Embodiment 1

[0017] Pretreatment: select peat moss: vermiculite as a 2:1 culture medium to cultivate strong seedlings as strawberry seedlings, and then use 80% alcohol to soak and disinfect for 5-15s, 0.2-0.3% HgCl2 for 2-3min, 0.4-0.6 % Sodium hypochlorite disinfection for 2-3 minutes and then cleaned with sterile water;

[0018] Fumigation treatment: place the pretreated seedlings in a saturated water vapor environment at 35-43°C, and simultaneously introduce a mixture of trace amounts of methyl bromide and carbon dioxide for fumigation treatment for 5-10 minutes;

[0019] Vacuum treatment: place the seedlings obtained by the fumigation treatment in a pressure of 3-5kPa and a temperature of 20-25°C, and perform vacuum treatment for 20-24h.

Embodiment 2

[0021] Preferably, the saturated steam temperature of the fumigation treatment is 36°C, and the treatment time is 6 minutes.

Embodiment 3

[0023] Preferably, the volume ratio of methyl bromide to carbon dioxide is 3:2, and the concentration of methyl bromide is 15-19 g / m3.

Abstract

The invention discloses an insect damage prevention method for strawberry seedlings. The method comprises the steps of pre-processing, fumigation treatment, vacuum treatment and the like. The method is excellent in insect killing and detoxification effect and growing effect, and the processing damage and risk can be reasonably controlled; furthermore, moisture remaining in the seedlings by the fumigation treatment can be effectively removed through vacuum processing so as to further kill pests, and the seedlings can be beneficially stored after the moisture is removed, therefore the using flexibility of the seedlings can be improved.

Description

technical field [0001] The invention relates to the technical field of plant seedling cultivation and cultivation, in particular to a method for preventing diseases and insect pests of strawberry seedlings. Background technique [0002] Strawberry belongs to the Rosaceae Strawberry genus perennial herbaceous fruit tree. Because strawberry not only has high nutritional value, but also has high medicinal value, coupled with the unique sweet taste of strawberry, it ranks first in the production of small berries and is unique in the world. It is cultivated in most countries. And my country is the largest strawberry producing country in the world at present, and strawberry cultivation area and annual output all rank first in the world. As one of the main domestic fruits, it has huge market potential and economic and economic benefit prospects. Guarantee the basis for the healthy development of the strawberry industry. [0003] Strawberry usually takes at least two yea...
