Problems solved by technology

[0003] Potatoes are widely planted in my country, but a variety of diseases will appear during the planting process. Among them, late blight has a high incidence rate and is caused by Phytophthora infestans. It is a devastating fungal disease that causes the death of potato stems and leaves and tuber rot. At present, Potato late blight is controlled by spraying a large amount of pesticides, which is likely to cause pesticide residues, reduce the yield and quality of potatoes, and cause great harm to the health of consumers

Embodiment 1

[0017] A method for preventing and treating potato late blight, comprising the following steps:

[0018] (1) Cut into pieces to accelerate germination: Choose potatoes with good growth, high yield, and strong disease resistance, wash them, cut into pieces, soak the potato pieces in an anthocyanin solution with a mass concentration of 0.04%, and soak for 20 minutes to prevent oxidation. Inhibit the activity of dormant hormones, provide nutrients, take them out, cover them with moist sand to accelerate germination, eliminate ungerminated and unhealthy potato pieces, and get germinated potatoes;

[0019] (2) Seedling hardening and cultivation: Put the germinated potatoes in the seedling hardening room, and harden the seedlings for 36 hours. During this period, irradiate with ultraviolet light for 10 minutes every hour, and wait for the potato pieces to be planted;

[0020] (3) Planting and cultivation: Put the potato pieces to be planted in the planting pot, cover with 3~4cm of s...

Embodiment 2

[0028] A method for preventing and treating potato late blight, comprising the following steps:

[0029] (1) Cut into pieces to accelerate germination: Choose potatoes with good growth, high yield, and strong disease resistance, wash them, cut into pieces, soak the potato pieces in an anthocyanin solution with a mass concentration of 0.05%, and soak for 23 minutes to prevent oxidation. Inhibit the activity of dormant hormones, provide nutrients, take them out, cover them with moist sand to accelerate germination, eliminate ungerminated and unhealthy potato pieces, and get germinated potatoes;

[0030] (2) Seedling hardening and cultivation: put germinated potatoes in the seedling hardening room, and harden the seedlings for 36 hours. During this period, they are irradiated with ultraviolet rays for 13 minutes every hour, and the potato pieces are waiting to be planted;

[0031] (3) Planting and cultivation: Put the potato pieces to be planted in a planting pot, cover with a st...

Embodiment 3

[0039] A method for preventing and treating potato late blight, comprising the following steps:

[0040] (1) Cut into pieces to accelerate germination: Choose potatoes with good growth, high yield, and strong disease resistance, wash them, cut into pieces, soak the potato pieces in anthocyanin solution with a mass concentration of 0.06%, soak for 25 minutes, anti-oxidation, Inhibit the activity of dormant hormones, provide nutrients, take them out, cover them with moist sand to accelerate germination, eliminate ungerminated and unhealthy potato pieces, and get germinated potatoes;

[0041] (2) Seedling hardening and cultivation: put germinated potatoes in the hardening room, harden the seedlings for 36 hours, and during this period, irradiate with ultraviolet light for 15 minutes every hour, and wait for the potato pieces to be planted;

[0042] (3) Planting and cultivation: Put the potato pieces to be planted in a planting pot, cover with a sterilized substrate of 3~4cm, keep...

Abstract

The invention mainly relates to the technical field of planting, and discloses a method for preventing and treating potato late blight. The method comprises the steps of slicing and germination accelerating, seedling hardening cultivation, planting and cultivation and insect killing and bacterium killing. The method is simple and efficient, an anthocyanin solution is added for soaking during germination accelerating, oxidization resistance is achieved, nutrition and resistance are improved, and the germination accelerating rate reaches 97%. Environmental conditions are gradually changed during seedling hardening, seedling hardening is accelerated, environmental suitability is enhanced, and the seedling hardening survival rate reaches 94%. A sterilized matrix is used for soilless culture, the environment is beautiful, unified management is promoted, late blight bacteria are prevented and treated, and the cultivation survival rate reaches 98%. A traditional Chinese medicine disease resisting agent is used for regular spraying in the whole growth process of potatoes, occurrence and reproduction of the late blight bacteria are inhibited, the morbidity of the late blight is reduced to 3% or below, and the economic income of farmers is increased by 16.8%.

Description

technical field [0001] The invention mainly relates to the technical field of planting, in particular to a method for preventing and treating late blight of potatoes. Background technique [0002] Potatoes are one of people's favorite vegetables. They are rich in carbohydrates, dietary fiber, protein, vitamins and mineral elements. They can be used as a staple food to supplement nutrition, nourish the stomach and strengthen the spleen, promote gastrointestinal function, lower blood sugar and lipids, beautify the skin, and diuresis Reduce swelling, lose weight. [0003] Potatoes are widely planted in my country, but a variety of diseases will appear during the planting process. Among them, late blight has a high incidence rate and is caused by Phytophthora infestans. It is a devastating fungal disease that causes the death of potato stems and leaves and tuber rot. At present, Potato late blight is prevented and controlled by spraying a large amount of pesticides, which is lik...
