Adjusting method capable of improving germination of small-grain vegetable seed

Abstract

The invention discloses an adjusting method capable of improving germination of a small-grain vegetable seed. The method comprises the following steps: 1) carefully choosing and weighing to-be-treated seeds; 2) preparing humic acid powder with a particle size of less than 40 meshes; and 3) fully mixing the seeds, the humic acid powder and water according to a weight ratio of 1: 1-2: 1-2 in an aluminum pot, standing the obtained mixture at a temperature of 10 to 20 DEG C for 1 to 7 d, then separating the seeds from humic acid and carrying out dehydration at a temperature of 25 DEG C until water content is less than 7%. According to the invention, the natural agriculture grade humic acid powder is employed as an adjusting medium, and the treated seeds have accelerated seed germination speeds and enhanced stress resisting ability in germination. The method is applicable to small-grain vegetable seeds of green vegetables, amaranth, etc.

Description

technical field [0001] The invention relates to seed treatment and seed physiological application technology, in particular to an adjustment method for improving the germination characteristics of small vegetable seeds. Background technique [0002] In the early spring sowing and seedling production of vegetable seeds, due to the low soil temperature, not only the germination is slow, but also quite irregular, and sometimes it takes too long. In 1973, Heydecker in the United Kingdom used osmotic agents to treat the seeds, allowing the seeds to slowly absorb water and prepare for germination physiologically and biochemically, but they could not get enough water to allow the radicle to germinate, and finally dried the seeds. The temperature can germinate neatly in a short time. This seed germination regulation method (Seed Priming) is also known as initiation in China. Beginning in the 1980s, domestic scholars have carried out research work on priming technology. At present,...

Problems solved by technology

[0003] The seeds of small vegetables such as green cabbage, amaranth, and lettuce have small particle sizes, generally below 1.5 mm. The existing priming methods are not suitable for this kind of seed germination regulation treatment. For example, the cost of PEG priming is high, and mass production is difficult, and the PEG solution is viscous. Inconvenient to clean and dry

Initiated by the sand solid matrix Due to the high density and high hardness of the sand, the seed embryo is easy to be damaged during the mixing process, so it is not suitable for the regulation of the germination of small vegetable seeds

Vermiculite caused by vermiculite is not easy to separate after treatment because the size of vermiculite is close to that of the seed, which reduces the cleanliness of the seed batch, which is not conducive to the sale of commercial seeds, and is not suitable for the regulation of germination of small vegetable seeds.
