Embodiment 1

[0024] Embodiment 1: a kind of method that improves corn water use efficiency, comprises the following steps: (1) utilizes gibberellin and zinc sulfate mixed solution to soak seed corn seed (ratio of medicinal liquid consumption and seed consumption is 1: 0.4) 3 hours , wherein the concentration of gibberellin is 20mg / L, and the concentration of zinc sulfate is 0.05%; (2) after the seeds are pulled out, the mixed solution of CCC and zinc sulfate is used to soak the seeds for 6 hours (the ratio of the amount of medicinal solution to the amount of seeds 1:0.6), wherein the concentration of CCC is 2g / L, and the concentration of zinc sulfate is 0.05%; (3) dry in the shade.

Embodiment 2

[0025] Embodiment 2: a kind of method that improves corn water use efficiency, comprises the following steps: (1) utilizes gibberellin and zinc sulfate mixed solution to soak seed corn seed (ratio of medicinal liquid consumption and seed consumption is 1: 0.5) 4 hours , wherein the concentration of gibberellin is 40mg / L, and the concentration of zinc sulfate is 0.1%; (2) after the seeds are pulled out, use PP 333 Seeds were soaked in a mixture of zinc sulfate and zinc sulfate for 8 hours (the ratio of the amount of medicinal solution to the amount of seeds was 1:0.8), where PP 333 The concentration of zinc sulfate is 300mg / L, and the concentration of zinc sulfate is 0.1%; (3) dry in the shade.

Embodiment 3

[0026] Embodiment 3: a kind of method that improves corn water use efficiency, comprises the following steps: (1) utilizes gibberellin and zinc sulfate mixed solution to soak seed corn seed (ratio of medicinal liquid consumption and seed consumption is 1: 0.6) 3.5 hours , wherein the concentration of gibberellin is 30mg / L, and the concentration of zinc sulfate is 0.08%; (2) after the seeds are pulled out, the mixed solution of CCC and zinc sulfate is used to soak the seeds for 7 hours (the ratio of the amount of medicinal solution to the amount of seeds 1:0.7), wherein the concentration of CCC is 3g / L, and the concentration of zinc sulfate is 0.05%; (3) dry in the shade.

Abstract

The invention belongs to field of crop cultivation, and relates to a technology of promoting germination of corn seed and the product formulation. The invention aims to solve problem of low availability ratio of water and nutrient for corn. The technological projection comprises following steps: (1) immersing corn seed with mixing solution of gibberellic acid and zinc sulfate for 3-4 hours, and the concentration of them are between 20 to 40 mg/l and 0.05% to 0.1% respectively; (2) immersing seed with mixing solution of chlormequat (CCC) or paclobutrazol (PP333) and zinc sulfate for 6-8 hours, and the concentration of CCC and PP333 are between 2-4 g/l and 200-300 mg/l respectively, and the concentration of zinc sulfate is 0.05%-0.1%; (3) drying in shade.

Description

Technical field: [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a seed treatment technology for promoting the germination of corn seeds to form strong seedlings and a product formula thereof. Background technique: [0002] Corn is one of the three major food crops cultivated in China, and plays a very important role in my country's food production. Corn is also a crop that requires high water and nutrients. Sufficient water and fertilizer supply is the basis for high-yield and high-quality corn. However, in many areas of my country, especially in the north, water stress is a prominent problem often encountered during the growth of maize. Therefore, how to enhance the stress resistance of maize plants, and then improve the utilization efficiency of irrigation and precipitation during crop growth, is an urgent problem to be solved. It is one of the effective ways to improve the water and nutrient use efficiency of corn t...
