Key Technical Points for Autumn Potato Cultivation with Rice Straw Mulching (Part 2)
4. Timely early sowing. Potatoes prefer a cool climate, and the sowing period should be when the daily average temperature steadily drops below 25°C. In plain and hilly areas below 500 m in altitude, the suitable sowing period is from late August to early September; in low mountainous areas at 500-800 m in altitude, the suitable sowing period is in late August. 5. Reasonable close planting and sufficient base fertilizer. For fields with rice stubble potatoes intercropped with rapeseed, both potatoes and rapeseed are planted in wide-narrow row patterns. For potatoes, the wide row is 0.6 m, the narrow row is 0.2 m, the hill spacing is 0.22 m, and about 700

What are the technical measures for drought resistance and disaster mitigation in rice cultivation in Heilongjiang Province?
In response to the actual drought situation, the Rice Expert Guidance Group of the Ministry of Agriculture conducted in-depth research in drought-affected rice areas and proposed technical measures for scientific drought resistance and disaster mitigation to ensure increased rice production. 1. Strengthen the management and scheduling of irrigation water sources. Actively develop water sources, organize as much as possible the pumping of return flow and the use of water-lifting irrigation machinery to utilize rivers, lakes and groundwater, alleviating the contradiction of insufficient reservoir storage. For plots far from water sources, promptly dig supplemental water wells to ensure a safe water supply during severe drought seasons. Strengthen the management of existing water resources and the clearing, repair and film-mulching of main irrigation canals to prevent seepage and leakage. Scientifically regulate
