The invention discloses a weeding composition for preventing and treating weeds in rice fields. The weeding composition comprises active components including oxaziclomefone and indanofan in a weight ratio of 1:0.01 to 1:500, wherein the weight of the active components accounts for 1%-95% of the total weight of the weeding composition. The weeding composition can be in the form of wettable powder, water dispersible granules, a suspending agent, an oil suspending agent, a dried suspending agent, granules, emulsion oil, an emulsion in water, a microemulsion, a suspended emulsion, effervescent granules or effervescent tablets. The compounded weeding composition disclosed by the invention not only has an expanded herbicide controlling spectrum and is capable of preventing and eliminating grassy weeds, sedge weeds and broadleaf weeds at one time, but also has an obvious synergistic effect. The weeding composition disclosed by the invention has a wide range of suitable time for application, can be sprayed to pre-emergent soil and post-emergent stems and leaves, generates a small environmental influence and is quite safe to present and later crops, particularly high in safety to paddy.

The invention discloses a weeding composition for preventing and controlling weeds in a peanut field. The weeding composition comprises active ingredients including sulfentrazone and clethodim in the weight ratio of 0.01:1 to 100:1, and the weight of the active ingredients is 1%-95% of the total weight of the weeding composition. The weeding composition is in a form of wettable powder, water dispersible granule, oil suspending agent, dry suspending agent, granule, missible oil, emulsion in water, microemulsion or suspension emulsion. After the weeding composition is compounded, the herbicide controlling spectrum can be expanded, broadleaf weeds and grassy weeds can be removed, and the weeding composition has remarkable synergism. The weeding composition has a long optimum period of application, can be sprayed to soil before emergence, also can be sprayed to stems and leaves after emergence, has a low influence to the environment, is safe to current crops and afterreap crops, is safe to peanuts and is also suitable for various peanut varieties.

The invention discloses an abacus for a sow's expected delivery date, and mainly relates to the field of sow breeding appliances. It includes a calendar plate and a gestational week plate. A cavity is arranged below each scale line inside the calendar plate, and an identification card is provided in the cavity. The identification card consists of a sliding block at the inner end and a blank card at the outer end. Composition, the width of the sliding block is larger than that of the blank card, and the two are hinged through the connecting shaft, the sliding block is slidably connected with the cavity, and the peripheral side of the calendar disc is provided with a card outlet hole communicating with the cavity, The width of the card outlet hole corresponds to the blank card, and also includes a chassis, which is also circular and is arranged on the side of the calendar disk away from the gestational period disk. connections. The beneficial effect of the present invention is that the calendar disc can be rotated for viewing, and has a compact structure, convenient use, and freely retractable labeling functions, which is beneficial to tracking, viewing and refined feeding during pregnancy.

The invention relates to a weedicide composition and an application method thereof. The composition comprises an active component A and an active component B, wherein the weight ratio of the componentA to the component B is 1:100 to 1:1; the component A is selected from a compound as shown in the following general formula: (the formula is as shown in the description); and the component B is selected from glyphosate as well as salt or ester suitable for agricultural chemistry. The weedicide composition is particularly suitable for preventing and removing weed which has tolerance or resistanceon organophosphorus weedicide, particularly the glyphosate.

The invention discloses a combination used for preventing and removing cornfield noxious weed. The combination is characterized in that: the combination comprises active ingredient composition A and composition B, wherein the composition A is R-2-[4-(5-chloro-3 fluoro-2-oxylpyridine)- phenoxy]-propiolic acid; and the composition B is one of or more than one of 2-[4-methoxyl-6-methyl-1, 3, 5-triazine-2-methyl amido methyl amido sulfonyl] methyl benzoate, thifensulfuron methyl and bensulfuron methyl. The combination provided by the invention has the advantages of wide weed control spectrum, high activity against noxious weed, safety, low toxicity and low residue for crops, safety for following rotation crops, resistance to adverse environments such as low temperature and drought, long working life and convenient use, etc. Meanwhile, the weed control effect of the combination is better than the control effect when the compound A or the compound B is used independently, and the application dose of each active substance is reduced; moreover, the combination is used for just one time and can control the damages caused by various weeds during the entire growing period of wheat, thereby having ideal economic benefit and ecological benefit.
