Last Updated: 2024/11/13, The following points should be mastered in upland rice cultivation: (1) the suitable sowing date should be selected according to the characteristics of varieties. It is generally the same time as the local early and medium rice. (2) the land with deep plough layer and good water retention should be selected. It is not suitable to plant upland rice in mountainous areas with large slope and high content of coarse sand in plough layer. (3) Deep ploughing and finishing, applying sufficient base fertilizer. The plough layer is above 15cm, and the width of the bed is about 1 meter. Per mu strip or hole application of base fertilizer phosphate fertilizer 50 kg, potash fertilizer 10 kg, farm fertilizer 500 kg. (4) direct seeding or seedling transplanting.

The following points should be mastered in upland rice cultivation:

The main results are as follows: (1) the suitable sowing date is selected according to the characteristics of the variety. It is generally the same time as the local early and medium rice.

(2) the land with deep plough layer and good water retention should be selected. It is not suitable to plant upland rice in mountainous areas with large slope and high content of coarse sand in plough layer.

(3) Deep ploughing and finishing, applying sufficient base fertilizer. The plough layer is above 15cm, and the width of the bed is about 1 meter. Per mu strip or hole application of base fertilizer phosphate fertilizer 50 kg, potash fertilizer 10 kg, farm fertilizer 500 kg.

(4) direct seeding or seedling transplanting. Direct seeding can be strip sowing or hole sowing, with a sowing amount of 6-8 kg per mu. After seed soaking and accelerating germination, mix with dry nursery nanny or carbofuran, mix and sow. The strip distance is about 28cm and the acupoint distance is 13 × 25cm. Sow about 5 seeds in each hole. Seedling transplanting adopts dry cultivation and transplanting with soil.

(5) ploughing and topdressing. The seedlings were replenished within 7 days after emergence. After 7 days, 25 kg of ammonium bicarbonate and 25 kg of excess calcium were applied per mu. Within 15 days, the combination of weeding and watching seedlings and then topdressing about 5 kg of urea as tiller fertilizer.

(6) 300mg/L paclobutrazol was sprayed once at jointing stage.

(7) timely prevention and control of diseases, pests and rodents. Pay attention to the prevention of rats and mole crickets in the seedling stage. Pay attention to the prevention of leaf blast and borer at tillering stage. In case of continuous overcast and rain at booting stage, attention should be paid to the prevention and control of sheath blight. Attention should be paid to the prevention of rodents, birds and animals during heading and filling period.

(8) in drought-prone mountainous areas, attention should be paid to prevent extreme drought at the stages of booting, heading and grain filling.
