Nutrient solution for pear tree grafting

Abstract

The invention discloses a nutrient solution for pear tree grafting. The nutrient solution is prepared from, by weight, 8.2-18.6 parts of auxin, 20-40 parts of fermentation broth, 0.001-0.004 part of sodium molybdate, 0.4-1.5 parts of chelate iron, 1-4 parts of citric acid and 2-4 parts of activated carbon. The nutrient solution has the advantages that the nutrient solution can effectively increasethe content of L-phenylalanine ammonia lyase of the joint part of a stock and a scion and improve the activity of the L-phenylalanine ammonia lyase of the joint part of the stock and the scion, the compatibility of the stock and the scion is improved, and the grafting success rate is increased. After the nutrient solution is used for a period of time, the NR activity in scion cells is improved, the absorption capacity to NO3<->-N is enhanced, NH4<+>-N transformation and metabolism are fast, accumulation of NH4<+>-N is reduced, and meanwhile the scion soluble sugar, proline, soluble protein content and expression can be increased, the osmotic conditioning capacity of the scion is enhanced, and the salt tolerance is obviously improved.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a nutrient solution for grafting pear trees. Background technique [0002] Grafting technology has promoted the development of agriculture and forestry, especially the difficult problem of seedling rooting in forestry production, which has become one of the major problems restricting the development of forestry. Using the root system of the rootstock through grafting technology not only solves this problem, improves the survival rate and the ability to resist adversity, but also makes the scion grow rapidly, and may even produce the desired variation type, which can be said to serve multiple purposes. At present, grafting technology has developed from traditional branch and bud grafting to bud seedling grafting, and micro-grafting has been formed by organically combining tissue culture and grafting technology. Its application fields are constantly expanding, not only for expanding p...

Problems solved by technology

[0003] In recent years, although there have been a small amount of wound repair fluids on the market, in practice, there are still certain limitations, which cannot meet the needs of a large number of grafts, and there are problems of low survival rate and low utilization efficiency after grafting, and cannot be fully utilized. The role of large-area applications, especially the grafting of wood and flowers cannot meet the needs of use
