我场历年小麦播种面积200亩左右,自从1974年以来,连续四年稳产千斤以上,1977年在气候条件不利的情况下,196亩小麦获得平均亩产1,058斤的好收成。几年的实践证明,当前我们种植的太山1号,烟农685等品种,只要栽培得当,可以稳产千斤以上。我们的体会是:一、统一“三高点”小麦籽粒的产量是由单位面积的适宜穗数,平均每穗粒数和千粒重三个因素构成的。1973年以前,我场小麦产量由四、五百斤上升到七、八百斤,在由低产变高产的过程中,由于地力、肥水等条件的限制,亩穗数不容易达到高限,产量随亩穗数的增加而提高,故以“穗多取胜”是提高产量的重要途径。几年来,我们不断改进生产条件,培肥地力,使土壤有机
In the calendar year, I planted 200 mu of wheat, and since 1974, it has been stable for more than four years in a row since 1977. In 1977, 196 mu of wheat received a good yield of 1,058 kg per mu under adverse climatic conditions. Years of practice has proved that at present we planted Tai Shan No. 1, Yannong 685 and other varieties, as long as properly cultivated, you can yield more than a thousand pounds. Our experience is: First, the unity of “three highs” Wheat grain yield per unit area by the appropriate number of spikes, the average grain number per spike and 1000 grain weight of three factors. Before 1973, the output of wheat in our field rose from four or five pounds to seven or eight pounds. During the period from low yield to high yield, due to the limitation of soil fertility and other conditions, the number of ears per acre was not easy to reach the upper limit. The output With the increase in the number of acres of spikes and increase, so to “win more than spike” is an important way to increase production. Over the past few years, we continue to improve production conditions, fertilize fertility, make the soil organic
