The Method of Cultivating Strong Tomato Seedlings by Mixing Choline Chloride and Calcium Prohexadione

Abstract

The invention provides a method mixing choline chloride and prohexadione calcium to cultivate tomato strong seedlings. The method comprises the steps of evenly mixing grass carbon, vermiculite and perlite according to the volume ratio of 6:3:1 to be put into a seedling culturing tray, sowing seeds, then placing the seedling culturing tray into a seed bed to culture seedlings, placing the seedling culturing tray into functional liquid when two main leaves of the tomato seedlings completely spread, taking out the seedling culturing tray when the grass carbon is completely soaked, and placing the seedling culturing tray into the seed bed again to culture the seedlings. The functional liquid comprises 0.015%-0.03% of choline chloride, 0.03%-0.04% of prohexadione calcium and 0.5%-0.8% of boric acid, and the rest is water. In a seedling culturing process, not any plant growth regulating agent is sprayed and fertilized, the excessive growth of the tomato seedlings is controlled, and side effects caused by spraying and fertilizing general growth inhibitors are effectively avoided. In addition, cultured seedlings are better than existing general seedlings in the aspects of root activity, strong seedling indexes, planted yield and the like.

Description

technical field

[0001] The invention relates to a method for cultivating strong tomato seedlings by mixing choline chloride and prohexadione calcium, which belongs to the field of agricultural technology. Background technique

[0002] Tomato plug seedlings have been widely used in production. The traditional plug-in seedling raising technology is exactly to use peat, vermiculite, perlite and other lightweight materials as substrates, and plug-in trays with different holes as containers. Its characteristics are: one hole for one grain when sowing, one hole for one plant when seedlings grow, each seedling has an independent space, water and nutrients do not compete with each other, the age of seedlings is 10 to 20 days shorter than that of conventional seedlings, and the seedlings grow quickly , no soil-borne diseases, and the root lumps of seedlings are not easy to disperse, the root system is complete, the roots are not damaged after planting, the seedlings are slowed down ...
