近几年,有些农户在水稻育秧中出现了没有适合的秧田问题。由于遇春旱,原有的老秧田变成了没有水源的干板田,有的扩大了两季田,适合育秧的浅脚田种上了小春,特别是1987年严重的冬干连春旱,缺秧田的现象更为突出。在这种情况下,部分农户只有选用有水源的泥脚较深或者冷烂的正沟冬水田做秧田。实践证明,对这类新秧田,只要采取以提高泥温为中心,减少有毒物质危害为重点的有效技术措施,就能克服深冷烂秧田死苗或坐蔸的缺点,培育出杂交水稻带5—6个分蘖的多蘖壮秧。一、平整秧田抓三早
In recent years, some farmers appeared to have no suitable seedling problem in rice seedling raising. Due to the spring drought, the original old seedling fields became dry planks without water, some expanded the fields of two seasons, and the shallow-footed fields suitable for raising seedlings were planted with spring, especially in 1987 with serious dry-spring drought , The phenomenon of missing seedling more prominent. Under this circumstance, some peasants only choose to use the water with deep muddy feet or cold rotten sunshine paddy fields to do seedling cultivation. Practice has proved that this type of new seedling, as long as to take to increase the mud temperature as the center, to reduce the hazardous substances as the focus of effective technical measures, you can overcome the slender rotten seedling seedlings or sit shortcomings, breed hybrid rice belt 5 -6 tillers of tiller seedling. First, the grasping catch three early seedling
