High survival seedling method of dove trees

Abstract

The invention discloses a high survival seedling cultivation method of dove trees. The method comprises the following steps: A, removing fruit fleshes; B, crisping fruit seed shells; C, cultivating seed buds; D, transplanting seedlings. The method provided by the invention cultivates the seedlings through the four steps of removing the fruit fleshes, crisping the fruit seed shells, cultivating theseed buds and transplanting the seedlings, wherein the fruit flesh removing step refers to removing the fleshes of dove tree fruits quickly and then putting the fruits into a woven bag for preventingbeing eaten by rodents and having good air permeability; the fruit seed shell crisping step refers to crisping or even cracking the seed shells of the dove tree fruits in the shortest time by adopting the freezing acidolysis technology, therefore dove tree seeds fast meet the requirements for budding; the seed bud cultivating step refers to protecting the dove tree seeds to have smooth budding under the environment of water drainage and waterlogging prevention by adopting the technologies of sterilization, anti-freezing, and the like, thereby increasing the bud rate of the seeds. The method carries out special treatment to the outer fruit fleshes and the inner seed shells, thereby fastening the budding time of the seeds and improving the survival rate of the dove tree seedling cultivation.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for raising seedlings of Davidia involucrata seeds with high survival rate. Background technique [0002] Dove tree is a deciduous tree. It can grow to a height of 15-25 meters, and the leaves are broadly ovate with serrated edges. There are only one genus and two types of plants in this family, and the two are similar, except that one has hairy leaves, and the other is smooth. Sehuaqimei is a relict plant left by the Cenozoic Tertiary period 10 million years ago. During the Quaternary glacial period, most of the dove trees became extinct one after another, and only some areas in southern China survived. It has become today's "living fossil" in the plant world. Because its flower shape resembles a flying dove and its flower head resembles the head of a white dove, it was named "Chinese pigeon tree" by western botanists, also known as "pigeon f...

Problems solved by technology

[0004] Existing methods for cultivating Davidia involucrata seedlings include sprout cultivation method, cutting seedling cultivation method and seed cultivation method. The advantage of the bud cultivation method and the cutting seedling cultivation method is that the survival rate is relatively high, but the technological process is complicated and the workload is large when a large amount of cultivation is carried out. The process of seed cultivation method is simple, and the workload is not large during a large number of cultivations, but the disadvantage is that the survival rate is low and the cultivation period is long. Therefore, in order to cultivate a large number of Davidia involucrata seedlings, a kind of Doveia involucrata seedlings can be developed to shorten the cultivation period and improve the survival rate of seed cultivation. Tung seedling raising method is of great significance
