The Edible and Medicinal Value of Coix lacryma-jobi and Key Cultivation Techniques for High and Stable Yield

In this paper, it was introduced that Coix lacryma-jobi is a traditional dual-use edible and medicine crops in China, and the nutritional components and medicinal value of Coix lacryma-jobi were described. Based on the published literature at home and abroad, a variety of chemical components found in Coix lacryma jobi and their medicinal effects were reviewed. At the same time, the problems existing in the production of Coix lacryma jobi were put forward. With the improvement of people’s living standards, the nutritional and health care value of Coix lacryma-jobi has been paid more and more attention. The problems of Coix lacryma-jobi in production were analyzed. Some biological characteristics of Coix lacryma-jobi, especially its hygrophyte characteristics, were re-recognized, which is very important to increase the yield of Coix lacryma jobi. In the paper, the key cultivation techniques for high and stable yield of Coix lacryma-jobi were also summarized. In order to obtain high quality, high and stable yield, we should adopt the new technical methods of “two wet, two dry and two water” in water management. At the same time, if artificial pollination is applied in the peak of flowering period, the seed setting rate and the yield will be increased.
