Embodiment

[0042] The present invention has carried out a breeding test using Atractylodes macrocephala, and the test results show that the present invention can greatly increase the yield of Atractylodes macrocephala. The test process and results are briefly listed as follows:

[0043] 1. On March 15, 2010, 12.5 kg of Atractylodes macrocephala seeds were equally divided into 5 samples, 4 of which were irradiated in 4 different modes, and the other was not irradiated. The equipment used for irradiation is UHR-2000 microwave hyperthermia machine, and the irradiation frequency is 915MHz±30MHz. Other irradiation parameters are detailed in the table below.

[0044] 2. On April 24, 2010, the seeds were sown in the Lianyun Mountain Atractylodes Seedling Base, Longmen Town, Pingjiang County, Hunan Province, and the same cultivation conditions were adopted. The cultivation conditions are briefly listed as follows: the altitude of the base is about 50m; there is no greenhouse for outdoor cultiva...

Abstract

The invention discloses a far field microwave breeding method, which comprises the following steps of: regularly irradiating active seeds of a crop by using far field microwave, and stimulating the potentials of the active seeds by using energy memory effect to obtain optimized active seeds of the crop with high yield increasing effect. Experiments such as large-headed atractylodes rhizome breeding and the like show that the method has remarkable advantage on the aspect of improving the yield compared with other methods for obtaining optimized active seeds of crops, the method has little probability of causing seed gene mutation and high safety, and the method is easy to realize diversification of optimized varieties and put into production practice, so the method has great economic benefit and social benefit.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a far-field microwave breeding method. technical background [0002] The importance of food security to China, a country with a large population, is self-evident. Research on crop breeding technologies to increase crop yields and ensure the genetic safety of food to humans is a major topic in the field of agricultural science. [0003] At present, there are mainly five kinds of crop breeding techniques used in my country: hybridization, mutagenesis, haploid, polyploid, and genetic engineering. [0004] Hybridization technology is the method of continuous self-crossing and continuous selection to recombine the genes of crops to obtain optimized varieties. Its shortcoming is that the breeding period is long, and continuous selfing is required to continuously select the superior and eliminate the inferior to select the desired type. [0005] Mutation technology is the...
