Based on long-term applying zinc fertilizer with 13 years, the paper studies the character of absorption and efficacy increasing yield of wheat to zinc. After applying zinc fertilizer, the absorption of wheat is significantly increased on micronutrients zinc, the zinc content of whose grain increases 18.8%, and straw is 41.1%. The maximum of zinc absorption is in harvest time, when grain and straw separately increase 13.99 g/hm2, 23.67 g/hm2. The ratios of increasing yield are separately 4.4%, 7%and 7% amon...
