杂交中粳“六优1号”系由六千辛A与77032-1配组而成。为了摸索其栽培特性,1986年我们就该组合的播插期、施肥量、插植密度等问题做了一些试验,现将结果整理分析如下。 一、试验基本情况 试验田土质为小粉浆土,养分状况较好,有机质含量1.53%。全氮含量0.13%,速效磷10ppm,速效钾5
Japonica hybrid “Liuyou 1” is composed of Liuqinxin A and 77032-1. In order to explore the cultivation characteristics, we conducted some experiments on the combination of sowing date, fertilizer amount, planting density and other issues. The results are as follows. First, the basic situation of the experiment Experimental soil is small silt soil, nutrient status is better, organic matter content of 1.53%. Total nitrogen content of 0.13%, available phosphorus 10ppm, available potassium 5
