The growth and function of Rice Root
After accelerating germination, the seeds sprout and take root. At first, only one root, called seed root (main root), grew from the radicle of the seed. The fibrous root that grows from the root point of the stem node is called adventitious root. There are about 5 hairy roots in coleoptile nodes and incomplete leaf nodes, 10 hairy roots in the first, second and third leaves, and about 10-20 hairy roots in the nodes above the fourth leaf. This is because the leaves increase sequentially from the bottom up, the supply of nutrients to the hairy roots increases sequentially, and the hairy roots also increase. Aboveground nodes, generally not rooting. The nutrients produced by leaves are

High-yield cultivation of two-line rice
Two-line rice has the characteristics of early growth and rapid development, smooth color conversion in the middle stage, long post-ripening period, fertilizer resistance, large panicle and many grains, better rice quality, stable and high yield and obvious advantage in yield increase compared with three-line rice. it has been popularized and applied in various areas in recent years. In practice, we have conscientiously grasped the "six changes" measures for high-yield cultivation, gave full play to the high-yield advantages of two-line rice, and achieved gratifying results. 1. Improve the technique of raising seedlings and cultivate strong seedlings according to the characteristics of small elasticity of seedling age of two-line rice. Row
