Rational application methods and technical key points for potassium fertilizer
Strawberries bloom and bear fruit continuously, with many flowers and a large fruit load, and a long flowering and fruiting period, so they consume a lot of phosphorus and potassium fertilizer. Once phosphorus is deficient and potassium is low during the flowering and fruiting period, cold resistance will decrease, few flowers will form, flower buds will be weak, and flowering and fruiting will be affected. Not only will the fruit-setting rate be low and the fruit prone to deformities, but the coloring will also be poor, the sugar content will drop, and the taste will be bland, ...

Methods and Key Technical Points for Applying Phosphate Fertilizer in Orchards
In spring and summer, the periods before and after flowering of fruit trees are stages prone to various diseases (physiological diseases and pathogen toxin diseases). At this stage, in addition to necessary chemical prevention, timely application of phosphorus and potassium fertilizers is also a good choice. However, many fruit growers tend to apply only nitrogen fertilizers (such as urea, high-nitrogen...

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:...

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...

What are the key technical points for foliar spraying of micronutrient fertilizers on vegetables?
Micronutrient fertilizers are indispensable nutrient elements in the growth and development of vegetables. Diluting micronutrient fertilizers and applying them as foliar fertilizer costs little, takes effect quickly and gives high returns. The key technical points are: 1. Spraying concentration. Only a suitable concentration can achieve good results; in particular, the concentration must not be too high, otherwise it is not only useless but harmful....

A Brief Analysis of Key Technical Points for Water and Fertilizer Management in Tobacco Fields
Compared with most other crops, the special characteristic of tobacco leaf is that the harvested part is the leaf. Tobacco leaves grow gradually as the tobacco plant roots continuously absorb nutrients and water from the soil. Therefore, to cultivate high-quality tobacco leaves, water and fertilizer management in tobacco fields is crucial. Scientific fertilization ensures yield and quality...

Key Technical Points for Integrated Water and Fertilizer Management in Mountain Orchards
Integrated water and fertilizer drip irrigation technology is a new agricultural technique that combines fertilization with drip irrigation. This technology uses a pressure system to dissolve soluble fertilizers into a nutrient solution, based on soil nutrient content and the fertilization characteristics of the crop, and delivers it together with irrigation water through pipes and drippers, evenly, at set times and in set amounts, to the crop root zone...

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...
