Embodiment 1

[0020] A medicament for improving cold resistance of cotton, in parts by weight, comprising the following components:

[0021] MnSO 4 28 parts, ZnSO 4 21 parts, CuSO 4 10 parts, KCl 11 parts, abscisic acid 7 parts, vitamin B 0.2 parts, polyvinylpyrrolidone 4 parts, penetrant 2 parts, fungicide 0.1.

[0022] The penetrant is a mixture of sodium isooctyl succinate sulfonate, sodium dodecylbenzene sulfonate and secondary alcohol polyoxyethylene ether sodium sulfate with a mass ratio of 7:5:2

[0023] Dissolve the prepared medicament in water, soak the cotton seeds in it for 2 hours, then take out the seeds and dry them in an incubator at 20°C with a relative humidity of 45% for 36h, then place them in an incubator at 8°C. After it germinates, plant it, and after it grows leaves, spray the medicine directly on the leaves or branches. The ratio of medicine to water during use is 1:20g / L.

Embodiment 2

[0025] A medicament for improving cold resistance of cotton, in parts by weight, comprising the following components:

[0026] MnSO 4 55 parts, ZnSO 4 41.9 parts, CuSO 4 35 parts, 38 parts of KCl, 13 parts of abscisic acid, 0.5 parts of vitamin B, 19 parts of polyvinylpyrrolidone, 5 parts of sodium isooctyl succinic acid sulfonate, and 0.7 parts of fungicide.

[0027] Dissolve the prepared medicament in water, soak the cotton seeds in it for 2 hours, then take out the seeds and dry them in an incubator at 20°C with a relative humidity of 45% for 36h, then place them in an incubator at 8°C. After it germinates, plant it, and after it grows leaves, spray the agent directly on the leaves or branches. The ratio of agent to water during use is 1:30g / L.

Embodiment 3

[0029] A medicament for improving cold resistance of cotton, in parts by weight, comprising the following components:

[0030] MnSO 4 28 parts, ZnSO 4 21 parts, CuSO 4 35 parts, KCl 38 parts, abscisic acid 7 parts, vitamin B 0.5 parts, polyvinylpyrrolidone 4 parts, sodium dodecylbenzene sulfonate 5 parts, fungicide 0.1.

[0031] Dissolve the prepared agent in water, soak the cotton seeds in it for 2-3 hours, then take out the seeds and dry them in an incubator at 20°C with a relative humidity of 45% for 48h, then place them in an incubator at 8°C After promoting its germination, plant it, and after it grows leaves, spray the agent directly on the leaves or branches. The ratio of agent to water during use is 1:25g / L.

Abstract

The invention discloses a pesticidal preparation capable of improving cold resistance of cotton. The pesticidal preparation comprises the following components in parts by weight: 28-55 parts of MnSO4, 21-41.9 parts of ZnSO4, 10-35 parts of CuSO4, 11-38 parts of KCl, 7-13 parts of abscisic acid, 0.2-0.5 part of vitamin B, 4-19 parts of polyvinypyrrolidone, 2-5 parts of a penetrating agent and 0.1-0.7 part of a bactericide. After the pesticidal preparation is used for treating the cotton, the cold resistance of the cotton can be effectively improved, and therefore, the germination rate of the cotton under a cold condition can be increased; moreover, the pesticidal preparation can also provide necessary elements required for the growth for the cotton.

Description

technical field [0001] The invention relates to the field of cotton planting, in particular to a medicament for improving the cold resistance of cotton and its application method. Background technique [0002] During the growth and development of plants, they will be stressed by adversity conditions such as drought, high temperature, low temperature, and salt damage. Among them, low temperature is one of the common stresses that affect the growth and development of crops. The damage is particularly prominent in the growth of winter and spring crops. Due to different degrees of low temperature damage, production was reduced or even necrosis. Low temperature stress may have different effects in various stages of plant growth and development: from sowing to germination, low temperature will cause no germination or germination delay; In the plant stage, low temperature will lead to the reduction of chlorophyll content, the leaves will gradually turn yellow and wither, and even ...
