Embodiment 1

[0027] A method for raising seedlings in plug trays for improving the salt resistance of Ficus sessileus:

[0028] (1) Seed production: collect red or black ficus fruits with soft texture and the same maturity period, put them in plastic bags and store them at room temperature for 3 days, make the ficus fruits fully mature and soften, squeeze the ficus fruits, dry them in the sun, crush them, and collect them Sessile Ficus microphyllum seeds, sealed and stored at 4°C for later use;

[0029] (2) Plug sowing: Select a special seedling substrate, peat soil, vermiculite, and perlite in a ratio of 4:2:1, fill the mixed substrate into a 128-hole plug through an automatic plug filling machine, and place the treated banyan tree The seeds are put into the plug tray automatic seeder for sowing, and the soil is not covered after sowing;

[0030] (3) Disinfection of plug trays: Build a 10cm-high disinfection soaking pool with bricks, place a plastic film on the bottom of the pool, add 80...

Embodiment 2

[0034] Steps (1)-(4) are the same as in Example 1, and the H 2 o 2 , 5-aminolevulinic acid (ALA), and salicylic acid were replaced by 18 μmol / L of H 2 o 2 +20mmol / L 5-aminolevulinic acid (ALA)+0.08mmol / L salicylic acid, spray evenly on the leaves, treat once every 10 days, spray once on the leaves in the morning and evening, until the two-year-old seedlings are cultivated Out of the garden, colonization.

Embodiment 3

[0036] Steps (1)-(4) are the same as in Example 1, and the H 2 o 2 , 5-aminolevulinic acid (ALA), and salicylic acid were replaced by 23 μmol / L of H 2 o 2 +50mmol / L 5-aminolevulinic acid (ALA)+0.15mmol / L salicylic acid, spray evenly on the leaves, treat once every 10 days, spray once on the leaves in the morning and evening, until the two-year-old seedlings are cultivated Out of the garden, colonization.

[0037] Experiment 1 Effects of different concentrations of exogenous hormones on the salt tolerance of Ficus sessileus

[0038] Experimental method: After the salt stress treatment, the leaves of the seedlings were taken on the 1d, 5d and 15d to measure the H 2 o 2 After the exogenous treatment, the leaves of the seedlings were taken on the 15th day to measure the MDA content, SOD, POD enzyme activity, and the content of soluble sugar in the leaves of the seedlings, and each group repeated 3 times. SOD was determined by nitrogen blue tetrazolium method, POD activity wa...

Abstract

The invention relates to the technical field of forest tree seedling cultivation, in particular to a cultivation method for improving the salt tolerance of the seedlings of the Sessile Ficus microphylla after seedling cultivation in plug trays. Aiming at the problems of low asexual reproduction coefficient of Ficus sessileus, poor seedling growth potential, lack of natural tree shape, uneven germination time and growth, low work efficiency and high labor cost in existing sowing and propagation technology, it provides a fast , high-quality, low-cost industrial breeding method for Ficus sessileus seedlings, and at the same time, through the proportioning of exogenous hormones, improve the salt tolerance of Ficus sessileus, and finally obtain a method that can improve the salt resistance of Ficus sessileus The plug seedling raising method.

Description

technical field [0001] The invention relates to the technical field of forest tree seedling cultivation, in particular to a cultivation method for improving the salt tolerance of the seedlings of the Sessile Ficus microphylla after seedling cultivation in plug trays. Background technique [0002] Sessile Ficus genus Moraceae Ficus, as a native tree species in Zhejiang, is a unique landscape and ecological tree species in tropical and subtropical regions. It is also a large tree of the genus Ficus distributed in the northernmost edge of the southern subtropical zone. It is long-lived and evergreen. It is in the ecosystem. play a key role. In recent years, due to the needs of the construction of forest cities and garden cities and the improvement of urban beautification and greening projects, banyan trees have unique landscape effects such as majestic tree posture, dense shade, long-lived evergreen, etc., and they are also strong in salt, alkali, water and humidity. Therefore...
