Embodiment Construction

[0030] Below in conjunction with embodiment (test site is Xiangyin County, Yueyang City, Hunan Province, field is dry soil, adopts greenhouse to grow seedlings, transplant), the present invention will be further described. The following description is by way of example, but the protection scope of the present invention should not be limited thereto.

[0031] The method for the bactericidal, antiviral and pest-proof of the selenium-enriched Jerusalem artichoke propagation and its cultivation stage of the present embodiment, its cultivation process is as follows:

[0032] (1) Selection:

[0033] When harvesting in autumn and winter, choose Jerusalem artichoke tubers with a weight of 19-26 grams, no insect disease, and a complete shape, and divide them into small and large according to the two standards of 19-22 grams and 23-26 grams;

[0034] (2) Sterilization, disinfection and maintenance of seed blocks:

[0035] ① Sterilization, disinfection, and maintenance after harvesting...

Abstract

The invention discloses a method for reproduction, cultivation and disease resistance and pest prevention of selenium-enriched Helianthus tuberosus, and relates to the technical field of planting of asteraceae, taccaceae and helianthaceae (Helianthus tuberosus). The method comprises the cultivation process of: (1) selection of seeds; (2) sterilization, disinfection and maintenance of the block seeds: a, performing sterilization, disinfection and maintenance after harvest and before seed storage; and b, performing sterilization, disinfection and maintenance before sowing; (3) preparation of a field: a, performing soil disinfection; b, performing pit digging or ditching; c, preparing selenium-enriched fertilizer; and d, applying the selenium-enriched fertilizer; (4) cultivation, transplanting or direct sowing and seeding of selenium-enriched Helianthus tuberosus seedlings: a, performing seedling cultivation and transplanting in a greenhouse; and b, performing direct sowing, pit plantingand ditch planting; and (5) field management. The cultivated Helianthus tuberosus has less pests and diseases during the whole growth process, the yield of Helianthus tuberosus per mu is improved significantly, and the cultivated Helianthus tuberosus is rich in organic selenium, can be used as a raw material for selenium-enriched health food, so that the nutritional value and economic value of theHelianthus tuberosus are improved.

Description

technical field [0001] The present invention relates to a kind of agricultural crops of Compositae, Dioscoreae and Sunflower: Selenium-enriched Jerusalem artichoke breeding, sterilization, disinfection and maintenance in the process of cultivation and rich in organic selenium, anti-virus (green dwarf disease, yellow leaf disease), Methods of preventing pests (bud bugs, mole crickets). Background technique [0002] Jerusalem artichoke, scientific name Helianthus tuberosus, also known as sunflower ginger, crispy ginger, five-star grass, etc., is a perennial herbaceous plant in the family Compositae and Dioscoreaceae, with a height of 1 to 2.5 meters. It has tubers and erect stems. Stems with many branches and leaves, yellow flowers. Jerusalem artichoke is native to North America and introduced to China via Europe. Now it is cultivated in most parts of China. The underground tubers are rich in fructose polymers such as starch and inulin. It is a good food and medicine homologo...
