Sodium nitrophenolate is a broad-spectrum plant growth regulator that can be used for general crops with good results.
Usage technology
1. Breaking dormancy
(1) Barley and wheat: Soaking seeds in sodium nitrophenolate solution can break dormancy, promote germination and rooting, and make the buds thick and the seedlings strong. Before sowing wheat seeds, prepare 6000 times solution with 1.8% sodium nitrophenolate, soak the seeds for 12 hours, and then dry them until they are half dry before sowing.
(2) Soybean: Soak the seeds in 3mg/L solution for 3 hours, which has a good root-promoting effect.
(3) Cucumber: Soak the seeds in 3mg/L solution for 12 hours, which can make the seeds germinate quickly, develop a well-developed root system, and make the seedlings strong, thus improving disease resistance.
2. Adjust the ratio of male and female flowers, preserve flowers and fruits, and increase fruit weight
(1) Apple: Spray 6 mg/L sodium nitrophenolate solution once 20 days before flowering, before flower drop, during young fruit stage, and during fruit swelling stage to increase yield and improve apple quality.
(2) Pear: Experiments show that after applying 1.8% sodium nitrophenolate solution at 5000 times dilution, the fruit setting rate increased by 6%-25.53%, the yield increased by 18%-21.5%, the single fruit weight increased by 15.69%, and the soluble solids increased by 0.85%-1.1%.
(3) Grape: Spray 1.8% sodium nitrophenolate solution at 5000 times dilution once 7 days before flowering and after flowering to increase the fruit setting rate by 78.97%. If 0.2% borax is added to the 6000-fold solution, the fruit setting rate can be increased by 80.9%. If 0.3% borax is added to the 4000-fold solution of 1.8% sodium nitrophenolate, the fruit setting rate can be increased by 84.69%.
(4) Tomato: Use 4000-fold solution of 1.8% sodium nitrophenolate once in the seedling stage, flowering stage and young fruit formation stage to increase plant height, significantly increase fruit setting rate and effectively increase yield.
(5) Cucumber: Use 6000-fold solution of 1.8% sodium nitrophenolate once in the young fruit stage, early flowering stage and early fruit stage to increase the number of female flowers, increase fruit setting rate, reduce fruit melting rate, significantly increase yield, and make cucumbers harvested earlier. The cucumbers are straight, bright green, sweet and refreshing, and the product quality is improved.
(6) Watermelon: Spray once with 1.8% sodium nitrophenolate (6000 times diluted) at the seedling stage, vine extension stage, flowering stage and fruiting stage. This can enhance the growth vitality of melon vines, reduce the number of plants with wilt diseases, increase the fruit setting rate, increase the weight of each fruit, and increase the yield and sugar content.
3. Promote the nutritional growth of crops, increase yield, and improve the quality of agricultural products
(1) Barley and wheat: Spray once with 1.8% sodium nitrophenolate (3000 times diluted) at the seedling stage, jointing stage and filling stage. This can significantly increase the thousand-grain weight. Increase yield and quality.
(2) Sorghum: Spray 1.8% sodium nitrophenolate (4000-6000 times diluted) on the leaves before heading and during flowering. Use 50 kg per mu each time. This can improve quality and increase yield.
(3) Soybean: Spraying once with 4000 times of 1.8% sodium nitrophenolate solution at the bud formation stage, early pod setting stage and young pod stage can increase the 100-grain weight of soybeans and increase yield. At the same time, the quality of soybeans is also improved, and the crude protein and crude fat content are significantly increased.
(4) Cotton: Spraying sodium nitrophenolate solution once at the early stage, flowering stage and fruit swelling stage can significantly increase the fruit setting rate and increase yield. Tests show that seed cotton can increase yield by 29.3% and lint cotton by 20.2%.
(5) Rapeseed: Spraying once with 5000 times of 1.4% sodium nitrophenolate solution at the greening stage, early flowering stage and final flowering stage can significantly increase the number of effective siliques, increase the 1000-grain weight and increase yield.
(6) Peanuts: Spray 1.8% sodium nitrophenolate at 3000 times dilution once at the 4, 8, and 12 leaf stages of the main stem of peanuts. The leaves will turn dark green, which can reduce leaf spot disease, increase the number of fruits, make the pods and kernels heavier, and especially increase the number of full fruits, improve the full fruit rate, and significantly increase the yield.
(7) Beet: Spray 1.8% sodium nitrophenolate at 6000 times dilution twice during the growth period to increase the plant weight and root weight of beets and increase the sugar content.
