What are the precautions for using pear fruit swelling agent?
Pear fruit swelling agent is a plant growth regulator developed and utilized in recent years. Its effect is to promote fruit cell enlargement, especially when used on early and mid-season pears, where the swelling effect is obvious.
However, improper use of pear fruit swelling agent will not only fail to achieve the ideal effect, but also cause side effects. Therefore, for pear trees using swelling agent, water and fertilizer must be kept up, especially full-element chemical fertilizers, to ensure sufficient nutrients to meet the needs of fruit growth and development, so as to achieve the ideal effect.
In addition, harvest at the right time. Although swelling agent has the effect of promoting ripening, it can only advance ripening by 7-10 days. If harvested too early, even if the fruit weight reaches its inherent weight, it has not reached the proper ripening stage, which will cause the flavor to become bland and the quality to decline. However, harvesting too late is even more harmful, as over-ripening will reduce storage tolerance. Therefore, the suitable harvest period for fruit using swelling agent should be about 7-10 days earlier.
