Chelating fertilizer special for potatoes

Abstract

The invention belongs to the technical field of fertilizer, relates to chelating fertilizer, and in particular to the chelating fertilizer special for potatoes, which is applied to the field of potato planting, solves the problems of poor stress resistance caused by lack of trace elements, and low commercial potato rate, high nitric nitrogen content in tubers, poor taste and soil property deterioration which are caused by a low fertilizer utilization rate, and is capable of enhancing the stress resistance, increasing the fertilizer utilization rate, increasing the yield and the commodity rate of the potatoes, increasing the taste of the tubers, achieving high efficiency and environment friendliness, realizing production and income increment of growers and further realizing sustainable development of agriculture. The chelating fertilizer is prepared from the following raw material components in parts by weight: 10 to 20 parts of sorbitol, 8 to 30 parts of high-purity water, 1 to 5 parts of calcium acetate and 30 to 60 parts of calcium nitrate. The chelating fertilizer disclosed by the invention has the advantages of good application effect, good application environment, high fertilizer utilization rate, high yield, good quality, good economic benefit and wide market prospect.

Description

Technical field: [0001] The invention belongs to the technical field of fertilizer production, and relates to a chelated fertilizer, in particular to a special chelated fertilizer for potatoes, which is applied in the field of potato planting. Background technique: [0002] Potato (Solanum tuberosum L.), belongs to the herbaceous tuber crop of Solanaceae, and the tuber is edible. It is the fourth largest food crop in the world. The potato cultivation area in my country is relatively large, accounting for 20%-25% of the world's total. It has been cultivated for more than 400 years History, throughout the country's many provinces, cities, and autonomous regions, due to the differences in latitude, altitude, geography, and climate conditions between regions, different light, temperature, moisture, and soil conditions have been formed, thus forming a suitable potato cultivation and farming system and breed types. Potato cultivation areas in my country can be divided into four cha...

Problems solved by technology

[0003] In order to overcome the defects in the prior art, the invention provides a special chelated fertilizer for potatoes, which is scientifically formulated according to the demand ratio of each nutrient element in the potato growth period, and sorbitol is used as a chelating agent to prepare a special chelated fertilizer for potatoes to solve the problem caused by the lack of Trace elements lead to poor stress resistance, low fertilizer utilization rate leads to low commercial potato rate, high content of nitrate nitrogen in tubers, poor taste and deterioration of soil properties can enhance stress resistance, improve fertilizer utilization rate, increase potato yield and commercial rate , improve the taste of tubers and are highly efficient and environmentally friendly, which can increase the production and income of growers, and then realize the sustainable development of agriculture
