Embodiment 1

[0032] Example 1 Screening test

[0033] The seed dressing fertilizer synergist containing vitamins and alginic acid was tested indoors to screen out the synergistic substances and the most suitable amount.

[0034] Screening of synergistic substances

[0035] 1. Test site: Linyi R&D Center of Sinochem Agriculture, Linyi City, Shandong Province

[0036] 2. Test varieties: Dika 653, Wansheng 69, Zeyu 8911

[0037] 3. Test time: April 1, 2021 - May 20, 2021

[0038] 4. Experimental design: Simulate high temperature, high humidity and stuffy planting conditions indoors: simulated temperature is 30°C, relative soil moisture content is 85%, soil moisture content is 24%, and field water holding capacity is 30%. Artificial climate incubator is used.

[0039] The experiment set up 5 treatments, namely:

[0040] Treatment 1: blank control CK, without seed dressing;

[0041] Treatment 2: GW-1 simple vitamin E seed dressing;

[0042] Treatment 3: GW-2 elemental calcium alginate f...

Embodiment 2

[0055] Field verification test:

[0056] Get GW-4 among the embodiment 1 and carry out secondary seed-dressing treatment to the seed, non-finished product verification so add talcum powder to ensure seeding quality when mechanical sowing.

[0057] 1. Test location: Gaomi City, Shandong Province

[0058] 2. The variety tested: Zeyu 8911

[0059] 3. Test time: June 23, 2021-July 10, 2021. After sowing, the high temperature can reach 32°C. The test field is flooded with flood irrigation, and the relative soil moisture content is about 80%.

[0060] 4. Experimental design:

[0061] Three treatments were set up in the experiment, namely:

[0062] Treatment 1: blank control CK, without seed dressing;

[0063] Treatment 2: use ordinary seed dressing fertilizer CK1 (10ml of ordinary seed dressing fertilizer diluted to 30ml, corresponding to 1.5Kg of seed dressing), and use a seed coating machine for secondary seed dressing;

[0064] Treatment 3: use the GW-4 of Example 1 (10ml sy...

Embodiment 3

[0069] Field verification test:

[0070] Get the GW-4 of embodiment 1 and carry out secondary seed dressing process to the seed, non-finished product verification so add talcum powder when mechanical seeding to ensure seeding quality.

[0071] 1. Test location: Wuqiang County, Hebei Province

[0072] 2. The tested variety: Wansheng 69

[0073] 3. Test time: June 19, 2021-June 27, 2021. After sowing, the high temperature can reach 38°C. The test field is flooded with flood irrigation, and the relative soil moisture content is about 80%.

[0074] 4. Experimental design:

[0075] Three treatments were set up in the experiment, namely:

[0076] Treatment 1: blank control CK, without seed dressing;

[0077] Treatment 2: use ordinary seed dressing fertilizer CK1 (10ml of ordinary seed dressing fertilizer diluted to 30ml, corresponding to 1.5Kg of seed dressing), and use a seed coating machine for secondary seed dressing;

[0078] Treatment 3: use the GW-4 of Example 1 (10ml syn...

Abstract

The invention provides a seed dressing fertilizer synergist capable of improving high temperature and high humidity resistance of corn seeds. The seed dressing fertilizer synergist comprises vitamins and alginic acid. The seed dressing fertilizer synergist provided by the invention can significantly improve the seed vigor in a high-temperature and high-humidity rotten seed adverse environment and promote the field emergence rate of seeds; meanwhile, the seed dressing fertilizer synergist provided by the invention is low in production cost, does not need evaporation, drying, granulation and other processing procedures in a production process, is low in investment, and can improve the green effect of a fertilizer and reduce pollution to the environment; accurate and efficient fertilization is achieved, nutrient elements can be completely absorbed by the seeds after seed dressing and be stored in the seeds, physiological metabolism of the seeds is adjusted, and improvement of seed vitality is promoted; and meanwhile, mechanical damage of high temperature and high humidity to the seeds is relieved.

Description

technical field [0001] The application relates to the technical field of agricultural planting, in particular to a seed-dressing fertilizer synergist for improving the ability of corn seeds to resist high temperature and high humidity. Background technique [0002] Corn is an important food crop in my country and even the world, as well as high-quality feed and important chemical raw materials. Therefore, the development of corn production is of great significance to the development of the national economy and the improvement of people's living standards. In recent years, with the continuous warming of the global climate, the frequency of abnormally high temperature weather in my country's main corn producing areas has become higher and higher, and the degree of harm has become more and more significant; Scalds can only take root but no buds can be seen; in addition, the rainfall in the summer sowing area is greater than 200mm or a rainfall of 150mm or continuous rain is very...
