摘  要：
为了促进南方小麦的高产稳产,从1975年起我院组织省内有关科研单位、院校和部分高产社队进行小麦高产研究及攻千斤联合试验。现将我院近几年的小麦高产栽培研究,并结合淮南地区小麦高产经验,对千斤小麦栽培技术及高产生理进行总结和分析。 我省淮南和苏南地区,冬季气温不很低,小麦越冬期0℃以下的天数,一般只占越冬天数的1/4到1/2,多栽培春性大叶型品种,分蘖期较短,每亩成穗数较少。春季多

摘  要：
Under the condition of plentiful rainfall and serious diseases in the South of Huai River in Jiangsu province, wheat often fails to get high yields there, so the culture for higher yield and its physiological research has been conducted in Nanjiag during 1975—1979. The results are summarized as follows:1. The average yield per mu of the high-yielding plots reached as high as 543.9 kg, 550.6 kg, 518.7 kg and 568.9 kg; in 1978 and 1979 respectively. Such results showed that the structure of dynamic population for average yield of 500-570 kg per mu in "Nanjing No.3"and"7317"varieties required a density of 100—150 thousand seedlings per mu, with a maximum culms up to 800—900 thousand, 350—400 thousand ears, over 40 kernals per head and a weight of 36—40 grams per 1000 grains. Such a sowing density and structure would ensure a normal growth and development of both individuals and population of the plant.2. To control population structure, a proper fertilization was neccessary in order to get high yield. A moderate amount of basic and tiller's fertilizer would benefit the growth of seedlings, and favor the formation of strong tillers. A proper amount of fertilizer applied at the knotting stage would favor the formation of grains, the"heading rate" of tiller and the increasing of the numbers of spikelets.3. Experiments also showed that the maximum leaf area index of high yielding wheat at 6-7, would significantly increase the rate of photosynthesis. The coefficient of photosynthesis rate from booting to filling stages would strongly influence the yield of wheat. The higher yield of 500-570 kg per mu required a maximum biological yield of 1300—1400 kg. Its economic coefficient was 0.44—0.55 and the grain/straw ratio was about 1:1—1:1.2.
