Problems solved by technology

There are many types of seed coating agents on the market today, but because most of the seed coating agents are only aimed at plant diseases and insect pests, for the micro-endosperm corn seeds that lack endosperm and cause nutritional deficiencies during seed germination, the effect of promoting emergence is not very large; and Since the micro-endosperm corn seed has less endosperm, the embryo is very vulnerable to damage due to the lack of endosperm protection. Now the commercially available seed coating agents have certain phytotoxicity to it

Embodiment 1-4

[0018] 1. The composition and content of embodiment 1-4 kinds of coating agents are shown in Table 1.

[0019] 2. the preparation method of embodiment 1-4 is that ferrous sulfate and EDTA-2Na are fully reacted with 30% water boiling of water yield in the seed coating formulation and become ferric salt, pour in the preparation pot of sand mill; Dissolve the film-forming agent in hot water with 50% of the water in the seed coating formula and transfer it to the preparation pot of the sand mill; add 20% of the water in the seed coating formula for imidacloprid and carbendazim to dissolve in the surfactant Then pour it into the preparation pot; add the remaining components into the preparation pot according to the formula ratio, grind each component to about 5 microns with a sand mill, and transfer it to a high-speed homogenizer to fully homogenize it to obtain a suspension-like finished product.

[0020] 3. The coating method of embodiment 1-4 is manual coating method, takes the ...

Embodiment 5

[0022] Present embodiment is the field test effect of the special seed coating agent for microendosperm corn of the present invention:

[0023] 1 Experimental design:

[0024] The seed coating agent used in the test is one of the seed coating agents of the present invention. At the same time, another seed coating agent, the foreign advanced Shileshi seed coating agent, was used as the control 1, and no coating was set as the control 2.

[0025] 2 The experimental land is the experimental land of the Agricultural College of Guangxi University.

[0026] 3. The tested seeds are micro-endosperm corn seeds, the endosperm content is only about 54%, and the starch content is about 10%. Wherein: embodiment 1 is the seed of microendosperm maize genotype 1, sowed on February 3, 2008; Embodiment 2 is the seed of microendosperm maize genotype 2, sowed on June 2, 2008; Embodiment 3 is the seed of microendosperm maize genotype 3, sowed on August 21, 2008; Embodiment 4 is the seed of micro...

Abstract

The invention discloses a special seed coating agent for micro-endosperm corns, which is a suspending agent shape seed coating agent consisting of imidacloprid, carbendazim, ethrel, IBA, 6-BA, cane sugar, potassium dihydrogen phosphate, potassium nitrate and/or ammonium dihydrogen phosphate, magnesium sulplate, microbiological fertilizer, film-forming agent, non-anionic emulsifier, anionic emulsifier, sodium benzoate, ethylene glycol, n-octyl alcohol, acid scarlet or safranine T and the rest of water. The special seed coating agent for micro-endosperm corns provides a plant growth regulator, thereby quickening the activation of the seeds and promoting the sprouting of the seeds; simultaneously, the special seed coating agent provides various nutritive elements when the root systems of the seeds are not formed, therefore, the metabolism of the seeds is accelerated so that the seedlings emerge ahead of time, and the invalid consumption of the seeds in the soil is reduced; the seeds in the soil and after emergence of seedlings are respectively protected with pesticide, thereby preventing the seeds form being harmed from the diseases and the insects; and the seed coating agent is simultaneously suitable for other corn varieties, the emergence of seedlings of which is affected due to insufficient nutrition or difficult root initiation.

Description

technical field [0001] The invention relates to a plant seed coating agent, in particular to a special seed coating agent for micro-endosperm corn for preventing and controlling seedling pests and promoting rooting and difficult emergence of corn. Background technique [0002] Special-purpose corn is the direction of corn development in the 21st century. Micro-endosperm corn is a new type of ultra-high-oil corn germplasm cultivated by Professor Wu Zikai from the Agricultural College of Guangxi University. It is characterized by oil content Extremely high, most have reached more than 20%, and some have exceeded 30%. As we all know, corn oil is a high-quality edible oil with high unsaturated fatty acid content. In the United States, 40% of edible oil is corn oil. Because corn has higher yield than other economic crops and food crops, and at the same time, corn oil has better quality and higher oil content. Maize will become one of the main directions of maize development in t...
