Embodiment 1

[0026] The cultivation method of the early knot high yield of the northern pear tree of present embodiment comprises the following steps:

[0027] S1. After the leaves of the pear tree fall in autumn, cut the strong strips of the two-year-old pear tree mother plant that grows normally, has no pests and diseases, and has plump axillary buds as cuttings. There are 5-7 full buds on the cuttings, and the cuttings are buried. in wet sand;

[0028] S2. Select a field with a pH of 5.8-7, loose soil, and a soil salt content of ≤0.2% as a field for cuttings, dig 1 m deep, and then backfill with sawdust, sand and field soil, and add compound fertilizer and farmhouse to the backfill. One week before cutting, use 800 times chlorothalonil solution to sterilize the cutting bed, and fill the bottom water; add fertilizer to the backfill soil to ensure soil fertility, avoid the phenomenon of "fake death" when cuttings grow, and improve the survival rate of cuttings;

[0029] S3. In March of t...

Abstract

The invention provides a cultivation method for early-fruiting and high-yield pear trees in the north, and relates to the technical field of fruit tree cultivation. The cultivation method comprises the steps of selection and treatment of cuttings, management in the later period and treatment after the pear trees grow for 1-2 years. The cultivation method is scientific, the peer trees fruit early and are high in yield, most diseases and pests attacking the pear trees easily can be prevented, the morbidity of the pear trees in the later period can be reduced, the management in the later period is facilitated, and the losses caused by the diseases and the pests are reduced; pears finally produced by means of the cultivation method are good in taste, high in quality, beautiful in color and high in sweetness, and the pears contain abundant selenium and are beneficial to health.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a cultivation method for early fruiting and high yield of northern pear trees.
