Symptoms of a nitrogen deficiency barley at the height of the flood season, the old leaf color is pale yellow-green, the old leaf tip is dry, and the whole leaf is withered; the stem is slender, upright, sometimes lavender, with fewer tillers, and with a small ear. In the period of tillering, jointing or booting, the leaves were dark brown and purplish, especially purple in the sheath. From the tip of the leaves to the base, the plants were thin, with fewer tillers, poor cold resistance, and susceptible to freezing. From the joint of potassium deficiency to booting, the leaves are blue-green, the old leaves turn yellow, the tips of the leaves and the leaves are yellow and scorch, the yellowing at the booting stage is more obvious, the leaves appear white, the leaves are covered, the angle between the leaves and the main stem is large. Severe heading difficulties or premature death, small grain, shrinkage. The new leaves of the four deficient manganese seedlings are covered with soft leaves, and the new leaves are chlorotic in stripes, turning from yellow-green to yellow.
The veins are still green. The leaves of the five iron deficiency were green and gradually faded upwards, and the new leaves were all yellowed.
See etiology of wheat deficiency disease.
Prevention methods (1) Preventing nitrogen deficiency Advocates the use of compost or organic fertilizer made from fermented bacteria. Seedling period of 667m2 application of ammonium bicarbonate 10-15kg, acupuncture or with water fertilizer, medium-term application of urea 3-8kg, spraying 25 urea later. Conditional application of long-term ammonium bicarbonate at the time of sowing in autumn can satisfy the requirements of conventional autumn application of base fertilizer, spring application of fertilizer and summer application of panicle fertilizer. (2) to prevent phosphorus deficiency 667m2 applied superphosphate 15-25kg, acidic soil can be applied calcium magnesium phosphate fertilizer, spraying 0.2% -0.5% potassium dihydrogen phosphate later. (3) To prevent potassium deficiency, apply 5–10 kg of potash fertilizer per 667 m2, and apply the sub-basal fertilizer or joint-fertilizer twice. Spray 0.5% KCl or 5%-10% ash extracts later. (4) to prevent the lack of manganese every 667m2 with manganese sulfate 0.5-1kg mixed into the organic fertilizer as a base fertilizer, can also be used 40-80g manganese sulfate plus a small amount of water dissolved in 10kg seeds, dried after sowing. In addition, 0.05%-0.1% manganese sulfate solution can also be sprayed during the seedling and pre-flowering stages. (5) Prevent ferrous sulfate 4-5kg from being added to iron-deficient basal fertilizer.
