Rice promoting and control agent and preparation method thereof

Abstract

The invention discloses a rice promoting and control agent and a preparation method thereof and aims to solve the technical problems of rooting, tillering promotion and excessive growth control by stage according to the rice growth demands. The rice promoting and control agent is slow-release granules prepared from an active component and an auxiliary component, wherein the active component comprises a plant growth accelerant, a rooting agent and a plant growth retardant; the auxiliary component comprises a binder, a dispersant, a wetting agent, an adsorption carrier, filler and a coat. Duringpreparation, slow-release coating is performed on the plant growth retardant, and the periphery is coated with the plant growth accelerant and the rooting agent; after application, the plant growth accelerant and the rooting agent on the periphery take effect firstly to promote rooting and tillering, and the plant growth retardant begins to take effect to inhibit elongation of stem nodes when rice stems quickly elongate. The release rule of the granules completely conforms to the rice growth rule, control is performed after promotion, plants are not damaged, and the agent is used once and isconvenient and safe, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of plant growth regulation, in particular to a rice accelerator and control agent and a preparation method thereof. Background technique [0002] Rice is one of the most important food crops in the world, and improving rice yield has always been the main purpose of rice cultivation. Rice yield = number of spikes per mu × weight of spikes, the number of spikes per mu is the effective tiller number per mu of rice, and the influencing factors of spike weight are 1000-grain weight and the number of spikes, that is, the fullness of rice grains and the rate of empty grains in spikes, so the effective tillering of rice can be improved. It is an important cultural measure to increase rice yield by improving the degree of grain fullness and reducing the percentage of empty panicles and grains. [0003] Rice has the characteristic of tillering, and rice tillering mostly occurs at the very short tiller nodes at the ba...

Problems solved by technology

[0007] However, at present, most products for rooting, tillering and thriving control are simply mixed, causing problems in the use of regulators. They control thriving when they should be rooting, and they should be controlling thriving when they should be promoting tillering, which leads to conflicts between various components and damages rice seedlings. The effect of increasing production, but the problem of reducing production

[0008] After the rice turns green, the mixture containing both plant growth promoters and plant growth retardants will cause conflicts, affect the efficacy of the medicine, and damage the plants. In addition, this type of product is basically used after turning green on the market, and it has no effect on the speed of rice turning green. , can not play the effect of accelerating the rice planting, affect the low tillering, and reduce the effective tillering in the later stage

When rice is sprayed with plant growth retardants, the growth control is not obvious in small doses, and the large dose does not conform to the law of controlling growth while growing plants. late yield reduction

In many places, the plant height of rice is much lower than the normal plant height due to excessive control of prosperity, resulting in reduced yield

However, the use of multiple spraying separately leads to an increase in labor costs, which is labor-intensive and time-consuming.
