Embodiment 1

[0017] Embodiment 1 Seed seedling cultivation

[0018] In Hangzhou area, in March to April, the infructescences (with branches) of Nanchuan Liu were collected, and then the infructescences were spread out on paper in a cool and ventilated room, and the capsules were cracked, and the impurities were removed with a sieve to obtain pure seeds. The experimental farm of Zhejiang University was chosen as the nursery ground, deep plowed and finely ground, and the seeds were drilled without covering the soil. After sowing, spray water. After 2~3, seedlings emerged one after another. The emergence of this method is irregular, and it is easy to cause the seedlings to die, the demand for seeds is large, the emergence is low, the labor intensity is high, and it needs to be transplanted and fertilized.

Embodiment 2

[0019] Example 2 Growing Seedlings by Cutting Fruit Branches

[0020] When the seeds of Nanchuan willow are mature (March to April in Hangzhou), the fruit branches are collected with pruning shears. In the experimental farm of Huajiachi Campus of Zhejiang University, the seedlings are selected, deep plowed, and the prepared seedbeds are leveled, and the fruit branches are directly harvested. Insert it so that the fruit branches are evenly distributed on the seedbed, let the capsules crack naturally, and the seeds naturally fall to the seedbed. This method is easy to operate and reduces labor intensity, but the seedling raising efficiency is low, and the seedlings are easily diffused due to wind blowing, which reduces the emergence rate.

Embodiment

[0021] Example 3 Nutrient floating seedling cultivation

[0022] To collect seeds, it is April in Hangzhou area. When the ears of Nanchuan willow turn light yellow and the seeds of flying catkins are first spewed, it is the best time to collect seeds. Take it back and put it in a dry place, so that the ears will crack naturally, and whipped with thin strips to speed up the cracking.

[0023] Select the seeds, sieve the seeds with a 5mm sieve, filter out the white fluff, and get the pure Nanchuan willow seeds.

[0024] Choose seedling trays and plastic pots. Choose a seedling tray (60 cm long, 30 cm wide, and 3 cm thick) and a plastic pot (64 cm long, 40 cm wide, and 5 cm thick) with holes at the bottom, and place a layer of gauze on the bottom to prevent substrate leakage

[0025] To prepare the substrate, mix peat soil and vermiculite with a volume ratio of 1:1, then fill it into the seedling tray, and then compact the substrate.

[0026] Preparation of nutrient solution...

Abstract

The invention provides a method for propagation of salix rosthornii seeds. The method comprises the steps of collecting the salix rosthornii seeds in a salix rosthornii seed mature season, utilizing a porous seedling culture disc, a matrix and nutrient solution to perform float breeding, and performing secondary transplantation when salix rosthornii seedlings are 5-10cm high. The seeds of the ecological salix rosthornii are rapidly cultured, the method is simple to operate, the occupied space is small, the seedling culture amount is large, the operation is extremely simple, repeated watering is not needed, seedling breeding and the like can be performed rapidly, the seedling culture survival rate is high, and the seedlings emerge quickly; the nutrient solution is supplemented, the seedlings are strong, the growth vigor is high, root systems are prosperous, the seedlings are easy to transplant, labor intensity is greatly reduced, seedling culture time is shortened, and seedling culture efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and relates to a method for propagating seeds of an ecological tree species-Nanchuan willow, including methods for collecting seeds of Nanchuan willow, preparing net seeds and substrates, and raising seedlings by nutrient floating. Background technique [0002] Nanchuan willow ( Salix roshornii Seemen.) is a small deciduous tree with a height of 5-10m, with thicker, dark brown branches, oval leaves, and stipules; spring and autumn tender leaves and twigs are red. Catkins, flowers with ventral glands and dorsal glands, varied in shape, often combined into multi-lobed discs; capsule ovate. The flowering period is from late March to early April. It is mainly distributed in southern Shaanxi, southeastern Sichuan, Guizhou, Hubei, Hunan, Jiangxi, southern Anhui, Zhejiang and other places in mainland China. It often grows beside water in hills, plains and low mountains. Because the type s...
