Embodiment 1

[0026] Recipe: (weight)

[0027] Polyvinyl alcohol 2%

[0028] Gum Arabic 8%

[0029] Polyethylene glycol octylphenyl ether 0.1%

[0030] Ethylene Glycol 5%

[0031] Tributyl Phosphate 1%

[0032] Red pigment 2%

[0033] Ruisheng (Thiamethoxam) 1%

[0034] Cypermethrim 0.5%

[0035] Welford (carboxin thiram) 2%

[0036] Manshikin (Fludioxonil Fludioxonil metalaxyl-M) 1%

[0037] Chitosan 0.1%

[0038] Potash 2%

[0039] water balance

[0040] Preparation:

[0041] Chitosan is dissolved in 1% glacial acetic acid solution with weight concentration, and the content of chitosan is 6g / liter;

[0042] Then polyvinyl alcohol is dissolved in water, and the content of polyvinyl alcohol is 30g / liter;

[0043] Then the above-mentioned mixed material is stirred and mixed with other materials, and finally water is added to make up to 100%, so as to obtain the corn coating agent.

[0044] After the corn seeds are coated with the corn coating agent prepared above, the germinati...

[0046] Recipe: (weight)

[0047] Polyvinyl alcohol 1%

[0048] Gum Arabic 3%

[0049] Polyethylene glycol octylphenyl ether 1%

[0050] Ethylene glycol 2%

[0051] Tributyl Phosphate 0.1%

[0052] Red pigment 1%

[0053] Ruisheng (Thiamethoxam) 0.5%

[0054] Cypermethrim 2%

[0055] Weifu (carboxin thiram) 1%;

[0056]Manshikin (Fludioxonil Fludioxonil metalaxyl-M) 0.1%

[0057] Chitosan 2%;

[0058] Potash 1%

[0059] water balance

[0060] The preparation method is the same as in Example 1.

[0061] After the corn seeds are coated with the corn coating agent prepared above, the germination speed of the corn seeds is accelerated by 0.5 days, the growth of the seedlings is relatively strong, the dry and fresh weight increases, and the control effect of waxy corn diseases and insect pests reaches 90.40%. The ear diameter and the number of grains in the ear were both increased compared with the control, and the yield of maize increased by 10%.

Abstract

The invention provides a seed coating agent of waxy corn, which comprises the following components in percentage by weight: 1 to 2 percent of polyvinyl alcohol, 3 to 8 percent of gum arabic, 0.1 to 1percent of surfactant, 2 to 5 percent of antifreezing agent, 0.1 to 1 percent of defoaming agent, 1 to 2 percent of warning color, 0.5 to 1 percent of thiamethoxam, 0.5 to 2 percent of cypermethrin, 1to 2 percent of carboxin, 0.1 to 1 percent of fludioxonil, 0.1 to 2 percent of chitosan, 1 to 2 percent of potassium fertilizer, and the balance of water. The seed coating agent achieves effective control efficiency to soil insects (cutworms, grubs and the like), stem rot, head smut and aphids, generates obvious control efficiency to diseases and insect damages, and has low dosage. The germination speed of waxy corn seeds is increased by 0.5 day, seedlings grow robustly, the dry fresh weight is increased, and the comprehensive control efficiency of plant diseases and insect pests reaches 90.80 percent; and at the harvest time, the spike length, the spike thickness and the spike grain number are improved compared with a contrast, and the yield of the corn is improved by 10 to 15 percent.

Description

technical field [0001] The invention relates to a seed coating agent, in particular to a seed coating agent for waxy corn seeds. Background technique [0002] Seed coating agents are substances used to coat plant seeds to make them standardized and commercialized and have film-forming properties. It consists of two parts: one part is the supporting auxiliary agent mainly film-forming agent, including film-forming agent, suspending agent, antifreeze agent, preservative, viscosity protection agent, diffusing agent and warning color fuel, etc., its function is to form the following The colloidal dispersion system with water as the carrier has good film-forming properties, stability, slow release and warning color after seed coating; the second is micro-fertilizers, plant growth regulators, Biological agents, insecticides, fungicides, trace elements and other active ingredients can improve the nutritional conditions required for seed germination and the growth environment of se...
