Embodiment 1
[0018] Embodiment 1: a kind of method that improves wheat water and nutrient use efficiency, comprises the following steps: (1) utilizes chlormequat (CCC) and manganese sulfate mixed solution to soak seeds before wheat sowing, soaking time is 12 hours. Wherein the soaking concentration of CCC is 2g / L, and the soaking concentration of manganese sulfate is 0.05%; (2) in the early stage of wheat grain filling, spray urea, manganese and 6-benzylaminopurine (6-BA) mixed solution, the concentration of urea The concentration of manganese sulfate is 1.2%, the concentration of manganese sulfate is 0.1%, and the concentration of 6-BA is 0.1g / L.
Embodiment 2
[0019] Embodiment 2: a method for improving wheat water and nutrient use efficiency, comprising the following steps: (1) before sowing wheat, utilize chlormequat (CCC) and manganese sulfate mixed solution to soak the seeds, and the soaking time is 10 hours. Wherein the concentration of soaking seeds of CCC is 2g / L, and the concentration of soaking seeds of manganese sulfate is 0.1%; (2) spray CCC at the stage of turning green of wheat, and the spraying concentration of CCC is 2g / L; (3) at the early stage of wheat grain filling, spray A mixed solution of urea, manganese and 6-benzylaminopurine (6-BA) was applied, the concentration of urea was 2.0%, the concentration of manganese sulfate was 0.2%, and the concentration of 6-BA was 0.1 g / L.
Embodiment 3
[0020] Embodiment 3: a kind of method that improves wheat water and nutrient use efficiency, comprises the following steps: (1) utilizes chlormequat (CCC) and manganese sulfate mixed solution to soak seeds before wheat sowing, soaking time is 12 hours. Wherein the soaking concentration of CCC is 4g / L, and the soaking concentration of manganese sulfate is 0.08%; (2) spray CCC in the period of turning green of wheat, and the spraying concentration of CCC is between 3g / L; (3) in the initial stage of wheat grain filling , spraying urea, manganese and 6-benzylaminopurine (6-BA) mixed solution, the concentration of urea is 1.5%, the concentration of manganese sulfate is 0.2%, and the concentration of 6-BA is 0.08g / L.
