experiment example 1

[0025] The crop root rejuvenating agent provided by the present invention, 2,4-D and clear water were respectively applied to different groups of tomatoes cultivated in the soilless cultivation experiment greenhouse, and the treatment method was quantitative watering of the tomato root matrix. At different times of processing, measure the tomato root vigor, photosynthetic intensity and plant growth situation of each treatment group and measure its final yield, and compare the data of each treatment group to confirm that the crop root system rejuvenation agent provided by the present invention can rejuvenate the plant root system, improve Photosynthetic efficiency, promote plant growth and increase tomato yield.

[0026] The content of each component of the crop root rejuvenating agent used in the experiment is: 1 part by weight of mononitrated sodium guaiacol and 1.2 parts by weight of naphthalene acetic acid, which are dissolved in 70 parts by weight of distilled water.

experiment example 2

[0041] Apply the crop root system rejuvenating agent provided by the present invention with different dilution multiples to different groups of tomatoes cultivated in the soilless cultivation experiment greenhouse, compare the tomato root system activity, photosynthetic intensity and final yield between each treatment group, to determine that the invention provides The appropriate application rate of root rejuvenation agent.

[0042] The content of each component of the crop root rejuvenating agent used in the experiment is: 1.26 parts by weight of mononitrated sodium guaiacol and 1.05 parts by weight of naphthalene acetic acid, which are dissolved in 70 parts by weight of distilled water.

[0043] Take the cultivated tomato and set up 3 treatment groups. Treatment groups 1, 2, and 3 were treated with 3000-fold dilution of the root rejuvenation agent, 1 L of the 4000-fold dilution of the root rejuvenation agent and 1 L of the 2000-fold dilution of the root rejuvenation agent. ...

experiment example 3

[0049] Apply the crop root system rejuvenating agent provided by the invention and its individual components to different groups of tomatoes cultivated in the soilless cultivation experiment greenhouse respectively, measure the plant root system activity, plant photosynthetic efficiency and tomato yield of different treatment groups, and the measured data of each treatment group A comparison is made to determine that the root system rejuvenating agent provided by the invention is more effective in enhancing plant root system activity, plant photosynthetic efficiency and improving tomato yield than each component applied alone as a composition.

[0050] The content of each component of the crop root rejuvenating agent used in the experiment is: 1.5 parts by weight of mononitrated sodium guaiacol and 0.8 parts by weight of naphthalene acetic acid, which are dissolved in 70 parts by weight of distilled water.

Abstract

A root system rejuvenating agent for agricultural crops is prepared from mononitrified guaiacol sodium (1-1.5 Wt. Portions), naphthaleneacetic acid (0.8-1.2) and distilled water (70). It has high effect to greatly increase yield of agricultural crops.

Description

technical field [0001] The invention relates to a plant growth regulator and its application method during plant growth, in particular to a crop root rejuvenating agent and its application method. Background technique [0002] In the traditional vegetable planting mode, because some crops, such as tomato, have obvious seasonal growth characteristics and are not easy to store, their supply also shows obvious seasonal characteristics. In recent years, with the rapid development of greenhouse area and the widespread application of long-season crop cultivation techniques (one crop per year), this problem has been alleviated to a certain extent. However, crops cultivated in long seasons. For example, tomato is prone to premature plant senescence, which is mainly manifested in the reduction of plant root activity and low fruit setting rate, which directly leads to a decrease in yield. In the case of normal plant growth, the problem of low fruit setting rate can be solved by dipp...
