Liquid organic phosphorus fertilizer is produced using pumpkin seeds and sugarcane as raw materials, through a series of physical processing steps without any chemical additives, with a phosphorus content exceeding 20%. This product contains no harmful substances and serves as a high-efficiency liquid fertilizer for producing green, organic, and pollution-free agricultural products.
It not only replenishes phosphorus but also improves soil structure, enhances microbial activity, and promotes healthier soil. Proper application of phosphorus fertilizer can increase crop yields, improve crop quality, and accelerate the growth of cereal crops. It stimulates flowering and fruiting in cotton, melons, solanaceous vegetables, and fruit trees, boosting fruiting rates; it also increases sugar content in beets, sugarcane, and watermelons, as well as the oil content in rapeseed. Phosphorus is a component of protoplasm in plants, playing a crucial role in cell growth and proliferation. Additionally, phosphorus participates in photosynthesis, the utilization of sugars and starches, and the energy transfer processes in plant life cycles. Phosphorus fertilizer further promotes root development during the seedling stage and hastens plant maturation. When plants bear fruit, phosphorus is transported in large quantities to the seeds, resulting in plumper grains.
Long-lasting slow release: Microorganisms decompose gradually, providing sustained fertilizer effectiveness, ideal for long-term crops.
Soil improvement: Increase organic matter, promote the formation of granular structure, and alleviate compaction.
Eco-friendly: Reduces phosphorus fixation, lowers leaching risks, and is more environmentally friendly.
Promote energy conversion and genetic material synthesis: Phosphorus is the core component of ATP, and a phosphorus deficiency is like “having food but being unable to cook”.
Promote flower bud differentiation and formation: Applying phosphorus before the physiological differentiation stage of flower buds can provide sufficient energy and material foundation for their formation.
Promote flowering and fruit retention, enhance fruit setting rate: Phosphorus facilitates pollen tube elongation, enabling pollen to reach the ovary more swiftly and smoothly for fertilization.
Promote root development and enhance stress resistance: Phosphorus stimulates root growth, forming a robust and extensive root system network.
Phosphorus fertilizers have long residual effects, allowing for infrequent applications over several years while also reducing soil phosphorus fixation capacity and maintaining a certain level of available phosphorus in the soil solution. Additionally, phosphorus fertilizers can enhance soil cation exchange capacity and improve soil physical properties.
Proper fertilization can enhance photosynthesis and increase organic nutrients; regulate metabolism and coordinate crop growth; improve soil conditions to meet the needs of plant development.
Stratum + seed fertilizer yields better results
Layered application: For plots with severe phosphorus deficiency, apply in two layers. For example, for grain crops, use 35-40 kg of calcium superphosphate per mu, mixing it with farmyard manure and plowing it into the deep layer, then scatter 15-20 kg on the surface layer and sow immediately. The shallow layer supplies nutrients during the seedling stage, while the deep layer supports mid-to-late growth stages.
Seed dressing with fertilizers: The seedling stage is a critical period for phosphorus nutrition, especially for crops with small seeds and low phosphorus reserves, such as rapeseed, tomatoes, and millet, where mixing with water-soluble phosphorus fertilizers yields significant results.
Tomatoes: Require the most potassium, followed by nitrogen, with relatively less phosphorus. During seedling cultivation, the nitrogen, phosphorus, and potassium ratio should be 1:2:2, while phosphorus nutrition should be increased during the fruiting stage.
Cucumber: The highest potassium requirement occurs during the entire growth period, followed by nitrogen. Nitrogen uptake increases sharply within the first 30 days after transplanting, while phosphorus absorption surges during the reproductive growth stage.
Fruit trees: Phosphorus serves as the "energy engine" and "genetic code" from flowering to fruiting. Supplementing phosphorus before the flower bud differentiation stage can significantly enhance both the quantity and quality of flowering.
The period before flowering is the critical phase for flower buds to "make a final push," during which both "underground drenching + foliar spraying" should be implemented simultaneously, so our liquid organic phosphorus fertilizer is the best choice.
Leaves: Smaller, dark green or bronze in color, with purplish-red spots or streaks on the leaf margins or tips of older leaves.
Branches: Weak, with few branches, and late sprouting in spring.
Flowers and Fruits: Few flower buds, delayed flowering, low fruit setting rate, small fruits, poor color, sour taste, and delayed ripening.
