摘要
通过对薏苡（ＣｏｉｘＬａｃｒｙｍａ－ｊｏｂｉＬ．ｖａｒ．ｆｒｉｕｍｅｎｔｅａｃｅＭａｋｉｎｏ）的植物学特征、生物学特性和高产栽培技术进行研究，提出亩产４００～５００ｋｇ，需选用矮秆小粒品种和肥水条件良好的地块，每亩留苗５５００～１１０００株，亩施纯Ｎ１８．７～２３．５ｋｇ，Ｐ２Ｏ５１２．４～１４．６ｋｇ，Ｋ２Ｏ２２．２～２４．７ｋｇ。
Studies on botanical and biological characteristics and high-yield culture techniques of Coix lacryma-jobi L.var. friumenteace Makino showed that the key points to get 400-500 kg grains per mu or 6000-7500 kg ha-2 were (i) using short-stalked varieties with small grain, (ii)selecting fertile field with good irrigation conditions, (iii) retaining 5500- 11000 plants per mu, and (iv) applying pure nitrogen 18. 7- 23.5 kg, P2O5 12. 4- 14. 6 kg, K2O 22. 2-24. 7 kg per mu.
