| 摘 要： | 选择本土、江沙、江沙＋平膜、江沙＋平膜＋拱膜4种覆盖方式，研究了覆盖方式对枳繁育的影响，结果表明：江沙＋平膜＋拱膜覆盖能有效提高枳壳幼苗的生长，枳出苗床移栽时，其株高和主根长分别是本土覆盖的1．58倍和1．20倍；与本土、江沙、江沙＋平膜覆盖相比，使用江沙＋平膜＋拱膜覆盖有效地改善了幼苗生长的微环境，尤其与本土覆盖相比较，土温提高了2～4℃，土壤湿度提高了5％～8％，空气温度提高了3～5℃。

| Abstract: | Abstract ： The author studied the effects of four different covering ways （ covering the seedlings with local soil, river sand, riv er sand ＋ flat film, river sand ＋ flat film ＋ arch membrane） on the seed emergence and seedling growth of Poncirus trifoliate. The results showed that covering with river sand ＋ flat film ＋ arch membrane could effectively promote the growth of seedlings, and the plant height and taproot length of the transplanted seedlings in this treatment were respectively 58% and 20% higher than that in the treatment of covering with the local soil. In comparison with other 3 covering ways, covering with river sand ＋ flat film ＋ arch membrane effectively improved the mini - environment of seedling growth, and the soil temperature, soil relative humidity and air temperature were increased by 2 - 4 ℃, 5% - 8% and 3- 5 ℃ respectively as compared with covering with the local soil. |