The typical symptoms of phosphorus deficiency in crops are slow growth, dark green or purple red leaves, purple red stems, and symptoms of old leaves appearing first. The specific manifestations vary depending on the crop:
Rice: slow growth after greening, short stature of plants, no or delayed tillering; The leaf shape is narrow, the leaf color is dark green and aged, the old roots turn yellow, and the new roots are few and slender; The ears are small and the grains are few, resulting in a decrease in thousand grain weight.
Wheat: The seedlings grow slowly, the root system develops poorly, tillers decrease, the stem is slender, and the base of the stem is purple. The most obvious feature is that the leaf tips and edges are purple red, while other parts are dark green. The ears have fewer small grains, and the thousand grain weight is significantly reduced.
Corn: Slow growth during the seedling stage, with more obvious symptoms at the 5-leaf stage. The leaves are purple red, the leaf tips are purple, the leaf edges are curved, the stem base is purple, the corn cob is short and small, curved, premature baldness occurs, and most seeds are not full.
Cotton: The plant is short and old, with dark leaves, thin stems, and a red base. The fruit branches are few, the leaves are small, the leaf edges and petioles often appear purple red, the root system is underdeveloped, the maturity is delayed, the buds and bells are prone to fall off, and the yield and quality decrease.
Rapeseed: It is most sensitive to phosphorus deficiency and responds earliest. When severely deficient in phosphorus, the cotyledons will develop symptoms of aging and dark green thickening after unfolding, with delayed leaf emergence and small leaf area; The stem and petiole are both purple red in color, and the plant is short and unbranched; Delayed flowering of buds, incomplete grains, decreased yield, and low oil content.
Tobacco: The entire plant is clustered, with narrow and dark leaves that stand upright. The old leaves have necrotic spots and turn brown after drying up. The tobacco leaves after being roasted have a dark and dull color.
Soybeans: The leaf color darkens, appearing dark green or dark green, with small, pointed, and narrow leaves that stand upright upwards. The plant is thin and grows slowly. When severe, the stem may appear red, and if soybeans lack phosphorus after flowering, brown spots may appear on the leaves.
Potatoes: Early phosphorus deficiency affects root development and seedling growth; During the period from pregnancy to flowering, there is a lack of phosphorus, causing the leaves to shrink and turn dark green in color. In severe cases, the base leaves turn light purple, and the plant becomes stiff. The petioles, leaflets, and leaf edges face upwards and do not spread horizontally, resulting in a reduction in leaf area and a dark green color. When there is excessive phosphorus deficiency, plant growth is greatly affected, and rust marks are prone to occur inside the potato chunks.
Peanuts: The old leaves are dark green to blue-green, then turn yellow and fall off, and the stem base is red.
Tomatoes: When the seedlings are small, the lower leaves turn green purple and gradually expand towards the upper leaves. Early leaves are small and gradually lose their luster, with a purple red color on the back of the leaves. Brown spots begin to appear on the mesophyll tissue of the leaves, which then extend to the entire leaf. The leaves become stiff, and the leaf veins gradually turn purple red. The leaf clusters also turn purple red at the end. The lower leaves curl up, the leaf tips turn black brown and die, and the old leaves turn yellow. The stem is slender and rich in fiber.
Observe symptoms: Pay attention to plant growth rate, leaf color, and stem color.
Soil testing: Testing soil phosphorus content through professional institutions.
Physiological and biochemical diagnosis: detect the activity of phosphatase in the plant body, high activity may lead to phosphorus deficiency.
Reasonable application of phosphorus fertilizer: Early and concentrated application of phosphorus fertilizer. Most crops are sensitive to phosphorus deficiency in the early stages of growth, and the proportion of absorbed phosphorus to the total phosphorus requirement is also relatively large. Usually, 50% of phosphorus is absorbed before the dry matter accumulation of the plant reaches 25% of the total biomass, and the reuse rate of phosphorus in the crop body is high. Adequate absorption and accumulation of phosphorus in the early stages of growth generally prevent crop yield reduction due to phosphorus deficiency in the later stages.
Improving soil environment: increasing the application of organic fertilizers to enhance the effectiveness of soil phosphorus.
Foliar spraying: Spraying organic phosphorus fertilizer during the critical period of crop growth to quickly replenish phosphorus elements.
