A kind of cultivation method of using gibberellin solution to promote the fast growth of young summer oak seedlings

Abstract

The invention belongs to the field of breeding and cultivation technology research of nursery stocks of garden tree species and particularly relates to a cultivation method for adopting gibberellins solution to promote fast growth of young common oak nursery stocks. The method comprises the following conventional steps of 1 sowing land selection, 2 land preparation for seedbed preparation, 3 seed screening and processing and 4 sowing and is characterized by further comprising the step 5 seedling management, the seedling management step includes the sub-steps that (1) a gibberellins solution with 85 ppm concentration is sprayed on the common oak nursery stocks when a first-time top-sealing phenomenon occurs on the common oak nursery stocks, the spraying amount is 40 L / mu, and the spraying times of the gibberellins solution is two; (2) two-years-old nursery stock management is performed, and a management mode is the same as the management mode of the previous year; (3) the gibberellins solution is sprayed at the daily mean temperature of higher than 24 or 25 DEG C in the wind-free time period before 10am or after 18pm. The technical problem of slow growth of the young common oak nursery stocks is solved, the production cost is remarkably reduced, and meanwhile the cultivation method is simpler in operation, more convenient to carry out and convenient to popularize and apply.

Description

Technical field [0001] The invention belongs to the research field of breeding and cultivation technology of garden tree seedlings, and specifically relates to a cultivation method for promoting the rapid growth of young summer oak seedlings by using a gibberellin solution. Background technique [0002] Quercus robur L., formerly known as Quercus robur, is a deciduous tree of the Fagaceae family Quercus L. with a height of up to 40m. Flowering in May, fruiting period from September to October. Summer oak is native to Europe, and was introduced into Xinjiang Yili, Tacheng and Urumqi from the former Soviet Union to cultivate it in the late 19th or early 20th century. It is an excellent landscaping tree species, industrial timber and special timber tree species for wine industry. [0003] Summer oak is a slow-growing tree species, especially the young seedlings grow slowly. The annual seedling height is only 12-30cm, and the 5-year seedling can reach 100-150cm. It only starts to acc...
