Special fertilizer with rich selenium for grape

Abstract

The invention relates to a special fertilizer, specifically to a special fertilizer with rich selenium for grape. The fertilizer is prepared by comprising the following steps: crushing straws, then carrying out uniform mixing with wet chicken manure, corn flour and wood sawdust, and then adding rice-washing water, biological enzyme and yeast, carrying out uniform mixing, then carrying out sealing for fermentation, after fermentation, adding nitrogen fertilizer, phosphate fertilizer, potash fertilizer, chitin, selenium fertilizer and a soil conditioner, then continuously carrying out seeling for fermentation, after fermentation, and finally adding oleander liquid and carrying out uniform mixing so as to obtain the special fertilizer with rich selenium for the grape. The prepared fertilizer of the invention contains a variety of nutrients, contains a plurality of nutritional elements like nitrogen, phosphorus and potassium, is rich in more than 20 crop-needed quality elements like amino acid, humic acid, calcium, sulfur, zinc, iron and boron, exerts effects on regulating soil and balancing nutrients and is a novel highly-effective green fertilizer with full nutriention; selected pure raw materials with high quality are rich in soil-loosening and water-holding factors, so soil becomes looser; a variety of nutrients are added, so health of the grape is further protected; and natural mineral substances and plant growth substances are added, so fertility is more durable, resistance ability of plant body is effectively regulated, diseases are alleviated, and output of the grape is increased.

Description

technical field [0001] The invention relates to a special fertilizer, in particular to a special fertilizer rich in selenium for grapes. Background technique [0002] Grapes need to absorb more nutrients in a growth cycle, not only nitrogen, phosphorus, and potassium provided by ordinary fertilizers. If there is a lack of other nutrients, they will not be able to grow normally, the plants will be thin and small, the headings will be uneven, and the pollination rate will be low. Serious Affect the yield. After the common fertilizer is applied to the cultivated land, part of it will be transpired, dissipated and lost with water, part of it will be fixed and utilized by the soil and soil microorganisms, and only part of it will be absorbed and utilized by the crops. Studies have shown that: urea, ammonium bicarbonate Utilization rate is 20% to 46%, phosphate fertilizer (diammonium, monoammonium, heavy calcium) is 10% to 25%, potash fertilizer is 45% to 60%, it can be seen that...
