为了验证黑龙江大地光辉农业科技开发有限公司研制生产的大地光辉叶面肥在大豆作物上的应用效果,并探索其使用方法,在黑龙江省土肥站安排下,特在海伦市进行了此试验。1材料和方法大豆品种为垦农18,小区试验3个处理,3次重复,随机排列,试验小区采用6行区,行长10m,小区面积40.8m~2。处理1:当地常规施肥,尿素2kg/667m~2+磷酸二铵10kg/667m~2+硫酸钾3kg/667m~2基础上,初花期用大地光辉叶面肥稀释1000倍喷施。处理2:当地常规施肥,尿素2kg/667m~2+磷酸二铵10kg/ 667m~2+硫酸钾3kg/667m~2基础上,与处理1同期喷施等量清水。处理3:当地常规施肥,尿素2kg/
In order to verify the glorious Agricultural Science and Technology Development Co., Ltd. of Heilongjiang Dadi brilliant earth fertilizer application effects on soybean crops and explore its use, in Heilongjiang Fertilizer Station arrangements, especially in Helen city conducted this test. MATERIALS AND METHODS Soybean cultivars were cultivated in Kennong 18 and plots. Three treatments were repeated and randomly arranged in three plots. The test plot adopted a 6-row area with a governor of 10m and a plot area of 40.8m 2. Treatment 1: Local conventional fertilization, urea 2kg / 667m ~ 2 + DAP 10kg / 667m ~ 2 + potassium sulfate 3kg / 667m ~ 2 based on the first flowering with the earth glow foliar diluted 1000 times spraying. Treatment 2: The local routine fertilization, urea 2kg / 667m ~ 2 + DAP 10kg / 667m ~ 2 + potassium sulfate 3kg / 667m ~ 2 based on the same treatment with the same amount of water sprayed the same time. Treatment 3: Local conventional fertilization, urea 2kg /
