Embodiment 1

[0019] A special coating agent for cucumber, the weight percentage of its raw material components comprises: avermectin 2%, Bordeaux mixture 10%, fludioxonil 1%, GA 3 0.01%, Konjac Glucomannan 1%, Na 2 B 8 o 13 4H 2 O 0.5%. The rest is filled with clay.

[0020] Described coloring agent is amaranth, and coloring agent weight percent is 1.5%,

[0021] The material components of the special coating agent were mixed and ultrafinely pulverized, pulverized by a micronizer for 5 minutes, and the particles were pulverized to 20 μm. The ratio of the mass of the special coating agent to the mass of the seeds is 1:100, and the seeds are coated and dried in air.

Embodiment 2

[0023] The weight percent of its raw material component comprises: Abamectin 8%, Bordeaux mixture 20%, fludioxonil 5%, GA 3 0.015%, Konjac Glucomannan 6%, Na 2 B 8 o 13 4H 2 O 3%. The rest is filled with clay.

[0024] The colorant is a mixture of amaranth, carmine and erythrosine, and the weight percentage of the colorant is 1.5-5%.

[0025] The preparation method is as follows: the special coating agent is mixed according to the material components for ultrafine pulverization, pulverized by a micronizer for 10 minutes, and the particles are pulverized to 120 μm. The ratio of the mass of the special coating agent to the mass of the seeds is 1:300, and the seeds are coated and dried in air.

Embodiment 3

[0027] The percentage by weight of its raw material components of a special coating agent for cucumber comprises: konjac glucomannan 4%, abamectin 5%, Bordeaux mixture 15%, fludioxonil 3%, GA 3 0.01%, Na 2 B 8 o 13 4H 2 O 2%. The rest is filled with clay.

[0028] Described coloring agent is tartrazine, and coloring agent weight percentage is 3%.

[0029] The material components of the special coating agent were mixed and ultrafinely pulverized, pulverized by a micronizer for 7 minutes, and the particles were pulverized to 80 μm. The ratio of the mass of the special coating agent to the mass of the seeds is 1:200, and the seeds are coated and dried in air.

[0030] Analysis of seed germination and growth under different treatments. The cucumber seeds treated with the coating agent in Examples 1-3 were taken as the experimental groups, which were respectively recorded as experimental groups 1, 2, and 3, and the cucumber seeds of the control group were not subjected to an...

Abstract

The invention provides a special coating agent for cucumbers and a preparation method thereof, the formula of which is: abamectin 2-8%, Bordeaux mixture 10-20%, fludioxonil 1-5%, gibberellin 0.01-0.015%, Na2B8O13·4H2O 0.5~3%, konjac glucomannan 1~6%, coloring agent 2~6%, and the rest is filled with clay. Superfinely pulverize the material components of the special coating agent, use a micronizer to pulverize for 5-10 minutes, and pulverize the particles to 20-120 μm. The ratio of special coating agent mass to seed mass is 1:100~1:300. It can effectively control cucumber damping-off, blight, downy mildew, gray mold, angular leaf spot, nematode and other seedling diseases and insect pests, improve the emergence rate and survival rate of cucumber, and promote the growth of seedlings at the seedling stage.

Description

technical field [0001] The invention belongs to the field of agricultural production, and in particular relates to a special coating agent for cucumbers and a preparation method. Background technique [0002] Cucumber is a worldwide staple vegetable, and occupies an important position in my country's protected vegetable cultivation. Due to its special farming methods, protected cultivation generally occurs secondary soil salinization, acidification, plant autotoxicity and other hazards. Due to the poor uniformity of cucumber seed germination and seedling stage, resistance to diseases and insect pests, and stress resistance, it often leads to a general yield reduction of 5-15%, and a serious yield reduction of 30-50%, which affects yield and quality. At the same time, cucumber seedlings are prone to damping-off, blight, bacterial angular spot, downy mildew, gray mold, and root-knot nematode. After wintering, it spreads in the field through irrigation, wind and rain, airflow,...
