Problems solved by technology

Once the symptoms of root cancer appear on the surface of the plant, it proves that the Agrobacterium T-DNA has been transferred to the chromosome of the plant, and the use of fungicides to kill the bacterial cells can no longer inhibit the proliferation of plant cells, let alone make the tumor symptoms disappear

Embodiment 1

[0020] A method for preventing root cancer of stone fruit seedlings. The raw materials are clay powder and 50% thiram wettable powder. The treated seedlings are 1-year-old peach tree grafted seedlings; the first step is to take the clay and dry it, crush it, and pass through a 50-mesh sieve , the disinfection treatment is to adopt exposure to the sun for 2 to 3 days to sterilize, cover with plastic film for 7 days, and then dry for 3 days for subsequent use; the second step is to prepare a drug solution, and the name of the drug is: thiram (English common name Thiram) 50% wettable powder preparation 200-400 times the solution (1 part of medicine plus 200-400 parts of water); the third step, the preparation of drug mud, the operation method is as follows: add 450ml of the prepared drug solution in proportion to every 1000g of clay powder, and keep stirring until it becomes even and sticky It can be used for root treatment of seedlings; the fourth step is to wash the roots of 1-y...

Embodiment 2

[0022] A method for preventing root cancer of drupe seedlings. The raw materials are clay powder and 10% Bekon aqueous solution. The treated seedlings are 1-year-old apricot grafted seedlings; the first step is to take the clay to dry, crush, pass through a 50-mesh sieve, and sterilize The treatment is to use 100 times of 40% formaldehyde solution to spray and disinfect, cover with plastic film for 7 days, and then dry it for 3 days for later use; the second step is to prepare the drug solution. Alkylmethylbenzyl ammonium chloride; when used, Bikang is prepared as a 400-600 times solution (1 part of drug plus 400 to 600 parts of water); the third step is the preparation of drug mud, the operation method is as follows: according to the clay per 1000g Add 450ml of the drug solution prepared in proportion to the powder, and continue to stir until it is uniform and sticky, then it can be used for root treatment of seedlings; the fourth step is to wash the roots of 1-2 year old apri...

Embodiment 3

[0024] A method for preventing root cancer of stone fruit seedlings. The raw materials are clay powder and chitosan oligosaccharide citrate callus 2% aqueous solution, and the treated seedlings are 1-year-old apple grafted seedlings; the first step is to take the clay to dry and crush , pass through a 50-mesh sieve, expose to the sun for 2-3 days to sterilize, cover with plastic film for 7 days, and then dry for 3 days before use; the second step is to prepare a drug solution. The name of the drug is: chitosan oligosaccharide citrate healing agent 2% water (The main ingredients are chitosan oligosaccharide citrate, carboxymethyl chitosan, free iodine, etc.). Chitosan oligosaccharide citrate callus is prepared as 200 times solution (1 part of medicine adds 200 parts of water) during use; The 3rd step, medicine mud preparation, operation method is as follows: according to every 1000g clay powder adds 450ml to prepare in proportion Keep stirring the drug solution until it becomes...

Abstract

The invention provides a method for preventing stone-fruit seedling crown gall, comprising the following steps: firstly, clay is taken, dried, crushed and filtered through 50-mesh sieve, and the filtered clay powders are disinfected and covered by plastic membrane for 7 days, and then sunned for 3 days; secondly, 200-700 times-diluted medical solution is prepared; thirdly, 450ml of medical solution which is prepared based on proportion is added into every 1000g of clay powders and then the mixture is continuously stirred until the mixture is evenly sticky and becomes medical mud used for treating the seedling roots; and fourthly, the seedling roots are treated, namely, the healthy nursery stock roots are washed with clean water, then dipped in the medical mud and uniformly enwrapped by the mud, followed by temporary planting and permanent planting. The method is simple and effective, and is suitable for large-scale promotion and application; the application of the method can protect the healthy stone-fruit seedlings permanently transplanted after 1-2 years from crown gall.

Description

Technical field: [0001] The invention relates to a method for preventing root cancer of stone fruit seedlings, in particular to a method for treating seedling roots when transplanting healthy annual peaches, apricots, plums, apricots and plums, apples, pears and other seedlings. It is suitable for 1 year after planting of seedlings - Free from root cancer for 2 years. Background technique: [0002] Plant root cancer, also known as crown gall, root cancer, etc., is a worldwide disease caused by Agrobacterium tumefaciens (Agrobactium tumefaciens), and its parasitic range is very wide. According to statistics, in addition to infecting main drupe fruit trees such as peaches, plums, apricots, cherries, pears, and apples, it can also harm 1,193 species of plants in 138 families such as grapes, jujubes, papayas, chestnuts, and walnuts. Among stone fruit trees, peaches, almonds, apricots, plums, cherries, and apricot-plum interspecific hybrids are the most susceptible hosts in frui...
