Embodiment 1

[0019] (1) On June 30, 2017, "Ningfeng" strawberry stolon cutting seedlings were picked, and 2,000 plug seedlings were cut, and the routine management was carried out until August 15. On August 15, 1,500 trees with diseased insects were artificially inoculated by the leaf transfer method, and the remaining 500 trees were isolated in a safe area as a control.

[0020] (2) On August 22, the matrix of 1500 plug seedlings with diseased insects was poured with enough water before storage.

[0021] (3) On August 22, 1,500 plug seedlings with diseased insects were set for three different treatments. The treatment methods were: temperature 35°C, 55% CO 2 、35℃+55%CO 2 , each processing 500 trees. of which CO 2 The concentration is adjusted by the monitor CO 2 The generator controls the flow rate so that the warehouse CO 2 The treatment concentration stabilized at 55%. From 4:30 to 6:30 in the afternoon, move the seedlings with diseased insects into different warehouses for proces...

Embodiment 2

[0025] (1) On July 3, 2017, "Ningyu" strawberry stolon cutting seedlings were collected, and 1,500 plug seedlings were cut during the rainy season, and the routine management until August 16. Select 1200 plug seedlings of consistent growth test for subsequent use, and find that the plug seedlings of seedling age 45 days all have 2 leaves and 1 heart, and the root system is normal.

[0026] (2) On August 16, the matrix of 1500 plug seedlings was poured with sufficient water before storage.

[0027] (3) On August 16, set the warehouse temperature to 35°C and turn on the CO 2 generator, via CO 2 Monitor Regulate CO 2 generator flow rate so that the warehouse CO 2 The concentration stabilized at 55%. 600 plug seedlings will be moved into the warehouse between 4:30-6:30 in the afternoon, and moved out between 4:30-6:30 in the morning of the third day, and the CO will be closed on August 18. 2 Generator and temperature equipment, another 600 plug seedlings were routinely manage...

Abstract

The invention discloses a method for treating strawberry plug seedlings with nitrogen dioxide. The method comprises the steps that according to requirements of strawberry seedlings, the strawberry plug seedlings which each have two leaves and one core and have the seedling age of 45 days or longer are selected; preparation is made for treatment, wherein before treatment, a plug seedling matrix issufficiently watered; the strawberry seedlings are processed, wherein the plug seedlings are placed in a warehouse in the afternoon, the CO2 concentration of the warehouse is set to be 55+ / -5%, the temperature is set to be 35+ / -2 DEG C, sealed treatment is carried out for 36-40 hours, and the strawberry seedlings are transported out of the warehouse in the morning on the third day; management is carried out after treatment, wherein the management of water, fertilizer, light and plants refers to plug seedling conventional management. Through high-temperature high-concentration CO2 treatment, the damage and propagation of diseases, pests and mites are effectively controlled from the source of the seedlings, the quality of the seedlings is improved, and the production seedlings which are highin quality, healthy and free of diseases, insects and mites are obtained. The plug seedling planting field has no seedling recovery stage, the survival rate is 100%, and the labor cost is reduced; the fruit maturity consistency is good, fruits appear on the market 5-10 days earlier, and the economic benefits are greatly improved.

Description

technical field [0001] The invention relates to a method for treating strawberry seedlings with nitrogen dioxide, and belongs to the technical field of strawberry seedling breeding. Background technique [0002] Strawberry has a short production cycle, quick results, high and stable benefits, and is one of the advantageous industries of high-efficiency agriculture in my country. According to FAO statistics, in 2016, my country's planted area and output were 141,500 hectares and 3.8019 million tons, respectively, accounting for 35.21% and 41.70% of the world's planting area and output, ranking first in both the area and output in the world. [0003] Strawberry planting requires high technology and is a labor-intensive industry. Compared with other crops, not only the working time is long, but also the labor intensity is high. As the country enters an aging population society, there are fewer and fewer young and middle-aged laborers engaged in agricultural production, and str...
