Scientific application methods and technical key points for potash fertilizer
Potassium is one of the three essential fertilizer elements. Many vegetables often require more potassium than nitrogen and phosphorus; well-grown vegetables contain potassium at 2.5%-7% of their dry matter, higher than their nitrogen and phosphorus content. Most vegetables absorb more potassium than nitrogen; for example, the nitrogen-to-potassium ratio absorbed by cucumber is 1:(1.5-1.7), by pumpkin is 1:2.1, and by tomato is 1:...

Application Methods of Potassium Fertilizer in Vegetable Cultivation
There are many types of potassium fertilizer, and different types have different application methods. Commonly used potassium fertilizers include potassium chloride, potassium sulfate, potassium-magnesium fertilizer and plant ash. Potassium chloride and potassium sulfate are physiologically acidic fertilizers and should be applied together with lime and organic fertilizer. For chlorine-sensitive crops such as potatoes, potassium chloride and potassium-magnesium fertilizer with high chlorine content should not be applied...

Key Technical Points and Detailed Methods of Foliar Fertilization
Do not spray in extremely hot weather or before rain, so as to avoid burning the seedlings or losing fertilizer nutrients. The best time to spray is in the early morning or afternoon each day, and after spraying, wait 7-10 days before spraying again. When spraying on cereal crops or crops with smooth leaves, add 0.1% adhesive (such as laundry detergent or dish soap), etc. Otherwise, the effect...

Correct Methods and Technical Key Points for Foliar Fertilization of Vegetables
Spraying an aqueous solution of the nutrients plants need onto the leaves, so that plants directly absorb effective nutrients through their leaves, is a technique called foliar fertilization of vegetables. Compared with soil fertilization, this technique has the advantages of rapid conversion, high fertilizer use efficiency, and promotion of nutrient uptake by the root system. Foliar fertilizers can be broadly divided into macro...

Detailed Explanation of Fertilizer Types and Application Methods (Part 6)
Achievement of Shandong Agricultural University: The fertilizer coating controlled-release technology involves spraying a uniform controlled-release film onto the surface of crop-specific compound fertilizer or urea granules. Its core technology lies in the film material and corresponding additives. By adjusting the formula, the number and size of pores on the film can be set to control nutrient release. Controlled-release fertilizer...

Application Methods and Technical Key Points of High-Efficiency Organic Fertilizer
I. How to Apply High-Efficiency Organic Fertilizer to Vegetables 1. Application Rate: According to the nutrient requirements of various vegetable crops, apply 60-100 kg per mu as base fertilizer for each crop of vegetables. Baosheng High-Efficiency Organic Fertilizer is mild in nature, and applying more is unlikely to cause fertilizer burn; for vegetables, melons and fruits with high economic value or high yield, the application rate may be increased by 20-50%. Baosheng...
