Potassium Sorbitol Liquid Fertilizer

Abstract

The invention discloses a potassium sorbitol liquid fertilizer. The content of a potassium element in the potassium sorbitol liquid fertilizer is in a range of 300 to 440g / L. The potassium sorbitol liquid fertilizer is prepared at a temperature of 30 to 50 DEG C under the ordinary pressure by the following reaction that potassium formate and sorbitol undergo a reaction to produce potassium sorbitol. The potassium sorbitol liquid fertilizer is dissolved in water easily, can be applied by being spread on soil and / or being sprayed on leaves, is easy to be absorbed and conducted by plants, can supply fast a potassium element needed by plant growth, can prevent plant physiological diseases caused by potassium deficiency, is especially suitable for be used in a mature stage of fruits, can promote fruit growth through extensive supplement of a potassium element, can make fruits to have a good flavor and high sweetness, and does not cause turning green of fruits.

Description

technical field [0001] The invention relates to a crop fertilizer, in particular to a potassium sorbitol liquid fertilizer. Background technique [0002] With the continuous development of agricultural technology and agricultural economic structure in our country, crops with good economic benefits such as fruits and vegetables have been produced on a large scale, and the output has been continuously increased to meet the increase in demand. The good growth of crops depends on natural conditions such as sunlight and rain, and the nutrients such as nitrogen, phosphorus, and potassium necessary for the growth of crops also need to be replenished in time. The lack of nutrients will bring various obstacles to plant growth, such as malnutrition , illness, death, etc. In the plant growth stage, potassium as a nutrient element has the following functions: ① Potassium is an activator of many enzymes; ② Potassium can promote photosynthesis; ③ Potassium can promote protein synthesis; ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing conventional potassium fertilizers are difficult to dissolve in water and are not easily absorbed by plants, and they also contain nitrogen, phosphorus, sulfur and other elements, which will cause the phenomenon of fruit turning green and delay fruit ripening, so it is not suitable to apply at the fruit ripening stage
