  Grain Filling Characteristics of Jingdan68 and Zhengdan958 under Different Sowing Dates 2013, 3 (10):  1-5.  Abstract + ( 972 )   PDF ( 1149KB )   ( 1283 ) Abstract：Study the change of grain filling rate of Jingdan68 and Zhengdan958 under different sowing dates. Jingdan68 and Zhengdan958 with two sowing dates (14 May, and 13 June) were used in field experiments. The average temperature, maximum and minimum temperature, accumulated temperature during the grain filling stage under spring sowing were 1.22 ℃, 0.54 ℃ and 2.37 ℃, 480.54 ℃ higher than the summer sowing condition. Under spring sowing condition, the 100-grain dry weight of Jingdan68 and Zhengdan958 was 43.03 g and 39.02 g, and 41.17 g and 34.80 g under summer sowing condition; The dry weight of 100-grain at maximum grain filling rate (Wmax), the thermal time needed during the active grain filling period (P) under spring sowing were higher than that of summer sowing condition. Thus, the maximum grain filling rate (Gmax), initial grain filling potential (Ro), the thermal time reaching the maximum filling rate (TGDD) showed opposite trend. The TGDD and P of Zhengdan958 were higher than Jingdan68, but the Wmax, Gmax, Ro performance opposite trend. The study showed that grain filling of Jingdan68 was started as early as Zhengdan958, initial grain filling potential and grain filling rate were higher than Zhengdan958 and the accumulated temperature required for its active grain-filling period was less than Zhengdan958, so final grain dry matter weight significantly higher than Zhengdan958.

  The Impact of Meteorological Factors on the Winter Wheat Yield——the Case Study from Weishan County, Shandong Province 2013, 3 (10):  45-51.  Abstract + ( 1010 )   PDF ( 1982KB )   ( 1081 ) In this paper, using winter wheat yield and meteorological data during 1981-2009 in the Weishan County, Shandong Province, our purpose is to study the impact of meteorological factors (rainfall, sunshine, temperature) on yield. Firstly, analyzing meteorological data simply, and checking the relationship between meteorological factors, we found that there was strong negative correlation between rainfall and sunshine; the authors built the meteorological conception model, and dealt with the relationship between variables, using the orthogonal polynomial method to solve the Fisher integral regression model. The results showed that, rainfall was conducive to increase the yield in the future, the yield increased by 1.65 kg/hm2 to 2.25 kg/hm2 if the rainfall increased 1 mm more than in the normal month. Higher temperature was beneficial to the yield, the yield increased by 272.4 kg/hm2 if the temperature increased 1℃ higher. In winter period, lighting was conducive to the yield; the yield increased by 135.3 kg/hm2 to 166.5 kg/hm2 if the lighting increased 1 hour more. During the turning green period and jointing stage, rainfall in March and April promotes the yield increasing, the yield increased by 4.95 kg/hm2 and 4.2 kg/hm2 if the rainfall increased 1 mm. In this paper, the meteorological yield coefficient could explain how meteorological factors influence the yield of winter wheat. This laid the foundation of methodology for the forecasting winter wheat yield in the future.
