Problems solved by technology

Soft-seed pomegranate root rot mostly occurs in annual seedlings, and a few are perennial saplings. The occurrence period is the hot and humid rainy season from May to September. Poor drainage and poor soil air permeability often limit the range of activities of pomegranate tree roots and the ability to abs

Example Embodiment

[0019] Example 1

[0020] This embodiment provides a method for preventing soft seed pomegranate root rot, including the following steps:

[0021] 1) Choose plots with good soil permeability and drainage as nursery plots or planting plots, dig a planting ditch with a width and depth of 80cm×80cm or a planting pond with a width, depth and length of 80cm×80cm×80cm, and remove the subsoil and topsoil Stack them separately, and then spread crop stalks (corn stalks or pine needles) with a thickness of 30-40cm on the bottom layer, backfill to 2 / 3 of the depth of the ditch, and then evenly apply 1840 kg / mu of organic fertilizer, and the phoxim addition amount is 1.84 kg / The dosage of carbendazim is 0.92 kg / mu. The topsoil is backfilled in the ditch, and finally the soil is backfilled to 40-50cm above the ground, and it is filled with water and rammed for planting.

[0022] Ridging cultivation can effectively increase the soil thickness of the pomegranate orchard, increase the soil moistu...

Example Embodiment

[0026] Example 2

[0027] Experiment site 1: Qingyi Village, Qingna Town, Yongsheng County.

[0028] Planting time: February 2017.

[0029] Cultivated varieties: two-year-old soft-seed pomegranate cuttings.

[0030] Planting area and quantity: 26 acres of 2,400 plants.

[0031] Measurement time: December 2, 2019.

[0032] Planting and management process:

[0033] In January 2017, dig a planting trench with a width and a depth of 80cm×80cm or a planting pond with a width, depth and length of 80cm×80cm×80cm on the planting plot, stack the subsoil and topsoil separately, and backfill the soil to 2 / 3 of the depth of the trench , And then evenly apply 1840 kg / mu of organic fertilizer, add phoxim at 1.84 kg / mu, and add carbendazim at 0.92 kg / mu. The mixed topsoil is backfilled in the ditch, and tamped with water for planting.

[0034] In February 2017, two-year cutting seedlings were planted in the prepared planting ditch or planting pond with a row spacing of 2.5 meters X 3 meters. The wateri...

Abstract

The invention discloses a method for preventing soft-seed pomegranates from suffering from root rot. The method comprises the steps of selecting planting land parcels, digging field planting trenchesor planting ponds, paving crop stalks at the bottoms of the field planting trenches or the planting ponds, performing backfilling to 2/3 of the depth of the trenches, applying a fertilizer, continuingperforming backfilling, performing ridging, planting grafting seedlings in the prepared field planting trenches or the planting ponds, and performing annular fertilizing in autumn and winter each year. The proportion of the soft-seed pomegranates cultured by the method disclosed by the invention suffering from the root rot is only 0.07%, and the root rot of the soft-seed pomegranates can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for preventing root rot of soft-seed pomegranate. Background technique [0002] Root rot is a disease caused by a fungus. This disease will cause the roots to rot, the function of absorbing water and nutrients will gradually weaken, and finally the whole plant will die, mainly manifested as yellowing and withering of the leaves of the whole plant. Soft seed pomegranate root rot occurs in major pomegranate producing areas in my country. At the initial stage of the disease, white hyphae appear in the rhizosphere, and when the disease progresses to a later stage, the whole root rots, the leaves wither from bottom to top, and the plant withers, eventually leading to the death of the whole plant, which has a great impact on pomegranate production. [0003] Pomegranate trees in my country are mostly planted in mountainous and hilly areas. No matter w...
