First, the morphological characteristics. When zinc is deficient in zinc, the main veins are chlorotic, and the main veins are enlarged to yellow and white along the leaf margin. Finally, the whole leaves are brown, the plants are short, the tillers are small, and the roots are slowly stretched. When zinc is mildly deficient, a small amount of brown spots appear on the tillers and the old leaves of the base; when the zinc is severely deficient, the rice bushes are dwarfed, a reddish brown, and growth is inhibited. Zinc deficiency in rice, lighter production, and heavy death.
Second, the cause. The demand for zinc in rice is very small, and it is a trace element compared with nitrogen, phosphorus and potassium. Due to the long-term single application of chemical fertilizers, combined with soil erosion, zinc deficiency in many fields is becoming more and more obvious. Therefore, it should be taken seriously.
Third, prevention and control measures. Plant green manure and apply farmyard manure. When leveling the land, care should be taken to protect the topsoil because the amount of zinc in the topsoil is more than that of the below. Add zinc sulphate-based fertilizer, the dosage is generally about 1 kg per acre. Zinc is not easy to move in the soil, so zinc fertilizer should be applied under or next to the seed, and the surface application effect is poor. When applied, it can be mixed with physiological acid fertilizer, but avoid mixing with phosphate fertilizer.
The seeds were continuously soaked for 12 hours with a 0.1-0.2% zinc sulfate solution, and the roots were washed with a 1% zinc oxide suspension, and the effect was good. Zinc fertilizer can be sprayed at the 3-leaf stage of seedlings, 3-5 days before transplanting, and transplanted 5-7 days in the field. The spraying concentration is 0.1-0.2%, and spraying on rice leaves 2-3 times, generally Eliminate zinc deficiency symptoms.
Zinc is a catalyst for the redox process in plants. It is present in an enzyme that promotes the respiration of cells. Zinc also affects the formation of chlorophyll and growth stimulating hormone.
