Problems solved by technology

At present, there is an extremely unreasonable phenomenon in the application of chemical fertilizers in my country. The problem of low fertilizer utilization rate has been restricting agricultural development and farmers' income. For example, the utilization rate of nitrogen fertilizer is currently only 30-40%, and the fertilizer effect period is only about 50 days. Therefore, Mainly used as top dressing
Compound fertilizer can only be used as basal fertilizer due to technological problems, nitrogen content should not be too high, low nitrogen utilization rate and short fertilizer effect, and nitrogen fertilizer should be topdressed during the crop growth period. The way is lost in the environment, causing pollution to the environment, but also increasing the cost of agricultural production and the trouble and labor intensity caused by topdressing
[0003] Tomatoes need less fertilizer in the early growth stage and a sharp increase in the peak period; in terms of the various fertilizers required, it focuses on nitrogen fertilizers in the early growth stage, potassium fertilizers in the later stage, and phosphorus fertilizers throughout the growth period; the application of ordinary fertilizers requires tomato growth. During the period, topdressing was carried out many times, and these fertilizer requirements of tomatoes could not be well satisfied.

Abstract

The invention discloses a long-acting and slow-release blended fertilizer special for tomatoes, and relates to the technical field of agriculture. The long-acting and slow-release blended fertilizer special for the tomatoes contains the following components in parts by weight: 70-150 parts of nitrogen fertilizer, 15-25 parts of phosphorus fertilizer, 120-250 parts of potassium fertilizer, 3-8 parts of humic acid, 5-8 parts of long-acting compound fertilizer additive and 5-8 parts of trace element fertilizer, wherein the long-acting and slow-release additive consists of a nitrification inhibitor, a phosphate-solubilizing factor, hydroquinone and a rare-earth complex. The effective period of the blended fertilizer is longer than that of a common fertilizer, so that waste of the fertilizer is avoided, the fertilizing frequency is reduced, the production cost is reduced, the trouble and labor intensity brought by top dressing are reduced, and the yield and quality of the tomatoes can also be improved.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a special blended fertilizer for long-acting slow-release tomato. Background technique [0002] Fertilizer is the food of crops and an important basis for agricultural development. It is very obvious for improving the yield of crops. At present, there is an extremely unreasonable phenomenon in the application of chemical fertilizers in my country. The problem of low fertilizer utilization rate has been restricting agricultural development and farmers' income. For example, the utilization rate of nitrogen fertilizer is currently only 30-40%, and the fertilizer effect period is only about 50 days. Therefore, It is mainly used as top dressing. Compound fertilizer can only be used as basal fertilizer due to technological problems, nitrogen content should not be too high, low nitrogen utilization rate and short fertilizer effect, and nitrogen fertilizer should be topdressed during...
