Problems solved by technology

[0003] However, for organic fertilizers or organic materials fermented from livestock and poultry manure, heavy metal elements, salt, and antibiotics are often added to the feed during the feeding process of livestock and poultry, resulting in the presence of organic fertilizers or organic materials fermented from livestock and poultry manure. Heavy metal, salt and antibiotic pollution risks, if used for a long time, not only pollute the soil, but also seriously affect the safety and quality of rice

Embodiment 1

[0047] A fertilization method for organic rice production, comprising the following steps:

[0048] (1) On October 15, 2019, according to the density of 4 to 5 catties / mu, the milk vetch seeds were evenly sown in the rice field.

[0049] (2) On November 13, 2019, after the rice matured, it was mechanized harvesting, leaving 20-25 cm of stubble, and the remaining straw was crushed by a harvester to a length of 5-10 cm and evenly returned to the field. The quality of the returned straw was 550 kg / mu.

[0050] (3) After rice straw is returned to the field, ditching is mechanized. Specifically: open horizontal ditches with a distance of 3 to 4 meters in the field, the ditch width is 15 to 20 cm, and the ditch depth is 10 to 15 cm; side ditch and waist ditch are opened, and the side ditch and waist ditch are about 3 to 5 cm deeper than the horizontal ditch. Guarantee that the ditch is connected, so that the field is unobstructed due to drainage.

[0051] (4) On April 25, 2020, sh...

Embodiment 2

[0057] With embodiment 1, the difference is that step (4) milk vetch overturning amount is 2t / mu, and step (7) rapeseed cake consumption is 400kg / mu.

Embodiment 3

[0059] With embodiment 1, difference is that step (4) when milk vetch overturning amount is 3.5t / mu, step (7) rapeseed cake consumption is 300kg / mu.

Abstract

The invention belongs to the technical field of rice planting. The invention specifically relates to a rice organic production fertilizer and a fertilizer supply method for rice organic production. The organic rice production fertilizer comprises straw, green manure and cake fertilizer, the mass ratio of the straw to the green manure to the cake fertilizer is (0.8-1.83): (3-12): 1. The mass ratio of the straw, the green manure and the cake fertilizer in organic production of the rice and the specific application opportunity and application amount are limited, the three plant source organic materials including the straw, the green manure and the cake fertilizer are scientifically and reasonably combined and applied, the nutrient absorption and utilization requirements of the rice in the whole growth period are met, the high yield of the rice can be promoted, and the soil fertility can be improved.

Description

technical field [0001] The invention belongs to the technical field of rice planting. Specifically, it relates to a rice organic production fertilizer and a fertilizer supply method for rice organic production. Background technique [0002] my country is a big country of rice production and consumption, and more than 60% of the population takes rice as the staple food. The quality and safety of rice has always been the focus of people's attention. With the development of social economy and the improvement of people's living standards, organic rice production is gradually becoming one of the development directions of my country's rice industry. Organic rice production refers to a production system that does not use chemically synthesized fertilizers, pesticides, growth regulators and other substances during the entire growth period of rice, nor does it use genetically engineered organisms and their products. Apply chemical fertilizers, adopt practical agricultural, biologic...
