Detailed Explanation of Key Techniques for Super-High-Yield Cultivation of Double-Season Rice in South China
(1) Sow at the right time and cultivate strong seedlings. For early rice, use dry-raised seedlings, with a seeding rate generally of 90 g/m2 and a sowing period in mid-to-late March; for late rice, use sparse sowing for strong seedlings or two-stage seedling raising, with a seed rate of about 1.0 kg per mu. (2) Ridge and bed cultivation. Bed width 3-4 m, ditch width 0.2-0.25 m, and open surrounding ditches well to facilitate water management and field operation management. (3) Wide-row close planting. The planting density is 30-40 hills/sq m, with a row spacing of about 25 cm. Generally, early rice has 3-4 seedlings per hill, and late rice is transplanted as single seedlings or double seedlings, ensuring

How is upland rice cultivated? These technical points need to be mastered
Upland rice cultivation should master the following points: (1) Select a suitable sowing period according to variety characteristics. Generally the same as the local early and middle rice. (2) Choose plots with deep soil plough layers and good water retention. Mountainous land with steep slopes, shallow plough layers and high coarse sand content is not suitable for planting upland rice. (3) Deep ploughing and fine preparation, with sufficient base fertilizer. Plough layer over 15cm, bed width about 1 m. Apply base fertilizer per mu by banding or hole application: phosphate fertilizer 50 kg, potassium fertilizer 10 kg, farmyard manure 500 kg. (4) Direct seeding or seedling raising and transplanting. Direct seeding can be drilled

New upland rice variety developed in Shandong, agronomist Xu Defang successfully breeds it
In the golden autumn season, a new upland rice variety carefully cultivated over 3 years by Xu Defang, an agronomist at the Dongying Branch of the Shandong Academy of Agricultural Sciences, has achieved a bumper harvest. According to calculations, it yields more than double that of the current upland rice variety 297, with a yield of 600-650 kg per mu, marking a breakthrough in China's upland rice breeding. Xu Defang used more than 30 ancestral lines provided by Professor Li Zichao of China Agricultural University, discovered a dwarf-stalk mutant line from the tall-stalk line 33-1, and from it selected a group of 9 lines, namely early-maturing, glutinous, early

Detailed Explanation of Main Cultivation Techniques for the New Late Japonica Rice Variety Ning 81
1. Sow at the right time and transplant at the right time. Sun the seed before sowing, soak the seed with seed-soaking agent or "402" chemical solution. For single-season late rice cultivation, the sowing period is June 5-15, with a seeding rate of 2.5-3.0 kg per mu, a seedling-bed seeding rate of about 30 kg per mu, and a seedling age of about 25 days. For continuous late-season cultivation, the sowing period is June 25-30. The seeding rate is about 3.0 kg per mu, the seedling-bed seeding rate is 25-30 kg per mu, and the seedling age is 25-30 days. For continuous late-season machine transplanting or seedling-throwing cultivation, sow around July 5
