Potato special liquid fertilizer and its application method

Abstract

The invention provides a special liquid fertilizer for potatoes and a fertilization method thereof. 1000 ml of special liquid fertilizer for potatoes is prepared from the following raw materials in parts by weight: 90-130 parts of glutamic acid, 85-125 parts of alginic acid, 5-19 parts of manganese sulfate, 27-35 parts of chelated zinc EDTA-Zn, 15-32 parts of chelated iron EDTA-Fe, 11-21 parts of boric acid, 10-17 parts of sodium selenite and the balance of water. After the special liquid fertilizer for potatoes provided by the invention is adopted, the growth period of potatoes is advanced, the seedlings are trim and strong, the yield-increasing effect is significant and the effect of perfecting the quality of potatoes is obvious.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special liquid fertilizer for potatoes and an application method thereof. Background technique [0002] The potato industry has become the dominant industry in Gansu Province. In recent years, the province's planting area has stabilized at more than 10 million mu. However, due to farmers' lack of understanding of crop rotation and stubble in production, the planting area of ​​continuous stubble and top stubble has also increased year by year. Coupled with the long-term fertilization habits of farmers in the production process of "heavy base fertilizer, light top dressing, major medium elements, minor elements, heavy inorganic fertilizer, light organic fertilizer", the soil organic matter and trace elements in the main potato production areas have decreased year by year, resulting in The commodity and quality of potatoes are poor, and the stress resistance and t...

Problems solved by technology

Coupled with the long-term fertilization habits of farmers in the production process of "heavy base fertilizer, light top dressing, major medium elements, minor elements, heavy inorganic fertilizer, light organic fertilizer", the soil organic matter and trace elements in the main potato production areas have decreased year by year, resulting in The commodity and quality of potatoes are poor, and the stress resistance and storability of tubers are reduced, which affects the yield and value of potatoes, and ultimately directly affects the income of farmers
