Problems solved by technology

[0002] The propagation of existing turmeric (scientific name Dioscorea DIoscorea zIngIberensIs C.H.WrIgh) mainly relies on tuber propagation and seed propagation, and tuber propagation needs a large amount of species, easy degradation of germplasm, easy to carry germs and pests
At present, seeds are propagated and seedlings are mainly planted after germination in the greenhouse. The germination of the seed greenhouse requires the construction of a special germination room, which requires special personnel to take care of it and keep turning it. Poor temperature and water management will easily lead to burnt seeds and bad buds. Because new sprouts are fragile, when turning It is easy to break the buds. Due to the concern between the buds and the buds during sowing, it is not easy to sow evenly, and it will cause mechanical damage, broken buds and bad buds, and infection of germs
So far, there is no experimental research report on the impact of turmeric’s previous crop varieties on seedling cultivation. There is no basis for the selection of seedbed land, and it is impossible to select the standard selection of seedbed land. In production, there are random land use, improper treatment of seedbed soil, serious disease in seedbeds, and susceptible seedlings. The serious problem of high mortality rate and mortality rate; because the seedlings carry germs and pests in the nursery, after transplanting, the roots and tubers are easy to rot, and the plants suffer from diseases, resulting in high mortality and high disease susceptibility, and the widespread spread of diseases and insect pests, which brings great harm to production. to seriously damage
There are also reports of on-demand planting with turmeric seeds. This method is not standardized and cannot meet the requirements of large-scale production.

Embodiment 1

[0038] Choose 1 mu of sandy loam soil on the newly opened land from east to west, turn the ground, prepare the ground, and rake the ground in the first winter, build a 2m high greenhouse, open the compartment at 1.5m, and apply 50kg of compound fertilizer as the base fertilizer when the compartment surface is flat, and the compartment surface is fine. Sow seeds on February 25. Wash the seeds with newly drawn well water to remove the deflated seeds. Before sowing, turmeric seeds were soaked in 100ppm gibberellin + 500 times carbendazim + 1000 times thiophanate-methyl solution at constant temperature for 1 night (12h). The temperature of the solution was kept at 25-30°C. Add 10 times the amount of plant ash of seeds and mix well.

[0039] Spread 5cm thick new mix soil on the side of the car (new wasteland soil: sieved river sand is 1:1), level it, sow 6kg evenly, cover the new mix soil 2cm, use a sprayer to spray the car surface with fine mist, and use Bamboo slices are used t...

Embodiment 2

[0045] Choose 1 mu of Tianshui field with good drainage in the east-west direction. The previous stubble is rice and sandy soil. The previous winter, deep plowing, land preparation, removal of residual straw and roots, raking and leveling, build a 2m high greenhouse, open the box according to 1.5m, and organize the box Apply 50kg of compound fertilizer as the base fertilizer during the surface, the surface of the compartment is fine, and the seeds are sown on February 28. Take newly drawn well water to wash the seeds and remove the deflated seeds. Before sowing, turmeric seeds were soaked in 100ppm gibberellin + 500 times carbendazim + 1000 times thiophanate-methyl solution at constant temperature for 1 night (12h). The temperature of the solution was kept at 25-30°C. Add 10 times the amount of plant ash of seeds and mix well.

Abstract

The invention provides a method which is applied to direct sowing and seedling of yellow ginger seeds in large scale in a greenhouse. The method comprises the following steps of place selection for a nursery garden, pretreatment of seeds, uniform sowing in greenhouse surface after dividing the compartment, prophase management after seedling emergence, middle-later period management after seedlingemergence, transplanting after seedling emergence, and the like, wherein three scientific nutrient solution compounding are used in the management after seedling emergence and the transplanting afterseedling emergence, thus providing reasonable nutrition proportion for each growth stage of the seedling and ensuring various nutrition elements required by the growth of the seedling. The method hasthe advantages of reducing the amount of pesticide, easily and conveniently obtaining seedling, having high utilization ratio of fertilizer, few broken roots, little workload, quick growth after transplanting with soil and capability of continuously breeding for more than 3 years by replacement of seedbed substrate and treatment of soil, improving the using efficiency of the greenhouse and reducing the production cost.

Description
