Oriental cherry sowing and seedling raising method

Abstract

The invention provides an oriental cherry sowing and seedling raising method which includes the steps: S1 soaking collected mature oriental cherry seeds in clear water and then collecting the seeds sinking into the water; S2 drying the seeds in the shade, separately placing the seeds into plastic net bags, placing the plastic net bags into a flowerpot paved with fresh moist river sands, spreading the seeds in a scattered manner to form a plane, paving the plane with a layer of thin fresh moist river sands and repeatedly laying 3-4 layers of seeds in the flowerpot in such a manner; S3 placing the flowerpot into an indoor shade place, taking out the seeds in the plastic net bags every week, turning over the seeds once, timely removing mouldy seeds and timely supplementing water; S4 transferring the flowerpot to an outdoor rain shelter without direct sunlight in December, taking out and turning over the seeds in the plastic net bags every week, flushing the seeds with tap water once, and sowing the seeds after the seeds are split. The oriental cherry sowing and seedling raising method is applicable to large-scale oriental cherry sowing and seedling raising and has the advantages of neat seedling emergence, high germination rate, high survival rate and excellent seedling emergence quality.

Description

technical field [0001] The invention relates to the field of cultivation technology, more specifically, to a method for sowing and raising seedlings of cherry blossoms. Background technique [0002] Sakura (scientific name: Cerasus sp.): It is the general designation of several plants of the genus Sakura in the Rosaceae family. Cherry blossoms are trees, 4-16 meters high, with gray bark and lip-shaped lines. Branchlets lavender-brown, winter buds ovoid, glabrous. The leaves are ovate-lanceolate, with sawtooth on the edge, and the flowers are in bunches of 3-5 in umbels. When the cherry blossoms are in full bloom, the trees are unfolding freely and freely, with luxuriant flowers and branches, piled up with clouds and snow, like Yushu Qionghua, and the viewing effect is excellent. It is one of the world-famous early spring flower viewing trees. In addition, cherry blossoms can also be used medicinally or ediblely, such as for making sushi, processing and making pickles, etc....

AI Technical Summary

Problems solved by technology

The most commonly used method is grafting, but grafting has high technical requirements and is time-consuming and labor-intensive. In the early stage, a large number of rootstocks need to be propagated, and seedlings are generally propagated as rootstocks by sowing. In the later stage, rootstocks and scion varieties are not compatible. The risk of poor growth or even death of the scion variety is also present. There is also a large number of sprouts at the base of the rootstock, which need to be repeatedly degerminated to maintain the purity and vegetative growth of the scion variety. Moreover, the lifespan of cherry blossom seedlings produced by this propagation method is only a few decades. It is also the main reason for the short lifespan of cherry blossoms in China.

Cutting propagation has special requirements for soil formula, temperature and humidity, soil sterilization degree, rooting ability of cuttings, and fine management during cutting. few for breeding
