水稻地膜覆盖旱作栽培(简称地膜稻)是近几年引进我省的一项新兴栽培技术,经过全省各地几年的试验示范与推广,增产效果明显,经济效益显著。它具有保温、保水、保肥、疏松土壤等作用,是以稻治涝、改造中低产田、调整种植结构的开发性措施。 本试验对4个地膜稻品种寒九、寒二、双丰八、京引127等进行对比研究,试验1986年在本校进行。试验采用畦种,每畦没1小区,小区长16.7m,宽0.9m,供试品种设4个处理、3次重复、随机排列。
Dry cultivation of rice mulching (referred to as plastic film rice) is introduced in our province in recent years, a new cultivation techniques, after several years of pilot demonstration and promotion across the province, the yield increase effect is obvious, significant economic benefits. It has insulation, water conservation, fertilizer, loose soil, etc., rice is flood control, transformation of low-yielding fields, adjust the planting structure of the development measures. In this experiment, we compared the four cultivated rice varieties, Jiuxiu, Hanzhong, Shuangfeng Ba, Jingyin 127 and so on. The experiment was carried out in our school in 1986. The test uses a variety of, species, each 畦 no 1 district, cell length 16.7m, width 0.9m, the test varieties set up four treatment, three times repeated random arrangement.
