- 摘要:
- 以秦岭野生美味猕猴桃为试材，通过穴盘育苗与营养钵移栽，比较了温室与露地育苗出苗状况、不同加温措施（T1:25 ℃搭拱棚加温；T2:温室内不加温处理；T3:不加温7 d后移入加温棚）育苗状况、不同基质（Z1草炭∶蛭石=3∶2，另加复合肥1.0 kg?m-3；Z2草炭∶蛭石=4∶1，另加复合肥0.5 kg?m-3；Z3草炭）、不同时期移栽（S1:2片真叶时期；S2:3片真叶时期；S3:4片真叶时期）幼苗的生长状况。结果表明：猕猴桃温室育苗出苗快，出苗率95.56%、整齐度89.40%，均高于田间育苗；T1处理加温出苗快（9 d），在出苗率、整齐度、真叶数显著大于T2处理且高于T3处理；基质Z1在株高、地径显著高于基质Z2、Z3，根冠比最低。移栽时期S2地下部干质量最大，为0.84 g，与S1时期各测量生长指标无显著性差异，与S3差异显著。Z1S2组合株高、地径值最大，壮苗指数为1.159。
- Abstract:
- Qinling wild (Actinidia chinensis var.Deliciosa) was used as test material,the experiment was designed to study the emergence situation of kiwifruit in greenhouse seedling and field seedling,the effect of different heating measures(treatment 1,heating at 25 ℃under the small arch shed；treatment 2,no heating treatment；treatment 3,heating at 25 ℃ after 7 days no treatment) on kiwifruit seedlings growth and different substrate Z1(peat∶vermiculite=3∶2,adding compound fertilizer 1.0 kg?m-3),Z2(peat∶vermiculite=4∶1,addingcompound fertilizer 0.5 kg?m-3),Z3(peat) and transplanting date S1（two true leaves period）,S2（three true leaves period）,S3（four true leaves period） on kiwifruit seedling growth by plug seedling and nutritive tube transplanting seedling.The results showed that the emergence time of kiwifruit in greenhouse was fast,the rate of emergence was 95.56% and the uniformity of it was 89.40%,which were all higher than the field seedling；treatment 1 could promote the kiwifruit seedlings sprout and growth,shorten the emergence time,which was only 9 days lower than the treatment 2(18 days)and treatment 3(15 days).The emergence rate,uniformity and true leaf number of treatment 1 were much greater than treatment 2,higher than treatment 3；plant height,ground diameter of substrate Z1 had significant difference with Z2,Z3;the root shoot ratio of Z1 was the lowest；the transplant period of S2 had no significant difference with S1 in the measurement index of growth,but had significant difference with S2.S2 had the largest underground part dry weight value that was 0.84 g；the interactive combination Z1S2 had the largest value in main seedling growth index plant height and ground diameter,and the seedling index of it was 1.159.
