四年来,我县广大贫下中农和科技人员,围绕穗多、穗大、粒重三个增产因素,在小麦种、管、收方面,大搞科学实验,初步摸索出了一些高产栽培经验。(一)适期早播早播可以充分利用底墒,早出苗,早生长,早分蘗,早发育,有利于保全苗、育壮苗,减轻麦秆蝇为害。据公会公社公会大队试验,4月7日播种,底墒足,墒情好,苗全苗壮,平均亩产500斤;4月27日播种,亩产只有387.5斤,早种较晚种增产29.1%。战海公社阳坡大队,在春墒基本相同的情况下,4月10日播种的亩产766斤,4月15日播种的亩产533斤,早种比晚种增产43.9%。
In the past four years, the majority of poor and middle-level peasants and scientific and technological personnel in our county have made preliminary scientific discoveries of some high-yielding cultivation practices based on three factors of increasing spike, spike and grain weight. (A) of the early sowing date Early sowing can make full use of soil moisture, early emergence, early growth, early tillering, early development, is conducive to the preservation of seedlings, nurturing seedlings, reduce the damage of the flies. According to the Society Association brigade trial, April 7 planting, at the end enough moisture, good soil moisture, seedlings all seedlings, the average yield 500 kg; April 27 sowing, only 387.5 kg per mu, as early as late varieties increased 29.1% . The Yangpo Brigade of the Zhanhai Commune commuted 536 kilograms of mu per month on April 10 under the same basic conditions of spring and sowing. The yield per mu was 533 kilos on April 15, an increase of 43.9% over the early planting.
