The importance of flower and fruit management in jujube trees, which growers must not neglect
The jujube tree is a species that produces many flowers, with a very large amount of flower differentiation, but affected by the tree body and environmental conditions, flower drop and fruit drop are very serious, and the harvested fruit rate is generally only 1-2% of the number of flower buds. The causes of flower and fruit drop in jujube trees are many-sided. First, from the phenological phases of jujube, it can be seen that the bud stage of the jujube tree coincides with the rapid growth period of the fruiting branchlets and the vigorous growth period of the jujube heads; in this period the phenological phases overlap and nutrient competition is very intense. When it enters the initial flowering stage, the jujube heads are still in a vigorous growth stage, while at this time the growth of the fruiting branchlets gradually slows. In the same period, several organs of the jujube tree

Strengthen Care for Feverish Pigs: Daily Nursing Cannot Be Neglected
The normal body temperature of pigs is 38-40°C; if it persistently exceeds 40°C, it is considered a fever. Prolonged continuous high fever accelerates the body's catabolism, disrupts digestive function, lowers resistance, and can even cause coma or heart failure. The treatment principles for feverish pigs are as follows: immediately isolate the feverish pig, and thoroughly disinfect the contaminated environment. Before the cause is identified, as long as the fever is not excessively high, generally do not use antipyretic drugs at will. While using antibacterial drugs, attention should be paid to supplementing nutrition.

Color conversion of shiitake mushroom logs is crucial and growers must not neglect it
When the shiitake mycelium has fully colonized the bag and reached a certain physiological maturity, the aeration, light, temperature and humidity of its growing environment are artificially regulated so that all the aerial mycelium on the surface of the substrate lies down and secretes pigments; the color of the substrate surface gradually changes from dense white and pale white to light brown and then to brown and dark brown, finally forming a brown fungal film that combines multiple functions such as insulation, moisture retention, light exclusion and resistance to contaminating microorganisms. This process is called color conversion. The depth of color and the thickness of the fungal film in shiitake log color conversion are closely related to the fruiting time, fruiting yield and mushroom quality. Under general conditions
