Abstract

The invention relates to a special selenium-rich organic fertilizer for paddy rice, in particular to a special selenium-rich organic fertilizer for saline-alkali soil improvement paddy rice and a preparation method of the selenium-rich organic fertilizer. The organic fertilizer comprises the following components in percentage by weight: 10-20% of acid material, 10-20% of plant protein promotion material, 15-25% of selenium-rich mixed material, 10-25% of soil texture improvement material, 1-5% of biological bacterium and 20-45% of organic material. The manufactured special selenium-rich organicfertilizer for the saline-alkali soil improvement paddy rice improves the saline-alkali soil, and can increase a selenium content of the soil and promote selenium absorption of plants at the same time; the selenium-rich raw material used is prepared by activating natural minerals; the traditional selenium-rich raw material, sodium selenite, is abandoned; the influence on a degree of alkalizationof the soil is avoided; a soil environment is improved; a yield and quality of the paddy rice are increased and improved; and produced rice is high-quality selenium-rich rice.

Description

technical field [0001] The invention relates to a special selenium-rich organic fertilizer for rice, in particular to a special selenium-rich organic fertilizer for improving saline-alkali land and a preparation method thereof. Background technique [0002] Rice is one of the most important food crops in my country, its sown area accounts for 1 / 4 of the country's food crops, and its output accounts for more than half. The world-recognized golden rice planting belt is 40°-45° north latitude, and my country has an area of ​​3.8 million hm at this latitude 2 In the Songnen Plain, one of the world's three major soda saline-alkali concentrated distribution areas, so much land is difficult to use, which is a great waste of resources. What is even more worrying is that its area is still expanding, and the improvement of saline-alkali land is urgent. [0003] my country's high-quality rice planting belt is also one of the areas with the most serious selenium deficiency in my countr...
