Abstract

The invention relates to a water-retention compound fertilizer special for pyrus ussuriensis. The compound fertilizer is formed by mixing dry compound fertilizer grains with powdered agricultural water-retention agent; the dry compound fertilizer grains are prepared from the following raw materials by weight percent: more than 65% of biological carbon organic fertilizer substrate, 15-16% of urea, 12-13% of monoammonium phosphate, 4.5-5.5% of potassium sulfate and 0.005-0.006% of trace elements; the weight of the agricultural water-retention agent is 2.0-2.2% of the weight of the dry compound fertilizer grains. The fertilizer utilizes a water fertilizer coupling principle, so that the utilization efficiency of the fertilizer and rainwater can be extremely increased, the plant stress resistance can be promoted, the yield, quality and commodity rate can be increased, the planting benefit can be obviously increased and the water-retention compound fertilizer is high in yield and efficiency, is economical and practical and is convenient.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special compound fertilizer of the water-retaining type for the skin fruit. Background technique [0002] As human beings pay more and more attention to the environment, health and sustainable use of natural resources, it is the current technological innovation of agricultural fertilizers to minimize fertilizer loss, improve fertilizer utilization, and reduce agricultural non-point source pollution while ensuring food production. It is also an important guarantee for the sustainable development of agriculture. [0003] It is a local cultivar of the Xinjiang pear system of the Rosaceae Apple subfamily. It is at the upper limit of the distribution of Pyrus plants. It has strong tree vigor, long tree age, no strict requirements on soil, dampness and cold tolerance, resistance to diseases and insect pests, and adaptability strong features. Fertilizer is a crop that requires a lot of water and fert...
