How to remedy potassium and magnesium deficiency in greenhouse strawberries
I. Potassium deficiency: The symptoms of potassium deficiency in strawberries often appear first on the newly matured upper leaves. Black, brown and dried edges often appear on the leaves and then become scorched, and it also spreads toward the center between the veins of most leaves, with old leaves being severely affected. Light intensifies leaf scorch, so potassium deficiency is often confused with "sunscald"...

For good quality and high yield in Welsh onions, reducing nitrogen and increasing potassium fertilization is key
In recent years, in order to increase Welsh onion yields, many vegetable growers have blindly increased the use of chemical fertilizers, especially nitrogen fertilizers. According to surveys, on average, pure nitrogen applied to Welsh onions per mu is as high as 40-50 kg, and phosphorus pentoxide 10-15 kg, while potassium fertilizer is applied very little or not at all, resulting in Welsh onion yields not increasing but decreasing, and root rot becoming more severe...

What are the control methods for potassium deficiency in pear trees
Villagers reported that in a pear orchard in a mountain village, some pear tree branches were found to have shortened internodes, smaller leaves that were yellow-green in color, with leaf margins curling upward, browning, and scorching; in severe cases, the entire tree's leaves were like this, resembling fire damage, and it was even more severe on trees in poor, thin soil with exposed roots, affecting tree vigor and yield. Many fruit growers could not figure out...

Beware of excess nitrogen and insufficient potassium when planting zucchini in spring
Guard against too much nitrogen and too little potassium. Zucchini's demand for nitrogen, phosphorus and potassium is greatest for potassium, followed by nitrogen, and least for phosphorus. Spring temperatures are relatively high, and if there is too much nitrogen fertilizer, zucchini can easily grow leggy. Therefore, when topdressing in spring, be sure to apply less nitrogen fertilizer and focus on high-potassium compound fertilizer. Guard against high temperature and drought. Zucchini is not tolerant of high temperatures, and high temperature...

How to scientifically apply potassium fertilizer during the middle and late stages of grape growth
Potassium fertilizer is very important throughout the entire growth period of grapes, especially during fruit development when the demand is even greater. Therefore, grapes are known as a "potassium" crop. Potassium fertilizer can promote grape fruit enlargement and ripening, improve variety quality and storage tolerance, promote branch thickening and maturation, and enhance their cold resistance, drought resistance, high...

Technical methods for phosphorus and potassium fertilizer management for high-yield maize
The effect of applying phosphorus and potassium fertilizers varies greatly depending on the soil's available nutrient content. Increasing the application of phosphorus and potassium helps produce strong seedlings that emerge early, strong plants with large ears, a higher grain-to-leaf ratio, and more grains and greater grain weight, and is an important condition for improving population quality. However, after phosphorus and potassium fertilizers are applied, most are absorbed and fixed by the soil, the absorption and utilization rate in the current season is low, and in the soil...

What to Do About Potassium Deficiency in Melons? Detailed Prevention and Control Methods
While inspecting the growth of watermelons and melons, a few melon plants at the flowering and fruiting stage were found to be affected by sclerotinia rot. This disease generally occurs sporadically and has no obvious impact on melon production. In a few greenhouses, however, the incidence was more severe, causing dead vines and rotten melons and affecting yield. Prevention and control methods: (1) Pay attention to ventilation and dehumidification, and promptly remove old leaves at the base during the growing period...

Pineapple fertilization: pay attention to supplementing nitrogen and potassium fertilizers
Because root-knot nematodes parasitize in the roots and cause the root tissue to overgrow, forming tumors of varying sizes. Control method: implement quarantine; plants carrying nematode disease must not be brought to disease-free areas. When opening a new orchard, plow and harrow the soil to expose it to the sun in clear weather; sunlight exposure can also kill root-knot nematodes.

When should potassium fertilizer be applied to pineapple? Now is a good time
At present, pineapple winter fruit has entered the stage of rapid expansion, color change and ripening, and the demand for potassium fertilizer is large. If potassium fertilizer is supplied sufficiently at this time, the pineapple winter fruit can expand rapidly and ripen fully, with large fruit, regular fruit shape, plump fruit, clear and sweet flesh, plenty of juice, strong aroma, good coloring, golden peel, and good storage and transportation tolerance. Otherwise...
