Problems solved by technology

The selenium content of tomatoes bred by ordinary methods is low. In order to increase the selenium content of tomatoes, people increase the amount of selenium fertilizer applied during planting. Although good results have been achieved, long-term selenium fertilizer application not only increases the planting cost. , will cause excess nutrients and affect the composition of soil nutrients, and with the increase of time, the absorption effect of tomato plants on inorganic selenium will continue to decline, which is obviously not in line with the sustainable development of the planting model

Abstract

The invention discloses a cultivation method of a selenium-enriched tomato, and belongs to the technical field of planting. The cultivation method comprises the following steps: (1) seedling selection, (2) seedling modification, and (3) seedling planting and cultivation. Tomato seedlings cultivated by this method have strong absorptive capacity for selenium, selenium content in the final cultivated tomato is improved by more than two times, and the survival rate of tomato seedlings is improved, and the comprehensive planting efficiency is higher.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a method for cultivating selenium-enriched tomatoes. Background technique [0002] Tomatoes have become one of the indispensable vegetables in people's lives because of their rich nutritional value, sweet and sour taste and other advantages. Selenium is one of the 15 daily dietary nutrients. If the intake of selenium is insufficient, many diseases such as cardiovascular disease, Keshan disease, and Kaschin-Beck disease will occur. Therefore, people need to moderately increase the intake of selenium . The selenium content of tomatoes bred by ordinary methods is low. In order to increase the selenium content of tomatoes, people increase the amount of selenium fertilizer applied during planting. Although good results have been achieved, long-term selenium fertilizer application not only increases the planting cost. , will cause excess nutrients and affect the composit...
