Composition capable of promoting rooting survival of plantlets

Abstract

The invention discloses a composition capable of promoting rooting survival of sweet potato plantlets. The composition is prepared from, by mass, 1.5 parts of alpha-naphthylacetic sodium salt and 4.5 parts of indole butyric acid potassium. The invention further provides an agentia capable of promoting rooting of the plantlets. The agentia is prepared from, by mass, 1.5 parts of the alpha-naphthylacetic sodium salt, 4.5 parts of the indole butyric acid potassium and water, wherein the using amount ratio of the water to the alpha-naphthylacetic sodium salt is 1 L:1.5 g, and the using amount ratio of the water to the indole butyric acid potassium is 1 L:4.5 g. The agentia is simple in using method, convenient to operate in a field, easy to apply in production and obvious in effects of rooting promoting and yield increasing of the sweet potato plantlets.

Description

technical field [0001] The invention belongs to the field of plants and relates to a composition for promoting rooting and survival of plant seedlings. Background technique [0002] Sweet potato (scientific name: Dioscorea esculenta (Lour.) Burkill), also known as sweet potato, sweet potato, sweet potato, sweet potato, sweet potato. Sweet potato is a cross-pollination crop, self-infertile, and the offspring propagated by seeds have large differences in traits and low yield. Therefore, seed propagation is rarely used in production. Because the vegetative organs such as sweet potato tubers and vines have strong regeneration ability and can maintain good seed properties, vegetative organs such as potato tubers, vines, and potato tips are used in production to reproduce offspring. Root tuber seedling propagation is a commonly used propagation method for sweet potato production. This method utilizes the characteristic that the adventitious bud primordia hidden under the skin ar...

AI Technical Summary

Problems solved by technology

[0007] At present, although the low survival rate of potato seedlings after transplanting often occurs in sweet potatoes, and the lack of seedlings in the field leads to reduced production, the technology of using plant growth regulators to promote rooting of sweet potato seedlings in production is rarely used.

The main reason is that different plants have different sensitivities to plant growth regulators, and the effect of promoting rooting is also different. Moreover, the excessive concentration of plant growth regulators also has the effect of inhibiting rooting. Existing plant growth regulator products are not designed for sweet potato. Research and development, the rooting effect on sweet potato seedlings is not ideal, potato farmers want to use it but can't find a suitable growth regulator
