Problems solved by technology

The high temperature stress in this period not only seriously inhibits the normal pollination and fruiting of early rice at the flowering stage, but also seriously affects the accumulation of starch and other carbohydrates in the early rice grains, inhibits the proliferation of endosperm cells and the process of filling and filling, and ultimately is not conducive to the formation of yield and rice quality.

Embodiment Construction

[0021] The present invention will be further described below in conjunction with embodiment, but the present invention is not limited to following embodiment, any identical or similar product with the present invention that draws under the enlightenment of the present invention, all within the scope of protection (note: The proportioning of each raw material in the embodiment is weight parts).

[0022] The present invention uses clear water, abscisic acid, sucrose (plant natural sucrose), abscisic acid+sucrose to carry out two spraying experiments respectively at the rice flowering stage and the initial stage of filling (10d after flowering) (during spraying, both the medicinal liquid and the clear water are added Added 0.5% surfactant,), specifically as follows:

[0023] In 2018, the experimental field of the China Rice Research Institute in Fuyang City, Zhejiang Province. Zhefu 802, an early indica rice variety tested, flowered from the end of June to the beginning of July....

Abstract

The invention discloses a high-temperature resistant rice plant growth regulator and a using method and application thereof, belonging to the field of promoting plant growth. The effective componentsof the regulator comprise abscisic acid and sucrose, and when in use, the concentration of the abscisic acid is 1-100 mu mol / L, and the sucrose accounts for 0.1-2.5% of the total mass of the regulator. According to the invention, based on the influence of the interaction of natural plant hormone abscisic acid and natural carbohydrate sucrose on the grain growth of rice after flowering, the optimalapplication concentration is screened, so that the high-temperature damage to the rice is remarkably reduced, the rice yield is remarkably increased, and the rice quality is remarkably improved.

Description

technical field [0001] The invention mainly relates to the field of promoting plant growth, in particular to a high temperature resistant rice plant growth regulator and its use method and application. Background technique [0002] In recent years, due to the increase of greenhouse gases caused by human production activities, the global climate is warming, which leads to frequent occurrence of extreme high temperature weather. Taking Zhejiang Province as an example, after the Meiyu period in July every year, it is controlled by the subtropical high pressure for a long period of time after that, and the weather is sunny and hot. If there is no typhoon here, continuous high temperature and summer drought will easily occur. According to statistics, the rice fields in the middle and lower reaches of the Yangtze River basically have extremely high temperature weather with an average maximum temperature greater than 38°C for 5 to 7 days every year from early July to mid-August, an...
