Anti-cold inducing agent for vegetables and using method thereof

Abstract

The invention relates to an anti-cold inducing agent for vegetables and a using method thereof. The anti-cold inducing agent contains calcium chloride (CaCl2) 10mmol.L-1, magnesium chloride (MgCl2) 3mmol.L-1, abscisic acid (ABA) 0.1mmol.L-1, and the balance water for constant volume. The anti-cold inducing agent is suitable for winter and spring seedling raising or sunlight greenhouse cultivation of thermophilic vegetable crops such as cucumbers and tomatoes. The using time arrangements include that the anti-cold inducing agent is used for seedling raising between November each year and February next year and sprayed when each seedling has two leaves and one core to three leaves and one core, spraying is performed each day and carried out for two continuous days, or the anti-cold inducing agent is used in 3 days prior to cold current after field planting to February next year, and the anti-cold inducing agent is used for once at an interval of 20-30 days and is used for 2-3 times in total. Reagents used by the anti-cold inducing agent are plant hormone and plenty of elements necessary for growth of the vegetables, the costs are low, pollution is avoided, not only is cold resistance of the cucumbers remarkably improved, but also mineral content of the cucumbers can be improved, and product nutrition quality is improved.

Description

1) Technical field [0001] The invention relates to a vegetable anti-cold inducer and a using method thereof, belonging to the technical field of facility vegetable cultivation. (2) Background technology [0002] The solar greenhouse is the main facility for vegetable production in northern my country. Due to the relatively simple structure and low degree of environmental controllability, the room is often in low temperature and low light or sub-optimal temperature and light environment in winter and spring, which leads to physiological metabolic processes such as photosynthesis of vegetables in the facility. Inhibited, poor growth, yield and variety decline, further promote the occurrence of diseases and insect pests, and become an important limiting factor affecting the sustainable development of vegetables. Improving or inducing resistance is considered to be an important strategy and way to reduce the damage caused by adversity. In recent years, research on the mechanis...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to develop a vegetable for the problems of low temperature adversity often encountered in the current solar greenhouse vegetable production, resulting in slow growth, inhibited photosynthesis, and reduced yield and quality. Anti-cold inducer and its application method provide safe and effective cultivation measures for alleviating low temperature adversity barriers
