Embodiment 1

[0028] A foliar fertilizer for increasing calcium content in rice grains, comprising 100 g of calcium humate, 5 g of isoamyl acetate, and 895 g of water. Its preparation method comprises the following steps:

[0029] Preparation of calcium humate: crush 10kg of peanut stalks, mix them with 0.3kg of sepiolite powder and 1.5kg of lime based on the quality of the stalks, and mix with 0.1kg of EM bacteria solution, and adjust the C / N mass ratio to 30 with urea , mix well, adjust the water content to about 60wt%, and culture it under constant temperature and ventilation for 30 days under the condition of 30°C to obtain the decomposed product; air-dry the decomposed product, mix it with the extractant, calculate the decomposed product after air-drying, and extract The consumption of agent is 8mL / g, wherein the concentration of potassium citrate in the extractant is 0.03mol / L, the concentration of potassium hydroxide is 0.2mol / L, shakes 3h, leaves standstill 16h, then adds saturated ...

Embodiment 2

[0032] A foliar fertilizer for increasing calcium content in rice grains, comprising 150 g of calcium humate, 1 g of isoamyl acetate, and 849 g of water. Its preparation method comprises the following steps:

[0033] Preparation of calcium humate: crush 10kg of peanut stalks, mix them with 0.8kg of sepiolite powder and 1kg of lime based on the quality of the stalks, and mix with 0.2kg of EM bacteria liquid, adjust the C / N mass ratio to 20 with urea, Mix well, adjust the water content to about 70wt%, and cultivate at 30°C for 40 days with constant temperature and ventilation to obtain the decomposed product; air-dry the decomposed product, mix it with the extractant, and calculate the decomposed product after air drying, the extractant The dosage is 3mL / g, wherein the concentration of potassium maleate in the extractant is 0.08mol / L, the concentration of potassium hydroxide is 0.1mol / L, shaking for 12h, standing for 20h, then adding saturated sodium sulfate solution, the The a...

Embodiment 3

[0036] A foliar fertilizer for increasing calcium content in rice grains, comprising 120 g of calcium humate, 3 g of isoamyl acetate, and 877 g of water. Its preparation method comprises the following steps:

[0037] Preparation of calcium humate: crush 10kg of peanut stalks, and mix them with 0.5kg of sepiolite powder and 1.2kg of lime based on the quality of the stalks, 0.15kg of EM bacteria solution, and adjust the C / N mass ratio to 25 with urea , mix well, adjust the water content to about 65wt%, and culture it under constant temperature and ventilation for 35 days under the condition of 28°C to obtain the decomposed product; air-dry the decomposed product, mix it with the extractant, calculate the decomposed product after air-drying, and extract The consumption of agent is 5mL / g, wherein the concentration of potassium malate in the extractant is 0.05mol / L, the concentration of potassium hydroxide is 0.15mol / L, shakes 8h, leaves standstill 18h, then adds saturated sodium s...

Abstract

The invention belongs to the technical field of agricultural fertilizer and in particular relates to foliar fertilizer capable of improving calcium content in rice grains as well as a preparation method and application thereof. Effective components of the foliar fertilizer are prepared from calcium humate and isoamyl acetate; the foliar fertilizer is sprayed at a tillering stage and a booting stage of rice according to growth characteristics of the rice and the number of times of spraying is reduced; the isoamyl acetate reacts with wax layers on surfaces of leaves to accelerate the absorptionof the rice on the calcium humate; meanwhile, the plant absorption and utilization rate of the calcium humate in the foliar fertilizer is improved and requirements on calcium in a rice growth processare met; the calcium content in the rice grains is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a foliar fertilizer for increasing the calcium content in rice grains, a preparation method and application thereof. Background technique [0002] Calcium is one of the important components of human bones. The content of calcium in the human body accounts for about 2% of the total weight of the human body. The lack of calcium will seriously affect the health of the human body; in addition, calcium also affects the synthesis of enzymes, which has a great impact on the immunity of the human body. Impact. With age, the body's calcium loss continues, leading to many diseases. In order to supplement calcium, people generally choose to buy inorganic calcium tablets from pharmacies, but the absorption of calcium is affected by many factors. Although inorganic calcium tablets have high calcium content, their absorption rate is often low, or even cannot be ab...
