近年来,我国农业科技工作者和社员群众一道,坚持科学实验,探索水稻高产栽培规律,研究水稻高产群体结构、株叶形态、以及生理指标;注意改善冠层受光条件,增加干物质积累,协调器官之间、阶段之间的生长,协调源、库关系,调节颖花数,畅通物质运转,提高水稻结实率;重视选地培肥,建设高产土壤,积极推广高产良种,实行合理施肥,调控叶、蘗、穗的发育,为水稻高产栽培积累了丰富的经验,并涌现出一大批水稻高产典型。现根据各地资料报道,将我国南方稻区水稻高产纪录和主要栽培经验,综合整理如下,供参考。
In recent years, China’s agricultural scientists and technicians have adhered to scientific experiments and explored the law of high-yielding cultivation of rice, and studied the structure of high-yielding rice population, the morphology of the leaves and the physiological indices of the rice plants. Attention should be paid to improving the light-receiving conditions of the canopy, increasing the accumulation of dry matter, and coordinating Organs, between the stages of growth, coordination of source and reservoir relations, adjust the number of spikes, smooth flow of material to improve the rate of rice seed; emphasis on the selection of fertilizer, construction of high yielding soil, and actively promote high yielding varieties, the implementation of rational fertilization, regulation The development of leaves, tillers and spikes accumulated a wealth of experience in high-yield cultivation of rice and a large number of typical high-yielding rice emerged. Now according to local data reports, the rice yield in southern rice record and major cultivation experience, integrated into the following, for reference.
