研究钵苗机插群体结构特征及产量形成特点,探索适应稻作生产的高产、稳产栽培技术。以毯苗机插为对照,设置钵苗机插高产示范田,系统比较其生长发育各项指标。研究表明:相比传统毯苗机插,钵苗机插秧苗素质明显高于毯苗机插,发根力优势明显;移栽后分蘖发生快,成穗率高;各生育时期干物重高于毯苗机插稻;抗倒能力强,单茎抗倒力矩为51.0g/茎,较毯苗高18.9%;最终产量钵苗机插稻达11.52t/hm2,较毯苗机插高0.62t/hm2,增产5.7%。
Research mortar machine plug population structure characteristics and yield formation characteristics, to explore the production of high yield, stable yield cultivation techniques. In order to insert blanket machine as a control, set up high-yield seedlings Miao machine demonstration field, the system to compare the various indicators of growth and development. The results showed that compared with the traditional blanket machine, the quality of seedling machine was obviously higher than that of blanket machine, the rooting force had obvious advantages; the tillering occurred quickly after transplanting and the percentage of ear became higher; Carpet seedling machine inserted rice; lodging resistance, single stem anti-overturning moment of 51.0g / stem, 18.9% higher than the blanket seedlings; final output of pot seedlings machine rice up to 11.52t / hm2, blanket machine plug higher 0.62t / hm2, an increase of 5.7%.
