大豆高产虽与栽培条件有关,但与当地的气象条件也是十分密切的,因为高产大豆对降水、日照、气温有一定数量的要求。通过高产大豆与气象条件的研究,进一步模拟丰产的气象条件,对创造大面积的大豆高产稳产田,具有现实意义。 一、材料的来源与产量的划分 本文所使用的品种除1973年的“吉林3号”外,都是“小金黄1号”,均属春大豆,常年4月下旬至5月上旬播种,6月分枝期,7月开花期,8月结荚鼓粒期,9月20日左右成熟,生育期130天左右。大豆生育期间为4—9月,其中6—8月为关键生育时期。选用
Although the high yield of soybean is related to the cultivation conditions, it is also very close to the local meteorological conditions because the high yield soybean has a certain amount of requirements for precipitation, sunshine and temperature. Through the study of high-yielding soybean and meteorological conditions, it is of practical significance to further simulate the meteorological conditions of high-yielding and to create a high-yielding soybean field with large area. First, the source of material and the division of production In addition to the varieties used in 1973, “Jilin No. 3”, are “Golden Golden No. 1” are spring soybean, perennial April to early May sowing, 6 Month branch, flowering in July, August pod drum grain period, September 20 or so maturity, growth period of about 130 days. During the period of soybean growth from April to September, of which 6-8 months as the key growth period. Use
