Embodiment Construction

[0052] a. Multi-cropping rotation in paddy field: After the paddy is harvested, plow deeply and return the straw to the field, and then plant green manure;

[0053] b. Seedling raising: choose "Koshihikari" rice species, soak seeds, germination, and seedling raising 20-30 days earlier than the local rice planting time, that is, start in mid-March; before sowing, the selected rice seeds are aired for 1-2 days. After that, soak in 1% lime water for 2 to 3 days, and then germinate the seeds; turn over the green manure in the seedling field before sowing, and turn over the green manure 15 to 30 days before sowing the rice according to the green manure variety;

[0054] The amount of overturned green manure is controlled at 1500-2000kg per mu, and the depth of overturning green manure is 15-20 cm. After the green manure is overturned, water should be poured in time to accelerate its decomposition and decay and improve the conversion rate of green manure.

[0055] When turning over ...

Abstract

The invention relates to a planting method for organic rice. The method mainly comprises: soaking seeds, accelerating germination, raising rice seedlings, and transplanting rice seedlings 20-30 days before local rice planting time; in field preparation, turning under green manure, base fertilizer including biogas manure, fully decomposed yard manure and / or fully decomposed cake fertilizer; 10-20 days after rice transplanting, after seedlings stand, stocking ducklings, in peak of outbreak of rice planthoppers, adding a second batch of ducklings, in a rice heading flowering period, taking back the ducklings; in fertilization aspect, in addition to using green manure cooperating with farmyard manure base fertilizer, and dressing farmyard manure, the rest using wood vinegar; in pest control aspect, using field light traps and artificially propagating parasitic wasps, alternatively spraying the wood vinegar and garlic pepper solution. The method solves problems that yield of organic rice planting is not high, rice quality is not good, and plant diseases and insect pests are severe. The method is successful in plantation of ''sticky fragrance'', ''rice fragrance'', ''beautiful fragrant sticky'', and a Japan introduced variety ''Koshihikari''.

Description

technical field [0001] The invention relates to rice cultivation, in particular to a method for growing organic rice.
