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 cultivati

Embodiment 1

[0039] The fruit is collected after ripening, left for about 20 days to make the flesh rotten, and cleaned. Use a sunshade net to make a pocket or a mesh plastic woven bag, and pack the fruit core; in alpine mountainous areas with an altitude of 1600 and an average temperature of 5°C In an open-air environment, use bricks to build a brick trough with a slope at the bottom, take acidic humus soil with a pH of 5 mixed with rotten leaves and sandy loam soil, spread 20 cm of humus soil on the first layer in the brick trough, and then lay the bagged doves flat The distance between the tung tree seeds, the bagged seeds, and the distance between the seeds and the bricks is greater than 10 cm. Put a layer of Davidia involucrata seeds and spread a layer of 10 cm thick humus soil. Layer 20 cm of humus soil, drench it with acidic water with a pH of 5 every 20 days, then let it freeze naturally, store it for 2 months until the shell of Davidia involucrata seeds is basically crisp; choose w...

Embodiment 2

[0041] After the fruit is ripe, collect it, remove the shell of Davidia involucrata with a machine that removes the shell from the walnut, and clean it. Use a sunshade net to make a pocket or a mesh plastic woven bag, and pack the core into the bag; store it in a cold storage at 0°C with a brick yard A brick trough with a slope at the bottom, take acidic humus soil with a pH of 5.5 mixed with rotten leaves and sandy loam soil, spread 20 cm of humus soil on the first layer in the brick trough, and then lay the bagged Davidia involucrata seeds and bagged seeds The distance between the seeds and the bricks is greater than 10 cm. Put a layer of Davidia involucrata seeds and spread a layer of 10 cm thick humus soil. After placing the Davidia involucrata seeds in turn, spread a layer of 20 cm humus soil on top. After that, drench it with acid water with a pH of 5.5 every 20 days, then allow it to freeze naturally, store it for 2 months until the shell of Davidia involucrata seeds is ...

Embodiment 3

[0043] The fruit is collected after ripening, placed for about 30 days to make the pulp rot, and cleaned, and made into a pocket or a mesh plastic woven bag with a sunshade net, and the fruit core is bagged; in the cold storage at -1.5°C, use a brick to code one For the brick trough along the slope at the bottom, take the acidic humus soil with a pH of 6 mixed with rotten leaves and sandy loam, spread 20 cm of humus soil on the first layer in the brick trough, and then lay the bagged Davidia involucrata seeds and the bagged seeds If the distance between the dove tree seeds and the bricks is greater than 10 cm, put a layer of dove tree seeds and spread a layer of 10 cm thick humus soil. After placing the dove tree seeds in turn, spread a layer of 20 cm humus soil on top. Drench it with acidic water with a pH of 6 every 20 days, then allow it to freeze naturally, and store it for 2 months until the shell of Davidia involucrata seeds is basically crisp; choose well-drained, fertil...

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...
