以陆两优996为材料,研究了不同种植方式对双季超级早稻陆两优996产量和品质的影响。结果表明:种植方式和管理水平对双季超级早稻产量和品质均有影响,其中高产管理条件下水稻产量高于常规管理,不同种植方式下水稻产量以人工移栽和翻耕抛秧产量较高,机插秧次之,免耕抛秧、机直播、撒直播较低。不同种植方式下水稻产量的高低受单位面积有效穗数影响较大。人工移栽和翻耕抛秧条件下,水稻最高茎蘖数出现的时间早,生育前中期物质生产量大,单株根系干质量大,10~20 cm深层根系所占比例大,有效穗数较多;直播条件下水稻营养生长期缩短,前期分蘖增长速度快,但分蘖下降的速度也较快,成穗率较低,有效穗少,全生育期物质生产量特别是生育前中期物质生产量较小,单株根系干质量小;机插和免耕抛秧条件下水稻前期分蘖增长慢,有效穗数不足。研究还表明,不同种植方式对稻米的垩白度、胶稠度和蛋白质含量有较大影响。 This paper studied the effects of different planting methods on the yield and quality of two-season super early rice Lu Liangyou 996 with Lu 2 you 996 as material. The results showed that: the planting methods and management level had an impact on the yield and quality of double-cropped super early rice. Among them, the yield of rice under high-yielding management was higher than that of conventional management. The yield of paddy under different planting modes was higher , Machine transplanting followed, no-toss throwing seedlings, live machine broadcast, broadcast live lower. Under different cropping patterns, the yield of rice is greatly affected by the effective panicles per unit area. Under the conditions of artificial transplanting and tillage and transplanting seedling, the highest number of tillering appeared in rice at early time, the material yield was large before midlife, the root mass per plant was large, the proportion of deep root in 10-20 cm was large, More; under the condition of direct seeding, the vegetative growth period of rice is shortened, the growth of early tillering is fast, but the tillering speed is also faster, the rate of ear formation is lower, the effective spike is less, the material production of whole growth period, especially the material production before midlife The amount of dry root per plant is small and the tillering of rice is slow and the effective panicle is insufficient under the conditions of machine-inserted and no-tillage-throwing. The study also shows that different planting methods have a great impact on the chalkiness, gel consistency and protein content of rice.
