Urea and potassium dihydrogen phosphate are important nutrients required for crop growth, and their combined spraying can provide crops with comprehensive nitrogen, phosphorus and potassium nutrients and promote healthy crop growth. This recipe is especially effective for the growth of vegetables. In the vegetable growth period, 50 grams of urea and 50 grams of potassium dihydrogen phosphate can be used per mu, mixed with 20 kg of water for foliar spraying. Spraying 2-3 times in a row every 10 days can make the leaves greener and increase the yield.
The combined spraying of urea and glucose can also effectively improve the photosynthesis efficiency of crops and accelerate the synthesis of photosynthesis products. For the growth of vegetables, it is especially suitable for crops with lush leaves. Foliar sprays of 100 grams of urea and 50 grams of glucose mixed with water for 20 kg can make the leaves of the crop greener, thicker and grow significantly faster.
Weeds are a major problem in crop growth, and spraying chemical herbicides is a common method of weeding. However, sometimes herbicides alone are not effective, and urea can be added to enhance the weeding effect. Urea solution can soften the stratum corneum of weed's epidermal cells, promote the herbicide to better penetrate into the weed, thereby improving the weeding effect. When spraying herbicide, add 30 grams of urea to each pot of herbicide solution, fully stir and spray, which can significantly improve the weeding effect.
Amine fresh ester is a highly effective plant growth regulator, which can be used in combination with fungicides, insecticides, and foliar fertilizers. It is especially suitable for the cultivation of leafy vegetables and fruits and vegetables. For leafy vegetables, 100 grams of urea and 10 grams of 8% amine fresh ester can be used per mu, mixed with 20 kg of water for foliar spraying, which can promote the vegetative growth of crops and make the leaves thicker and greener. For fruits and vegetables, 50 grams of dipotassium phosphate and 10 grams of 8% amine fresh ester can be used per mu, mixed with 20 kg of water for foliar spraying, which can significantly improve the fruit setting rate and disease resistance of melons and fruits, ensure high yield and increase yield.
Urea is an important nitrogen fertilizer, and its potential to increase yield and promote growth can be fully realized through different formulations and application methods. The combined spraying of urea and potassium dihydrogen phosphate can meet the demand of crops for nitrogen, phosphorus and potassium and improve the healthy growth of cropsThe combined spraying of urea and glucose can improve the efficiency of photosynthesis and promote the synthesis of photosynthesis products of cropsUrea and herbicide spraying can enhance the effect of herbicides and improve weeding efficiencyThe combination of urea and amine ester can promote the vegetative growth of plants and increase yield. When using urea for foliar spraying, it is necessary to pay attention to the choice of spraying concentration and spraying time to avoid fertilizer damage or affect the spraying effect.
As a commonly used nitrogen fertilizer, urea plays a vital role in vegetable cultivation. Through different formulas and spraying, the fertilizer efficiency of urea can be fully exerted, and the yield and quality of crops can be improved. In practice, I have found that urea can be synergistically combined with other nutrients and pesticides to better meet the nutritional needs of crops and the need to control pests and diseases. These ** formulations not only improve the growth rate and yield of crops, but also improve the stress resistance and quality of crops. Therefore, while using urea, it can be reasonably combined with other fertilizers and pesticides to make crops grow and develop better, and achieve high-yield and high-quality agricultural output.
