Problems solved by technology

[0004] Chinese patent CN104719293 discloses a chemical control method for preventing lodging of large panicle rice varieties. The patent is to select the critical leaf age for effective tillering of rice and spray a certain concentration of gibberellin solution on the leaves. Although this invention has lodging resistance effect, but it is lacking in improving crop quality and increasing crop yield

Embodiment 1-5

[0037] Table 1 lists 5 specific examples of a rice growth regulator of the present invention.

[0038] The rice growth regulator formula of table 1 embodiment 1-5

[0039]

[0040]

[0041] The preparation method of the embodiment of the present invention is as follows:

[0042] (1) Weigh triacontanol, gibberellin, urea, potassium dihydrogen phosphate and boric acid by percentage;

[0043] (2) Dissolve the weighed gibberellin in ethanol, then add triacontanol and mix evenly to obtain solution A;

[0044] (3) The weighed urea, potassium dihydrogen phosphate and boric acid are dissolved in water to make mixed nutrient element solution B;

[0045] (4) Add A to B, and stir evenly while adding;

[0046] (5) Finally, add soil temperature 20 or soil temperature 80, and stir evenly to obtain the rice growth regulator solution.

[0047]The rice growth regulator is sprayed on the leaves of rice at the tillering stage, jointing stage and full heading stage. On a sunny and wind...

Abstract

The invention discloses a rice growth regulator. The rice growth regulator is composed of 0.001 to 0.005% of triacontanol, 0.001 to 0.01% of gibberellin, 1 to 5% of urea, 0.2 to 0.8% of potassium dihydrogen phosphate, 0.2 to 0.8% of boric acid, 0.02 to 0.08% of a dispersing agent, 1 to 10% of ethanol and the balance of water. The rice growth regulator is sprayed to leaf surfaces in rice tillering, jointing and full heading periods. Triacontanol and gibberellin produce synergism so that the lodging resistance of rice is improved. The regulator and the chemical fertilizer are used together so that the absorption of the chemical fertilizer and dry matter accumulation of the rice are promoted and a rice yield and quality are improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a rice growth regulator and a preparation method thereof. Background technique [0002] Rice is one of the most important food crops in the world. About 1 / 3 of the world's population uses rice as a staple food. 90% of rice growers and consumers are in Asia. With the development of production and the improvement of people's living standards, The rice quality problem has aroused various concerns and discussions. Lodging is a ubiquitous problem in crop production. After lodging, the rice leaves overlap each other, and the photosynthetic area and group photosynthetic efficiency are reduced, which affects grain filling, shattering, shriveled grains, and ear germination. Lodging will cause harvesting difficulties, increase rice loss rate, and reduce rice yield and quality. At present, using plant growth regulators to improve rice lodging resistance is the most direct and effecti...
