Pollution-free eggplant seedling raising and cultivating method in greenhouse in northern cold areas

Abstract

The invention discloses a pollution-free seedling raising and cultivating method for eggplants in a greenhouse in a northern cold region, and the seedling raising and cultivating method specifically comprises the following steps: selecting a vegetable field, building a plastic greenhouse, selecting seeds and accelerating germination, sowing, separating seedlings, field planting, managing after field planting and the like. The eggplant grafting excellent rootstock selected in seed selection and germination accelerating step is Solanum torvum seeds. The method for accelerating germination of theSolanum torvum seeds comprises the following steps: firstly, preparing 200ml of 200ppm gibberellin solution; then, soaking the Solanum torvum seeds with gibberellin; and finally, carrying out variable-temperature germination acceleration on the Solanum torvum seeds, rinsing the seeds with clear water every day in the variable-temperature germination acceleration process, and rinsing the seeds every day can effectively prevent the seeds from mildewing and breeding bacteria. The method focuses on improvement of a Solanum torvum germination accelerating method and temperature control, the germination accelerating method is simpler than that in the prior art, only gibberellin is used during germination accelerating, seeds are soaked in a gibberellin solution with the concentration of 200 ppmand subjected to variable temperature treatment, the germination rate can reach 80% or above, and the germination accelerating effect is good.

Description

technical field [0001] The invention belongs to the technical field of vegetable cultivation methods, and in particular relates to a pollution-free eggplant seedling cultivation and cultivation method in a greenhouse in a cold northern region. Background technique [0002] Eggplant was first produced in India, and was introduced to China in the 4th and 5th centuries AD. The eggplant cultivated in the Southern and Northern Dynasties was round, similar to the wild shape. In the Yuan Dynasty, long-shaped eggplants were cultivated, and by the end of the Qing Dynasty, this long-shaped eggplant was introduced to Japan. Eggplant has a straight root system with a root depth of 50 cm and a lateral extension of 120 cm, most of which are in the 30 cm cultivation layer. Eggplant is distributed all over the world and is widely planted in Asia, Africa, the Mediterranean coast, central and southern Europe, and Central America. Because in places such as Europe and the United States, it is...
