Abstract

The invention discloses a single-purpose fertilizer of rice dry seedling, which is characterized by the following: allocating mass percent with 30-50% nitrogen fertilizer, 15-45% phosphate fertilizer, 10-32% potash fertilizer, 6-12% sulfur, 0. 01-0. 02% carbofuran and 0. 1-0. 2% multiple-effect azoles; choosing the nitrogen fertilizer as one or mixture from ammonia sulfate or ammonii chloridum; choosing the phosphate fertilizer as one or mixture from monoammonium phosphate, diammonium phosphate and super phosphate; choosing the potash fertilizer as potassium sulfate; setting the effective total nutrient at 25-50%; setting nitrogen (N) at 10-22%, phosphorus pentoxide (P2O5) at 7-20% and potassium oxide (K2O) at 5-16%. This invention possesses good soil adjusting acid function, which can prevent and cure major insect damage effectively.

Description

technical field [0001] The special fertilizer for dry rice seedlings of the invention relates to a fertilizer, in particular to a special fertilizer for rice dry seedling bed application, also known as "dry seedling green". Background technique [0002] Dry rice seedling raising is an advanced agricultural technology widely promoted in my country in the past ten years, and it has a significant effect on increasing production and reducing costs. The soil and fertilizer requirements for dry rice seedling raising are very different from those for water seedlings, and it is difficult for farmers to master it, which affects the promotion of dry seedling raising technology to a certain extent. Therefore, at present, farmers are in urgent need of a kind of special fertilizer suitable for the rice dry-raised seedling bed application. Contents of the invention [0003] The object of the present invention is to provide a special fertilizer for dry rice seedlings aimed at the above ...
