Embodiment Construction

[0014] The specific implementation manner of the present invention will be described below with reference to the accompanying drawings.

[0015] The plant test of nanometer lignosulfonate preparation plant test that the present invention refers to is as follows:

[0016] Firstly, the nanometer sodium lignosulfonate preparation is prepared.

[0017] Add 4.0g of sodium lignosulfonate to the flask, fully dissolve it in 500ml of deionized water, then add an appropriate amount of sodium tripolyphosphate (STPP) with a concentration of 0.8mg / ml as a dispersant, at a constant temperature of 25°C Stir on a magnetic stirrer for 20 min, and adjust the solution to pH 7-8. Then put the solution into an ultrasonic cleaning machine for ultrasonic vibration treatment for 30 minutes (ultrasonic working frequency 80KHz, ultrasonic electric power 500W), to obtain nanometer sodium lignosulfonate preparation.

Abstract

The invention discloses application of a nano lignosulphonate preparation in promoting growth of plant seedlings. Deep researches on lignosulphonate show that the nano lignosulphonate preparation prepared on the basis of the lignosulphonate helps improve utilization efficiency of lignin and reduce the usage, thus growth of the plant seedlings is better promoted and heavy metals absorptivity is better. Plant seedling tests using the nano lignosulphonate preparation show that the nano sodium lignosulphonate of appropriate concentration has evident effect of promoting root length, seedling height and germination rate of wheat and mung bean seedlings; the nano sodium lignosulphonate preparation is more effective than the non-nano preparations. Comparison analysis on zinc stressed growth of the wheat and mung bean seedlings shows that processing with the nano sodium lignosulphonate helps increase plant root length, seedling height, germination rate, fresh and dry weight in growth at seedling phase, and leaf chlorophyll content, thus, zinc stress at seedling stage of the wheat and mung bean is relieved, and the resistance of plants to heavy metals is improved.

Description

technical field [0001] The invention relates to the application of a nano lignosulfonate preparation in promoting the growth of plant seedlings, in particular to the application of the nano lignosulfonate preparation in promoting seed germination and seedling growth. Background technique [0002] Lignin is a natural polymer material with a wide range of sources, low price and renewable utilization. It is the second most abundant organic matter in the world. It is usually used as a dispersant, adsorbent, cement crushing aid, dye additive in industrial processing , oil recovery additives, concrete water reducing agents, asphalt emulsifiers, etc. Studies have shown that industrial lignin also exhibits good adsorption performance. Lignin extracted from wheat straw can effectively adsorb chromium ions in water; lignin modified by methane sulfide can adsorb many harmful heavy metals in nitrate ion. [0003] Plant growth regulators are substances that have similar physiological a...
