Does the orange tree need pruning

A low-key silent person
Selected answers

Orange trees need to be pruned, and the pruning method should be flexible according to the characteristics of each variety and the strength of the tree.

The multi flowered trees should be re cut, combined with thinning and truncation; Trees with few flowers should be cut lightly, and only some dense and weak branches should be thinly cut. Dead branches and seriously diseased and insect pests shall be cut off from the base. The senescent branches should be replaced or thinned. The length of the new branches depends on the strength and position of the branches. In principle, cross branches and overgrown branches shall be cut off from the base, but when the middle and lower parts of the crown are relatively empty, they can be cut short as renewal branches or fill gaps; The dense branches should be properly thinned and pruned, and those that are too long should be pinched.

Top ranking generally refers to the top

Ranking top does not always refer to the top. Ranking top is an idiom in Chinese. It originally meant that when the troops of the ancient Chu State marched, if the outpost met the enemy's situation, they would give a warning. Later, "Ranking top" literally meant ranking first, describing excellent performance. Its own structure is subject predicate, which can be used as predicate, attribute and commendatory in sentences. From the Twelve Years of Zuo Zhuan Xuangong written by Zuo Qiuming in the Spring and Autumn Period: "As the ruler of the State of Chu, he chose the order and code of the State of Chu for military conduct, right shaft, and left pursuit of production. He had no foresight, power, and stamina. All officials moved like objects, and military and political affairs were not disciplined, so he could use the code."
At first sight, the idiom "Top Rank" means that Chu's army is well-trained and orderly. In fact, it reflects that Chu's morality, punishment, politics, affairs, code and etiquette are not against the rules. Such a country and army are invincible.

Is Sun Jing a historical figure

Sun Jing is a historical figure, a famous statesman and strategist of the Han Dynasty, and the hero of the "hanging beam" in the idiom "hanging beam and stabbing shares".
Sun Jing was a native of Xindu (today's Jizhou District, Hengshui City) in the Han Dynasty. He was eager to learn at a young age, learned extensively and memorized well, and regarded books as his life. Reading and studying at night often stay up all night. The neighbors called him "Mr. Closer".
When Sun Jing was reading, he kept taking notes at any time. He often saw it in the second half of the night. As time went by, he sometimes fell asleep. When I woke up, I felt regretful again. One day, when he looked up and pondered, his eyes stopped on the beam of the room, and suddenly his eyes lit up. Then he found a rope, one end of which was tied to the beam, and the lower end was tied to his hair. In this way, whenever he is tired and sleepy and wants to doze off, as long as his head is lowered, the rope will suddenly pull his hair, and a pain will wake him up and drive away the drowsiness. From then on, he used this method to study hard every night. Years of hard work enabled Sun Jing to read poetry and become a knowledgeable scholar. At that time, he was quite famous north of the Yangtze River and Huaihe River, and students from thousands of miles often came to him to learn and discuss knowledge.

Does the temperature rise with the increase of internal energy

When the internal energy of the object increases, the temperature does not necessarily increase. The size of internal energy is related to the mass, volume, temperature of the object and the kind of substances that make up the object. For example, when the crystal melts or the liquid boils, the temperature remains the same, but it needs to absorb heat and the internal energy increases.
In general physical problems (not involving the excited ionization of electrons, chemical reaction and nuclear reaction), only the molecular kinetic energy and potential energy will change in the internal energy. At this time, we only care about these two parts, and define the sum of these two parts as internal energy. This is a simplified definition, namely internal energy in a narrow sense. When it comes to excited ionization of electrons, chemical reaction and nuclear reaction, in order not to cause misunderstanding, internal energy in the narrow sense should be strictly called thermodynamic energy (formerly called heat energy, which is still widely used in some engineering fields).
