What are the main weeds in the peanut field and what are their names

Peanut planting area is extensive, the occurrence of different weeds in different regions are different, almost all dryland weeds are distributed in peanut fields, mainly gramineous weeds Ma Tang, cattle tendon grass, dog tooth root, white grass, paspalum, dog tail grass, knotweed, hemostatic Ma Tang, barnyard grass, Qianjinzi, dragon claw grass, tiger tail grass, grass grass, etc., sedge weeds fragrant aconite, heteromorphic sedge, sunshine fluttering grass, broken rice sedge, red scale flat grass, flat stalk grass, Japanese weed, etc., Asteraceae weeds spiny cabbage, dandelion, Xanthium, bitter herb, flying sickle, yellow flower song, Artemisia wormwood, Needle trifolium, snakehead intestine, etc., Amaranth retroflex weeds, Amaranth, Amaranth, Amaranth concave, Leaf (cockscomb), etc., Solanaceae weeds Nightshade, Datura, Lanternweed, Lycopodium, Wild Eggplant, Sour Pulp, False Sour Pulp, Weasel Petal Flower, Herbaceous Herb, etc., Polygonaceae Weeds Sorrel Leaf Roots, Flat Accumulation, Amphibian Polygonum Polygonate, Dry Knotweed, etc.; Chenopodaceae weeds, quinoa, quinoa, salsa, broom, etc., in addition to iron amaranth, purslane and so on.

Weeds account for more than 25 in the family, about 13 in Asteraceae and weeds, and there are also Amaranthaceae, Polygonaceae, Chenopodaceae, Solanaceae, etc. The density of fields such as horsetail, dogtail grass, cow tendon grass, barnyard grass, sedge, iron amaranth, purslane, amaranth retroflexus, quinoa, xanthium, nightshade, teff grass and other fields was the largest, and the frequency of horsetail was the main weed in peanut fields.

Let's see what others have to say.

The weeds in the peanut field mainly include: horsetail, cow tendon grass, wild oats, dogtooth root, large teff, small teff, white grass, paspalum, dogtail grass, knotweed, hemostatic horsetail, barnyard grass, goldenrod, dragon claw grass, tiger tail grass, horseweed, etc. It is followed by Asteraceae, Amaranthaceae, Solanaceae, Cyperaceae, Cruciferaceae, Euphorbiaceae, Chenopodaceae, Purslaneaceae, etc.

Northern peanuts are sown in spring and summer, and are cultivated in open fields and mulch. According to surveys in Shandong Province and Beijing Municipality, there are nearly 100 species of weeds in peanut fields, belonging to 32 families. There are more than 20 kinds of weeds that are widely distributed and seriously harmful, including horsetail, ox tendon grass, dogtail grass, barnyard grass, amaranth retroflexus, amaranth concave, purslane, quinoa, iron amaranth, scavenger, Xanthium, hemp, nightshade, sorrel leaf knotweed, mandala, wild watermelon seedlings, broken rice sedge, heteromorphic sedge, Huangying sedge, shepherd's cabbage, attached ground cabbage, bowl flower, spiny green, bitter herb and horsetail horsetail.

Due to the different climate, soil and farming system, different regions generally consist of different types of major weeds.

Peanuts are mostly sown in equal row spacing or wide and narrow rows, and the row spacing and hole spacing are large, which is conducive to the occurrence of weeds, and the hole spacing is relatively small, which is difficult to manually weed. The most harmful to peanuts are the weeds that occur from the time of sowing seedlings to the time when the peanuts are closed. After the closure of the row, the weeds had few seedlings and weak growth, which had little impact on the yield of peanuts.

Generally, 3 or 4 times of manual or mechanical weeding should be carried out before the peanut is sealed, which can control the grass damage, but it is labor-intensive, and the fruit needles are destroyed into the soil, which affects the yield and quality of peanuts. Shandong Province survey, peanut due to grass damage generally reduced yield 5% 10%, serious 15% 20%, or even more, Beijing Miyun County Plant Protection Station in 1979 test proved that the emergence of peanut seedlings from 5 cm and 4 Ma Tang, the final peanut yield was reduced and, the same year the station test proved that on May 19, June 3 and June 25 for 3 times of manual weeding, than after sowing before the application of herbicides without weeding the yield of weeding. It can be seen that the damage of weeds in the early stage is great and the superiority of chemical weeding.

Peanut planting area is extensive, the occurrence of different weeds in different regions are different, almost all dryland weeds are distributed in peanut fields, mainly gramineous weeds Ma Tang, cattle tendon grass, dog tooth root, white grass, paspalum, dog tail grass, knotweed, hemostatic Ma Tang, barnyard grass, Qianjinzi, dragon claw grass, tiger tail grass, grass grass, etc., sedge weeds fragrant aconite, heteromorphic sedge, sunshine fluttering grass, broken rice sedge, red scale flat grass, flat stalk grass, Japanese weed, etc., Asteraceae weeds spiny cabbage, dandelion, Xanthium, bitter herb, flying sickle, yellow flower song, Artemisia wormwood, Needle trifolium, snakehead intestine, etc., Amaranth retroflex weeds, Amaranth, Amaranth, Amaranth concave, Leaf (cockscomb), etc., Solanaceae weeds Nightshade, Datura, Lanternweed, Lycopodium, Wild Eggplant, Sour Pulp, False Sour Pulp, Weasel Petal Flower, Herbaceous Herb, etc., Polygonaceae Weeds Sorrel Leaf Roots, Flat Accumulation, Amphibian Polygonum Polygonate, Dry Knotweed, etc.; Chenopodaceae weeds, quinoa, quinoa, salsa, broom, etc., in addition to iron amaranth, purslane and so on.
