Abstract

The invention relates to a nutritional composition fertilizer for paddy rice. The fertilizer consists of a seedling culturing fertilizer, a base fertilizer and a foliar fertilizer, wherein the seedling culturing fertilizer is the combination of humic acid coated urea, diammonium phosphate, zinc sulfate and boric acid; the base fertilizer is the combination of sulfur plus macromoleclar polymer coated urea, the diammonium phosphate or monoammonium phosphate and potassium chloride; and the foliar fertilizer is the combination of urea and monopotassium phosphate. The seedling culturing fertilizer is uniformly mixed into nutrient soil during the seedling culturing of the paddy rice, the base fertilizer is uniformly applied to a field in the whole layer before the transplanting of the paddy rice and the foliar fertilizer is applied separately or applied by combing the spraying of a pesticide during the growth and at the later stage of the paddy rice. The fertilizer of the invention has the advantages of meeting the nutrient requirement of the paddy rice in the whole growth period, increasing the utilization ratio of the fertilizer and increasing yield, along with convenient application and correct nutrition combination.

Description

technical field [0001] The invention relates to a set fertilizer, in particular to a special nutritional set fertilizer for rice, and belongs to the technical field of fertilizer production. Background technique [0002] Rice is one of the most important food crops in my country. The national rice planting area accounts for about 30% of the food crop area. Scientific fertilization is one of the important measures to obtain high yield of rice. The absorption of nutrients by rice has its own rules. Different growth stages absorb different amounts of various elements, and the same growth stage absorbs different nutrients. At the same time, there are problems such as loss and failure caused by fertilizer application into the soil, such as loss and fixation. Therefore, according to the nutrient absorption characteristics of rice, combined with the behavior of various nutrient elements in the soil to achieve scientific and rational application is the key to improving fertilizer u...
