Embodiment 1

[0013] Add 0.1 kg of uniconazole and 2.4 kg of sodium nitrophenolate into a dry powder mixer and mix for 20 minutes, then add 12 kg of zinc sulfate heptahydrate, and mix for 45 minutes to obtain the seed soaking agent of the present invention. When soaking the seeds, after disinfecting and washing the corn seeds, mix 1g of soaking agent with 3kg of water to soak 1kg of seeds, soak the seeds at 20°C-30°C for 18h, filter the liquid medicine after soaking and sow directly.

Embodiment 2

[0015] Add 0.11 kg of uniconazole and 2.5 kg of sodium nitrophenolate into a dry powder mixer and mix for 20 minutes, then add 12.5 kg of zinc sulfate heptahydrate, and mix for 45 minutes to obtain the seed soaking agent of the present invention. When soaking the seeds, after disinfecting and washing the corn seeds, mix 1g of soaking agent with 3kg of water to soak 1kg of seeds, soak the seeds at 20°C-30°C for 18h, filter the liquid medicine after soaking and sow directly.

Embodiment 3

[0017] Add 0.12 kg of uniconazole and 2.7 kg of sodium nitrophenolate into a dry powder mixer and mix for 20 minutes, then add 13 kg of zinc sulfate heptahydrate, and mix for 45 minutes to obtain the seed soaking agent of the present invention. When soaking the seeds, after disinfecting and washing the corn seeds, mix 1g of soaking agent with 3kg of water to soak 1kg of seeds, soak the seeds at 20°C-30°C for 18h, filter the liquid medicine after soaking and sow directly.

Abstract

The invention discloses a composite type corn seed soaking agent and a use method thereof. The composite type corn seed soaking agent is prepared by fully mixing plant growth regulators and a trace element, specifically fully mixing uniconazole, compound sodium nitrophenolate and zinc sulfate heptahydrate. The use method comprises after disinfecting and washing clearly corn seeds, blending each 1 g of the seed soaking agent with 3 kg of water, soaking 1 kg of the seeds, carrying out seed soaking for 18 h at the temperature of 20 DEG C-30 DEG C, after seed soaking, filtering the drug liquid clearly, and directly seeding. Uniconazole in the seed soaking agent can effectively promote roots and strengthen seedlings and increase lodging resistance of corn by shortening stem base internodes, compound sodium nitrophenolate can effectively alleviate negative effects of single use of uniconazole, and zinc sulfate heptahydrate can effectively prevent a zinc deficiency syndrome.

Description

technical field [0001] The invention relates to a compound seed soaking agent for corn, in particular to a soaking seed treatment preparation suitable for corn, with plant growth regulators and trace elements as active ingredients. Background technique [0002] Corn is one of the main food crops in my country, the main source of livestock feed, and also an important industrial raw material. Maize is vulnerable to drought and floods in the early growth stage, and lodging problems are prone to occur in the late growth stage. At present, growing strong seedlings and lodging resistance are important means to increase maize yield. [0003] To solve the above problems, the traditional methods are seed coating, seed dressing and soil disinfection. Seed coating has the disadvantages of high technical requirements and complicated operations. Seed dressing has the disadvantage that it is difficult to stir evenly and damage the seeds. Soil disinfection has the disadvantages of larg...
