Abstract

Rice belongs to fertilizer-loving crops. The invention provides a special base fertilizer for rice, which consists of the following components in parts by weight: 9-11 parts of urea, 8-12 parts of diammonium phosphate, 3-4 parts of potassium chloride, 1-2 parts of zinc sulfate, 1-2 parts of copper sulfate, 5-6 parts of calcium magnesium silicate, 0.1-0.25 part of molybdenum-containing slag, 1-2 parts of manganese-containing steelmaking slag, 20-35 parts of animal manure, 5-7 parts of bean pulp, 10-15 parts of biochar and 20-35 parts of pond mud. Compared with the prior art, the invention has the beneficial effects of: the contents of N, P and K elements are reasonably proportioned according to the nutritional requirements of rice; the molybdenum-containing slag and steelmaking furnace slagare used to supplement molybdenum, iron and manganese, so that the price is low, the waste is utilized, and the environment is protected; biochar is added to improve the moisture retention and looseness of the land; animal manure, soybean meal and pond mud organic fertilizer are added, the special base fertilizer has more comprehensive nutrition and longer application time of fertilizer, is conducive to reducing the use of chemical fertilizer, improving soil performance and making soil difficult to harden, acidify and salinize.

Description

technical field [0001] The invention belongs to the field of agricultural chemical fertilizers, and in particular relates to a special base fertilizer for rice. Background technique [0002] Rice is a fertilizer-loving crop. It must absorb a variety of nutrients from the soil to grow normally. These nutrients include nitrogen, phosphorus, potassium, silicon, magnesium, calcium, sulfur, iron, zinc, manganese, boron, copper, molybdenum, etc. , Relying solely on soil supply cannot meet the needs of its growth and development, and rice will suffer from poor growth and development due to lack of nutrients, resulting in reduced yield. [0003] Zinc promotes the photosynthetic effect of chlorophyll, is a catalyst for enzyme reactions, and promotes respiration and protein starch synthesis. Zinc deficiency will cause the midrib of rice new leaves and the bases of both sides of the leaves to chlorotic and yellow, and then gradually turn into brown-red stripes In severe cases, the lea...
