I. Overview of rice cultivation in the field
Rice, as an important food crop in the country, has a direct impact on production and quality.

The programme aims to provide a systematic rice-growing process to help farmers to grow more efficiently and economically。
Preparation for cultivation
Adequate preparation is needed to ensure that rice is growing in a suitable environment before it is officially seeded。
(i) choice of varieties
1. Selection of highly pathogenic and productive rice varieties according to local climatic conditions。
Considering the reproductive period of the varieties (e. G., early, medium and late rice), select the varieties that match the local planting season。
Example: the yangtze river basin may choose mixed rice varieties such as “two plus 638”。
(ii) soil preparation
1. Deep soils: tillage can reach depths of 20-30 cm, break the plough floor and improve soil aerobics。
2. Fashion-based fertilizer: 2,000 - 3,000 kg of decomposition organic fertilizer per acre, combined with 50 - 80 kg of compound fertilization。
3. Reconciliation ph: rice suitable for ph range 5. 5-7. 0 and acid soils suitable for lime application。
(iii) seed treatment
1. Scrutinizing seeds: removing broken, moldy seeds and ensuring that they are more than 98 per cent pure。
2. Sterilization of impregnated species: planting of more than 50% of the filamentable powder to prevent the disease of the seedlings。
Drumbing: using a “two-part sprouts” method, seed germinates over 90 per cent。
Iii. Field management
Rice needs to be carefully managed during its growth to ensure that it is sufficiency and pests are controlled。
(i) plug-in
1. Plug-in time: usually before the winter of late rice or when early spring temperatures stabilize。
2. Plug-in density: the number of plug-in plants per acre is controlled at 18-22,000
