高粱为我区主要粮食作物之一,在粮食生产中占有一定的地位。全区的平原、丘陵半山区、低洼盐碱及风砂地区都有种植。由于地势复杂,土壤类型、自然条件、生产条件和技术措施差异较大,在全区产量上形成了高产稳产、高而不稳、不高不稳三种类型。在毛主席革命路线的指引下,我们总结了群众经验,开展了综合研究,以便摸清高粱高产稳产的生物学指标与技术措施的关系,为高粱增产提供科学依据。一、高粱高产稳产生物学指标的探讨 (一)亩产超千斤的产量构成因素我们分析了历年亩产超千斤地块的产量构成因素,看出亩产1,000-1,200斤的每亩穗数在6,755-8,356个,穗粒数多在2,004粒以上,单穗粒重64克以上,千粒重27克以上;亩产1,600斤左右的,每亩穗数12,000个,每穗粒数2,728粒左右,单穗粒重80.8克,千
Sorghum is one of the main grain crops in our region, occupying a certain position in grain production. The plains, hilly Mid-Levels, low-lying saline-alkali sand and sand areas are planted. Due to the complex topography, different types of soil, natural conditions, production conditions and technical measures, there are three types of high-yield and high-yield, high and unsteady, and high instability in the yield of the whole region. Under the guidance of Chairman Mao’s revolutionary line, we summed up the mass experience and carried out a comprehensive study in order to find out the relationship between the biological indicators and technical measures for the high and stable yield of sorghum, and provide a scientific basis for sorghum production. First, the high yield and stability of sorghum biological indicators (A) super-yield per kilogram of production factors We analyzed over the past years overweight production of large plots yield factors, see per mu 1,000-1,200 pounds per acre in the 6,755-8,356, more than 2,004 grains per spike, more than 64 grams per spike and more than 27 grams per thousand. The area of per mu is 1,600 kg, 12,000 per acre and 2,728 grains per spike Spike grain weight 80.8 grams, thousand
