Problems solved by technology

However, if the technology disclosed in the prior art is used in the advanced cultivation technology of seedling cultivation and transplanting, there are often the following problems: 1. The effect of seedling growth and promoting root and strong seedling needs to be improved, and the effect is relatively slow, which cannot meet the needs of seedling cultivation. Technical requirements for transplanting
2. High concentration and high cost
4. The mode of action is relatively simple

[0022] Separately dissolve sodium nitrate, superphosphate, potassium sulfate, calcium chloride, magnesium sulfate, boric acid, zinc sulfate, manganese sulfate, and DPC, NAA, IBA, 6-BA, 2,4-D in water to dissolve The concentration of the above-mentioned compounds reaches the following ranges respectively (calculated with the content of 1 liter of solution):

[0023] (Sodium nitrate) N 0.022mol, (calcium superphosphate) P 0.001mol, (potassium sulfate) K 0.007mol, (calcium chloride, superphosphate) Ca 0.008mol, (magnesium sulfate) Mg0.002mol; boron 0.250mg boric acid, zinc sulfate containing 0.100 mg of zinc, manganese sulfate containing 0.250 mg of manganese, and DPC (benzyl amine crystal) 15 mg; NAA (α-naphthalene acetic acid) 1.0 mg, IBA (indole butyric acid) 2.0 mg, 6 - BA (6-benzylaminopurine) 0.1 mg, 2,4-D (2, 4-dichlorophenoxyacetic acid) 0.05 mg; then mix the completely dissolved above-mentioned compounds to obtain the root accelerator of the present invention.

Embodiment 2

[0025] Calcium nitrate, double superphosphate, potassium chloride, calcium chloride, magnesium sulfate, borax, zinc sulfate, manganese sulfate, and DPC, NAA, IBA, 6-BA, 2,4-D were dissolved in water separately, Make the concentration of the above-mentioned compound of dissolving reach following range respectively (calculate with the content of 1 liter of solution):

[0026] (Calcium nitrate) N 0.05mol, (double superphosphate) P 0.005mol, (potassium chloride) K 0.01mol, (calcium chloride, calcium nitrate, double superphosphate) Ca 0.01mol, (magnesium sulfate) Mg 0.005 mol; boric acid containing 0.50 mg of boron, zinc sulfate containing 0.2 mg of zinc, manganese sulfate containing 0.50 mg of manganese, and DPC (benzyl amine crystal) 15 mg; NAA (α-naphthalene acetic acid) 2 mg, IBA (indole butyric acid ) 5mg, 6-BA (6-benzylaminopurine) 0.2mg, 2,4-D (2,4-dichlorophenoxyacetic acid 0.1mg; then the above-mentioned compound that dissolves completely is mixed and obtains root promotin...

experiment Embodiment 1

[0029] With root promoting agent of the present invention described in embodiment 1 soaking cotton kind 8-12 hour, take Hongland nutrient solution soaking seed simultaneously as contrast, next day sow in the potted field of cultivation room of Cotton Research Institute of Chinese Academy of Agricultural Sciences, seedbed selects for use with vermiculite, The substrate mixed with fine gravel and river sand in a certain proportion, the temperature is controlled at 25-35°C, and the water is suitable. The seedling age is about 20 days to the stage of two leaves and one heart, and it is transplanted after 25 days. During the 5th, 9th, 13th, 18th, 24th, water the root-promoting agent solution (about 8 liters per square meter) of the present invention respectively, and contrast is Hongland nutrient solution. Before transplanting, the roots of the seedlings were soaked with the root-promoting agent of the present invention and the Hongland nutrient solution for 20 minutes respectively,...

Abstract

The invention relates to a root accelerant for accelerating the growth of new roots for plant seeds, root system or cottage organs, which comprises plant growth regulator, macronutrient and minute quantity nutriment elements, wherein said plant growth regulator includes DPC, 1-naphthalene acetic acid, indoxylic butanoic acid, 6-benzyl amino leucon and 2,4-Dichlorophenoxyacetic acid. The invention also relates to the process and usage of the root accelerant.

Description

technical field [0001] The invention relates to a root-promoting agent, in particular to an agricultural composition capable of promoting rapid rooting of plant seeds or cutting organs in seedbeds and / or fields, increasing new roots, and its preparation method and application. Background technique [0002] In the past two decades, the production and cultivation techniques of various forest trees, food crops and fruits and vegetables have been continuously improved, which has effectively promoted the development of productivity. For example, seedbed cultivation and transplanting is an advanced cultivation technology that can promote rapid and early maturity of plants, increase yield, and enhance quality. It has brought significant economic and social benefits, and has great and far-reaching significance in current cultivation and production. [0003] However, with the development of the times, many problems have also occurred in seedling transplanting. For example, 1) the see...
