Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of herbicide spraying protection, and particularly relates to a cotton inter-row herbicide spraying shielding device capable of effectively protecting plants. BACKGROUND

[0002] Cotton field weeding effect and weeding cost directly affect cotton unit area yield and economic benefits. Traditional manual weeding has the problems of high labor cost, high intensity and high cost, which is one of the important reasons for the deterioration of cotton production income and low comparative benefit in recent years. The method of spraying herbicides can greatly reduce the weeding cost. However, there is no special herbicide for cotton after seedling on the market at present, and generally only broad-spectrum herbicides can be used. If the operation is not proper, the herbicide is easy to drift to the cotton, causing damage to the cotton and polluting the environment. In addition, in the process of spraying, in order to prevent the herbicide from drifting to the cotton, the weeds near the roots of the cotton cannot be sprayed, and auxiliary manual weeding is still needed. In addition, the cotton plant has branches, and reproductive organs such as flower buds and bolls grow on the branches. The existing herbicide shielding device is easy to cause damage to the cotton leaves and the reproductive organs, affect the normal growth of the cotton, and reduce the yield.

[0003] The shielding device for spraying herbicides after seedling of crops planted in wide row spacing disclosed in patent document CN213848425U and the shielding device for spraying herbicides after seedling of crops planted in wide row spacing disclosed in patent document CN206776602U can realize post-seeding weeding of crops with different row spacing by adjusting the distance between the baffles. However, due to the particularity of the branches of the cotton, the baffles are easy to cause damage to the cotton plants, and are not suitable for cotton inter-row operation. In addition, if the wind speed is too high during field operation, the herbicide may still drift to the plants or the environment from the back and top of the baffles. At the same time, since the baffles block part of the herbicide, it will inevitably lead to the enrichment and concentration increase of the herbicide on the baffles, and then the herbicide will drip along the lower edge of the baffle to the root part of the crops, resulting in too high concentration of the herbicide at the root part of the cotton, which may cause herbicide phytotoxicity of the crops, thereby affecting the growth and development of the cotton and even causing the death of the cotton seedlings.

[0036] A cotton row spraying herbicide shielding device research that can effectively protect the plant was carried out in A and B two cotton test fields, wherein the cotton row spacing of A test field was 70 cm, and the cotton row spacing of B test field was 80 cm. Herbicide was sprayed at the full-bud stage of cotton, and two treatments were designed: treatment 1, the cotton row spraying herbicide shielding device of the application that can effectively protect the plant; treatment 2, the shielding device for spraying herbicide in row after seedling of wide row spacing planting crops in the public number CN213848425U. The herbicide liquid was prepared according to the specified concentration and red ink was added to mark the drifting and control range of the herbicide; at the same time, the leaf damage and cotton bud shedding of the cotton plant after spraying herbicide were investigated; the wind level was grade 3 when spraying.

[0037] Before spraying herbicide, the treatment 1 firstly covers the operating range adjustment plate 8 to 68cm (A test field) and 78cm (B test field) respectively by rotating the front end double-way internal thread pipe 15, and adjusts the protection range of the baffle 11 to 68cm (A test field) and 78cm (B test field) respectively by rotating the rear end double-way internal thread pipe 16. Meanwhile, the height of the ground hard canvas 18 is adjusted to be just in contact with the ground; the treatment 2 also adjusts its shielding range according to its requirements.

[0038] The test results are shown in Table 1: although the control range is similar to the treatment 2, after using the application, the herbicide is basically not scattered, the damage of cotton plants (leaf damage and cotton bud drop) is greatly reduced, the herbicide concentration around the cotton plants is basically consistent with the prepared herbicide concentration, and no herbicide enrichment is found. It is shown that the application can effectively increase the herbicide control range under the premise of effectively protecting the cotton plants, and lays the foundation for controlling the whole field weeds.
