example 1

[0016] Experimental purpose: To study the effect of nano-lanthanum hydroxide on indoor corn growth.

[0017] Test crop: corn (Nongda 108)

[0018] Test method: seed dressing, soil cultivation test

[0019] Experimental design and treatment: select relatively consistent seeds, soak them in water for 24 hours, and then dry them in the shade for 2 hours, then weigh different weights of lanthanum hydroxide for seed dressing treatment, that is, put the weighed lanthanum hydroxide in a beaker, and then put the lanthanum hydroxide Put in the seeds with known dry weight and dry in the shade, shake until the lanthanum hydroxide can evenly adhere to each seed, and then sow. The experiment consisted of 6 treatments with 3 repetitions.

[0047] Purpose of the experiment: To study the effect of nano-cerium hydroxide on the yield of field corn.

[0048] Test crop: corn (Nongda 108)

[0049] Test method: seed dressing, field test (sowing method and field management are the same as local customs)

[0050] Test treatment: select relatively consistent seeds, soak them in water for 24 hours, dry them in the shade for 1 hour, and then weigh different weights of rare earth compounds for seed dressing, that is, put the weighed rare earth compounds in a beaker, and then put the weighed seeds into , shake until the rare earth compound can be evenly attached to each seed, and then sow. The experiment set up 5 treatments, repeated 3 times, and the content of cerium oxide in the treatments T2 and T4, T3 and T5 was the same.

[0066] The purpose of the experiment: To study the effect of nanometer neodymium hydroxide on the yield of field cotton.

[0067] Tested crops: Cotton

[0068] Test method: seed dressing, field test (sowing method and field management are the same as local customs)

[0069] Test treatment: select relatively consistent seeds, soak them in water for 24 hours and dry them in the shade for 2 hours, then weigh different weights of neodymium hydroxide for seed dressing treatment, that is, put the weighed neodymium hydroxide in a beaker, and then put the weighed Put in the seeds, shake until the neodymium hydroxide can be evenly attached to each seed, and then sow. Three treatments were set up in the experiment, repeated three times, and the contents of neodymium oxide in treatments T2 and T3 were equal.

Abstract

The present invention belongs to application of nano rare earth hydroxide in plant field. It is characterized by that after the single or compounded nano rare earth hydroxide is undergone the following three treatment processes, it can be used in the plant growth process, said three treatment processes are as follows: (1) according to a certain proportion using nano rare earth hydroxide to dress or coat the soaked seed; (2) making nano rare earth hydroxide into suspension to make foliage spray or adding the nano rare earth hydroxide into foliage fertilize to make foliage spray; and (3). according to a certain ratio adding nano rare earth hydroxide into single-element fertilizer, composite fertilizer, organic fertilizer, micro fertilizer and other fertilizers as basic fertilizer and additional fertilizer.

Description

technical field [0001] The technical field of the present invention is the application of nano rare earth hydroxides in the field of plants. Background technique [0002] Nanotechnology is an emerging technology that was born in the late 1980s and developed rapidly. Its basic connotation refers to the study of atoms and molecules with a scale of 1 to 100 nanometers. The technology of rearranging and combining to form new substances and manufacture materials or devices with new functions. As early as 1959, the famous theoretical physicist and Nobel laureate Fermi once predicted: "There is no doubt that when we can manipulate things on a small scale, it will greatly expand the scope of our possible physical properties. "Qian Xuesen, a famous Chinese scientist, also predicted: "Nano and nanostructures will be a key point in the next stage of scientific and technological development, and will be a technological revolution, which will be another industrial revolution in the 21st...
