Potassium chloride is suitable for use in combination with alkaline fertilizers
Potassium oxide is a physiologically acidic fertilizer, and when applied to soil over the long term, attention should be paid to applying it together with alkaline fertilizers such as lime to prevent soil acidification; it is most suitable for application on calcareous and alkaline soils. Potassium chloride must not be applied on saline soils, as it will worsen salt damage. Potassium chloride contains chloride ions, and chloride ions are related to crop quality. At present...

Pay attention when irrigating and fertilizing farmland: these four types of fertilizer are not suitable for application with water
The application method of fertilizing with water is also called "fertilizing with irrigation water". It is generally a topdressing method that provides supplementary nutrients during the period of rapid crop growth. Since it is supplementary fertilization, it cannot replace main fertilization methods such as base fertilizer. However, because this method is both convenient and quick-acting, it is widely used on vegetable land and on irrigated land where cash crops and special edible crops are grown...

Fewer Vegetable Diseases: Temperature, Light, Water and Fertilizer Regulation Is Key
Q: What is integrated water and fertilizer technology? What methods are commonly used at present? Expert: Strictly speaking, integrated water and fertilizer technology is dissolving fertilizer into irrigation water, using water to carry fertilizer so that water and fertilizer are supplied synchronously to the soil around the crop roots. One advantage of integrated water and fertilizer technology is that it can give play to the synergistic effect of fertilizer and water blending, making the benefits of fertilizer and water...

What are the growing conditions and suitable growing regions for Polygonatum odoratum (fragrant solomonseal)?
In what kind of orchards, woodlands, hillsides and farmland is Polygonatum odoratum suitable for planting? 1. Woodland (1) Site selection. Open woodland with a canopy density of 0.1-0.2 and vegetation of broadleaf forest or mixed coniferous-broadleaf forest is preferable; artificial coniferous forest is not suitable for planting Polygonatum odoratum. Requirements: slope <=20°, soil layer thickness >=15cm, pH value 5.5-7.0, and the soil should be humus soil or mountain brown earth. ...

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...

Excessive use of pesticides for pest control is not advisable; only rational use is safe
1. Chlorpyrifos easily causes phytotoxicity when used during the seedling stage of melon crops, and its use should also be avoided during the flowering period of certain crops. 2. Pesticides containing triazophos should not be used on fruit cane, as they easily cause phytotoxicity. 3. Because phoxim easily decomposes 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...

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...

How to use herbicides in vegetable fields safely? Master these key application points
Weeds in vegetable fields are a major problem in vegetable production. Hand weeding is both labor-intensive and backbreaking, so the vast number of vegetable growers need to use herbicides in vegetable production. However, vegetables come in many varieties, have short growing periods, high multiple-cropping indexes, and complex crop rotations, and there are also many types of herbicides. If used improperly, they can easily cause herbicide damage, or even total crop loss...

What herbicide is good for growing vegetables under insulation?
In seasons with lower temperatures, to bring vegetables to market earlier and sell them at a good price, in recent years the method of covering with plastic film has often been used to increase temperature and retain heat to promote early maturity and higher yields of vegetables, while also applying chemicals for weed control, which saves labor and increases efficiency. However, years of experience and lessons with chemical weed control under film tell us that if the selected...
