Abstract

The invention discloses a seedling raising regulator for vegetables and a seedling raising method of vegetable strong seedling and particularly relates to a seedling raising regulator for vegetables which contains 5-aminolevulinic acid and derivatives thereof, naphthaleneacetic acid sodium, sodium nitrophenolate, epibrassinolide, levulinic acid and weakly acidic electrolyzed oxidizing water, wherein, the ratio, by weight, of 5-aminolevulinic acid and derivatives thereof, naphthaleneacetic acid sodium, sodium nitrophenolate, epibrassinolide and levulinic acid is 1:1-4:5-10:10-16:1-6, the dosageof the weakly acidic electrolyzed oxidizing water is 25-75mL relative to 5 milligrams of aminolevulinic acid and derivative thereof,. The invention also relates to a seedling raising method of vegetable strong seedling. By mixing the seedling raising regulator for vegetables and a seedling raising matrix, the vegetable seedling raising can be carried out, and the growth state of the vegetable seedlings can be obviously improved under the moderate temperature and light condition.

Description

technical field [0001] The invention belongs to the technical field of promoting high-yield cultivation of plants, and in particular relates to a vegetable seedling raising regulator and a method for growing vegetable seedlings strong. Background technique [0002] According to the data of the National Bureau of Statistics, in 2015, the sown area of ​​vegetables in my country was 21.9996 million hm 2 , where most of the solanaceous vegetables, cauliflower, lettuce and other vegetable varieties need seedlings. However, in the solar greenhouse in northern my country, there has been a long-term suboptimal temperature and light environment (10-18°C / 6-12°C, 160-300μmol·m -2 ·s -1 ), resulting in tall seedlings and weak seedlings prone to appear in the seedling raising process. As the saying goes, "50% of the harvest is good for seedlings", and the seedlings' physical fitness is weak, which seriously affects the later growth and yield quality. [0003] Therefore, be badly in n...
