Rice cultivation in cold regions requires water-saving irrigation, selection of improved varieties, making the most of accumulated temperature, and growing strong seedlings
Heilongjiang Province is located in a high-cold region, where heat and water resources are relatively scarce, annual atmospheric precipitation is extremely unevenly distributed, spring is windy with little rain, and drought is quite severe. The author discusses how to achieve water-saving, high-quality, and high-yield rice cultivation in cold regions. 1. Selecting excellent varieties is the prerequisite for ensuring high-quality and high-yield rice. The varieties that rice farmers plant directly affect the quality and yield of rice. Therefore, in production, varieties with a suitable maturity period, excellent quality, stable and high yield, and strong stress resistance should be selected. First, select varieties that have passed national approval, been named, and promoted, which can ensure relatively stable rice traits, steady and rising yields, and safe and reliable use; second, introduce varieties with suitable maturity periods according to different accumulated temperature zones, and never introduce varieties across zones; third, pay attention to seed quality, and select first-grade improved seeds with a purity above 98%, a germination rate above 90%, and a moisture content no higher than 14% for production use; fourth, purchase seeds from nationally certified seed companies, research institutes, and agricultural colleges, and eliminate blind planting; fifth, in actual planting, unify varieties as much as possible, plant in contiguous fields, form scale, and achieve industrialized planting.

Detailed Explanation of a Reference Fertilization Model for High-Yield Rice
The soil-testing formula fertilization model for a rice yield of 450-550 kg per mu is as follows: (1) Total fertilizer amount and ratio The nitrogen, phosphorus and potassium ratio should be about 1:0.5:0.9, and the total amounts should be approximately: nitrogen 10-13 kg, phosphorus pentoxide 5-7 kg, potassium oxide 8-12 kg. (2) Fertilization plan 1. Basal fertilizer: (1) Organic fertilizer: generally for early rice, apply 1000-2000 kg of fresh green manure per mu, or 500-1000 kg of barnyard manure, or commercial organic

Several foreign methods of dry rice cultivation can be used for reference.
Hole planting method for dry rice cultivation. This new method was invented by the Tice Farm in New Orleans, USA. Specific operation: on moist no-till land, use a small hole-punching seeder (machine) to punch a hole about 3cm in diameter and 13-15cm deep in the soil. While punching the hole, immediately sow 1-2 rice seeds, then cover the hole with soil and fertilizer, and fill the hole with water while keeping the soil around the hole only moist. Under normal circumstances, no water needs to be given within 40 days after sowing, so that the rice roots grow deep and have a strong root system, which can effectively
