烟台地区小麦播种面积占粮田面积70%左右,一些高产单位,在种植蚰包麦时,多采用重施起身拔节肥。1976年以来,小麦高产地片,逐步更换高产小麦良种—烟农685、泰山一号。但施肥方法仍以起身拔节肥为主,往往造成群体过大,倒伏严重,导致减产。对这些高产小麦品种如何施肥,我们进行了穗粒肥试验研究。1975—1976年为探索烟农685需肥特点,在土壤肥力较高,亩施土粪1.2万斤,前
In Yantai, the sown area of wheat accounts for about 70% of the total area of grain crop. When some high-yielding units planted Baoguang wheat, they rebuffed their crops with heavy fertilizer. Since 1976, wheat has been producing high-yielded land and gradually replaced the high-yielding wheat seed - Yannong 685 and Taishan No.1. However, fertilization methods are still mainly to get up and jointing fertilizer, often resulting in groups are too large, lodging serious, resulting in reduced production. For these high-yield wheat varieties how to fertilize, we conducted a grain-ear fertilizer experiment. 1975-1976 In order to explore the needs of farmers and farmers 685 characteristics of fertilizer in the soil fertility,
