摘 要: | 采用种衣剂拌种进行沙棘育苗试验,当年秋季进行沙棘苗生长量和苗木产量的调查,探讨种衣剂拌种对沙棘种子繁苗效果的影响。结果表明:包衣剂拌种能够显著提高沙棘苗木生长量,比对照多繁育27万株·hn-2;种衣剂拌种后繁育的苗木苗高、地径与对照差异显著,苗高比对照提高48.65%,地径提高33.34%;主根长较对照提高43.7%,差异达极显著水平;侧根数提高18.8%,差异不显著;种衣剂拌种后沙棘苗木根系腐烂率为8.9%,比对照低4.3个百分点。种衣剂拌种是半干旱区繁育沙棘优质苗木的有效技术措施。

Abstract: | Seedling-raising experiments of Hippophae rhamnoide were conducted by mixed seed coating agent . Growth yield of Hippophae rhamnoide seedlings in the very Autumn were investigated .The effects of seed coat-ing agent on propagation of Hippophae rhamnoides seedlings were discussed .Result shows that :seed coating a-gent with mixed seeds can significantly increase yield of Hippophae rhamnoide seedlings and breed two hundred and seventy thousand trees per hectare ;the seedling height ,ground diameter of the seedlings after mixing have significant differences with CK (seedling height ground diameter increase by 48 .65% 33 .34% ,respectively than CK );the length of the main root increase by 43 .7% and its difference reach extreme significant level ;the length of the lateral root increase by 18 .8% and its difference is not significant ;root rotting rate of Hippophae rhamnoide seedlings af-ter mixing is 8 .9% and is 4 .3% lower than that of CK ;using seed coating agent is an effective measure for breeding superior seedlings in semiarid region . |
