Embodiment 1

[0046] The cultivation method of organic rice of the present invention comprises five steps such as fertilizing soil fertility (planting green manure), cultivating seedlings, applying fertilizer, reasonable close planting, and field management:

[0047] (1) Fertilize the soil (planting green manure); after the harvest of the previous crop of rice, on October 25, milk vetch: fine sand = 1:1 mixed application, the number of fine sand mesh is 40 mesh, and 2.5 kg of milk vetch per mu;

[0048] (2) the process of cultivating rice shoots is:

[0049] 1) Variety selection: select high-quality rice varieties Nanjing 49 and Liangyoupeijiu (Grain Institute of Jiangsu Academy of Agricultural Sciences) with good agronomic properties and strong disease resistance, suitable for local planting;

[0050] 2) Seed treatment: dry the seeds for 1 day before sowing, then soak the seeds in 1% lime water for 40 hours, then wash the seeds with clean water, and germinate the soaked seeds until the breas...

Abstract

The invention provides a cultivation method for organic rice. Green manure, rape seed cakes and a biological bacterial fertilizer are used as production fertilizer sources. Preferably, weeds and insects are killed manually. Rational close planting is adopted. The method further comprises a step of improving soil fertility, wherein green manure is applied to soil. The method further comprises a step of cultivating rice seedlings, specially comprises the steps of: selecting and treating rice seeds; and then sowing the rice seeds in a proper period. The method further comprises a step of applying a fertilizer, wherein rape seed cakes and the biological bacterial fertilizer are applied. The method further comprises a step of field management. The invention further provides related organic rice. The cultivation method for organic rice provided by the invention can better use the biological bacterial fertilizer and green manure. Soil is planted while being cultivated, so that the activity of soil is improved, the fertility of soil is improved, and the residual amount of heavy metal ions and pesticides is reduced. The cultivation method is skillful in design, simple to use, safe and environmental-friendly and low in production cost. The obtained organic rice is low in pesticide residual amount, does not harm human health, and is high in yield and good in quality, the economical benefit is increased, and the organic rice is suitable for being popularized and applied on a large scale.

Description

technical field [0001] The present invention relates to the technical field of crops, more specifically to the technical field of rice, in particular to an organic rice and a cultivation method thereof. Background technique [0002] At present, a large amount of chemical fertilizers are used in rice cultivation, resulting in uneven supply of various nutrients and extremely limited crop absorption; and most of the applied fertilizers are fixed by the soil, resulting in low fertilizer utilization efficiency. At the same time, the long-term application of a large number of chemical pesticides not only increases the amount of heavy metal ions and pesticide residues in the soil, but also seriously damages the ecological balance, causing aggravation of diseases, insect pests and weeds. These problems will not only increase production costs, but also seriously affect the yield and quality of rice, reduce economic benefits, and even threaten human health. [0003] Nowadays, biologi...
