| 摘 要： | 在椰糠半无土栽培模式下以将军菊苣（品种编号：J-1、J-2、J-3和J-4）和食叶草（品种编号：S-1和S-2）为试材，分别进行株距（25 cm、30 cm、35 cm）和刈割间隔期（30 d、35 d、40 d）的栽培试验，探究了不同株距和刈割间隔期内两种牧草的叶片生长情况、刈割后的全株干鲜重和叶片的粗蛋白含量，明确了两种牧草的适宜株距和最佳刈割间隔，为牧草高产优质生产提供新途径。株距试验结果显示：当定植株距为25cm时，将军菊苣J-1品种的亩产较高；当定植株距为30cm时，S-1、S-2和J-4品种的亩产量、各品种的叶片数量（除J-4品种）、干物质含量（除S-1品种）、叶片粗蛋白含量（除J-3品种）高于其他株距组；当定植株距为35 cm时，将军菊苣的叶片宽度（除J-1品种）、全株鲜重、干重（除J-1品种）均较高；将军菊苣的各品种间的亩产量不同。刈割间隔期试验结果显示：间隔40 d刈割时，叶片长度和叶片数量（除J-4品种）、全株鲜重、干重和干物质含量均高于其他间隔期；间隔35 d刈割时，所有品种的叶片粗蛋白含量高于其他组。综上所述，在本试验条件下，食叶草的生产以株距为30 cm、刈割间隔期为40 d时可实现高产；以株距为30 cm、刈割间隔期为35 d时可实现优质生产。将军菊苣在株距为30 cm、刈割间隔为35 d时可实现优质生产

Study on Optimum Plant Spacing and Mowing Intervals of Leaf-eating Grass and General Chicory |
| |
| Abstract: | Under the semi-soilless cultivation mode of coconut bran, the cultivar of general chicory (variety No.J-1, J-2, J-3, J-4) and leaf-eating grass (variety No.S-1, S-2,) were used as the test materials which were cultivated by different plant spacing (25 cm, 30 cm, 35 cm) and mowing intervals (30 d, 35 d, 40 d) , to explore the appropriate plant spacing and mowing intervals, so that provide a new approach for high-yield and high-quality pasture production. The results of the plant spacing test showed that J1 obtained the highest yield when plant space set at 25 cm, whereas the yield, number of leaves (except J4), dry weight (except S1) and crude protein content (except J3) of S1, S2 and J4 were higher when plant space set at 30cm. When the plant space set at 35cm, the leaf width, dry weight (except variety J-1), and fresh weight of the whole plant were higher than those of other groups. The results of the mowing intervals test showed that the leaf length, number of leaves (except variety J-4), fresh weight of the whole plant, dry weight and dry matter content were higher than those of other interval groups at the mowing interval of 40 days. However, at the mowing interval of 35 days, the crude protein content of leaves was higher than that of other interval groups. In conclusion, through this study, the leaf-eating grass could obtain high yield when plant space set at 30cm and mowing at 40 d intervals, and both leaf-eating grass and general chicory could obtain better quality when plant space set at 30cm and mowing at 35 d intervals. |
