What are the key cultivation techniques for upland rice?
Upland rice is usually cultivated directly in dry land, and is especially suited to low-lying fields. It never requires a water layer throughout its life, relying entirely on natural rainfall or, when drought reaches a certain level, supplemented with a moderate amount of irrigation. Its cultivation and management methods are similar to those of wheat. Key points of upland rice cultivation: first, ensure a full stand from a single sowing; second, control weeds in the field; third, all cultivation technical measures must be applied as a complete set. 1. Variety selection. To obtain relatively high yields from upland rice, varieties suited to dry-land cultivation must be selected. The requirements are: (1) the growth period should be moderate,

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
