Method for cultivating melon seedlings with high disease resistance and melon seedlings

Abstract

The invention discloses a method for cultivating melon seedlings with high disease resistance and the melon seedlings. The method comprises the following steps: (1) treating melon seeds with an alternating magnetic field; (2) sterilizing a seedling substrate and then mixing the substrate with a mixed solution containing beneficial microorganisms for use; (3) sowing; (4) pre-emergence cultivation and observation of emergence rate; (5) post-emergence cultivation: cultivating the seedlings in a solar greenhouse when the number of the seedlings reaches a certain amount, selecting different cultivation conditions during the day and the night, spraying a solution containing lilacinin to the leaf surfaces and watering the roots when a certain amount of the melon seedlings grow at least 2 true leaves; transplanting when the melon seedlings grow at least 4 true leaves to cultivate the melon seedlings with the high disease resistance. The melon seedlings cultivated by the above method are also provided. According to the method, the germination rate of the melon seeds can be effectively improved, and the disease resistance of the melon seedlings is improved.

Description

technical field [0001] The invention belongs to the technical field of melon cultivation, and in particular relates to a method for cultivating melon seedlings with high disease resistance and the melon seedlings. Background technique [0002] Melon (Cucumis melo L.), also known as muskmelon, fruit melon, sweet melon, ripe melon, is an annual vine herb of Cucurbitaceae; muskmelon is the earliest melon used as a fruit in my country, and it is widely planted in various parts of our country. Common muskmelon, Hami melon , Bailan melon, etc. belong to different strains of melons. Melon contains a lot of carbohydrates, citric acid, carotene, B vitamins, and vitamin C. It is one of the important fruits. However, in the process of planting melons, they are susceptible to various diseases, which lead to a reduction in the production of melons, and in severe cases, even lead to a failure of the harvest. [0003] And in the planting process of muskmelon, the condition of seedling gro...

AI Technical Summary

Problems solved by technology

However, in the process of planting melons, they are susceptible to a variety of diseases, which will lead to a reduction in the production of melons, and even lead to failure in severe cases.

[0003] And in the planting process of muskmelon, the condition of seedling growth is the key to whether there is strong disease resistance in the later stage, so there are many improvement schemes for the cultivation of muskmelon seedlings in the prior art, such as Chinese invention patent CN106665055A, which discloses A method for cultivating reticulated muskmelon seedlings resistant to continuous cropping obstacles is developed. The specific technology used is to use continuous inoculation (pathogenic bacteria) to cultivate resistant seedlings at the seedling stage of melons. This technical method has relatively high requirements for technical operators. High, and it takes a long time, which is not conducive to promotion and use;

[0004] Another example is the Chinese invention patent CN105230310A, which discloses a production method of high-quality melon seedlings. The specific technology used is grafting technology, and the pumpkin seedlings are used as rootstocks to carry out the grafting of melon seedlings. This is also a requirement for operators. High, and there is the possibility of changing the taste of melon, which is not conducive to large-scale application;

[0005] Another example is the Chinese invention patent CN106665047A, which discloses a method for cultivating muskmelon in greenhouses, wherein the nutrient solution used contains extracts of honeysuckle, Achyranthes bidentata, Sophora flavescens, phoenix leaves, Tripterygium wilfordii, Houttuynia cordata, Buddleja, It not only provides nutrients for the growth of melon, but also has the function of sterilizing and killing insects to reduce the occurrence of diseases; at the same time, it is added with chlorobromoisocyanuric acid, chlorothalonil, and mandipropamid, which can kill harmful pests; for the breeding stage The method technology is to adopt conventional crop cultivation technology, and the cultivation cost is too high at the same time, and there is no targeted improvement to melon breeding
