Pest control:

Fewer diseases and insect pests. When the air humidity is too high in the rainy season, you can spray carbendazim or trimethoprim once to prevent powdery mildew. When used as ground cover or flower border, because of high density, closed plants and poor ventilation, whitefly damage is easy to occur. 1000 times of imidacloprid wettable powder or 1500 times of imidacloprid wettable powder, sprayed once every 5-7 days, twice in a row, can be controlled.

Watch:

Before and after the Dragon Boat Festival, the bulb grows with a thumb, and the root picking bushes are planted in a small basin, which is very interesting on the balcony. In particular, it is tied with a thread, exposed and suspended indoors, and it grows into a U shape, decorating the interior, which is very chic. The scale epidermis contains wax, which protects water from evaporation. In the drought and water shortage season, the water stored by the scales provides for the normal growth of stems and leaves until the water supply is exhausted, and the sphere wilts to complete its growth cycle.

Plant culture:

Most of the traditional Chinese culture is the symbol of living in a high position. Tang Dynasty poet Li Ye "Shangshu Capital Tang Wasong" Yong Wasong: "the secret fairy of Hua Province, Gaotang Luwasong." The leaves grow after spring, and the flowers are thickened by rain. The shadow is mixed in color, and the light contains the appearance of jade. Sent by nature, the terrain is too helpless. The adjacent building faces Shuangque, and Lianhe is nearly nine heavy. I would rather know the bottom of the deep stream, and the frost and snow will be sealed at the same time. Sustenance oneself wants to rely on the authority to reside on the high place temple hall idea. On the other hand, Zheng Gu "Ju" said, "Wang Sun Mo compares the Artemisia annua, the ninth branch is near the temples." Dew wet autumn fragrance all over the pond bank, therefore do not envy Wasonggao "expressed disdain for Wasong." Some ancients believed that although Wasong could blossom and spit leaves, it was "too high to reach a foot, but only an inch below", which is of no practical use, so "Tong Jun (doctor) is not appreciated, but catalpa craftsman (carpenter) is difficult to Zhen." Zheng Gu compares the chrysanthemums on the bank of the pond with the Wasong on the high house, in order to show that although the chrysanthemum grows in the low-lying land of the swamp, it is noble and quiet, and does not hesitate to dedicate its fragrance to the people; although Wasong occupies a high position, in fact, it is "useless in people, but useless in things." Here, the useless Wasong contrasts the elegance of chrysanthemums without seeking power, fame and wealth, which is actually a lack of understanding of the value of Wasong and a writing technique used by ancient people to praise and suppress one by one. it is also a reflection of the narrow thinking of the traditional literati who lack leniency and tolerance.

In the hearts of ordinary Chinese people, there is a kind of ordinary and great grass, which places on the humanistic spirit that the Chinese people are willing to be ordinary, tenacious, persistent and unique. Chen Cun, a modern folk poet, made the first "Seven Wasong": "Why is it difficult for tile seams to stand up?" The jade body dares to be proud of frost cold. Do not sigh to be defeated by Qing Songwei, the style has never been the same, "and chanted:" Qiong Zhi muddy like not through the wind, red courage why not save the poor. The double baptism of the sharp axe and scorching sun and the recommendation of a panacea to Shennong all show that there is a great spiritual charm in Wassong's mediocrity.
