1. Compound application of sodium nitrophenolate and foliar fertilizer
The mixed spraying of sodium nitrophenolate and foliar fertilizer can not only give full play to the effect of sodium nitrophenolate, but also improve the fertilizer efficiency by more than 30% without causing fertilizer damage, and the effect of increasing production and quality is extremely significant.
"Sodium nitrophenolate + potassium dihydrogen phosphate" compound application:
For fruit trees, nightshade vegetables, melons, and beans, in the flower bud stage or the fruit expansion stage, we can use 10 grams of 1.8% sodium nitrophenolate aqueous solution + 90 grams of potassium dihydrogen phosphate, and 30 kilograms of water per mu. Spraying can greatly improve the fruit set rate, promote fruit expansion, and significantly improve the yield and quality of melons and fruits. Among them, the spray concentration of potassium dihydrogen phosphate is 0.3%.
"Sodium nitrophenolate + urea" compound application:
For leafy vegetables, such as spinach, spinach, cabbage, and parsley, we can use 10 grams of 1.8% sodium nitrophenolate + 150 grams of urea and 30 kilograms of water for foliar spray per mu in any growth period of the vegetables. It can make the leaves of vegetables thicker and greener, and the vegetative growth of vegetables will be more vigorous, which can greatly improve the yield and quality of vegetables. The spray concentration of urea is 0.5%.
Note: Sodium nitrophenolate is very efficient, the amount per mu of land is extremely low, and the cost of spraying a pot is only a few cents to a few cents.
Sodium nitrophenolate has requirements for temperature during application. Its activity is high when the temperature is higher than 20 °C, and its activity is low when the temperature is lower than 15 °C. Therefore, we should not apply sodium nitrophenolate when the temperature is lower than 15 °C.
In conclusion, sodium nitrophenolate is an efficient plant growth regulator that integrates nutrition, regulation and yield increase. Its functions are very comprehensive. We spray it together with foliar fertilizer and chemical pesticides, which will neither cause fertilizer damage nor phytotoxicity. , but also can improve fertilizer efficiency and drug efficacy, and show a significant effect of increasing production and income.
