There are many kinds of plants and rich resources in China. For a long time, scientists from Britain, France, Germany, the United States and many other countries have come to China to investigate plant resources and collect plant specimens. From 65438 to 1960s, the plant research in China was mainly controlled by foreigners, and a large number of specimens, including rare and type specimens, were exiled abroad. The research papers on plants in China were also written by foreigners. China has introduced modern botany twice and published and translated some foreign botany books. However, due to the shackles of feudal society for a long time, it has not been taken seriously. Until the beginning of this century, modern botany was still a blank in China. Money has long been dissatisfied with this situation. He believes that without the establishment of modern botany in China, how can we develop and utilize the rich plant resources of the motherland, how can we transform our backward agriculture and forestry and build a prosperous country?

Qian is full of passion for saving the country and is determined to plant his knowledge of modern botany on the land of the motherland faster, so that it can take root, blossom and bear fruit. At that time, he overcame many difficulties in manpower, material resources and financial resources and devoted himself to the establishment and development of modern botany research in China with great enthusiasm and perseverance.

His research field is very extensive and groundbreaking in many aspects. 19 16, "Two Asian Related Species of Ranunculus pennsylvania" was published abroad, which was the first time that China people named and classified plants in Latin. 19 17 published "Special Effects of Barium, Strontium and Cerium on Spirogyra" abroad, which is also the first document in China to study plant physiology by modern scientific methods. He also wrote China's paper "Plant Ecology and Geo-botany-A Preliminary Study on the Flora of Huangshan Mountain in Anhui Province" for the first time. Qian also selected plants of Orchidaceae, Urticaceae, Leguminosae, Ranunculaceae and other plants which are difficult to classify for the first time in China for systematic study. In order to spread new technology and scientific knowledge more quickly, he published an introduction to new methods of animal and plant microscopy on 19 17, and translated some papers on plant physiology on 1929. Most of Qian's early works and translations were published in Science, Journal of Institute of Biology, Chinese Academy of Sciences and Journal of Botany, China Academy of Sciences. In addition to the above articles, his publications such as Species and Distribution of Forests, Experiment of Plant Density, Natural Expression of Plants, Three New Species of Orchidaceae from Zhejiang and New Species of Plants from China were also representative works at that time. Qian's contribution to plant taxonomy, plant physiology, plant ecology and geobotany laid the foundation for the establishment of modern botany in China.

Money attaches great importance to field work. Shortly after returning to China, he went deep into Zhejiang and southern Jiangsu to study the flora and collected more than 65,438+0,000 plant specimens, especially those from Zhejiang Province. After the 1920s, the forests and rock plants in Zhongshan, Nanjing were observed and studied specially. He also worked out a plant investigation plan for Jiangsu, Zhejiang, Anhui and Sichuan provinces. The collection team he organized traveled all over the mountains and rivers in these areas and accumulated rich data, which opened the way for the study of plant classification, flora and vegetation in southeast and southwest China, and also created conditions for the compilation of regional flora, ethnic flora and phytogeography in the future. Through these investigation activities, Qian further realized the rich green treasure house of the motherland, broadened his horizons and strengthened his belief in devoting himself to science.
