水葫芦堆制的营养土对培育机插水稻秧苗的影响

Effect of Nutritional Soil from Hyacinth Compost on Cultivation of Mechanically-transplanted Rice Seedling

将水葫芦堆制的营养土与细土按不同的体积比例混匀后作为床土进行水稻育苗试验,从秧苗株高、根长、根数、床土温度、床土重量等方面研究了营养土对培育机插水稻秧苗的影响。试验结果表明:营养土体积比例为80%的床土的育苗效果最好,其培育出的水稻苗根系发达、根系盘结、苗壮,符合机插水稻秧苗的要求,且其床土重量明显比纯细土的床土要轻。

The nutritional soil from hyacinth compost was mixed with fine soil in different volume proportions, it was used as bed soil for the cultivation of rice seedlings, and the effect of the nutritional soil on the cultivation of mechanically - transplanted rice seed- lings was studied from the aspects of seedling height, root length, root number, bed soil temperature and bed soil weight. The results indicated that the bed soil with 80% nutritional soil in volume had the best seedling - cultivating effect, the bred rice seedlings was strong with developed and intertwined root system, and they were correspond with the demand of mechanical transplanting for rice seed- lings. Meantime, the weight of the bed soil with 80% nutritional soil in volume was significantly lighter than that of the bed soil of the oure fine soil.
