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

Degradable-film controlled-release fertilizer for rice successfully developed in Hunan Province
The Soil and Fertilizer Institute of Hunan Province has developed a degradable-film controlled-release fertilizer for rice that can be widely applied in rice-growing regions of China with no side effects. Using natural and semi-natural polymer materials as the main coating components and adopting a self-developed new fluidized dual-spray-bed coating process, the Soil and Fertilizer Institute of Hunan Province developed a degradable-film controlled-release fertilizer whose nutrient release can be artificially controlled within 30 to 330 days. This controlled-release fertilizer is non-toxic, completely degrades within 2 years after being applied to the soil with no residue, and can reduce fertilizer pollution of the atmosphere, soil, water bodies and other environments.

How is the rice variety Feiyou 600?
Feiyou 600 is a hybrid late indica rice variety developed by researcher Cheng Shihua and others in 1999 by crossing Feigai A with R600. This combination has medium tillering ability, large panicles with many grains, a relatively high 1000-grain weight, good yield potential, and relatively low fertilizer requirements. Its resistance to rice blast is significantly better than that of the control, its grain quality is slightly better than that of the control Shanyou 63, and its seed production yield is relatively high. It is suitable for single-season rice cultivation in Zhejiang Province, and in southern Zhejiang it can be grown as continuous late rice. In cultivation, attention should be paid to preventing lodging and controlling bacterial leaf blight. In the 2001 and 2002 Zhejiang Province single-season hybrid indica rice regional trials, the two-year
