夏播小麦大部种在丘陵旱地,土薄肥少就成为主要矛盾。为了研究夏播小麦适宜的基肥、追肥用量和氮、磷配合比例,达到增产增收,我们进行了施肥试验。一、试验设计与处理在榆次县庄子大队进行,土壤为下中等,海拔910米。供试品种为夏麦1号,前茬冬小麦。7月10日播种,每亩播量40斤。行距7寸,犁开沟、手溜子。过磷酸钙和农家肥作基肥,7月24日三叶期用尿素追肥并浇水,7月20日中耕一次,8月10日浇第二次水,10月7日收获,生育期88天。试验设计见表1。小区宽10尺、长30尺,面积300平方尺,随机排列,重复2次,加保护行共1亩。
Summer sowing most of the wheat in the hilly drylands, thin soil less fat has become the main contradiction. In order to study the summer sowing wheat appropriate basal fertilizer, topdressing amount and the proportion of nitrogen and phosphorus, to increase yield, we conducted a fertilization experiment. First, the experimental design and processing carried out in the Zhuangzi brigade in Yuci County, the soil is under the middle, 910 meters above sea level. Test varieties for the summer wheat 1, before the winter wheat. July 10 sowing, sowing 40 acres per mu. 7-inch spacing, plow ditches, hand slips. Superphosphate and peasant fertilizer for the basal fertilizer, July 24 clover top with urea top dressing and watering, cultivating once on July 20, August 10 pouring the second water, October 7 harvest, growth period of 88 days . The experimental design is shown in Table 1. Residential area 10 feet wide, 30 feet long, an area of 300 square feet, arranged randomly, repeat 2 times, plus a total protection of 1 acre line.
