Common concentrations of several foliar fertilizers for crops?
The common concentrations of several foliar fertilizers for crops are as follows:
1. Urea:
The commonly used spraying concentration is 1%-1.5% (ie 1-1.5 kg urea to 100 kg water); within this range, the dicotyledonous plants may be suitably lower in concentration; the monocotyledonous plants may have a higher concentration; the seedling stage The concentration may be suitably lower; in the seedling stage, the concentration may be suitably higher. Generally, the spraying concentration of cereal crops is 1%-2%; the spraying concentration of vegetables, melons and fruits is 0.5%-1%; the spraying concentration of seedlings in seedling stage can't be higher than 0.2%.
2, zinc sulfate:
The commonly used spraying concentration is 0.1%-0.2%; a small amount of lime liquid is added to the solution and then sprayed.
3, borax (or boric acid):
The commonly used spraying concentration is 0.2%-0.3%; when preparing the solution, first dissolve the borax with a small amount of 45 °C hot water, and then apply enough water.
4, potassium dihydrogen phosphate:
The commonly used spraying concentration is about 0.3%; the preparation method is to take 300 g of potassium dihydrogen phosphate plus 100 kg of water, fully dissolved and sprayed. Urea and potassium dihydrogen phosphate can be used as needed.
5, paclobutrazol:
The fruit trees were sprayed with a solution of 1000-1500 mg/kg, and the crops were sprayed with a 50 mg/kg solution.
6, rice vinegar:
