川西平原探索小麦高产途径是从调整群体降低基本苗,较多依靠分蘖成穗.试验品种选用“76-3”、川育五号、“凡六”.每亩10万基本苗(低密度)、17万(中密度)、24万(高密度),播幅4寸、空行4寸的条播.小区面积0.05亩,11月10日播种.试验结果看出:1.三个类型的品种都以低密度的(10万基本苗)产量最高,亩产分别为842.0斤、749.6斤,690.8斤,比17万苗的分别增产9.0%、12.4%、8.2%;比24万苗的分别增产10.8%、20.5%.10.7%.2.低密度处理能够达到一定的穗数和较高的穗重,较好地统一了穗数和穗重的矛
Western Sichuan Plain to explore ways to increase the yield of wheat is to reduce the basic population from the adjustment group, more dependent on tillering ear .Test varieties use “76-3 ”, Chuan Yu five, "Where six (Density), 170,000 (medium density), 240,000 (high density), sowing 4-inch, blank line 4-inch broadcast. The plot area of ?? 0.05 acres, sown on November 10. The test results showed that: 1.3 The varieties with the lowest density (100,000 basic seedlings) each had the highest output of 842.0 kg, 749.6 kg and 690.8 kg, respectively, up 9.0%, 12.4% and 8.2% respectively over the figure of 170,000; Seedlings increased by 10.8%, 20.5% .10.7% .2. Low-density treatment can reach a certain number of spikes and higher panicle weight, better uniform number of spike and panicle spear
