Study on Liquid Special Fertilizer for Drip Irrigation of Sugarcane and Its Irrigation Mode in Guangxi Lateritic Red Soil Region

[Objective] Liquid special fertilizer for drip irrigation of sugarcane was de- veloped and the fertilizer patterns were explored in the production to provide techni- cal support for fertigation production of modern agriculture. [Method] ROC22 was selected as experimental material, two formulas of liquid special fertilizer for sugar- cane developed by the cooperation between Guangxi Academy of Agricultural Sci- ences and New Orientation （Guangxi） Chemical Industry Co.,Ltd. were selected, namely, balanced 21-21-21 ~ TE of Xinfangxiang and hyperkalemic 13-6-39-TE of Xinfangxiang. Taking conventional fertilization as the control （CK）, two modes of ap- plying base fertilizer at the earlier stage ＋ fertigation in the tillering stage and ferti- gation in the whole growth period were set. [Result] The two modes of fertilization had not significant effects on the emergence of sugarcane, but applying base fertil- izer at the earlier stage ＋ timely applying water soluble fertilizer in the tillering stage was conducive to the tillering of sugarcane. Harvest results showed that the effects of different treatments on plant height and yield were significant, in which the yield of sugarcane under the treatment of hyperkalemic water-soluble fertilizer increased by 13.04% compared with conventional treatment, and the income increased by 4 500 yuan/hm2, [Conclusion] Liquid special fertilizer for drip irrigation of sugarcane signifi- cantly promoted the growth of sugarcane, moreover, under the same condition, the effect of hyperkalemic water-soluble fertilizer was better.

An Analysis of English Majors＇ Leaming Motivation in Newly-Founded Universities- A Case Study of Ningbo Dahongying University＊

Motivation is an inner state that arouses individual＇s desire for a goal and maintains their efforts in a certain direction and time. By analyzing the current situation of motivation problems for English majors in Ningbo Dahongying University, the author puts forward some suggestions on strengthening learners＇ motivation with a view to developing the learners＇ autonomous learning abilities. The author finds that using the content of regular college classroom teaching as a meaningful context for the development of responsibility can enhance the learning effect. The teacher＇s guiding role in autonomous learning should never be ignored.

Erythropoietin： From a Biosimilar to Innovative Products Protected by Industrial Property Assets

Aim： EPO （erythropoietin） is a hormone that stimulates the erythropoiesis and is mainly produced by the kidneys. In the early 1990s among the emerging biotech drugs, the recombinant human EPO （rhEPO） was the best-selling product worldwide, reaching nearly three billion dollars annually. The CIM （center of molecular immunology） produced and sold the rhEPO as commercial strategy to recover the investment made in its new facilities. This work summarizes the inventions that protect the innovative products developed by three Cuban institutions, starting from rhEPO, and the industrial property strategy followed by them. Methods： The information was obtained from the United States Patent, Trademark Office （USPTO） database, Patentscope, Espacenet, patent databases of Center for Pharmaceutical Research and Drug Development （CIDEM） and Cuban Industrial Property Office. Conclusions： The manufacturing process of CIM＇s EPO has its own patent family. From a manufacturing by product an innovative formulation protected by patent was obtained. There is a patent family around the nasal formulation and it continues enlarging. From a biosimilar pharmaceutical innovative products impacting on human health have been obtained.
