Problems solved by technology

However, so far, although agricultural experts in my country and other countries in the world have carried out various experiments and achieved some results, they still cannot make food crops like soybeans, alfalfa and other plants to naturally grow nodules, fix nitrogen and make fertilizer for food production.

Embodiment Construction

[0014] The concrete implementation of the present invention is as follows:

[0015] 1. Selection of rootstock and scion:

[0016] The rootstock should be a hybrid sunflower or corn with high plasticity.

[0017] Scions should be selected from soybean varieties with high nitrogen fixation activity and stable heredity in leguminous plants.

[0018] 2. Grafting method:

[0019] Grafting must be carried out at the time when seedling cell division is the most active, and metabolism, nutrients and genetic information exchange are the most vigorous. At this time, callus is also likely to be produced at the interface, and the ear and the anvil are integrated.

[0020] Grafting will be carried out when rootstock grows 1-6 leaves, and now the immunity of stock is the weakest, and scion can exert maximum influence on stock; scion also will carry out when growing 1-6 leaves. Grafting adopts split grafting. Use a single-sided blade to cut a 1.2-2CM incision vertically downward at the mi...

Abstract

The invention relates to a nodule bacteria transferring method by utilizing distant grafting, comprising: 1) hybrid sunflowers and corns which have high plasticity are chosen as stock; 2) varieties with high nitrogen fixation activity and stable hereditary are chosen from leguminous plants; 3) cleft grafting is adopted, when 1-6 pieces of leaves of the stock grow and 1-6 pieces of leaves of the scion grow, grafting is carried out; 4) after the grafting survival is realized, the growth amount of the stock and the scion is rationally controlled; the plants with nodule bacteria and the plants without nodule bacteria are grafted by utilizing the distant grafting, so as to lead the nodule bacteria to be transferred to the plants without nodule bacteria and cause the plant without nodule bacteria to have nodule bacteria naturally.

Description

Technical field: [0001] The invention relates to a grafting method in the field of crops, in particular to a method for transferring rhizobia by remote grafting. Background technique: [0002] For nearly 150 years, biologists have been paying attention to scientific research in the field of biological nitrogen fixation. Especially in the past century, due to the serious negative impact caused by the extensive use of artificial nitrogen fertilizers in agricultural production, it has attracted great attention from all over the world. Therefore, many countries have listed biological nitrogen fixation science as a frontier key research topic. People expect that various plants, especially agricultural and forestry plants closely related to human life such as food, fruits and vegetables, can also grow root nodules like legumes and have high efficiency. Nitrogen fixation can meet the needs of nitrogen and replace the use of chemical fertilizers. This has obvious effects on improvi...
