- Abstract:
-
The coupling of water and fertilizer test adopted the design of perpendicularity in jointing stage of the maize indicated that the water was a decisive factor of the maize growth under the conditions of different water and fertilizer.To the influence of the height of maize in jointing stage,water and potassium reached the extremely prominent level,and water > potassium,nitrogen and phosphorus were not prominent.The influence on a leaf area of form in jointing stage of maize of the water-holding capacity of soil reached the extremely prominent level,nitrogen and potassium had reached the prominent level,the influence of the phosphorus is not prominent.Phosphorus had the prominent influence on the root,but to the weight of root is not prominent.The influence of water,nitrogen,potassium on biological quantity of jointing stage of the maize was the positive effect,phosphorus was negative.The irrigation rate of water during the maize jointing stage showed that the rate under controlled low water with high fertilizer was the highest,the rate under controlled high water in the maize jointing stage was lower than low water and media water.Deal with to irrigate water conservancy with to reach most heavy rate,The irrigation rate of treatment 3 was the highest,but the treatment 7 was the lowest.
