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.

Abstract

The invention belongs to field of agronomic crop cultivation technology, which in detail relates to a method for increasing availability ratio of water and nutrient by wheat and the product formulation. The technical projection comprises following steps: (1) immersing seed with mixing solution of chlormequat (CCC) or paclobutrazol (PP333) and manganese sulfate for 10-12 hours before sowing, sowing after seed drying in shade, the CCC concentration is 2-10 g / l, and the manganese sulfate concentration is 0.05-0.1% if the PP333 concentration is 150-250 mg / l; (2) spraying mixing solution of urea, manganese and 6-benzyl-aminopurine (6-BA) in early filling period, the urea concentration is 1-2%, manganese sulfate concentration is 0.1-0.2%, and the 6-BA concentration is 0.05-0.1 g / l.

Description

Technical field: [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for improving wheat water and nutrient utilization efficiency and a product formula thereof. Background technique: [0002] my country is one of the countries with severe water shortage in the world, and the per capita water resource is only one-fourth of the world's average level. At the same time, my country is also a big waste of water resources. The current utilization coefficient of agricultural irrigation water, which accounts for more than 70% of the total water consumption, is only half of that of developed countries. Therefore, how to improve the utilization efficiency of irrigation and precipitation is an urgent problem to be solved. It is one of the effective ways to improve water use efficiency to research and develop new ways and new products to improve the physiological regulation of crop efficient water use. [0003] It is one of th...
