薏苡饲料资源开发和利用的研究——栽培试验及营养分析

ASTUDY ON THE EXPLOTATION ANDUTILIZATION OF COIX LACLYMA-JOBIL──an experiment on its cultivation and the analysis of its nutrition

本研究对薏苡设不刈青和刈青一次共两种处理方式,分析其生物产量以及籽实产量之间的差异性.并且分别与传统的饲料玉米作了对比试验.结果表明,薏苡的生物产量每亩为5054.9kg,墨白一号玉米40O9.6kg和凤引一号玉米3813.6kg.籽实产量,未刈青的薏苡为243.4kg,刈青后的180kg,后者的百籽重明显的超过前者(21:24.6g).又对鲜全株薏苡,青刈玉米的营养分析表明,两者的粗蛋白(7.65:2.58)、粗脂肪(5.02:0.81)、钙(1.57:0.06)、磷(0.32:0.05)无氮浸出物(48.1:20.09)、及粗灰分(9.60:1.99)的百分比含量显著超过后者.

<ABSTRACT>: In this study, in order to analyze the difference between the biotic and the seed output, twoways are used in dealing with the coix,one is to mow the greens,the othar is not to mow the greens Andcomparative experiments are made with the traditional corn feed material. The results show as follows; Thebiotic ortput of coix is 5054. 9kg per mu,while MuBar I corn, 4009kg per mu,and Feng Ying I corn 3813.6kg per mu, The seed output of coix without mowing the greens is 243. 4kg per mu, while after mowing thegreens, is 180kg per mu. But the weight per one-bundred seeds of the latter is comparatively heavier thanthat of the former(21g: 24. 6g)The nutrition analysis to the green entire Job's tears and the green-mow cornshow that the content in terms of percentage of the former is much more than that of the latter The crudeProtein (7. 65: 2. 58),the crude lipid (5. 02: 0. 81),the calcium (1. 57 ; 0. 67),the phosphorus (0. 32: 0. 05),thenitrogen -free extract (48. 1: 20. 09)and the crude ash (9. 6: 1. 99)
