Problems solved by technology

[0003] Because buckwheat is a shallow-rooted plant and the stems are easy to fold, mechanical weeding, herbicide weeding and manual weeding are usually used for weeding. Among them, manual weeding is slow and labor-intensive. Mechanical weeding has the advantage of being fast, but it is particularly easy to damage the roots of buckwheat. , and even uproot the buckwheat along with the weeds
Herbicide weeding is more complicated, and the most commonly used herbicides on the market are Henais and Quick Harvest, but these herbicides are generally effective. Low pesticide content will not achieve the weeding effect, and high content will cause weeds. Resistance to pesticides. Some studies have even shown that when other plants are planted after buckwheat after using the above herbicides, other plants cannot grow normally. This shows that the traditional buckwheat special herbicides have a bad impact on the land and cannot be rotated when planting buckwheat. Other plants, lower farmers income
To sum up, weeding of buckwheat is particularly difficult in agriculture, and even unreasonable weeding methods will affect the yield of buckwheat and other crops

Embodiment 1

[0039] A weeding method for a buckwheat field, characterized in that it comprises the following steps:

[0040] Land weeding before sowing: first apply fully decomposed farmyard manure to the soil to reduce the spread of germs and weeds. 10 days before sowing, combined with rotary soil irrigation, with a depth of 10cm, combined with rotary soil preparation 1 day before sowing to eliminate Weeds, the depth of rotation is 12cm;

[0041] Weeding before seedlings after sowing: Spray Jinchaoer aqueous solution within 24 hours after sowing buckwheat. Jinchaoer aqueous solution is prepared with 720g / L metolachlor at 100mL / acre plus 60kg water. Jinchaoer aqueous solution is applied on the soil surface Form a drug layer, if it rains in one day, respray immediately after the rain;

[0042] Weeding after the seedlings before sealing the ridge: when the weeds grow to 2 to 4 leaves, use 10% quizalofop-p-p-p and add 60kg water to prepare the quizalofop-p-p-p herbicide at the ratio of 120mL...

Embodiment 2

[0045] A weeding method for a buckwheat field, characterized in that it comprises the following steps:

[0046] Weeding the land before sowing: First apply fully decomposed farmyard manure to the soil to reduce the spread of germs and weeds. 15 days before sowing, combined with rotary soil irrigation, the depth of rotary soil is 12cm, and 2 days before sowing combined with rotary soil preparation to eliminate weeds;

[0047] Weeding before seedlings after sowing: Spray Jinchaoer aqueous solution within 24 hours after sowing buckwheat. Jinchaoer aqueous solution is prepared with 720g / L metolachlor at 120mL / acre plus 60kg water. Jinchaoer aqueous solution is applied on the soil surface Form a drug layer;

[0048] Weeding after the seedlings and before sealing the ridge: when the weeds grow to 2 to 4 leaves, use 10% quizalofop-p-p-p and add 60kg water to prepare the quizalofop-p-p-p herbicide at a ratio of 140mL / mu, and weed control Foliage or whole plant spraying;

Embodiment 3

[0051] A weeding method for a buckwheat field, characterized in that it comprises the following steps:

[0052] Land weeding before sowing: first apply fully decomposed farmyard manure to the soil to reduce the spread of germs and weeds. 13 days before sowing, combined with rotary soil irrigation, the depth of rotary soil is 12cm, and 2 days before sowing combined with rotary soil preparation to eliminate weeds;

[0053] Weeding in front of seedlings after sowing: Spray Jindur aqueous solution within 24 hours after sowing buckwheat. The Jindur aqueous solution in this example is formulated with 960g / L of refined metolachlor at 80mL / acre plus 60kg of water , the Jinduer aqueous solution forms a drug layer on the soil surface;

[0054] Weeding after the seedlings and before sealing the ridge: when the weeds grow to 2 to 4 leaves, use 10% quizalofop-p-p-p and add 60kg water to prepare the quizalofop-p-p-p herbicide at a ratio of 130mL / mu to control the weeds. Foliage or whole p...

Abstract

The invention provides a weeding method for a buckwheat field, and relates to the technical field of agriculture. The weeding method for the buckwheat field comprises the steps that farmyard manure is applied to soil firstly, rotary tillage irrigation is combined 10-15 days before sowing, and rotary tillage soil preparation is combined 1-2 days before sowing to kill weeds; after the buckwheat is sown, a Jin chao er aqueous solution or a Jin du er aqueous solution is immediately sprayed to form a pesticide layer on the soil surface; when the weeds grow to have 2-4 leaves, quizalofop-p-ethyl herbicide is sprayed to the weeds; and the weeds which are not killed or missed by the herbicide are manually removed and brought out of the field to be treated. The weeding method for the buckwheat field has high prevention efficiency on grass and broad grass; and meanwhile, the weeding method does not have bad influence on the buckwheat yield, and compared with a buckwheat field not sprayed with the herbicide, the yield can be increased by 50% or above at most through weeding.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for weeding a buckwheat field. Background technique [0002] Buckwheat originated in China and has a long history of cultivation. It is an important miscellaneous grain crop of the genus Buckwheat in the family Polygonaceae. It is an annual or perennial dicotyledonous herb with a short growth period, strong resistance to stress, and extremely cold and barren tolerance. It can be sown multiple times a year. Harvested multiple times. Buckwheat has very high nutritional value, and is known as the king of five grains and the three-down food. There are mainly two cultivated species of sweet buckwheat and tartary buckwheat. There are many nutrients in buckwheat, such as rich lysine, iron, manganese and zinc, etc. In addition, buckwheat is also rich in dietary fiber, so eating more of this kind of food can help promote Gastrointestinal motility, and because it is rich i...
