Detailed Explanation of Key Cultivation Techniques for Upland Rice in Spring in Both Northern and Southern Regions
I. Early-Stage Management Techniques for Early Rice Production in the South China Rice Region Currently, it is necessary to focus on drought resistance and protecting spring plowing, and to seize the opportunity for transplanting and planting. In the southern region, early rice should be transplanted around Qingming; in the central region, around Guyu; and in the northern region, before "May Day." The following technical measures should be mainly adopted: 1. Apply sufficient basal fertilizer and transplant sufficient seedlings, and apply tillering fertilizer early and heavily. On the basis of applying good seedling-departure fertilizer to the seedling field, apply 30 kg of ordinary superphosphate, 7.5 kg of potassium chloride, and 25 kg of ammonium bicarbonate per mu as basal fertilizer. Where conditions permit, apply 1000-1500 kg of high-quality farmyard manure per mu. Throw or transplant 21,000-25,000 hills per mu; for hybrid rice, two seedlings per hill (two grains), and for conventional rice, 4-6 seedlings per hill. 5-7 days after throwing or transplanting, apply 5-6 kg of urea per mu as tillering-promoting fertilizer; 12-15 days after throwing or transplanting, apply about 7.5 kg of urea and 7.5-10 kg of potassium chloride per mu, or 12.5-15 kg of compound fertilizer per mu as strong-tillering fertilizer.

How does the Super Dry Rice 1 variety perform?
Super Dry Rice 1 is a new super-high-yield dry rice variety bred by the China National Rice Research Institute. Results from plantings in Hangzhou and Hainan show that this dry rice variety has strong stress resistance, high and stable yield, and above-average grain quality, with broad application prospects, especially when planted as an early crop (dry season) in Hainan and South China, where it has considerable yield-increasing potential and great value for development and promotion. The characteristics and key cultivation techniques of Super Dry Rice 1 are briefly introduced as follows: 1. Characteristics of Super Dry Rice 1. 1. Main agronomic traits. Super Dry Rice 1 demonstrated in the Hainan dry season

Super dryland rice White Pearl No. 1 is suitable for planting in the north
White Pearl No. 1 was introduced from Israel by the Mingfeng Agricultural Science Institute of Harbin City, Heilongjiang Province, and was developed through years of purification, hybridization and selection by the institute. After years of observation, summary and analysis over hundreds of days and nights at nearly a hundred trial sites in Northeast China, Northwest China and North China, each difficulty was overcome one by one, and a new high-yield dryland rice variety suitable for large-scale cultivation in the north was bred, and it is known as the super dryland rice of the north. When planted in Harbin City, Heilongjiang Province, this variety has a whole growth period of 110-125 days, is medium-short-stemmed, with a plant height of 90-95 cm, and does not lodge. It has large panicles and many grains, with an average

What are the key cultivation techniques for Super Upland Rice 1
1. Intensive and meticulous farming: The quality of plowing and land preparation directly affects the uniform emergence and complete stand of upland rice, as well as the strength of the soil's water-holding capacity. Therefore, a good environment must be created for the growth and development of the underground parts of upland rice. 1.1. Deep plowing: The suitable soil tillage depth for upland rice planting is 18-20 cm, but the plowing depth must also be determined according to soil fertility and thickness. 1.2. Land preparation: The requirements for meticulous land preparation are level soil, with four-side ditches and a middle ditch, capable of both drainage and irrigation. Generally, the ditch depth is 1

Hybrid late japonica rice restorer lines successfully bred in the Yangtze River Basin
Through the efforts of experts from the Shanghai Academy of Agricultural Sciences, the "Yangtze River Basin hybrid late japonica rice restorer lines - Shenhui 254 and Shenhui No. 1" were successfully bred and utilized. This project was awarded first prize for scientific and technological progress by the Shanghai Municipal Government this year. The key to applying hybrid late japonica rice in production in the Yangtze River Basin is to breed excellent late japonica-type restorer lines. This project used intermediate materials between indica and japonica subspecies as bridge parents, introduced indica restorer genes into late japonica rice varieties, adopted convergent crossing and systematic selection, and gathered the excellent base

Introduction to the Hybrid Japonica Rice Variety Changyou No. 1
"Changyou No. 1" is a new "three-line" high-quality hybrid japonica rice variety bred in 1998 by the Changshu Agricultural Science Institute of Jiangsu Province. It passed Jiangsu provincial approval in January 2002 and national approval in November 2003 (National Approved Rice 2003068). At the same time, the male-sterile line of this combination, Wuyunjing No. 7 A, has applied for new variety protection, with the number CN20010203.6. Because this variety has the advantages of good quality, high yield, strong resistance, wide adaptability and high seed production yield, it has already been promoted and planted in the late

Super-high-yield new hybrid japonica rice variety Qiuyou Jinfeng successfully bred
The super-high-yield new hybrid japonica rice variety "Qiuyou Jinfeng", independently bred by Shanghai scientists, after 3 years of production demonstration planting, reached a per-mu yield of 801.9 kg, and has recently passed expert acceptance inspection. On December 31, 2006, a reporter learned at the Shanghai Minhang District Agricultural Science Research Institute that the cultivation of the excellent variety "Qiuyou Jinfeng" uses the genetic differences between the two parents of indica rice and japonica rice, with an excellent late japonica sterile line as the female parent, and selects excellent indica rice and excellent japonica rice restorer lines as the male parent, through "indica-japonica bridging" technology, applying
