Sugar alcohol chelated calcium fertilizer special for peanuts and preparation method of sugar alcohol chelated calcium fertilizer

Abstract

The invention discloses a special sugar alcohol chelated calcium fertilizer for peanuts and a preparation method thereof, and the special sugar alcohol chelated calcium fertilizer is prepared from the following raw materials in parts by weight: 20-45 parts of softened water, 10-50 parts of sugar alcohol, 25-70 parts of a calcium fertilizer, 1-5 parts of an auxiliary agent, 0.2-0.5 part of a surfactant, 0.01-1 part of a nutrition enhancer and 0.1-0.5 part of a preservative. Sequentially weighing the raw materials in parts by weight for later use; adding softened water and sugar alcohol into the reaction kettle, keeping the constant temperature of 60-70 DEG C, and continuously stirring until the solution is uniform and clear; and keeping the temperature, sequentially adding a calcium fertilizer and an auxiliary agent into the clarified solution, continuously stirring, adding a surfactant after the liquid is clarified, setting the stirring speed to be 150-200 revolutions per minute, chelating for 30-60 minutes, cooling, adding a nutrition enhancer and a preservative, and continuously stirring until the solution is clarified, thereby obtaining the special sugar alcohol chelated calcium fertilizer for peanuts. The fertilizer is simple in preparation method, relatively low in cost and simple in production process, the photosynthesis and carbon and nitrogen metabolism capability of peanuts in the key growth period are improved, the pod character of the peanuts can be obviously improved, and finally the yield of the peanuts is increased by 10-30%.

Description

Technical field:

[0001] The invention relates to the technical field of agricultural production, in particular to a special sugar alcohol chelated calcium fertilizer for peanuts and a preparation method thereof. technical background:

[0002] With the improvement of my country's economic level, the structure of edible oil is undergoing adjustment. For example, during the period from 2016 to 2019, my country's demand for peanut oil increased by 20.5%, and soybean oil increased by 4.8%, far lower than the growth rate of peanut oil, while the import volume of oil crops increased in the same period. 72.2%. Therefore, improving the yield and quality of peanuts through technical means is an effective way to solve the contradiction between supply and demand of vegetable oil and ensure the safety of edible oils and fats in my country.

[0003] Calcium is one of the essential elements for plant growth, and it is the only apoplast except boron. It can combine with calmodulin to regula...
