Method for using sodium nitrophenolate

Sodium nitrophenolate is a broad-spectrum plant growth regulator that can be used in general crops and can be used in any growing season, and both exhibit excellent results. After treatment, sodium nitrophenolate can quickly penetrate into plants, promote the flow of protoplasts in cells, promote cell division and proliferation, facilitate the synthesis of chlorophyll and protein, break seed dormancy, promote germination, hair roots, promote flower bud formation, and early flowering. And the weight gain of the fruit prevents the falling flowers from falling, and can eliminate the apical advantage of the formation of indole acetic acid, so as to facilitate the growth of axillary buds. For rice, wheat, beans, corn and other food crops, rapeseed, sesame and other oil crops, cotton, leafy vegetables, cruciferous vegetables, tomatoes, cucumbers, eggplants, watermelons, melons and other fruits, citrus, apples Fruits such as lychee, banana, longan, mango, pineapple, etc. can significantly increase crop yield, improve quality, and increase production and income.

Use technology

(]) break the dormant period

Barley, wheat: After seed soaking with sodium nitrophenolate solution, it can break the seed dormancy, promote germination and rooting, and make the buds thick and strong. Before planting the wheat seeds, 6000 times solution was prepared with 1.8% sodium nitrophenolate. After soaking for 12 hours, it was sown until it was half dry.

Rice: 1kg of rice seeds before sowing are soaked with 1L of 1.8% sodium nitrophenolate 6000 times for 12-24 hours, then drained and drained, then germinated.

Soy: Soak the seeds with 3mg/L of liquid for 3 hours, which has a good root-promoting effect.

Cucumber: Soak the seeds with 3mg/L liquid for 12 hours to make the seeds germinate quickly, the roots are developed, the seedlings are strong, and the disease resistance is improved.

(2) Adjust the proportion of male and female flowers, preserve flowers and preserve fruit, increase fruit weight

Citrus: In the 12-year-old ordinary Wenzhou mandarin experiment, the fruit setting rate was 28.67% higher than that of the control, higher than the plant health and the fruit. The medicinal solution of 1.4% sodium nitrophenolate 5000 times in the citrus flower Xie 14 days. Spray again 1-7 days, then spray once every 30 days.

Apple: Spraying 6mg/L sodium nitrophenolate solution once every 20 days before flowering, before flowering, in young fruit, and during fruiting, can increase yield and improve apple quality. The specific performance is as follows: the nitrogen content in apple leaves is increased by 1.6%, the phosphorus is increased by 0.3% to 19.5%, and the amino acid is increased by 0.9%-3.9%; the various nutrients in the fruit are improved, potassium is 6.0% to 66.5%, and calcium is 5.0%. ~ 83.0%, phosphorus 2.2 times, protein 1.6 times, amino acid 41.4% -130.4% (in which aspartic acid increased 1.6-4.7 times, valine l5 ~ 3.2 times), vitamin c 5.8% ~ 11.8%, while also making The fruit hardness is greatly increased, which prolongs the storage period and the supply and marketing period.

Pear: The test showed that after applying 1.8% sodium nitrophenolate 5000 times, the fruit setting rate increased by 6%-25.53%, the yield increased by 18%-21.5%, the weight of single fruit increased by 15.69%, and the soluble solid matter increased by 0.85%~1.1%.

Grape: The application of sodium nitrophenolate can increase the fruit setting rate and the effect is very outstanding. For example, in the first 7 days before the grape flower and after spraying 1.8% sodium nitrophenolate 1 times 5000 times, the fruit setting rate can be increased by 78.97%. If 6000% solution is added to 0.2% borax, the fruit setting rate can be increased by 80.9%. With 4000 times solution, 1.8% sodium nitrophenolate and 0.3% borax can increase the fruit setting rate by 84.69%.

Litchi: Spraying 1.8% sodium nitrophenolate 3000 times before and after flowering can increase soluble solids, increase yield and improve litchi quality.

Tomato: 1.8% sodium nitrophenolate 4000 times in the seedling stage, flowering stage and young fruit formation period, which can increase the plant height, significantly increase the fruit setting rate and effectively increase the yield.

Cucumber: Spraying with 8% sodium nitrophenolate 6000 times in the young fruit stage, early flowering stage and early fruit stage can increase the number of female flowers, increase the rate of sitting melon, reduce the rate of melon, increase the yield significantly, and make Cucumber harvest early, straight, bright green, sweet and refreshing, improve product quality.

Watermelon: Spraying l.8% sodium nitrophenolate 6000 times in the seedling stage, the vine growing stage, the flowering stage and the fruiting stage, the growth activity of the melon can be enhanced, the wilt disease plant is reduced, and the rate of sitting melon is increased. Single melon gain, increase yield and sugar content.

Dongzao: Spraying 1.8% sodium nitrophenolate 6000 times in the flowering, young fruit, expansion and white ripening periods can increase the fruit setting rate and high yield.

(3) Promote the vegetative growth of crops, increase the growth rate, increase the amount of production, and improve the quality of agricultural products.

