Dwarf interstock apple tree deep-pit shallow-planting method in dry land

Abstract

The invention belongs to the technical field of fruit tree cultivating, and discloses a dwarf interstock apple tree deep-pit shallow-planting method in dry land. According to the method, the nursery stock planting depth is 4/5 of the buried depth of dwarf interstocks, and the dwarf stocks are exposed for 5 cm; according to the soil sinking degree of field-planting furrows, stocks are reserved to be sunken for 2-3 cm; when the dwarf stocks are exposed, the upper portions are taken care of, the lower portions are left aside, and the upper portions of the dwarf stocks are exposed uniformly and located on the same horizontal line; rooting of the dwarf interstocks is put off for one year, in the first year, original stocks are utilized for improving the tree vigor, and in the next spring, required parts are backfilled with soil. According to the method, the nursery stocks and a nursery field are kept consistent in growth, after field planting, the temperature of the soil is close to that onthe ground, the growth is coordinated, and the serious problem of a traditional deep planting method that moisture and nutrition at the upper and lower portions are imbalanced is solved; large pan-bottom-shaped pits formed under trees help to collect rainwater, thin film is adopted for coverage so that moisture can come into the pits but cannot exit from the pits, evaporation is reduced, so thatsaplings are irrigated multiple times, the problem that the loess plateau is lack of water and suffers from drought is solved, and the utilization rate of the moisture is increased.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, in particular to a method for deep pit and shallow planting of dwarfed middle stock apple trees in dry land. It is a technological innovation for cultivating dwarf middle stock apples in the dry land of the Loess Plateau. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Due to the mechanism of dwarfing, dwarfing fruit trees have thick leaves, high chlorophyll content, strong light energy utilization rate, high dry matter accumulation, and the light enhancement is 3-5 times that of arborized trees. The vegetative growth of the tree is easy to transform into reproductive growth, with few long branches and a large amount of short branches, so it is easy to flower and bear fruit earlier, generally 3-4 years earlier than arborization trees, and the return on investment in the orchard is fast and the economic bene...

AI Technical Summary

Problems solved by technology

[0015] The difficulty lies in: dwarf apples are planted abroad with dwarf self-root stock, and there is no cultivation experience abroad for dwarf intermediate stock, especially in the dry land of the Loess Plateau in Northwest China. , many successful experiences in dryland cultivation have been obtained through experimental research and demonstration, but the technical problem of how to solve the system with dwarfing intermediate stock still exists
