Spring planting fertilization tip: Effective potassium application boosts high yields in spring corn
Delayed senescence (staying green and late-maturing) refers to soybeans that, when they should be maturing, still have green branches and leaves with vigorous growth and seeds that are not yet plump, though not shriveled pods or shriveled seeds. The main cause of delayed senescence is excessive application of nitrogen fertilizer or application too late, causing excessive vegetative growth, delaying maturity, and affecting yield. To prevent delayed senescence in soybeans, it is necessary to timely...

Detailed Explanation of Key Points of Formula Fertilization Technology for Yardlong Beans
1. Symptoms mainly affect leaves, stems and vines, and pods. In the early stage of the disease, purple-brown spots appear on both sides of the leaves, and after expanding they become nearly circular dark brown lesions, 1-2 cm in diameter, with indistinct edges; when humid, the lesion surface is densely covered with sooty mold (especially prominent on the underside of the leaves). In severe cases, it causes early defoliation, leaving only the young leaves at the top, ...

Detailed Explanation of Fertilization and Water Management Techniques for Longan
I. Symptoms Young shoots, leaves and flower panicles can all be affected, and show obvious symptoms. The young leaves on diseased shoots are narrow and small, pale green, with curled leaf margins that cannot unfold, appearing tubular; in severe cases the entire leaf becomes linear and smoke-brown. The leaf surface of mature leaves is uneven, the leaf margins often curl and shrink toward the leaf underside, and the leaf tip bends downward; the leaf...

How to fertilize ginger for high yield? Detailed explanation of the key points of formula fertilization technology
Ginger has a long growing period and a high fertilizer requirement. Under medium fertility conditions, to produce general 2500 kg of ginger per mu, 25-40 kg of nitrogen, 10-22 kg of phosphorus (P2O5), and 30-50 kg of potassium (K2O) need to be applied. The absorption ratio of nitrogen, phosphorus, and potassium is 11:1:16 or 1:0.5:2. In addition, calcium, magnesium, boron, zinc, iron, and other medium and trace...

What are the key points of fertilization techniques for spring peanuts?
Calcium can promote pod formation, reduce empty pods and increase the number of filled pods; applying calcareous fertilizer such as lime to acidic soil can also reduce soil acidity and benefit nitrogen fixation by root nodules. Therefore, calcareous fertilizer can improve peanut yield and quality. When peanuts are deficient in calcium, plant growth is slow, roots are thin and seedlings are weak, and the edges and surface of old leaves will show...

Proper application of the four fertilizers is very important for spring peanuts, and the fertilization method must be mastered
Spring peanut cultivation with plastic film mulching has the advantages of heat preservation, moisture retention, fertilizer retention, improving the soil environment, ensuring uniform and strong seedlings, promoting growth and development, earlier maturity, and increased yield and income. It can usually increase yield by 20%-30%, and increase net income by 50-100 yuan per mu. 1. Fine land preparation and full-layer fertilization for peanut mulching...

Autumn basal fertilization for sweet cherries is timely now, and fruit growers should not miss it
When it comes to the key points of autumn basal fertilization, the first thing to emphasize is "early." It is generally carried out in September-October, but early application in September gives the best results. This is because during this period the soil temperature is relatively high, the roots absorb fertilizer over a longer time, and the absorption rate is also fast. Once the fertilization timing is grasped, the application rate must also be increased...
