Method for culturing sound seedlings of cucumbers

Abstract

The invention discloses a method for culturing sound seedlings of cucumbers. The method comprises the following steps of firstly dissolving prohexadione calcium in water so as to obtain a prohexadione calcium aqueous solution; then adding the prohexadione calcium aqueous solution into carbonized rice husks, and uniformly mixing the prohexadione calcium aqueous solution with the carbonized rice husks so as to obtain a prohexadione calcium and carbonized rich husk adsorbate; then uniformly mixing the prohexadione calcium and carbonized rice husk adsorbate with turf and vermiculite in a volume ratio of the prohexadione calcium and carbonized rich husk adsorbate to the turf to the vermiculite being 1 to 2 to 1, so as to obtain seedling culturing substrates; and culturing seedlings with the substrates so as to obtain seedlings of the right ages, namely the sound seedlings of the cucumbers. According to the method disclosed by the invention, the prohexadione calcium is prepared into the seedling culturing substrates in a manner of the carbonized rice husk adsorbate, so that the half life time of the prohexadione calcium is delayed by 7-8 days, the validity period of the prohexadione calcium is prolonged, and the cultured seedlings are better than the cultured seedlings through existing conventional seedling culturing substrates in the aspects of the vitality of root systems, sound seedling index, yield and the like.

Description

technical field [0001] The invention relates to a method for cultivating strong cucumber seedlings, which belongs to the field of agricultural technology. Background technique [0002] Vegetable 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 seed 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 seedling age is 10-20 days shorter than 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 quickly, and the survival rate is high. It is suitable for long...

Problems solved by technology

[0003] In the process of realizing the present invention, the inventors have found that there are at least the following problems in the prior art: the traditional plug seedling cultivation technology tends to cause the seedlings to grow excessively due to factors such as the plug seedling cultivation environment, resulting in a decline in the quality of the seedlings

Prohexadione calcium has low toxicity and low residue characteristics and is accepted by people. However, prohexadione calcium is easily degraded by microorganisms and has a short validity period. It is difficult to directly add prohexadione calcium to the seedling substrate to produce strong vegetable seedlings without increasing the dosage.
