Description

technical field

[0001] The invention relates to a crop foliar fertilizer and a preparation method thereof, in particular to a foliar fertilizer containing organic silicon. Background technique

[0002] Silicon fertilizer is one of the essential nutrients for the growth and development of legumes and gramineous crops. However, due to the chemical characteristics of silicon element, most of its compounds are insoluble, so it is difficult for silicon fertilizer to be absorbed and utilized by crops. The Chinese invention patent "a silicon-containing foliar fertilizer and its preparation method" patent number ZL98121697.8 uses colloidal silicon dioxide to improve the utilization rate of silicon fertilizer by crops. Colloidal silica belongs to inorganic silicon. Although it contains soluble matter, the absorption and utilization rate of crops will still be very low, and the fertilizer effect period is short.

Examples

Embodiment Construction

[0015] 1. Preparation of silicone. Take rice husks and concentrated sulfuric acid with a concentration of more than 95% for carbonization, wherein the weight of rice husks accounts for 50-75%, and the weight of concentrated sulfuric acid accounts for 25-50%. Warm to 100°C, filter out the residue, and obtain the organosilicon filtrate.

[0016] 2. Prepare gramineous rice seedling foliar fertilizer. (weight ratio) N 15%, P 2 o 5 8%, K 2 O 15%, trace elements: calcium 0.2%, zinc 0.8%, magnesium 0.2%, iron 0.4%, boron 0.8%, molybdenum 0.1%, humic acid 5%, organic silicon 0.5%, plant growth regulator DA-6 0.5% , and the rest is water. Mix nitrogen, phosphorus, potassium fertilizer, micro-fertilizer, humic acid and plant growth regulator in proportion, add water to dissolve, and then add organosilicon filtrate to prepare the foliage fertilizer of the present invention. Dilute 400-600 times when used.

[0017] 3. Prepare soybean (legume) foliar fertilizer. N 10%, P 2 o 5 ...
