I recommend a few novels. " Cultivation: From the Way of Thought to Experience " was a fantasy novel written by the Spring and Autumn Annals. The main character had transmigrated to a different world of demons and devils. There, the Divine Dao, Immortal Dao, Martial Dao, and demons were all different. The main character, Xu Yan, was in the Marquis Dingyuan Mansion. He relied on the proficiency panel to start his journey of Dao from the Way of Thought. It was very exciting. " Love Chun Love " was Chun Jing's romantic youth novel. The male and female lead Fang Zichun and Lan Keer met in the 1990s and missed each other. Later, their fates were similar and they reunited because of music. There were many difficulties in the middle. There were many characters in the book, and their characteristics were distinct. For example, Lan Keer was gentle and beautiful, while the male lead Fang Zichun was arrogant and confident. Different characters had different charms. " Since I've fallen in love with you, I won't let go." Who else can I love other than you? It was a young school novel. The relationship between the male and female protagonists was very interesting.

The bleached-layer soil is a layer of soil formed by the loss of clay particles and/or free iron dioxide, sometimes accompanied by the in-place condensation of iron dioxide. Its color was mainly determined by the sand particles and powder particles that formed the whiteness. The bleached layer was usually composed of bleached substances, including segregated iron-Mn agglomerations, agglomerations, and patches. The whiteness itself showed the characteristics of the color, such as a tint lower than 2, a moistened lightness greater than 3, a dry lightness greater than 6, and so on. The thickness of the blanched layer was generally between 20-30cm. Its distribution and formation in the soil are related to the clay content, iron dioxide content, water eluviation and drainage of the soil. There was a specific level of diagnosis for the bleached layer in the soil systematic classification. For example, there was a classification for the bleached layer in both the Chinese soil systematic classification and the American soil systematic classification. However, there were still some disputes and differing views on the cause and nature of the bleachers.

There are many types of soil pesticide to choose from. The following are some commonly used soil pesticide: 1. Imidacloprid: It has the characteristics of systematic absorption, high efficiency, wide spectrum of insects, long duration, etc. It is suitable for controlling piercing-sucking mouthpart pests, such as aphids, leafhoppers, planthoppers, whiteflies, thrips, etc. 2. Acetamiprid: It has the characteristics of strong internal absorption, low dosage, good quick-acting, high activity, long duration, etc. It is suitable for controlling pests of vegetables, fruit trees, potatoes, tobacco and other crops. 3. Thioxam: It has the characteristics of contact toxicity, stomach toxicity, and internal absorption activity. It has higher activity, better safety, wider pesticide spectrum, faster action speed, and longer effective period. In addition, there are other pesticides such as phoxim, high-efficiency cyhalothrin, etc., but you need to pay attention to the selection of suitable pesticides to avoid the use of organic phosphorus pesticides and high-efficiency cyhalothrin that is easy to cause allergy. It should be noted that different pests may have different reactions to different pesticides. Therefore, before using soil pesticides, it is best to understand the types of pests and choose the appropriate pesticide for spraying or soil treatment.
