Organic slow-release fertilizer special for rice

Abstract

The invention discloses an organic slow-release fertilizer special for rice. The organic slow-release fertilizer special for the rice is prepared from the following raw materials in parts by weight: 71 to 73 parts of peanut meal, 32 to 34 parts of corn germ meal, 5.2 to 5.4 parts of chestnut shell, 5.7 to 5.9 parts of watermelon peel, 4.1 to 4.3 parts of lychi exocarp, 7.2 to 7.4 parts of semen litchi, 2.1 to 2.3 parts of Chinese hawthorn seed, 14 to 16 parts of calcium magnesium phosphate, 19 to 21 parts of ammonium sulfate, 15 to 17 parts of potassium carbonate, 8 to 10 parts of monoammonium phosphate, 1.3 to 1.5 parts of anthurium leaf, 3.3 to 3.5 parts of myrtle tree bark, 1.6 to 1.8 parts of myrtle leaf, 0.7 to 0.9 part of fragrant plantain lily leaf, 2.6 to 2.8 parts of catalpa bark, 0.23 to 0.25 part of azospirillum brasilense, 0.17 to 0.19 part of sesbania stem nodule bacteria, and 4.5 to 4.7 parts of lignin. The organic slow-release fertilizer special for the rice provided by the invention is scientific and reasonable in formula, effective nutritional ingredients of the raw materials are integrated with one another, the sufficient absorption and utilization and the conversion of the nutritional ingredients by the rice can be promoted, the drought resistance, the insect resistance and the disease resistance of the rice are effectively enhanced, the seed setting rate of the rice is high, the grains of the rice are full, the soil can be improved, and the fertilizer efficiency is prolonged, so that the thousand seed weight and the yield of the rice are improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a special organic slow-release fertilizer for rice.

Problems solved by technology

Although the application of chemical fertilizers can meet the needs of rice growth, due to partial application, single application and repeated application of chemical fertilizers, soil compaction, soil fertility decrease, groundwater pollution, biological activity decrease, soil organic matter content decrease, and serious pests and diseases , resulting in smaller rice grains and reduced yield
