Guiding Opinions on Rice Science Fertilization Technology in the Single-season Rice Region of the Lower Reaches of the Yangtze River in Spring 2015

Single-season rice region in the lower reaches of the Yangtze River (all in Jiangsu Province, northern Zhejiang Province)

Fertilization principle

(1) Add organic fertilizer and combine organic and inorganic.

(2) Control the total amount of nitrogen fertilizer, adjust the proportion of base fertilizer and top dressing, and reduce the amount of nitrogen fertilizer in the previous period.

(3) Deep application of base fertilizer, topdressing "with water with nitrogen".

(4) Oil (wheat) rice round for field, appropriate reduction of rice phosphate fertilizer. 2. Fertilization advice

(1) The production level is below 500 kg/mu, the nitrogen fertilizer (N) dosage is 8~10 kg/mu; the production level is 500-600 kg/mu, the nitrogen fertilizer (N) dosage is 10~12 kg/mu; the production level is 600-700 kg. /mu, nitrogen fertilizer (N) dosage 12~15 kg/mu; production level 700 kg/mu or more, nitrogen fertilizer (N) dosage 15~18 kg/mu. Phosphate fertilizer (P2O5) 5~6 kg/mu; potash fertilizer (K2O) 6~8 kg/mu.

(2) Nitrogen fertilizer base fertilizer accounts for 40%~50%, manure fertilizer accounts for 20%~30%, panicle fertilizer accounts for 20%~30%; organic fertilizer and phosphate fertilizer all base application; potassium fertilizer base fertilizer (60%~70%) and Spike fertilizer (30%~40%) was applied twice. The zinc-deficient soil is applied with 1 kg of zinc sulfate per acre; suitable base is applied with silicon fertilizer.

(3) The amount of base fertilizer can be appropriately reduced by applying organic fertilizer or planting green manure.
