma, lockjaw from stroke, epilepsy and other conditions; the thorns of Chinese honeylocust are called "zaojiao thorns", with the function of expelling toxin and draining pus, mainly used to treat carbuncles, swellings and sores, and for conditions where pus has already formed but has not yet ruptured

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

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. Control methods: ① Avoid planting next to leguminous plants. ② During the occurrence period, spray with 40% dimethoate emulsifiable concentrate at 1000 times dilution.

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 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
