Embodiment 1
[0032] (1) Cultivate seedlings:
[0033] 1) Variety selection: choose Yuxiang 203, a high-quality rice variety with good agronomic properties, strong disease resistance, and suitable for planting in Southwest China;
[0034] 2) Seed treatment: first sun-dry the seeds for 1 day, then soak the seeds in 1% lime water for 2 days, and then accelerate germination;
[0035] 3) Sowing at the right time: Sowing on February 25, the sowing rate is 1 kg / mu.
[0036] (2) Fertilizer application:
[0037] It is divided into two steps: the first step is the preparation and application of decomposed farmyard manure: evenly spray a bottle of 80ml microbial fertilizer on 4000kg of farmyard manure, cover it with plastic film, make it after 21 days of treatment, and then apply decomposed farmyard manure 1000- 1500 kg / mu in the paddy field; the second step is to apply microbial fertilizer: spray 80ml / mu of microbial fertilizer in the paddy field with a water depth of less than 3cm, and transplant...

Abstract
The invention discloses an organic rice cultivation method, which comprises the following four steps of: 1) rice seedling raising, 2) fertilizer application; 3) reasonable close planting and 4) field management. The organic rice cultivation method is characterized in that the step of fertilizer application comprises the following two sub-steps of: 1) preparing and applying composted farmyard manure: evenly spraying microbial manure into farmyard manure, covering the farmyard manure with a plastic film, processing for 21 days to obtain the composted farmyard manure and then applying the composted farmyard manure in a paddy field; and 2) applying microbial manure: applying the microbial manure in the paddy field with water depth being less than 3cm and transplanting rice seedlings 15 days later after the microbial manure is applied. The organic rice cultivation method has the advantages that the heavy-metal ions and the chemical residues thereof in soil can be eliminated; the caking and the desertification of the soil can be gradually eliminated, the content of organic matters is improved, the pH (potential of hydrogen) is regulated, the granular structure is optimized and the breeding of harmful pathogenic bacteria is inhibited; the nutrients are sufficient; and a large quantity of nitrogen elements in air and various intrinsic elements in the soil are fully utilized, and low-carbon, environmental-friendly, sustainable, circular and high-efficiency agricultural economy is formed.
Description
technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to an organic rice cultivation method. Background technique [0002] A large amount of chemical fertilizers (such as ammonium bicarbonate, calcium superphosphate, compound fertilizer, potassium fertilizer, and urea) are used in rice cultivation, and the supply of various nutrients is uneven, and the absorption of crops is extremely limited; and a large part of the applied fertilizer is fixed by the soil, thus cause great waste. The soil itself contains heavy metal ions. At the same time, long-term repeated use of chemical pesticides has poisoned soil microbial strains, resulting in soil compaction, reduced productivity, increased heavy metal ions and pesticide residues, and a serious imbalance in the ecological environment. These problems will also aggravate the risk of pests and diseases However, in order to prevent and control the resulting pests and d...
