为了弄清小麦郑引1号亩产800—1000斤的高产规律,我所于1974—1980年,每年用该品种种丰产田3亩,并进行了有关的栽培试验。在5年的丰产栽培中,亩产为798.9—1015.0斤,平均亩产为908.1斤。现将高产的基本规律总结如下:一、争取大穗是高产的基础郑引1号是一个大穗型品种,充分发挥其每穗粒数多的优势,稳住穗数,争取粒重,是夺得高产的稳妥途径。在高产栽培条件下,郑引1号的一级分蘖数多为4个,二级分蘖数略多于6个,与多穗型小麦品种小偃5号比较,单株二级分蘖
In order to clarify the wheat yield of 800-1000 pounds per hectare of wheat yield Zheng law, I in 1974-1980, every year with the variety of high yield 3 acres of field, and carried out the relevant cultivation experiments. In five years of high yield cultivation, 798.9-1015.0 kg per mu, the average yield of 908.1 kg per mu. Now the basic law of high yield is summarized as follows: First, to win big ears is the basis for high yield Zheng Yin No. 1 is a large-spike variety, give full play to its advantages of more grains per spike, stabilize the spike number, for grain weight, is Win a productive way to secure. Under high-yielding cultivation conditions, Zheng-Yin-1 had four first-level tillers and two second-grade tillers slightly more than six. Compared with the multi-spike wheat cultivar Xiaoyan-5,
