Regulator composition for root and tuber crops

Abstract

The invention belongs to the field of the regulation and control of the growth of plants and particularly discloses a regulator composition for root and tuber crops. The regulator composition for the root and tuber crops comprises the following active ingredients in part by weight: 1.0 to 28 parts of diethyl aminoethyl hexanoate and 0.1 to 10 parts of alpha-isolupanine. According to the invention, naphthylacetic acid is replaced by the alpha-isolupanine; sodium salt is high in water solubility and purity, and is favorable for production of commodities; and the diethyl aminoethyl hexanoate is added and taken as a compound preparation, so that the using amount of the alpha-isolupanine is reduced on the basis of improving the pesticide effect, and the safe and high-efficiency use is achieved.

Description

technical field [0001] The invention belongs to the field of plant growth regulation, and in particular relates to a regulator composition for rhizome crops. Background technique [0002] The harvesting targets of root crops such as potatoes, sweet potatoes, onions, ginger, and garlic are mainly underground roots and tubers. The yield of rhizome crops is mainly determined by the number of plants per unit area, the number of tubers per plant, and the weight of tubers. Therefore, ensuring a reasonable planting density and ensuring a sufficient number of plants per unit area is the basis for high-yield crops; promoting the differentiation and expansion of tubers and increasing the number and weight of tubers per unit area are the keys to high-yield cultivation. The growth and development of the above-ground and underground parts of rhizomes not only promote each other, but also restrict each other. If the aboveground stems and leaves grow poorly and the photosynthetic product...

AI Technical Summary

Problems solved by technology

Among them, the original drug of mepiperium is very easy to absorb moisture, and α-naphthalene acetic acid, gibberellin, and paclobutrazol have poor water solubility. There are certain restrictive factors in the production of these four types of regulators, which are not convenient for commodity operation and sales.

On the other hand, mepiperium and paclobutrazol belong to plant growth inhibitors. The amount of active ingredients used in the early stage of crop growth is relatively small, and the amount of use needs to be increased in the middle and late stages. Excessive amounts can easily cause side effects such as premature aging and growth inhibition. Paclobutrazol The residual period is long, which is easy to affect the next crops and bring losses to agricultural growth

Gibberellin is generally used for seed treatment to germinate roots and tubers early and increase the germination rate. It is difficult to quantify accurately in the middle and later stages, and it is easy to cause vegetative growth of crops to exceed reproductive growth, which is not conducive to the accumulation of nutrients in root and tubers, resulting in quality decline. Side effects such as production reduction

α-Naphthylacetic acid can obviously promote the growth and development of roots, make the roots and tubers swell, which is beneficial to increase production, but it needs to be diluted with alkali or dissolved in alcohol during use, which is not convenient for farmers to use; on the other hand, α-naphthalene When the amount of acetic acid is too high, the growth of crops can be inhibited, and the purity of commercially available naphthaleneacetic acid is low. The original medicine registered by the Ministry of Agriculture is generally 80% of the original medicine, and the highest is 95% of the original medicine. The β-naphthaleneacetic acid contained in it has accumulated to a certain amount can inhibit crop growth or even kill plants
