Embodiment 1

[0016] A method of promoting seed germination and seedling growth of Lolium multiflora:

[0017] Matrix formula:

[0018] Element Dosage (parts by weight) soil 78 copies Pebbles 22 copies

[0019] Preparation:

[0020] Sow the ryegrass multiflora seeds directly into the nutrition pots with the substrate, sow 1-3 seeds per nutrition pot, cover the upper layer with 1.5-2.0cm of substrate, press lightly, place the nutrition pots on the seedbed, add water to the nutrition pots At the bottom 1-1.2 cm, the moisture completely infiltrates the substrate. Before emergence, add water at any time so that the moisture content of the substrate is 35-40%. The pretreatment is to take the soil and crush it through a 24-mesh sieve, and the diameter of the small stones after crushing is 0.5-0.7cm; put the above-mentioned pretreated materials in a mixing mixer, set the speed at 30r / min, stir for 1 hour, and then continue When stirring, add distilled water, contin...

[0022] A method of promoting seed germination and seedling growth of Lolium multiflora:

[0023] Element Dosage (parts by weight) soil 78 copies Pebbles 22 copies

[0024] Preparation:

[0025] Sow the ryegrass multiflora seeds directly into the nutrition pots with the substrate, sow 1-3 seeds per nutrition pot, cover the upper layer with 1.5-2.0cm of substrate, press lightly, place the nutrition pots on the seedbed, add water to the nutrition pots At the bottom 1-1.2cm, the water completely infiltrates the substrate. Before emergence, add water at any time to make the moisture content of the substrate 35-40%. After germination, the indole acetic acid IAA solution needs to be sprayed during the emergence process. The above-mentioned matrix is ​​prepared according to the following method: get the soil and pebbles of the formula amount and carry out pretreatment, and the pretreatment is to get the soil and pulverize a 24-mesh sieve, and the diamete...

[0027] A method of promoting seed germination and seedling growth of Lolium multiflora:

[0028] Element Dosage (parts by weight) soil 80 copies Pebbles 20 copies

[0029] Preparation:

[0030] Sow the ryegrass multiflora seeds directly into the nutrition pots with the substrate, sow 1-3 seeds per nutrition pot, cover the upper layer with 1.5-2.0cm of substrate, press lightly, place the nutrition pots on the seedbed, add water to the nutrition pots At the bottom 1-1.2cm, the water completely infiltrates the substrate. Before emergence, add water at any time to make the moisture content of the substrate 35-40%. After germination, the indole acetic acid IAA solution needs to be sprayed during the emergence process. The above-mentioned matrix is ​​prepared according to the following method: take the soil and pebbles of the formula amount and carry out pretreatment. The pretreatment is to take the soil and pulverize it through a 30-mesh sieve. Put t...

Abstract

A method for promoting the germination of ryegrass multiflora seeds and the growth of seedlings is to sow ryegrass multiflora seeds directly in a nutrient bowl equipped with a substrate, sow 1 to 3 seeds per nutrient bowl, and cover the upper layer with a substrate of 1.5 to 2.0 cm. Press lightly, place the nutrient pot on the seedbed, add water to the seedbed to 1~1.2cm from the bottom of the nutrient pot, the water will completely infiltrate the substrate, before emergence, add water at any time so that the moisture content of the substrate is 35~40%, after germination, spray indium Indoleacetic acid IAA solution. The invention can make the germination rate of ryegrass multiflora seeds high, which can be as high as 93%, the germination index is high, which can be as high as 53, the vitality index is high, which can be as high as 448 or more, the growth of seedlings is good, the whole plant of seedlings can reach more than 11cm, and the seedlings can The length is more than 8.4cm, the root length can be more than 2.5cm, the fresh weight of the whole plant can reach more than 4g, the fresh weight of the seedling can reach more than 1.48g, and the fresh weight of the root can reach more than 2.4g. The cycle is short, the method of the invention is simple and reliable, and is worthy of market promotion and application.

Description

technical field [0001] The invention mainly relates to the field of cultivation technology, in particular to a method for promoting seed germination and seedling growth of Lolium multiflora. Background technique [0002] Ryegrass multiflora (scientific name: Lolium multiflorum L.) has a plant height of 50-130 cm, soft leaves, dark green leaf color, long and narrow leaves. Studies have shown that: multiflora ryegrass has good feeding value, its leaves are tender and juicy, with many leaves and few stems, rich in carbohydrates, and its nutrients contain high sugar content and relatively high digestibility. Like to eat. In the southern part of our country, it can also be used as a raw material for silage. When other forage plants are in short supply, it provides high-quality feed raw materials for herbivores and plays a vital role in its agricultural structure. . For a long time, people have been paying more attention to the field management techniques of ryegrass multiflora...
