Nutrient solution for grafting of juicy peaches

Abstract

The invention discloses a nutrient solution for grafting of juicy peaches. The nutrient solution is prepared from components in parts by weight as follows: 8.2-18.6 parts of phytohormone, 20-40 partsof a fermentation broth, 0.001-0.004 parts of sodium molybdate, 0.4-1.5 parts of iron chelate, 1-4 parts of citric acid and 2-4 parts of activated carbon. The nutrient solution has the benefits as follows: the nutrient solution can effectively improve the content and activity of L-phenylalanine ammonialyase at combination parts of stocks and scions so as to improve the affinity of the stocks and the scions and increase the grafting success rate. After the nutrient solution is used for a period, the activity of NR in scion cells is increased, the absorption capacity for NO3<->-N is enhanced, conversion metabolism of NH4<+>-N is quick, accumulation of NH4<+>-N is reduced, meanwhile, the content and expression of soluble sugar, proline and soluble protein in scions can be improved, the osmotic conditioning capacity of the scions can be enhanced, and the salt tolerance is improved remarkably.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a nutrient solution for peach grafting. 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 plant ...

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
