With the decrease of high-quality labor in rural areas, the rising of labor cost and the development of large-scale production, direct seeding as a simplified rice planting technology was widely used continuously. Therefore, the promotion of its stable or increased yielding was of great significance in ensuring food security in this country. According to the growth characteristics of direct seeding rice in multiple cropping area of South China, a concept of growth constrained direct seeding rice was put forward. In other words, the rice emergence and seedling growth under direct seeding were significantly imitated and affected by multiple adversities, which were caused by 100% returning the previous crop straw to the field and lower quality of ploughing and sowing in short crop rotation time. And the rice later sowing date under direct seeding method than transplanting rice shortened the plant growth duration, reduced the utilization of temperature and light resources, and imitated the rice growth, as affected by the previous crop. Thus the yield of direct seeding rice was not high and instable. For now, this kind of growth constrained direct seeding rice was widely used in production and restricted the balanced production increase in large area. Therefore, the stable yield cultivation methods of growth constrained direct seeding rice were explored in this paper. The comparison experiments were carried out with a representative japonica rice variety in consideration of more panicles and more grains in Jiangsu, and the treatments of 1.2 million, 2.4 million and 3.6 million basic seedlings per hectare, under representative simplified cultivation and sowing methods on a large scale. With the basic seedlings treatments, three cultivation ways of growth constrained direct seeding rice were formed respectively, including panicles formed with more tillers, panicles formed with both stems and tillers, and panicles formed with more stems in the experiment. The characteristics of photosynthetic matter production, yield and quality of different types of rice were systematically analyzed. “The basic seedlings of rice should be increased appropriately to increase the ratio of main stem to panicle and produce more spikelets with sufficient main stem, and then the dry matter in middle and late growth duration would be produced and accumulated more and more” was tentatively believed as an effective cultivation way for stable yield, high quality and efficiency of growth constrained direct seeding rice. The key techniques of stable yield cultivation and reasonable development suggestions of growth constrained direct seeding rice were also introduced in this paper.
