Problems solved by technology

Although spraying potassium sulfate or potassium dihydrogen phosphate on the foliage can play a certain effect of promoting yellowing, but due to the characteristics of potassium sulfate or potassium dihydrogen phosphate and the lack of corresponding additives, the foliar surface of potassium sulfate or potassium dihydrogen phosphate The absorption efficiency of potassium hydrogen is low, and the yellowing effect is not significant

Abstract

The invention discloses foliar fertilizer capable of promoting layered yellowing of flue-cured tobacco and a preparation method of the foliar fertilizer. The foliar fertilizer is prepared from, in percentage by mass, 5%-10% of organic potassium, 38.3%-50% of potassium sulfate, 39.3-50% of monopotassium phosphate, 1%-1.7% of a surfactant and 2.4%-4.7% of microelements through even mixing. The foliar fertilizer can improve the absorption efficiency of foliage to potassium and phosphorous and further improve enzyme activity related to nitrogen metabolism in leaves and promote metabolic transformation of nitrogen to amino acid and protein, so that decomposition of leaf pigment is accelerated and normal layered yellowing of tobacco plants is realized.

Description

Technical field [0001] The invention belongs to the technical field of fertilizers specially used for planting flue-cured tobacco and preparation methods thereof. Background technique [0002] In the planting of flue-cured tobacco, due to factors such as excessive application of nitrogen fertilizer in pursuit of high yield, nutritional imbalance of tobacco plants, and inadequate field management, the tobacco leaves are difficult to mature in a timely manner. Such tobacco leaves have high moisture content, low dry matter content, and thick leaves. Layers fall yellow. After harvesting, it is not easy to bake. It is difficult to turn yellowing and dehydration during baking. It is difficult to synchronize the relationship between yellowing and drying. It is easy to bake and resistant to bake. It is easy to bake and black, and the quality of tobacco leaves is poor. , Which seriously affects the income of nutritious tobacco farmers. After the flue-cured tobacco leaves are extremely t...
