Do organic fertilizers need to be composted before application?
The composting of organic fertilizers occurs through the activity of microorganisms, causing two kinds of changes in the organic fertilizer. On one hand, the organic matter decomposes, increasing the available nutrients in the fertilizer; on the other hand, the organic matter in the fertilizer changes from hard to soft, its texture changes from uneven to uniform, and during composting most weed seeds, pathogens and insect eggs...

Bt insecticide application techniques matter; mastering the method is key
Ethephon is an organophosphorus broad-spectrum low-toxicity plant growth regulator that promotes ripening. It can enter the plant through leaves, bark, fruit, and seeds, then be transported to the sites where it acts, releasing ethylene. It can promote fruit ripening and coloring, promote the abscission of leaves and fruit, dwarf plants, and change the ratio of female to male flowers...

What are the precautions for combined fertilizer application
The solution made by soaking onion skins not only contains a substance that can kill pathogenic microorganisms in the soil, but also contains a variety of trace elements, and can be used as fertilizer for crops. 1. When growing flowers indoors, if the onion skin soaking solution is used as fertilizer, the flower branches grow luxuriantly and the flowers are more brightly colored. 2. Yellowing and withering cucumber seedlings are especially suitable for onion...

The Benefits of Deep Fertilizer Application and the Correct Application Methods
In recent years, production practice has proven that deep fertilizer application is a technical measure for improving fertilizer efficiency, reducing costs and increasing yields. I. Main forms of deep fertilizer application technology 1.1 Deep application of base fertilizer Use a fertilizing and soil-preparation machine, or add a fertilizer box and fertilizer-discharging device to a moldboard plow or paddy field tillage machine, so that while turning the soil it applies...

Reasonable Application Methods for Water-Soluble Fertilizers
Plants need to absorb various nutrients for growth and development. However, what determines crop yield is the nutrient factor present in the smallest relative amount in the soil, and yield also changes relatively within a certain limit as this factor increases or decreases. This is usually explained using a water-filled wooden bucket. The bucket is made of staves representing different nutrient contents and factors...

Correct Application Methods for Water-Soluble Fertilizers
Water-soluble fertilizer (WSF) is a multi-element compound fertilizer that dissolves completely in water. It dissolves rapidly in water, is more easily absorbed by crops, and has a relatively high absorption and utilization rate. More importantly, it can be applied in facility agriculture such as spraying and drip irrigation, achieving...

How to choose insecticide application timing and spraying site
1. Chlorpyrifos is prone to causing phytotoxicity when used during the melon seedling stage, and its use should also be avoided during the flowering period of some crops. 2. Pesticides containing triazophos are not suitable for use on fruit cane, as they easily cause phytotoxicity. 3. Because phoxim decomposes readily when exposed to light, its use should be avoided during the watermelon growing period and the seedling stage of radishes and leafy vegetables (even during the growing period...

Foliar fertilizer application must be tailored to the specific problem
The effectiveness of phosphate fertilizer application depends both on the total amount of available phosphorus in the soil and on the soil properties; for example, some soils can promote the dissolution of sparingly soluble phosphates, while other soils can cause the fixation of soluble phosphates. Generally, after phosphate fertilizer is applied to the soil, it quickly combines with iron, calcium and aluminum in the soil...

Application of Plant Growth Regulators in Fruit Production
Growth Disorders and Countermeasures - Application of Growth Regulators in Watermelon Growth Regulation: Improving Seed Vigor - Regulating Plant Growth - Improving Fruit Set Rate - Fruit Ripening - Preventing Fruit Cracking - Post-harvest Preservation. Improving Seed Vigor: In winter-spring cultivation of watermelon, low temperatures and poor environmental conditions result in slow and uneven emergence. Using Chinese Academy of Agricultural Sciences...

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, ...
