浙江省1959—1960年小麦的增产幅度是史无前例的,增产关键之一是在于群众进一步掌握了合理密植的技术。两年来全省大力推广宽畦阔幅条播,每亩播种量一般达到15—25斤,比过去点播每亩5—7斤、条播每亩8—10斤,增加1—4倍。采用宽畦阔幅条播后,畦宽由4—6尺加宽到6—12尺,播幅一般为0.4—0.6尺,最宽为2尺,幅距一般为5—6寸,土地利用率从过去的40—60%,提高到80—90%。由于密植程度普遍提高,因而小麦产量获得空前丰收。为了探求小麦合理密植的范围、密植与植株生长发育的关系以及密植后相应的栽培技术措施,以保证单位面积内最大限度的穗数、每穗粒数和粒重,我所特进行了小麦密植问题的调查与研究。
The wheat yield increase in Zhejiang Province from 1959 to 1960 was unprecedented in history. One of the keys to increasing production is that the masses have further mastered the technology of close planting. In the past two years, the province has vigorously promoted broad-leaved broad-leaved sowing, with seeding rates generally reaching 15-25 pounds per mu, 5-7 kg per mu than in the past, and 8-10 kg per mu per mu, an increase of 1-4 times. With wide 畦 wide format broadcast, 畦 wide from 4-6 feet widened to 6-12 feet, sowing is generally 0.4-0.6 feet, the widest 2 feet, the general width of 5-6 inches, land utilization From 40-60% in the past to 80-90%. As a result of the general increase in the density of colonies, wheat yields have achieved an unprecedented harvest. In order to explore the range of reasonable close planting of wheat, the relationship between close planting and plant growth and development, and the corresponding cultivation techniques after close planting, in order to ensure the maximum per unit area of the panicle, grain number per panicle and grain weight, Question investigation and research.
