Fertilizer special for rice

Abstract

The invention discloses a fertilizer special for rice. The fertilizer is prepared from, by weight, 11-13 parts of ammonium sulfate, 3-5 parts of ferric sulfate, 14-16 parts of potassium nitrate, 9-11 parts of calcium superphosphate, 7-9 parts of potassium chloride, 6-8 parts of horse dung, 7-9 parts of fish maw intestines, 3-5 parts of bone powder, 2-4 parts of duck feather, 6-8 parts of dammara leaves, 3-5 parts of oriental arborvitae leaves, 4-6 parts of mangnolia officinalis bark, 0.4-0.6 part of microbial strains and 0.3-0.5 part of a composite coated cementing agent. The dammara leaves, oriental arborvitae leaves and mangnolia officinalis bark achieve a quite good bacterium and insect killing function after being stir-fried, and rice planthopper insect attack can be effectively prevented; the composite coated cementing agent conducts coating processing on the fertilizer, and a good slow release effect can be achieved; multiple microbial strains are added, and after the fertilizer is applied to soil, the formed beneficial microbial strain group can effectively improve the soil structure, improve soil fertility and effectively prevent and treat bakanae disease.

Description

technical field [0001] The invention belongs to the technical field of crop fertilizers, in particular to a special fertilizer for rice. Background technique [0002] Rice, an annual aquatic herb, with erect stalks, 0.5-1.5 meters high, varying with varieties; leaf sheaths loose, glabrous; ligules lanceolate, 10-25 mm long, with 2 leaf sheaths extending under the base on both sides Auricles with sickle-shaped stems; leaves linear-lanceolate, about 40 cm long, about 1 cm wide, glabrous, rough; large and sparse panicles, about 30 cm long, many branches, rough edges, mature stage Curved downward; spikelets contain 1 mature flower, both sides are very compressed, oblong-ovate to elliptic, about 10mm long, 2-4mm wide; glumes are very small, only a half-moon is left at the tip of spikelet peduncle Shaped traces, 2 degenerated lemmas, cone-like, 2-4mm long; both sides of the pregnant lemmas are thick, with 5 veins, the midrib is ridged, and the surface has small lattice-like papil...

AI Technical Summary

Problems solved by technology

[0003] In the process of rice planting, the growth of rice is closely related to the fertilizers used. If the fertilizer nutrients used are unbalanced, it will not only lead to slow growth and malnutrition of rice, but also lead to poor disease resistance and insect resistance; The duration of fertilizer effect is short, and fertilizer nutrients are easy to lose, which will not only increase the planting cost of growers, but also reduce the yield of rice and reduce the economic income of growers
