目的和方法一般认为,潜育性水稻土的主要特点之一,是还原程度强,含障害物多,对早稻的生长和发育有很大影响。本试验比较潜育性水稻土和非潜育性水稻土对早稻生长和发育为害的程度,探讨不同施肥处理在潜育性水稻土上,防止早稻受害是否可能。试图通过合理施肥,改善植株的营养状况,来克服潜育性水稻土对早稻生产的为害作用。
Aims and methods It is generally considered that one of the major characteristics of a gneisonic paddy soil is that it has a strong reduction degree and contains many pests and has a great influence on the growth and development of early rice. This experiment compared the extent of the damage to the growth and development of the early rice and the potential fertility of paddy soils to prevent the damage of early rice. Attempt to fertilize and improve the nutritional status of plants to overcome the harmful effect of gneissic paddy soil on the production of early rice.
