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.
