The lack of trace elements in soybeans shows that the true leaves of spring soybeans are yellow and can yellow from the bottom, and there are parallel continuous or discontinuous iron-colored patches along the leaf veins on the compound leaves, and the chlorosis extends from the tips of the leaves to the base. Even the entire leaf is pale yellow, leaf veins are also green; leaves are small and thin, easy to fall off, stems are slender, the leaves of the plant are dark green, leaf thickness, uneven, long; when scales are severe, the veins are yellow-brown, full The leaves are yellow. Deficiency of potassium leaf yellowing, symptoms from the lower position of the upper leaf development; leaf margins began to produce chlorotic spots, expanding into blocks, plaques connected to the center of the leaf spread, and finally only the pulse around the green. Yellowing is also difficult to restore, leaves are thin and easy to fall off.
Calcium deficiency showed yellowing and brown spots, starting from the middle of the leaf and the tip of the leaf. The leaf veins were still green; the leaf margins were sagging and twisted. The leaves were small and long, and the leaves were pointed and pointed. However, the upper leaf of aluminum is light in color, and the main and branch veins are lighter; contiguous yellow spots appear between branch veins, the tips of the leaves are easy to lose green, and the color of the later maculae is deepened to light brown; some leaves are uneven, and some appear white at the center of veins. .
Control methods
(1) Increased application of organic fertilizer, application of enzyme compost of compost or perishable organic fertilizer 1000-2000kg per 667m2, can prevent soybeans from a variety of mineral element deficiency, and is also one of the important measures to increase production.
(2) Soybeans maintain soil moisture during flowering. However, the irrigation of the field should prevent large-scale series irrigation and flood irrigation to avoid loss of soil nutrients.
(3) Supplementing chemical fertilizers and trace elements in soybean-deficient soybean producing areas can prevent and control the deficiency of soybeans.
1 Applying urea 3-5kg or spraying 1% urea 50kg per 667m2 during the flowering period can prevent or correct the deficiency of soybean N deficiency.
2667m2 base application of 15-25kg superphosphate, can be used to prevent soybean phosphorus deficiency, sulfur deficiency;
3667m2 application of 5kg potassium sulfate or 80kg of ash, kiln ash potash, or the emergence of potassium deficiency after spraying 0.5% potassium sulfate solution 50kg, can prevent and treat soybean potassium deficiency;
4667m2 contains magnesium-rich lime 75kg, which can prevent calcium deficiency and magnesium deficiency in soybean;
5667m2 spray 50kg0.3% -0.5% of ferrous sulfate, can prevent iron deficiency in soybean;
6667m2 spray 50kg 0.5% manganese sulfate, zinc sulfate, ammonium molybdate, can prevent soybean deficiency, zinc, molybdenum disease;
7667m2 spray 50kg0.1% copper sulfate, can prevent soybean copper deficiency;
8667m2 applies 0.3kg boric acid or dressing with 0.1% borax to prevent the boron deficiency in soybean.
Description
Tilmicosin is a broad-spectrum semi-synthetic bactericidal macrolide antibiotic synthesized from Tylosin. It has an antibacterial spectrum that is predominantly effective against Mycoplasma, Pasteurella and Haemophilus spp. and various Gram-positive organisms such as Corynebacterium spp. It is believed to affect bacterial protein synthesis through binding to 50S ribosomal subunits. Cross-resistance between tilmicosin and other macrolide antibiotics has been observed. Following oral administration, tilmicosin is excreted mainly via the bile into the faeces, with a small proportion being excreted via the urine.
Tilmicosin Powder are used for chicken Mycoplasma infection, Pasteurella infection.Such as, air sacculitis, chronic respiratory disease.Tilmicosin
