Special trace element compound fertilizer for K326 flue-cured tobaccos and application of special trace element compound fertilizer

Abstract

The invention discloses a special trace element compound fertilizer for K326 flue-cured tobaccos. The special trace element compound fertilizer comprises six trace elements of molybdenum, boron, iron, zinc, copper and manganese, wherein every 1000g of the trace element compound fertilizer consists of the following trace elements by weight: 5 to 10g of molybdenum, 55 to 75g of boron, 100 to 117g of iron, 3 to 10g of zinc, 2 to 5g of copper and 37 to 76g of manganese. The special trace element compound fertilizer for the K326 flue-cured tobaccos disclosed by the invention has the following beneficial effects that: firstly, requirement characteristics of K326 on trace elements are met, and the disease resistance and a growth condition of the K326 in the field is increased; secondly, the fertilizer utilization rate is increased and the dosage of a chemical fertilizer is reduced; thirdly, the tobacco leaves are effectively promoted to mature and turn yellow, and the tobacco leaf roasting difficulty is reduced; and fourthly, economic indexes such as acre yield, output value per mu, first-class tobacco proportion and the like of the K326 are obviously improved.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special trace element compound fertilizer for K326 flue-cured tobacco and the application of the compound fertilizer. Background technique [0002] Trace elements are essential nutrients for the growth of flue-cured tobacco, and the lack of trace elements will lead to a decline in the quality of tobacco leaves, a reduction in yield or even a failure. Although trace elements are necessary, the more the better, exceeding the critical point will cause adverse effects on the tobacco plants. On the other hand, trace elements must be scientifically and rationally matched. After application, they can fully exert their respective effects on the tobacco plants and effectively improve economic indicators such as tobacco leaf yield, quality and output value. [0003] K326 flue-cured tobacco is a relatively fertilizer-resistant variety of flue-cured tobacco, and its own d...
