Organic rice refers to the fact that in the original ecological environment, rice is not applied with chemical fertilizers or pesticides from breeding to field cultivation, but all methods of combining microbes, plants and animal control are used to comprehensively control pests and diseases. Therefore, Xiaobian talks about organic rice variety selection, fertilizer management, and plant protection technology, as follows.
First, the variety selection
When selecting varieties, we must pay attention to the quality of the varieties, and also consider the climate and soil conditions of the cultivated land. Today, the varieties with high quality and adaptability are CY-6, 97-1, Yu 5, Nikko and Koshihikari.
Second, fertilizer management
1. In the process of organic rice production, no chemical fertilizer is applied, and only organic and biological fertilizers are used.
2. Base fertilizer: 500 kg of fermented manure fermented fertilizer per acre or 200 kg of fermented composted cake fertilizer.
3, top dressing: In the real growth process of organic rice, the new Baojia total 4 liters per acre of land. In the beginning of the tillering period, the middle of the field, the flowering period (the leaf age is 3.5), and the flower saving period (the leaf age is 1.5), each new mu of land is sprayed with 0.75 liters of Xinbaojia, and at the beginning of the earing stage, the new Baojia 1 liter is sprayed per acre. .
Third, plant protection technology
1. Chemical pesticides and hormones are not used in the growth of organic rice, but some non-polluting biogenic pesticides, botanical pesticides and mineral-derived pesticides can be used appropriately to control the occurrence of pests and diseases.
2. Pest control: use insect-resistant and disease-resistant varieties; rational close planting to prevent pests and diseases caused by excessive planting density; scientific fertilization to prevent excessive fertilization of rice and prosperous diseases caused by pests and diseases; Source" pesticide control.
3, grass damage prevention: early in the field to lure grass; artificial weeding; use fully decomposed organic fertilizer; scientifically arrange plant spacing, and promote its closure and grass.
Fourth, organic rice cultivation requirements
1. First of all, we must cultivate strong sputum: we must apply enough fertilizer at the seedling stage, and the amount of grain per acre is controlled below 40 kg.
2. Appropriately increase the density of transplanting: When transplanting organic rice, it is necessary to increase the number of points, increase the seedlings, and maintain the full ear. The number of organic rice transplanting points is 20% higher than that of conventional rice.
3. Establish a nursery spot, conduct regular investigations, and spray Xinbaojia within the prescribed growth period.
4. The spraying time of Xinbaojia is uniformly applied after 4 o'clock. If it rains 6 hours after spraying, it should be sprayed again.
5, the nozzle hole should be fine, the spray should be uniform, the concentration should be moderate.
