specific Embodiment approach 1

[0032] Specific embodiment one: present embodiment a kind of method that improves corn seed germination, growth, carries out according to the following steps:

[0033] 1. Seed surface disinfection: select corn seeds with full grains and no pests and diseases, disinfect them with sodium hypochlorite solution, rinse them with ultrapure water, and put them on filter paper to dry naturally;

[0034] 2. Preparation of seed soaking agent: Dissolve nano-zinc oxide particles in water and perform ultrasonic mixing to obtain a concentration of 20-100 mg·L -1 Nano-zinc oxide suspension, i.e. seed soaking agent;

[0035] 3. Oscillating seed soaking treatment: immerse the corn seeds treated in step 1 in the seed soaking agent obtained in step 2, then vibrate in a constant temperature oscillator, and then sow seeds to complete the method for improving the germination and growth of corn seeds.

specific Embodiment approach 2

[0036] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the mass fraction of sodium hypochlorite solution in step one is 1%. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0037] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: in step 1, the disinfection time is 30 minutes, then rinse with ultrapure water for 5-6 times, and then air-dry for 24 hours. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a method for improving germination and growth of corn seeds and relates to the field of crop planting. The method aims to solve the technical problems of low germination rate and long germination period of existing corn seeds. The method comprises the steps of 1, sterilizing the surfaces of the seeds; 2, preparing a seed soaking agent; 3, performing vibrated seed soaking treatment. The method can shorten the average time of seed germination and increase the germination rate, germination vigor, germination index and vigor index of the seeds. The growth and elongation ofa root system and germs are boosted; the activity of hexokinase and uridine diphosphate glucose pyrophosphorylase is obviously increased, the activity of aldolase is reduced, the activity of phosphofructokinase is maintained at a relatively normal level, the glycolysis metabolism and the biosynthesis process of cell walls are promoted, and metabolic products and energy are provided for the germination and growth of the seeds. The method is used for promoting the germination and growth of the corn seeds.

Description

technical field [0001] The invention relates to the field of crop planting. Background technique [0002] Maize (Zea mays L.) belongs to the Gramineae family and is an important grain, economy, and feed crop with high yield, strong adaptability, and wide distribution. It has become the grain product with the largest production potential and trade volume. . my country is the second largest corn producer in the world, and corn plays an important role in my country's agricultural production and national economy. Corn production is directly related to my country's food security issues. With the increasing population, the area of ​​arable land is decreasing year by year, soil fertility is declining, resources are scarce and degraded, climate extremes and environmental pollution are intensified. The modernization of consumption and sustainable agriculture are becoming more and more important. my country's corn mainly depends on increasing the yield per unit area to increase the ...
