Method for producing organic rice by integrated rice-duck farming

Abstract

The invention discloses a method for producing organic rice by integrated rice-duck farming, and belongs to the technical field of compound planting and raising. The method comprises the following steps of drying seeds in the sun for 1-2 days; soaking the seeds for 20-28 hours by using clear water; washing the seeds and then soaking the seeds for 36-48 hours by using 2% of lime water; washing the seeds and accelerating germination at the temperature of 20-25 DEG C for 12-15 hours until sprouting of the seeds; sowing 15-20kg of seeds in each acre in early ten days or middle ten days of the April in a dry rice-nursery mode; keeping moisture in the soil of a rice seedling bed, preventing insects, removing weeds, preventing rice blast and damage caused by rats and keeping seedling age for 30-45 days; applying 1500-2000kg of rotted manure and 45-55kg of organic fertilizers in each acre before transplanting by 7-10 days, and feeding shallow water in fields; raking the fields and planting 15000-25000 seedlings in each acre before transplanting by 1-2 days or in the same day of transplanting; raising ducklings hatched for 8-12 days in an early raising area for 1-2 days, and then placing 12-16 ducklings in each acre of the field; feeding 45-50g of feedstuff every day in early raised 6-8 days; stopping feeding the ducks step by step and enabling the ducks to find food freely; removing the ducks from the fields in the last ten days of the August to the early ten days of the September; and harvesting rice until the rice is yellow and ripened in the early ten days or middle ten days of the September to the middle ten days or last ten days of the October. By using the method, the yield and the quality of the rice are effectively improved, the producing and feeding structure of materials is reasonable, and the popularization and application value is high.

Description

Technical field [0001] The invention belongs to the field of compound planting and breeding technology, and specifically relates to a method for producing organic rice by co-cropping duck and rice. Background technique [0002] The duck-rice co-cropping compound planting and breeding system is a compound type that fully utilizes the ecological principles of symbiosis and mutual benefit, ecological niche and food chain, with rice paddy fields as the base, rice planting as the center, and domestic ducks being raised in nets in the field. Cultivation ecosystem. This system stimulates the growth of rice through the continuous activities of ducks. The duck's droppings can be used as organic fertilizer. The ducks' trampling of field weeds and preying on pests can replace the use of herbicides and insecticides, realizing duck farming in the field. , Use ducks to protect rice, so that rice and domestic ducks can cohabit and grow. However, the duck-rice co-cropping compound breedin...

Problems solved by technology

However, the duck-rice co-cropping compound breeding system currently being carried out in various places generally lacks an adaptive technical system established based on the different growth characteristics of rice and domestic duck strains, so that the co-growth promotion of rice and domestic ducks is limited. influences