Rice: use sodium nitrophenolate before and during the transplanting of seedlings to promote the rapid growth of rice, improve the uniformity and seed setting rate, generally increase yield by 12% -22%, and spray rice seedlings 4 to 5 days before transplanting. Apply once, spray each time at the booting stage and the heading stage, and use a concentration of 500% to 600 times solution of 1.8% sodium nitrophenolate, and spray 50 times per acre.

Barley, wheat: using 1.8% sodium nitrophenolate 3000 times in the seedling stage, jointing stage and filling stage, can significantly increase the 1000-grain weight. Increase production and improve quality.

Sorghum: Before the heading and the flowering stage, foliar application of 1.8% sodium nitrophenolate 4000-6000 times, 50 kg per acre, has the function of improving quality and increasing yield.

Soybean: Spraying 1.8% sodium nitrophenolate 4000 times in the flower bud formation stage, the initial pod stage and the young pod stage, which can increase the 100-grain weight of soybean, increase the yield, and improve the quality of soybean, crude protein and The crude fat content increased significantly.

Green beans: The test showed that spraying 1.4% sodium nitrophenolate 5000 times liquid and 6000 times liquid increased yield by 27.36% and 25.9%, respectively, and the harvesting period was 8-10 days earlier. In the seedling stage and initial flowering stage of the green beans, use 1.4% sodium nitrophenolate 5000-6000 times, spray 40-5Okg per acre every 7 to 19 days, spray a total of 3-4 times. The optimum concentration of 1.8% sodium nitrophenolate is 5000-6000 times; if the concentration exceeds 3000 times, it has inhibitory effect on the plant; if the concentration is less than 9000 times, the effect is not significant. The optimum application period of green beans is the initial flowering period. At this time, the medicine is beneficial to preserve the flowers and increase the pods. If it is applied too early or too late, the effect is not as remarkable as the initial flowering period.

Tea tree: After spraying sodium nitrophenolate, it showed a variety of physiological effects: First, the spacing of the bud leaves was elongated, and the bud weight was increased. The bud weight was determined to increase by 9.4% compared with the control; the second was to stimulate the germination of adventitious buds and increase the germination density. 13.7%; the third is to increase chlorophyll content, improve photosynthesis ability, and increase leaf color. According to the average of 2 years of experiment, spring tea increased yield by 25.8%, summer tea increased yield by 34.5%, autumn tea increased yield by 26.6%, and annual average yield increased by 29, 7%. Tea gardens usually use a dilution factor of 5000 times, and spray 12.5 mL of water per 667 mu with 50 kg of water. The ridges of the tea buds before the germination of each season can promote the early development of axillary buds. However, in the early stage of spring tea, it has more economic value, that is, the first bud and one leaf are sprayed at the initial stage, and the tea has strong absorption capacity and obvious effect of increasing yield. Spring tea is generally sprayed about 2 times. Summer and autumn tea can be combined with pest control and pesticide mixing, evenly sprayed on the front and back of the leaf, wet without dripping to moderate, to achieve two effects of pest control and growth.

Cotton: Spraying sodium nitrophenolate once in the early, flowering and expanded peach stages can significantly increase the fruit setting rate and increase the yield. The test shows that seed cotton can increase yield by 29.3% and lint yield by 20.2%.

Rapeseed: Spraying 1.4% sodium nitrophenolate 5000 times in the regreening stage, early flowering stage and final flowering stage can significantly increase the effective angle, increase the 1000-grain weight, and increase the yield.

Tobacco: Spraying twice the leaf surface of the whole plant with a mixture of 1.8% sodium nitrophenolate 12000 times for 10 days, the yield increased significantly, which increased the proportion of superior smoke and greatly increased the output value.

Sugarcane: Spray with 1.8% sodium nitrophenolate 3500 times in the seedling stage, tillering stage and elongation stage to increase tillering, which can promote early maturity increase and increase sugar content.

Peanut: Sprayed with 1.8% sodium nitrophenolate 3000 times in the 4, 8 and 12 leaf stages of peanut main stems respectively. The leaves are dark green, which can reduce leaf spot disease and increase the number of pods and seeds. Heavy, especially the number of full fruits increased, the rate of fruit filling increased, and the effect of increasing yield was significant.

Beet: Spraying twice with 1.8% sodium nitrophenolate in the growth period to increase the weight and root weight of the sugar beet and increase the sugar content.

Mushroom: With 1.8% sodium nitrophenolate 6000 times in the tide period and seed body formation period, the effect of increasing yield is significant, and the harvesting period and quality of the mushroom can be prolonged.

The similar products of sodium nitrophenolate are sodium nitrophenolate and sodium nitrophenolate. They differ from sodium nitrophenolate in that the hydroxy group on the benzene ring is different in ion and the physical properties are slightly different. The chemical properties are almost the same as the biological activity. The application in agricultural production is also roughly the same. Since the physical properties of sodium nitrophenolate are more stable, most of the agricultural production uses sodium nitrophenolate.

Precautions

(1) When the concentration is too high, it has an inhibitory effect on crop shoots and growth.

(2) Spray evenly, plants with more waxy substances should be sprayed with appropriate amount of spreading agent.

(3) It can be mixed with pesticides and fertilizers, and the effect is better.

(4) The tobacco leaves are used 30 days before harvesting.

(5) Store in a cool place.
