Embodiment 1

[0025] Treatment of plug seedlings after germination in autumn

[0026] The full-bodied japonica seeds picked in October were germinated under laboratory conditions. Seeds are placed in germination boxes, which are divided into three germination boxes, with 200 seeds in each germination box and a weight of 0.033g. Seeds that were germinated in October were germinated at 20°C in consideration of the low temperature for overwintering. When the radicle of the seeds grew 0.2-0.3 cm, they were immediately transferred to a 108-mesh seedling tray. The substrate was peat soil, river sand, and pastoral soil. The ratio of 3:1:1 is fully mixed, and 3 days before transplanting seedlings, the ratio of 1:500 times of Dixon powder is mixed with water, stirred evenly, and then watered and disinfected. When transplanting seedlings, put the substrate into the seedling tray, the amount of substrate loaded is equal to the upper surface of the seedling tray, and put 1 seed in each hole. After the...

[0028] Treatment of Seedlings in Greenhouses in Spring after Germination

[0029] Put the plum blossom seeds collected in autumn in paper bags to overwinter at room temperature, and germinate at the end of March next year. Seeds are placed in germination boxes, which are divided into three germination boxes, with 200 seeds in each germination box and a weight of 0.033g. Accelerate germination at 20°C, and when the radicle of the seed grows 0.2-0.3cm, immediately transfer it to a 108-mesh seedling tray. The substrate is fully mixed with peat soil, river sand, and garden soil in a volume ratio of 3:1:1. 3 days before transplanting seedlings, use Dixon powder in a ratio of 1:500 times and mix with water evenly, then water and disinfect. When transplanting seedlings, put the substrate into the seedling tray, the amount of substrate loaded is equal to the upper surface of the seedling tray, and put 1 seed in each hole. After the transfer, use a sprayer to spray atomized water on t...

[0031] Greenhouse seedling raising method for direct seeding in autumn

[0032]In October, weigh 0.1 grams of seeds, mix them with 200ml of fine dry sand, and spread them in the seedling trays. The seedling substrates are fully mixed with peat soil, river sand, and pastoral soil in a volume ratio of 3:1:1. After the substrate is sterilized with 500 times of carbendazim, it is sown. After sowing, it is covered with sandy soil of about 0.1 cm, and sprayed with atomized water until water seeps out of the water hole under the seedling tray, and the seedling substrate is fully soaked. Then put the soaked seedling tray directly into the plastic greenhouse. At this time, the temperature of the plastic greenhouse generally fluctuates around 16-20°C. Seeds began to germinate on the 10th day after sowing, and no more seeds germinated after 20 days. After 20 days, the statistical germination rate was only 39.5%. The seedlings survive the winter in the greenhouse. Due to the low temper...

Abstract

The invention provides a sowing and seedling raising method for mock orange. The method comprises the following steps: sprouting seeds of mock orange at 16-26 DEG C; instantly transferring to a seedling raising plate filled with matrix when embryo roots are of 0.2-0.3 cm; sprinkling atomized water for close integration of the embryo roots and the matrix. The seedling raising matrix is prepared by intensively mixing turfy soil, river sands and field soil with the volume ratio of 3:1:1; the seed surfaces are not needed to be covered with soil after transplanting; a hole tray is put into a greenhouse; in the seed germination stage, air humidity is controlled to be 90% or above, the temperature is controlled to be 16-22 DEG C, and moderate water management is carried out. The method improves both the seed germination rate and the seedling survival rate of mock orange by sprouting, sowing and seedling raising in autumn and winter, and provides the key technical reference for commercialized seedling raising of mock orange as the period of seedling raising is shortened within one year.

Description

technical field [0001] The invention belongs to the field of plant seedling raising in the agricultural field, and in particular relates to a method for sowing and seedlings of Prunus japonica. Background technique [0002] Prunus is a shrub plant with fragrant, beautiful, multi-focused flowers and a long flowering period. It is an excellent ornamental flower and tree. It is a widely distributed species in China, but there are not many reports on the research of Prunus japonica, only a small amount of reports on its pollen vigor (Liu Yingnan, 2011) and greenhouse seedling cultivation (Gao Xia, 2003), lack of its breeding technology research and application. The main mode of reproduction of the mountain plum is seed propagation. Carrying out research on sowing and seedling raising technology plays an important role in its mass production and promotion of market development. But its seed propagation is subject to the restriction of the following points: 1. The seed is small...
