Studies on the Suitable Seeding Time and Heat Index of Liaoshou-Peanut 15
摘要
Abstract
In order to provide the climate information for release and cultivation of new peanut varieties, the best seeding time and heat index of Liaoshou-Peanut 15 were studied by 5-year experiments during 2004 -2008. Results showed that it was suitable for seeding of Liaoshou-Peanut 15 in Liaoyang area when mean daily temperature increasing steadily to above 12℃. The suitable seeding period was April 15 -20,while the best seeding period was April 20 - 25. The growth period of Liaoshou-Peanut 15 was about 154 d, and its accumulated temperature was beyond 3 200 ℃ with a daily temperature higher than 12 ℃. The indexes of accumulated temperature during various developmental stages differ greatly, including 250 ℃ from seeding to emergence, 550 ℃ from emergence to primary blossom, 630 ℃ from primary blossom to late blossom,and 1 650 ℃ from late blossom to maturation. Liaoyang is rich in heat energy,which has the advantage of cultivation of Liaoshou-Peanut 15.关键词
