Problems solved by technology

[0002] Rice has always been used as a staple food in most areas of our country. The improvement of its quality and yield has always been the direction of people's research and efforts. For a long time, we have used high-concentration and highly toxic pesticides to prevent rice from insects and diseases to increase production. In recent years, the research on genetic engineering has enabled us to improve the yield and quality of rice by directional changes in rice genes through genetic engineering. However, the extensive use of pesticides has seriously polluted the environment, and even caused irreversible damage to some land, and the genetically modified rice Whether it has potential hazards has not yet been determined, and many people are not safe to eat;

Abstract

The invention discloses a rice plant growth regulator used in the reproductive stage. The rice plant growth regulator comprises the following components in proportion: 0.5-3.5ppm of 6-benzylaminopurine (kinetin), 20-30ppm of GA3 (gibberellin A3), 0.2-0.4ppm of triacontanol, 2-4ppm of compound sodium nitrophenolate, 15-25ppm of thiophanate-methyl, 1200ppm of ethanol and 800ppm of diethyl ether; and distilled water is used as a carrier.

Description

Technical field [0001] The invention belongs to the field of plant growth regulators, and particularly relates to a rice plant growth regulator during reproductive growth. Background technique [0002] Rice has always been used as a staple food in most areas of our country. The improvement of its quality and yield has always been the direction of people's research and efforts. For a long time, we have used high-concentration and high-toxic pesticides to prevent rice insects and diseases to increase yield. In recent years, genetic engineering research has allowed us to change rice genes in genetic engineering to improve yield and quality. However, the large-scale application of pesticides has seriously polluted the environment, and even caused irreversible damage to some land, and genetically modified rice Whether it has potential hazards has not yet been determined, and many people are not comfortable eating; [0003] The reproductive growth period of rice includes the jointing an...
