为了研究潜育性稻田合理施肥的增产效果,1982年我们在长沙县朗木梨区龙华村进行了田间试验,1983年和1984年,我们在继续进行田间小区试验的同时,又在朗木梨区龙华村和金托村进行了大面积试验示范工作。龙华村七组、三组和四组以及金托大垅,历年来水稻僵苗严重,产量很低。为了防治水稻僵苗,当地曾采用不少措施,但收效甚微。试验示范稻田成土母质是第四纪红色粘土。水稻僵苗一般都发生在潜育性稻田。这些潜育性稻田,由于土质粘重,地下水位高,排水不良,水冷泥温低,虽然有机质和全氮含量
In order to study the effect of fertilization on the fertility of paddy field, we conducted a field experiment in Longhua Village, Longmu District, Changsha County in 1982. In 1983 and 1984, while continuing the field experiment in the field, Village and the village have a large area of experimental demonstration. Longhua Village, seven groups, three groups and four groups, as well as the large nursery otter rice over the years serious stiff rice seedlings, yield is very low. In order to control the rice seedlings, many measures have been taken in the area, but with little success. Experimental demonstration rice paddy soil parent material is Quaternary red clay. Rice stiff seedlings generally occur in the fertile rice fields. Due to the stickiness of soil, high groundwater level, poor drainage and low temperature of water-cooled mud, these glenellanic paddy fields, although the organic matter and total nitrogen content
