渭北旱塬夏闲地习用浅—深—浅翻耕,合口耱地过伏。翻耕次数多,费工费时,蓄水保墒效果差,影响小麦生长。为了探索省工、保墒耕作法,1982—85年我们进行了如下试验。一、试验方法试验设在蒲城孙镇,位于渭北“旱腰带”,土壤为垆土。小区面积0.33亩,重复3次。1983年增设大面积示范点2处,计1,000亩;1984年增至5处,计10,000亩。供试品种为渭麦4号、秦麦1号、秦麦3号。 Weibei arid highland summer and leisure to use shallow - deep - shallow tillage, co - mouth overvoltage. Tillage frequency, labor costs, water retention effect is poor, affecting wheat growth. In order to explore the provincial labor, conservation of tillage farming, 1982-85 we conducted the following tests. First, the test method The test is located in Pucheng Sun Town, located in Weibei “dry belt”, the soil is soil. Community area 0.33 acres, repeated 3 times. In 1983, an additional 2 large-scale demonstration sites were set up, measuring 1,000 mu; in 1984, it was increased to 5 and 10,000 mu. Test varieties Wei Mai 4, Qin wheat 1, Qin wheat 3.
