Sodium nitrophenolate, also known as sodium nitrophenolate, is one of the three major plant growth regulators and has a wide range of uses. Sodium nitrophenolate is usually diluted with water before use. So how much water should one gram of sodium nitrophenolate be diluted with? Let's find out.
How much water should be mixed with one gram of sodium nitrophenolate?
One gram of sodium nitrophenolate is usually diluted with 1 liter of water. When used on rice, wheat , or corn, one gram of sodium nitrophenolate can be diluted with 120-180 jin of water. It is used during the sowing, transplanting, booting, and early grain-filling stages.
The role of sodium nitrophenolate
1. Break the dormancy period
Sodium nitrophenolate can break seed dormancy, promote germination and root development, resulting in thicker and stronger seedlings and the formation of flower buds. Before sowing wheat, a 6000-fold dilution of 1.8% sodium nitrophenolate can be used to soak seeds for 12 hours, then they can be dried until semi-dry before sowing.
2. Preserve flowers and fruits
Sodium nitrophenolate promotes earlier flowering and increased fruit weight, prevents flower and fruit drop, and eliminates apical dominance caused by indoleacetic acid , thus facilitating axillary bud growth. Spraying with a 6 mg/L sodium nitrophenolate solution once each—20 days before flowering , before flower fall, during the young fruit stage, and during the fruit expansion stage—can increase yield and improve quality.
3. Promotes growth
Sodium nitrophenolate can promote crop growth and increase crop growth rate. It can be applied before seedling transplanting and during the field stage to help rice quickly recover its growth capacity, improve uniformity and grain filling rate, and generally increase yield by 12%-22%. It can be sprayed once 4-5 days before rice seedling transplanting, and twice during the booting and heading stages. The spray concentration is 1.8% sodium nitrophenolate aqueous solution diluted 500-600 times, with a 50-fold dilution per acre each time.
Precautions for using sodium nitrophenolate
1. Spray evenly. For plants with a lot of wax, add an appropriate amount of spreading agent before spraying.
2. Tobacco leaves should cease use 30 days prior to harvest;
3. Store in a cool, dark place.
