Embodiment 1

[0047] A kind of GF677 peach rootstock mother plant field shading treatment provided by the preferred embodiment of the present invention, the method for cutting and rooting in the twig arch shed comprises the following steps:

[0048] S1, GF677 peach rootstock mother plant shade treatment in field

[0049] In spring, when the mother plant of GF677 peach rootstock is showing green buds, use pruning shears to cut off the branches of the mother plant that are more than 30 cm above the ground, and then water it thoroughly once, and no longer water before cutting the cuttings. Above the mother plant, build a one-meter-high arch shed with bamboo slices, and then use a shading net with a shading rate of 40% to shade the entire mother plant, and use soil compaction to fix the sun-shading net.

[0050] S2. Acquisition of shoots for cuttings

[0051] When the length of the shading-treated branches in (1) reaches 30 cm, cut off 10 cm at the base, and bring them back to the shed after m...

Abstract

The invention discloses a vegetative propagation method of GF677 peach rootstocks, and relates to the technical field of a propagation method of the peach rootstocks. The vegetative propagation methodof the GF677 peach rootstocks comprises the following steps of: carrying out shading treatment on a GF677 peach rootstock mother plant field; obtaining twigs for cottage; preparing and processing a cottage matrix; processing a growth regulator of the twigs for cottage and carrying out cottage; carrying out management after cottage; and carrying out seedling hardening on cutting seedlings. The scheme has the advantages of enabling the GF677 peach rootstocks to really play the advantages of high grafting compatibility, salinity and alkalinity resistance, drought avoidance, resistance to soil depletion, resistance to peach continuous cropping and the like of the GF677 peach rootstocks, breaking through the bottleneck of low rooting percentage of cutting propagation of the GF677 peach rootstocks, implementing rapid large-scale production of the cutting seedlings of the GF677 peach rootstocks, greatly reducing production cost and improving peach yield and quality.

Description

technical field [0001] The invention belongs to the technical field of propagation methods of peach rootstocks, and in particular relates to a method for asexual propagation of GF677 peach rootstocks. Background technique [0002] GF677 is a high-quality peach rootstock bred by the French Institute of Agricultural Sciences (Institut National de la Recherche Agronomique) in the 1960s from the hybrid offspring of peach and almond. Compared with traditional peach rootstocks in my country, such as peach and apricot, GF677 has the following obvious characteristics: 1. Strong grafting affinity, high yield and good quality of grafted varieties; 2. Strong salt tolerance, salt resistance Strong ability to iron deficiency chlorosis caused by alkaline soil; 3. Strong drought tolerance, resistance to poor soil; 4. Resistance to heavy peach cropping. Therefore, GF677, as one of the main rootstocks of peach trees, is widely used in Europe, especially Italy, France, Spain and other countri...
