Abstract
The invention relates to a rice planting method for producing ecological rice, which comprises the following steps: soaking for 1 minutes at a water temperature of 5-53 DEG C, sterilizing at normal temperature. The seedling substrate adopts rice husk and/or crushed rice husk for biological fermentation, and after fermentation, it is mixed with nutrient soil and nutrient solution; Using biological seedling strengthening agent to adjust acid and disinfect rice seedling field; During the period from transplanting to heading, water conservation irrigation is adopted, and intermittent irrigation is adopted after heading; The fertilizer adopts organic fertilizer, biological fertilizer, mineral fertilizer and a small amount of chemical fertilizer; After 7-1 days of water preparation and 2-3 days after transplanting, fry are put in to prevent weeds and pests. The method has the advantages of organic food and green food, and discards their shortcomings, which can not only maintain the high yield and quality of rice, but also optimize the environment. Using fry instead of chemical herbicides and pesticides can completely eliminate the pollution of pesticides to rivers, lakes and other water environments and their residues in food, which is of great significance to environmental protection.
Sovereignty Item
1. A planting method of rice for producing ecological rice, which comprises the following steps:
(1) the seeds are disinfected by a warm soup method, soaked for 1 minutes at a water temperature of 5-53 DEG C for disinfection, and then soaked at normal temperature for 5-7 days;
(2) Seedling raising
The seedling raising substrate adopts rice husk and/or crushed rice husk for biological fermentation, and after fermentation, it is mixed with nutrient soil and nutrient solution, or adopts farmyard manure, peat or peat;
(3) acid regulation and disinfection of rice seedling field
using biological seedling strengthening agent to regulate acid and disinfect rice seedling field;
(4) Water layer management
During the period from transplanting to heading, water conservation irrigation is adopted, and intermittent irrigation is adopted after heading;
(5) Fertilization
The fertilizer is a mixture of organic fertilizer, biological fertilizer, mineral fertilizer and chemical fertilizer. On the basis of soil testing, the fertilizer is mixed as needed to achieve balanced fertilization. The fertilization time is before dry rotary tillage or water rotary tillage in rice fields, and the fertilizer amount is applied once a year, and the fertilization depth is
2 cm -12 cm;
(6) Weeds and pests control
After 7-1 days of water preparation and 2-3 days after transplanting, fry are put in.
