摘要
选用春小麦克丰12,结合气候条件分析研究4种不同土壤类型的土壤肥力和含水量对产量的影响效应。结果表明:3个土壤类型产量水平为沙壤质黑土>淋溶黑钙土>草甸黑钙土,产量分别为6 633.6、5305.8和5 261.4 kg.hm-2。这是因为哈尔滨地区沙壤质黑土土壤含水量适宜小麦生长,有效利用肥力,产量较高;克山农场试验区淋溶黑钙土超出小麦生长适宜土壤含水量、牙克石试验区草甸黑钙土低于适宜土壤含水量,均未能有效利用肥力,未能发挥其潜力。
Selecting spring wheat variety Kefeng 12 to study the effect of three different type soils on the yield combining climate condition.The results showed that the yield order was black sand loamy 〉leached chernozem meadow chernozem in three soil types,the yields of Kefeng 12 were 6 633.6,5 305.8 and 5 261.4 kg·hm^-2respectively.Kefeng 12 got higher yield in Harbin area due to fertility effective use and better moisture content of black sand loamy,the soil moisture content of Keshan farm leached chernozem was higher than the suitable soil moisture content for wheat growing,the meadow chernozem moisture content of Yakeshi area was lower than the suitable soil moisture content for wheat growing,so the two kinds of soils could not use fertility effectively and the variety could not play yield potential.
