Fruit tree rotation device and liberobacter asiaticum control and repairing process

Abstract

The invention discloses a fruit tree rotation device and a liberobacter asiaticum control and repairing process. By means of the process, through rotation management for fruit trees, the immune function of the fruit trees is greatly improved, so that citruses or other fruit trees are not easily infected with liberobacter asiaticum, canker, root rot or the like; the citruses with liberobacter asiaticum which are sprayed with antibiotics to eliminate the degradability of endophytes can be prevented from being re-infected, the repairing effect on the citruses with liberobacter asiaticum is achieved, meanwhile, the repairing effect on the root rot of other fruit trees is also achieved, and the worldwide problem that liberobacter asiaticum and fruit tree root rot cannot be radically treated iseffectively solved; meanwhile, the use amount of chemical fertilizer is reduced, the fertilizer efficiency is improved, the use of a large amount of pesticide for control and treatment is avoided, thepollution of the chemical fertilizer and pesticide to the environment is reduced, the yield of the fruit trees is increased, the fruit quality of the fruit trees is improved, and the economic incomeof fruit farmers is increased.

Description

Technical field: [0001] The invention relates to a fruit tree rotation device and a technique for preventing, controlling and repairing Huanglong disease, belonging to the technical field of agricultural cultivation. Background technique: [0002] The root diseases of fruit trees are difficult to prevent and control, the tree age and fruit-bearing period are short, the pesticide residues are high and the fruit is low are the difficulties that the fruit industry cannot get rid of. Especially like the yellow dragon disease of citrus, the research data of yellow dragon disease at home and abroad for more than 100 years shows that there is no curative medicine or effective control strategy, and the existing research ideas have no radical effect on the yellow dragon disease. It has been discovered that Huanglongbing is a bacterial disease caused by a plant-derived bacteria that can block the function of the phloem. Once infected with this bacteria, the nutrients produced by the leave...

Problems solved by technology

During the research process, the present invention, through a large amount of crop rotation, continuous cropping and fallow research references, combined with the comparative analysis of wild fruit tree soil, orchard soil and abandoned land soil, found that the degrading bacteria produced by the residual roots of this species in the previous year (abbreviated as This degrading bacteria) has enzymatic hydrolysis and cell phagocytosis damage to the newly planted roots of this species, and has no damage to the roots of foreign species. There must be no damage; if a single variety is planted for many years, the native bacteria in the soil will not be consumed by foreign species and will flood, causing damage to the root system. After the root system is damaged, it needs to consume nutrients to repair and regenerate. Fruit trees absorb After a large number of decomposing bacteria, the endophytic bacteria structure still retains the degradability, which has the effect of enzymolysis and cell phagocytosis on the fruit tree cell tissue, destroying the transport function of amino acids and sugars of the fruit tree, resulting in the lack of nutrition of the fruit tree and starting to get sick. Antibiotics The injection can eliminate the degradability of the endophytic bacteria in fruit trees. The symptoms of huanglongbing disappear within the antibiotic's limitation period, the amino acid and sugar transmission function of the fruit tree recovers, and the fruit can mature normally; after the antibiotic's limitation period, Under the condition of continuing to absorb the bacteria of this solution, the symptoms of Huanglongbing disease will be restored, and the transmission function of amino acids and sugars of the fruit tree will be lost, and it will not be able to provide nutrients for fruit growth and maturity.

This problem can be solved by using crop rotation for annual crops. Fruit trees are perennial species and belong to continuous cropping species. The existing traditional fruit tree production cannot be solved by crop rotation.
